| ○ | ○ | Article | Restoration Temperature Control through Glass Transition Temperature Modulation of Shape Memory Polymer for Thermally Switchable Adhesive | Shape memory polymers (SMPs) undergo changes between arbitrary shapes and programmed shapes upon exposure to specific stimulus, allowing them to restore their original shape. All kinds of external stimuli have a threshold to change the shape of the SMP. Especially, for the thermal type SMP, the critical temperature for shape restoration is typically near the glass transition temperature (Tg). In this study, the controllability of the restoration temperature is analyzed by adjusting the Tg of the polymer using Norland Optical Adhesive 63, which can be cured with UV irradiation. By varying the ambient temperature from 20 to 120 degrees C during UV exposure, Tg changes ranging from 35.84 to 50.50 degrees C are obtained, with corresponding changes in restoration temperature. As a practical application, a thermal-activated SMP dry adhesive is developed with programmable Tg and switchable adhesion. The fabricated SMP dry adhesive exhibited strong adhesion to substrates with various surface roughness. Additionally, the shape memory effect allowed for easy detachment through shape recovery, and different adhesive performances at different temperatures are achieved by programming various Tg values. Moreover, the simple manufacturing process of the SMP dry adhesive is confirmed to be suitable for continuous fabrication processes based on roll-to-roll methods. A shape memory polymer dry adhesive with a micro-lens pattern demonstrates adjustable adhesion through the shape memory effect. It adapts to various manufacturing conditions, altering its glass temperature, and adheres effectively to rough surfaces. Continuous fabrication akin to roll-to-roll processing is suggested. image | Park, Han Jun; Kim, Minsu; Lee, Jihoon; Kwak, Moon Kyu | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | ; Kwak, Moon/AGQ-6058-2022 | 57455185400; 57212315616; 59448671600; 57203947984 | mkkwak@knu.ac.kr; | ADVANCED SCIENCE | ADV SCI | 2198-3844 | 11 | 26 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2024 | 14.1 | 7.1 | 5.15 | 2025-05-07 | 12 | 12 | dry adhesive; glass transition temperature; pick-and-place system; shape memory polymer; switchable adhesive | SURFACES; MOLD | dry adhesive; glass transition temperature; pick-and-place system; shape memory polymer; switchable adhesive | Adhesion; Glass; Glass transition; Irradiation; Restoration; Shape optimization; Shape-memory polymer; Surface roughness; Temperature; polymer; Dry adhesive; Glass transition temperature Tg; Pick and place; Pick-and-place system; Restoration temperature; Shape memory polymers; Switchable; Switchable adhesive; Temperature modulation; Thermal; adhesion; article; critical temperature; environmental temperature; glass transition temperature; memory; temperature; ultraviolet irradiation; ultraviolet radiation; Adhesives | English | 2024 | 2024-07 | 10.1002/advs.202309393 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Strengthening Multi-Factor Authentication Through Physically Unclonable Functions in PVDF-HFP-Phase-Dependent a-IGZO Thin-Film Transistors | For enhanced security in hardware-based security devices, it is essential to extract various independent characteristics from a single device to generate multiple keys based on specific values. Additionally, the secure destruction of authentication information is crucial for the integrity of the data. Doped amorphous indium gallium zinc oxide (a-IGZO) thin-film transistors (TFTs) using poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) induce a dipole doping effect through a phase-transition process, creating physically unclonable function (PUF) devices for secure user information protection. The PUF security key, generated at VGS = 20 V in a 20 x 10 grid, demonstrates uniformity of 42% and inter-Hamming distance (inter-HD) of 49.79% in the beta-phase of PVDF-HFP. However, in the gamma-phase, the uniformity drops to 22.5%, and inter-HD decreases to 35.74%, indicating potential security key destruction during the phase transition. To enhance security, a multi-factor authentication (MFA) system is integrated, utilizing five security keys extracted from various TFT parameters. The security keys from turn-on voltage (VON), VGS = 20 V, VGS = 30 V, mobility, and threshold voltage (Vth) exhibit near-ideal uniformities and inter-HDs, with the highest values of 58% and 51.68%, respectively. The dual security system, combining phase transition and MFA, establishes a robust protection mechanism for privacy-sensitive user information. To enhance hardware-based security, extracting multiple keys from a single device based on specific values and ensuring the secure destruction of authentication information is presented. Doped IGZO-based transistors, induced with a dipole doping effect using PVDF-HFP, create PUF devices. The integration of a multi-factor authentication system, utilizing security keys from various device parameters, establishes a robust protection mechanism. image | Han, Youngmin; Lee, Subin; Lee, Eun Kwang; Yoo, Hocheon; Jang, Byung Chul | Gachon Univ, Dept Elect Engn, 1342 Seongnam Daero, Seongnam 13120, South Korea; Pukyong Natl Univ, Dept Chem Engn, Busan 48513, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Bukgu 41566, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Bukgu 41566, Daegu, South Korea | Yoo, Hocheon/ABZ-6637-2022; Lee, EunKwang/NLN-6926-2025; Jang, Byung Chul/GYV-0656-2022 | 58127844600; 57252680900; 55773731500; 56637576900; 9238827900 | hyoo@gachon.ac.kr;bc.jang@knu.ac.kr; | ADVANCED