| ○ | ○ | Article | Adjuvant Chemotherapy and Effect on Long-Term Survival in Ampullary Adenocarcinoma: A Multicenter Cohort Study | BACKGROUND: The role of adjuvant chemotherapy (AC) in patients with ampullary adenocarcinoma (AA) remains controversial. This study aimed to determine if AC could improve the prognosis of patients with resected AA. STUDY DESIGN: This study enrolled patients diagnosed with AA at 9 tertiary teaching hospitals. Patients who did and did not receive AC were matched 1:1 using propensity score. The overall survival (OS) and recurrence-free survival (RFS) were compared between the 2 groups. RESULTS: Of the 1,057 patients with AA, 883 underwent curative-intent pancreaticoduodenectomy, and 255 received AC. Because patients with advanced-stage AA received AC more frequently, the no AC group unexpectedly had a longer OS (not reached vs 78.6 months; p < 0.001) and RFS (not reached vs 18.7 months; p < 0.001) than did the AC group in the unmatched cohort. In the propensity score-matched cohort (n = 296), no difference between the 2 groups in terms of OS (95.9 vs 89.8 months, p = 0.303) and RFS (not reached vs 25.5 months; p = 0.069) was found. By subgroup analysis, patients with advanced stage (pT4 or pN1-2) showed longer OS in the AC group than in the no AC group (not reached vs 15.7 months, p = 0.007: 89.8 vs 24.2 months, p = 0.006, respectively). There was no difference in RFS according to AC in the propensity score-matched cohort. CONCLUSIONS: Given its favorable long-term outcomes, AC can be recommended for patients with resected AA, especially those in the advanced stage (pT4 or pN1-2).

| ○ | ○ | Article | Comparative Risk of Type 2 Diabetes after Gastrectomy and Endoscopic Resection for Gastric Cancer: A Nationwide Cohort Study | BACKGROUND: Patients with gastric cancer (GC) experience 2 characteristic treatment modalities (gastrectomy or endoscopic resection), which may induce heterogeneity in the risk of post-cancer treatment type 2 diabetes (T2D). We investigated differences in the risk for T2D development in survivors of GC according to the 2 treatment methods.STUDY DESIGN: This retrospective nationwide population-based cohort study included 14,646 patients with GC who underwent gastrectomy (n = 12,918) or endoscopic resection (n = 1,728). We enrolled patients who survived for at least 5 years after gastrectomy or endoscopic resection, had no history of diabetes, and had not received adjuvant chemotherapy. T2D risk was evaluated using Cox regression for the gastrectomy group and compared to that of the endoscopic resection group. Because of the competing risks of incident T2D and death, a competing risk regression was performed.RESULTS: After a median follow-up duration of 8.1 years, the incidence rates of T2D in the endoscopic resection group and gastrectomy group were 7.58 and 6.98 per 1,000 person-years, respectively. Patients undergoing gastrectomy showed a significantly higher risk for developing T2D than patients undergoing endoscopic resection (hazard ratio [HR], 1.37; 95% CI 1.18 to 1.58; p < 0.0001). In subgroup analyses, gastrectomy was associated with increased T2D risk in female patients (HR, 1.72; 95% CI 1.22 to 2.43; p = 0.030 for interaction).CONCLUSIONS: Among GC survivors, patients undergoing gastrectomy showed a 37% increased risk of T2D development compared to patients undergoing endoscopic resection. Subgroup analyses showed that T2D risk increased by up to 72% in female patients. These results provide insights for establishing screening and preventive strategies for GC survivors to prevent T2D according to different treatment modalities. (J Am Coll Surg 2023;237:902-910.

| ○ | 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 π-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 μmol h−1 and 0.563 mmol h−1 g−1), compared to the undoped bulk PCN (48.3 μmol 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. © 2024 The Royal Society of Chemistry | Bhoyar, Toshali; Abraham, B.

