○ ○ Article ⓘ Nelonemdaz and Patients With Acute Ischemic Stroke and Mechanical Reperfusion: The RODIN Randomized Clinical Trial ⓘ Importance Nelonemdaz selectively antagonizes the 2B subunit of the N-methyl-d-aspartate glutamate receptor and scavenges free radical species. Objective To evaluate whether nelonemdaz enhances the clinical outcomes of patients with acute ischemic stroke undergoing emergent reperfusion therapy. Design, Setting, and ParticipantsThis multicenter double-blind placebo-controlled randomized phase 3 trial (December 25, 2021, to June 30, 2023, in South Korea) recruited patients with acute ischemic stroke who met the following criteria: National Institutes of Health Stroke Scale score greater than or equal to 8, Alberta Stroke Program Early Computed Tomography score greater than or equal to 4, and endovascular thrombectomy within 12 hours after stroke onset. Intervention Patients were assigned in a 1:1 ratio to receive intravenous infusions of nelonemdaz twice a day for 5 days or a matching placebo. Main Outcomes and MeasuresThe primary end point was a favorable shift in the modified Rankin scale (mRS) 12 weeks after stroke onset. The secondary end points included various composites of the mRS at 5 and 12 weeks, symptomatic intracranial hemorrhage, and infarct volume. Both intention-to-treat and per-protocol analyses were conducted. Results A total of 496 patients were enrolled across 24 Korean stroke centers, of whom 39 dropped out (254 men [55.6%]; mean [SD] age, 72.9 [12.1] years). Baseline characteristics of study participants did not significantly differ. For the primary end point, the distribution of the mRS scores at 12 weeks did not significantly differ between the nelonemdaz and placebo groups (common odds ratio, 0.95; 95% CI, 0.69-1.31). For the secondary end points, a median of mRS at 5 weeks (3 vs 3) and mRS 0 at 12 weeks (18.1% vs 18.2%) did not differ substantially between groups. The occurrence of symptomatic intracranial hemorrhage (2.7% vs 0.9%) and infarct volume within 24 hours of the last trial drug infusion (42 vs 38 mL) did not differ significantly between groups. No serious adverse events were reported regarding the trial drug and placebo. Conclusions and Relevance In this randomized clinical trial, nelonemdaz did not meet the primary efficacy end point compared with placebo.

○ ○ Article ⓘ NMAP-Net: Deep-Learning-Aided Near-Field Multibeamforming Design and Antenna Position Optimization for XL-MIMO Communications ⓘ Extremely large-scale multiple-input-multiple-output (XL-MIMO) is a candidate technology for 6G wireless networks and massive Internet of Things (IoT) communications. In this article, we consider an XL-MIMO system operating in the near-field communication range, where a base station equipped with multiple movable (i.e., adjustable-position) antennas serves multiple desired users in the presence of multiple undesired users. In this system, we investigate a new joint problem of multibeamforming design and antenna position optimization to maximize the minimum beamforming gain for the desired users with a constraint on the maximum interference leakage to the undesired users. To effectively and intelligently solve this challenging nonconvex problem, we propose a novel DL model, called NMAP-Net, which is composed of three main learnable modules, namely, DL blocks I-III, for feature extraction, antenna position optimization, and multibeamforming design, respectively. A novel training strategy for the proposed NMAP-Net is also devised in an elegant manner using a customized loss function, called adaptive loss function, to maximize the minimum beamforming gain while adaptively suppressing the maximum interference leakage. Furthermore, an effective inference mechanism for the proposed NMAP-Net is developed based on a Gaussian randomization technique to ensure the feasibility of the predicted solution. Extensive simulation results substantiate that the proposed NMAP-Net performs markedly better and more effective than the existing techniques while achieving almost the same performance as its upper limit. ⓘ Kang, Jae-Mo ⓘ Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea ⓘ ⓘ 56024930400 ⓘ jmkang@knu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 12 11 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 0 2025-05-07 ⓘ 0 0 Antennas; Antenna arrays; Array signal processing; Vectors; Optimization; Training; Transmitting antennas; Interference; Convolution; 6G mobile communication; 6G; deep learning (DL); extremely large-scale multiple-input-multiple-output (XL-MIMO); fluid antenna; Internet of Things (IoT); movable antenna; multibeamforming; near-field communication; reconfigurable antenna ⓘ MASSIVE MIMO ⓘ 6G; deep learning (DL); extremely large-scale multiple-input-multiple-output (XL-MIMO); fluid antenna; Internet of Things (IoT); movable antenna; multibeamforming; near-field communication; reconfigurable antenna ⓘ 4G mobile communication systems; 5G mobile communication systems; Beam forming networks; Benchmarking; Feedback control; Gaussian beams; Image segmentation; Linear programming; Nonlinear programming; Time difference of arrival; Trellis codes; 6g; Deep learning; Extremely large-scale multiple-input multiple-output (XL-MIMO); Fluid antenna; Internet-of-thing; Large-scales; Movable antenna; Multi-Beamforming; Multiple inputs; Multiple outputs; Near-field communication; Reconfigurable antenna; Beamforming ⓘ English 2025 2025-06-01 10.1109/jiot.2025.3555290 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Non-Data-Aided SNR Estimation for Molecular Communication Systems in Internet of Bio-Nano Things ⓘ This article proposes a nondata-aided (NDA) signal-to-noise ratio (SNR) estimation method for molecular diffusive communication channels. In contrast to previous data-aided (DA) approaches, which require a known data sequence to be shared between transmitter and receiver nanomachines, the proposed NDA method eliminates the need for prior knowledge of data symbols for the estimation process. The absence of a training sequence significantly reduces resource costs by minimizing the number of molecules required for information transmission. The expectation-maximization (EM) algorithm was used to iteratively find the maximum-likelihood (ML) estimates. The proposed method is particularly advantageous in scenarios in which accessing known data sequences is not possible, thereby ensuring robust