○ ○ Article ⓘ Quantitative computed tomography imaging classification of cement dust-exposed patients-based Kolmogorov-Arnold networks ⓘ Background: Occupational health assessment is critical for detecting respiratory issues caused by harmful exposures, such as cement dust. Quantitative computed tomography (QCT) imaging provides detailed insights into lung structure and function, enhancing the diagnosis of lung diseases. However, its high dimensionality poses challenges for traditional machine learning methods. Methods: In this study, Kolmogorov-Arnold networks (KANs) were used for the binary classification of QCT imaging data to assess respiratory conditions associated with cement dust exposure. The dataset comprised QCT images from 609 individuals, including 311 subjects exposed to cement dust and 298 healthy controls. We derived 141 QCT-based variables and employed KANs with two hidden layers of 15 and 8 neurons. The network parameters, including grid intervals, polynomial order, learning rate, and penalty strengths, were carefully finetuned. The performance of the model was assessed through various metrics, including accuracy, precision, recall, F1 score, specificity, and the Matthews Correlation Coefficient (MCC). A five-fold cross-validation was employed to enhance the robustness of the evaluation. SHAP analysis was applied to interpret the sensitive QCT features. Results: The KAN model demonstrated consistently high performance across all metrics, with an average accuracy of 98.03 %, precision of 97.35 %, recall of 98.70 %, F1 score of 98.01 %, and specificity of 97.40 %. The MCC value further confirmed the robustness of the model in managing imbalanced datasets. The comparative analysis demonstrated that the KAN model outperformed traditional methods and other deep learning approaches, such as TabPFN, ANN, FT-Transformer, VGG19, MobileNets, ResNet101, XGBoost, SVM, random forest, and decision tree. SHAP analysis highlighted structural and functional lung features, such as airway geometry, wall thickness, and lung volume, as key predictors. Conclusion: KANs significantly improved the classification of QCT imaging data, enhancing early detection of cement dust-induced respiratory conditions. SHAP analysis supported model interpretability, enhancing its potential for clinical translation in occupational health assessments. ⓘ Chau, Ngan-Khanh; Kim, Woo Jin; Lee, Chang Hyun; Chae, Kum Ju; Jin, Gong Yong; Choi, Sanghun ⓘ Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea; Kyungpook Natl Univ, IEDT, Daegu, South Korea; Vietnam Natl Univ Ho Chi Minh City, Giang Univ, Ho Chi Minh, Vietnam; Kangwon Natl Univ, Kangwon Natl Univ Hosp, Sch Med, Dept Internal Med, Chunchon, South Korea; Kangwon Natl Univ, Kangwon Natl Univ Hosp, Environm Hlth Ctr, Sch Med, Chunchon, South Korea; Seoul Natl Univ, Coll Med, Dept Radiol, Seoul, South Korea; Univ Iowa, Coll Med, Dept Radiol, Iowa City, IA USA; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Biomed Res Inst, Dept Radiol,Res Inst Clin Med, Jeonju, South Korea ⓘ Ngân Khánh, Châu/IUM-5515-2023 ⓘ 57658928300; 59063248500; 59484814300; 59712194800; 59920950200; 55847101000 ⓘ s-choi@knu.ac.kr; ⓘ ARTIFICIAL INTELLIGENCE IN MEDICINE ⓘ ARTIF INTELL MED ⓘ 0933-3657 1873-2860 167 SCIE COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ENGINEERING, BIOMEDICAL;MEDICAL INFORMATICS ⓘ 2024 6.2 13.5 0 2025-06-11 ⓘ 0 0 Kolmogorov-Arnold networks; Computed tomography; Quantitative computed tomography; Cement dust exposure; Lung imaging; Occupational health assessment ⓘ ⓘ Cement dust exposure; Computed tomography; Kolmogorov-Arnold networks; Lung imaging; Occupational health assessment; Quantitative computed tomography ⓘ cement; Cement dust; Cement dust exposure; Computed tomography; Health assessments; Kolmogorov; Kolmogorov-arnold network; Lung imaging; Occupational health; Occupational health assessment; Quantitative computed tomographies; aged; airway; Article; artificial neural network; binary classification; body height; body mass; body weight; computer assisted tomography; controlled study; cross validation; decision tree; deep learning; dust exposure; feature extraction; female; forced expiratory volume; forced vital capacity; functional residual capacity; human; image registration; inspiratory capacity; kolmogorov arnold network; lung emphysema; lung lobe; lung volume; machine learning; main bronchus; major clinical study; male; multilayer perceptron; random forest; residual neural network; respiratory tract parameters; Shapley additive explanation; small airway disease; support vector machine; total lung capacity; Lung cancer ⓘ English 2025 2025-09 10.1016/j.artmed.2025.103166 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Ultrathin (<10 nm) Electrochemical Random-Access Memory that Overcomes the Tradeoff between Robust Weight Update and Speed in Neuromorphic Systems ⓘ Electrochemical random-access memory (ECRAM) devices are a promising candidate for neuromorphic computing, as they mimic synaptic functions by modulating conductance through ion migration. However, the use of a thick electrolyte layer (>40 nm) in conventional ECRAMs leads to an unavoidable tradeoff between synaptic weight updates and operating speed. To address this problem, a Cu-based ultrathin ECRAM (UT-ECRAM) that uses a single 5 nm HfOx active layer and a ≈1.2 nm AlOx liner is designed. The highly efficient gate-tunable fast Cu-ion transport in the AlOx/HfOx UT-ECRAM enables 1) near-ideal linearity in weight updates (0.45) even achieved with a pulse width (tw) of 50 μs, 2) dynamic multilevel retention of 104 s, and 3) reliable cycling endurance of 104 cycles. A numerical analysis based on device scaling quantitatively reveals that a relatively high concentration of field-driven Cu ions (≈1020 cm−3) contributes to each synaptic weight update per gate voltage (VG) pulse in the UT-ECRAM without becoming deactivated by traversing thicker layers. This improved gate sensitivity can ultimately overcome the linearity and the ratio/speed tradeoff relationships, paving the way for robust neuromorphic synaptic units. © 2025 The Author(s).