| ○ | ○ | Article | Dual-purpose tunnel oxide passivated contact on silicon photoelectrodes with high photovoltages for tandem photoelectrochemical devices enabling unassisted water splitting | A tandem photoelectrochemical (PEC) water-splitting device for solar hydrogen production consists of two light absorbers with different bandgaps. Silicon photoelectrodes have been widely investigated as the low bandgap bottom cells of tandem devices because of their bandgap (1.12 eV). Herein, we apply a tunnel oxide passivated contact (TOPCon) on the front and back sides of a Si wafer to prepare a TOPCon Si PEC device. Because TOPCon has a SiO2 tunnel oxide layer providing superior surface passivation and working as a diffusion-blocking layer, TOPCon Si photoelectrodes exhibit superior photovoltage and thermal stability. Both photocathode and photoanode are tested over a broad pH range (0-14) and demonstrate high photovoltages of 640-650 mV under 1 sun illumination and excellent thermal stability by enduring a high processing temperature of up to 600 degrees C for 1 h in air. These advantages of TOPCon Si would provide high efficiency and great design flexibility for monolithic tandem cells. As a preliminary demonstration of the tandem integration, we test two wired tandem PEC devices based on earth-abundant materials, which are a BiVO4 photoanode-TOPCon Si photocathode and halide perovskite photocathode-TOPCon Si photoanode. These devices show STH conversion efficiencies of 0.24 and 3.6%, respectively. | Moon, Choongman; Martinho, Filipe Mesquita Alves; Jung, Gihun; Koh, Jaehyuk; Assar, Alireza; Nam, Sung-Wook; Canulescu, Stela; Shin, Byungha | Korea Adv Inst Sci & Technol KAIST, Dept Mat Sci & Engn, Daejeon 34141, South Korea; Tech Univ Denmark, Dept Photon Engn, DK-4000 Roskilde, Denmark; Tech Univ Denmark, Natl Ctr Nanofabricat & Characterizat, DTU Nanolab, DK-2800 Kongens Lyngby, Denmark; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu 41404, South Korea | Nam, Sung-Wook/V-5519-2019; Canulescu, Stela/E-9096-2010 | 57203192159; 58091560400; 57198355395; 57658586700; 57348894200; 16167127700; 6506921754; 8910734900 | byungha@kaist.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 8 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 0.55 | 2025-06-25 | 10 | 7 | OXYGEN EVOLUTION REACTION; BIVO4 PHOTOANODES; HYDROGEN-PRODUCTION; PROTECTION LAYER; EFFICIENT; TIO2; PERFORMANCE; OXIDATION; SI | Bismuth compounds; Conversion efficiency; Hydrogen production; Passivation; Perovskite; Photocathodes; Photoelectrochemical cells; Silica; Silicon oxides; Silicon wafers; Solar power generation; Thermodynamic stability; Light absorbers; Low bandgap; Photo-anodes; Photo-voltage; Photoelectrochemical devices; Photoelectrochemical water splitting; Photoelectrode; Solar Hydrogen Production; Tunnel oxides; Water splitting; Energy gap | English | 2023 | 2023-02-21 | 10.1039/d2ta07996h | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Energy harvesting of fully-flexible magnetoelectric composites using a piezoelectric P(VDF-TrFE) and magnetostrictive CoFe2O4 nanofiber | In response to the increasing demand for wearable devices, the development of flexible energy harvesters as self-powering systems to replace batteries is accelerating. Flexible magnetoelectric (ME) composites, which can convert practical electrical energy from a magnetic field source, have attracted considerable attention for application in wearable magnetic devices. In this study, a 2-2 type structure based on a flexible magnetostrictive film with cobalt ferrite (CoFe2O4, CFO) nanofibers was adopted to obtain appropriate flexibility and magnetoelectric properties. The flexible ME composite was completely fabricated by coating piezoelectric poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) onto a magnetostrictive film composed of CFO nanofibers and a polyimide matrix. Moreover, we conducted a multiphysics simulation and theoretically proved that a higher strain could