communication in the Internet of Bio-Nano Things. By employing the ML estimates obtained through the EM algorithm, the probabilities associated with the transmission of data symbols were derived, and the bit error probabilities were obtained to assess the system performance. The numerical results validated the effectiveness of the proposed NDA SNR estimator in accurately estimating SNR over a diverse range of conditions. The proposed NDA estimator demonstrated resilience by maintaining a low bit error probability. ⓘ Yadav, Akarsh; Kumar, Ajit; Shitiri, Ethungshan; Kumar, Sudhir; Cho, Ho-Shin ⓘ Purdue Univ, Elmore Family Sch Elect & Comp Engn, W Lafayette, IN 47907 USA; Indian Inst Technol Patna, Dept Elect Engn, Bihar 801106, India; Univ Politecn Cataluna, Dept Comp Architecture, Barcelona 08034, Spain; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea ⓘ Shitiri, Ph.D., Ethungshan/Z-5918-2019 ⓘ 58122431700; 57488973800; 57190818428; 57209547997; 35316924900 ⓘ yadav111@purdue.edu; ajit_1921ee12@iitp.ac.in; ethungshan.shitiri@upc.edu; sudhir@iitp.ac.in; hscho@ee.knu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 12 1 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 0 2025-05-07 ⓘ 0 0 Signal to noise ratio; Symbols; Maximum likelihood estimation; Training; Molecular communication; Internet of Things; Nanoscale devices; expectation-maximization (EM); molecular communication (MC); nondata-aided (NDA); signal-to-noise ratio (SNR) ⓘ RECEIVER DESIGN; SYNCHRONIZATION ⓘ Expectation–maximization (EM); molecular communication (MC); nondata-aided (NDA); signal-to-noise ratio (SNR) ⓘ Channel estimation; Data communication systems; Nanoclay; Risk assessment; Data sequences; Data symbols; Expectation Maximization; Expectations maximization algorithms; Maximum-likelihood estimate; Molecular communication; Noise ratio; Non-data-aided; Signal to noise; Signalto- noise ratio estimations; Expectation maximization algorithm ⓘ English 2025 2025-01-01 10.1109/jiot.2024.3465495 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ PLAKA-MD: PUF-Based Lightweight Authentication and Key Agreement Scheme for Medical Devices in IoHT ⓘ Internet of Health Things (IoHT) integrates medical services and Internet of Things (IoT) to improve the accessibility of healthcare and accuracy of diagnosis. In IoHT environments, the transmission of sensitive data, such as patient medical records, physical characteristics, and genetic information, necessitates robust security mechanisms to protect privacy and ensure the integrity of real-time communication. Moreover, it is essential for healthcare professionals to have seamless access to patient data for accurate diagnoses. To address these demands, a lightweight and secure authentication protocol is critical for IoHT environments. Although some authentication protocols have been recently proposed in IoHT, they are susceptible to user insiders, privileged insiders, stolen verifiers, ephemeral key leakage, sensor insiders, physical attacks, and lack traceability. To overcome these vulnerabilities, we propose a mutual authentication protocol for IoHT environments. We design the proposed protocol as a lightweight using only hash functions and exclusive-OR operators. Furthermore, we utilized biometric information, physical unclonable functions (PUFs), and fuzzy extractors to strengthen security for both users and sensors. We validate the security robustness of the proposed protocol through formal analyses, including Automated Validation of Internet Security Protocols and Applications (AVISPAs), the Real-or-Random (RoR) model, and Burrows-Abadi-Needham (BAN) logic. Additionally, we evaluate the performance of the protocol by measuring the execution time of cryptographic primitives and comparing the computational and communication overheads with existing protocols. Results demonstrate that our protocol provides the most various kinds of security and functional features while maintaining similar efficiency than competing schemes. ⓘ Lee, Changui; Oh, Mingyu; Kwon, Deokkyu; Park, Youngho; Park, Yohan ⓘ Keimyung Univ, Sch Comp Engn, Daegu 42601, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea ⓘ ⓘ 59664561800; 59664157500; 57221739597; 56962990300; 55660095600 ⓘ rhljh201@naver.com; alsrb4719@gmail.com; kdk145@knu.ac.kr; parkyh@knu.ac.kr; yhpark@kmu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 12 12 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 0 2025-05-07 ⓘ 1 1 Authentication; fuzzy-extractor; fuzzy-extractor; Internet of Health Things (IoHT); Internet of Health Things (IoHT); key agreement; key agreement; physical unclonable function; physical unclonable function ⓘ USER AUTHENTICATION; EXCHANGE; EFFICIENT; PROTOCOL ⓘ Authentication; fuzzy-extractor; Internet of Health Things (IoHT); key agreement; physical unclonable function ⓘ Diagnosis; Electronic health record; Hospital data processing; Information leakage; Network security; Privacy by design; Steganography; Authentication and key agreements; Authentication protocols; Fuzzy extractors; Internet of health thing; Key agreement; Key agreement scheme; Medical Devices; Medical record; Medical services; Physical characteristics; Authentication ⓘ English 2025 2025-06-15 10.1109/jiot.2025.3543488 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Shear strength of cemented sand in unconfined compression and direct shear tests ⓘ Cemented sand, composed of sand and cement, is widely used in geotechnical engineering due to its high strength and stability. While the triaxial compression test (TCT) is a standard method for evaluating shear strength, it can be time-consuming and costly. This study proposes a simplified and cost-effective approach by integrating unconfined compression testing (UCT) with camera vision technology to estimate both compressive and shear strength parameters. Cemented sand samples with 10% cement content were tested using UCT and direct shear tests (DST). A novel camera-based technique was used to measure the failure plane angle in UCT, enabling the estimation of internal friction angle and cohesion. The results show that compressive strength and stiffness are highly sensitive to the void ratio, while internal friction angle remains relatively stable. Cohesion values obtained from UCT closely match those from TCT, confirming the reliability of the proposed method. The integration of camera vision with UCT allows for a more efficient and comprehensive evaluation