| ○ | ○ | Article | Near-Infrared-Sensing Flexible Organic Synaptic Transistors with Water-Processable Charge-Trapping Polymers for Potential Neuromorphic Computing/Skin Applications | Neuromorphic devices, which can mimic the human body's neural system, are rising as an essential technology for artificial intelligence. Here, two types of organic synaptic transistors (OSTRs), OSTR-A and OSTR-B, are fabricated on either glass or polymer film using water-processable charge-trapping gate-insulating layers that are prepared by reacting ethylenediamine (EDA) and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA). OSTR-A is designed to function as a basic artificial synapse by gate pulse stimulation only, while OSTR-B has additional near-infrared (NIR)-absorbing conjugated polymer layers for further sensing of NIR light upon gate voltage stimulations. The PAMPSA:EDA films are found to contain permanent charge bridges (ion pairs of -SO3- +NH3-) that play a charge-trapping role in OSTRs. Both devices with the PAMPSA:EDA layers exhibit clear postsynaptic current (PSC) signals upon gate voltage pulses, leading to long-term potentiation/depression characteristics. The flexible OSTR-B devices can sense the NIR light (905 nm) upon gate pulse stimulation and their PSC signals are well maintained even after bending (>5000 times). Artificial neural network simulations disclose that the flexible OSTR-B devices can stably perform synaptic operations under the NIR light with high accuracy (>90%) even after repeated bending (5000 times), indicative of potential use in artificial neuromorphic skin applications. | Kim, Taehoon; Lee, Woongki; Kim, Soyeon; Lim, Dong Chan; Kim, Youngkyoo | Kyungpook Natl Univ, Organ Nanoelect Lab, Dept Chem Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Inst Nanophoton Applicat KINPA, Dept Chem Engn, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Dept Energy & Elect Mat, Surface Mat Div, Chang Won 51508, South Korea; Korea Inst Mat Sci KIMS, Nano Technol Innovat Ctr, Chang Won 51508, South Korea | ; Kim, Taehoon/ABF-7433-2021 | 57218650958; 59041346100; 57069276700; 8526402700; 10340424400 | kimso1965@kims.re.kr;dclim@kims.re.kr;ykimm@knu.ac.kr; | ADVANCED INTELLIGENT SYSTEMS | ADV INTELL SYST-GER | 2640-4567 | 6 | 4 | SCIE | AUTOMATION & CONTROL SYSTEMS;COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ROBOTICS | 2024 | 6.1 | 13.5 | 1.42 | 2025-05-07 | 5 | 5 | artificial neural networks; charge trapping; flexible organic synaptic transistors; neuromorphic; water processable | CONTINUUM ROBOTS; ORIGAMI; DESIGN; ARM | artificial neural networks; charge trapping; flexible organic synaptic transistors; neuromorphic; water processable | Ammonia; Charge trapping; Conjugated polymers; Infrared devices; Intelligent systems; Polymer films; Semiconducting films; Threshold voltage; Charge-trapping; Ethylene diamine; Flexible organic synaptic transistor; Near Infrared; Near infrared light; Near-infrared; Neuromorphic; Organics; Processable; Water processable; Neural networks | English | 2024 | 2024-04 | 10.1002/aisy.202300651 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | pH-responsive chitosan/poly (vinyl pyrrolidone) based hydrogel composites: Antibacterial properties and release kinetics of diclofenac sodium | Development of effective hydrogels based anti-inflammatory drug delivery materials remains great challenge. In this study, diclofenac sodium (DS) was successfully encapsulated into chitosan (CS)/poly (vinyl pyrrolidone) (PVP) with glutaraldehyde crosslinked hydrogels. The characteristics of the hydrogel composites were characterized by swelling behavior, FTIR spectroscopy, hydrophilicity, and porosity test, SEM-EDX, X-ray diffraction, thermal stability, and mechanical strength methods. pH-dependent drug (DS) release behavior and the antibacterial activity of the hydrogel composites were examined. Typically, the interaction of polymer precursors, crosslinker, and drug compound occurred via hydrogen bonding. The cross-sectional SEM images demonstrated the pore formation in hydrogel matrix. Mechanical properties of hydrogel improved from 8.9 to 13.1 MPa due to crosslinking process and DS encapsulation. Insertion of diclofenac sodium improved the hydrophilicity as shown in the lowering of contact angle to 55.47(degrees). Hydrogel samples showed promising antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus with the zone of inhibition (ZoI) up to 21.8 +/- 0.05 mm and 18.7 +/- 0.09 mm, respectively. The controlled DS release from hydrogel composites at pH 4, 7 and 10 has maximum release amount of approximately around 10 %, 80 %, and 90 %, respectively. The kinetics and mechanism of drug release from hydrogels was followed Kosmeyer-Peppas and Higuchi models, indicating that the DS release from hydrogel was predominantly controlled by Fickian diffusion or swelling process. These results indicated that the pH-responsive hydrogels based on CS/PVP can be a promising candidate for drug delivery due to its high susceptibility to antibacterial activity. | Khoerunnisa, Fitri; Yolanda, Yustika Desti; Nurhayati, Mita; Hendrawan, Hendrawan; Sanjaya, Eli