| ○ | ○ | Article | Enhancement of piezoelectric properties in KNN-based lead-free ceramics through controlled NaNbO3 seed addition and phase structure engineering | This study investigates the effects of introducing 0-5 mol% NaNbO3 (NN) seeds on the structural, microstructural, dielectric, ferroelectric, and piezoelectric properties of KNN-based lead-free piezoelectric ceramics. All samples with the final composition 0.96[0.95(K0.52Na0.48NbO3) - 0.05LiSbO3] - 0.04SrZrO3-CuO (KNNLS-SZ-C) were sintered at 1060 degrees C for 6 h. X-ray diffraction analysis revealed a perovskite single phase for 0-5 mol% NN seed contents, with a multiphase coexistence of tetragonal, orthorhombic, and rhombohedral structures. As seed content increased from 0 to 3 mol%, the rhombohedral fraction increased while tetragonal and orthorhombic fractions decreased. SEM micrographs showed abnormal grain growth at 1-2 mol% seeds, transitioning to normal grain growth beyond 3 mol%. Optimal piezoelectric and electromechanical properties including d33 = 323 pC/N, kp = 0.39 were obtained at 3 mol% NN seed, attributed to the favorable multiphase structure fraction and moderate grain size. This work elucidates the interplay between NN seed addition, phase fraction distribution, and microstructural development in tuning the piezoelectric performance of these lead-free ceramics. | Kim, Sumi; Oh, Seong-Uk; Kim, Dokyum; Lee, Jung-A.; Heo, Young-Woo; Lee, Joon-Hyung; Nahm, Sahn | Kyungpook Natl Univ, Dept Mat Sci & Engn, Daegu 41566, South Korea; Korea Univ, Dept Mat Sci & Engn, Seoul 02841, South Korea | 58813647900; 57856319400; 57212308311; 55108410500; 7004298542; 57204923460; 57030636500 | joonlee@knu.ac.kr; snahm@korea.ac.kr; | JOURNAL OF MATERIALS SCIENCE | J MATER SCI | 0022-2461 | 1573-4803 | 60 | 7 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.9 | 41.8 | 0 | 2025-05-07 | 0 | 0 | SODIUM-POTASSIUM NIOBATE; GOOD THERMAL-STABILITY; ABNORMAL GRAIN-GROWTH; FERROELECTRIC PROPERTIES; ELECTRICAL-PROPERTIES; MICROSTRUCTURE; TRANSITION; SIZE; BEHAVIOR; SRZRO3 | Ferroelectric ceramics; Ferroelectricity; Grain growth; Microstructural evolution; Phase structure; Piezoelectric ceramics; Piezoelectricity; Pressure vessels; Sintering; X ray diffraction analysis; Dielectrics property; Diffraction analysis; Ferroelectric and piezoelectric properties; Lead free ceramics; Lead-free piezoelectric ceramic; Micro-structural properties; Piezoelectric property; Seed addition; Structure engineering; X- ray diffractions; Perovskite | English | 2025 | 2025-02 | 10.1007/s10853-025-10676-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Nanoadsorbents; advanced tailored strategies for precious metals recovery from waste sources | Recovering precious metals (PMs) from diverse waste sources, including electronic waste (E-waste), mining residues, and industrial effluents, has become a critical focus due to their immense economic value and limited natural reserves. Nanoadsorbents, renowned for their high surface area, tunable surface properties, and exceptional physicochemical characteristics, have emerged as highly promising candidates for the efficient recovery of metals such as gold (Au), silver (Ag), platinum (Pt), and palladium (Pd). However, the full realization of their potential remains in its infancy, necessitating further research and significant advancements to optimize their efficiency. This review highlights two cutting-edge materials-porous carbons and metal-organic frameworks that stand out for their extraordinary surface areas, customizable properties, and selective adsorption capabilities, making them particularly suitable for PM recovery. Additionally, the review provides a critical evaluation of the advantages and limitations of these materials, offering a roadmap for selecting and enhancing adsorbents for PM recovery. We believe that this comprehensive analysis will drive innovation in material development, facilitating more efficient recovery of precious metals from waste streams. | Neelam | Kyungpook Natl Univ, Inst Basic Sci, Dept Chem, Daegu, South Korea | 59558686100 | neelam06@gmail.com; | JOURNAL OF MATERIALS SCIENCE | J MATER SCI | 0022-2461 | 1573-4803 | 60 | 7 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.9 | 41.8 | 0 | 2025-05-07 | 0 | 0 | MUNICIPAL SOLID-WASTE; SELECTIVE ADSORPTION; ORGANIC FRAMEWORKS; ELECTRONIC WASTE; CARBON; GOLD; PALLADIUM; CATALYSTS; MOF; HEAVY | Gold deposits; Metal cutting; Nanoclay; Palladium; Silver; Silver deposits; Economic values; Electronics wastes; High surface area; Industrial effluent; Mining residues; Nanoadsorbents; Natural reserves; Precious metal recoveries; Property; Tunables; Metal recovery | English | 2025 | 2025-02 | 10.1007/s10853-025-10660-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Long-term functional outcomes in patients with isolated cerebellar infarction: the KOSCO study | Background There are relatively few reports on the long-term sequential functional recovery and prognosis in patients with cerebellar infarction. The aim of this study was to investigate the long-term recovery of multifaceted functional outcomes up to 36 months after onset and the functional prognosis of isolated cerebellar infarction. Methods This study was a retrospective analysis of the Korean Stroke Cohort for Functioning and Rehabilitation (KOSCO) data up to 36 months after onset. Isolated cerebellar infarction was defined as the presence of lesions in the cerebellum without lesions in other brain