of material behavior. The method has been validated through comparisons with TCT, DST, and previous studies, demonstrating its accuracy, repeatability, and practical applicability. It holds strong potential for broader use in testing various geomaterials such as soil, cemented sand, and concrete. ⓘ Park, Sung-Sik; Woo, Seung-Wook; Nguyen, Nhut-Nhut ⓘ Kyungpook Natl Univ, Dept Civil Engn, 80 Daehak Ro, Daegu 41566, South Korea ⓘ ⓘ 36241850300; 57212917862; 57211211964 ⓘ sungpark@knu.ac.kr; geowsw@knu.ac.kr; nguyennhutnhut@hcmut.edu.vn; ⓘ CONSTRUCTION AND BUILDING MATERIALS ⓘ CONSTR BUILD MATER ⓘ 0950-0618 1879-0526 489 SCIE CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 8 4.1 N/A ⓘ 0 0 Cemented sand; Angle of failure plane; Unconfined compressive strength; Shear strength, Camera vision, Crack angle ⓘ MECHANICAL-BEHAVIOR; LOADING RATE ⓘ Angle of failure plane; Cemented sand; Shear strength, Camera vision, Crack angle; Unconfined compressive strength ⓘ Adhesion; Cameras; Cements; Compression testing; Cost benefit analysis; Cost effectiveness; Geotechnical engineering; Integration testing; Sand; Shear strength; Soil testing; Angle of failure plane; Camera vision; Cemented sands; Crack angles; Direct shear test; Failure plane; Shear strength, camera vision, crack angle; Shears strength; Unconfined compression; Unconfined compressive strength; Compressive strength ⓘ English 2025 2025-08-29 10.1016/j.conbuildmat.2025.142187 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Timber-concrete composite slab using notched connections and nails in plywood units: Experimental investigation and γ-method validation ⓘ This study investigated a novel timber-concrete composite (TCC) slab system utilizing notched connections and nails in plywood units. The TCC slab system uses multiple plywood units with grooves, which are connected to timber laminae using common nails. It was developed to address the limitations of existing TCC slabs, where the use of existing mass timber products and conventional notched connections reduces their manufacturing efficiency. The TCC slab design has a hollow-core configuration which can accommodate electrical and telecommunication wiring systems to enhance the aesthetics of the timber ceiling design. The research aims to validate the gamma-method for the structural design of the TCC system. The gamma-method estimation and experimental investigation of bending performance were conducted in three different configurations to increase the reliability of validation. Compared to the results of four-point bending tests, the analytical results showed good agreement while predicting accurate failure modes, with differences of up to 4.73 %, 7.53 %, and 5.22 % for the effective bending stiffness, load-bearing capacity, and composite efficiency, respectively. The minor differences and accurate prediction of failure modes validated the applicability of the gamma-method for predicting the structural performance of the novel TCC system. ⓘ Ahn, Kyung-Sun; Oh, Jaewon; Kim, Jiyong; Kim, Min-Jeong; Lee, Gwang-Ryul; Pang, Sung-Jun; Kim, Chul-Ki; Hwang, Sung-Wook; Bang, Junsik; Yeo, Hwanmyeong; Kwak, Hyo Won; Oh, Jung-Kwon ⓘ Seoul Natl Univ, Dept Agr Forestry & Bioresources, Seoul, South Korea; Univ British Columbia, Dept Wood Sci, Vancouver, BC, Canada; Chonnam Natl Univ, Dept Wood Sci & Engn, Gwangju, South Korea; Natl Inst Forest Sci, Wood Engn Div, Seoul, South Korea; Kyungpook Natl Univ, Human Resource Dev Ctr Big Data Based Glocal Fores, Daegu, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, Seoul, South Korea ⓘ Kwak, Hyo/AAG-9875-2019; Chulki, Kim/AFZ-8924-2022 ⓘ 57216916071; 57998384800; 57214339052; 58577631000; 58577392100; 42361604600; 55509241400; 57139273300; 57222197530; 59900149900; 57220806677; 55462886000 ⓘ jungoh@snu.ac.kr; ⓘ CONSTRUCTION AND BUILDING MATERIALS ⓘ CONSTR BUILD MATER ⓘ 0950-0618 1879-0526 487 SCIE CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 8 4.1 N/A ⓘ 0 0 Timber-concrete composite; Notched connection; Nail connection; Plywood unit; Composite structure; gamma-method validation; Hollow-core slab ⓘ SHEAR; BEHAVIOR; FLOORS ⓘ Composite structure; Hollow-core slab; Nail connection; Notched connection; Plywood unit; Timber-concrete composite; γ-method validation ⓘ Lumber; Plywood; Structural analysis; Structural dynamics; Composites structures; Experimental investigations; Hollow-core slabs; Method validations; Nail connections; Notched connection; Plywood unit; Timber-concrete composite slabs; Timber-concrete composites; Γ-method validation; Concrete slabs ⓘ English 2025 2025-08-15 10.1016/j.conbuildmat.2025.141860 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Uncrewed Aerial Vehicles Empowering Secure Authentication in Cognitive IoMT for Transformative Knowledge Discovery in Data ⓘ The paradigm shift toward digital transformation is increasingly advancing toward cognitive decision discovery, particularly within the healthcare domain, where it has emerged as a critical area of research. Numerous researchers are actively contributing to this field. However, due to the sensitive nature of healthcare data, ensuring robust security within the cognitive decision-making process is paramount for Internet of Medical Things (IoMT). To address this concern, the present study proposes a comprehensive privacy-preserving authentication scheme associating aerial computing and knowledge discovery. This scheme leverages an elliptic curve-based cryptosystem to establish the authentication protocol and incorporates blockchain technology to ensure data storage security. Furthermore, the scheme facilitates secure knowledge discovery in data (KDD) within cognitive decision-making frameworks. The proposed authentication mechanism is evaluated across communication, computational efficiency, and security parameters to validate its functionality and robustness as well as to formally verify the developed scheme Scyther tool verification is done by authors. Additionally, to demonstrate the necessity and effectiveness of the proposed scheme, the authors conducted a KDD experiment using both a securely authenticated dataset and an insecure, compromised dataset. The results of these experiments are presented and thoroughly analyzed in the article. ⓘ Pandey, Abhishek Kumar; Das, Ashok Kumar; Wazid, Mohammad; Kaur, Kuljeet; Park, Youngho; Hassan, Mohammad Mehedi ⓘ Int Inst Informat Technol, Ctr Secur Theory & Algorithm Res, Hyderabad 