SCIENCE | ADV SCI | 2198-3844 | 11 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2024 | 14.1 | 7.1 | 2.58 | 2025-05-07 | 5 | 7 | crypto-shredding; decryption; encryption; metal oxide; multi-factor authentication; phase transition; physical unclonable function; PVDF-HFP | POLY(VINYLIDENE FLUORIDE) FILMS; CRYSTALLINE PHASES; PERFORMANCE; MORPHOLOGY; INVERSION; MEMBRANE | crypto-shredding; decryption; encryption; metal oxide; multi-factor authentication; phase transition; physical unclonable function; PVDF-HFP | Authentication; Fluorine compounds; Gallium compounds; Hamming distance; II-VI semiconductors; Semiconducting indium compounds; Semiconductor doping; Thin film circuits; Thin film transistors; Thin films; Threshold voltage; Zinc oxide; gallium; indium; metal oxide; polyvinylidene fluoride; zinc oxide; (TFT) using poly(vinylidene fluoride-co-hexafluoropropylene); Amorphous-indium gallium zinc oxides; Crypto-shredding; Decryption; Metal-oxide; Multi-factor authentication; Oxide thinfilm transistors (TFTs); Physically unclonable functions; Poly(vinylidene fluoride-co-hexafluoropropylene); Security key; article; controlled study; dipole; electric potential; encryption; female; human; phase transition; transistor; Cryptography | English | 2024 | 2024-05 | 10.1002/advs.202309221 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | System design of a novel open-air brayton cycle integrating direct air capture | The Direct Air Capture (DAC) technology is essential for achieving carbon neutrality, as it enables processes with net-negative CO2 emissions. However, its widespread commercialization faces significant challenges due to high energy requirements. Numerous attempts have been made to address this issue through thermal integration, yet the fundamental challenge of the high cost associated with extracting large volumes of low-concentration CO2 from ambient air remains unresolved. In this study, the integration of Open-Air Brayton Cycle (OABC) as a solution to enhance overall system utilization by simultaneously utilizing large volumes of ambient air is introduced. Various OABC coupled temperature swing adsorption based DAC system layouts are analyzed while considering different regeneration temperatures, and the results revealed the optimal configurations that significantly reduce energy cost per captured unit of CO2 with high purity and recovery. By combining an equilibrium short-cut model for temperature swing adsorption with process simulation methodologies, this research proposes the concept of "energy cost"-a metric that represents the amount of CO2 captured against the energy penalty incurred by integrating DAC with OABC systems. The findings demonstrate that combining DAC and OABC systems could yield high purity and recovery rates of CO2 through strategic thermal management and advanced adsorbent usage, offering a synergistic approach to carbon capture from an energy consumption perspective. | Son, Seongmin | Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, 80 Daehak ro, Daegu, South Korea | ; Son, Seongmin/KHU-6666-2024 | 56681720100 | seongminson@knu.ac.kr; | CARBON CAPTURE SCIENCE & TECHNOLOGY | CARBON CAPTURE SCI T | 2772-6568 | 13 | ESCI | ENGINEERING, CHEMICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY;ENGINEERING, ENVIRONMENTAL | 2024 | 10.5 | 7.1 | 0.88 | 2025-05-07 | 2 | 2 | Direct air capture; Open-air Brayton cycle; Temperature swing adsorption; Energy analysis; Process simulation | CARBON-DIOXIDE; CO2 ADSORPTION; ADSORBENTS; CAPACITY | Direct air capture; Energy analysis; Open-air Brayton cycle; Process simulation; Temperature swing adsorption | English | 2024 | 2024-12 | 10.1016/j.ccst.2024.100311 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Targeting the Mitochondrial Chaperone TRAP1 Alleviates Vascular Pathologies in Ischemic Retinopathy | Activation of hypoxia-inducible factor 1α (HIF1α) contributes to blood-retinal barrier (BRB) breakdown and pathological neovascularization responsible for vision loss in ischemic retinal diseases. During disease progression, mitochondrial biology is altered to adapt to the ischemic environment created by initial vascular dysfunction, but the mitochondrial adaptive mechanisms, which ultimately contribute to the pathogenesis of ischemic retinopathy, remain incompletely understood. In the present study, it is identified that expression of mitochondrial chaperone tumor necrosis factor receptor-associated protein 1 (TRAP1) is essential for BRB breakdown and pathologic retinal neovascularization in mouse models mimicking ischemic retinopathies. Genetic Trap1 ablation or treatment with small molecule TRAP1 inhibitors, such as mitoquinone (MitoQ) and SB-U015, alleviate retinal pathologies via proteolytic HIF1α degradation, which is mediated by opening of the mitochondrial permeability transition pore and activation of calcium-dependent protease calpain-1. These findings suggest that TRAP1 can be a promising target for the development of new treatments against ischemic retinopathy, such as retinopathy of prematurity and proliferative diabetic retinopathy. © 2023 The Authors.

