| ○ | ○ | Article | Enhanced performance of Zn-modified (MnCo)1.5O4 spinel coatings: Investigating critical properties for SOFC interconnect materials | Zn x Mn 1.5-0.5x Co 1.5-0.5x O 4 (ZMCO) powders were synthesized using a solid-state method and applied to 460 FC stainless-steel interconnects via electrophoretic deposition for solid oxide fuel cell (SOFC) applications. A reduction-oxidation heat treatment at 800 degrees C was used to densify the coating while maintaining compatibility with SOFC operating temperatures. X-ray diffraction analysis confirmed the reversible phase transformation of ZMCO spinel into MnO and Co metal during reduction, followed by spinel reformation upon oxidation. EPMA results demonstrated the coating's effectiveness as a Cr diffusion barrier. The composition with x = 0.2 exhibited optimal electrical conductivity through enhanced small polaron hopping mechanism. Thermal expansion coefficient (TEC) measurements revealed excellent compatibility between the ZMCO coatings and conventional SOFC interconnect materials. These findings indicate that ZMCO coatings, particularly at x = 0.2, are promising candidates as protective layers for SOFC interconnects. | Kim, Seung Hyan; Kim, Dokyum; Oh, Seong-Uk; Lee, Jung-A; Heo, Young-Woo; Lee, Joon-Hyung | Kyungpook Natl Univ, Dept Mat Sci & Engn, Daegu 41566, South Korea | ; Lee, Hyeon/AAK-6030-2020; Lee, Jung/AAP-7829-2021 | 58803038000; 57212308311; 57856319400; 55108410500; 7004298542; 57204923460 | joonlee@knu.ac.kr; | INTERNATIONAL JOURNAL OF HYDROGEN ENERGY | INT J HYDROGEN ENERG | 0360-3199 | 1879-3487 | 102 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS | 2024 | 8.3 | 12.5 | 2.23 | 2025-05-07 | 0 | 1 | Solid oxide fuel cells; Electrophoretic deposition; Spinel; Coating; Interconnects | STAINLESS-STEEL; MANGANESE COBALTITE; ELECTROPHORETIC DEPOSITION; METALLIC INTERCONNECT; ELECTRICAL-PROPERTIES; PROTECTIVE-COATINGS; OXIDATION BEHAVIOR; OXIDE; LAYERS; FABRICATION | Coating; Electrophoretic deposition; Interconnects; Solid oxide fuel cells; Spinel | Cobalt alloys; Diffusion coatings; Electrophoretic coatings; Hard facing; Manganese alloys; Powder coatings; Protective coatings; Steel powder metallurgy; X ray powder diffraction; Zinc alloys; Zinc coatings; Critical properties; Electrophoretic depositions; Interconnect; Interconnect materials; Performance; Solid state method; Solid-oxide fuel cell; Spinel; Spinel coating; Synthesised; Manganese oxide | English | 2025 | 2025-02-10 | 10.1016/j.ijhydene.2025.01.103 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced protection of SOFC interconnects with dual coating using combined electrophoretic and sputtering methods | Chromium poisoning in 460FC stainless steel interconnects significantly impairs the performance of solid oxide fuel cells. A dual-layer coating was developed to address this issue, combining a Cu1.25Mn1.65Fe0.1O4 spinel layer, applied via electrophoretic deposition, and a Cu-Mn metal layer, deposited using sputtering. This approach demonstrated high effectiveness, producing coatings with uniform thickness and precise elemental composition. The oxidation rate was investigated by analyzing the coating's mass gain. The dual-layer coating underwent a thermal transformation, re-establishing the CuMn2O4 spinel structure through metal diffusion and forming a thick oxide scale. After 1000 h at 800 degrees C, the area-specific resistance of the SUS/EPD/SM dual-layer coated sample demonstrated excellent conductivity at 5.76 m Omega cm2. Additionally, the SUS/EPD/SM dual-layer coating provides resistance to chromium poisoning, significantly reducing the chromium content diffusing from stainless steel to the surface compared to single-layer coatings produced by each method. | Dang, Thi Huong Thao; Lee, In-Taek; Kim, Juhan; Vo, Van-Khoe; Kim, Sumi; Lim, Hyo-Jun; Lee, Jung-A; Lee, Joon-Hyung; Heo, Young-Woo | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Adv Mat Res Inst, Daegu 41566, South Korea | Lee, In-Taek/JSK-5546-2023 | 58260312800; 57855907000; 59418705700; 57938480800; 58813647900; 57338060200; 55108410500; 57204923460; 7004298542 | joonlee@knu.ac.kr; ywheo@knu.ac.kr; | INTERNATIONAL JOURNAL OF HYDROGEN ENERGY | INT J HYDROGEN ENERG | 0360-3199 | 1879-3487 | 122 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS | 2024 | 8.3 | 12.5 | 0 | 2025-05-07 | 0 | 0 | Solid oxide fuel cell; Spinel; Interconnect; Electrophoretic deposition; Sputtering; Dual-layer | OXIDE FUEL-CELL; FERRITIC STAINLESS-STEEL; METALLIC INTERCONNECTS; SPINEL OXIDES; TEMPERATURE; DEPOSITION; ALLOY; LAYER; FABRICATION; CATHODES | Dual-layer; Electrophoretic deposition; Interconnect; Solid oxide fuel cell; Spinel; Sputtering | Chromium steel; Diffusion coatings; Electrophoretic coatings; Hard facing; Manganese alloys; Manganese compounds; Melt spinning; Samarium alloys; Samarium