| ○ | ○ | Review | Understanding charge carrier dynamics in organic photocatalysts for hydrogen evolution | Hydrogen generation using particulate photocatalysts is a promising approach to achieving sustainable energy solutions to energy shortages and environmental challenges. Among them, organic semiconductor-based photocatalysts offer significant advantages, including tunable structural and optoelectronic properties, easy of processibility, and cost-effectiveness over the inorganic photocatalysts. However, their photocatalytic efficiency is limited by inherent properties, such as the formation of Frenkel excitons, the presence of numerous energetic defects, and low charge separation efficiency. To enhance performance and expand the potential of organic photocatalysts, it is crucial to understand the relationship between molecular structure and charge carrier dynamics in photocatalytic processes. In this reason, Recent research about organic photocatalysis for hydrogen evolution has focused on uncovering limiting factors and comprehending the fundamental charge carrier behaviors that determine the performance of organic photocatalysts by utilizing the use of advanced time-resolved analysis tools. This review desicribes charge behaviors, including photocharge generation and transport within the bulk of the organic photocatalyst, as well as charge transfer and charge-induced redox reactions at the interface within photocatalytic system. Their characteristics, according to the molecular structures, are summarized based on time-resolved analysis methodologies, including transient spectroscopy with the aim to provide an understanding of the correlation between charge carrier dynamics, molecular structure, and photocatalytic performance. This review surveyed the charge behavior in organic photocatalysis, and elucidated a correlation between molecular structure, charge dynamics and photocatalytic performance. | Choi, Jinhyuk; Jung, Wooteak; Gonzalez-Carrero, Soranyel; Durrant, James R.; Cha, Hyojung; Park, Taiho | Pohang Univ Sci & Technol POSTECH, Dept Chem Engn, 77 Cheongam Ro, Pohang 37673, Gyeongbuk, South Korea; Imperial Coll London, Dept Chem, London W12 0BZ, England; Imperial Coll London, Ctr Processable Elect, London W12 0BZ, England; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | Durrant, James/A-6198-2009; Gonzalez-Carrero, Soranyel/I-2829-2016; Park, Taiho/M-9271-2018 | 58942207700; 57578074400; 56015827500; 56401622800; 35885242200; 8412341200 | hcha@knu.ac.kr;taihopark@postech.ac.kr; | ENERGY & ENVIRONMENTAL SCIENCE | ENERG ENVIRON SCI | 1754-5692 | 1754-5706 | 17 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENERGY & FUELS;ENGINEERING, CHEMICAL;ENVIRONMENTAL SCIENCES | 2024 | 30.8 | 0.4 | 1.33 | 2025-05-07 | 17 | 17 | POLYMER DOTS; CONJUGATED POLYMERS; WATER; EFFICIENT; SEMICONDUCTORS; ENERGY; HETEROJUNCTION; PHOTOREDUCTION; GENERATION; TIO2 | Carrier transport; Cost effectiveness; Dynamics; Hydrogen production; Molecular structure; Photocatalytic activity; Reaction kinetics; Redox reactions; Charge carrier dynamics; Energy shortages; Environmental challenges; Hydrogen generations; Hydrogen-evolution; Organics; Particulates; Performance; Sustainable energy solutions; Time-resolved analysis; catalyst; chemical reaction; hydrogen; molecular analysis; performance assessment; photochemistry; photolysis; Charge transfer | English | 2024 | 2024-10-29 | 10.1039/d4ee01808g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A comparison of novel electrocautery-enhanced lumen-apposing metal stents and plastic stents in endoscopic ultrasound-guided drainage of infected walled-off necrosis: a multicenter randomized study | Background Although lumen-apposing metal stents (LAMSs) have been increasingly used for walled-off necrosis (WON), their advantages over plastic stents in infected WON are unclear. We investigated the safety and efficacy of a novel electrocautery-enhanced LAMS for managing infected WON. Methods Patients who required endoscopic ultrasound-guided WON drainage were randomly assigned to LAMS or plastic stent groups. The primary outcome was total number of direct endoscopic necrosectomy (DEN) procedures required to achieve clinical success. Secondary outcomes included rates of technical success, clinical success, and adverse events. Results 46 patients were included