Hendrik; Triwardono, Joko; Astuti, Wijayanti Dwi; Handayani, Murni; Da Oh, Wen; Ooi, Boon Seng | Indonesia Univ Educ, Grad Program Chem, Bandung 40154, Indonesia; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju Si, Gyeongsangbuk D, South Korea; Univ Negeri Malang, Chem Dept, Malang 65145, Indonesia; Natl Res & Innovat Agcy BRIN, Res Ctr Met, Banten 15314, Indonesia; Univ Gadjah Mada, Vocat Coll, Dept Elect Engn & Informat, Yogyakarta 55281, Indonesia; Natl Res & Innovat Agcy BRIN, Res Ctr Adv Mat, Tangerang Selatan, Indonesia; Univ Sains Malaysia, Sch Chem Sci, George Town 11800, Malaysia; Univ Sains Malaysia, Sch Chem Engn, Engn Campus, Seri Ampangan 14300, Nibong, Malaysia | Ooi, BoonSeng/NGQ-6921-2025; Sanjaya, Eli/ABE-4082-2021; Nurhayati, Mita/GOJ-8523-2022; Khoerunnisa, Fitri/GOJ-8479-2022; Hendrawan, Hendrawan/GOJ-8304-2022; Astuti, Wijayanti/AAL-1006-2021; Handayani, Murni/AAV-8997-2020 | 36675148400; 57404973400; 57222139830; 6506917385; 57191636626; 57214135764; 57219245152; 57202087591; 57205433398; 59466017900 | fitri@upi.edu;ohwenda@usm.my;chobs@usm.my; | JOURNAL OF DRUG DELIVERY SCIENCE AND TECHNOLOGY | J DRUG DELIV SCI TEC | 1773-2247 | 2588-8943 | 92 | SCIE | PHARMACOLOGY & PHARMACY | 2024 | 4.9 | 13.5 | 1.96 | 2025-05-07 | 2 | 4 | Chitosan/poly (vinyl pyrrolidone); Hydrogels; Diclofenac sodium; Drug -controlled release; pH -sensitive | DELIVERY-SYSTEM | Chitosan/poly (vinyl pyrrolidone); Diclofenac sodium; Drug-controlled release; Hydrogels; pH-sensitive | 1 vinyl 2 pyrrolidinone; chitosan; diclofenac; glutaraldehyde; hydrogel; polymer; povidone; antibacterial activity; Article; channel gating; chemical interaction; contact angle; controlled study; cross linking; deacetylation; drug release; encapsulation; Fourier transform infrared spectroscopy; hydrogen bond; hydrophilicity; kinetics; nanoencapsulation; nonhuman; pH; porosity; Pseudomonas aeruginosa; scanning electron microscopy; Staphylococcus aureus; surface property; synthesis; tensile strength; thermostability; ultraviolet spectrophotometry; X ray diffraction; zone of inhibition | English | 2024 | 2024-02 | 10.1016/j.jddst.2023.105308 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Si-Based Dual-Gate Field-Effect Transistor Array for Low-Power On-Chip Trainable Hardware Neural Networks | Herein, dual-gate field-effect transistors (DG FETs) fabricated on Si substrate and a corresponding NOR-type array designed for low-power on-chip trainable hardware neural networks (HNNs) are presented. The fabricated DG FET exhibits notable endurance characteristics, with the subthreshold swing remaining consistently within a 2.45% range of change and Delta Vth per cycle maintaining stability at 4.5% over repetitive program and erase operations, up to 104 cycles. Furthermore, a multilevel characteristic is achieved through low-power program/erase operations based on Fowler-Nordheim (FN) tunneling, which exhibit 0.09 and 0.99 fJ per spike, respectively. These characteristics provide the HNN stability, along with high performance and power efficiency. The NOR-type array in this work demonstrates selective update and bidirectional vector-by-matrix multiplication capabilities. This enables on-chip training based on a gradient descent algorithm, without the need for an additional array for backpropagation. Subsequently, a simulation of the Modified National Institute of Standards and Technology classification is conducted to evaluate the accuracy and training power consumption of the proposed device in comparison to other two-terminal memristor devices. The results show that the DG FET array achieves superior accuracy while maintaining over 180.4 times higher energy efficiency, demonstrating the potential of the DG FET as a promising candidate for low-power HNN applications. Herein, dual-gate field-effect transistors (DG FETs) for low-power on-chip hardware neural networks (HNNs) are reported. The saturation characteristic of the device provides robustness against voltage fluctuations. The NOR-type DG FET array is capable of both bidirectional operation and selective updates based on Fowler-Nordheim tunneling, reducing the latency and power consumption during the training phase of the on-chip trainable HNNs.image (c) 2023 WILEY-VCH GmbH | Lee, Kyu-Ho; Kwon, Dongseok; Lee, In-Seok; Hwang, Joon; Im, Jiseong; Bae, Jong-Ho; Choi, Woo Young; Woo, Sung Yun; Lee, Jong-Ho | Seoul Natl Univ, Dept Elect & Comp Engn, 1 Gwanak Ro, Seoul 08826, South Korea; Seoul Natl Univ, Interuniv Semicond Res Ctr, 1 Gwanak Ro, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Kookmin Univ, Sch Elect Engn, 77 Jeongneung Ro, Seoul 02707, South Korea | ; Bae, Jong-Ho/V-5237-2019; Choi, Woo Young/ACK-4652-2022; Lee, Jingyu/AAV-8920-2020; Kwon, Dongseok/JDC-8584-2023 | 57919620700; 57203288190; 58104753500; 57224668810; 57224201303; 55339347700; 7402516430; 57201527826; 57221622173 | sywoo@knu.ac.kr;jhl@snu.ac.kr; | ADVANCED INTELLIGENT SYSTEMS | ADV INTELL SYST-GER | 2640-4567 | 6 | 1 | SCIE | AUTOMATION & CONTROL SYSTEMS;COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ROBOTICS | 2024 | 6.1 | 13.5 | 1.18 | 2025-04-16 | 3 | 3 | dual-gate field-effect