| ○ | ○ | Article | The Efficacy and Safety of Radiation-Free Retrograde Intrarenal Surgery: A Prospective Multicenter-Based, Randomized, Controlled Trial | Purpose: Fluoroscopy is usually required during retrograde intrarenal surgery (RIRS). Although fluoroscopy is considered necessary for effective and safe RIRS, there is growing awareness regarding radiation exposure risk to patients and surgeons. We conducted a multicenter-based, randomized, controlled trial to compare the safety and effectiveness of radiation-free (RF) RIRS with radiation-usage (RU) RIRS for kidney stone management. Materials and Methods: From August 2020 to April 2022, patients with a unilateral kidney stone (<= 20 mm) eligible for RIRS were prospectively enrolled in 5 tertiary medical centers after randomization and divided into the RF and RU groups. RIRS was performed using a flexible ureteroscope with a holmium:YAG laser. The primary end point of this study was the success rate, defined as complete stone-free or residual fragments with asymptomatic kidney stones <= 3 mm. The secondary end point of this study was ascertaining the safety of RF RIRS. The success rates were analyzed using a noninferiority test. Results: Of the 140 consecutive randomized participants, 128 patients completed this study (RF: 63; RU: 65). The success rates (78% vs 80%, P =.8) were not significantly different between the groups. The rate of highgrade (grade 2-4) ureter injury was not significantly higher in the RF group compared to the RU group (RF = 3 [4.8%] vs RU = 2 [3.1%], P = .6). In RF RIRS, the success rate was noninferior compared to RU RIRS (the difference was 2.2% [95% CI, 0.16-0.12]). Conclusions: This study demonstrated that the surgical outcomes of RF RIRS were noninferior to RU RIRS. | Chung, Jae-Wook; Kang, Jun-Koo; Jung, Wonho; Oh, Kyung Jin; Kim, Hyeon Woo; Shin, Dong Gil; Kim, Bum Soo | Kyungpook Natl Univ, Dept Urol, Sch Med, Daegu, South Korea; Chilgok Kyungpook Natl Univ Hosp, Dept Urol, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Urol, Daegu, South Korea; Keimyung Univ, Sch Med, Dongsan Hosp, Dept Urol, Daegu, South Korea; Chonnam Natl Univ, Med Sch, Dept Urol, Gwangju, South Korea; Pusan Natl Univ, Sch Med, Dept Urol, Busan, South Korea | Kim, Soo-Yeon/ADR-9663-2022 | 35204798500; 57979888100; 56150089500; 12446995700; 56783481000; 36990628800; 57202817150 | urokbs@knu.ac.kr; | JOURNAL OF UROLOGY | J UROLOGY | 0022-5347 | 1527-3792 | 211 | 6 | SCIE | UROLOGY & NEPHROLOGY | 2024 | 6.8 | 7.1 | 3.53 | 2025-05-07 | 7 | 6 | kidney stone; radiation-free; randomized controlled trial | STONE-FREE RATE; FLUOROSCOPY; EXPOSURE; URETEROSCOPY; INSERTION | kidney stone; radiation-free; randomized controlled trial | Adult; Aged; Female; Fluoroscopy; Humans; Kidney; Kidney Calculi; Lasers, Solid-State; Male; Middle Aged; Prospective Studies; Radiation Exposure; Treatment Outcome; Ureteroscopy; anesthetic agent; adult; Article; comparative effectiveness; controlled study; female; human; kidney surgery; major clinical study; male; middle aged; multicenter study; nephrolithiasis; non-inferiority trial; patient safety; prospective study; radiation; radiation free retrograde intrarenal surgery; randomized controlled trial; ureter injury; aged; clinical trial; drug therapy; fluoroscopy; kidney; prevention and control; procedures; radiation exposure; treatment outcome; ureteroscopy | English | 2024 | 2024-06 | 10.1097/ju.0000000000003920 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The photosynthetic uptake of inorganic carbon from Pyropia seaweed aquaculture beds: Scaling up population-level estimations | Seaweed aquaculture beds (SABs) contribute positively to CO2 removal (CDR) worldwide. Among cultivated seaweed species, Pyropia represents approximately 8% of the global seaweed production and has the capacity to sequester a significant amount of carbon from the surface layer of the coastal ocean. In this study, we evaluated the carbon uptake efficiency of Pyropia SABs by measuring their photosynthetic rates. Pyropia individuals were collected from Pyropia SABs on the south and west coasts of South of Korea from December to March (cultivation period) in 2016 to 2019, and the photosynthetic light response curves (P-E curves) were measured. Oxygen-based photosyntheses were converted into carbon-based photosynthetic rates using theoretical photosynthetic quotients. Pyropia thallus consumed an average 37 mg C g- 1ww d-1, with a high ratio of gross primary production to respiration (P/R ratio; 5-14). To quantify the carbon uptake potential in the coastal areas of South Korea during the cultivation period, we extrapolated the carbon uptake rates using the estimated biomass, total area of Pyropia SABs, and meteorological irradiance data. The highest carbon uptake rate (2143 kt C month-1) was observed in the Southwestern Sea of South Korea in December. Considering all productivity data from the entire cultivation period, approximately 6789 kt C was taken up by the Pyropia SABs. Therefore, our study indicates a significant potential to mitigate climate change by reducing greenhouse gas emissions using Pyropia SABs. | Kim, Ju-Hyoung; Moon, Hanbi; Han, Mi-Jung; Jung, Ji Eun; Lee, Na Young; Kang, Jin Woo; Oh, Ji Chul; Park, Geun-Ha; Lee, Seon-Eun; Lee, Myoung Hoon; Park, Chae-Un; Yoon, Ho-Sung; Kim, Haryun | Kunsan Natl Univ, Dept Aquaculture & Aquat Sci, Gunsan 54150, South Korea; Natl Marine Biodivers Inst Korea, Seocheon 33662, South Korea; Chungcheongnamdo Inst Fisheries Resources, Boryung 35508, South Korea; Jeollanamdo Prov Inst Ocean & Fisheries Sci, Goheung Branch, Goheung 59116, South Korea; Fishery Prod Safety Ctr, Fisheries Res Inst, Gunsan 54132, Jeonbuk Do, South Korea; Korea Fisheries Resources Agcy, Fisheries Resources Management Dept, Blue Carbon Implementat Div, Busan 46041, South Korea; Korea Inst Ocean Sci & Technol, Busan 49111, South Korea; Univ Sci & Technol, Daejeon 34113, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Bioresource Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Departmenf Biol, Daegu 41566, South Korea | Kim, Ju-Hyoung/S-6240-2019 | 36446122900; 57217092185; 59204500000; 59204500100; 57344191000; 59850956400; 