○ Article ⓘ Cost-of-illness changes before and after the diagnosis of systemic lupus erythematosus: a nationwide, population-based observational study in Korea ⓘ Objectives: To estimate the direct healthcare cost progression from before to after systemic lupus erythematosus (SLE) diagnosis and to compare healthcare costs by disease severity. Methods: Patients with incident SLE diagnosed between 2008 and 2018 were identified from the Korean National Health Insurance database. Annual direct healthcare costs for 5 years before and after SLE were estimated and compared with those of age-, sex- and calendar month-matched (1:4) controls, without SLE. Direct healthcare costs were compared by disease severity of SLE using regression analysis. Results: Among 11 173 patients with SLE and 45 500 subjects without SLE, annual direct healthcare costs per person increased in the year before SLE diagnosis and peaked in the first year after diagnosis. They were 7.7-fold greater in the SLE patients than in the subjects without SLE ($5871 vs $759). Severe SLE was associated with 3.284-fold (95% CI: 3.075, 3.507) higher annual costs than mild SLE during the year after diagnosis. Older age (age 60-79 years), lupus nephritis, interstitial lung diseases, and comorbidities such as avascular necrosis and chronic kidney disease were associated with higher annual direct healthcare costs (times [95% CI]) in the first year after diagnosis: age 60-69: 1.119 (1.034, 1.211); age 70-79: 1.470 (1.342, 1.611); lupus nephritis: 1.794 (1.711, 1.881); interstitial lung diseases: 1.435 (1.258, 1.638); avascular necrosis: 6.208 (4.541, 8.487); and chronic kidney disease: 1.858 (1.673, 2.064). Conclusion: Patients with SLE incurred significantly higher direct healthcare costs than subjects without SLE during the first year after diagnosis. Disease severity, older age, major organ involvements and comorbidities were associated with increased healthcare costs. © 2023 The Author(s). ⓘ Kim, Hyoungyoung; Jang, Eun Jin; Cho, Soo-Kyung; Han, Jung-Yong; Jeon, Yena; Jung, Sun-Young; Sung, Yoon-Kyoung ⓘ Department of Rheumatology, Hanyang University Hospital for Rheumatic Diseases, Seoul, South Korea, Hanyang University Institute for Rheumatology Research, Seoul, South Korea; Department of Information Statistics, Andong National University, Andong, South Korea; Department of Rheumatology, Hanyang University Hospital for Rheumatic Diseases, Seoul, South Korea, Hanyang University Institute for Rheumatology Research, Seoul, South Korea; Department of Rheumatology, Hanyang University Hospital for Rheumatic Diseases, Seoul, South Korea, Hanyang University Institute for Rheumatology Research, Seoul, South Korea; Department of Statistics, Kyungpook National University, Daegu, South Korea; College of Pharmacy, Chung-Ang University, Seoul, South Korea; Department of Rheumatology, Hanyang University Hospital for Rheumatic Diseases, Seoul, South Korea, Hanyang University Institute for Rheumatology Research, Seoul, South Korea ⓘ ⓘ 57202108695; 37861741600; 35185890800; 57220065429; 57209909350; 57207445502; 15754508900 ⓘ sungyk@hanyang.ac.kr; ⓘ Rheumatology ⓘ RHEUMATOLOGY ⓘ 1462-0324 1462-0332 64 1 SCIE RHEUMATOLOGY ⓘ 2024 4.4 14.7 5.25 2025-05-07 ⓘ 1 ⓘ ⓘ disease severity; healthcare cost; systemic lupus erythematosus ⓘ Adult; Aged; Comorbidity; Cost of Illness; Female; Health Care Costs; Humans; Lupus Erythematosus, Systemic; Male; Middle Aged; Republic of Korea; Severity of Illness Index; Young Adult; azathioprine; cyclophosphamide; cyclosporine; glucocorticoid; hydroxychloroquine; leflunomide; methotrexate; mizoribine; mycophenolate mofetil; nonsteroid antiinflammatory agent; tacrolimus; adolescent; adult; age; aged; Article; avascular necrosis; child; chronic kidney failure; comorbidity; comparative study; controlled study; cost of illness; data base; disease severity; female; health care cost; human; interstitial lung disease; lupus erythematosus nephritis; major clinical study; male; middle aged; national health insurance; population research; South Korea; systemic lupus erythematosus; diagnosis; economics; epidemiology; severity of illness index; systemic lupus erythematosus; young adult ⓘ English Final 2025 10.1093/rheumatology/kead664 ⓘ 바로가기 바로가기 바로가기