compounds; Scale (deposits); Stainless steel; Chromium poisoning; Dual layer coatings; Dual-layers; Electrophoretic depositions; Electrophoretic methods; Interconnect; Performance; Solid-oxide fuel cell; Spinel; Sputtering methods; Sputtering | English | 2025 | 2025-04-25 | 10.1016/j.ijhydene.2025.03.366 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Green hydrogen production from thermoelectric condensation of ambient moist air | As the world transitions towards reducing carbon emissions, green hydrogen produced through solar-powered alkaline water electrolysis (AWE) presents a promising eco-friendly fuel option. In response to the challenges caused by global warming, including air moisture saturation leading to unbalanced rainfall, flooding, concern for freshwater depletion and the limited availability of water and energy sources in arid regions. The present study introduces a novel method of integrating thermoelectric water condenser (TEWC) and AWE for green hydrogen production in remote and arid regions where both the water and the conventional energy sources are scarce. Numerical simulations of the present study show that the impact of relative humidity, temperature, and air flow rate significantly affect water condensation, energy requirement, and hydrogen production. The TEWC and AWE models showed excellent agreement with the experimental data. TEWC model reveled that the highest water production rate of 1.50 kg/(m2h) is achieved at ambient air temperature of 308 K and relative humidity of 80%. Furthermore, increasing the moist air flow from 1 m/s to 2 m/s results in a 47.5% increase in water production rate. The AWE model showed that cell's performance improved with higher temperatures, lower electrodeseparator gap, and overpotentials. The hydrogen evolution rate reached a maximum of 5.2 kg/(m2h) at current density of 1.4 A/cm2 and potential of 3.96 V. By optimizing the TEWC and AWE systems the integrated method proved to be an efficient way of converting moist air into green hydrogen using solar energy, making it a viable and sustainable setup in remote arid regions. | Ahmad, Hilal; Cheema, Taqi Ahmad; Sher, Hadeed Ahmed; Park, Cheol Woo | Ghulam Ishaq Khan Inst Engn Sci & Technol, Fac Mech Engn, Topi 23640, Pakistan; Ghulam Ishaq Khan Inst Engn Sci & Technol, Fac Elect Engn, Topi 23640, Pakistan; Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | Sher, Hadeed/J-2354-2012 | 58282907300; 36522492600; 37049472400; 7408416474 | tacheema@giki.edu.pk; chwoopark@knu.ac.kr; | INTERNATIONAL JOURNAL OF HYDROGEN ENERGY | INT J HYDROGEN ENERG | 0360-3199 | 1879-3487 | 140 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS | 2024 | 8.3 | 12.5 | 0 | 2025-05-07 | 0 | 0 | TEWC; AWE; Ambient Humidified air; Numerical modelling; Multiphysics coupling | SOLAR; SYSTEM | Ambient Humidified air; AWE; Multiphysics coupling; Numerical modelling; TEWC | Clean energy; Energy efficiency; Zero-carbon; Alkaline water electrolysis; Ambient humidified air; Ambients; Carbon emissions; Moist air; Multi-physics couplings; Thermoelectric; Thermoelectric water condenser; Water condenser; Water production rate; Solar energy | English | 2025 | 2025-06-20 | 10.1016/j.ijhydene.2024.10.126 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Hierarchical design of NiFe2O4@BN/g-C3N4 Z-scheme heterojunctions for enhanced photocatalytic detoxification of tetracycline: Optimization of key parameters and H2 evolution | Developing highly efficient bifunctional photocatalysts with improved charge separation and ample active sites is a significant challenge in environmental remediation and sustainable hydrogen (H2) production. To tackle these energy and environmental issues, we synthesized highly efficient bifunctional NiFe2O4 (NF), h-BN/g-C3N4 (CBN), and NiFe2O4@BN/g-C3N4 (NF@CBN) composite photocatalysts using a surfactant-assisted hydrothermal method. Comprehensive characterization confirmed that NF nanoparticles were successfully integrated into CBN nanosheets to create robust composite structures. Among the synthesized catalysts, the NF@CBN-2 composites demonstrated excellent photocatalytic performance, achieving 98 % and 94 % tetracycline (TC) removal rates within 120 min under solar and visible light, respectively. Moreover, it showcased an outstanding hydrogen evolution rate of 1639 mu mol h-1g-1 in 1 h, and the apparent quantum yield (AQY) is approximately 26.0 % at 420 nm. Systematic optimization of reaction conditions and mechanistic studies revealed that the superoxide radical (center dot O2-) plays a crucial role in the degradation process. The enhanced photocatalytic efficiency of NF@CBN-2 results from improved charge separation, large surface area, abundant active sites, and synergistic interactions within the composite. Based on these findings, a Z-scheme photocatalytic mechanism is proposed to explain its superior