○ ○ Review ⓘ Electrocatalyst design strategies towards high performance anion-exchange membrane-based direct ammonia fuel cells ⓘ Direct ammonia fuel cells (DAFCs) with anion-exchange membranes (AEMs) are considered a valuable contributor to a carbon-neutral clean energy society, benefitting from the existence of long-established ammonia infrastructure. However, the relatively low cell performance of DAFCs compared to the hydrogen-based fuel cells and the critical issues related to catalyst poisoning limit the widespread use of DAFCs and have spurred multi-directional efforts to develop tailored catalyst compositions and structures specific to DAFCs. In this review, we outline recent progress in the development of electrocatalysts for DAFCs. First, we summarize the operating principles of DAFCs and address critical challenges in electrode reactions, the ammonia oxidation reaction (AOR) and oxygen reduction reaction (ORR). Subsequently, we present an overview of recent endeavours to enhance activity, selectivity, and durability of catalysts for each electrode reaction. We categorize the electrocatalytic exemplars into platinum group metal (PGM) and non-PGM compositions and provide systematic comparisons of each strategy to provide a more comprehensive understanding of catalyst design. Lastly, this review highlights remaining challenges and offers insights into future directions for optimizing DAFC performance. ⓘ Kim, Ho Young; Kim, Jungki; Lee, Eunsoo; Choi, Hyoryeong; Chun, Hyunsoo; Kundu, Joyjit; Choi, Sang-Il; Lee, Kwangyeol; Kim, Jin Young ⓘ Sangmyung Univ, Dept Chem & Energy Engn, Seoul 03016, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Korea Univ, Dept Chem, Seoul 02841, South Korea; Korea Univ, Res Inst Nat Sci, Seoul 02841, South Korea; Seoul Natl Univ, Dept Mech Engn, Seoul 08826, South Korea; Korea Inst Sci & Technol KIST, Hydrogen Fuel Cell Res Ctr, Seoul 02792, South Korea; Korea Natl Univ Sci & Technol UST, KIST Sch, Div Energy & Environm Technol, Seoul 02792, South Korea ⓘ Kim, Yong-Tae/HQZ-0240-2023; Chung, Chan-Hwa/D-5194-2011; Kim, Ho Young/GRR-2801-2022; Choi, Sang-Il/AGR-1133-2022; Kundu, Joyjit/AAY-7466-2021; Choi, Sang-Il/N-7571-2013 ⓘ 57261006300; 59544326300; 58856466500; 59543773100; 57206665881; 57209325902; 56167600800; 8510322900; 57217845971 ⓘ sichoi@knu.ac.kr; kylee1@korea.ac.kr; jinykim@kist.re.kr; ⓘ JOURNAL OF MATERIALS CHEMISTRY A ⓘ J MATER CHEM A ⓘ 2050-7488 2050-7496 13 9 SCIE CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 9.5 13.6 0 2025-05-07 ⓘ 0 0 ⓘ OXYGEN REDUCTION REACTION; ELECTROCHEMICAL OXIDATION; PLATINUM NANOPARTICLES; METAL NANOPARTICLES; HYDROGEN OXIDATION; CATALYTIC-ACTIVITY; ALCOHOL OXIDATION; ANODIC-OXIDATION; ALKALINE MEDIA; PT/C CATALYSTS ⓘ ⓘ Electrolysis; Electrolytic reduction; Hydrogen fuels; Integrated circuit design; Mendelevium; Oxygen reduction reaction; Proton exchange membrane fuel cells (PEMFC); A-carbon; Anion exchange; Design strategies; Direct ammonia fuel cells; Electrode reactions; Exchange membranes; Membrane-based; Performance; Platinum group metals; ]+ catalyst; Ammonia ⓘ English 2025 2025-02-25 10.1039/d4ta07723g ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Ligand environment engineering of nickel single atomic sites for efficient electrochemical carbon dioxide reduction reaction ⓘ The electrochemical carbon dioxide reduction reaction (CO2RR) is considered one of the feasible options for a net reduction of CO2 emissions, especially when coupled with renewable energy resources. Many techno-economical assessments on the CO2RR have concluded that the production of syngas (CO/H2), a precursor for Fischer-Tropsch synthesis, is beneficial. Thus, cost-effective and durable catalysts are needed to selectively promote the CO2RR to produce syngas. Ni-based single-atom catalysts (Ni-SACs) have gained significant interest for the CO2RR towards syngas production. However, there is still a lack of understanding of the physicochemical properties of isolated Ni atomic sites with different ligand environments and the resultant CO2RR performance. In this study, we combined experimental measurements, in situ X-ray absorption fine structure analyses, and density functional theory calculations to study a series of Ni-SACs with controlled Ni configuration and N-coordination and revealed that Ni-Nx sites with less than 4 N coordination are the catalytically active sites for the selective CO2RR process. This study provides fundamental insights into the rational design for Ni-SACs for enhanced CO2RR activity and selectivity based on their structure-property relationship. ⓘ Kim, Min Sung; Priyadarsini, Adyasa; Lee, Ju-Hyeon; Bae, Jin-Gyu; Heo, Jeong Yeon; Lee, Hyeon Jeong; Kattel, Shyam; Lee, Ji Hoon ⓘ Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Adv Mat Res Inst, Daegu 41566, South Korea; Florida A&M Univ, Dept Phys, Tallahassee, FL 32307 USA; Ulsan Natl Inst Sci & Technol, Dept Mat Sci & Engn, Ulsan 44919, South Korea; Univ Cent Florida, Dept Phys, Orlando, FL 32816 USA ⓘ PRIYADARSINI, ADYASA/AAG-5055-2019; Lee, Ji/AAU-7285-2021; Kattel, Shyam/AAK-6985-2020; Lee, Ji Hoon/T-4913-2017; Lee, Ju/M-8764-2019 