56906482900; 8107991700; 57208752835; 55850889800; 58781602200; 7402990205; 56181009800 | kharyun@kiost.ac.kr; | AQUACULTURE | AQUACULTURE | 0044-8486 | 1873-5622 | 593 | SCIE | FISHERIES;MARINE & FRESHWATER BIOLOGY | 2024 | 3.9 | 7.1 | 1.29 | 2025-05-07 | 2 | 2 | CO 2 removal; Carbon uptake; Photosynthetic carbon uptake; Pyropia; Seaweed aquaculture beds | RHODOPHYTA; BANGIALES; ACQUISITION; MACROALGAE; MITIGATION; SYSTEM; GROWTH | Carbon uptake; CO<sub>2</sub> removal; Photosynthetic carbon uptake; Pyropia; Seaweed aquaculture beds | carbon sink; climate change; coastal water; inorganic carbon; photosynthesis; red alga; seaweed culture; upscaling | English | 2024 | 2024-12-15 | 10.1016/j.aquaculture.2024.741293 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Tunable Colossal Anomalous Hall Conductivity in Half-Metallic Material Induced by d-Wave-Like Spin-Orbit Gap | The anomalous Hall conductivity (AHC) in magnetic materials, resulting from inverted band topology, has emerged as a key adjustable function in spin-torque devices and advanced magnetic sensors. Among systems with near-half-metallicity and broken time-reversal symmetry, cobalt disulfide (CoS2) has proven to be a material capable of significantly enhancing its AHC. In this study, the AHC of CoS2 is empirically assessed by manipulating the chemical potential through Fe- (hole) and Ni- (electron) doping. The primary mechanism underlying the colossal AHC is identified through the application of density functional theory and tight-binding analyses. The main source of this substantial AHC is traced to four spin-polarized massive Dirac dispersions in the k(z) = 0 plane of the Brillouin zone, located slightly below the Fermi level. In Co0.95Fe0.05S2, the AHC, which is directly proportional to the momentum-space integral of the Berry curvature (BC), reached a record-breaking value of 2507 Omega(-1)cm(-1). This is because the BCs of the four Dirac dispersions all exhibit the same sign, a consequence of the d-wave-like spin-orbit coupling among spin-polarized e(g) orbitals. | Choi, Joonyoung; Park, Jin-Hong; Kyung, Wonshik; Kim, Younsik; Kim, Mi Kyung; Kwon, Junyoung; Kim, Changyoung; Rhim, Jun-Won; Park, Se Young; Jo, Younjung | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Seoul Natl Univ, Res Ctr Novel Epitaxial Quantum Architectures, Dept Phys, Seoul 08826, South Korea; Inst for Basic Sci Korea, Ctr Correlated Electron Syst, Seoul 08826, South Korea; Seoul Natl Univ, Dept Phys & Astron, Seoul 08826, South Korea; Yonsei Univ, Dept Phys, Seoul 03722, South Korea; Pohang Univ Sci & Technol, Dept Phys, Pohang 37673, South Korea; Ajou Univ, Dept Phys, Suwon 16499, South Korea; Soongsil Univ, Dept Phys, Seoul 06978, South Korea; Soongsil Univ, Origin Matter & Evolut Galaxies OMEG Inst, Seoul 06978, South Korea; Soongsil Univ, Integrat Inst Basic Sci, Seoul 06978, South Korea | Park, SeYoung/NOE-4378-2025; Park, Jin-Hong/O-4480-2016; Kim, Changyoung/AAS-4221-2021 | 57199099536; 56095715800; 38461252300; 57218459973; 57199746320; 57913828600; 35264213600; 25625520200; 25957735400; 13502586500 | jwrhim@ajou.ac.kr;sp2829@ssu.ac.kr;jophy@knu.ac.kr; | ADVANCED SCIENCE | ADV SCI | 2198-3844 | 11 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2024 | 14.1 | 7.1 | 0.43 | 2025-05-07 | 0 | 1 | anomalous hall effect; berry curvature; half-metals | STATES | anomalous hall effect; berry curvature; half-metals | Density functional theory; Fruits; Iron compounds; Magnetic materials; Spin polarization; Sulfur compounds; cobalt; disulfide; Anomalous hall effects; Berry curvature; Half metals; Half-metallic materials; Half-metallicity; Hall conductivity; Spin orbits; Spin torque; Spin-polarized; Tunables; article; conductance; controlled study; delta rhythm; density functional theory; dispersion; electron; magnetic sensor; ORBIT score; torque; Cobalt compounds | English | 2024 | 2024-05 | 10.1002/advs.202307288 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Understanding of the Relationship between the Properties of Cu(In,Ga)Se2 Solar Cells and the Structure of Ag Network Electrodes | The relation between the structure of the silver network electrodes and the properties of Cu(In,Ga)Se2 (CIGS) solar cells is systemically investigated. The Ag network electrode is deposited onto an Al:ZnO (AZO) thin film, employing a self-forming cracked template. Precise control over the cracked template's structure is achieved through careful adjustment of temperature and humidity. The Ag network electrodes with different coverage areas and network densities are systemically applied to the CIGS solar cells. It is revealed that predominant fill factor (FF) is influenced by the figure of merit of transparent conducting electrodes, rather than sheet resistance, particularly when the coverage area falls within the range of 1.3-5%. Furthermore, a higher network density corresponds to an enhanced FF when the coverage areas of the Ag networks are similar. When utilizing a thinner AZO film, CIGS solar cells with a surface area of 1.0609 cm2 exhibit a notable performance improvement, with efficiency increasing from 10.48% to 11.63%. This enhancement is primarily attributed to the increase in FF from 45% to 65%. These findings underscore the considerable potential for reducing the thickness of the transparent conductive oxide (TCO) in CIGS modules with implications for practical applications in photovoltaic technology. | Yoo, Hyesun; Quy, Hoang Van; Lee, Inpyo; Jo, Seung Taek; Hong, Tae Ei; Kim, Junho; Yoo, Dae-Hwang; Shin, Jinwook; Commerell, Walter; Kim, Dae-Hwan; Roh, Jong Wook | Kyungpook Natl Univ, Reg Leading Res Ctr RLRC Smart Energy Syst, Daegu 37224, Gyeongsangbug