transistors; gradient descent algorithms; hardware-based neural networks; NOR-type arrays; on-chip training | FLASH MEMORY; DEVICE; OXIDE; FILM; ARCHITECTURE | dual-gate field-effect transistors; gradient descent algorithms; hardware-based neural networks; NOR-type arrays; on-chip training | Field effect transistors; Gradient methods; Intelligent systems; Low power electronics; Neural networks; Silicon; Dual gates; Dual-gate field-effect transistor; Gradient descent algorithms; Hardware neural networks; Hardware-based neural network; Low Power; Neural-networks; NOR-type array; On chips; On-chip training; Energy efficiency | English | 2024 | 2024-01 | 10.1002/aisy.202300490 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Achieving high durability in all-solid-state lithium metal batteries using metal-organic framework solid polymer electrolytes | Solid-state polymer electrolytes (SPEs) possess several favorable properties, such as high flexibility, easy processability, and better safety for batteries. Thus, SPEs are attracting considerable attention for the development of safer Li ion batteries. However, SPEs typically lack the required ionic conductivity for improved Li+ transportation. Therefore, suitable fillers are often used to prepare composite polymer electrolytes (CPEs) with improved ionic conductivity. In this direction, a novel CPE with increased electrochemical stability and durability was prepared by incorporating highly porous Zr-based metal-organic frameworks (MOFs), herein referred to as ZR8, as fillers in poly(ethylene oxide) (PEO)/Li salt systems. PEO in the prepared CPE showed low crystallization ratios, and the CPE showed enhanced Li+ ion transportation, thereby improving mechanical and fire-retardant properties. It was also able to hinder Li dendrite formation and eventually facilitated efficient transport of Li+ ions through the electrolyte. A high specific surface area, the presence of Lewis acid-base sites, and good thermal and chemical stability of the ZR8 filler contributed to the improved electrolyte performance. CPE prepared with 7.5% ZR8 fillers showed a good ionic conductivity of 2.53 x 10-4 S cm-1 at 30 degrees C and 1.35 x 10-3 S cm-1 at 60 degrees C and an electrochemical window of similar to 5.58 V. The [Li|ZR8-7.5|Li] cell showed an excellent stability in 8000-h operation without any flaw (at 60 degrees C and a current density of 100 mu A cm-2). Additionally, the [Li|ZR8-7.5|LFP] cell was able to retain over 80% of its initial capacity (144.9 mA h g-1 at 0.5C) even after 800 cycles. The addition of MOF-808 to a solid polymer electrolyte (SPE) successfully controls the growth of lithium dendrites. This accomplishment was attained through a straightforward approach and resulted in exceptional electrochemical properties. | Kim, Suin; Jamal, Hasan; Khan, Firoz; Al-Ahmed, Amir; Abdelnaby, Mahmoud M.; Al-Zahrani, Atif; Chun, Sang-Eun; Kim, Jae Hyun | Daegu Gyeongbuk Inst Sci & Technol, Div Energy Technol, 333,Techno Jungang-Daero,Hyeonpung-Myeon, Daegu 42988, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; King Fahd Univ Petr & Minerals KFUPM, Interdisciplinary Res Ctr Sustainable Energy Syst, Dhahran 31261, Saudi Arabia; King Fahd Univ Petr & Minerals KFUPM, Interdisciplinary Res Ctr Hydrogen & Energy Storag, Dhahran 31261, Saudi Arabia | Al-Ahmed, Amir/B-4489-2011; Alzahrani, Atif/LLK-2080-2024; Jamal, Hasan/GNO-9249-2022; Khan, Firoz/G-8959-2019; Abdelnaby, Mahmoud/A-9957-2018; Kim, Jae/AAY-8167-2020; chun, sang-eun/I-7271-2012 | 58291821900; 57222123834; 58261766200; 15758850600; 8642015900; 59125781500; 36801080300; 57192648482 | sangeun@knu.ac.kr;jaehyun@dgist.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 12 | 18 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 9.5 | 13.6 | 2.02 | 2025-05-07 | 10 | 10 | IONIC-CONDUCTIVITY; TEMPERATURE-RANGE; HIGH-VOLTAGE; MEMBRANE; FILLER; MECHANISMS; STABILITY | Chemical stability; Durability; Ethylene; Fillers; Ionic conduction in solids; Ions; Lithium-ion batteries; Organometallics; Polyelectrolytes; Polyethylene oxides; Solid electrolytes; Solid-State Batteries; All-solid state; Composite polymer electrolytes; Framework solids; High durability; Li +; Lithium metals; Metalorganic frameworks (MOFs); Polymer electrolyte; Property; Solid polymer electrolytes; Ionic conductivity | English | 2024 | 2024-05-08 | 10.1039/d3ta07184g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Counterion chemistry of 5-halo (X: Cl, Br, I)-uracil derived carbon nitride: unlocking enhanced photocatalytic performance | The performance of modified polymeric carbon nitride (PCN) photocatalysts exceeds that of their bulk counterparts, owing to their distinct advantages and enhanced features. In this work, we present the synthesis methodology for halide-molecular doped PCN through a single molecule precursor approach by combining pi-aromatic uracil and halide as a dopant and counterions, respectively. We systematically investigated the effect of halide ions (X-: Cl-, Br-, and I-) on the photoactivity of 5-halouracil derived PCN (XUCN). Our results demonstrate that halide counterions significantly enhance the