be transferred to the piezoelectric layer at higher CFO concentrations, thus resulting in the generation of high magnetoelectric signals from the ME composite. The flexible, robust, and mechanically-stable ME composite reached an output voltage of 0.52 V and a current signal of 25 nA under an external AC magnetic field at 1 Hz. This study led to the development of a fully-flexible design of a bilayer ME composite prepared using a simple fabrication process providing a future avenue for wearable magnetoelectric energy harvesting. | Nam, Chaeyoung; Na, Yujin; Park, Sung Cheol; Kim, Hyunseung; Jeong, Chang Kyu; Hwang, Geon-Tae; Park, Kwi-Il | Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak ro, Daegu 41566, South Korea; Jeonbuk Natl Univ, Div Adv Mat Engn, Jeonju 54896, Jeonbuk, South Korea; Pukyong Natl Univ, Dept Mat Sci & Engn, Pusan 48513, South Korea | ; Kim, Hyungduk/CAH-5630-2022; Jeong, Chang Kyu/ADT-8127-2022; Na, Yujin/LFT-4103-2024; Nam, Pham Cam/KWT-5936-2024; Park, Kwiil/LKN-9445-2024 | gthwang@pknu.ac.kr;kipark@knu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 2 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 28 | NANOGENERATOR; GENERATOR | English | 2023 | 2023-01-03 | 10.1039/d2ta06171f | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | 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 VOC, 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. © 2024 The Royal Society of Chemistry | Kim, Soyoung; Kim, Seon Joong; Ham, Gayoung; Jeong, Ji-Eun; Lee, Donghwa; Lee, Eunho; Ahn, Hyungju; Cha, Hyojung; Shim, Jae Won; Lee, Wonho | Department of Polymer Science and Engineering, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea, Department of Energy Engineering Convergence, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea; School of Electrical Engineering, Korea University, Seoul, 02841, South Korea; Department of Energy Convergence and Climate Change, Kyungpook National University, Daegu, 41566, South Korea; Center for Advanced Specialty Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Department of Chemical Engineering, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea; Department of Chemical Engineering, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea; Pohang Accelerator Laboratory, Gyeongbuk, Pohang, 37673, South Korea; Department of Energy Convergence and Climate Change, Kyungpook National University, Daegu, 41566, South Korea, Department of Hydrogen and Renewable Energy, Kyungpook National University, Daegu, 41566, South Korea; School of Electrical Engineering, Korea University, Seoul, 02841, South Korea; Department of Polymer Science and Engineering, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea, Department of Energy Engineering Convergence, Kumoh National Institute of Technology, Gyeongbuk, Gumi, 39177, South Korea | 55220709200; 58404594700; 58506766600; 56330436800; 59810385700; 57213594810; 56452216500; 35885242200; 7201856264; 57203745111 | jwshim19@korea.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 | 2023 | 10.8 | 9.1 | 0.37 | 2025-06-18 | 4 | Chlorine; Conversion efficiency; Costs; Energy gap; Internet of things; Light sources; Morphology; Blend morphology; Chlorine atom; Indoor light; Organic photovoltaic devices; Organic photovoltaics; Performance; Power conversion efficiencies; Random copolymer; Spectral range; Wide-band-gap; Fullerenes | English | Final | 2023 | 10.1039/d3ta06624j | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Fusion Assessment of Oblique Lumbar Interbody Fusion Using Demineralized Bone Matrix: A 2-Year Prospective Study | Objective: Although several studies have reported successful fusion rates after oblique lum-bar interbody fusion (OLIF) using allografts or dimerized bone matrix (DBM) instead of autografts, whether OLIF can achieve satisfactory solid fusion without the use of autografts remains unclear. This study investigated the real fusion rates after OLIF using allografts and DBM, which were evaluated using