parenchyma. We assessed multifaceted functional domains, including motor (Fugl-Meyer Assessment, FMA), ambulatory (Functional Ambulation Category, FAC), cognitive (Korean Mini-Mental State Examination, K-MMSE), swallowing (American Speech-Language-Hearing Association National Outcome Measurement System Swallowing Scale, ASHA-NOMS), and language functions (Short version of the Korean Frenchay Aphasia Screening Test, Short K-FAST), using serial measurements. In addition, functional outcome was assessed with the Functional Independence Measure (FIM) up to 36 months after onset. Results Among 390 screened isolated cerebellar infarction patients, a total of 183 patients were included in this study. Cognitive (mean[SD] of K-MMSE 27.6 +/- 3.6) and swallowing (ASHA-NOMS 6.8 +/- 0.7) functions showed significant improvement up to 3 months (p < 0.05). Motor (FMA 98.8 +/- 3.8) and language (ASHA-NOMS 6.9 +/- 0.4) functions improved significantly up to 6 months (p < 0.05). Furthermore, ambulatory function (FAC 4.7 +/- 0.9) and functional independency (FIM 122.2 +/- 12.0) continued to improve up to 12 months (p < 0.05). Vascular territory involving superior cerebellar artery, older age, female sex, and greater initial severity were identified as negative independent prognostic factors predicting functional outcome measured by FIM at 12 months after stroke. Conclusion The plateau of recovery in multifaceted functional outcomes varied among patients with cerebellar infarction. Functional independence plateaued at 12 months and showed a relatively favorable prognosis up to 36 months after stroke. | Lee, Ho Seok; Sohn, Min Kyun; Lee, Jongmin; Kim, Deog Young; Shin, Yong-Il; Oh, Gyung-Jae; Lee, Yang-Soo; Joo, Min Cheol; Lee, So Young; Song, Min-Keun; Han, Junhee; Ahn, Jeonghoon; Lee, Young-Hoon; Kim, Dae Hyun; Kim, Young-Taek; Kim, Yun-Hee; Chang, Won Hyuk | Sungkyunkwan Univ, Sch Med, Samsung Med Ctr,Dept Phys & Rehabil Med, Ctr Prevent & Rehabil,Heart Vasc Stroke Inst, Seoul, South Korea; Chungnam Natl Univ, Coll Med, Dept Rehabil Med, Daejeon, South Korea; Konkuk Univ, Sch Med, Sch Med, Seoul, South Korea; Yonsei Univ, Dept & Res Inst Rehabil Med, Coll Med, Seoul, South Korea; Pusan Natl Univ, Yangsan Hosp, Dept Rehabil Med, Sch Med, Yangsan, South Korea; Wonkwang Univ, Sch Med, Dept Prevent Med, Iksan 570749, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Rehabil Med, Daegu, South Korea; Wonkwang Univ, Sch Med, Sch Med, Iksan 570749, South Korea; Jeju Natl Univ, Jeju Natl Univ Hosp, Dept Anethesiol, Sch Med, Jeju City, South Korea; Chonnam Natl Univ, Med Sch, Med Sch, Gwangju, South Korea; Hallym Univ, Dept Stat, Chunchon 200702, Kangwon Do, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul, South Korea; Chungnam Natl Univ Hosp, Dept Prevent Med, Daejeon, South Korea; Sungkyunkwan Univ, Sch Med, Sch Med, Suwon, South Korea; Sungkyunkwan Univ, Dept Hlth Sci & Technol, Dept Med Device Management Res, SAIHST, Seoul, South Korea | Kim, Young/AEP-2940-2022; Kim, Yun-Hee/GVS-6426-2022; kim, deog young/Q-8498-2019 | 57222648792; 7101840459; 57202882113; 55375583000; 55890990500; 7007056685; 57202952463; 56982599700; 57202327370; 55375416600; 57192890252; 8855402200; 55716155400; 57206099341; 57211411051; 57020121600; 35301717900 | yunkim@skku.edu; wh.chang@samsung.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 16 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2024 | 2.8 | 41.9 | 0 | 2025-05-07 | 0 | 0 | ischemic stroke; cerebellum; long-term outcome; functional prognosis; recovery | ISCHEMIC-STROKE; RECOVERY; REHABILITATION; RELIABILITY; MANAGEMENT; DIAGNOSIS; PERFORMANCE; IMPAIRMENT; VALIDATION; PROGNOSIS | cerebellum; functional prognosis; ischemic stroke; long-term outcome; recovery | adult; aged; American Speech-Language-Hearing Association National Outcome Measurement System Swallowing Scale; Article; atherosclerosis; cerebellum infarction; cerebrovascular accident; Charlson Comorbidity Index; cognition; cohort analysis; computer assisted tomography; female; Fugl-Meyer assessment; Functional Ambulation Category; Functional Independence Measure; human; hypertension; major clinical study; male; mental disease assessment; middle aged; Mini Mental State Examination; multicenter study; National Institutes of Health Stroke Scale; nuclear magnetic resonance imaging; prognosis; retrospective study; Short version of the Korean Frenchay Aphasia Screening Test; superior cerebellar artery | English | 2025 | 2025-03-10 | 10.3389/fneur.2025.1541245 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Application of polyurethane precursors comprising pyrazole-blocking waterborne polyurethane dispersion and recycled polyol to optical poly(ethylene terephthalate) films | In this study, we investigated the application of polyurethane (PU) coating on poly(ethylene terephthalate) (PET) films for optical film applications using pyrazole-blocked waterborne PU dispersion (PUD) (PUDpy) and PET-recycled polyol. Real-time Fourier transform infrared spectroscopy, dynamic mechanical analysis, ultra-micro hardness tests, ellipsometry and ultraviolet–visible spectroscopy were used to analyse the deblocking process for PUDpy, the reaction between PUDpy and polyol and the optical properties of the PU-coated PET film. The PU-coated PET films prepared in this study were clear, smooth and transparent enough for optical film applications. The deblocking of pyrazole and activation of isocyanate (NCO) groups started at 100 °C and ended at 