photocatalytic activity of XUCN for hydrogen peroxide and hydrogen production (126.6 mu mol h-1 and 0.563 mmol h-1 g-1), compared to the undoped bulk PCN (48.3 mu mol h-1 and 0.260 mmol h-1 g-1). The charge-carrier analysis and structural analysis of synthesized XUCN catalysts suggest that the improvement in photoactivity is due to the synergistic interactions of uracil and halide ions, which enhance the charge-carrier lifetime (1.51 to 3.08 ns), generate additional catalytic sites (10.6 to 83.3 m2 g-1), and extend light absorption (450 to 480 nm). Theoretical investigations reveal high structural stability for XUCN with favourable adsorption energies to bind with reactive oxygen species. The new insights provided in this study can have important implications for future design and synthesis of metal-free PCN with improved photoactivity via single molecule precursor doping. This study presents the design of a halouracil doped polymeric carbon nitride photocatalyst with tunable optoelectronic properties and photoactivity. | Bhoyar, Toshali; Abraham, B.

| ○ | Article | Enhancing the performance of indoor organic photovoltaics through precise modulation of chlorine density in wide bandgap random copolymers | We present highly efficient indoor organic photovoltaic (IOPV) devices based on a series of four wide-bandgap random copolymers, denoted as B30T70-XCl (X = 0, 2, 4 and 6). The absorption range of these copolymers efficiently covers the spectral range of indoor light sources, with a systematic decrease in the HOMO levels based on the number of chlorine atoms (0 > 2 > 4 > 6Cl). The introduction of Cl is an effective and cost-efficient strategy because of the simplicity of the synthesis. We use PC71BM as the electron acceptor, which not only effectively absorbs indoor light spectra, but also significantly reduces production costs compared with state-of-the-art non-fullerene acceptors (NFAs). Among the B30T70-XCl:PC71BM blends, the B30T70-2Cl-based devices exhibit optimized power conversion efficiencies (PCEs) with a high V-OC, achieving a record-breaking PCE of 25.0% under fluorescent lamp (FL) illumination, compared with reported fullerene-based IOPVs. Through a comprehensive analysis of the energy levels, transient absorption dynamics, and blend morphology, we reveal that increasing the Cl density decreases the HOMO offset between the polymer donors and the PC71BM acceptor and induces a phase-separated blend morphology, critically impacting the performance of IOPVs by influencing the population of charge-separated states and charge transport behavior, respectively. The performance of these IOPVs based on wide-bandgap random copolymers and the PC71BM acceptor suggests that the development of such classical, low-cost photoactive layer blends holds promise for integration into low-power portable electronics and Internet-of-Things (IoT) sensors. | Kim, Soyoung; Kim, Seon Joong; Ham, Gayoung; Jeong, Ji-Eun; Lee, Donghwa; Lee, Eunho; Ahn, Hyungju; Cha, Hyojung; Shim, Jae Won; Lee, Wonho | Kumoh Natl Inst Technol, Dept Polymer Sci & Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, Gyeongbuk, South Korea; Korea Univ, Sch Elect Engn, Seoul 02841, South Korea; Kyungpook Natl Univ, Dept Energy Convergence & Climate Change, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Korea Res Inst Chem Technol, Ctr Adv Specialty Chem, Ulsan 44412, South Korea; Kumoh Natl Inst Technol, Dept Chem Engn, Gumi 39177, South Korea; Pohang Accelerator Lab, Pohang 37673, South Korea | ; Lee, Wonho/K-9246-2016; Lee, Wonho/AAD-3358-2022; Lee, Eunho/D-6234-2014 | hcha@knu.ac.kr;jwshim19@korea.ac.kr;1holee@kumoh.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 12 | 5 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 9.5 | 13.6 | 4 | POLYMER SOLAR-CELLS; ENERGY-LEVEL MODULATION; ACCEPTOR; EFFICIENCY; DONOR; CHALLENGES; DESIGN; SENSOR | English | 2024 | 2024-01-30 | 10.1039/d3ta06624j | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Exactly regulated copper catalysts exploiting isolated photoelectrochemical reduction of cuprous oxides and random mesh-structured TiO2 for enhanced photoelectrochemical CO2 conversion | Photoelectrochemical (PEC) CO2 reduction for the direct conversion of solar energy into carbon-based chemical fuels has received considerable attention owing to it being an inherently sustainable and green process. However, complex photocathode architectures and processes involving protective layers and co-catalysts typically hinder product selectivity and stable PEC operation. Cu is the only electrocatalyst that yields products containing multiple carbon molecules during the electrochemical CO2 reduction reaction (CO2RR). In this study, Cu nanoparticles were artificially fabricated on the surface of Cu2O from a light absorption layer using isolated photoelectrochemical reduction, which was designed from a negative photocorrosive reaction. Using hydrogen evolution reaction (HER) and CO2RR electrolytes, HER-Cu (H-Cu) and CO2RR-Cu (C-Cu) catalysts were respectively fabricated by artificially controlling photoelectrochemical self-photocorrosion (SPC) at the atomic level. Additionally, we