activity. Furthermore, the NF@CBN composite displays excellent stability, underscoring its potential for practical applications in industrial wastewater treatment and renewable energy production. | Kumaravel, Sakthivel; Ramasundaram, Subramaniyan; Paranthaman, Vijayakumar; Prabu, Arulraj Simon; Barmavatu, Praveen; Hatshan, Mohammad Rafe; Alagarasan, Jagadeesh Kumar; Durai, Mathivanan; Gnanasekaran, Lalitha; Oh, Tae Hwan | Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Chennai 602105, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38436, South Korea; Univ Tenaga Nas, Inst Sustainable Energy ISE, Jalan IKRAM UNITEN, Kajang 43000, Selangor, Malaysia; Graph Era, Ctr Promot Res, Dehra Dun, India; St Josephs Coll Engn, Dept Elect & Commun Engn, OMR, Chennai 600119, Tamil Nadu, India; Univ Tecnol Metropolitana, Fac Engn, Dept Mech Engn, Ave Jose Pedro Alessandri 1242, Santiago, Chile; King Saud Univ, Coll Sci, Dept Chem, POB 2455, Riyadh 11451, Saudi Arabia; Manipal Univ Jaipur, Fac Sci Technol & Architecture FoSTA, Dept Chem, Jaipur 303007, Rajasthan, India; Hongik Univ, Dept Mech & Design Engn, Sejong 30016, South Korea; Chitkara Univ, Chitkara Univ Inst Engn & Technol, Ctr Res Impact & Outcome, Rajpura 140401, Punjab, India; Univ Tarapaca, Inst Alta Invest, Arica 1000000, Chile | Gnanasekaran, Lalitha/ADW-5913-2022; KUMARAVEL, SAKTHIVEL/KBC-0974-2024; Durai, Mathivanan/ABU-2023-2022; Barmavatu, Praveen/GXW-1745-2022; Alagarasan, Jagadeesh Kumar/AAW-3582-2020; Prabu, Arulraj Simon/LTZ-0958-2024; Paranthaman, Vijayakumar/HJA-5391-2022; Hatshan, Mohammad/ABG-4543-2020 | 57212580936; 24528972800; 56742208000; 57291171800; 59720911100; 57203391301; 56200680900; 57216805264; 56650900600; 57213539906 | sakthivel@knu.ac.kr; ramasundaram79@hotmail.com; Jaga.jagadeesh1987@gmail.com; mathivanand04@gmail.com; | INTERNATIONAL JOURNAL OF HYDROGEN ENERGY | INT J HYDROGEN ENERG | 0360-3199 | 1879-3487 | 134 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS | 2024 | 8.3 | 12.5 | N/A | 0 | 0 | Boron nitrate; H 2 evolution; Wastewater; Tetracycline | HYDROGEN EVOLUTION; G-C3N4 NANOSHEET; DEGRADATION; NIFE2O4; NANOCOMPOSITE; CONSTRUCTION; COMPOSITE | Boron nitrate; g-C<sub>3</sub>N<sub>4</sub>; H<sub>2</sub> evolution; NiFe<sub>2</sub>O<sub>4</sub>; Tetracycline; Wastewater | Borides; Boron nitride; Cubic boron nitride; Energy conservation; Nanosheets; Water conservation; Active site; Bi-functional; CBN composites; Charge-separation; G-C3N4; H 2 evolution; Hierarchical design; Photo-catalytic; Synthesised; Tetracycline; Photocatalytic activity | English | 2025 | 2025-06-04 | 10.1016/j.ijhydene.2025.04.511 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Review | Scalable integration of MOFs, COFs, and MXenes with g-C3N4 for solar H2 generation: A review of energy conversion strategies | Motivated by the transformative potential of photocatalytic water splitting for hydrogen (H2) production, researchers are placing greater focus on this approach due to the increasing demand for sustainable and clean energy alternatives. As a corollary, recent strides in coupling metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and MXenes with graphitic carbon nitride (g-C3N4) for solar-induced H2 generation have been brought to light in this review. MOFs, with their tunable structures and high surface areas, enhance charge separation and interfacial transport, making them ideal for constructing efficient heterojunctions with g-C3N4. COFs, featuring light elements and modular synthesis, contribute extended light absorption and abundant catalytic sites, synergizing effectively with g-C3N4 to achieve superior H2 evolution rates. Additionally, MXenes, exemplified by Ti3C2, introduce exceptional conductivity and broaden the absorption spectrum of g–C3N4–based heterojunctions, reinforcing their role in photocatalysis. Besides, this work critically examines the structural, electronic, and catalytic properties of these hybrid materials, emphasizing their impact on photocatalytic performance. The synthesis strategies for MOF/g-C3N4, COF/g-C3N4, and Ti3C2/g-C3N4 heterostructures are thoroughly reviewed, highlighting chemical compatibility and heterojunction engineering. Key approaches include precise fabrication techniques such as thermal, chemical, and physical etching for MXenes preparation and interfacial optimization for MOF and COF heterojunctions. Additionally, the recyclability and stability of these heterostructures are evaluated to assess their potential for sustainable H2 generation. Benchmark results and scaling-up strategies are discussed to provide a comprehensive roadmap for achieving solar H2 generation at practical scales. By integrating fundamental insights with cutting-edge developments, this review aims to guide future research in designing hybrid photocatalysts for a scalable and efficient H2 economy. © 2025 