○ Article ⓘ Dome-Structure Array from Pre-Strained Extendable Mesh for Tactile Sensing Without Crosstalk and Lateral Strain Interference ⓘ Flexible tactile sensors have received significant attention for use in wearable applications such as robotics, human-machine interfaces, and health monitoring. However, conventional tactile sensors face challenges in accurately measuring pressure because vertical deformation is induced by Poisson's ratio in situations where lateral strain is applied. This study shows a strain-insensitive flexible tactile sensor array without the crosstalk effect using a highly stretchable mesh. This sensor is fabricated by assembling a sensing layer in which sensing cells form in each hole of an elastomer mesh and liquid-metal-based stretchable electrode layers. Stretching deforms the soft mesh layer with little effect on the rigid sensing cell array, which results in the sensor being insensitive to uniaxial strain. In addition, each sensing cell is formed in a dome shape, which resulted in a sensor exhibiting high sensitivity (7.80 kPa−1) over a wide sensing range (<160 kPa). The proposed design also allows each sensing cell to be electrically separated, enabling the pressure measurements without cell-to-cell crosstalk. Based on these characteristics, strain-insensitive pressure monitoring is demonstrated to prevent carpal/cubital tunnel syndrome by attaching the device to the joints, which suggests its potential application in healthcare. © 2025 Wiley-VCH GmbH. ⓘ Bae, Kyubin; Kim, Minhyeong; Sim, Sangjun; Kang, Yunsung; Kim, Jongbaeg ⓘ School of Mechanical Engineering, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea; School of Mechanical Engineering, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea; School of Mechanical Engineering, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea; Department of Precision Mechanical Engineering, Kyungpook National University, 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea, Convergence Research Center of Mechanical and Chemical Engineering (CRCMCE), Kyungpook National University, 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea; School of Mechanical Engineering, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea ⓘ ⓘ 57216338035; 57843256500; 57216353900; 57193683552; 55881484100 ⓘ kimjb@yonsei.ac.kr; ⓘ Small Methods ⓘ SMALL METHODS ⓘ 2366-9608 2366-9608 SCIE CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY ⓘ 2024 9.1 14.7 0 2025-05-07 ⓘ 1 ⓘ ⓘ crosstalk-free; healthcare monitoring; stretchable sensors; tactile sensor arrays ⓘ Crosstalk; Mesh generation; Pressure measurement; Structural health monitoring; Crosstalk-free; Dome structure; Flexible tactile sensors; Healthcare monitoring; Human Machine Interface; Lateral strain; Stretchable sensor; Tactile sensing; Tactile sensor array; Wearable applications; Domes ⓘ English Article in press 2025 10.1002/smtd.202401730 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Myricitrin Alleviates Hypercholesterolemia and Non-Alcoholic Fatty Liver Disease in High Cholesterol Diet-Fed Mice ⓘ Background/Objectives: This research investigated the effects of myricitrin on hypercholesterolemia and non-alcoholic fatty liver disease (NAFLD) in mice given a high-cholesterol diet (HCD). Methods: C57BL/6J mice were maintained for 20 weeks on an HCD with or without myricitrin. Results: Myricitrin had no impact on the food consumption, body weight, or plasma triglyceride concentrations. However, myricitrin-supplemented mice had lower plasma total cholesterol (TC) concentrations and LDL + VLDL-cholesterol/TC proportion, and higher HDL-cholesterol/TC proportion than control mice, which resulted in a markedly decreased atherogenic index. Moreover, the levels of plasma C-reactive protein, oxidized LDL, lipoprotein(a), and plasminogen activator inhibitor-1, which are indicators for cardiovascular disease (CVD), were reduced, while levels of plasma paraoxonase, a cardioprotective enzyme, were greater in myricitrin-supplemented mice than in control mice. Myricitrin also meaningfully reduced liver weight and hepatic cholesterol content, and slightly alleviated fatty liver and fibrosis caused by an HCD. The plasma and hepatic cholesterol-lowering effects of myricitrin were partly associated with decreased activities of hepatic 3-hydroxy-3-methylglutaryl-CoA reductase and acyl-CoA:cholesterol acyltransferase, which are involved in cholesterol synthesis and esterification, respectively, as well as mRNA expression. Myricitrin also altered other hepatic genes implicated in cholesterol homeostasis, including the downregulation of SREBP2 and ABCA1 mRNA expression and the upregulation of LDLR mRNA expression. Moreover, myricitrin decreased TBARS levels in the liver and erythrocytes by activating antioxidant enzymes (SOD and catalase). Conclusions: These results indicate that dietary myricitrin may offer therapeutic benefits for HCD-caused hypercholesterolemia and NAFLD, and may help reduce CVD risk. ⓘ Kim, Young-Je; Park, Sojeong; Kim, Hwicheol; Kim, Sang Ryong; Jung, Un Ju ⓘ Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Food Sci & Nutr, 45 Yongso Ro, Busan 48513, South