ⓘ ⓘ hyeonjeong.lee@unist.ac.kr; shyam.kattel@ucf.edu; jihoonlee@knu.ac.kr; ⓘ JOURNAL OF MATERIALS CHEMISTRY A ⓘ J MATER CHEM A ⓘ 2050-7488 2050-7496 13 5 SCIE CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 9.5 13.6 ⓘ 2 ⓘ CO2; GRAPHENE; CATALYSTS; WATER; ELECTROREDUCTION; NANOPARTICLES; ELECTROLYSIS; ADSORPTION; OXIDATION; COPPER ⓘ ⓘ ⓘ English 2025 2025-01-28 10.1039/d4ta06720g ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Upgrading the COSINE-100 experiment for enhanced sensitivity to low-mass dark matter detection ⓘ The DAMA/LIBRA experiment has reported an annual modulation signal in NaI(Tl) detectors, which has been interpreted as a possible indication of dark matter interactions. However, this claim remains controversial, as several experiments have tested the modulation signal using NaI(Tl) detectors. Among them, the COSINE-100 experiment, specifically designed to test DAMA/LIBRA's claim, observed no significant signal, revealing a more than 3 sigma discrepancy with DAMA/LIBRA's results. Here we present COSINE-100U, an upgraded version of the experiment, which aims to expand the search for dark matter interactions by improving light collection efficiency and reducing background noise. The detector, consisting of eight NaI(Tl) crystals with a total mass of 99.1 kg, has been relocated to Yemilab, a new underground facility in Korea, and features direct PMT-coupling technology to enhance sensitivity. These upgrades significantly improve the experiment's ability to probe low-mass dark matter candidates, contributing to the ongoing global effort to clarify the nature of dark matter. ⓘ Lee, Doohyeok; Cho, Jae Young; Ha, Chang Hyon; Jeon, Eunju; Kim, Hongjoo; Kim, Jinyoung; Kim, Kyungwon; Kim, Sunghyun; Kim, Sun Kee; Kim, Won Kyung; Kim, Yeongduk; Ko, Young Ju; Lee, Hyunseok; Lee, Hyun Su; Lee, In Soo; Lee, Jaison; Lee, Seo Hyun; Lee, Seung Mok; Maruyama, Reina H.; Park, Jong-Chul; Park, Kangsoon; Park, Kihong; Park, Se Dong; Seo, Kyungmin; Son, Min Ki; Yu, Gyun Ho ⓘ Kyungpook Natl Univ, Dept Phys, Daegu, South Korea; Chung Ang Univ, Dept Phys, Seoul, South Korea; Inst for Basic Sci Korea, Ctr Underground Phys, Daejeon, South Korea; Seoul Natl Univ Univ, Dept Phys, Seoul 08826, South Korea; Univ Sci & Technol, IBS Sch, Daejeon, South Korea; Jeju Natl Univ, Dept Phys, Jeju, South Korea; Yale Univ, Dept Phys, New Haven, CT USA; Yale Univ, Wright Lab, New Haven, CT USA; Chungnam Natl Univ, Dept Phys, Daejeon, South Korea; Chungnam Natl Univ, IQS, Daejeon, South Korea ⓘ ; Maruyama, Reina/A-1064-2013; Ko, Young/AEI-0838-2022 ⓘ 59639095100; 57204422573; 17342119700; 57204519171; 58483690400; 57216886668; 57209988432; 7601588326; 59102407800; 55492072500; 7410207253; 56030036300; 56733823100; 56113238600; 55816685400; 57226402706; 57257129200; 55902330700; 9334469000; 57202928358; 35225979300; 57222540335; 57207888152; 56647489700; 59737457800; 57208174900 ⓘ hyunsulee@ibs.re.kr; islee@ibs.re.kr; ⓘ COMMUNICATIONS PHYSICS ⓘ COMMUN PHYS-UK ⓘ 2399-3650 8 1 SCIE PHYSICS, MULTIDISCIPLINARY ⓘ 2024 5.8 13.6 0 2025-05-07 ⓘ 0 0 ⓘ ANNUAL MODULATION; SEARCH ⓘ ⓘ Signal modulation; Annual modulations; Background noise; Coupling technology; Dark matter; Dark matter detection; Enhanced sensitivity; Light collection efficiency; Low-mass; Modulation signals; Total mass; Dark Matter ⓘ English 2025 2025-04-04 10.1038/s42005-025-02067-4 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhancing virus-mediated genome editing for cultivated tomato through low temperature ⓘ Key messageViral vector-mediated gene editing is enhanced for cultivated tomato under low temperature conditions, enabling higher mutation rates, heritable, and virus-free gene editing for efficient breeding. The CRISPR/Cas system, a versatile gene-editing tool, has revolutionized plant breeding by enabling precise genetic modifications. The development of robust and efficient genome-editing tools for crops is crucial for their application in plant breeding. In this study, we highly improved virus-induced genome-editing (VIGE) system for cultivated tomato. Vectors of tobacco rattle virus (TRV) and potato virus X (PVX) were used to deliver sgRNA targeting phytoene desaturase (SlPDS), along with mobile RNA sequences of tFT or tRNAIleu, into Cas9-overexpressing cultivated tomato (S. lycopersicum cv. Moneymaker). Our results demonstrate that low temperature significantly enhanced viral vector-mediated gene editing efficiency in both cotyledons and systemic upper leaves. However, no mutant progeny was obtained from TRV- and PVX301-infected MM-Cas9 plants. To address this challenge, we employed tissue culture techniques and found that low-temperature incubations at the initiation stage of tissue culture lead to enhanced editing efficiency in both vectors, resulting in a higher mutation rate (> 70%) of SlPDS in regenerated plants. Heritable gene-edited and virus-free progenies were successfully identified. This study presents a straightforward approach to enhance VIGE efficiency and the expeditious production of gene-edited lines in tomato breeding. ⓘ Kang, Ga Hui; Ko, Yujung; Lee, Je Min ⓘ Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea ⓘ Lee, Je Min/F-9797-2014; Lee, Je/AAE-7496-2020 ⓘ 57222099284; 59501817300; 8885729900 ⓘ jemin@knu.ac.kr; ⓘ PLANT CELL REPORTS ⓘ PLANT CELL REP ⓘ 0721-7714 1432-203X 44 1 SCIE PLANT SCIENCES ⓘ 2024 4.5 13.7 4.69 2025-05-07 ⓘ 5 5 Tomato; Virus-induced genome editing; CRISPR-Cas9; Tobacco rattle virus; Potato virus X; Low temperature ⓘ CAMV 35S PROMOTER; GENE; CRISPR/CAS9; TRANSFORMATION; DEFENSE ⓘ CRISPR-Cas9; Low temperature; Potato virus X; Tobacco