Hydrogen Energy Publications LLC | Husain, Ahmad; Lee, Dong-Eun; Siddiqui, Qamar Tabrez; Gunnasegaran, Prem; Danish, Mohtaram; Jo, Wan-Kuen | Institute of Power Engineering, Universiti Tenaga Nasional, Selangor, Kajang, 43000, Malaysia; School of Architecture, Civil, Environmental and Energy Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Department of Chemistry, Korea University, Seoul, South Korea; Institute of Power Engineering, Universiti Tenaga Nasional, Selangor, Kajang, 43000, Malaysia; School of Architecture, Civil, Environmental and Energy Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Architecture, Civil, Environmental and Energy Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea | 57215031715; 56605563300; 57190760136; 35778031300; 57216220743; 7103322277 | dolee@knu.ac.kr; dmohtaram@gmail.com; wkjo@knu.ac.kr; | International Journal of Hydrogen Energy | INT J HYDROGEN ENERG | 0360-3199 | 1879-3487 | 150 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS | 2024 | 8.3 | 12.5 | 0 | H<sub>2</sub> energy; Integration chemistry; Sustainable photocatalysis; Synthesis strategies; Water splitting | Economics; Heterojunctions; Hybrid materials; Hydrogen production; Photocatalysts; Photocatalytic activity; Solar energy; Solar power generation; Sustainable chemistry; Synthesis (chemical); Covalent organic frameworks; Energy; H 2 production; H2 energy; Integration chemistry; Metalorganic frameworks (MOFs); Photocatalytic water splitting; Sustainable photocatalysis; Synthesis strategy; Water splitting; Absorption spectroscopy; Light absorption | English | Final | 2025 | 10.1016/j.ijhydene.2025.150041 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

| ○ | ○ | Article | Effect of Chewing Hardness on Cognitive-Associated Brain Regions Activation | Introduction and aims: Recent findings suggest a potential correlation between mastication and cognitive processes. However, the comprehensive investigation into the neurobiological mechanisms of masticatory control, such as the impact of chewing hardness, on cognitive function, remains incomplete. This study aims to investigate the impact of chewing hardness, as an aspect of masticatory control, on cognitive function by examining brain activation patterns during hard and soft chewing conditions. Methods: A total of 52 healthy young adults (average age of 21.81 years; 24 men and 28 women) underwent fMRI scanning, during which 27 individuals chewed soft and 25 individual chewed hard material. The functional magnetic resonance imaging (fMRI) was employed to elucidate the overlapping and distinct patterns of activated brain regions associated with soft- and hard-chewing conditions. Subsequently, correlations between these activated brain regions and neuropsychological measures were assessed. Results: Conjunction analysis revealed that both soft- and hard-chewing conditions stimulated brain regions directly associated with orofacial movement and spatial information processing. Two-sample t-test result indicated that the hard-chewing group had higher activation mostly in the caudate nucleus and frontal brain regions associated with cognitive function compared with the soft-chewing group. Furthermore, the activation strength of these brain regions positively correlated with neuropsychological measures. Conclusion: The findings suggest that hard-chewing may be more effective than soft-chewing in stimulating cognition-associated brain regions, potentially enhancing cognitive processing. Clinical relevance: Our study shows that hard-chewing activates brain regions linked to cognitive function more than soft-chewing. This suggests that harder chewing could be used as a simple, non-invasive method to enhance cognitive processing. Incorporating harder foods into the diet may offer a practical approach to support cognitive health and improve mental performance. (c) 2025 The Authors.

| ○ | ○ | Article | On Achieving High-Fidelity Grant-Free Non-Orthogonal Multiple Access | Grant-free access (GFA) has been envisioned to play an active role in massive Machine Type Communication (mMTC) under 5G and Beyond mobile systems, which targets at achieving significant reduction of signaling overhead and access latency in the presence of sporadic traffic and small-size data. The paper focuses on a novel K-repetition GFA (K-GFA) scheme by incorporating Reed-Solomon (RS) code with the contention resolution diversity slotted ALOHA (CRDSA), aiming to achieve high-reliability and low-latency access in the presence of massive uncoordinated MTC devices (MTCDs). We firstly define a MAC layer transmission structure at each MTCD for supporting message-level RS coding on a data message of Q packets, where a RS code of KQ packets is generated and sent in a super time frame (STF) that is composed of Q time frames (TFs). The access point (AP) can recover the original Q packets