180 °C, and the PU reaction between the activated NCO and polyol started immediately after NCO activation and lasted up to a maximum operation temperature of 240 °C. Notably, the PU reaction continued even after cooling to room temperature (25 °C), thereby necessitating a post-curing process to achieve complete curing. As the polyol content in the coating layer increased, the refractive index increased, whereas the coating layer hardness decreased. The evaluation of the compositional effects of the PUDpy:polyol precursor solution indicated that the optimal optical and mechanical properties of the PU-coated PET film were achieved when equal amounts of PUDpy and polyol were used in the precursor solution. © The Author(s), under exclusive licence to The Polymer Society of Korea 2025. | Jang, Yoon-Jung; Kim, Jeong-Sam; Park, Soo-Young | School of Applied Chemical Engineering, Polymeric Nano Materials Laboratory, Kyungpook National University, Daegu, 41566, South Korea, Toray Advanced Materials Korea Inc., 249-29, 4 Gongdan-Ro, Gyeongsangbuk-do, Gumi, 39422, South Korea; Toray Advanced Materials Korea Inc., 249-29, 4 Gongdan-Ro, Gyeongsangbuk-do, Gumi, 39422, South Korea; School of Applied Chemical Engineering, Polymeric Nano Materials Laboratory, Kyungpook National University, Daegu, 41566, South Korea | 59918609900; 59918840100; 57194041850 | psy@knu.ac.kr; | Macromolecular Research | MACROMOL RES | 1598-5032 | 2092-7673 | SCIE | POLYMER SCIENCE | 2024 | 3.4 | 42.0 | 0 | 2025-06-11 | 0 | Blocking; In-line coating; Optical film; Poly(ethylene terephthalate); Polyurethane; Pyrazole | Brinell Hardness; Density (optical); Hardness testing; Microhardness; Optical coatings; Photographic films; Refractive index; Blockings; Coating layer; Deblocking; Inline coatings; Optical-; Poly(ethylene terephthalate); Poly(ethylene) terephthalate; Polyurethane dispersions; Pyrazoles; Waterborne Polyurethane; Fourier transform infrared spectroscopy | English | Article in press | 2025 | 10.1007/s13233-025-00414-6 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Review | Research roadmap for sustainable polymeric materials in Korea | Polymer technology has significantly transformed modern society and is a foundation for the global economy. However, the pervasive issue of plastic waste pollution has cast a negative light on the industry. As the world aims for a carbon-neutral future by 2050, a paradigm shift from fossil-based to sustainable polymeric materials is imperative. While biopolymers derived from renewable sources offer promising potential to mitigate plastic pollution and reduce carbon emissions, their current performance and cost disadvantages compared to conventional petrochemical-based polymers hinder their widespread adoption. As a global leader, the Korean plastics industry faces increasing competitive pressures and growing environmental concerns. To address these challenges, the Eco-materials Division of the Polymer Society of Korea (PSK) was established in 2023 to promote collaboration among academia, industry, and research institutions. This review consolidates the PSK's multidisciplinary research efforts, outlines key challenges, and proposes a roadmap for future research directions in sustainable polymer technologies. Key focus areas include mechanochemical plastic upcycling, biomass-derived smart materials, renewable gas barrier films for food packaging, microbial plastic degradation, biomass content analysis, bio-based membranes, self-healing materials, melt compounding, and biodegradable polymer synthesis. By sharing expertise and fostering collaborative partnerships, this roadmap aims to accelerate innovation in the sustainable polymer industry and create a unified vision among stakeholders.Graphical abstractResearch roadmap of the Polymer Society of Korea (PSK) for sustainable polymeric materials. | Kim, Jeong F.; Kim, Hee Joong; Park, Jeyoung; Jeon, Hyeonyeol; Kim, Jeung Gon; Choi, Chungryong; Nam, Ki-Ho; Shin, Giyoung; Park, Sae Hume; Shin, Jihoon; Kang, Dong-Ku; Oh, Dongyeop X.; Lee, Dong Yun; Hong, Sung Woo; Yi, Gi-Ra | Kyung Hee Univ, Dept Chem Engn, Yongin 17104, South Korea; Inha Univ, Dept Polymer Sci & Engn, Incheon 22212, South Korea; Inha Univ, Program Environm & Polymer Engn, Incheon 22212, South Korea; Sogang Univ, Dept Chem & Biomol Engn, Seoul 04107, South Korea; Korea Res Inst Chem Technol KRICT, Res Ctr Biobased Chem, Ulsan 44429, South Korea; Jeonbuk Natl Univ, Dept Chem, Jeonju 54896, South Korea; Jeonbuk Natl Univ, Res Inst Phys & Chem, Jeonju 54896, South Korea; Kumoh Natl Inst Technol, Dept Polymer Sci & Engn, Gumi 39177, South Korea; Kyungpook Natl Univ, Dept Text Syst Engn, Daegu 41566, South Korea; Ctr CO2 & Energy, Korea Res Inst Chem Technol KRICT, Daejeon 34114, South Korea; Incheon Natl Univ, Dept Chem, Incheon 22012, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea | Kim, Jeung Gon/HCG-9332-2022; Oh, Dongyeop/V-3668-2018; Kim, Jeong/LIH-3658-2024 | 55702313800; 57049877000; 35734782200; 37098880000; 56379608400; 56688020600; 55553181500; 57221629724; 57191673709; 8506041900; 7402889623; 58700704100; 57211001605; 57215559409; 7101660741 | d.oh@inha.ac.kr; dongyunlee@knu.ac.kr; swhong@kitech.re.kr; yigira@postech.ac.kr; | MACROMOLECULAR RESEARCH | MACROMOL RES | 1598-5032 | 2092-7673 | 33 | 5 | SCIE | POLYMER SCIENCE | 2024 | 3.4 | 42.0 | 0 | 2025-05-07 | 0 | 0 | Polymer Society of Korea; Eco-friendly materials; Sustainability; Closed-loop lifecycle; Bioplastic; Biodegradation | DEGRADATION; WASTE; TRANSPARENT; ENERGY; LIFE | Biodegradation; Bioplastic; Closed-loop lifecycle; Eco-friendly materials; Polymer Society of Korea; Sustainability | Carbon films; Compounding (chemical); Elastomers; Ionomers; Kyoto Protocol; Packaging materials; Plastic films; Plastics industry; Reinforced plastics; Bio-plastics; Closed-loop; Closed-loop lifecycle; Eco-friendly materials; Global economies; Polymer society of korea; Polymer technology; Research roadmap; Roadmap; Sustainable polymers; Gas permeable membranes | English | 2025 | 2025-05 | 10.1007/s13233-024-00357-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | Side chain effect of benzodithiophene on the diketopyrrolopyrrole-based copolymer for the opto-electronic properties | This study investigates synthesis, thermal, optical, and morphological properties of two DPP-based copolymers, PBDTTT-DPP-C12 (poly{2,6-bis- 5-(2-butyloctyl)thienothiophene-2-yl)benzo[1,2-b:4,5-b′]dithiophene-6-bis(5-thiophen-2-yl)-2,5-bis(2-decyltetradecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione}) and PBDTTT-DPP-C17 (poly{2,6-bis-5-(2–7-butyltridecyl)thienothiophene-2-yl)benzo[1,2-b:4,5-b′]dithiophene-6-bis(5-thiophen-2-yl)-2,5-bis(2-decyltetradecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione}), with different alkyl side chains. Both polymers were synthesized using a series of reactions (alkylation, lithiation, and bromination) and Stile coupling polymerization. The obtained polymer structures were confirmed using 1H NMR (Nuclear Magnetic Resonance). The thermal stability of both polymers, assessed via thermo-gravimetric analysis (TGA) and differential scanning calorimetry (DSC) showed high decomposition temperatures (Td) of 377 °C and 367 °C for PBDTTT-DPP-C12 and PBDTTT-DPP-C17, respectively, which indicate sufficient thermal stability. The polymers exhibited dual-band absorption, with maximum absorption at 669 nm for PBDTTT-DPP-C12 and 700 nm for PBDTTT-DPP-C17, showing a slight red shift when transitioning from solution to film. The electrochemical analysis via cyclic voltammetry (CV) revealed similar highest occupied molecular orbital (HOMO) levels of − 5.22 eV and − 5.23 eV for both polymers, while the lowest unoccupied molecular orbital (LUMO) levels were calculated to be 1.47 eV and 1.49 eV, respectively. Grazing incidence wide-angle X-ray scattering (GIWAXS) and atomic force microscopy (AFM) studies revealed differences in morphology and crystallinity of the films, with PBDTTT-DPP-C12 showing a more pronounced edge-on orientation. In photovoltaic devices, PBDTTT-DPP-C17 demonstrated a higher power conversion efficiency (PCE) of 2.8%, outperforming PBDTTT-DPP-C12 with a PCE of 1.8%. This work highlights the significant role of alkyl side chain length in modulating polymer morphology, crystallinity, and miscibility with electron acceptors, thus enhancing the photovoltaic performance of DPP-based polymers for organic solar cells. © The Author(s), under exclusive licence to The Polymer Society of Korea 2025. | Larasati, Karina Ayu; Park, Changwoo; Ayuningtias, Landep; Cha, Hyojung; Kim, Yun-Hi | Department of Chemistry & RIMA, Gyeongsang National University, Jinju-si, 52828, South Korea; School of Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; Department of Chemistry & RIMA, Gyeongsang National University, Jinju-si, 52828, South Korea; School of Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; Department of Chemistry & RIMA, Gyeongsang National University, Jinju-si, 52828, South Korea | 59698856300; 58549401800; 58914377800; 35885242200; 56066944400 | ykim@gnu.ac.kr; hcha@knu.ac.kr; | Macromolecular Research | MACROMOL RES | 1598-5032 | 2092-7673 | SCIE | POLYMER SCIENCE | 2024 | 3.4 | 42.0 | 0 | 2025-05-07 | 0 | Alkyl side chain; Copolymer; Diketopyrrolopyrrole; Organic solar cell; Photovoltaic performance | Aspect ratio; Chemical shift; Cracking (chemical); Elastomers; Ionomers; Silicones; Alkyl side chains; Benzodithiophene; Diketopyrrolopyrroles; Molecular-orbital level; Organics; Photovoltaic performance; Power conversion efficiencies; Side chain effects; Thermal; Thienothiophenes; Thiophene | English | Article in press | 2025 | 10.1007/s13233-025-00394-7 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Immortalization of epidural fat-derived mesenchymal stem cells: In vitro characterization and adipocyte differentiation potential | BACKGROUND Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapy due to their self-renewal capability, multilineage differentiation potential, and immunomodulatory effects. The molecular characteristics of MSCs are influenced by their location. Recently, epidural fat (EF) and EF-derived MSCs (EF-MSCs) have garnered attention due to their potential benefits to the spinal microenvironment and their high expression of neural SC markers. However, their clinical applications are limited due to cell senescence and limited accessibility of EF. Although many studies have attempted to establish an immortalized, stable SC line, the characteristics of immortalized EF-MSCs remain to be clarified. AIM To establish and analyze stable immortalized EF-MSCs. METHODS The phenotypes of EF-MSCs were analyzed using optical microscopy. Cell immortalization was performed using lentiviral vectors. The biomolecular characteristics of the cells were analyzed by immunoblotting, quantitative PCR, and proteomics. RESULTS The immortalized EF-MSCs demonstrated a significantly extended lifespan compared to the control