adopted a partially installed random-mesh (RM) structured protective TiO2 layer with ultimately thin thickness and the optimal structure displays resistant to photocorrosion by forming individual catalyst particles on the uncovered RM-TiO2. The designed Cu2O/RM-TiO2/H-Cu displays a remarkable cathodic-photocurrent density of -1.57 mA cm(-2) at 0.4 V-RHE, CO formation with 98% efficiency, and improved stability under illumination. The utilization of an RM-structured TiO2 layer mitigates loss of charge via recombination, while also imposing a physical barrier that restricts direct interaction between the Cu2O surface without the Cu catalyst and the electrolyte. This study provides mechanistic insights into the CO2RR pathways and suggests an innovative approach that exploits the intrinsic corrosion reaction to design efficient PEC CO-producing catalysts. | Oh, Shin Young; Kim, Dong Su; Lee, Hak Hyeon; Lee, Kun Woong; Choi, Ji Hoon; Yang, Won Seok; Choi, Young Su; Kim, Dong Wook; Byeon, Jee Won; Lee, Ho Seong; Cho, Hyung Koun | Sungkyunkwan Univ, Sch Adv Mat Sci & Engn, 2066 Seobu ro, Suwon 16419, Gyeonggi Do, South Korea; Sungkyunkwan Univ SKKU, Res Ctr Adv Mat Technol, 2066 Seobu ro, Suwon 16419, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak ro, Daegu 41566, South Korea | Cho, Hyung/P-2007-2017; 김, 동수/IAN-1770-2023 | 58514997000; 57209168253; 57923457900; 57255172600; 57218377818; 57895122500; 59140924000; 57822007300; 59140924100; 55706810400; 35236454300 | chohk@skku.edu; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 12 | 26 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 9.5 | 13.6 | 0.51 | 2025-05-07 | 1 | 2 | CARBON-DIOXIDE; CU2O PHOTOCATHODES; METHANOL | Carbon; Carbon dioxide; Copper oxides; Electrocatalysts; Electrolytes; Light absorption; Mesh generation; Photoelectrochemical cells; Reduction; Solar energy; Structural optimization; TiO2 nanoparticles; % reductions; CO 2 reduction; Cu catalyst; Cu catalysts; Cu-catalysts; Hydrogen evolution reactions; Mesh-structured; Photoelectrochemicals; Random meshes; Reduction reaction; Titanium dioxide | English | 2024 | 2024-07-02 | 10.1039/d4ta01486c | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Higher-order non-Markovian social contagions in simplicial complexes | Higher-order structures such as simplicial complexes are ubiquitous in numerous real-world networks. Empirical evidence reveals that interactions among nodes occur not only through edges but also through higher-dimensional simplicial structures such as triangles. Nevertheless, classic models such as the threshold model fail to capture group interactions within these higher-order structures. In this paper, we propose a higher-order non-Markovian social contagion model, considering both higher-order interactions and the non-Markovian characteristics of real-world spreading processes. We develop a mean-field theory to describe its evolutionary dynamics. Simulation results reveal that the theory is capable of predicting the steady state of the model. Our theoretical analyses indicate that there is an equivalence between the higher-order non-Markovian and the higher-order Markovian social contagions. Besides, we find that non-Markovian recovery can boost the system resilience to withstand a large-scale infection or a small-scale infection under different conditions. This work deepens our understanding of the behaviors of higher-order non-Markovian social contagions in the real world. High-order structures are ubiquitous in numerous real-world networks and play a significant role in social contagion phenomena, the authors introduce a novel higher-order non-Markovian social contagion model, addressing limitations of traditional models. Through mean-field theory and simulations, the authors demonstrate that there is an equivalence between the higher-order non-Markovian and the higher-order Markovian social contagions and reveal the resilience enhancement conferred by non-Markovian recovery, shedding light on real-world contagion dynamics. | Lin, Zhaohua; Han, Lilei; Feng, Mi; Liu, Ying; Tang, Ming | East China Normal Univ, Sch Phys & Elect Sci, Shanghai 200062, Peoples R China; Hong Kong Baptist Univ, Dept Phys, Kowloon Tong, Hong Kong, Peoples R China; Kyungpook Natl Univ, Nonlinear Dynam & Math Applicat Ctr, Dept Math, Daegu, South Korea; Southwest Petr Univ, Sch Comp Sci, Chengdu 610500, Peoples R China; East China Normal Univ, Shanghai Key Lab Multidimens Informat Proc, Shanghai 200241, Peoples R China | Han, Lilei/LLK-5681-2024; Feng, Mi/JFA-3680-2023 | 57216759524; 57216767091; 57210735678; 56641911300; 14421628700 | tangminghan007@gmail.com; | COMMUNICATIONS PHYSICS | COMMUN PHYS-UK | 2399-3650 | 7 | 1 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2024 | 5.8 | 13.6 | 2.82 | 2025-05-07 | 9 | 9 | MODELS; NETWORKS; MOBILITY | Complex networks; High-dimensional; High-order; High-order structure; Higher-dimensional; Higher-order; Higher-order structure; Non-Markovian; Real-world; Real-world networks; Simplicial complex; Mean field theory | English | 2024 | 2024-06-01 | 10.1038/s42005-024-01666-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Impact