of the data message if at least Q out of the KQ packets of the RS code are successfully received. The AP buffers the received MTCD signals of each resource block (RB) within an STF and exercises the CRDSA based multi-user detection (MUD) by exploring signal-level inter-RB correlation via iterative interference cancellation (IIC). With the proposed CRDSA based K-GFA scheme, we provide the complexity analysis, and derive a closed-form analytical model on the access probability for each MTCD as well as its simplified approximate form. Extensive numerical experiments are conducted to validate its effectiveness on the proposed CRDSA based K-GFA scheme and gain deep understanding on its performance regarding various key operational parameters. | Mei, Haoran; Peng, Limei; Ho, Pin-Han | Kyungpook Natl Univ, Sch Comp Sci & Engn, Deagu 41566, South Korea; Univ Elect Sci & Technol China, Shenzhen Inst Adv Study, Shenzhen 518110, Peoples R China | 57208655106; 59510719200; 7402211578 | auroraplm@knu.ac.kr; | IEEE OPEN JOURNAL OF THE COMMUNICATIONS SOCIETY | IEEE OPEN J COMM SOC | 2644-125X | 6 | ESCI | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2024 | 6.1 | 12.7 | 0 | 2025-05-07 | 1 | 1 | Codes; Multiuser detection; Analytical models; Diversity reception; Interference cancellation; Complexity theory; Performance evaluation; K-repetition grant-free access (K-GFA); massive machine type communication (mMTC); Reed-Solomon (RS) code; interference cancellation (IC) | IOT | interference cancellation (IC); K-repetition grant-free access (K-GFA); massive machine type communication (mMTC); Reed-Solomon (RS) code | 5G mobile communication systems; Analytical models; Codes (symbols); Multiple access interference; Code; Complexity theory; Free access; Interference cancelation; Interference cancellation; K-repetition grant-free access; Machinetype communication (MTC); Massive machine type communication; Performances evaluation; Reed -Solomon code; Multiuser detection | English | 2025 | 2025 | 10.1109/ojcoms.2024.3415373 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Optimizing electrochemical and ferroelectric synaptic devices: from material selection to performance tuning | Neuromorphic hardware systems emulate the parallel neural networks of the human brain, and synaptic weight storage elements are crucial for enabling energy-efficient information processing. They must represent multiple data states and be able to be updated analogously. In order to realize highly controllable synaptic devices, replacing the high-k gate dielectric in conventional transistor structures with either solid-electrolytes that facilitate bulk ionic motion or ferroelectric oxide allows for steady adjustment of channel currents in response to gate-voltage signals. This approach, in turn, accelerates backpropagation algorithms used for training neural networks. Furthermore, because the channel current in electrochemical random-access memory (ECRAM) is influenced by the number of mobile ions (e.g. Li+, O2-, H+ or Cu+) passing through the electrolytes, these synaptic device candidates have demonstrated an excellent linear and symmetrical channel current response when updated using an identical pulse scheme. In the latter case, which is known as the ferroelectric field-effect transistor (FeFET), the number of electrons accumulated near the channel rapidly varies with the degree of the alignment of internal dipoles in thin doped ferroelectric HfO2. This leads to a multilevel state. Based on the working principles of these two promising candidates, enabling gate-controlled ion-transport primarily in electrolytes for ECRAM and understanding the relationship between polarization and the ferroelectric layer in FeFETs are crucial to improve their properties. Therefore, this paper aims to present our recent advances, highlighting the engineering approaches and experimental findings related to ECRAM and FeFET for three-terminal synaptic devices. | Kim, Eunjin; Jeon, Seonuk; Park, Hyoungjin; Jeong, Jiae; Choi, Hyeonsik; Kim, Yunsur; Kim, Jihyun; Lim, Seokjae; Moon, Kibong; Woo, Jiyong | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IC Design Educ Ctr, Daegu 41566, South Korea; Pohang Univ Sci & Technol, Dept Mat Sci & Engn, Pohang 37673, South Korea | 57222322113; 57955098300; 58964076600; 58963433800; 58835686900; 58847712800; 59361845100; 56525744000; 55921226700; 53985749100 | kbmoon@postech.ac.kr; jiyong.woo@knu.ac.kr; | NEUROMORPHIC COMPUTING AND ENGINEERING | NEUROMORPH COMPUT EN | 2634-4386 | 5 | 1 | ESCI | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2024 | 6.1 | 12.7 | 0 | 2025-05-07 | 0 | 0 | electrochemical; ferroelectric; synaptic; devices | SWITCHING ENDURANCE; THIN-FILMS; MEMORY; BEHAVIOR; ANTIFERROELECTRICITY; TRANSISTORS; EVOLUTION; NETWORK; ARRAY; HFO2 | devices; electrochemical; ferroelectric; synaptic | English | 