both dynamic radiographs and computed tomography scans. Methods: We enrolled 79 consecutive patients who underwent minimally invasive OLIF followed by percutaneous pedicle screw fixation. All patients were treated with OLIF between L2 and L5 and underwent radiographic and clinical follow-ups at 12, 18, and 24 months af-ter surgery. Radiographic assessment of fusion was performed using the modified Brantiga-Steffee-Fraser (mBSF) scale, which was categorized as follows: grades I (radiographic pseu-doarthrosis), II (indeterminate fusion), and III (solid radiographic fusion). Other radio -logic and clinical outcomes were evaluated using the following parameters: vertebral slip-page distance, disc height, subsidence, Oswestry Disability Index (ODI), and visual ana-logue scale (VAS). Results: Clinical outcomes demonstrated significant improvements in the VAS scores for back pain, leg pain, and ODI after surgery. Subsidence was present in 34 cases (35. 4%) at 12 months postoperatively, which increased to 47.9% and reached 50.0% at 1.5 years and 2 years after surgery, respectively. The solid fusion rate after OLIF was 32.3% at 1 year, in-creased to 58.3% at 1.5 years, and reached 72.9% at 2 years. Radiographic pseudoarthrosis was 24.0% at 1 year, which decreased to 6.3% at 1.5 years and 3.1% at 2 years. Conclusion: OLIF is a safe and effective surgical procedure for the treatment of degenera-tive lumbar diseases. The mBSF scale, which simultaneously evaluates both dynamic angles and bone bridge formation, offers great reliability for the radiological assessment of fusion. Moreover, OLIF using allografts and DBM, which is performed on one or 2 levels at L2-5, can achieve satisfactory fusion rates within 2 years after surgery. | Lee, Sangseok; Jung, Jin Woo; Lee, Sang-Woo; Kim, Kyoung-Tae; Kwon, Heum-Dai; Lee, Subum; Ko, Young San; Kim, Pius; Cho, Dae-Chul | Kyungpook Natl Univ Hosp, Dept Neurosurg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Pohang Stroke & Spine Hosp, Dept Neurosurg, Pohang, South Korea; Korea Univ, Coll Med, Anam Hosp, Dept Neurosurg, Seoul, South Korea; Keimyung Univ, Dongsan Hosp, Dept Neurosurg, Coll Med, Daegu, South Korea; Chosun Univ, Coll Med, Dept Neurosurg, Gwangju 61453, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Neurosurg, 130 Dongdeok Ro, Daegu 41944, South Korea; Chosun Univ, Coll Med, Dept Neurosurg, 365 Pilmun Daero, Gwangju 61453, South Korea | ; lee, sangwoo/KUD-1906-2024; Lee, Subum/AFQ-2764-2022 | 58809784100; 57222116456; 57813492500; 57201369790; 57219872171; 57193631061; 57767618800; 57193712475; 55859543400 | gamechanger@chosun.ac.kr;dccho@knu.ac.kr; | NEUROSPINE | NEUROSPINE | 2586-6583 | 2586-6591 | 20 | 4 | SCIE | CLINICAL NEUROLOGY;SURGERY | 2023 | 3.8 | 9.1 | 0.52 | 2025-06-25 | 2 | 2 | Oblique lumbar interbody fusion; Fusion assessment; DBM; modified Branti-ga-Steffee-Fraser scale | SPINE SURGERY; COVID-19; STRATEGY | DBM; Fusion assessment; modified Brantiga-Steffee-Fraser scale; Oblique lumbar interbody fusion | adult; aged; Article; autograft; biomechanics; body mass; bone density; bone matrix; bone metabolism; bone radiography; cervical spine; clinical outcome; cohort analysis; computer assisted tomography; dimerization; dyslipidemia; female; fluoroscopy; follow up; human; hypertension; intervertebral disk degeneration; length of stay; low back pain; lumbar spine; major clinical study; male; nuclear magnetic resonance imaging; oblique lumbar interbody fusion; observational study; operation duration; osteopenia; osteoporosis; Oswestry Disability Index; postoperative care; prospective study; psoas muscle; reliability; sacroiliac joint; Short Form 36; spine fusion; spine surgery; spondylolisthesis; surgical technique; trabecular bone; visual analog scale | English | 2023 | 2023-12 | 10.14245/ns.2347032.516 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Hierarchically engineered unibody Au mesh for stretchable and transparent conductors | Stretchable and transparent