D, South Korea; Daegu Gyeongbuk Inst Sci & Technol DGIST, Div Energy Technol, Daegu 42988, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 47922, South Korea; Incheon Natl Univ, Dept Phys, Nano Photoelect Device Lab, Incheon 22012, South Korea; TH Ulm THU, Prittwitzstr 10, D-89081 Ulm, Germany; Kyungpook Natl Univ, Dept Nano & Adv Mat Sci & Engn, Daegu 37224, Gyeongsangbug D, South Korea | ; HOANG, VAN-QUY/MXL-2792-2025; Yoo, Hyesun/LFU-1949-2024; Kim, JunHo/AAK-8981-2020; Kim, Jihyun/F-6940-2013 | 57211941826; 57204941136; 59177032600; 59177187500; 58638604600; 58743551000; 7103242532; 59178094400; 56431049800; 57778048600; 25638796100 | monolith@dgist.ac.kr;jw.roh@knu.ac.kr; | ENERGY & ENVIRONMENTAL MATERIALS | ENERGY ENVIRON MATER | 2575-0356 | 7 | 6 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 14.1 | 7.1 | 0.69 | 2025-05-07 | 0 | 3 | CIGS; large-area solar cell; metal mesh; metallic network; transparent electrode | CIGS; large-area solar cell; metal mesh; metallic network; transparent electrode | Humidity control; II-VI semiconductors; Silver; Solar cells; Zinc oxide; CIGS; CIGS solar cells; Coverage area; Fill-factor; Large-area solar cells; Metal-mesh; Metallic network; Metallics; Property; Transparent electrode; Transparent electrodes | English | 2024 | 2024-11 | 10.1002/eem2.12765 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | A Novel Structured Si-Based Composite with 2D Structured Graphite for High-Performance Lithium-Ion Batteries | Silicon is a promising alternative to graphite anodes for achieving high-energy-density in lithium-ion batteries (LIBs) because of its high theoretical capacity (3579 mAh g-1). However, silicon anode must be developed to address its disadvantages, such as volume expansion and low electronic conductivity. Therefore, the use of silicon as composed with graphite and carbon anode materials is investigated, which requires properties such as a spherical morphology for high density and encapsulation of silicon particles in the composite. Herein, a graphite@silicon@carbon (Gr@Si@C) micro-sized spherical anode composite is synthesized by mechanofusion process. This composite comprises an outer surface, middle layer, and core pore, which are formed by the capillary force arising from 2D structured graphite and pitch properties. This structure effectively addresses the intrinsic issues associated with Si. Gr@Si@C exhibits a high capacity of 1622 mAh g-1 and capacity retention of 72.2% after 100 cycles, with a high areal capacity 4.2 mAh cm-2. When Gr@Si@C is blended with commercial graphite, the composite exhibits high capacity retention and average Coulombic efficiency after cycling. The Gr@Si@C blended electrode exhibits a high energy density of 820 Wh L-1 with approximate to 16% metallic Si in the electrode (40 wt.% composite), enabling the realization of practical commercial LIBs. Graphite@silicon@carbon (Gr@Si@C) is synthesized by mechanofusion process, consisting of an outer surface, middle layer, and core pore arising from the capillary forces of 2D graphite and pitch properties. It shows good electrochemical performance with high loading level. The blended electrodes employing Gr@Si@C successfully achieve a high energy density, which can be used for the practical implementation of lithium-ion batteries. image | Kim, Min Ji; Lee, Inuk; Lee, Jin Woong; Yoon, Dowoong; Kim, Jung Hyun; Lee, Seungho; Kim, Kwanghyun; Kim, Patrick Joohyun; Choi, Junghyun; Kang, Yun Chan; Jung, Dae Soo | Korea Inst Ceram Engn & Technol, Energy & Environm Div, Jinju 52851, Gyeongnam, South Korea; Korea Univ, Dept Mat Sci & Engn, Seoul 136713, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Gachon Univ, Sch Chem Biol & Battery Engn, Seongnam Si 13120, Gyeonggi Do, South Korea | LEE, JIN/A-5831-2013 | 58366277500; 59335533500; 57704989700; 58073009300; 57369167800; 59627599900; 55261223600; 57195611779; 59883103900; 13612147800; 16233760500 | junghchoi@gachon.ac.kr;yckang@korea.ac.kr;dsjung@kicet.re.kr; | SMALL | SMALL | 1613-6810 | 1613-6829 | 20 | 49 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 12.1 | 7.2 | 0.32 | 2025-05-07 | 3 | 4 | 2D structured graphite; lithium-ion batteries; mechanofusion process; Si-based anode composite | CORE-SHELL STRUCTURE; ANODE MATERIALS; ELECTROCHEMICAL PERFORMANCE; SILICON; CARBON; DESIGN | 2D structured graphite; lithium-ion batteries; mechanofusion process; Si-based anode composite | Carbon electrodes; carbon; graphite; lithium ion; silicon; 2d structured graphite; Graphite anode; Higher energy density; Ion batteries; Lithium ions; Mechanofusion process; Property; Si-based; Si-based anode composite; Silicon carbon; anode electrode; article; capillary; conductance; controlled study; density; electrode; encapsulation; pitch; Anodes | English | 2024 | 2024-12 | 10.1002/smll.202405005 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | An Amiable Design of Cobalt Single Atoms as the Active Sites for Oxygen Evolution Reaction in Desalinated Seawater | Green fuel from water splitting is hardcore for future generations, and the limited source of fresh water (<1%) is a bottleneck. Seawater cannot be used directly as a feedstock in current electrolyzer techniques. Until now single atom catalysts were reported by many synthetic strategies using notorious chemicals and harsh conditions. A cobalt single-atom (CoSA) intruding cobalt oxide ultrasmall nanoparticle (Co3O4 USNP)-intercalated porous carbon (PC) (CoSA-Co3O4@PC) electrocatalyst was synthesized from the waste orange peel as a single feedstock (solvent/template). The extended X-ray absorption fine structure spectroscopy (EXAFS) and theoretical fitting