in the LAMS (n = 23) and plastic stent (n = 23) groups. The median total number of DEN procedures did not differ significantly between the plastic stent group (4 procedures, interquartile range [IQR] 2.5-5.0) and LAMS group (9 procedures, IQR 8.0-9.0) ( P = 0.07). The LAMS group demonstrated a significantly higher clinical success rate than the plastic stent group based on intention-to-treat analysis (100% vs. 73.9%, P =0.03) at 8 weeks but not at 4 weeks. Significant bleeding occurred in one patient in the plastic stent group and no patients in the LAMS group. Conclusions We found no significant difference in the total number of DEN procedures between LAMSs and plastic stents for managing infected WON. The only statistically significant finding was a higher clinical success rate at 8 weeks for patients treated with LAMS. The use of LAMS did not result in any adverse events, such as bleeding or buried LAMS syndrome, within the study duration. | Moon, Jong Ho; Park, Se Woo; Lee, Yun Nah; Lee, Sang Hyub; Kim, Seong-Hun; Lee, Dong Wook; Cho, Chang Min; Kim, Sung Bum; Park, Chan Hyuk | SoonChunHyang Univ, Dept Internal Med, Div Gastroenterol, Coll Med, Bucheon, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Dept Internal Med, Div Gastroenterol,Coll Med, 7 Keunjaebong Gil, Hwaseong 18450, Gyeonggi, South Korea; Seoul Natl Univ, Dept Internal Med, Div Gastroenterol, Coll Med, Seoul, South Korea; Jeonbuk Natl Univ, Biomed Res Inst, Dept Internal Med, Jeonbuk Natl Univ Hosp,Res Inst Clin Med, Jeonju, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Gastroenterol, Daegu, South Korea; Yeungnam Univ, Dept Internal Med, Div Gastroenterol, Coll Med, Daegu, South Korea; Hanyang Univ, Guri Hosp, Dept Internal Med, Coll Med, Guri, South Korea | ; Kim, Sung/I-2997-2017; Lee, Yun/J-1260-2014 | 7403231266; 57145012800; 57129189700; 36062488800; 57206878084; 57202974895; 57158287600; 36619660100; 57222484476 | mdsewoopark@gmail.com; | ENDOSCOPY | ENDOSCOPY | 0013-726X | 1438-8812 | 56 | 12 | SCIE | GASTROENTEROLOGY & HEPATOLOGY;SURGERY | 2024 | 12.8 | 0.5 | 3.35 | 2025-05-07 | 6 | 7 | PANCREATIC FLUID COLLECTIONS; TRANSMURAL DRAINAGE; CLINICAL-OUTCOMES; EFFICACY; SAFETY; CLASSIFICATION; NECROSECTOMY; PSEUDOCYST; MANAGEMENT; THERAPY | Adult; Aged; Drainage; Electrocoagulation; Endosonography; Female; Humans; Male; Metals; Middle Aged; Pancreatitis, Acute Necrotizing; Plastics; Stents; Treatment Outcome; Ultrasonography, Interventional; metal; plastic; adult; Article; bacterium culture; cauterization; clinical article; computer assisted tomography; controlled study; endoscopic ultrasonography; endoscopist; false aneurysm; female; human; in-stent restenosis; informed consent; intention to treat analysis; male; middle aged; multicenter study; nuclear magnetic resonance imaging; outcome assessment; pancreas necrosis; percutaneous drainage; prospective study; randomized controlled trial; statistically significant result; walled off necrosis; acute hemorrhagic pancreatitis; adverse event; aged; clinical trial; comparative study; devices; electrocoagulation; interventional ultrasonography; procedures; stent; surgery; therapy; treatment outcome | English | 2024 | 2024-12 | 10.1055/a-2342-1140 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Review | Carbon nitride based nanoarchitectonics for nature-inspired photocatalytic CO2 reduction | Drawing inspiration from the natural process of photosynthesis found in plant leaves, scientists are exploring the use of photocatalysis to convert carbon dioxide (CO2) into valuable products using solar light and water. Photocatalytic CO2 conversion has emerged as one of the efficient green approaches to revitalize the environment from greenhouse gas pollution. Owing to its visible-range band gap, non-toxicity, ease of synthesis at economic costs and stability under light irradiation, g-C3N4 has emerged as the most explored photocatalyst. However, due to rampant exciton recombination owing to poor electrical conductivity, the efficiency of CO2 reduction falls short for g-C3N4 in its pure/pristine form. Therefore, the structural engineering of g-C3N4 materials using N-rich configurations, heteroatom/single-atom doping, and hybridization with various functional materials including metal oxides/sulfides, perovskite halides and metal complexes has been adopted, thereby