Korea; Kyungpook Natl Univ, Sch Life Sci, Daegu 41566, South Korea ⓘ ⓘ 55571346800; 59552240200; 59551696100; 56486163800; 7007119425 ⓘ breezy750@naver.com; impark-sj@naver.com; k423897@naver.com; srk75@knu.ac.kr; jungunju@pknu.ac.kr; ⓘ NUTRIENTS ⓘ NUTRIENTS ⓘ 2072-6643 17 3 SCIE NUTRITION & DIETETICS ⓘ 2024 5 14.7 0 2025-05-07 ⓘ 1 1 myricitrin; high-cholesterol diet; hypercholesterolemia; non-alcoholic fatty liver disease ⓘ LOW-DENSITY-LIPOPROTEIN; OXIDATIVE STRESS; OXIDIZED LDL; RAT-LIVER; EXPRESSION; PARAOXONASE-1; ACCUMULATION; METABOLISM; APOPTOSIS; SEVERITY ⓘ high-cholesterol diet; hypercholesterolemia; myricitrin; non-alcoholic fatty liver disease ⓘ Animals; Anticholesteremic Agents; Cholesterol; Cholesterol, Dietary; Diet, High-Fat; Disease Models, Animal; Flavonoids; Hypercholesterolemia; Liver; Male; Mice; Mice, Inbred C57BL; Non-alcoholic Fatty Liver Disease; aryldialkylphosphatase; C reactive protein; catalase; cholesterol; high density lipoprotein; high density lipoprotein cholesterol; hydroxymethylglutaryl coenzyme A reductase; lipoprotein A; low density lipoprotein; oxidized low density lipoprotein; plasminogen activator inhibitor 1; sterol o acyltransferase; sterol regulatory element binding protein 2; superoxide dismutase; thiobarbituric acid reactive substance; triacylglycerol; very low density lipoprotein cholesterol; cholesterol; flavonoid; hypocholesterolemic agent; myricitrin; animal experiment; animal model; animal tissue; Article; body weight; cardiovascular disease; cholesterol blood level; cholesterol diet; cholesterol metabolism; cholesterol synthesis; controlled study; down regulation; food intake; gene expression; hemoglobin determination; histology; hypercholesterolemia; lipid liver level; lipid peroxidation; liver weight; male; mouse; mRNA expression level; nonalcoholic fatty liver; nonhuman; triacylglycerol blood level; upregulation; adverse event; animal; blood; C57BL mouse; cholesterol intake; disease model; drug effect; drug therapy; etiology; lipid diet; liver; metabolism ⓘ English 2025 2025-02 10.3390/nu17030415 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Sericin's Potential in Osteoporosis Management: The Roles of L-Serine and D-Serine in Bone Metabolism Regulation ⓘ Background: Osteoporosis is a bone remodeling disease characterized by an imbalance between bone formation and resorption, leading to bone fragility. Current treatments focus on bone resorption suppression but often have adverse effects. This study aimed to explore the potential of sericin, a silkworm-derived protein, as a dual-action therapeutic agent that enhances bone formation through its component L-serine and inhibits bone resorption via D-serine, which is derived from L-serine by the action of serine racemase. Methods: Cellular experiments were conducted to evaluate the effects of L-serine on osteoblast differentiation and D-serine on osteoclast inhibition. Serum levels of D-serine were measured following sericin administration in an osteoporosis animal model. mu-CT analysis assessed trabecular and cortical bone quality, and bone-related protein expression was analyzed using immunoprecipitation-based high-performance liquid chromatography (IP-HPLC). Results: L-serine significantly upregulated osteogenic markers, including alkaline phosphatase (ALP), Runx2, osterix, and Col1a1, in osteoblasts (p < 0.05). D-serine inhibited osteoclast activation by suppressing cathepsin K expression (p < 0.001). Sericin feeding elevated serum D-serine levels (p < 0.001) and upregulated bone-related proteins such as BMP-2, osterix, and Runx2. Micro-computed tomography (mu-CT) analysis revealed significant improvements in trabecular bone parameters in the OVX-sericin group, including increased trabecular bone volume (Tb.BV/TV; p < 0.05) and reduced trabecular separation (Tb.Sp; p < 0.05), compared to the OVX and OVX-amino acid groups. Cortical bone parameters, including cortical bone volume (Ct.BV/TV) and cortical area (Ct.Ar), did not significantly differ among OVX groups, but all were lower than in the sham group (p < 0.05). Conclusions: This study demonstrates that sericin modulates bone metabolism by enhancing osteoblast activity through L-serine and inhibiting osteoclastogenesis via D-serine. Sericin supplementation improved trabecular bone mass in an osteoporosis model, highlighting its potential for bone health. ⓘ Kim, Jwa-Young; Che, Xiangguo; Kim, Shihyun; Choi, Jongho; Lee, Joon Ha; Lee, Ji-Hae; Kweon, Haeyong; Lee, Suk Keun; Choi, Je-Yong; Kim, Seong-Gon ⓘ Hallym Univ, Kangnam Sacred Heart Hosp, Med Ctr, Dept Oral & Maxillofacial Surg, 1 Singil Ro, Seoul 07441, South Korea; Kyungpook Natl Univ, Sch Med, Cell & Matrix Res Inst, Dept Biochem & Cell Biol, Daegu 41944, South Korea; Gangneung Wonju Natl Univ, Coll Dent, Dept Oral Pathol, 7 Jukheon Gil, Gangneung Si 25457, Gangwon Do, South Korea; Rural Dev Adm, Natl Inst Agr Sci, Ind Insect & Sericulture Div, Wanju 55365, South Korea; Inst Hydrogen Magnet React Gene Regulat, Daejeon 34140, South Korea; Gangneung Wonju Natl Univ, Coll Dent, Dept Oral & Maxillofacial Surg, 7 Jukheon Gil, Gangneung Si 25457, South Korea ⓘ Choi, Je-Yong/AAR-7334-2021; Kim, Sung-Soo/ABD-3771-2021 ⓘ 35368445600; 54792660600; 57874184700; 59039628300; 37960965000; 56046902700; 7004390708; 16417454200; 7501391068; 27171913700 ⓘ jwayoung@hanmail.net; xiangguo0622@naver.com; shihyun7372@hanmail.net; jhchoi@gwnu.ac.kr; coover@korea.kr; jihae@korea.kr; hykweon@korea.kr; sukkeunlee@hanmail.net; jechoi@knu.ac.kr; kimsg@gwnu.ac.kr; ⓘ NUTRIENTS ⓘ NUTRIENTS ⓘ 2072-6643 17 3 SCIE NUTRITION & DIETETICS ⓘ 2024 5 14.7 0 2025-05-07 ⓘ 1 1 sericin; L-serine; D-serine; osteoporosis; bone metabolism; osteoblast; osteoclast ⓘ PREVENTION ⓘ bone metabolism; D-serine; L-serine; osteoblast; osteoclast; osteoporosis; sericin ⓘ Animals; Bone and Bones; Bone Density; Bone Remodeling; Bone Resorption; Cell Differentiation; Disease Models, Animal; Female; Humans; Mice; Osteoblasts; Osteoclasts; Osteogenesis; Osteoporosis; Sericins; Serine; X-Ray Microtomography; alkaline phosphatase; amino acid; bone morphogenetic protein 2; cathepsin K; collagen type I alpha 1 chain; dextro serine; messenger RNA; racemase; sericin; serine; transcription factor osterix; transcription factor RUNX2; sericin; serine; adult; animal cell; animal experiment; animal model; animal tissue; Article; blood level; Bombyx mori; bone fragility; bone mass; bone metabolism; bone quality; bone remodeling; bone volume; cell differentiation; controlled study; cortical bone; drug mechanism; female; gene expression level; high performance liquid chromatography; immunoprecipitation; metabolic regulation; micro-computed tomography; mRNA expression level; nonhuman; oophorectomy; ossification; osteoblast; osteoclast; osteoclast activity; osteoclastogenesis; osteolysis; osteoporosis; protein expression level; rat; trabecular bone; trabecular separation; upregulation; animal; bone; bone density; bone development; disease model; drug effect; drug therapy; human; metabolism; mouse; osteoblast; osteoclast; osteoporosis ⓘ English 2025 2025-02 10.3390/nu17030574 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Ultrafast Synthesis of Hard Carbon Anodes for Sodium-ion Batteries: An Intense-Pulsed-Light-Assisted Approach to Photothermal Carbonization of Polymer/Carbon Nanotube Composite Films ⓘ The conventional carbonization process for synthesizing hard carbons (HCs) requires high-temperature furnace operations exceeding 1000 °C, leading to excessive energy consumption and lengthy processing times, which necessitates the exploration of more efficient synthesis methods. This study demonstrates the rapid preparation of HC anodes using intense pulsed light (IPL)-assisted photothermal carbonization without the prolonged and complex operations typical of traditional carbonization methods. A composite film of microcrystalline cellulose (MCC) and single-walled carbon nanotubes (SWCNTs) is carbonized at high temperatures in less than 1 min. The SWCNTs efficiently absorbed light energy, enabling ultrafast heating and eliminating the need for prolonged, high-energy furnace-based processes. The IPL-assisted HC anodes exhibited excellent electrochemical performance, with an initial desodiation capacity of 260.4 mAh g⁻¹anode and 97.5% capacity retention after 200 cycles. These results are comparable to those achieved using traditional furnace-based carbonization processes, such as carbonizing HC anodes at 1200 °C, validating the effectiveness of IPL-assisted processes. Additionally, surface and structural analyses revealed the development of pseudo-graphitic domains, crucial for enhanced sodium-ion storage. This research highlights IPL-assisted photothermal carbonization as a viable, time-efficient, and energy-saving alternative to conventional methods, offering a sustainable pathway for the large-scale production of HC anodes for future sodium-ion battery technologies. © 2025 Wiley-VCH GmbH. ⓘ Ryoo, Gyeongbeom;