rattle virus; Tomato; Virus-induced genome editing ⓘ Cold Temperature; CRISPR-Cas Systems; Gene Editing; Genetic Vectors; Genome, Plant; Oxidoreductases; Plant Breeding; Plant Leaves; Plant Viruses; Plants, Genetically Modified; Potexvirus; Secoviridae; Solanum lycopersicum; Tobacco rattle virus; oxidoreductase; phytoene dehydrogenase; cold; CRISPR Cas system; gene editing; gene vector; genetics; plant breeding; plant genome; plant leaf; plant virus; Potexvirus; procedures; Secoviridae; Tobacco rattle virus; tomato; transgenic plant; virology ⓘ English 2025 2025-01 10.1007/s00299-024-03392-8 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Psychological and biological stress pathways as common mechanisms underlying a psycho-neurological symptom cluster in cancer patients: Perceived stress, cortisol, and ACTH ⓘ Purpose: This study aimed to examine (a) whether psychological stress is associated with experiencing multiple psycho-neurological symptoms (depression, cognitive impairment, fatigue, sleep disturbance, and pain) as a cluster and (b) whether stress hormones (adrenocorticotropic hormone [ACTH] and cortisol) are associated with psychological stress and symptom cluster experience. Methods: This cross-sectional study analyzed data from 133 patients with hematologic cancer awaiting chemotherapy. Enzyme-linked immunosorbent assays analyzed the morning stress hormone levels (ACTH and cortisol). Latent profile analyses identified the group experiencing a psycho-neurological symptom cluster. Factors influencing the experience of the psycho-neurological symptom cluster were included as covariates and analyzed using multinomial logistic regression. Results: Thirty-three percent (n = 44) experienced all five psycho-neurological symptoms as a cluster and experienced each symptom in a higher severity than those who did not experience the symptom cluster (ps < 0.05). Thereby, this group legitimately experienced the psycho-neurological symptom cluster. The major determinant of this group was the perceived psychological stress (OR = 8.05, 95% CI = 3.08; 20.99). Further, each symptom demonstrated a positive association with stress levels (correlation r ranged from 0.22 to 0. 56, all ps < 0.05). Participants with higher stress were more likely to experience the symptom cluster. Stress hormones levels (ACTH and cortisol) were neither associated with the symptom cluster experience nor with psychological stress levels. Conclusions: Psychological stress, rather than biological stress response, is involved in experiencing the psychoneurological symptom cluster. Managing stress levels would help alleviate this symptom cluster. ⓘ Kim, Hee-Ju; Chae, Kyung Mi; Jung, Sun-Ok; Chung, Su Wol; Raykov, Tenko ⓘ Catholic Univ Korea, Coll Nursing, Seoul, South Korea; Kyungpook Natl Univ Hosp, Nursing Dept, Daegu, South Korea; Suwon Sci Coll, Dept Nursing, Gyeonggi, South Korea; Univ Ulsan, Coll Nat Sci, Dept Biol Sci, Ulsan, South Korea; Michigan State Univ, Measurement & Quantitat Methods, E Lansing, MI USA ⓘ ⓘ 36072412200; 59410547100; 57214691064; 57572571900; 7007171074 ⓘ heeju0906@gmail.com; ⓘ EUROPEAN JOURNAL OF ONCOLOGY NURSING ⓘ EUR J ONCOL NURS ⓘ 1462-3889 1532-2122 74 SCIE;SSCI NURSING;ONCOLOGY ⓘ 2024 2.7 13.8 0 2025-05-07 ⓘ 0 0 Pain; Fatigue; Depression; Cognitive impairment; Symptom cluster; Cancer; Oncology; Stress; Cortisol; ACTH ⓘ PITUITARY-ADRENAL AXIS; SLEEP DISTURBANCE; AWAKENING RESPONSE; CYTOKINE GENES; SINGLE-ITEM; FATIGUE; DEPRESSION; PAIN; ASSOCIATION; RELIABILITY ⓘ ACTH; Cancer; Cognitive impairment; Cortisol; Depression; Fatigue; Oncology; Pain; Stress; Symptom cluster ⓘ Adrenocorticotropic Hormone; Adult; Aged; Cognitive Dysfunction; Cross-Sectional Studies; Depression; Fatigue; Female; Hematologic Neoplasms; Humans; Hydrocortisone; Male; Middle Aged; Pain; Sleep Wake Disorders; Stress, Psychological; corticotropin; hydrocortisone; adult; aged; blood; cognitive defect; complication; cross-sectional study; depression; etiology; fatigue; female; hematologic disease; human; male; mental stress; metabolism; middle aged; pain; psychology; sleep disorder ⓘ English 2025 2025-02 10.1016/j.ejon.2024.102728 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Role of PI3K/AKT signaling pathway during capacitation ⓘ Spermatozoa must undergo a complex maturation process within the female genital tract known as capacitation. This process entails the phosphorylation or dephosphorylation of various proteins, and multiple signaling pathways are recognized to play a role. The present study aims to identify alterations in the expression of proteins related to the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT) signaling pathway and assess sperm functions during capacitation. Mouse spermatozoa were incubated in a medium supplemented with bovine serum albumin to induce capacitation. Subsequently, we evaluated sperm motility, cell viability, capacitation status, and acrosome reaction. Consequently, we observed a significant increase in several kinematic parameters. Additionally, the capacitation status and acrosome reaction exhibited a time-dependent manner. Furthermore, we confirmed a significant increase in the phosphorylation of PI3K, PDK1, and p-AKT (Thr308), along with activation of PKA and tyrosine phosphorylation. These alterations in protein expression were found to correlate with capacitation status, acrosome reaction, and various kinematic parameters. Therefore, our findings show that the phosphorylation of PKA and PI3K/AKT pathway-related proteins during capacitation may plays a crucial role in regulating sperm function. These findings contribute to a better