2025 | 2025-03-01 | 10.1088/2634-4386/adb512 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Article | Twin Delayed DDPG (TD3)-Based Edge Server Selection for 5G-Enabled Industrial and C-ITS Applications | In the 3GPP-defined edge computing architecture, User Equipment (UE) interacts with the Edge Enabler Layer to request application services. The Edge Enabler Client (EEC) forwards these requests to the Edge Enabler Server (EES), which leverages the 3GPP core network for UE analytics, such as location and Quality-of-Service (QoS) requirements, to identify the optimal Edge Application Server (EAS). The Edge Configuration Server (ECS) then provisions the configurations for connecting the UE to the selected EAS. While this architecture provides a robust framework, finding the most appropriate EAS for task execution remains a critical challenge in heterogeneous environments where Cooperative Intelligent Transportation Systems (C-ITS) and industrial 5G applications coexist. The diverse nature of applications, such as latency-critical safety tasks in C-ITS and throughput-intensive industrial applications like real-time robotics, makes it essential to intelligently map tasks to edge servers. Additionally, uneven task distribution and server overloading necessitate mechanisms for dynamic load sharing between edge servers in the Edge Data Network (EDN). This paper proposes an AI-driven framework for optimal edge server selection and collaborative load management in 5G-enabled C-ITS and industrial environments. Twin Delayed Deep Deterministic Gradient Policy (TD3) based framework is proposed to dynamically assign tasks to the most suitable EAS while considering constraints such as low latency, high throughput, computation resources, and bandwidth resources. Furthermore, it introduces an edge node-sharing mechanism to offload tasks from overloaded servers to neighboring nodes, ensuring balanced resource utilization and seamless service delivery. | Saad, Malik Muhammad; Jamshed, Muhammad Ali; Adedamola, Abdulhameed Idris; Nauman, Ali; Kim, Dongkyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Univ Glasgow, Coll Sci & Engn, Glasgow, Scotland; Yeungnam Univ, Sch Comp Sci & Engn, Gyongsan, South Korea | Nauman, Ali/KJD-5577-2024; Saad, Malik/ABF-9433-2021; Jamshed, Muhammad Ali/AAB-3421-2019 | 57220715290; 57468974000; 59762245600; 57210321511; 35753648800 | dongkyun@knu.ac.kr; | IEEE OPEN JOURNAL OF THE COMMUNICATIONS SOCIETY | IEEE OPEN J COMM SOC | 2644-125X | 6 | ESCI | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2024 | 6.1 | 12.7 | 0 | 2025-05-07 | 0 | 0 | 5G mobile communication; Service robots; Quality of service; Computer architecture; Throughput; Load management; Servers; Resource management; Intelligent transportation systems; Edge computing; Edge application server (EAS); 5G edge computing; resource allocation; task offloading | 5G edge computing; Edge application server (EAS); resource allocation; task offloading | Computation offloading; 5g edge computing; Application Servers; Edge application server; Edge computing; Edge server; Intelligent transportation systems; Resources allocation; Server selection; Task offloading; User equipments; 5G mobile communication systems | English | 2025 | 2025 | 10.1109/ojcoms.2025.3545566 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Cancer incidence and the influence of immunosuppressive agents in Korean patients with systemic lupus erythematosus: a retrospective cohort study | BackgroundTo investigate cancer incidence and the potential influence of immunosuppressive agents in Korean systemic lupus erythematosus (SLE) patients.MethodsWe conducted a retrospective analysis utilizing data from the Korea Healthcare Bigdata Linked Platform, which integrated the National Central Cancer Registry and National Health Insurance Service databases covering the period 2008-2017. Incidence rates (IRs) per 10,000 person-years (PYs) for site-specific cancers of SLE patients were calculated using ICD-O-3 codes. Multivariable logistic regression analysis was utilized to assess the association between immunosuppressive agents and cancer development in SLE patients.ResultsA total of 10,013 predominantly female (91%) Korean SLE patients with a mean age of 36.9 +/- 15.2 years were included. During a follow-up of 62,268.5 PYs, 368 patients developed cancer. The IRs per 10,000 PYs for total, solid, and hematologic cancers were 59.07, 54.09, and 5.78, respectively. The most prevalent cancers (measured in IRs per 10,000 PYs) were thyroid (17.01, 95% CI 13.78-20.25), breast (8.67, 95% CI 6.36-10.98), stomach (4.49, 95% CI 2.83-6.16), colorectal (4.17, 95% CI 2.57-5.78), and cervical (3.85, 95% CI 2.31-5.39). Approximately half (50.8%) of SLE patients with cancer were diagnosed at the localized Surveillance, Epidemiology, and End Results (SEER) stage. No statistically