○ ○ Article ⓘ Boosting selenium cathode performance through kinetic optimization ⓘ This study investigated the use of selenium nanowires (SeNWs) and a poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) coating layer to improve the performance of lithium-selenium batteries. The use of SeNWs and PEDOT:PSS eliminates the need for high-temperature and high-pressure processes in the manufacture of selenium electrodes. By combining SeNWs with carbon nanotubes, we fabricated an electrode with a one-dimensional structure that showed high electron transfer and high conductivity. Providing a PEDOT:PSS coating increased the electrode's conductivity, with the coating layer suppressing the shuttle effect of lithium polyselenides (LiPSes). Impedance values and the diffusion coefficient (2.32 x 10(-12) cm(2) s(-1)) indicated significantly high ion diffusion in the electrode. The improved electrochemical performance of the coated electrode was verified through DFT calculations, which showed higher binding energies between the coated electrode surface and LiPSes, and lower activation energies for conversion reactions. Overall, charge and discharge results confirmed the improvement in the kinetic performance and stability, with the electrode maintaining a reversible capacity of 436.9 mAh g(-1) after 100 cycles. The use of SeNWs, carbon nanotubes, and PEDOT:PSS can effectively help address key challenges in battery technology, such as volume expansion and the shuttle effect. ⓘ Seo, Harim; Ryu, Seokgyu; Seo, Jihoon; Kim, Patrick Joohyun; Yoo, Jeeyoung ⓘ Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Clarkson Univ, Dept Chem & Biomol Engn, Potsdam, NY 13699 USA; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea ⓘ ; Yoo, Jeeyoung/AAH-1359-2019; Seo, Jihoon/ABI-6972-2020 ⓘ 58108938400; 57192435552; 55821491100; 57195611779; 56046607500 ⓘ jyoo@knu.ac.kr; ⓘ JOURNAL OF POWER SOURCES ⓘ J POWER SOURCES ⓘ 0378-7753 1873-2755 645 SCIE CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 7.9 14.8 0 2025-05-07 ⓘ 0 0 Lithium-selenium batteries; Conversion cathode; Shuttle effect; Conductive coating; PEDOT:PSS; CNTs ⓘ HIERARCHICAL POROUS CARBON; RECHARGEABLE LITHIUM; HIGH-CAPACITY; SE; CHALLENGES; SULFUR ⓘ CNTs; Conductive coating; Conversion cathode; Lithium-selenium batteries; PEDOT:PSS; Shuttle effect ⓘ Coated wire electrodes; Diffusion coatings; Lithium batteries; Selenium compounds; CNT; Coating layer; Conductive coatings; Conversion cathode; Ethylenedioxythiophenes; Lithium-selenia battery; Poly (3,4-ethylenedioxythiophene) polystyrene sulphonate; Poly(styrene sulfonate); Polyselenides; Shuttle effect; Activation energy ⓘ English 2025 2025-07-30 10.1016/j.jpowsour.2025.237122 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Characterization and Fungicide Sensitivity of Colletotrichum spp. from Capsicum Peppers in South Korea ⓘ Capsicum peppers, peppers from plants of the genus Capsicum (family Solanaceae), are widely cultivated in South Korea, where annual production was 92,756 tons in 2021, 54.4% higher than that of the previous year. Occurring throughout the production cycle, anthracnose is a major disease limiting commercial Capsicum pepper production worldwide, including in South Korea. This study investigates the diversity and pathogenicity of Colletotrichum species responsible for Capsicum pepper anthracnose in Gyeongbuk, South Korea, focusing on disease incidence and symptomatology in the field and the identification, morphological characteristics, pathogenicity, and fungicide sensitivity of the causative species. Disease incidence ranged from 30 to 50%, with samples categorized into three distinct symptom types, aiding accurate field diagnosis. Phylogenetic analysis classified 41 isolates into six species in the C. acutatum, gloeosporioides, and truncatum species complexes, revealing significant genetic diversity. Morphological characterization supported these identifications, providing a comprehensive profile. Pathogenicity tests confirmed that all identified species induced typical anthracnose lesions, with lesion size variations suggesting differential aggressiveness. Temperature significantly influenced mycelial growth, with optimal growth between 20 and 26 degrees C and C. truncatum demonstrating high temperature tolerance. In vitro fungicide sensitivity tests showed variable responses, with tebuconazole being generally effective.

○ ○ Article ⓘ Comprehensive understanding of the effects of imbalanced cell via battery module tests for further usage of cycled batteries ⓘ In this study, a comprehensive understanding on the battery module with an imbalanced cell is assessed in terms of its electrical, thermal, and electrochemical effects. By conducting electrical and thermal analysis using a 2 x 2 battery module for electric vehicle battery pack representative unit, normally combined with series and parallel, we observe property variations at the charge and discharge voltage profiles, as well as impacts of distinct reactions by series and parallel connections. The series-connected cell configuration on the module corresponds to the voltage variance, while the