understanding of the molecular mechanisms and interactions of the PI3K/AKT signaling pathway in the capacitation process. ⓘ Lee, Woo-Jin; Jo, Jae-Hwan; Uwamahoro, Claudine; Jang, Seung-Ik; Jung, Eun-Ju; Bae, Jeong-Won; Moon, Joonho; Kim, Dae-Hyun; Yi, Jun Koo; Ha, Jae Jung; Oh, Dong Yep; Kwon, Woo-Sung ⓘ Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Chonnam Natl Univ, Dept Anim Sci, Gwangju 61186, South Korea; Hankyong Natl Univ, Sch Anim Life Convergence Sci, Anseong 17579, South Korea; Gyeongbuk Livestock Res Inst, Yeongju 36052, South Korea; Kyungpook Natl Univ, Res Inst Innovat Anim Sci, Sangju 37224, South Korea; Seoul Natl Univ Hosp, Seoul 03080, South Korea ⓘ Moon, Joonho/KFQ-2464-2024; Kwon, Woo-Sung/J-6731-2019; Bae, Jeong-Won/AAH-4932-2021 ⓘ 57377138800; 58346379700; 58844996200; 58346379800; 57377289200; 57211231093; 56410309500; 57211228843; 56182537200; 55848402300; 42861900800; 54383715800 ⓘ ody1234@korea.kr; wskwon@knu.ac.kr; ⓘ THERIOGENOLOGY ⓘ THERIOGENOLOGY ⓘ 0093-691X 1879-3231 235 SCIE REPRODUCTIVE BIOLOGY;VETERINARY SCIENCES ⓘ 2024 2.5 13.8 0 2025-05-07 ⓘ 0 0 Capacitation; Sperm function; PKA; PI3K/AKT pathway; Correlation analysis ⓘ TYROSINE PHOSPHORYLATION; ACROSOME REACTION; PHOSPHOINOSITIDE 3-KINASE; SPERM CAPACITATION; MAMMALIAN SPERM; KINASE; IDENTIFICATION; SPERMATOZOA; DOWNSTREAM; ACTIVATION ⓘ Capacitation; Correlation analysis; PI3K/AKT pathway; PKA; Sperm function ⓘ Acrosome Reaction; Animals; Male; Mice; Phosphatidylinositol 3-Kinase; Phosphatidylinositol 3-Kinases; Phosphorylation; Proto-Oncogene Proteins c-akt; Signal Transduction; Sperm Capacitation; Sperm Motility; Spermatozoa; phosphatidylinositol 3 kinase; protein kinase B; acrosome reaction; animal; drug effect; genetics; male; metabolism; mouse; phosphorylation; physiology; signal transduction; sperm capacitation; spermatozoon; spermatozoon motility ⓘ English 2025 2025-03-15 10.1016/j.theriogenology.2024.12.026 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhanced catalytic activity for emission control of CO and NH3 by solid-state impregnation of Ag on γ-Al2O3 support ⓘ While metallic Ag species are known for superior active sites for oxidation reactions of NH3 and CO compared to Ag oxides, achieving precise control over the surface Ag phase through the conventional wet method has been a significant challenge, primarily due to the strong metal-support interaction on the gamma-Al2O3 surface. This study unveiled that the chemical state of the Ag precursor before calcination is a crucial factor in determining these interactions, affecting the surface Ag phase. We found that the ionic state of Ag in aqueous solution, via a conventional preparation method, actively forms a strong bonding with surface hydroxyl groups on gamma-Al2O3, leading to the formation of well-dispersed Ag oxide species unfavorable for catalytic reactivity. By employing the solid-state impregnation method, we successfully suppressed this metal-support interaction, favoring the formation of metallic Ag nanoparticles. The resultant catalyst exhibited remarkable oxidation activities of CO or NH3, outperforming conventional impregnated catalysts. TEM and UV-vis spectroscopy confirmed that the Ag/ gamma-Al2O3 with solid-state impregnation exhibited pronounced metallic characteristics of Ag species, even at low Ag loadings. ⓘ Shin, Hyeonwoo; Byun, Sang Woo; Bae, Wo Bin; Choi, Wonseok; Ham, Dong Jin; Kwon, Hyuk Jae; Kim, Young Jin; Kang, Sung Bong ⓘ Gwangju Inst Sci & Technol, Dept Environm & Energy Engn, 123 Cheomdan Gwagiro, Gwangju 61005, South Korea; Rowan Univ, Dept Chem Engn, Glassboro, NJ 08028 USA; Samsung Elect Co Ltd, SAIT Samsung Adv Inst Technol, ASRC Air Sci Res Ctr, 130 Samsung Ro, Suwon 16678, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Res Ctr Innovat Energy & Carbon Optimized Synth Ch, 261 Cheomdan Gwagiro, Gwangju 61005, South Korea ⓘ Kim, Young-jin/GSD-3168-2022 ⓘ 57654657000; 57481416600; 57218296461; 59768886600; 21738986600; 57188536178; 59054565400; 59969495200 ⓘ sbkang@gist.ac.kr; ⓘ JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING ⓘ J ENVIRON CHEM ENG ⓘ 2213-2929 2213-3437 13 3 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 7.2 14.0 N/A ⓘ 0 0 Solid-state impregnation; CO oxidation; Ag phase; NH3 oxidation ⓘ AG/AL2O3 CATALYST; GAMMA-ALUMINA; OXIDATION; REDUCTION; NOX; METHANE; WATER ⓘ Ag phase; Ag/γ-Al<sub>2</sub>O<sub>3</sub>; CO oxidation; NH<sub>3</sub>oxidation; Solid-state impregnation ⓘ Ag phase; Ag/γ-al2O3; CO oxidation; Emissions control; Enhanced catalytic activity; Metallics; NH 3; NH3oxidation; Solid-state impregnation; γ Al2O3; Nanocatalysts ⓘ English 2025 2025-06 10.1016/j.jece.2025.116463 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhanced catalytic activity of rice husk biochar for antibiotics degradation: Synergistic effects of copolymerization and mineral removal ⓘ Effective utilization of rice husk (RH) biomass is essential to mitigate the environmental issues associated with it. Though RH biochar has been widely studied as a metal free carbon catalyst for persulfate activation, its performance is often limited by low active site density. In this study, we propose a two-step strategy to enhance RH biochar's active site density through copolymerization, and mineral etching process. This design strategy enables the creation of new metal-free active centers and enhances the exposure of existing active sites on the RH surface, thereby effectively overcoming the limitations of metal leaching in metal/carbon composite systems. The prepared RH biochar/copolymer composite catalyst displayed excellent tetracycline (TC) removal