conductors (STC) are a critical component of next-generation flexible optoelectronic devices. In this study, novel, junction-free, unibody Au conductors consisting of two-dimensional (2D) web-in-web structures are fabricated to obtain highly conductive STCs. First, a computer fluid dynamics (CFD) simulation is performed to evaluate the stretchability of the potential 2D mesh structures. Conventional photoresist (PR) lithography and electrospinning are then employed to realize the optimized web-in-web network, featuring a hierarchical mesh comprising symmetric large voids and asymmetric small voids. When the large voids in the mesh are aligned diagonally, the mesh can be stretched by up to 70% in stretchability tests without a significant increase in its sheet resistance. The results of the durability tests conducted herein indicate that the mesh structure remains rather stable after 1000 cycles under a constant tensile strain of 40%. In addition, it retains a high transparency of >90% in the visible light range. The use of scalable PR lithography and electrospinning facilitates easy scaling-up of the conductor to the dimensions of wearable devices. Thus, the proposed 2D web-in-web Au conductors and the associated fabrication routes are expected to replace conventional ITO electrodes in the next-generation stretchable optoelectronic devices. | Lee, Hye Min; Kim, Min Ha; Jin, Yusung; Jang, Yunseon; Lee, Pyung Soo; Jeong, Soo-Hwan | Kyungpook Natl Univ, Dept Chem Engn, 80 Daehak Ro, Daegu 41566, South Korea; Chung Ang Univ, Dept Chem Engn & Mat Sci, 84 Heukseok Ro, Seoul 06974, South Korea; SK Hynix R&D Ctr, Kyunggi Do, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 80 Daehak Ro, Daegu 41566, South Korea | Jang, Yunseon/IXW-8517-2023; , SooHwanJeong/JOJ-6732-2023 | 57739404200; 57918560900; 59039800500; 57851212600; 55474663100; 7402425359 | leeps@cau.ac.kr;shjeong@knu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 8 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 0.36 | 2025-06-25 | 5 | 4 | HIGHLY TRANSPARENT; SILVER NANOWIRES; ELECTRODE; NETWORKS; PERCOLATION; GRAPHENE | Durability; Electrospinning; Mesh generation; Optoelectronic devices; Photoresists; Computer fluid dynamic simulations; Critical component; Flexible optoelectronics; Mesh structures; Optoelectronics devices; Photoresist lithography; Stretchable conductors; Transparent conductors; Two-dimensional; Web structures; Tensile strain | English | 2023 | 2023-02-21 | 10.1039/d2ta08971h | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | High thermoelectric and mechanical performance achieved by a hyperconverged electronic structure and low lattice thermal conductivity in GeTe through CuInTe2 alloying | GeTe-based thermoelectric materials have a very high hole carrier concentration (similar to 10(21) cm(-3)), and thus, improving the figure of merit, ZT, is substantially challenging. In this work, we foremost dope Bi to lower the majority carrier concentration, followed by alloying CuInTe2 to further adjust the hole concentration to an optimal level (0.5-2.0 x 10(20) cm(-3)). This strategy also improves the structural symmetry and leads to hyperconverged valence sub-bands and resonance levels, increasing the effective mass from 1.42 m(0) to 1.95 m(0). Consequently, a high power factor of similar to 23 mu W cm(-1) K-2 at room temperature and similar to 41 mu W cm(-1) K-2 at 623 K in the (Ge0.93Bi0.05Te0.98)(CuInTe2)(0.01) sample is reported. Moreover, the introduced point defects and nano-deposits reduce the lattice thermal conductivity to amorphous levels. As a result, the (Ge0.93Bi0.05Te0.98)(CuInTe2)(0.01) sample has a peak ZT value of similar to 2.16 at 623 K and an average ZT value of similar to 1.42 at 300-773 K. A record high hardness value (similar to 277 Hv) is achieved. Simultaneous Bi doping and CuInTe2 alloying appear to be an effective strategy for increasing the ZT values of GeTe-based compounds. | Kim, Hyunji; Kihoi, Samuel Kimani; Shenoy, U.