of the life-sustaining treatment decision act on organ donation in out-of-hospital cardiac arrests in South Korea: a multi-centre retrospective study | BackgroundThe demand for organ transplants, both globally and in South Korea, substantially exceeds the supply, a situation that might have been aggravated by the enactment of the Life-Sustaining Treatment Decision Act (LSTDA) in February 2018. This legislation may influence emergency medical procedures and the availability of organs from brain-dead donors. This study aimed to assess LSTDA's impact, introduced in February 2018, on organ donation status in out-of-hospital cardiac arrest (OHCA) patients in a metropolitan city and identified related factors.MethodsWe conducted a retrospective analysis of a regional cardiac arrest registry. This study included patients aged 16 or older with cardiac arrest and a cerebral performance category (CPC) score of 5 from January 2015 to December 2022. The exclusion criteria were CPC scores of 1-4, patients under 16 years, and patients declared dead or transferred from emergency departments. Logistic regression analysis was used to analyse factors affecting organ donation.ResultsOf the 751 patients included in this study, 47 were organ donors, with a median age of 47 years. Before the LSTDA, there were 30 organ donations, which declined to 17 after its implementation. In the organ donation group, the causes of cardiac arrest included medical (34%), hanging (46.8%), and trauma (19.2%). The adjusted odds ratio for organ donation before the LSTDA implementation was 6.12 (95% CI 3.09-12.12), with non-medical aetiology as associated factors.ConclusionThe enactment of the LSTDA in 2018 in South Korea may be linked to reduced organ donations among patients with OHCA, underscoring the need to re-evaluate the medical and legal aspects of organ donation, especially considering end-of-life care decisions. | Kim, Min Jae; Lee, Dong Eun; Kim, Jong Kun; Yeo, In Hwan; Jung, Haewon; Kim, Jung Ho; Jang, Tae Chang; Lee, Sang-Hun; Park, Jinwook; Kim, Deokhyeon; Ryoo, Hyun Wook | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Emergency Med, Daegu, South Korea; Catholic Univ Daegu, Sch Med, Dept Emergency Med, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Emergency Med, Sch Med, Daegu, South Korea; Daegu Fatima Hosp, Dept Emergency Med, Daegu, South Korea; Daegu Emergency Med Collaborat Comm, Daegu, South Korea | ; Yeo, Inhwan/GXZ-7024-2022; Lee, Dong Eun/HTN-4501-2023; Kim, Jung Ho/LDE-9088-2024 | 59310587800; 57202299238; 55915816900; 57216816807; 57221554827; 57205704177; 57189297849; 57210919228; 59311457300; 59310587900; 55350557500 | delee@knu.ac.kr; | BMC MEDICAL ETHICS | BMC MED ETHICS | 1472-6939 | 25 | 1 | SSCI;SCIE | ETHICS;MEDICAL ETHICS;SOCIAL SCIENCES, BIOMEDICAL | 2024 | 3.1 | 13.6 | 0 | 2025-05-07 | 0 | 0 | Brain death; Emergency Medicine; Out-of-hospital cardiac arrest; Tissue and organ procurement | POTENTIAL DONORS | Brain death; Emergency Medicine; Out-of-hospital cardiac arrest; Tissue and organ procurement | Adult; Aged; Decision Making; Female; Humans; Life Support Care; Male; Middle Aged; Out-of-Hospital Cardiac Arrest; Registries; Republic of Korea; Retrospective Studies; Tissue and Organ Procurement; Tissue Donors; adult; aged; clinical trial; decision making; donor; epidemiology; ethics; female; human; long term care; male; middle aged; mortality; multicenter study; out of hospital cardiac arrest; register; retrospective study; South Korea; therapy; transplantation | English | 2024 | 2024-09-02 | 10.1186/s12910-024-01090-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Large anomalous Hall conductivity induced by spin chirality fluctuation in an ultraclean frustrated antiferromagnet PdCrO2 | Magnetic frustration, realized in the special geometrical arrangement of localized spins, often promotes topologically nontrivial spin textures in the real space and induces significantly large unconventional Hall responses. This spin Berry curvature effect in itinerant frustrated magnets mainly works with a static spin order, limiting the effective temperature range below the magnetic transition temperature and yielding the typical anomalous Hall conductivity below similar to 10(3) Omega(-1)cm(-1). Here we show that an ultraclean triangular-lattice antiferromagnet PdCrO2 exhibits a large anomalous Hall conductivity up to similar to 10(6) Omega(-1)cm(-1) in the paramagnetic state, which is maintained far above the Neel temperature (T-N) up to similar to 4T(N). The reported enhancement of anomalous Hall response above T-N is attributed to the skew scattering of highly mobile Pd electrons to fluctuating but locally-correlated Cr spins with a finite spin chirality. Our findings point at an alternative route to realizing high-temperature giant anomalous Hall responses, exploiting magnetic frustration in the ultraclean regime. | Jeon, Hoseong; Seo, Hyeongwoo; Seo, Junho; Kim, Yong Hyun; Choi, Eun Sang; Jo, Younjung; Lee, Ho Nyung; Ok, Jong Mok; Kim, Jun Sung | Inst Basic Sci IBS, Ctr Artificial Low Dimens Elect Syst, Pohang 37673, South Korea; Pohang Univ Sci & Technol POSTECH, Dept