efficiency with peroxydisulfate. Composition optimization results showed RH biochar with 33 wt% of copolymer derived carbon has high TC degradation efficiency. Furthermore, the removal of mineral impurities significantly enhanced the catalytic efficiency, enabling a 50 % reduction in the catalyst concentration while maintaining the same level of degradation performance. An increased specific surface area of the catalyst boosts the catalytic efficiency. Electron spin resonance spectroscopy (ESR), scavenging experiments, and electrochemical studies confirmed that tetracycline degradation occurs mainly through electron transfer pathway. The composite also displayed a satisfactory TC degradation performance with anions and in real groundwater conditions. This study introduces a novel strategy for creating metal-free active centers on RH biochar, offering a promising solution for real-world water treatment applications. ⓘ Silambarasan, Krishnamoorthy; Kumar, Alam Venugopal Narendra; Shin, Won Sik ⓘ Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea ⓘ ⓘ 58045774500; 39262149400; 23019870800 ⓘ wshin@knu.ac.kr; ⓘ JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING ⓘ J ENVIRON CHEM ENG ⓘ 2213-2929 2213-3437 13 3 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 7.2 14.0 N/A ⓘ 0 0 Nitrogen doped carbon; Rice husk biochar; Tetracycline; Water treatment; Persulfate activation; Copolymer ⓘ ACTIVATED CARBON; PERSULFATE; TRANSFORMATION ⓘ Copolymer; Nitrogen doped carbon; Persulfate activation; Rice husk biochar; Tetracycline; Water treatment ⓘ Copolymerization; Active center; Active site density; Copolymerisation; Metal free; Nitrogen-doped carbons; Performance; Persulfate activations; Rice husk; Rice husk biochar; Tetracycline; Electron spin resonance spectroscopy ⓘ English 2025 2025-06 10.1016/j.jece.2025.116560 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Exploratory investigation of the correlation between microplastics and breast cancer: Polystyrene-derived microplastics promote cell proliferation via estrogenic endocrine disruption ⓘ Polystyrene-derived microplastics (PS-MP) are one of the most important environmental problems in modern society and are associated with various chronic disorders. Previous studies have shown that PS-MP exerts estrogenic effects on aquatic organisms. This research indicates that PS-MP may function as an endocrinedisrupting chemical and a risk factor for estrogen-related diseases, such as breast cancer. However, the carcinogenic potential of PS-MPs in breast cancer has not been studied extensively. Therefore, in the present study, we aimed to elucidate the effects of PS-MP on human breast cancer cells. Estrogen receptor (ER)-positive (MCF-7) and ER-negative (MDA-MB-231) human breast cancer cells were exposed to low and high concentrations of PSMP for 4 weeks. MCF-7 cells exposed to PS-MP exhibited significantly increased cell viability, whereas MDA-MB231 cells showed no change. Subsequent in vitro and in vivo experiments demonstrated that PS-MP-stimulated MCF-7 cells significantly increased non-genomic ER signaling pathways and tumor growth in mice. Moreover, the ER-knockdown MCF-7 cells were not affected by PS-MP simulation. Our results demonstrate that PS-MP stimulation promotes the malignant transformation of human breast cancer cells via the ER signaling pathway. Considering the emerging concerns regarding PS-MP pollution worldwide, these data provide novel insights into the potential carcinogenic risk of PS-MP to human breast cancer. ⓘ Lee, Seoung-Woo; Kim, Hee-Yeon; Jang, Soyoung; Kim, Wansoo; Kim, Choonok; Lee, Jiyeon; Ryoo, Zae Young; Han, Jee Eun; Baek, Su-Min; Park, Jin-Kyu; Hwang, Jun-Seong; Lee, Sung-Jun; Lee, Young-Jae; Park, Song; Han, Sehyeon; Choi, Seong-Kyoon ⓘ Daegu Gyeongbuk Inst Sci & Technol DGIST, Div Biomed Technol, Daegu, South Korea; DGIST, Core Prot Resources Ctr, Daegu, South Korea; Kyungpook Natl Univ, Coll Vet Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu 41566, South Korea; SilicoPharm Inc, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, Daegu 41566, South Korea; J INTS BIO Inc, Seoul, South Korea; Gyeongsang Natl Univ, Inst Agr & Life Sci IALS, Jinju 52828, South Korea; Gyeongsang Natl Univ, Div Anim Sci, Jinju 52828, South Korea; Gyeongsang Natl Univ, Inst Smart Farm Res Ctr, Jinju 52828, South Korea; Honam Univ, Coll Hlth Sci, Dept Compan Anim Ind, Gwangju, South Korea ⓘ RYOO, ZAEYOUNG/AAQ-1573-2020 ⓘ 57218827581; 58368914700; 57139360300; 57352897900; 59195731100; 59196567700; 16937104900; 57214671240; 57207938426; 35213723500; 57189033977; 59417484200; 57199021765; 57139047900; 57210915063; 55505432500 ⓘ cristaling9816@gnu.ac.kr; han382@honam.ac.kr; cskbest@dgist.ac.kr; ⓘ JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING ⓘ J ENVIRON CHEM ENG ⓘ 2213-2929 2213-3437 13 2 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 7.2 14.0 0 2025-05-07 ⓘ 0 0 Breast cancer; Carcinogen; Estrogen; Polystyrene; Microplastic ⓘ DIETHYLSTILBESTROL; MOTHERS ⓘ Breast cancer; Carcinogen; Estrogen; Microplastic; Polystyrene ⓘ Breast Cancer; Cell-be; Cell/B.E; Cell/BE; Estrogen receptor; Human breast cancer cells; MCF-7 cells; MDA-MB-231; Microplastics; Oestrogens; Lung cancer ⓘ English 2025 2025-04 10.1016/j.jece.2025.115473 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Low-temperature catalytic CO2 methanation over nickel supported on praseodymium oxide ⓘ Nickel (Ni)-based catalysts are widely used for CO2 methanation due to their cost-effectiveness compared to noble metals and high efficiency. However, their catalytic performance at low temperatures remains a significant