| ○ | ○ | Article | Laser-induced deposition of Ni, Co-doped FeOOH cocatalysts on WO3 photoanodes and elucidating their roles in water oxidation in terms of carrier dynamics | Oxygen evolution cocatalysts (OECs) are frequently integrated with monoclinic WO3 photoanodes to improve their photoelectrochemical (PEC) water-splitting performance. In this study, we propose laser-induced catalyst deposition (LICD) for the deposition of FeOOH and doped FeOOH OECs on WO3 photoanodes. Furthermore, the roles of OECs in PEC water-splitting are examined in terms of carrier dynamics using ultrafast time-resolved photoluminescence (TRPL) analyses. The highlight of the TRPL study is using shortpass and longpass optical filters to show that the OECs extend the lifetime of holes excited from low-lying states. As a result, it is considered that the OECs provide hole-storing trap states within the bandgap to increase the number of long-lived holes, resulting in improved PEC performance of WO3 photoanodes. | Kim, Hee Yeong; Kong, Heejung; Kim, Jong Hwa; Yang, Won-Geun; Lee, Hyein; Ko, Seonmi; Lee, Hee Jin; Piao, Guangxia; Park, Hyunwoong; Chae, Weon-Sik; Yeo, Junyeob | Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Phys, Novel Appl Nano Opt NANO Lab, Daegu 41566, South Korea; Korea Basic Sci Inst, Daegu Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Instrumental Anal Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Helmholtz Zent Berlin furMaterialien Energie GmbH, Inst Solar Fuels, D-14109 Berlin, Germany | ; Kong, Heejung/CAG-1032-2022; Park, Hyunwoong/A-1247-2012; Yeo, Junyeob/I-1287-2013 | 57777769800; 57552927300; 57208450662; 57191263564; 58110923600; 58110540600; 57214747647; 57193277010; 7601565583; 7003277427; 58692645200 | wschae@kbsi.re.kr;junyeob@knu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 9 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 1.36 | 2025-06-25 | 14 | 15 | HETEROJUNCTION PHOTOANODES; WO3/BIVO4 PHOTOANODES; EFFICIENT; PHOTOELECTRODES; STABILITY; SELECTIVITY; STATE | Cobalt compounds; Deposition; Iron compounds; Lithium compounds; Nickel compounds; Photoelectrochemical cells; Carrier dynamics; Co catalysts; Co-doped; Laser-induced deposition; Monoclinics; Oxygen evolution; Photo-anodes; Photoelectrochemical water splitting; Time-resolved photoluminescence; Water oxidation; Tungsten compounds | English | 2023 | 2023-02-27 | 10.1039/d2ta07004a | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Long-term cycling stability of a SnS2-based covalent organic nanosheet anode for lithium-ion batteries | Various SnS2-based carbonaceous anodes for lithium ion battery (LIB) systems have been developed to enhance the electrochemical performance of SnS2 materials and to overcome the disadvantages of transition metal sulfides with less interfacial surface sites and low electrochemical conductivity. In this study, we introduced a new strategy of hybridization of SnS2 and covalent organic nanosheets (CONs) that have high flexibility, high stability in organic electrolytes, and many interfacial surface sites. The CON provided reaction sites for the growth of SnS2 nanoparticles due to the strong electrostatic interaction between the sulfur heteroatoms of CONs and Sn4+, resulting in the formation of ultrathin SnS2 nanoplates on the CON nanosheets. The resulting SnS2-based CON showed outstanding cyclic stability over 5600 charge/discharge cycles at a current density of 1.0 A g(-1) in the LIB system. In particular, the prominent interfacial surface sites of CONs provided large accessible areas for