500032, India; Korea Univ, Coll Informat, Dept Comp Sci & Engn, Seoul 02841, South Korea; Graph Era Deemed be Univ, Dept Comp Sci Engn, Dehra Dun 248002, India; Ecole Technol Super, Elect Engn Dept, Montreal, PQ H3C 1K3, Canada; Chitkara Univ, Inst Engn & Technol, Ctr Res Impact & Outcome, Rajpura 140401, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; King Saud Univ, Coll Comp & Informat Sci, Dept Informat Syst, Riyadh 11543, Saudi Arabia ⓘ ; Das, Ashok Kumar/U-2790-2019; Hassan, Mohammad Mehedi/LGZ-9005-2024; Kaur, Kuljeet/R-1091-2018; WAZID, MOHAMMAD/X-4211-2018; Pandey, Abhishek/AAN-2756-2020 ⓘ 57215585159; 55450732800; 55480987400; 56524077100; 56962990300; 57201949986 ⓘ abhishek.pandey@research.iiit.ac.in; iitkgp.akdas@gmail.com; wazidkec2005@gmail.com; kuljeet.kaur@ieee.org; parkyh@knu.ac.kr; mmhassan@ksu.edu.sa; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 12 9 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 N/A ⓘ 1 1 Aerial computing; authentication; blockchain; data analytics; Internet of Medical Things (IoMT); scyther tool; security; Aerial computing; authentication; blockchain; data analytics; Internet of Medical Things (IoMT); scyther tool; security ⓘ KEY; PROTOCOL; INTERNET ⓘ Aerial computing; authentication; blockchain; data analytics; Internet of Medical Things (IoMT); scyther tool; security ⓘ Anonymity; Authentication; Data Analytics; Network security; Privacy by design; Aerial computing; Block-chain; Cognitive decision makings; Data analytics; Internet of medical thing; Knowledge discovery in data; Scyther tools; Secure authentications; Security; Uncrewed aerial vehicles; Sensitive data ⓘ English 2025 2025-05-01 10.1109/jiot.2025.3549720 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Acute and neurological toxicities of endosulfan I, endosulfan sulfate, endosulfan diol, and endosulfan ether in zebrafish (Danio rerio) embryos: Developmental effects on heart and brain formation ⓘ Endosulfan (ES) is classified as a persistent organic pollutant (POP), and its use has been banned in the agricultural sectors of most countries. It is metabolized into several compounds, among which ES sulfate is frequently detected in the environment. In this study, the acute toxicities of α-ES, ES sulfate, ES diol, and ES ether were evaluated in zebrafish (Danio rerio) embryos. No acute toxicity was observed at tested concentrations ranging from 0.125 to 1.0 mg/L. However, severe morphological deformities were detected in embryos treated with α-ES and ES sulfate. Whole body length was significantly reduced in two chemicals-treated embryos. Electroencephalogram analysis revealed a marked increase in ictal-like events in embryos exposed to α-ES and ES sulfate. α-ES caused abnormal development of the midbrain and hindbrain at 72 h post-fertilization (hpf), while ES sulfate induced hindbrain malformation at the same stage. Abnormal atrial formation, along with cardiac dysfunction, was observed in embryos treated with α-ES and ES sulfate. These cardiac abnormalities were associated with the downregulation of amhc and gata4, genes involved in atrial and cardiac development. A significant increase in apoptotic cells was observed in the pericardial regions of embryos exposed to α-ES and ES sulfate. Collectively, these findings suggest that the transformation of ES into ES sulfate warrants concern due to its retention of ES toxicity and environmental persistence. © 2025 Elsevier Inc. ⓘ Kim, Ranyun; Kim, Chaeeun; Son, Junhee; Kim, Donghyeon; Park, Junyeong; Yang, Jinuk; You, Yongha; Lee, Sung-Eun ⓘ Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; Department of Integrative Biology, Kyungpook National University, Daegu, 41566, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; Department of Integrative Biology, Kyungpook National University, Daegu, 41566, South Korea; Department of Integrative Biology, Kyungpook National University, Daegu, 41566, South Korea; Department of Integrative Biology, Kyungpook National University, Daegu, 41566, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea, Department of Integrative Biology, Kyungpook National University, Daegu, 41566, South Korea ⓘ ⓘ 59960352500; 57200245142; 59903534000; 57780824900; 59960184500; 59960352600; 59959704100; 59896108900 ⓘ selpest@knu.ac.kr; ⓘ Environmental Research ⓘ ENVIRON RES ⓘ 0013-9351 1096-0953 284 SCIE ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 7.7 4.2 ⓘ 0 ⓘ ⓘ Apoptotic cells; Brain and cardiac abnormalities; Endosulfan; Endosulfan sulfate; Ictal-like events; Zebrafish embryos ⓘ Agriculture; Brain; Cardiology; Electroencephalography; Invertebrates; Sulfur compounds; Toxicity; Acute toxicity; Apoptotic cells; Brain and cardiac abnormality; Endosulfan diol; Endosulfan sulfate; Endosulfans; Exposed to; Ictal-like event; Zebrafish danio rerio; Zebrafish embryos; brain; cardiovascular disease; cell; cyprinid; embryo; endosulfan; gene expression; neurology; persistent organic pollutant; toxicity; Heart ⓘ English Final 2025 10.1016/j.envres.2025.122235 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Applicability of plant-clay mineral composite for rapid algae removal from eutrophic freshwaters at the laboratory and field scales ⓘ The global issue of water source eutrophication is exacerbated by increasing industrialization and urbanization, posing significant challenges for clean water management. Although strategies such as nutrient management and biomanipulation are employed, these methods often take longer to demonstrate effectiveness and indirectly work on algal blooms. This has led to the evaluation of eco-friendly technologies such as plant-mineral composites (PMCs) for faster and targeted control of algal proliferation and organic pollution. This study assessed the suitability of PMCs for rapid improvement of eutrophic water quality (focusing on algal control) and optimized their application methods at laboratory and field scales. Laboratory experiments were conducted to identify the critical factors influencing removal activity (RA), considering variables such as water temperature and light intensity. Field trials in reservoirs and a water treatment plant (WTP) explored the controlling factors influencing the RAs for various pollutants. Optimal conditions for maximizing PMC efficacy were determined using response surface methodology (RSM) and generalized linear models. RSM highlighted water temperature as a key factor influencing chlorophyll