Phys, Pohang 37673, South Korea; Florida State Univ, Natl High Magnet Field Lab, Tallahassee, FL 32310 USA; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Oak Ridge Natl Lab, Mat Sci & Technol Div, Oak Ridge, TN 37831 USA; Pusan Natl Univ, Dept Phys, Pusan 46241, South Korea | Kim, Yong/R-4856-2018; Kim, Jun Sung/ITV-9063-2023; Lee, Ho/K-2820-2012 | 58985278100; 57914036900; 57192905801; 57211893896; 7402121894; 13502586500; 8860807000; 55744462900; 50061571500 | okjongmok@pusan.ac.kr;js.kim@postech.ac.kr; | COMMUNICATIONS PHYSICS | COMMUN PHYS-UK | 2399-3650 | 7 | 1 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2024 | 5.8 | 13.6 | 0.35 | 2025-05-07 | 3 | 3 | GROWTH | Antiferromagnetic materials; Chirality; Chromium compounds; Temperature; Textures; Antiferromagnets; Hall conductivity; Hall response; Magnetic frustrations; Magnetic transition temperature; Skew scattering; Spin chirality; Spin cluster; Spin textures; Triangular-lattice; Palladium compounds | English | 2024 | 2024-05-21 | 10.1038/s42005-024-01652-3 | 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. © The Royal Society of Chemistry 2025. | Kim, Min Sung; Priyadarsini, Adyasa; Lee, Ju-Hyeon; Bae, Jin-Gyu; Heo, Jeong Yeon; Lee, Hyeon Jeong; Kattel, Shyam; Lee, Ji Hoon | School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, Daegu, 41566, South Korea; Department of Physics, Florida A&M University, Tallahassee, 32307, FL, United States; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, Daegu, 41566, South Korea; Department of Materials Science and Engineering, Ulsan National Institute of Science and Technology, Ulsan, 44919, South Korea; Department of Physics, University of Central Florida, Orlando, 32816, FL, United States; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, Daegu, 41566, South Korea | 58067058900; 57219238604; 57486987100; 57487313300; 58551045300; 56711412600; 36497069200; 55689885200 | 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 | 0.51 | 2025-05-07 | 3 | Carbon capture and storage; Carbon capture and utilization; Kyoto Protocol; Ligands; Nickel; Oxygen reduction reaction; Renewable energy; Zero-carbon; % reductions; Atomic sites; Carbon dioxide reduction; CO 2 emission; Electrochemicals; Environment engineering; Reduction reaction; Single-atoms; Syn gas; ]+ catalyst; Fischer-Tropsch synthesis | English | Final | 2024 | 10.1039/d4ta06720g | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | MOF-derived CeO2 catalysts with Pr doping: engineering oxygen vacancies for improved CO2 conversion to dimethyl carbonate | Producing dimethyl carbonate (DMC) from CO2 and methanol offers significant potential for carbon utilization. Ceria (CeO2) is a key catalyst due to its abundant oxygen vacancies essential for CO2 activation, but enhancing its catalytic performance for practical applications remains challenging. While doping with REMs (rare earth metals) has been recognized as a potential strategy for modulating defect sites of ceria, incorporating praseodymium (Pr) into defect-rich nanostructured ceria to optimize DMC synthesis is still unexplored. Herein, we systematically synthesized a series of CeO2 catalysts using Ce containing metal-organic framework (MOF) templates, including Ce-MOF-808 and Ce-BTC, and further doped them with various rare earth metals (REMs) to evaluate their effectiveness in DMC conversion. Among them, Pr-doped CeO2 derived from Ce-BTC templates exhibited the highest reactivity for DMC formation in a gas-phase flow reaction system. High-resolution imaging (HAADF and ABF-STEM) and spectroscopic analyses (Raman, XANES and XPS) revealed that Pr-doped CeO2 from BTC exhibited significantly higher oxygen defect concentrations. Temperature-programmed desorption (TPD) of CO2 and NH3 showed that Pr-doped CeO2 possesses enhanced acidic and basic properties, attributable to higher oxygen vacancies. These facilitated the formation of key reaction intermediates, such as bicarbonates and methoxy species, observed in in situ DRIFTS, leading to improved DMC yields in gas-phase reactions. Density Functional Theory (DFT) calculations corroborated these experimental findings, highlighting the pivotal role of defect sites in the activation of CO2 and methanol, crucial for efficient DMC formation. | So, Jungseob; Jeong, Min Hye; Yun, Jungwon; An, Byeong-Seon; Kim, Seung-ik; Kim, Geun-yeong; Kim, Hyun-Tak; Chang, Tae Sun; Lee, Jin Hee; Heo, Iljeong; An, Jinjoo; You, Young-Woo; Kim, Minkyu; Kim, Young Jin | Korea Res Inst Chem Technol KRICT, CO2 & Energy Res Ctr, Daejeon 34141, South Korea; Korea Inst Energy Res KIER, Clean Air Res Lab, 152 Gajeong Ro, Daejeon 34129, South Korea; Ohio State Univ, William G Lowrie Chem & Biomol Engn, Columbus, OH 43210 USA; Korea Inst Energy Res KIER, Anal Ctr Energy Res, 152 Gajeong Ro, Daejeon 34129, South Korea; Univ Sci & Technol UST, Adv Mat & Chem Engn Technol, Daejeon 34113, South Korea; Korea Res Inst Chem Technol KRICT, Chem Proc Solut Res Ctr, Daejeon 34141, South Korea; Yeungnam Univ, Sch Chem Engn, 280 Daehak Ro, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | So, Jungseob/LRT-7397-2024; An, ByeongSeon/AAH-4822-2021 | 