lithium ions, showing stable successive cycling performances with improved electrical and ionic conductivities. | Jang, Jeong-Hun; Lee, Minseop; Park, Soohyeon; Oh, Jae-Min; Park, Jin Kuen; Paek, Seung-Min | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Hankuk Univ Foreign Studies, Dept Chem, Yongin 17035, Gyeonggi Do, South Korea; Dongguk Univ Seoul, Dept Energy & Mat Engn, Seoul 04620, South Korea | ; Paek, Seung-Min/E-4667-2011; Lee, Minseop/JVZ-7552-2024 | 57198251792; 57201550392; 57432261100; 7402155053; 55085701500; 7102686289 | jaemin.oh@dongguk.edu;jinkpark@hufs.ac.kr;smpaek@knu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 25 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 2.27 | 2025-06-25 | 25 | 26 | NITROGEN-DOPED GRAPHENE; HIGH-PERFORMANCE; SNS2-GRAPHENE NANOCOMPOSITES; SNS2 NANOPARTICLES; IMPEDANCE SPECTRA; NANOTUBES; DECONVOLUTION; TEMPERATURE; FACILE; SHEETS | Anodes; Ions; IV-VI semiconductors; Lithium-ion batteries; Semiconducting tin compounds; Sulfur compounds; Transition metals; Battery systems; Carbonaceous anodes; Cycling stability; Electrochemical performance; Electrochemicals; Hybridisation; Interfacial surface; Organics; Surface sites; Transition metal sulfides; Nanosheets | English | 2023 | 2023-06-27 | 10.1039/d3ta01537h | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Review | Recent advances in MXenes: beyond Ti-only systems | Since the first report on Ti3C2Tx in 2011, the number of reports on 2D transition metal carbides and nitrides, known as MXenes, has increased rapidly. Most of the reports have focused on Ti-based MXenes due to their ease of synthesis and striking properties; however, MXenes beyond Ti-only systems have also been recently reported to exhibit intriguing electronic, magnetic, optical, and mechanical properties. This forward-looking review aims to summarize the research trends, synthesis, properties, and applications of non-Ti MXenes to motivate researchers to unearth the characteristics and unleash the full potential of less explored MXenes. Furthermore, the properties and applications of theoretically predicted non-Ti MXenes are also highlighted to stimulate further research in synthesizing them experimentally. Finally, the challenges to be addressed and future research directions are presented. | Venkateshalu, Sandhya; Shariq, Mohammed; Kim, Byeongyoon; Patel, Monika; Mahabari, Kajal Shakil; Choi, Sang-Il; Chaudhari, Nitin K.; Grace, Andrews Nirmala; Lee, Kwangyeol | Korea Univ, Res Inst Nat Sci, Dept Chem, Seoul 02841, South Korea; Vellore Inst Technol VIT, Ctr Nanotechnol Res, Vellore 632014, Tamil Nadu, India; Pandit Deendayal Energy Univ, Sch Technol, Dept Chem, Gandhinagar 382007, Gujarat, India; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Dept Chem, Daegu 41566, South Korea | Grace, Andrews Nirmala/F-4522-2016; Choi, Sangil/N-7571-2013; Lee, Kwangyeol/A-9269-2010; Kim, Byeongyoon/T-3659-2018; Choi, Sang-Il/N-7571-2013; Chaudhari, Dr. Nitin/C-5428-2016; Venkateshalu, Sandhya/AFX-3591-2022 | 57194620839; 57217054133; 55532693200; 58278732400; 58416510600; 56167600800; 7005987015; 26030388400; 8510322900 | sichoi@knu.ac.kr;nitin.chaudhari@sot.pdpu.ac.in;anirmalagrace@vit.ac.in;kylee1@korea.