parallelconnected one induces temperature disparity. This comprehensive examination through two modules (model vs. reference module) is conducted to ascertain whether the outcomes of the electrical and thermal property analyses correspond to the internal chemical condition and configuration of the battery when the imbalanced modules connect in series and parallel are in operation. Our findings reveal a significant relationship between the electrical imbalances in each cell, the thermal consequences on the battery module, and the electrochemical impacts on the electrodes. However, we also reveal that there are normal cells among battery module when degraded with imbalances. Based on those results, our research provides economical information for the process of repurposing battery electrodes from imbalanced battery modules that will be appeared after cycled (or degraded) electric vehicle battery, which is crucial for improving the efficiency of an imbalanced batteries. ⓘ Oh, Jimin; Lee, Miyoung; Ko, Eunjin; Kim, Kwang Man; Kim, Jonghoon ⓘ Kyungpook Natl Univ, Adv Inst Sci & Technol, Dept Smart Mobil Engn, 80 Daehak Ro, Daegu 41566, South Korea; Elect & Telecommun Res Inst, ICT Creat Res Lab, Daejeon 34129, South Korea; Chungnam Natl Univ, Dept Elect Engn, Energy Storage Convers Lab, 99 Daehak Ro, Daejeon, South Korea ⓘ ⓘ 57203759688; 57271299400; 59093263200; 8672843900; 58163377300 ⓘ ojmhiin@knu.ac.kr; whdgns0422@cnu.ac.kr; ⓘ JOURNAL OF POWER SOURCES ⓘ J POWER SOURCES ⓘ 0378-7753 1873-2755 631 SCIE CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 7.9 14.8 0 2025-05-07 ⓘ 0 1 Chemically imbalanced cell; Electric and thermal analysis; Electrochemical analysis; Battery module; Electrode re-use ⓘ LITHIUM-ION BATTERY; ELECTRIC VEHICLE-BATTERIES; FUTURE; ENERGY; REUSE; LIFE; MODEL; PACK ⓘ Battery module; Chemically imbalanced cell; Electric and thermal analysis; Electrochemical analysis; Electrode re-use ⓘ Battery modules; Cell-be; Cell/B.E; Chemically imbalanced cell; Electric and thermal analyze; Electric vehicle batteries; Electrochemical analysis; Electrode re-use; Module tests; Thermal; Battery Pack ⓘ English 2025 2025-03-01 10.1016/j.jpowsour.2025.236282 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhanced energy harvesting performance of bendable thermoelectric generator enabled by trapezoidal-shaped legs ⓘ Thermoelectric generators (TEGs) have gained attention as a promising technology for clean energy harvesting. Improving the energy conversion efficiency of TEGs is crucial for realizing the thermoelectric (TE)-based selfpowered system. Herein, the shape and surface area of the TE legs and its impact on the energy conversion performance were evaluated systematically. The trapezoidal-shaped legs (TSL)-based TEGs were fabricated by truncating the top side of a cuboid structure with various top surface areas. We found that there is an inverse relationship between the truncated cross-sectional area and thermoelectric output values of the TSL-TEGs. This improvement in performance is attributed to the reduction in the overall thermal conductance of the TSL-TEG, which allows for a more significant Delta T value to be sustained between the hot and cold ends of the TE leg. Particularly, the TSL-TEG with top surface area of 2.5 x 2.5 mm2 converts the output power of 0.60 mW from a temperature gradient (Delta T) of = 200 K, which represents a two-fold increase compared to the cuboid-shaped legs (5 x 5 mm2)-based TEG. Additionally, to theoretically verify the effective conversion efficiency of TSL-TEGs, we conducted a finite element analysis with Multiphysics simulation and compared the calculated results acquired from leg's structures. Finally, we have demonstrated the energy harvesting of a bendable TEG made of TSLs, generating 0.38 mA and 30 mV at Delta T = 50 K when attached to the hot-curved metal object in a real-time lowgrade thermal energy environment. ⓘ Okirigiti, Momanyi Amos; Kim, Cheol Min; Choi, Hyejeong; Alluri, Nagamalleswara Rao; Baek, Changyeon; Lee, Min-Ku; Lee, Gyoung-Ja; Park, Kwi-Il ⓘ Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Innovat Semicond Educ & Res Ctr Future Mobil, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Automot Parts & Mat, Daegu 41566, South Korea; Korea Atom Energy Res Inst, Nucl Syst Integr Sensing & Diag Res Div, Daejeon 34057, South Korea ⓘ ; Alluri, Nagamalleswara Rao/K-1696-2015; Park, Kwiil/LKN-9445-2024 ⓘ 59491652600; 59441985400; 59490795700; 56527074500; 57095549400; 59302175900; 8588965200; 35280874200 ⓘ leegj@kaeri.re.kr; kipark@knu.ac.kr; ⓘ JOURNAL OF POWER SOURCES ⓘ J POWER SOURCES ⓘ 0378-7753 1873-2755 631 SCIE CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 7.9 14.8 0 2025-05-07 