reveal a clear picture of the coordination environment of the CoSA sites (CoSA-Co3O4 and CoSA-N4 in PC). To impede the direct seawater corrosion and chlorine evolution the seawater has been desalinated (Dseawater) with minimal cost and the obtained PC is used as an adsorbent in this process. CoSA-Co3O4@PC shows high oxygen evolution reaction (OER) activity in transitional metal impurity-free (TMIF) 1 M KOH and alkaline Dseawater. CoSA-Co3O4@PC exhibits mass activity that is 15 times higher than the commercial RuO2. Theoretical interpretations suggest that the optimized CoSA sites in Co3O4 USNPs reduce the energy barrier for alkaline water dissociation and simultaneously trigger an excellent OER followed by an adsorbate evolution mechanism (AEM). © 2023 Wiley-VCH GmbH. | Venkateswarlu, Sada; Umer, Muhammad; Son, Younghu; Govindaraju, Saravanan; Chellasamy, Gayathri; Panda, Atanu; Park, Juseong; Umer, Sohaib; Kim, Jeonghyeon; Choi, Sang-Il; Yun, Kyusik; Yoon, Minyoung; Lee, Geunsik; Kim, Myung Jong | Department of Chemistry, Gachon University, Seongnam, 13120, South Korea; Center for Superfunctional Materials, Department of Chemistry, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, South Korea; Department of Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Bionanotechnology, Gachon University, Seongnam, 13120, South Korea; Department of Bionanotechnology, Gachon University, Seongnam, 13120, South Korea; Research Center for Materials Nanoarchitectonics (MANA), National Institute for Material Science, Namiki-1, Tsukuba, 3050044, Japan; Department of Chemistry, Gachon University, Seongnam, 13120, South Korea; Center for Superfunctional Materials, Department of Chemistry, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, South Korea; Department of Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Bionanotechnology, Gachon University, Seongnam, 13120, South Korea; Department of Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Center for Superfunctional Materials, Department of Chemistry, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, South Korea; Department of Chemistry, Gachon University, Seongnam, 13120, South Korea | 55649254900; 57202763136; 57216839175; 57190229119; 57212408423; 57201632042; 58556852900; 57324542300; 57194560892; 56167600800; 35331093900; 25222186500; 58287200800; 55659432400 | myungjongkim@gachon.ac.kr;gslee@unist.ac.kr;myyoon@knu.ac.kr; | Small | SMALL | 1613-6810 | 1613-6829 | 20 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 12.1 | 7.2 | 1.26 | 2025-05-07 | 6 | cobalt single atoms; density functional theory; desalinated seawater; orange peel; oxygen evolution reaction; ultra small Co<sub>3</sub>O<sub>4</sub> | Atoms; Cobalt compounds; Density functional theory; Electrocatalysts; Extended X ray absorption fine structure spectroscopy; Feedstocks; Oxygen; Porous materials; Ruthenium compounds; Seawater; Synthesis (chemical); X ray absorption; X ray absorption near edge structure spectroscopy; Active site; Cobalt single atom; Density-functional-theory; Desalinated seawater; Green fuel; Orange peels; Porous carbons; Single-atoms; Ultra small co3O4; Ultra-small; Potassium hydroxide | English | Final | 2024 | 10.1002/smll.202305289 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Antimicrobial and Antifouling Effects of Petal-Like Nanostructure by Evaporation-Induced Self-Assembly for Personal Protective Equipment | Although the personal protective equipment (PPE) used by healthcare workers (HCWs) effectively blocks hazardous substances and pathogens, it does not fully rule out the possibility of infection, as pathogens surviving on the fabric surface pose a substantial risk of cross-infection through unintended means. Therefore, PPE materials that exhibit effective biocidal activity while minimizing contamination by viscous body fluids (e.g., blood and saliva) and pathogen-laden droplets are highly sought. In this study, petal-like nanostructures (PNSs) are synthesized through the vertical rearrangement of colloidal lamellar bilayers via evaporation-induced self-assembly of octadecylamine, silica-alumina sol, and diverse photosensitizer. The developed method is compatible with various fabrics and imparts visible-light-activated antimicrobial and superhydrophobic-based antifouling activities. PNS-coated fabrics could provide a high level of protection and effectively block pathogen transmission as exemplified by their ability to roll off viscous body fluids reducing bacterial droplet adhesion and to inactivate various microorganisms. The combination of antifouling and photobiocidal activities results in the complete inactivation of sprayed pathogen-laden droplets within 30 min. Thus, this study paves the way for effective contagious disease management and the protection of HCWs in general medical environments, inspiring further research on the fabrication of materials that integrate multiple useful functionalities. Novel coatings based on petal-like nanostructures (PNSs) are prepared by simple dip coating using the evaporation-induced self-assembly of rose bengal, octadecylamine, and silica-alumina sol. PNS-functionalized fabrics demonstrate high protection and disinfection efficiency against hazardous materials such as bacterial droplets and body fluids based on multifunctional superhydrophobic nanostructure-activated antifouling and visible-light-activated photobiocidal properties.image | Lee, Dong Uk; Jeong, Sang Bin; Lee, Byeong Jin; Park, Se Kye; Kim, Hyoung-Mi; Shin, Jae Hak; Lee, Seung Yeon; Kim, Gunwoo; Park, Junghun; Kim, Gyu Man; Jung, Jae Hee; Choi, Dong Yun | Korea Inst Ind Technol, Biomed Mfg Technol Ctr, Yeongcheon 38822, South