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 25 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 1.08 | 2025-06-25 | 32 | 31 | 2-DIMENSIONAL MOLYBDENUM CARBIDE; TRANSITION-METAL CARBIDES; SOLID-SOLUTION MXENE; MAX-PHASE COMPOUNDS; ANODE MATERIALS; MAGNETIC-PROPERTIES; V2C MXENE; ELECTROCHEMICAL PROPERTIES; ELECTRONIC-PROPERTIES; OPTICAL-PROPERTIES | Carbides; Forward looking; Future research directions; Optical and mechanical properties; Property; Research applications; Research synthesis; Research trends; Ti-based; Transition metal nitrides; Transition metals carbides; Transition metals | English | 2023 | 2023-06-27 | 10.1039/d3ta01590d | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Self-powered light dimming system using a magneto-mechano-electric generator with hardener-doped Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 single crystals | In this study, Pb(Mg1/3Nb2/3)O-3-Pb(Zr,Ti)O-3 (PMN-PZT) single crystals were doped with hardener Mn at variable concentrations to fabricate a high-output magneto-mechano-electric (MME) generator. The dielectric constant and dielectric loss (tan delta) of the PMN-PZT crystal were gradually decreased by doping with 0 to 0.8 mol% hardener Mn acceptor. Owing to the low energy loss and enhanced energy conversion properties of the Mn-doped hard-type PMN-PZT, the MME generator achieved an improved magnetoelectric coefficient of 783.09 V per cm center dot Oe, and the corresponding mechanical quality factor was 315 at 0.8 mol% Mn under resonance frequency operation conditions. The Mn-modified MME device can generate a root mean square output power of 3.3 mW when an alternating current magnetic field of 8 Oe is applied, which is similar to 1.8 times higher than that of the MME generator fabricated without Mn-doping. Finally, the electric power of the hard-type PMN-PZT MME generator was directly utilized to produce a self-powered light dimming system composed of an MME harvester, an energy conversion circuit, a CdS ambient light sensor, and a light-emitting diode. | Song, Hyunseok; Jang, Jongmoon; Peddigari, Mahesh; Pattipaka, Srinivas; Min, Yuho; Park, Kwi-Il; Jeong, Chang Kyu; Lee, Han Eol; Park, Jung Hwan; Lee, Ho-Yong; Yoon, Woon-Ha; Ryu, Jungho; Hwang, Geon-Tae | Yeungnam Univ, Sch Mat Sci & Engn, Gyongsan 38541, Gyeongsangbug D, South Korea; Korea Inst Mat Sci KIMS, 797 Changwondaero, Chang Won 51508, Gyeongnam, South Korea; Indian Inst Technol Hyderabad, Dept Phys, Kandi 502284, Telangana, India; Pukyong Natl Univ, Dept Mat Sci & Engn, 45 Yongso Ro, Busan 48513, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Jeonbuk Natl Univ, Div Adv Mat Engn, Jeonju, Jeollabuk, South Korea; Kumoh Natl Inst Technol, Dept Mech Engn, Dept Aeronaut Mech & Elect Convergence Engn, 61 Daehak Ro, Gumi 39177, Gyeongbuk, South Korea; Sun Moon Univ, Dept Mat Sci & Engn, Asan 31460, South Korea; Yeungnam Univ, Inst Mat Technol, Gyongsan 38541, Gyeongsangbug D, South Korea | Park, Kwiil/LKN-9445-2024; Song, Hyunseok/LVR-8560-2024; Jeong, Chang Kyu/ADT-8127-2022; Lee, Han/AAS-6899-2020; Pattipaka, Srinivas/P-2993-2019; Ryu, Jungho/LXU-4081-2024 | 57216365707; 55851287300; 56316365700; 57189258366; 36782804100; 35280874200; 55961876600; 56415504500; 55716954000; 7501481650; 15833577200; 57201603501; 36704574900 | jhryu@ynu.ac.kr;gthwang@pknu.ac.kr; | JOURNAL OF MATERIALS CHEMISTRY A | J MATER CHEM A | 2050-7488 | 2050-7496 | 11 | 7 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 10.8 | 9.1 | 1 | 2025-06-25 | 10 | 11 | ENHANCEMENT | Cadmium sulfide; Dielectric losses; Doping (additives); II-VI semiconductors; Single crystals; Synchronous generators; Dimming systems; Enhanced energy conversions; High output; Lower energies; Mn-doped; PMN-PZT; Property; Self-powered; Tan δ; Variable concentration; Magnetos | English | 2023 | 2023-02-14 | 10.1039/d2ta06732c | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