ⓘ 0 0 Thermoelectric generators; Bismuth telluride; Seebeck coefficient; Bendable; Trapezoidal legs ⓘ ⓘ Bendable; Bismuth telluride; Seebeck coefficient; Thermoelectric generators; Trapezoidal legs ⓘ Energy conversion efficiency; Energy harvesting; Tellurium compounds; Thermal gradients; Thermoelectric energy conversion; Thermoelectricity; Bendable; Bismuth telluride; Energy; Performance; Seebeck; Surface area; Thermoelectric; Thermoelectric generators; Top surface; Trapezoidal leg; Bismuth compounds ⓘ English 2025 2025-03-01 10.1016/j.jpowsour.2025.236254 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhancing precision in two-dimensional lithium battery modeling using an improved discharge boundary condition setting within the lattice Boltzmann method framework for broad applications ⓘ To enhance the modeling accuracy of the two-dimensional lithium battery model and improve its precision in predicting the discharge process, this study proposes an approach based on a new discharge boundary condition setting. In this method, when a battery is connected to a load circuit, electrochemical reactions occurring at the interface between the electrode particles and the electrolyte induce uniform changes in the surface potentials of all electrode particles in the cathode and anode regions, rather than being confined to the battery terminals near the current collectors. These changes are quantified based on the load current using an optimization algorithm, instead of conductivity calculations. Leveraging this approach, a two-dimensional battery model is developed within an improved lattice Boltzmann method framework. Simulation results reveal that the model satisfies current and charge conservation principles, substantially improves computational accuracy, and demonstrates high stability. Furthermore, the two-dimensional local variations in lithium/lithium-ion concentrations predicted by the model align well with the general mechanism analysis. Notably, this model demonstrates versatility for broad applications, effectively predicting battery behavior under varied discharge conditions, such as constant current and constant-resistance discharge modes, and can handle electrode particle size heterogeneity. ⓘ Yang, Ming-Dai; Hu, Sheng-Qiao; Li, Chang-Ping; Kwak, Yein; Ko, Tae Jo ⓘ Yeungnam Univ, Sch Mech Engn, 280 Daehak Ro, Gyoungsan Si 38541, Gyeongsangbug D, South Korea; Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea; Fuyao Univ Sci & Technol, Sch Intelligent Mfg & Future Technol, Fuzhou 350100, Fujian, Peoples R China ⓘ Hu, Shengqiao/GYJ-4392-2022; KO, TAEJO/NQF-8909-2025 ⓘ 57357611100; 57216397455; 36518956600; 57194639803; 57225990816 ⓘ tjko@yu.ac.kr; ⓘ JOURNAL OF POWER SOURCES ⓘ J POWER SOURCES ⓘ 0378-7753 1873-2755 644 SCIE CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 7.9 14.8 0 2025-05-07 ⓘ 0 0 Two-dimensional lithium battery model; Discharge boundary condition setting; Electrode particles; Lattice Boltzmann method (LBM); Reaction current density optimization ⓘ LI-ION BATTERY; ELECTRON-TRANSPORT; SIMULATION; CATHODES; CHARGE ⓘ Discharge boundary condition setting; Electrode particles; Lattice Boltzmann method (LBM); Reaction current density optimization; Two-dimensional lithium battery model ⓘ Lithium batteries; Condition; Discharge boundary condition setting; Electrode particle; Lattice Boltzmann method; Lithium battery modeling; Optimisations; Reaction current; Reaction current density optimization; Two-dimensional; Two-dimensional lithium battery model; Electrolytes ⓘ English 2025 2025-07-15 10.1016/j.jpowsour.2025.237100 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Enhancing reversibility of zinc metal for Zn||I2 aqueous battery via nanophase-clustered perfluorosulfonic acid layers with tuned sulfonic acid densities ⓘ Zinc metal batteries (ZMBs) are considered promising candidates for large-scale energy storage systems due to zinc's natural abundance, low cost, and intrinsic safety. However, the commercialization of ZMBs is hampered by uncontrolled Zn dendrite growth and interfacial instability, which result in poor cycling performance and safety concerns. Although perfluorosulfonic acid (PFSA) polymers have been previously used as protective layers, the fundamental relationship between their sulfonic acid group density and Zn plating behavior has remained unclear. In this study, we unveil a previously unexplored mechanism by which the sulfonic acid group density governed by the equivalent weight (EW) of PFSA dictates the formation of nanophase-separated ionic clusters that directly influence Zn2+ ion transport, transference number, and plating morphology. We reveal that optimized PFSA structures not only