a RA in a unimodal manner, while demonstrating PMC's effectiveness across varying concentrations, depths, and pH levels. Results from the WTP emphasized the high PMC efficacy in humic matter-rich environments, and those from reservoirs consistently demonstrated PMC's effectiveness regardless of ambient water quality factors such as nutrient and conductivity levels. Comparative analyses indicated distinct PMC impact on algae-associated parameters, emphasizing its potential as an innovative solution for utilizing plant allelopathy and mineral adsorption for efficient algal bloom control and water quality enhancement. ⓘ Han, Byeong-Hun; Kim, Hyo Gyeom; Kim, Young-Hyo; Cho, In-Hwan; Kim, Ha-Kyung; Hong, Sungwon; Kim, Baik-Ho ⓘ Hanyang Univ, Dept Environm Sci, Seoul 04763, South Korea; Korea Univ, Future & Fus Lab Architectural Civil & Environm En, Seoul 02841, South Korea; Minist Environm, Youngsan River Environm Management Off, Gwangju 61945, South Korea; Migang ENC Co Ltd, Gyeonggi 14057, South Korea; Natl Inst Environm Res, Inchon 22689, South Korea; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Hanyang Univ, Dept Life Sci, Seoul 04763, South Korea; Hanyang Univ, Res Inst Nat Sci, Seoul 04763, South Korea ⓘ Kim, Baik-Ho/D-9356-2011 ⓘ 59447206000; 57207108347; 57196050613; 57210360617; 56382720400; 56431586600; 7501563499 ⓘ tigerk@hanyang.ac.kr; ⓘ ENVIRONMENTAL RESEARCH ⓘ ENVIRON RES ⓘ 0013-9351 1096-0953 266 SCIE ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 7.7 4.2 0 2025-05-07 ⓘ 0 0 Allelopathic activity; Cyanobacteria; Blooming; Coagulation; Water treatment; PMC ⓘ MICROCYSTIS-AERUGINOSA; CYANOBACTERIAL BLOOMS; BIOMANIPULATION; FLOCCULATION; ECOSYSTEMS; HERBICIDES; CLIMATE ⓘ Allelopathic activity; Blooming; Coagulation; Cyanobacteria; PMC; Water treatment ⓘ Chlorophyll A; Eutrophication; Fresh Water; Water Purification; Blooms (metal); Clay minerals; Water pollution control; chlorophyll a; fresh water; mineral; chlorophyll a; fresh water; Algae removal; Algal blooms; Allelopathic activity; Blooming; Cyanobacterium; Plant–mineral composite; Removal activity; Response-surface methodology; Treatment plants; Water temperatures; adsorption; algal bloom; allelopathy; biomanipulation; chlorophyll a; clay mineral; response surface methodology; water quality; water treatment plant; alga; Article; concentration (parameter); conductance; environmental factor; eutrophy (environment); field experiment; humic substance; Korea; laboratory; light intensity; nonhuman; nutrient; pH; physical chemistry; plant; regression analysis; response surface method; statistical model; water depth; water pollutant; water quality; water temperature; water treatment; chemistry; eutrophication; procedures; water management; Eutrophication ⓘ English 2025 2025-02-01 10.1016/j.envres.2024.120468 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Bifunctional hierarchical WO3 nanorods@Br-doped g-C3N4 Z-scheme heterojunctions for efficient tetracycline photodegradation: Optimization of key parameters, toxicological assessment, and electrocatalytic hydrogen evolution reaction ⓘ In this study, graphitic carbon nitride (CN) and tungsten trioxide (WO3) were successfully incorporated into bromine (Br)-doped graphitic carbon nitride (BCN) using an in-situ hydrothermal method. The photocatalytic efficiency of the resulting WO3/Br-doped CN (WBCN) composites for the removal of tetracycline (TC) antibiotics under sunlight irradiation was evaluated. The mass ratio of WO3 to Br-doped CN (BCN) significantly influenced TC adsorption and photocatalytic degradation, with an optimal ratio of 9:1. The synthesized catalyst exhibited exceptional performance, achieving 98% TC detoxification under sunlight, attributed to enhanced light absorption, efficient charge separation, and reduced electron-hole (e_/h+) recombination facilitated by BCN doping. Trapping experiments and ESR analysis identified center dot O 2 _ and center dot OH as the primary reactive species in TC decomposition, with h+ radicals playing a secondary role. Reusability tests further confirmed the high stability of the photocatalyst. The Z-scheme charge transfer mechanism was elucidated, highlighting the crucial role of Br doping in enhancing synergistic interactions between WO3 and CN. Additionally, the nickel foam (NF) electrode supported by the WBCN-2 composite demonstrated remarkable electrocatalytic activity for hydrogen evolution, achieving a minimum overpotential of 99 mV and a Tafel slope of 108 mV/dec at a current density of 10 mA/ cm2. The WBCN-2@NF composite catalyst also achieved excellent performance, with a low cell voltage of 1.77 V at 10 mA/cm2. Chronopotentiometry (CP) tests revealed remarkable long-term stability, with minimal current loss over 15 h of continuous operation. Overall, the WBCN composite exhibits excellent photocatalytic and electrocatalytic performance, making it a promising candidate for practical environmental remediation and sustainable energy production. ⓘ Kumaravel, Sakthivel; Erusappan, Elangovan; Vignesh, Shanmugam; Chicardi, E.; Periyasami, Govindasami; Devarayapalli, Kamakshaiah Charyulu; Kim, Bolam; Oh, Tae Hwan; Lee, Dae Sung ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Inst Bioinformat, Chennai 602105, Tamil Nadu, India; Yeungnam Univ, Sch Chem Engn, Gyongsan, South Korea; Univ Seville, ETS Ingn, Dept Ingn & Ciencia Mat & Transporte, Avda Camino Descubrimientos S-N, Seville 41092, Spain; King Saud Univ, Coll Sci, Dept Chem, POB 2455, Riyadh 11451, Saudi Arabia ⓘ KUMARAVEL, SAKTHIVEL/KBC-0974-2024; Govindasami, Periyasami/K-9962-2016; Erusappan, Elangovan/GON-8284-2022 ⓘ 57212580936; 57195219856; 59315621100; 46461062300; 15059331100; 15069351300; 57208922438; 57213539906; 55568524907 ⓘ taehwanoh@ynu.ac.kr; daesung@knu.ac.kr; ⓘ ENVIRONMENTAL RESEARCH ⓘ ENVIRON RES ⓘ 0013-9351 1096-0953 268 SCIE ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 7.7 4.2 0 2025-05-07 ⓘ 0 0 Photocatalyst; Degradation; Tetracycline; Hydrogen evolution reaction ⓘ ENHANCED PHOTOCATALYTIC PERFORMANCE; FACILE SYNTHESIS; CONSTRUCTION; DEGRADATION; WATER; NANOPARTICLES; COMPOSITES; OXIDE; HETEROSTRUCTURES; CONTAMINANTS ⓘ Degradation; Hydrogen evolution reaction; Photocatalyst; Tetracycline; WO<sub>3</sub>/Br-g-C<sub>3</sub>N<sub>4</sub> ⓘ Anti-Bacterial Agents; Catalysis; Graphite; Hydrogen; Nanotubes; Nitriles; Nitrogen Compounds; Oxides; Photolysis; Tetracycline; Tungsten; Water