group, with well-preserved adipogenic potential and SC surface marker expression. Introduction of human telomerase reverse transcriptase genes markedly increased the lifespan of EF-MSCs. Proteomics analysis revealed substantial increase in the expression of DNA replication pathway components in immortalized EF-MSCs. CONCLUSION Immortalized EF-MSCs exhibited significantly enhanced proliferative capacity, retained adipogenic potential, and upregulated the expression of DNA replication pathway components. | Lee, Seoung-Woo; Lim, Young-Ju; Kim, Hee-Yeon; Kim, Wansoo; Park, Wook-Tae; Ma, Min-Jung; Lee, Junho; Seo, Min-Soo; Kim, Young In; Park, Sangbum; Choi, Seong-Kyoon; Lee, Gun Woo | Daegu Gyeongbuk Inst Sci & Technol, Core Prot Resources Ctr, Daegu 42988, South Korea; Yeungnam Univ, Coll Med, Med Ctr, Dept Orthoped Surg, Daegu 42415, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Pathol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Vet Med, Lab Vet Tissue Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Vet Tissue Engn, Daegu 41566, South Korea; Cellexobio Ltd, Daegu 42415, South Korea; Michigan State Univ, Inst Quantitat Hlth Sci & Engn, E Lansing, MI 48824 USA; Yeungnam Univ, Coll Med, Dept Orthoped Surg, 170 Hyunchung Ro, Daegu 42415, South Korea | 57218827581; 57220206982; 58368914700; 57352897900; 57216658028; 59543242700; 57219032336; 35254332100; 57203948912; 55390841500; 55505432500; 55599978600 | gwlee1871@gmail.com; | WORLD JOURNAL OF STEM CELLS | WORLD J STEM CELLS | 1948-0210 | 17 | 1 | SCIE | CELL & TISSUE ENGINEERING;CELL BIOLOGY | 2024 | 3.6 | 42.2 | 0 | 2025-05-07 | 0 | 0 | Immortalization; Transfection; Stem cell; Epidural fat; Proteomics | STABILITY; MARROW; LINE | Epidural fat; Immortalization; Proteomics; Stem cell; Transfection | beta galactosidase; complementary DNA; lentivirus vector; telomerase reverse transcriptase; adipocyte; adipogenesis; adipose tissue; Article; cell aging; cell differentiation; cell immortalization; cell isolation; cell survival; controlled study; DNA replication; epidural fat derived mesenchymal stem cell; fluorescence activated cell sorting; human; human cell; human tissue; immunoblotting; in vitro study; light microscopy; mesenchymal stem cell; phenotype; proteomics; real time reverse transcription polymerase chain reaction; upregulation | English | 2025 | 2025-01-26 | 10.4252/wjsc.v17.i1.98777 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Letter | Potential of mesenchymal stem cell-derived exosomes in the treatment of androgenetic alopecia | Exosomes are derived from various cell types, including mesenchymal stem cells (MSCs), and play a crucial role in cellular communication, significantly influencing tissue repair and regeneration and facilitating the healing process.

A detailed analysis of the glasses' optical, structural, and luminescence properties were instigated to understand light emitting and scintillating behaviour. The oxidation state of Gd atom inside the glass found to be + 3. Stimulated emission cross section, radiative transition probability and branching of the metastable state of rare-earth ions were evaluated using Judd-Ofelt model and compared with other reported literature. Photo-Emission spectra were monitored at the UV-C band and X-rays. Luminescence was analysed with various excitation wavelengths and sources. Photoluminescence quantum yield show more than 22 % efficiency and show more than 15 % compared with other reported glasses. Luminescence intensity ratio was analysed and found that the Sm3+-ions do not occupy the inversion-symmetry which enhances the luminescence intensity in the present glass system. The CIE and CCT values were evaluated and discussed. | Rajaramakrishna, R.; Nikolay, Nikonorov; Wantana, N.; Kim, H. J.; Kothan, S.; Intachai, N.; Busayaporn, W.; Kaewkhao, J.; Parfenova, E.

| ○ | ○ | Article | Allosteric inhibition of cytosolic NADP plus -dependent isocitrate dehydrogenase by oxaloacetate | NADP+-dependent cytosolic isocitrate dehydrogenase (IDH1) plays a crucial role in providing reducing energy in response to oxidative stress through the oxidative decarboxylation of isocitrate. NADPH generated by IDH1 serves as an essential cofactor for fatty acid synthesis. The regulation of IDH1 activity is vital for the biological functions of NADPH within cells, and mutations in IDH1 have been implicated in various cancers. In an effort to identify small regulatory molecules for IDH1, we determined the crystal structures of mouse IDH1 complexed with isocitrate and with oxaloacetate. Each IDH1 comprises large and small domains that form an active site, along with a clasp domain that connects two IDH1 molecules for dimerization. Isocitrate was located at the active site in the presence of a magnesium ion, while oxaloacetate was found at a novel site formed by the two clasp domains, in addition to the active site. The activity of IDH1 was diminished in the presence of oxaloacetate and could not be restored by the addition of isocitrate, indicating the presence of allosteric regulation. The activity of the IDH1 H170A mutant, which is unable to bind oxaloacetate in the clasp domain, was unaffected by oxaloacetate. This allosteric regulatory site may serve as a potential target for novel IDH1 inhibitors. | Kim, Dong Kyu; Cho, Ha Yeon; Cho, Hyo Je; Kang, Beom Sik | Kyungpook Natl Univ, Sch Life Sci & Biotechnol, KNU Creat BioRes Grp, Daegu 41566, South Korea; Chungbuk Natl Univ, Dept Biochem, Cheongju 28644, South