overcoming their inherent drawbacks in photocatalytic CO2 reduction. In this timely review, we present an overview of the recent advances in surface/interface engineering of carbon nitrides for the conversion of CO2 to fuels and useful chemical by-products. More importance is given to the critical evaluation of surface manipulation in carbon nitrides and how it amplifies and affect their photocatalytic properties in CO2 reduction. Finally, we provide a comprehensive outlook into the future directions of these functionalised carbon nitrides for various applications. We strongly believe that this unique review will offer new knowledge on the surface property relationship of carbon nitride-based materials and their impact on enhancing their performance in photocatalytic CO2 reduction reaction and further create new opportunities for them in various areas. © 2024 The Author(s) | Sadanandan, Aathira M.; Yang, Jae-Hun; Devtade, Vidyasagar; Singh, Gurwinder; Panangattu Dharmarajan, Nithinraj; Fawaz, Mohammed; Mee Lee, Jang; Tavakkoli, Ehsan; Jeon, Chung-Hwan; Kumar, Prashant; Vinu, Ajayan | Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; Material Science & Engineering Department, Kyungpook National University (KNU), 80 Daehakro, Bukgu, Daegu, 41566, South Korea; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; RMIT University, GPO Box 2476, Melbourne, 3001, VIC, Australia; School of Agriculture, Food and Wine, The University of Adelaide, Glen Osmond, SA 5064, Australia; PNU-UON Green Energy Ammonia Global-Hub Research Center, Pusan Clean Energy Research Institute and Pusan CFBC Research Center, Pusan National University, Busan, 46241, South Korea; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia; Global Innovative Centre for Advanced Nanomaterials, The University of Newcastle, NSW-2308, Australia | 57217154838; 57157748500; 58853078100; 57208193925; 58537599400; 57565264000; 58853142600; 36167882900; 7006894320; 57281641400; 6603916006 | JaeHun.Yang@newcastle.edu.au; | Progress in Materials Science | PROG MATER SCI | 0079-6425 | 1873-2208 | 142 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 40 | 0.5 | 8.13 | 2025-05-07 | 75 | Carbon nitride; CO<sub>2</sub> reduction; Doping; Hybridization; Photocatalysis | Artificial photosynthesis; Biomimetics; Carbon dioxide; Energy gap; Greenhouse gases; Metal complexes; Metal halides; Perovskite; Photocatalytic activity; Plants (botany); CO 2 reduction; Gas pollution; Greenhouses gas; Hybridisation; Natural process; Photo-catalytic; Plant leaves; Solar light; Solar waters; Visible range; Carbon nitride | English | Final | 2024 | 10.1016/j.pmatsci.2024.101242 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Defect-enriched BiOIO 3 /Ti3C2 MXene 2D/2D Schottky-type heterostructure for efficient and selective CH 4 production via CO 2 photoreduction: Unveiling the roles of defect inclusion and Ti3 C2 MXene co-catalyst | The photoreduction of CO 2 using solar energy to produce energy-efficient fuels is a sustainable technology that addresses energy needs while reducing carbon emissions. However, synthesizing efficient and robust photocatalysts for this process is challenging. This study introduces a viable approach for highly selective CO 2 photoreduction to CH 4 production by integrating defect-enriched BiOIO 3 (DEBI) with a Ti 3 C 2 (TC) MXene co-catalyst, forming an efficient 2D/2D Schottky-type heterostructure. The DEBI, enhanced with precise defect engineering, showed improved light absorption and charge separation efficiency. In tandem, the TC MXene co-catalyst facilitated rapid electron transfer and significantly minimized charge recombination. Consequently, the DEBI/TC-2 heterostructure, with an optimal 2 wt% TC MXene loading, achieved a CH 4 yield of 52.8 mu mol h -1 g -1 , representing a remarkable 20.5- and 6.3-fold increase over pristine BiOIO 3 and DEBI, respectively. The Schottky-type 2D/2D heterostructure also demonstrated an impressive apparent quantum yield of 0.72%, 99% CH 4 selectivity over H 2 generation, and remarkable stability across multiple cycles. This study underscores the synergistic advantages of defect engineering and MXene co-catalyst integration in a single system, proposing a novel direction for designing highly efficient photocatalysts for solar-driven CO 2 reduction in energy-efficient fuel production.