significant association was found between immunosuppressive agents and cancer development (Odds Ratio 1.03, 95% CI 0.80-1.34).ConclusionOur study shows that Korean SLE patients using immunosuppressive agents are not significantly more likely to develop cancer. Further research with extended observation is warranted to corroborate these findings. | Cho, Soo-Kyung; Han, Jung-Yong; Jeon, Yena; You, Seung-Hun; Jung, Sun-Young; Jang, Eun Jin; Sung, Yoon-Kyoung | Hanyang Univ, Dept Rheumatol, Hosp Rheumat Dis, Seoul 04763, South Korea; Hanyang Univ, Inst Rheumatol Res, Seoul, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Chung Ang Univ, Coll Pharm, Seoul, South Korea; Andong Natl Univ, Dept Data Sci, Andong, South Korea | 35185890800; 57220065429; 57209909350; 57211440504; 57207445502; 37861741600; 15754508900 | sungyk@hanyang.ac.kr; | ARTHRITIS RESEARCH & THERAPY | ARTHRITIS RES THER | 1478-6354 | 1478-6362 | 27 | 1 | SCIE | RHEUMATOLOGY | 2024 | 4.6 | 12.9 | 0 | 2025-05-07 | 0 | 0 | Systemic lupus erythematosus; Cancer; Incidence rate; Immunosuppressive agents | NON-HODGKINS-LYMPHOMA; THYROID-CANCER; RISK; MALIGNANCIES; DISEASE; BREAST | Cancer; Immunosuppressive agents; Incidence rate; Systemic lupus erythematosus | Adult; Cohort Studies; Female; Humans; Immunosuppressive Agents; Incidence; Lupus Erythematosus, Systemic; Male; Middle Aged; Neoplasms; Registries; Republic of Korea; Retrospective Studies; Young Adult; azathioprine; cyclophosphamide; cyclosporine; immunosuppressive agent; leflunomide; methotrexate; mizoribine; mycophenolic acid; tacrolimus; immunosuppressive agent; adult; age; aged; Article; breast cancer; cancer diagnosis; cancer incidence; cancer registry; cancer staging; cohort analysis; colorectal cancer; confidence interval; controlled study; disease association; female; follow up; gender; hematologic malignancy; human; ICD-O-3; immunosuppressive treatment; Korea; Korean (people); major clinical study; male; malignant neoplasm; multivariate logistic regression analysis; national health insurance; observational study; odds ratio; prevalence; retrospective study; solid malignant neoplasm; statistical significance; stomach cancer; systemic lupus erythematosus; thyroid cancer; uterine cervix cancer; epidemiology; incidence; middle aged; neoplasm; register; South Korea; systemic lupus erythematosus; young adult | English | 2025 | 2025-01-22 | 10.1186/s13075-025-03482-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficacy and safety of epaminurad, a potent hURAT1 inhibitor, in patients with gout: a randomized, placebo-controlled, dose-finding study | Background Gout is the most common inflammatory arthritis. Current urate-lowering therapies have limitations, such as adverse drug reactions or limited efficacy. Epaminurad is a novel selective human urate transporter 1 (hURAT1) inhibitor that has been shown to reduce serum urate (sUA) levels in healthy volunteers and patients with gout. The aims of the current study were to evaluate the urate-lowering efficacy and safety of epaminurad compared with placebo in patients with gout, and to determine the optimal dose. Methods This multicenter, randomized, double-blind, placebo-controlled, dose-finding phase 2b clinical trial, which incorporated a standard-treatment reference arm, enrolled patients aged 19-70 years with gout and sUA level >= 0.42 mmol/L. Participants received gout prophylaxis and followed therapeutic lifestyle changes, and were randomized to receive epaminurad 3 mg, 6 mg or 9 mg, or febuxostat 80 mg, or matching placebo, once daily for 12 weeks. The primary efficacy endpoint was the proportion of patients with sUA level 90% in all groups. The proportion of patients with sUA < 0.36 mmol/L at week 4 was significantly higher in each epaminurad group (9 mg, 88.89%; 6 mg, 71.79%; 3 mg, 54.05%) compared with placebo (0.00%) (all p < 0.0001). The response rate in the febuxostat group was 84.21%. The proportion of patients who achieved sUA < 0.30 mmol/L, and mean percent and absolute change in sUA, were also significantly greater in all epaminurad groups versus placebo at week 4. Outcomes were consistent at weeks 8 and 12. The adverse event rate did not differ between epaminurad groups and placebo, and most events were mild. There were no significant differences in mean serum creatinine levels or liver function parameters between the epaminurad groups and placebo. Conclusions Epaminurad was effective at reducing sUA levels in patients with gout. The study also confirmed the safety and tolerability profile during 12 weeks of treatment.