Korea | 57210928800; 24066656500; 57191187748; 35082104200 | hyojec@cbnu.ac.kr; bskang2@knu.ac.kr; | JOURNAL OF STRUCTURAL BIOLOGY | J STRUCT BIOL | 1047-8477 | 1095-8657 | 217 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOPHYSICS;CELL BIOLOGY | 2024 | 2.7 | 42.4 | 0 | 2025-05-07 | 0 | 0 | Isocitrate dehydrogenase; Allosteric regulation; Oxaloacetate; Conformational change | OXIDATIVE DAMAGE; CELLULAR DEFENSE; OXALOMALATE; GLYOXYLATE; MECHANISM; EXPRESSION; REDUCTION | Allosteric regulation; Conformational change; Isocitrate dehydrogenase; Oxaloacetate | Allosteric Regulation; Animals; Catalytic Domain; Crystallography, X-Ray; Cytosol; Isocitrate Dehydrogenase; Isocitrates; Mice; Models, Molecular; Mutation; NADP; Oxaloacetic Acid; isocitrate dehydrogenase (NADP); isocitric acid; magnesium ion; oxaloacetic acid; Idh1 protein, mouse; isocitrate dehydrogenase; nicotinamide adenine dinucleotide phosphate; oxaloacetic acid; allosterism; Article; crystal structure; dimerization; drug targeting; enzyme active site; enzyme activity; enzyme inhibition; human; mouse; nonhuman; allosterism; animal; chemistry; cytosol; enzymology; genetics; metabolism; molecular model; mutation; X ray crystallography | English | 2025 | 2025-06 | 10.1016/j.jsb.2025.108183 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Characterisation of the CRISPR-Cas systems in Enterococcus faecalis from commercial broiler farm environments and its association with antimicrobial resistance | 1. Clustered regularly interspaced short palindromic repeats (CRISPR)-associated proteins (Cas) systems have been highlighted for their potential applications in controlling the spread of mobile genetic elements, including antimicrobial resistance (AMR) genes. This study investigated the characteristics of CRISPR-Cas systems in E. faecalis from commercial broiler farms and assessed the impact of these systems on AMR. 2. All E. faecalis isolates contained CRISPR2, and CRISPR1-Cas and CRISPR3-Cas were identified in 84 (56.4%) and 144 (96.6%) isolates. A combination of CRISPR2 and CRISPR3-Cas and a combination of CRISPR1-Cas, CRISPR2 and CRISPR3-Cas were each identified in 27 (96.4%) farms. 3. There were significant differences between CRISPR-Cas systems for phenotypic AMR: CRISPR1-Cas and CRISPR3-Cas. The E. faecalis isolates without CRISPR1-Cas showed higher resistance to most antimicrobials and had a higher prevalence of multidrug resistance (MDR) than those with CRISPR1-Cas. However, the resistance rate against most antimicrobials and the prevalence of MDR did not differ significantly depending on the presence or absence of CRISPR3-Cas. 4. The E. faecalis isolates without CRISPR1-Cas harboured higher levels of all AMR genes, except for tetL, than those with CRISPR1-Cas. However, the E. faecalis isolates with CRISPR3-Cas showed a significant lower prevalence of tetL gene and a significantly higher prevalence of fexA and poxtA genes. 5. In the distribution of rep families, the rep9 family was predominant, followed by rep1, rep7, rep2 and rep8 families. Only prevalence of the rep7 family was significantly higher in the E. faecalis isolates without CRISPR1-Cas (15.4%) than in those with CRISPR1-Cas (0%). 6. This study is the first report on the characteristics of CRISPR-Cas systems in E. faecalis isolated from commercial broiler farm environments, and the results supported the hypothesis that the development of antimicrobial strategies requires an understanding of the distinctive capabilities between CRISPR1-Cas and CRISPR3-Cas and their underlying resistance mechanisms. © 2025 British Poultry Science Ltd. | Kim, M.B.; Lee, Y.J. | College of Veterinary Medicine & Institute for Veterinary Biomedical Science, Kyungpook National University, Daegu, South Korea; College of Veterinary Medicine & Institute for Veterinary Biomedical Science, Kyungpook National University, Daegu, South Korea | 58891566600; 56612134500 | youngju@knu.ac.kr; | British Poultry Science | BRIT POULTRY SCI | 0007-1668 | 1466-1799 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE | 2024 | 1.7 | 42.4 | 0 | 2025-05-07 | 1 | antimicrobial resistance; broiler; CRISPR-Cas system; Enterococcus faecalis; plasmid | English | Article in press | 2025 | 10.1080/00071668.2025.2451268 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Oxidation-Condensation Tandem Catalysis via a Multifunctional Cu-Based Metal-Organic Framework | The development of heterogeneous catalysts for tandem reactions remains a significant challenge for practical applications, primarily due to the need for multiple isolated catalytic sites. This study presents a novel metal-organic framework (MOF), Cu-AIPA, formulated as Cu(AIPA)(DMF)2 (AIPA: 2-amino isophthalic acid, DMF: N, N-dimethylformamide). The Cu-AIPA framework integrates three distinct catalytic mechanisms: redox activity, Br & oslash;nsted basicity, and Lewis acidity. The structure of Cu-AIPA features redox-active Cu(II) centers and Br & oslash;nsted basic sites, enabling the sequential transformation of alcohols to aldehydes and their subsequent condensation into imines. The close spatial arrangement of these redox-active/Lewis acidic and basic sites within the confined pores of Cu-AIPA facilitates efficient tandem catalysis. This process involves oxidizing benzyl alcohol to benzaldehyde using TEMPO without requiring an external base, followed by amine condensation. Compared with HKUST-1, another Cu-based MOF with a high surface area, Cu-AIPA demonstrated