57192270014; 56486866900; 58150171300; 57191503759; 56528625600; 59404544200; 57190973704; 7404725687; 57217306312; 25928347600; 55847606500; 54390607500; 57116750000; 59054565400 | ywyou@krict.re.kr;mk_kim@ynu.ac.kr;yjkim03@knu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 12 | 46 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 9.5 | 13.6 | 1.01 | 2025-05-07 | 6 | 6 | DEFINED SURFACE PLANES; DEFECT SITES; DOPED CERIA; THIN-FILMS; METHANOL; DIOXIDE; SPECTROSCOPY; METAL; NANOCRYSTALS; PRASEODYMIUM | Atomic emission spectroscopy; Bioremediation; Cerium oxide; Decay (organic); Defect density; Photodissociation; Photoelectron spectroscopy; Photoionization; Photolysis; Praseodymium; Praseodymium compounds; Rate constants; Reaction intermediates; Semiconductor doping; Syngas production; X ray absorption spectroscopy; X ray powder diffraction; Carbon utilization; Carbonate formations; CeO 2; Defect sites; Dimethyl carbonate; Doped CeO; Metalorganic frameworks (MOFs); Rare earth metals; Rare-earth metals; ]+ catalyst; Temperature programmed desorption | English | 2024 | 2024-11-26 | 10.1039/d4ta05554c | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Opportunities and challenges of a dynamic consent-based application: personalized options for personal health data sharing and utilization | BackgroundThe principles of dynamic consent are based on the idea of safeguarding the autonomy of individuals by providing them with personalized options to choose from regarding the sharing and utilization of personal health data. To facilitate the widespread introduction of dynamic consent concepts in practice, individuals must perceive these procedures as useful and easy to use. This study examines the user experience of a dynamic consent-based application, in particular focusing on personalized options, and explores whether this approach may be useful in terms of ensuring the autonomy of data subjects in personal health data usage.MethodsThis study investigated the user experience of MyHealthHub, a dynamic consent-based application, among adults aged 18 years or older living in South Korea. Eight tasks exploring the primary aspects of dynamic consent principles-including providing consent, monitoring consent history, and managing personalized options were provided to participants. Feedback on the experiences of testing MyHealthHub was gathered via multiple-choice and open-ended questionnaire items.ResultsA total of 30 participants provided dynamic consent through the MyHealthHub application. Most participants successfully completed all the provided tasks without assistance and regarded the personalized options favourably. Concerns about the security and reliability of the digital-based consent system were raised, in contrast to positive responses elicited in other aspects, such as perceived usefulness and ease of use.ConclusionsDynamic consent is an ethically advantageous approach for the sharing and utilization of personal health data. Personalized options have the potential to serve as pragmatic safeguards for the autonomy of individuals in the sharing and utilization of personal health data. Incorporating the principles of dynamic consent into real-world scenarios requires remaining issues, such as the need for powerful authentication mechanisms that bolster privacy and security, to be addressed. This would enhance the trustworthiness of dynamic consent-based applications while preserving their ethical advantages. | Lee, Ah Ra; Koo, Dongjun; Kim, Il Kon; Lee, Eunjoo; Yoo, Sooyoung; Lee, Ho-Young | Seoul Natl Univ, Bundang Hosp, Off EHlth Res & Business, 172 Dolma Ro, Seongnam 13605, South Korea; Seoul Natl Univ, Interdisciplinary Program Bioengn, 1 Gwanak Ro, Seoul 08826, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Comp Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Nursing, Res Inst Nursing Sci, 680 Gukchaebosang Ro, Daegu 41944, Daegu, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Nucl Med, 172 Dolma Ro, Seongnam 13605, South Korea | koo, dongjun/HKE-1497-2023 | 57207456585; 57851155100; 14919454400; 56502620400; 57894546600; 56237826800 | debobkr@snubh.org; | BMC MEDICAL ETHICS | BMC MED ETHICS | 1472-6939 | 25 | 1 | SSCI;SCIE | ETHICS;MEDICAL ETHICS;SOCIAL SCIENCES, BIOMEDICAL | 2024 | 3.1 | 13.6 | 0 | 2025-05-07 | 1 | 1 | Dynamic consent; Data sovereignty; Autonomy; Personalized; Personal health data | USER ACCEPTANCE | Autonomy; Data sovereignty; Dynamic consent; Personal health data; Personalized | Adult; Aged; Confidentiality; Female; Health Records, Personal; Humans; Information Dissemination; Informed Consent; Male; Middle Aged; Personal Autonomy; Republic of Korea; Surveys and Questionnaires; Young Adult; adult; aged; article; feedback system; health data; human; male; multiple choice test; open ended questionnaire; pharmacoeconomics; privacy; reliability; security; South Korea; trustworthiness; confidentiality; ethics; female; information dissemination; informed consent; medical record; middle aged; personal autonomy; questionnaire; young adult | English | 2024 | 2024-08-31 | 10.1186/s12910-024-01091-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