Pollutants, Chemical; Bioremediation; Detoxification; Electric discharges; Electron spin resonance spectroscopy; Emission control; Escherichia coli; Graphitic Carbon Nitride; Infrared absorption; Noise pollution; Photocatalytic activity; Photodegradation; Photolysis; Reusability; Semiconductor doping; Soil pollution; Thermal pollution; bromine; chemical compound; graphitic carbon nitride; nanorod; tetracycline; tungsten derivative; tungsten trioxide; unclassified drug; antiinfective agent; cyanogen; graphite; graphitic carbon nitride; hydrogen; nanotube; nitrile; nitrogen derivative; oxide; tetracycline; tungsten; tungsten oxide; Bi-functional; Doped carbons; Graphitic carbon nitrides; Hydrogen evolution reactions; Nickel foam; Optimisations; Performance; Photo degradation; Tetracycline; WO3/bromine-g-C3N4; antibiotics; bioremediation; bromine; catalyst; composite; free radical; hydrogen; irradiation; photodegradation; toxicology; Article; Brunauer Emmett Teller method; chronopotentiometry; controlled study; detoxification; electrocatalysis; energy dispersive X ray spectroscopy; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; high resolution transmission electron microscopy; hydrogen evolution reaction; light absorption; linear sweep voltammetry; pH; photocatalysis; photodegradation; pore size; pore volume; sunlight; toxicology; X ray diffraction; X ray photoemission spectroscopy; zeta potential; catalysis; chemistry; photolysis; water pollutant; Nanorods ⓘ English 2025 2025-03-01 10.1016/j.envres.2025.120793 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Comparison of the toxicity and potential ecological risks of various pesticides for nurses of honey bee (Apis mellifera. L) ⓘ The honey bee (Apis mellifera. L) is an important pollinator worldwide, but it is facing significant population declines due to the influence of various factors, particularly the use of pesticides. Forager bees come into contact with pesticides during their foraging activity, while nurse bees are exposed to pesticides within the hive when they consume contaminated food sources. Based on established pesticide exposure routes, the present study assessed the oral toxicity and ecotoxic risks of 13 pesticides, including two organophosphates [coumaphos (COU) and fenitrothion (FEN)], two pyrethroids [ti-fluvalinate (tiFLU) and cypermethrin (CYP)], four neonicotinoids [acetamiprid (ACE), imidacloprid (IMI), thiamethoxam (THIA), and flupyradifurone (FLU)], two carbamates [carbaryl (CAR) and carbofuran (CAB)], two avermectins [abamectin (ABA) and ivermectin (IVE)], and one phenyl pyrazole, fipronil (FIP) for nurse bees using the median lethal dose (LD50) and hazard quotients (HQs), respectively. Based on LD50 data from bioassays and previous reports, ranking pesticides by their toxicity for nurse bees resulted in the following order: FIP = THIA > ABA > IVE > CAB > IMI = FEN > CAR > CYP > FLU > ACE > COU = tiFLU. The HQs were calculated using the LD50 and arithmetic field-detected concentration for each pesticide in bee bread and honey based on the previous studies. The HQ results indicated THIA had the highest potential risk for honey bees, followed by FIP, CAR, FLU, CYP, CAB, FEN, IMI, COU, tiFLU, and ACE. Quadrant-based analysis subsequently revealed that high LD50 values were not necessarily associated with high HQs for nurse honey bees. These findings suggest that differences in the residue concentration of the pesticides due to differences in their chemical properties and usages can influence their actual risk in natural systems, which is not in direct accordance with their toxicity. This study thus highlights the importance of assessing the effect of agrochemicals on honey bees in an ecological context. ⓘ You, Euijin; Cha, Jooheon; Kim, Heejin; Kim, Young Ho ⓘ Kyungpook Natl Univ, Dept Ecol Sci, Sangju, South Korea; Kyungpook Natl Univ, Dept Vector Entomol, Sangju, South Korea ⓘ ⓘ 58723539100; 57965439100; 58295958700; 58516491300 ⓘ yhkim05@knu.ac.kr; ⓘ ENVIRONMENTAL CHEMISTRY AND ECOTOXICOLOGY ⓘ ENVIRON CHEM ECOTOX ⓘ 2590-1826 7 ESCI ENVIRONMENTAL SCIENCES;TOXICOLOGY ⓘ 2024 8.2 4.2 0 2025-05-07 ⓘ 0 0 Pesticide; Median lethal dose; Hazard quotient; Eco-toxicity; Apis mellifera L. ⓘ NEONICOTINOID INSECTICIDES; CONTAMINATED POLLEN; CHRONIC EXPOSURE; COLONY COLLAPSE; HYMENOPTERA; RESIDUES; FIPRONIL; LOSSES; APIDAE; FLUVALINATE ⓘ Apis mellifera L.; Eco-toxicity; Hazard quotient; Median lethal dose; Pesticide ⓘ Biohazards; Insecticides; Toxicity; Apis mellifera; Apis mellifera L; Cypermethrins; Ecotoxicity; Fenitrothion; Hazard quotients; Honey bee; Imidacloprids; Median lethal dose; Thiamethoxam; agrochemical; ecotoxicology; foraging behavior; honeybee; pesticide; pollution exposure; population decline; risk assessment; Bioassay ⓘ English 2025 2025 10.1016/j.enceco.2025.04.008 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Efficient Hybrid Training Method for Neuromorphic Hardware Using Analog Nonvolatile Memory ⓘ Neuromorphic hardware using nonvolatile analog synaptic devices provides promising advantages of reducing energy and time consumption for performing large-scale vector-matrix multiplication (VMM) operations. However, the reported training methods for neuromorphic hardware have appreciably shown reduced accuracy due to the nonideal nature of analog devices, and use conductance tuning protocols that require substantial cost for training. Here, we propose a novel hybrid training method that efficiently trains the neuromorphic hardware using nonvolatile analog memory cells, and experimentally demonstrate the high performance of the method using the fabricated hardware. Our training method does not rely on the conductance tuning protocol to reflect weight updates to analog synaptic devices, which significantly reduces online training costs. When the proposed method is applied, the accuracy of the hardware-based neural network approaches to that of the software-based neural network after only one-epoch training, even if the fabricated synaptic array is trained for only the first synaptic layer. Also, the proposed hybrid training method can be efficiently applied to low-power neuromorphic hardware, including various types of synaptic devices whose weight update characteristics are extremely nonlinear. This successful demonstration of the proposed method in the fabricated hardware shows that neuromorphic hardware using nonvolatile analog memory cells becomes a more promising platform