superior catalytic performance at room temperature. Recyclability tests revealed that Cu-AIPA retained over 90 % conversion efficiency across at least three catalytic cycles. This study highlights the potential of MOFs incorporating multiple catalytic sites and confined pore structures for tandem reactions, emphasizing their potential for scalable and sustainable industrial applications. | Kim, Hyeonsu; Son, Younghu; Hwang, Dogyeong; Rao, Purna Chandra; Kim, Younghoon; Yoon, Minyoung | Kyungpook Natl Univ, KNU Inst Basic Sci, KNU G LAMP Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Korea Res Inst Chem Technol KRICT, Ctr Biobased Chem, Ulsan 44429, South Korea | Son, Younghu/AAX-9531-2021; Rao, Purna Chandra/AHI-3532-2022; Hwang, Dogyeong/MYR-7932-2025 | 59866845900; 57216839175; 59557038000; 56378818800; 57194503957; 25222186500 | myyoon@knu.ac.kr; | CHEMISTRY-AN ASIAN JOURNAL | CHEM-ASIAN J | 1861-4728 | 1861-471X | 20 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2024 | 3.3 | 42.5 | 0 | 2025-05-07 | 0 | 0 | Metal-organic framework; Tandem catalysis; Oxidation; Condensation; Multifunctional MOF | Condensation; Metal-organic framework; Multifunctional MOF; Oxidation; Tandem catalysis | Ascorbic acid; Catalysis; Catalytic oxidation; Condensation reactions; Ionization of gases; Metal-Organic Frameworks; Redox reactions; alcohol; alcohol derivative; aldehyde; amine; benzaldehyde; benzyl alcohol; cupric ion; imine; isophthalic acid; metal organic framework; n,n dimethylformamide; Basic sites; Catalytic sites; Cu-based; Metalorganic frameworks (MOFs); Multifunctional metal-organic framework; Multifunctionals; Redox-active; Tandem catalysis; Tandem reaction; acidity; article; catalysis; catalyst; controlled study; oxidation; room temperature; surface area; Dimethylformamide | English | 2025 | 2025-05-02 | 10.1002/asia.202401614 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhancing the performance of cold-setting phenol-resorcinol-formaldehyde resin adhesives through condensation extension | Phenol-resorcinol-formaldehyde (PRF) are the most essential adhesives for laminated timber products. PRF resins are known for their excellent strength and durability. However, when cold-pressed, PRF resins have various issues, including free phenol in the resin solution, which cannot react with formaldehyde. Aside from decreasing reactivity, excessive amounts of free phenol will render PRF resins hazardous. In addition, using hardeners containing significant amounts of paraformaldehyde might result in high formaldehyde emissions if the resin and hardener do not react completely during curing. Therefore, this research aims to reduce the possibility of high levels of free phenol and formaldehyde in PRF resins by synthesizing the resins with various condensation times and using an oxazolidine hardener to replace paraformaldehyde. PRF resins' properties and adhesion performance with various condensation times were evaluated. The results showed that PRF resins' viscosity and solids content increased when the condensation time increased, whereas their gelation time reduced. PRF resins with a longer condensation time had a higher proportion of methylene linkage and greater reactivity, as evidenced by lower apparent activation energy during curing. Furthermore, increasing the condensation time of PRF resins enhanced the adhesion strength of glue-laminated timber products bonded with these resins. The results showed that increasing the condensation time of PRF resins significantly impacts their reactivity and performance. | Wibowo, Eko Setio; Park, Byung-Dae; Lubis, Muhammad Adly Rahandi; Kusumah, Sukma Surya; Santoso, Adi; Sari, Ajeng Arum; Iswanto, Apri Heri | Natl Res & Innovat Agcy, Res Ctr Biomass & Bioprod, Bogor 16911, Indonesia; Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea; Natl Res & Innovat Agcy, Directorate Res & Innovat Funding, Gedung BJ Habibie Jl MH Thamrin 8, Jakarta 10340, Indonesia; Univ Sumatera Utara, Fac Forestry, Dept Forest Prod, Medan 20155, Indonesia | Wibowo, Eko/AAL-5888-2021; Park, Byung-Dae/ABB-1934-2020; Lubis, Muhammad/K-2440-2019; kusumah, sukma/AAW-7634-2021; Santoso, Adi/S-7299-2016; Iswanto, Apri/ABA-5024-2021 | 57214910272; 7402834820; 57192278476; 57096020000; 58904957000; 55212494400; 58252090200 | apri@usu.ac.id; | INTERNATIONAL JOURNAL OF ADHESION AND ADHESIVES | INT J ADHES ADHES | 0143-7496 | 1879-0127 | 138 | SCIE | ENGINEERING, CHEMICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.5 | 42.6 | 0 | 2025-05-07 | 0 | 0 | Cold-setting adhesives; PRF resins; Glue laminated timber; Reactivity; Cure kinetics; Adhesion | THERMAL-BEHAVIOR; KINETICS | Adhesion; Cold-setting adhesives; Cure kinetics; Glue laminated timber; PRF resins; Reactivity | Activation Energy; Condensation; Gelation; Gluing; Paraformaldehyde; Performance; Phenol; Reactivity; Gelation; Glues; Gluing; Timber; Cold-setting; Cold-setting adhesive; Cure kinetics; Glue-laminated timber; Performance; Phenol resorcinol formaldehydes; Phenol–resorcinol–formaldehyde resin; Reactivity; Resorcinol formaldehyde resin; Timber products; Activation energy | English | 2025 | 2025-03 | 10.1016/j.ijadhadh.2025.103958 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Evaluating the differences of adhesion strength between mussel-inspired and conventional soy protein adhesives: A critical review | The quest for sustainable and high-performance adhesives has driven extensive research into bio-based alternatives, with soy