challenge, primarily due to the limited activation of CO2. This study reveals that the Ni supported on praseodymium oxide (PrOx) significantly enhanced low-temperature CO2 methanation activity. This enhancement was primarily attributed to the dual role of PrOx: promoting CO2 activation and modifying the reducibility of Ni active sites. PrOx facilitated the formation of oxygen vacancies (Ov) through the valence state transition (Pr3+ Pr4+), providing electron donor sites for direct CO2 dissociation (CO2 -> CO + O*). Furthermore, metal-support interaction (MSI) between Ni and PrOx enhanced the reducibility of Ni2+ to Ni0 , inducing a higher density of hydrogen activation sites for the hydrogenation of CO2. The integration of these properties induced a high efficiency of the CO2 methanation pathway by enhancing reactant activation efficiency. These findings demonstrate that the synergistic interaction between Ni and PrOx enhances CO2 methanation by simultaneously improving Ni site reducibility and providing abundant oxygen vacancies for CO2 activation, indicating PrOx as a highly effective support material for low-temperature CO2 methanation catalysts. ⓘ Ju, Yanggeun; Bae, Dasol; Kim, Minkyu; Ryu, Taekyung; Hazlett, Melanie J.; Min, Haehyun; Park, Junseo; Kim, Young Jin; Kang, Sung Bong ⓘ Gwangju Inst Sci & Technol, Dept Environm & Energy Engn, Gwangju 61005, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Univ Wisconsin Madison, Dept Chem, Madison, WI 53706 USA; Concordia Univ, Gina Cody Sch Engn & Comp Sci, Chem & Mat Engn, Montreal, PQ H4B1R6, Canada; State Univ New York, Dept Chem Engn, Coll Environm Sci & Forestry, Syracuse, NY 13210 USA; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Res Ctr Innovat Energy & Carbon Optimized Synth Ch, Gwangju 61005, South Korea ⓘ Hazlett, Melanie/G-5799-2018 ⓘ 57716869100; 57238971300; 57116750000; 56381092300; 56849465900; 57367334300; 59681867800; 59054565400; 59969495200 ⓘ sbkang@gist.ac.kr; ⓘ JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING ⓘ J ENVIRON CHEM ENG ⓘ 2213-2929 2213-3437 13 2 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 7.2 14.0 0 2025-05-07 ⓘ 0 0 CO2 methanation; Ni-based catalyst; PrOx support; Oxygen vacancies (Ov); CO2 activation; Metal-support interaction (MSI) ⓘ UNSTABLE LATTICE OXYGEN; DESORPTION; PROMOTION ⓘ CO<sub>2</sub> activation; CO<sub>2</sub> methanation; Metal-support interaction (MSI); Ni-based catalyst; Oxygen vacancies (O<sub>v</sub>); PrO<sub>x</sub> support ⓘ Hydrogenation; Methanation; Nickel; Praseodymium compounds; CO2 activation; CO2 methanation; Lows-temperatures; Metal-support interaction; Metal-support interactions; Nickel-based catalyst; Oxide supports; Oxygen vacancy; Praseodymium oxide support; Praseodymium oxides; Cost effectiveness ⓘ English 2025 2025-04 10.1016/j.jece.2025.116129 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Reaction mechanism and kinetics on the methanolysis-esterification-lactonization of α-phellandrene-derived cyclic acid anhydride ⓘ Alkyl bicyclo[2.2.2]octanes (ABCOs) have been designed as high-energy-density hydrocarbons for bio-aviation fuel. In the proposed ABCO synthesis route from alpha-phellandrene and maleic anhydride, ABCOs yield by hydrotreating depends on the precursor type, and bicyclic dimethyl ester 4 was the most promising candidate, showing the highest yield. However, there has been little discussion about the mechanism and kinetics of dimethyl ester 4 preparation reaction from acid anhydride 3 wherein lactone methyl ester 5 is also produced as a by-product. In this context, herein, we focused on the methanolysis-esterification-lactonization of acid anhydride 3 with methanol in the presence of sulfuric acid. Two different reaction mechanisms (competitive vs. consecutive) were discussed and only consecutive mechanism was favored on the basis of experimental results. In this mechanism, acid anhydride 3 is initially converted to dimethyl ester 4, followed by the formation of lactone methyl ester 5. The direct lactonization of dimethyl ester 4 can be rationalized by stereoelectronic considerations in the cleavage of cyclic hemiorthoester 10. Based on this reaction mechanism, a kinetic model comprising of two consecutive pseudo-first-order-kinetic reactions (methanolysis-esterification (k1,obs) and lactonization (k2,obs)) was proposed to elucidate this complex process. Through this kinetic model, the activation parameters were determined; the activation energy (Ea, 59.1 kJ center dot mol-1), preexponential factor (A, 1.15 x 107 min-1), activation enthalphy (Delta H double dagger, 56.5 kJ center dot mol-1), and activation entropy (Delta S double dagger, -152.5 J center dot mol-1 center dot K-1) for the methanolysis-esterification; Ea (100.2 kJ center dot mol-1), A (1.80 x 1012 min-1), Delta H double dagger(97.6 kJ center dot mol-1), and Delta S double dagger (-53.1 J center dot mol-1 center dot K-1) for the lactonization. Additionally, the reaction orders of apparent rate constants (k1,obs and k2,obs) depending on sulfuric acid concentration were determined as 0.54 and 0.78, respectively. Using these parameters, a product prediction model was developed based on reaction temperature and sulfuric acid concentration. The model suggested optimal conditions to achieve a 90 % yield of dimethyl ester 4: a sulfuric acid concentration of 0.3 mol/L at 40 degrees C for 18.8 h. This prediction was experimentally validated. ⓘ Cho, Seong-Min; Choi, Won-Sil; Cho, Young-Min; Lee, Soo Min; Koo, Bonwook; Choi, In-Gyu ⓘ North Carolina State Univ, Dept Forest Biomat, 2820 Faucette Dr, Raleigh, NC 27695 USA; Seoul Natl Univ, Natl