suppress dendrite formation but also promote preferential Zn deposition along the (002) lattice plane, rather than the conventional (100) orientation. This lattice-oriented growth leads to significantly improved Zn anode reversibility and stability. As a result, the PFSA-Zn||I2 full cell demonstrates long-term cycling over 1489 cycles at 4.3 mAh cm-2, maintaining 88.8 % capacity retention and a high Coulombic efficiency of 99.8 %. ⓘ Jung, Hyunjin; Choi, Young-Gyu; Lee, Jaeyeon; Kim, Boyeon; Ryu, Myunghyun; Chun, Sang-Eun; Chang, Bong-Jun; Heo, Jiyun; Jung, Kyu-Nam; Oh, Myung Seok; Lee, Jinhong ⓘ Korea Inst Energy Res KIER, Renewable Energy Inst, 152 Gajeong Ro, Daejeon 34129, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Korea Reserach Inst Chem Technol, Interface Mat & Chem Engn Res Ctr, Daejeon 34114, South Korea; Chungnam Natl Univ, Dept Polymer Sci & Engn, 99 Daehak Ro, Daejeon 34134, South Korea; Gachon Univ, Sch Chem Biol & Battery Engn, Seongnam 13120, South Korea ⓘ ⓘ 59300087300; 59951057900; 59239491600; 59299507200; 55669109100; 36801080300; 7402600527; 57195580060; 7402479940; 59756589000; 57214786163 ⓘ mitamire@kier.re.kr; peter_oh@krict.re.kr; jinhong02@kier.re.kr; ⓘ JOURNAL OF POWER SOURCES ⓘ J POWER SOURCES ⓘ 0378-7753 1873-2755 652 SCIE CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 7.9 14.8 N/A ⓘ 0 0 Zinc metal battery; Perfluorosulfonic acid; Dendrite suppression; Sulfonic acid density ⓘ ION; NAFION; STATE ⓘ Dendrite suppression; Perfluorosulfonic acid; Sulfonic acid density; Zinc metal battery ⓘ Density (specific gravity); Morphology; Secondary batteries; Zinc; Zinc compounds; Zinc plating; Aqueous batteries; Dendrite suppression; Large-scales; Nanophases; Perfluorosulfonic acid; Sulfonic acid groups; Sulphonic acid density; Sulphonic acids; Zinc metal; Zinc metal battery; Zinc deposits ⓘ English 2025 2025-10-01 10.1016/j.jpowsour.2025.237673 ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ Manifold embedding of geological and geophysical observations for non-stationary subsurface property estimation using geodesic Gaussian processes ⓘ Traditional methods for geological characterization often overlook or oversimplify the challenge of subsurface non-stationarity. This study introduces an innovative methodology that uses ancillary data, such as geological insights and geophysical exploration, to accurately delineate the spatial distribution of subsurface petrophysical properties in large, non-stationary geological fields. The approach leverages geodesic distance on an embedded manifold, with the level-set curve linking observed geological structures to intrinsic non-stationarity. Critical parameters rho and beta were identified, influencing the strength and dependence of estimates on secondary data. Comparative evaluations demonstrated that this method outperforms traditional kriging, particularly in representing complex subsurface structures. This enhanced accuracy is crucial for applications such as contaminant remediation and underground repository design. While focused on two-dimensional models, future work should explore three-dimensional applications across diverse geological structures. This research provides novel strategies for estimating non-stationary geologic media, advancing subsurface characterization. ⓘ Park, Eungyu; Piao, Jize; Jun, Hyunggu; Kim, Yong-Sung; Suk, Heejun; Han, Weon Shik ⓘ Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Daejeon 34132, South Korea; INSUNG D&M Inc, Seoul 08312, South Korea; Yonsei Univ, Dept Geosyst Sci, Seoul 03722, South Korea ⓘ Han, Weon Shik/KCY-0126-2024 ⓘ 23995577700; 57183819700; 59769212000; 59762646700; 23996203400; 57226420125 ⓘ egpark@knu.ac.kr; ⓘ COMPUTERS & GEOSCIENCES ⓘ COMPUT GEOSCI-UK ⓘ 0098-3004 1873-7803 202 SCIE COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;GEOSCIENCES, MULTIDISCIPLINARY ⓘ 2024 4.4 14.9 N/A ⓘ 1 1 Manifold embedding; Geodesic distance; Level-set curve; Subsurface property; Non-stationarity; Spatial statistics ⓘ HETEROGENEOUS AQUIFER; TOMOGRAPHY; DISPERSION ⓘ Geodesic distance; Level-set curve; Manifold embedding; Non-stationarity; Spatial statistics; Subsurface property ⓘ Core analysis; Electromagnetic prospecting; Gravitational prospecting; Seismic prospecting; Subsalt strata; Telluric prospecting; Embeddings; Geodesic distances; Geological structures; Level Set; Level-set curve; Manifold embedding; Non-stationarities; Nonstationary; Spatial statistics; Subsurface properties; Gaussian method; geodesy; geophysical method; kriging; remediation; repository; spatial distribution; two-dimensional modeling; underground storage; Radioactive prospecting ⓘ English 2025 2025-08 10.1016/j.cageo.2025.105958 ⓘ 바로가기 바로가기 바로가기 바로가기