protein (SP) emerging as a promising candidate. Inspired by the remarkable adhesion mechanisms of marine mussels, recent studies have explored biomimetic strategies-such as dual crosslinking, organic-inorganic hybridization, and sacrificial bond mechanisms-to enhance the bonding strength and water resistance of SP-based adhesives. This review examines the effectiveness of these mussel-inspired modifications compared to conventional crosslinking approaches in SP adhesives. Surprisingly, the improvements in adhesive performance, particularly in terms of bonding strength and water resistance, were only marginally superior to those achieved through non-biomimetic modifications. This finding suggests that while musselinspired strategies offer valuable insights, further refinement is necessary to fully harness their potential. Specific technical directions, such as designing SP-specific mussel-inspired peptide segments, incorporating catecholfunctionalized crosslinkers, and optimizing redox-responsive or pH-sensitive bonding mechanisms, represent promising routes for improvement. By critically evaluating these approaches, this review also highlights opportunities for advancing SP-based adhesives through novel crosslinking techniques, cost-effective formulations, and processing methods. The insights provided herein pave the way for future innovations in bio-based adhesives. | Supianto, Mulya; Wibowo, Eko Setio; Lubis, Muhammad Adly Rahandi; Kusumah, Sukma Surya; Sutiawan, Jajang; Yadav, Sumit Manohar; Park, Byung-Dae | Natl Res & Innovat Agcy, Res Ctr Biomass & Bioprod, Bogor 16911, Indonesia; Forest Coll & Res Inst, Dept Forest Prod & Utilizat, Hyderabad, India; Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea | ; Lubis, Muhammad/K-2440-2019; kusumah, sukma/AAW-7634-2021; Supianto, Mulya/KIH-9760-2024; Wibowo, Eko/AAL-5888-2021; Park, Byung-Dae/ABB-1934-2020; Sutiawan, Jajang/ABA-9111-2021 | 57304127400; 57214910272; 57192278476; 57096020000; 57219222772; 57191834292; 59874304100 | ekos009@brin.go.id; | INTERNATIONAL JOURNAL OF ADHESION AND ADHESIVES | INT J ADHES ADHES | 0143-7496 | 1879-0127 | 141 | SCIE | ENGINEERING, CHEMICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.5 | 42.6 | 0 | 2025-06-11 | 0 | 0 | Soy protein; Adhesives; Mussel-inspired adhesives; Protein backbone; Bond strength; Water resistance | SACRIFICIAL BONDS; TOUGHNESS | Adhesives; Bond strength; Mussel-inspired adhesives; Protein backbone; Soy protein; Water resistance | Adhesion; Adhesives; Bonding Strength; Gluing; Peeling; Performance; Review; Water Resistance; Bond strength (materials); Crosslinking; Gluing; Peeling; Bio-based; Bond strength; Bonding strength; Critical review; Mussel-inspired adhesive; Performance; Protein backbone; Soy protein; Soy protein adhesives; Water-resistances; Glues | English | 2025 | 2025-08 | 10.1016/j.ijadhadh.2025.104059 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Investigation of thermal adaptability based on facial temperature and subjective evaluation indexes of during the use of HVAC in a summer office | Thermal adaptation is closely related to building energy, as the process of thermal adaptation within a building can influence energy consumption and efficiency. This study was aimed at analyzing thermal adaptation using subjective evaluation indexes of occupants and facial temperature data in a centralized control system building. Conducted during the summer in an office with a centralized HVAC system, this study utilized Thermal Sensation Vote (TSV), Thermal Comfort Vote (TCV), and Temperature Sensation Index (TSI) as subjective evaluation indices. The results indicated that occupants required, on average, 30 min to achieve thermal adaptation. A facial temperature of 34 degrees C before thermal adaptation indicated discomfort, whereas the same facial temperature after thermal adaptation indicated comfort. These findings highlight the importance of considering thermal adaptation in HVAC design, as efficient thermal management can significantly impact energy consumption. Incorporating thermal adaptation strategies into HVAC systems could improve energy efficiency while enhancing occupant comfort. Therefore, when predicting thermal comfort in future buildings, it is essential to consider both the thermal adaptation of occupants and subjective evaluation indices alongside physiological signals. | Kim, Sung-Kyung; Ryu, Jihye; Seo, Hyuncheol; Hong, Won-Hwa | Kyungpook Natl Univ, Convergence Inst Construct Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea | 57196459261; 56192651000; 56083741500; 7401527968 | kimsg1012@knu.ac.kr; ryou0407@knu.ac.kr; charles@knu.ac.kr; hongwh@knu.ac.kr; | ENERGY REPORTS | ENERGY REP | 2352-4847 | 13 | SCIE | ENERGY & FUELS | 2024 | 5.1 | 42.6 | 0 | 2025-05-07 | 0 | 0 | Centralized control system; HVAC; Subjective evaluation index; Facial skin temperatures; Thermal adaptation; Thermal comfort; Buildings | SKIN TEMPERATURE; COMFORT; PREDICTION; SENSATION; RESPONSES; BODY | Buildings; Centralized control system; Facial skin temperatures; HVAC; Subjective evaluation index; Thermal adaptation; Thermal comfort | Thermal comfort; Centralized control systems; Energy-consumption; Evaluation index; Facial Skin temperature; HVAC system; Subjective evaluation index; Subjective evaluations; Thermal; Thermal adaptabilities; Thermal adaptation; Thermal efficiency | English | 2025 | 2025-06 | 10.1016/j.egyr.2025.04.042 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