Instrumentat Ctr Environm Management, 1 Gwanak Ro, Seoul 08826, South Korea; Seoul Natl Univ, Dept Agr Forestry & Bioresources, 1 Gwanak Ro, Seoul 08826, South Korea; Natl Inst Forest Sci, Forest Ind Mat Div, Forest Prod & Ind Dept, Seoul 02455, South Korea; Kyungpook Natl Univ, Sch Forestry Sci & Landscape Architecture, 80 Daehak Ro, Daegu 41566, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, 1 Gwanak ro, Seoul 08826, South Korea ⓘ Choi, In-Gyu/AAS-1362-2020; Cho, Seong-Min/AAI-3007-2020 ⓘ 57094356900; 55629791200; 57217245658; 59057619400; 59507457600; 7401471763 ⓘ cingyu@snu.ac.kr; ⓘ JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING ⓘ J ENVIRON CHEM ENG ⓘ 2213-2929 2213-3437 13 1 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 7.2 14.0 0 2025-05-07 ⓘ 0 0 Alkyl bicyclo[2.2.2]octanes; Methanolysis; Esterification; Lactonization; Stereoelectronic effects; Kinetics ⓘ OXIDATIVE LACTONIZATION; ORTHO-ESTERS; HYDROLYSIS ⓘ Alkyl bicyclo[2.2.2]octanes; Esterification; Kinetics; Lactonization; Methanolysis; Stereoelectronic effects ⓘ Catalytic cracking; Entropy; Fatty acid methyl ester; Temperature; Acid anhydride; Acid concentrations; Alkyl bicyclo[2.2.2]octane; Bicyclo[2.2.2]octane; Dimethyl esters; Lactonization; Mechanism and kinetics; Methanolysis; Reaction mechanism; Stereoelectronic effect; Activation energy ⓘ English 2025 2025-02 10.1016/j.jece.2025.115383 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Revolutionizing anode-free batteries with holey graphene interlayers: Achieving uniform lithium deposition and long-term stability ⓘ The expansion of the electric vehicles (EVs) market has highlighted the need to develop batteries with high energy density and efficiency with stable performance. To address this need, researchers have proposed anodefree batteries, a promising solution that reduces battery volume by eliminating the need for anodes. However, anode-free batteries encounter challenges such as reduced cycle life and compromised cycling stability, mainly due to a shortage of lithium sources and the issue of lithium dendritic growth caused by irregular Li deposition. A critical concern is the formation of an unstable Solid Electrolyte Interphase (SEI) layer on current collectors, prompting numerous studies to address this challenge. This study proposes a novel approach involving the coating of copper (Cu) current collectors with holey graphene (HG) to enhance the stability of anode-free batteries. HG, known for its abundance of holes on the basal plane and a lower Fermi level compared with conventional graphene (GR) due to defects, proves effective in inhibiting electron transfer to the lowest unoccupied molecular orbital (LUMO) of the electrolyte. This inhibition prevents ongoing electrolyte decomposition and supports the formation of a stable SEI. In addition, HG suppresses lithium dendritic growth by promoting uniform Li deposition. This approach is attributed to the thin and uniform SEI structure initially formed on the surface of the HG. In testing anode-free batteries using HG, GR, and uncoated Cu, the HG-based anode-free full cell exhibited remarkable performance. It demonstrated a high coulombic efficiency (CE) of 99.6 % during 200 cycles, even without the inclusion of Li metal. Moreover, capacity characteristics of the full cell with the HG surpass those of a full cell using GR. ⓘ Jang, Eunbin; Park, Seungjin; Lee, Jemin; Kim, Patrick Joohyun; Yoo, Jeeyoung ⓘ Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea ⓘ Yoo, Jeeyoung/AAH-1359-2019 ⓘ 57837176500; 59327034000; 58959227800; 57195611779; 56046607500 ⓘ pjkim@knu.ac.kr; jyoo@knu.ac.kr; ⓘ JOURNAL OF ENERGY STORAGE ⓘ J ENERGY STORAGE ⓘ 2352-152X 2352-1538 115 SCIE ENERGY & FUELS ⓘ 2024 9.8 14.0 0 2025-05-07 ⓘ 0 0 Anode free battery; Artificial interface; Holey graphene; Fermi level; Solid electrolyte interphase ⓘ HIGH-ENERGY; METAL ANODE; LAYER; SPECTROSCOPY; MORPHOLOGY ⓘ Anode free battery; Artificial interface; Fermi level; Holey graphene; Solid electrolyte interphase ⓘ Lithium batteries; Anode free battery; Artificial interfaces; Current-collector; Dendritic growth; Graphenes; Higher energy density; Holey graphene; Li deposition; Long term stability; Solid electrolyte interphase; Anodes ⓘ English 2025 2025-04-15 10.1016/j.est.2025.115974 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Phosphine as a possible alternative to methyl bromide for the phytosanitary treatment of wood products ⓘ Phosphine (PH3) has gained momentum as a phytosanitary treatment to control quarantine pests in exported wood products. Originally used as a grain fumigant, its use increased after methyl bromide was banned for its ozone-depleting properties. While the effectiveness of PH3 against grain pests is well-established, its efficacy for wood products requires review due to growing adoption. We observed insufficient evidence supporting PH3 as a broad-spectrum quarantine treatment for wood products from peer-reviewed/gray literature and international groups. We assessed 41 research articles covering 29 insect species, 1 nematode, and 11 fungi, and observed that while PH3 is effective against some forest insects, it generally fails to meet quarantine treatment standards and is ineffective against nematodes and fungi. Our analysis highlights concerns over the effectiveness of PH3 as a broad-spectrum treatment for wood products. Many studies lack the quality needed to meet contemporary standards. We strongly recommend that National Plant Protection Organizations review the efficacy data supporting PH3 use for wood products to strengthen biosecurity systems. ⓘ Hall, Matthew K.