for future artificial intelligence. ⓘ Kwon, Dongseok; Woo, Sung Yun; Hwang, Joon; Kim, Hyeongsu; Bae, Jong-Ho; Shin, Wonjun; Park, Byung-Gook; Lee, Jong-Ho ⓘ Seoul Natl Univ, Sch Elect & Comp Engn, Seoul 08826, South Korea; Seoul Natl Univ, Interuniv Semicond Res Ctr, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kookmin Univ, Sch Elect Engn, Seoul 02707, South Korea; Minist Sci & ICT, Sejong 30109, South Korea ⓘ Lee, Jingyu/AAV-8920-2020; Bae, Jong-Ho/V-5237-2019; Kwon, Dongseok/JDC-8584-2023 ⓘ 57203288190; 57201527826; 57224668810; 57204692859; 55339347700; 57210823123; 57221622173 ⓘ jhl@snu.ac.kr; ⓘ IEEE TRANSACTIONS ON NEURAL NETWORKS AND LEARNING SYSTEMS ⓘ IEEE T NEUR NET LEAR ⓘ 2162-237X 2162-2388 36 1 SCIE COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, THEORY & METHODS;ENGINEERING, ELECTRICAL & ELECTRONIC ⓘ 2024 8.9 4.2 2.95 2025-05-07 ⓘ 2 1 Hardware; Training; Neuromorphics; Tuning; Nonvolatile memory; Neural networks; Protocols; Hybrid training; neuromorphic hardware; neuromorphic system; online training ⓘ NEURAL-NETWORKS; NAND FLASH; TFT-TYPE; ARCHITECTURE; RECOGNITION; SYNAPSES; MODELS; ARRAY ⓘ Hybrid training; neuromorphic hardware; neuromorphic system; online training ⓘ Cost reduction; Memory architecture; Neural networks; Semiconductor storage; Hardware; Hybrid training; Neural-networks; Neuromorphic; Neuromorphic hardwares; Neuromorphic systems; Non-volatile memory; Nonvolatile memory; Online training; Tuning; article; artificial intelligence; computer; conductance; controlled study; hybrid; memory; memory cell; nerve cell network; software; training; E-learning ⓘ English 2025 2025-01 10.1109/tnnls.2023.3327906 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Efficient photo-assisted activation of peroxydisulfate by a novel Z-scheme sulfur-doped C3N5/DyFeO3 heterojunction for norfloxacin degradation: Activation mechanism and DFT studies on reaction pathways ⓘ Peroxydisulfate (PDS) activation is a crucial process for wastewater treatment in complicated water matrices. However, it is frequently limited because of poor selectivity, sluggish kinetics, and short lifetime of radicals. Therefore, in this study, an efficient sulfur-doped C3N5/DyFeO3 (SCN/DyF) Z-scheme heterostructure catalyst was rationally developed using a simple wet-chemical strategy to photoactivate PDS, which can effectively degrade norfloxacin (NOR; 96.1%) in a water environment. The coupling of SCN/DyF catalyst with PDS shows favorable synergistic effect, with NOR degradation rate in the following order: SCN/DyF-1 (k = 0.0177/min) < SCN/DyF-2 (k = 0.0253/min) < SCN/DyF-3 (k = 0.0343/min) < SCN/DyF-4 (k = 0.0441/min) after 60 min of irradiation. The optimal SCN/DyF-4 achieved a higher NOR degradation under the reaction conditions of 0.6 g/L catalyst dosage, 10 mg/L NOR concentration, natural pH (6.7), and 2.0 mM PDS. The SCN/DyF heterojunction exhibited impressive PDS photoactivation performance because of its Z-scheme charge-transfer platform, accelerated redox cycle, and enhanced light absorption. Furthermore, the structural changes and chemical interactions between the main elements of the catalysts were systematically investigated. Two reaction routes for NOR degradation were identified by combining radical-trapping tests and electron spin resonance spectroscopy. Moreover, the ecotoxicity of the degraded NOR intermediates were confirmed through density functional theory calculations. This work provides an ideal platform for activating PDS systems using Z-scheme photocatalysts for real water remediation. ⓘ Saravanakumar, Karunamoorthy; Jagan, Govindan; Njaramba, Lewis Kamande; Yoon, Yeomin; Park, Chang Min ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea ⓘ Kamande, Lewis/JLL-5435-2023; Yoon, Yeomin/KDP-2253-2024; Karunamoorthy, Saravanakumar/Q-2005-2016; Park, Chang Min/CAA-8506-2022 ⓘ 57223020778; 57885044400; 57223183206; 7402126688; 57209588953 ⓘ sravanan205@gmail.com; jagan1771996@gmail.com; lewiskamande@gmail.com; yoony@ewha.ac.kr; cmpark@knu.ac.kr; ⓘ ENVIRONMENTAL RESEARCH ⓘ ENVIRON RES ⓘ 0013-9351 1096-0953 268 SCIE ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 7.7 4.2 0 2025-05-07 ⓘ 0 0 Norfloxacin; Peroxydisulfate; Z-Scheme; Photocatalyst ⓘ CARBON NITRIDE; RADICALS; KINETICS ⓘ Norfloxacin; Peroxydisulfate; Photocatalyst; Sulfur-doped C<sub>3</sub>N<sub>5</sub>; Z-Scheme ⓘ Catalysis; Density Functional Theory; Norfloxacin; Photolysis; Sulfates; Sulfur; Water Pollutants, Chemical; Activation analysis; Biodegradation; Bioremediation; Chemical activation; Doping (additives); Free radical reactions; Hydrolysis; Infrared absorption; Ligands; Photocatalysts; Photocatalytic activity; Photodegradation; Photolysis; Reaction intermediates; Reaction kinetics; Redox reactions; Spectroscopic analysis; Wastewater reclamation; Wastewater treatment; carbon; nitrogen; norfloxacin; sulfate; sulfur; sulfate; sulfur; Activation mechanisms; DFT study; Mechanism studies; Norfloxacin; Peroxydisulfate; Photo-assisted; Reaction pathways; Sulphur-doped C3N5; Z-scheme; ]+ catalyst; catalyst; concentration (composition); degradation; drug; hydroxyl radical; pollutant removal; salt; wastewater treatment; Article; catalyst; chemical interaction; chemical structure; controlled study; density functional theory; drug degradation; electron spin resonance; pH; photocatalysis; catalysis; chemistry; density functional theory; photolysis; water pollutant; Electron spin resonance spectroscopy ⓘ English 2025 2025-03-01 10.1016/j.envres.2024.120735 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Efficient visible-light-driven removal of persistent antibiotics and synthetic dyes from wastewater using an engineered 2D/2D Bi2MoO6/NiAl-LDH S-scheme heterocatalyst with enhanced interfacial contact ⓘ Highly efficient photocatalysts for degrading persistent antibiotics and synthetic dye pollutants under visible light are crucial for sustainable environmental remediation. In this study, we engineered a novel Bi2MoO6 (BMO)/NiAl-LDH (layered double hydroxide) hybrid catalyst with a unique 2D/2D heterostructure, optimized for the visible-light-driven elimination of ciprofloxacin (CPF) and hazardous synthetic dyes such as rhodamine B and methylene blue. The optimized BMO-30/LDH hybrid demonstrated exceptional photocatalytic performance, achieving nearly complete degradation of CPF and synthetic dyes with high mineralization efficiency, surpassing many previously reported