Korea; Korea Testing Lab, Indoor Environm Ctr, Seoul 08389, South Korea; Sejong Univ, Dept Mech Engn, Seoul 05006, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | ; Lee, Dong Uk/JFK-4156-2023; Choi, Dong Yun/JXO-0495-2024; Kim, Gunwoo/AAL-1188-2021 | 57218710149; 57208903386; 57544771100; 57210575824; 56599741300; 57355464800; 58617701900; 56587225700; 58982918700; 55664733000; 14919395900; 55566743200 | jaehee@sejong.ac.kr;dychoi311@kitech.re.kr; | SMALL | SMALL | 1613-6810 | 1613-6829 | 20 | 14 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 12.1 | 7.2 | 2.52 | 2025-05-07 | 8 | 10 | antifouling; antimicrobial; petal-like nanostructure; self-assembly; superhydrophobic | CORONAVIRUS; EVOLUTION; PRESSURE; SURFACE; AIR | antifouling; antimicrobial; petal-like nanostructure; self-assembly; superhydrophobic | Anti-Infective Agents; Biofouling; Health Personnel; Humans; Infectious Disease Transmission, Patient-to-Professional; Personal Protective Equipment; Alumina; Aluminum oxide; Body fluids; Drops; Evaporation; Hydrophobicity; Nanostructures; Pathogens; Protective coatings; Silica; Sols; antiinfective agent; Anti-foulings; Anti-microbial effects; Antifouling effects; Antimicrobial; Evaporation induced self assemblies; Hazardous substances; Healthcare workers; Personal protective equipment; Petal-like nanostructure; Superhydrophobic; biofouling; health care personnel; human; patient-to-professional transmission; prevention and control; Self assembly | English | 2024 | 2024-04 | 10.1002/smll.202306324 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | Antithrombotic regimen in emergent carotid stenting for acute ischemic stroke due to tandem occlusion: a meta-analysis of aggregate data | BackgroundThe periprocedural antithrombotic regimen might affect the risk-benefit profile of emergent carotid artery stenting (eCAS) in patients with acute ischemic stroke (AIS) due to tandem lesions, especially after intravenous thrombolysis. We conducted a systematic review and meta-analysis to evaluate the safety and efficacy of antithrombotics following eCAS. MethodsWe followed PRISMA guidelines and searched MEDLINE, Embase, and Scopus from January 1, 2004 to November 30, 2022 for studies evaluating eCAS in tandem occlusion. The primary endpoint was 90-day good functional outcome. Secondary outcomes were symptomatic intracerebral hemorrhage, in-stent thrombosis, delayed stent thrombosis, and successful recanalization. Meta-analysis of proportions and meta-analysis of odds ratios were implemented. Results34 studies with 1658 patients were included. We found that the use of no antiplatelets (noAPT), single antiplatelet (SAPT), dual antiplatelets (DAPT), or glycoprotein IIb/IIIa inhibitors (GPI) yielded similar rates of good functional outcomes, with a marginal benefit of GPI over SAPT (OR 1.88, 95% CI 1.05 to 3.35, P-heterogeneity=0.31). Sensitivity analysis and meta-regression excluded a significant impact of intravenous thrombolysis and Alberta Stroke Program Early CT Score (ASPECTS). We observed no increase in symptomatic intracerebral hemorrhage (sICH) with DAPT or GPI compared with noAPT or SAPT. We also found similar rates of delayed stent thrombosis across groups, with acute in-stent thrombosis showing marginal, non-significant benefits from GPI and DAPT over SAPT and noAPT. ConclusionsIn AIS due to tandem occlusion, the periprocedural antithrombotic regimen of eCAS seems to have a marginal effect on good functional outcome. Overall, high intensity antithrombotic therapy may provide a marginal benefit on good functional outcome and carotid stent patency without a significant increase in risk of sICH. | Diana, Francesco; Abdalkader, Mohamad; Behme, Daniel; Li, Wei; Maurer, Christoph Johannes; Pop, Raoul; Hwang, Yang-Ha; Bartolini, Bruno; Da Ros, Valerio; Bracco, Sandra; Cirillo, Luigi; Marnat, Gaultier; Katsanos, Aristeidis H.; Kaesmacher, Johannes; Fischer, Urs; de Sousa, Diana Aguiar; Peschillo, Simone; Zini, Andrea; Tomasello, Alejandro; Ribo, Marc; Nguyen, Thanh N.; Romoli, Michele | Vall dHebron Univ Hosp, Intervent Neuroradiol, Barcelona, Spain; Vall dHebron Res Inst, Stroke Res Grp, Barcelona, Spain; Boston Med Ctr, Radiol, Boston, MA USA; Univ Hosp Magdeburg, Neuroradiol, Magdeburg, Sachsen Anhalt, Germany; Hainan Med Univ, Neurol, Haikou, Hainan, Peoples R China; Univ Hosp Augsburg, Diagnost & Intervent Neuroradiol, Augsburg, Bayern, Germany; Univ Hosp Strasbourg, Intervent Neuroradiol, Strasbourg, France; Kyungpook Natl Univ Hosp, Neurol & Radiol, Daegu, South Korea; CHU Vaudois, Lausanne Univ Hosp, Intervent Neuroradiol Unit, Diagnost & Intervent Radiol, Lausanne, Switzerland; Fdn PTV Policlin Tor Vergata, Biomed & Prevent Diagnost Imaging Unit, Rome, Italy; Azienda Ospedaliera Univ Senese, Intervent Neuroradiol Unit, Neurol & Human Movement Sci, Siena, Italy; Univ Bologna, Biomed & NeuroMotor Sci DIBINEM, Bologna, Italy; Bordeaux Univ Hosp, Intervent & Diagnost Neuroradiol, Bordeaux, France; McMaster Univ, Populat Hlth Res Inst, Neurol Div, Hamilton, ON, Canada; Bern Univ Hosp, Neurol, Inselspital, Bern, Switzerland; Univ Bern, Bern, Switzerland; Univ Lisbon, Hosp Santa Maria, Neurol Serv, Neurosci & Mental Hlth,CHULN, Lisbon, Portugal; Pia Fdn Cardinale G Pan Hosp, Endovascular Neurosurg, Tricase, Italy; UniCamillus Int Med Univ, Rome, Italy; IRCCS Ist Sci Neurolog Bologna, Bologna, Emilia Romagna, Italy; Maggiore Hosp, Neurol & Stroke Ctr, Bologna, Italy; Vall dHebron Univ Hosp, Stroke Unit, Neurol, Barcelona, Spain; Boston Univ, Neurol, Sch Med, Boston, MA USA; Maurizio Bufalini Hosp, Neurol & Stroke Unit, Cesena, Emilia Romagna, Italy | Ribo, Marc/ABG-3202-2021; Fischer, Urs/HJH-5619-2023; Katsanos, Aristeidis/AAD-7458-2019; Behme, Daniel/H-4551-2019; Diana, Francesco/AAZ-9483-2021; Pensato, Umberto/AAT-3058-2020; Maurer, Christoph/AAC-7003-2019; de Sousa, Diana/J-4105-2013; Da Ros, Valerio/AAC-2654-2022; Zini, Andrea/K-1136-2014; MARNAT, Gaultier/J-9908-2019; Aguiar de Sousa, Diana/J-4105-2013; HWANG, Yang-Ha/F-3068-2013; Nguyen, Thanh/ABH-4370-2020; Peschillo, Simone/H-4717-2019; Romoli, Michele/Q-1303-2019; Kaesmacher, Johannes/I-6136-2019; Pop, Raoul/S-9431-2019 | JOURNAL OF NEUROINTERVENTIONAL SURGERY | J NEUROINTERV SURG | 1759-8478 | 1759-8486 | 16 | 3 | SCIE | NEUROIMAGING;SURGERY | 2024 | 4.3 | 7.2 | 17 | stroke; stent; thrombectomy; thrombolysis | MECHANICAL THROMBECTOMY; ENDOVASCULAR TREATMENT; INTRACRANIAL THROMBECTOMY; RETRIEVER THROMBECTOMY; ANTIPLATELET THERAPY; ARTERY; MANAGEMENT; REVASCULARIZATION; THROMBOLYSIS; ALTEPLASE | English | 2024 | 2024-03 | 10.1136/jnis-2023-020204 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Aramid-Reinforced UV Curable Adhesive Resins for Use As an Interlayer in Laminated Glass | Colorless, transparent, and mechanically robust aramid polymers are synthesized from two diamine monomers with strong electron-withdrawing groups, using low-temperature solution condensation with diacid chloride. The aramids dissolved very well in the liquid acrylamide monomers. When N,N-dimethylacrylamide (DMA) is used as a reactive diluent, films with the desired features are produced from the hybrid aramid-DMA resins via ultraviolet (UV) curing. The hybrid films are colorless and transparent in the visible region and showed an increase in the glass transition temperature, tensile strength, and elastic modulus in proportion to the aramid content. Laminated glass is manufactured using the hybrid resin as an interlayer, which exhibits very strong adhesion between the two sheets of glass, is not easily broken by an external impact, and do not scatter fragments. Moreover, the laminated glass do not distort images and functioned very effectively in UV blocking, soundproofing, and suppressing changes in the ambient temperature. Heat treatment further improves the light transmittance and impact resistance of the laminated glass. Laminated glass specimens with various fluorescence colors are also manufactured. Aramid-reinforced films prepared using N,N-diethylacrylamide as a reactive diluent underwent thermally induced phase separation in a wet state, providing smart glass with a privacy protection function. UV-curable adhesive resins reinforced with aramids in a highly dispersed state are developed. Laminated glasses using these as an interlayer shows excellent physical properties such as a high impact resistance, strong adhesion to the glass layers, visible transmission, UV blocking, and noise insulation. Laminated glasses with various fluorescence colors and privacy protection functions are also easily manufactured. image | Lee, Jineun; Lee, Hanna; Kwak, Giseop | Kyungpook Natl Univ, Dept Polymer Sci & Engn, Polymer Nanomat Lab, 1370 Sankyuk Dong, Daegu 702701, South Korea | , Giseop/M-8370-2018 | 57226333374; 59231892900; 17137322300 | gkwak@knu.ac.kr; | SMALL | SMALL | 1613-6810 | 1613-6829 | 20 | 45 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 12.1 | 7.2 | 0.32 | 2025-05-07 | 1 | 2 | adhesive resin; aramid; impact resistance; laminated glass; UV curing | WINDOWS | adhesive resin; aramid; impact resistance; laminated glass; UV curing | Adhesives; Amides; Amines; Chlorine compounds; Curing; Glass; Heat resistance; Laminating; Monomers; Phase separation; Reinforcement; Resins; Temperature; Tensile strength; acrylamide; adhesive agent; aromatic polyamide; carbromal; diamine; diluent; glass; monomer; n,n dimethylacrylamide; polymer; resin; Adhesive resins; Aramid; Dimethyl acrylamide; Laminated glass; Mechanically robust; Reactive diluents; Synthesised; Ultraviolet curable adhesives; Ultraviolet curing; Ultraviolet-curing; adhesion; article; color; controlled study; electron; environmental temperature; fluorescence; glass transition temperature; heat treatment; liquid; low temperature; phase separation; smart glasses; tensile strength; thermotherapy; ultraviolet radiation; Young modulus; Glass transition | English | 2024 | 2024-11 | 10.1002/smll.202404907 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | BEOL-Compatible 4F2 Oscillator Using Vertical InGaAs Biristor for Highly Scalable Monolithic 3D Ising Solver | Ising solvers are important for efficiently addressing non-deterministic polynomial-time (NP)-hard combinatorial optimization problems (COPs), where scalability and compactness are crucial for practical applications. In this study, an experimental demonstration of an oscillator-based Ising solver employing a highly scalable 4F2 InGaAs bi-stable resistor (biristor) is presented. It is first explored the oscillation behavior of the InGaAs biristor, establishing that classical Ising spins can be emulated using the sub-harmonic injection locking (SHIL) technique. Furthermore, capacitive and resistive coupling between two coupled InGaAs biristors is demonstrated, leading to out-of-phase and in-phase coupling, respectively. Employing this foundational technology, it is experimentally achieved a solution to the MaxCUT problem with the InGaAs biristor-based Ising solver, supplemented by simulation-based behavior evaluations. This emerging device architecture offers a viable pathway to surmount the scaling limitations faced by present hardware-based Ising solvers, representing a significant step forward in the development of efficient, scalable solutions for complex optimization challenges. © 2024 The Author(s).