| ○ | Article | Risk and Mortality of Cardiovascular Diseases in Patients with Dupuytren Disease: A Nationwide Population-Based Cohort Study | Background: Dupuytren disease (DD) is a type of fibroproliferative disease that involves the palmar aspect of the hand. Although many benign fibroproliferative diseases have been shown to increase the risk of cardiovascular disease, the relationship between DD and myocardial infarction (MI) or stroke has not been fully elucidated. Methods: A total of 35,909 patients with DD and a control cohort with 1,077,270 age- and sex-matched participants from the Korean National Health Insurance database were included. The incidences of MI, stroke, and survival after cardiovascular events, were compared between participants with DD and the control cohort. Results: Compared with the control cohort, the incidence rate ratios for cardiovascular diseases in DD were as follows: 1.51 (95% CI, 1.44 to 1.58) for MI; 2.01 (95% CI, 1.94 to 2.09) for ischemic stroke (IS); and 1.49 (95% CI, 1.36 to 1.63) for hemorrhagic stroke . After adjusting for other cardiovascular disease risk factors, DD was associated with an increased risk of IS. Based on the age-, sex-, and body mass index-stratified analyses, an increased risk of MI was identified in the younger age group (<50 years) and thin subjects (body mass index < 18.5 kg/m(2)). Adjusted hazard ratios for mortality in subjects with DD who developed cardiovascular diseases were 0.51 (95% CI, 0.43 to 0.60), 0.56 (95% CI, 0.50 to 0.62), and 1.08 (95% CI, 0.86 to 1.36), respectively. Conclusions: DD is associated with an increased risk of IS, independent of cardiovascular risk factors. DD is also associated with an increased risk of MI in individuals younger than 50 years. DD did not significantly aggravate mortality secondary to cardiovascular events.CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II. | Ryu, Jeong Yeop; Park, Tae Hwan; Lee, Joon Seok; Choi, Kang Young; Yang, Jung Dug; Chung, Ho Yun | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 680 Gukchaebosanro, Daegu 41405, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Sch Med, Daegu, South Korea | prsryu@knu.ac.kr; | PLASTIC AND RECONSTRUCTIVE SURGERY | PLAST RECONSTR SURG | 0032-1052 | 1529-4242 | 156 | 1 | SCIE | SURGERY | 2024 | 3.4 | 13.0 | 1 | English | 2025 | 2025-07 | 10.1097/prs.0000000000011944 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Sources and Dynamics of Dissolved Organic Carbon in Kongsfjorden: Insights From Radiocarbon Analysis | The Arctic is undergoing rapid warming, resulting in accelerating glacier melt and release of nutrients, particles, and organic matter into coastal fjord systems. Kongsfjorden, a fjord in Svalbard, serves as a natural laboratory for investigating climate-driven shifts in high-latitude fjord ecosystems and their broader implications for the Arctic. To examine dissolved organic carbon (DOC) sources and cycling in Kongsfjorden, we collected samples of seawater, floating ice, and river water in June 2023 and analyzed 14C and 13C in DOC. Radiocarbon values of DOC (as in Delta 14C) in fjord seawater ranged from -302 parts per thousand to -253 parts per thousand, while values in the Bayelva River were higher, suggesting a contribution of younger, terrigenous DOC. However, stable carbon isotope results suggested rapid removal of riverine DOC after entering the fjord. Additionally, differences in Delta 14C values between the inner and outer fjord reflected varying contributions from surface primary production and glacial meltwater inputs. | Oh, Sunmin; Fang, Ling; Kim, Jeonghyun; Yang, Eun Jin; Hwang, Jeomshik; Kim, Minkyoung | Seoul Natl Univ, Res Inst Oceanog, Sch Earth & Environm Sci, Seoul, South Korea; Northwest Univ, Urban & Environm Sci Dept, Shaanxi Key Lab Earth Surface Syst & Environm Carr, Xian, Peoples R China; Jeju Natl Univ, Coll Ocean Sci, Dept Earth & Marine Sci, Jeju, South Korea; Korea Polar Res Inst, Div Ocean Sci, Incheon, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Sch Earth Syst Sci, KNU G LAMP Project Grp, Daegu, South Korea | 59758407900; 58183605000; 56262443600; 7202021201; 7403896714; 57212315624 | lingfang@nwu.edu.cn; minkyoung@knu.ac.kr; | GEOPHYSICAL RESEARCH LETTERS | GEOPHYS RES LETT | 0094-8276 | 1944-8007 | 52 | 8 | SCIE | GEOSCIENCES, MULTIDISCIPLINARY | 2024 | 4.6 | 13.0 | 0 | 2025-05-07 | 0 | 0 | dissolved organic carbon; radiocarbon; carbon cycle; Kongsfjorden; Svalbard | MATTER; GLACIERS; SYSTEM; EXTRACTION; KROSSFJORDEN; TERRESTRIAL; ENVIRONMENT; ANCIENT; CYCLES; EXPORT | carbon cycle; dissolved organic carbon; Kongsfjorden; radiocarbon; Svalbard | Arctic; Bayelva; Kongsfjorden; Spitsbergen; Svalbard; Svalbard; Svalbard and Jan Mayen; Accelerating glacier melts; Carbon cycles; Dissolved organic carbon; High Latitudes; Kongsfjorden; Natural laboratories; Organics; Radiocarbon; Radiocarbon analysis; Svalbard; carbon cycle; dissolved organic carbon; floating ice; meltwater; primary production; radiocarbon dating; river water; seawater; stable isotope; Glacial geology | English | 2025 | 2025-04-28 | 10.1029/2025gl114917 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