state-of-the-art photocatalysts. This superior activity is primarily attributed to the formation of an S-scheme heterojunction, which enhances charge separation while maintaining strong redox potentials in both components. This mechanism enables the simultaneous generation of reactive O2 center dot- and center dot OH radicals. The hybrid's enhanced efficiency is further driven by synergistic effects, including strong visible light absorption, a large surface area, and a well-integrated 2D/2D configuration with face-to-face interfacial contact. These structural features maximize charge carrier separation, reduce recombination, and ensure robust photo- catalytic activity. Additionally, the hybrid exhibited excellent reusability, retaining over 93% of its initial activity after five cycles. This study introduces a novel approach to engineering advanced 2D/2D heterojunction photocatalysts, highlighting their potential for practical water treatment and environmental remediation applications. ⓘ Lee, Dong-Eun; Moru, Satyanarayana; Jo, Wan-Kuen; Tonda, Surendar ⓘ Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; VIT AP Univ, Sch Adv Sci, Amaravati 522237, Andhra Prades, India ⓘ Jo, Wan/AAO-5329-2020; Tonda, Surendar/AAO-3358-2020 ⓘ 59510700000; 58562229700; 7103322277; 56114866900 ⓘ wkjo@knu.ac.kr; surendar.t86@gmail.com; ⓘ ENVIRONMENTAL RESEARCH ⓘ ENVIRON RES ⓘ 0013-9351 1096-0953 267 SCIE ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 7.7 4.2 3.08 2025-05-07 ⓘ 4 6 NiAl-LDH; 2D/2D hybrid configuration; S -Scheme heterostructure; Pollutants degradation; Environmental remediation ⓘ HETEROJUNCTION; PHOTOCATALYSIS; OXIDATION; HYBRID; BIVO4 ⓘ 2D/2D hybrid configuration; Bi<sub>2</sub>MoO<sub>6</sub>; Environmental remediation; NiAl-LDH; Pollutants degradation; S-Scheme heterostructure ⓘ Anti-Bacterial Agents; Bismuth; Catalysis; Ciprofloxacin; Coloring Agents; Light; Molybdenum; Photolysis; Wastewater; Water Pollutants, Chemical; Bioremediation; Bismuth alloys; Free radical reactions; Laser beams; Photocatalysts; Photocatalytic activity; Photodegradation; Reusability; Rhodamine B; Vat dyes; Wastewater treatment; Water pollution; antibiotic agent; ciprofloxacin; dye; hydroxide; hydroxyl radical; lactate dehydrogenase; methylene blue; oxygen; rhodamine B; antiinfective agent; Bi(2)MoO(6); bismuth; coloring agent; molybdenum; 2d/2d hybrid configuration; Dye pollutants; Environmental remediation; Hybrid configurations; Interfacial contact; Nial-LDH; Pollutant degradation; S-scheme heterostructure; Synthetic dyes; Visible-light-driven; antibiotics; catalyst; dye; performance assessment; photodegradation; pollutant removal; redox conditions; separation; visible spectrum; wastewater treatment; Article; catalyst; degradation; ecosystem restoration; electric potential; genetic recombination; hybrid; light; light absorption; mineralization; nonhuman; oxidation reduction potential; pharmacology; pollutant; surface area; waste water management; wastewater; water treatment; catalysis; chemistry; photolysis; water pollutant; Redox reactions ⓘ English 2025 2025-02-15 10.1016/j.envres.2024.120699 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ HOS15 impacts DIL9 protein stability during drought stress in Arabidopsis ⓘ HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE 15 (HOS15) acts as a substrate receptor of E3 ligase complex, which plays a negative role in drought stress tolerance. However, whether and how HOS15 participates in controlling important transcriptional regulators remains largely unknown. Here, we report that HOS15 physically interacts with and tightly regulates DROUGHT-INDUCED LIKE 19 (DIL9) protein stability. Moreover, application of exogenous abscisic acid (ABA) stabilizes the interaction between DIL9 and HOS15, leading to ABA-induced proteasomal degradation of DIL9 by HOS15. Genetic analysis revealed that DIL9 functions downstream to HOS15 and that the drought tolerance of hos15-2 plants was impaired in dil9/hos15 double mutants. Notably, DIL9 is directly associated with the promoter regions of ABF transcription factors and facilitates their expression, which is pivotal in enhancing ABA-dependent drought tolerance. Collectively, these findings demonstrate that HOS15 consistently degrades DIL9 under normal condition, while stress (drought/ABA) promotes the DIL9 activity for binding to the promoter regions of ABFs and positively regulates their expression in response to dehydration. ⓘ Zareen, Shah; Ali, Akhtar; Park, Junghoon; Kang, Sang-Mo; Lee, In-Jung; Pardo, Jose M.; Yun, Dae-Jin; Xu, Zheng-Yi ⓘ Konkuk Univ, Dept Biomed Sci & Engn, Seoul 05029, South Korea; Konkuk Univ, Plant Global Stress Res Ctr, Seoul 05029, South Korea; Ctr Plant Syst Biol & Biotechnol, Dept Mol Stress Physiol, Plovdiv 4000, Bulgaria; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Univ Seville, Inst Bioquim Vegetal & Fotosintesis, CicCartuja, CSIC, Amer Vespucio 49, Seville 41092, Spain; Northeast Normal Univ, Key Lab Mol Epigenet, Minist Educ MOE, Changchun 130024, Peoples R China ⓘ ; Pardo, Jose M/B-4652-2009; Pardo, Jose/B-4652-2009; Ali, Akhtar/ABD-3928-2021; Kang, Sang-Mo/MBG-7823-2025; Lee, In-Jung/GLS-0432-2022 ⓘ 57217091915; 56293289900; 57196409153; 56189696900; 16425830900; 7201755168; 35228284000; 55598579900 ⓘ djyun@konkuk.ac.kr; xuzy100@nenu.edu.cn; ⓘ NEW PHYTOLOGIST ⓘ NEW PHYTOL ⓘ 0028-646X 1469-8137 245 6 SCIE PLANT SCIENCES ⓘ 2024 8.1 4.2 0 2025-05-07 ⓘ 2 2 ABA and drought stress; ABFs TFs; Arabidopsis; DIL9; HOS15; proteasomal degradation ⓘ TRANSCRIPTION FACTOR; ABSCISIC-ACID; GENE-EXPRESSION; PLANT-RESPONSES; TOLERANCE; DEHYDRATION; KINASES; ATDI19 ⓘ ABA and drought stress; ABFs TFs; Arabidopsis; DIL9; HOS15; proteasomal degradation ⓘ Abscisic Acid; Adaptation, Physiological; Arabidopsis; Arabidopsis Proteins; Droughts; Gene Expression Regulation, Plant; Mutation; Promoter Regions, Genetic; Proteasome Endopeptidase Complex; Protein Binding; Protein Stability; Proteolysis; Stress, Physiological; abscisic acid; Arabidopsis protein; proteasome; protein binding; abscisic acid; biodegradation; dehydration; dicotyledon; drought stress; gene expression; genetic analysis; mutation; protein; Arabidopsis; drought; drug effect; gene expression regulation; genetics; metabolism; mutation; physiological adaptation; physiological stress; physiology; promoter region; protein degradation; protein stability ⓘ English 2025 2025-03 10.1111/nph.20398 ⓘ 바로가기 바로가기 바로가기 바로가기