| ○ | ○ | Article | Fabrication of MXene-derived TiO 2 /Ti 3 C 2 integrated with a ZnS heterostructure and their synergistic effect on the enhanced photocatalytic degradation of tetracycline | Developing innovative photocatalysts for the efficient degradation of pharmaceutical pollutants is crucial in environmental remediation. In this study, we investigate the synthesis of TiO2 nanosheets derived from MXene, specifically integrated onto highly conductive Ti3 C2 MXene, and subsequently combined with zinc sulfide (ZnS) to form a heterojunction. This integration process is accomplished using a hydrothermal approach followed by a self-assembly method. We aim to assess the effectiveness of this integrated system in enhancing the photocatalytic degradation of tetracycline (TC). TiO2 /Ti3 C2 (TT) synthesized in situ exhibits high-energy lattice facets (001) of TiO2 nanosheets, thereby contributing to an exclusive heterojunction within the TiO2 /Ti3 C2 /ZnS (ZTT) heterostructure. The loading of ZnS nanoparticles significantly increases the surface area with a narrow band gap, enhancing the potential for light emission within the visible region. Consequently, ZnS synergistically affects the ZTT x (where x = wt% of ZnS on TT) heterostructure matrix, notably promoting the separation and transfer abilities of the photogenerated carriers. The ZTT5 heterostructure exhibits remarkable adsorption and photoreduction efficiencies, achieving a 97.1 % TC removal in 60 min under UV light. Moreover, under simulated solar light, the ZTT5 heterostructure exhibits an impressive TC removal rate of similar to 93.8 % in 90 min. These results highlight the effective performance of the ZTT5 heterojunction catalyst in facilitating photogenerated charge carriers, leading to improved photocatalytic capabilities. Furthermore, the band structure and density of states of TiO2 (101), Ti3 C2 (002), and ZnS (111) were investigated using density functional theory. In addition, a photoreduction mechanism was proposed for TC, involving the transfer of electrons from TiO2 to the MXene surface. After the transfer, the electrons react with O2 to generate center dot O2 -, attributed to the high electron mobility of MXene. The results of this study emphasize the significant potential of the ZTT5 heterostructure for efficiently degrading pharmaceutical pollutants from wastewater.

| ○ | ○ | Article | Flexural behavior of ribbed CFRP bars in ultra-high-performance fiber-reinforced concrete (UHPFRC) beams with lap-splice connection | Due to transport limitations, lap-splice of CFRP bars is imperative, lap-spliced CFRP bars in ultra-high strength concrete can be an innovative solution by reducing the lap-splice length. This study investigated lap-splice behavior of CFRP bars in UHPFRC and required lap-splice length of CFRP bars by comparing design guidelines. For these purposes, a total of 8 beam specimens were fabricated and subjected to four-point loading. Two beams are control variables, one of which consists of a continuous ribbed CFRP bar, and the other of a mechanical connection by coupler. The main parameters are different lap-splice lengths (20d, 40d, and 60d), and concrete strength (normal strength concrete (NC), high strength concrete (HC), ultra-high-performance fiberreinforced concrete (UHPFRC)), including one beam with traverse reinforcement in the lap-spliced region. Test results showed that the coupler connection was disadvantageous, with the ultimate load reducing by approximately 76 % compared to the un-spliced beam. A lap-splice length of 60d was determined to be the critical length, resulting in 1.0 % and 6.3 % higher ultimate load and developed tensile strength compared to the unspliced beam. The ultimate load was increased by about 14 % due to the contribution of transverse reinforcement in the lap-spliced region. Unlike NC and HC, lap-spliced ribbed CFRP bars in UHPFRC can prevent splitting failure with crack localization around the loading points. Current design guideline for lap-splice length of FRP bars does not predict well ribbed CFRP bars in UHPFRC, and the predicted lap-splice length of ribbed CFRP bars in UHPFRC was shown to be about 42d. | Yoo, Sun-Jae; Yoo, Doo-Yeol; Lee, Jin-Young; Lee, Joo-Ha; Yoon, Young-Soo | Korea Univ, Sch Civil Environm & Architectural Engn, 145 Anam Ro, Seoul 02841, South Korea; Yonsei Univ, Dept Architecture & Architectural Engn, 50 Yonsei Ro, Seoul 03722, South Korea; Kyungpook Natl Univ, Dept Agr Civil Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Suwon, Dept Civil & Environm Engn, 17 Wauan Gil, Hwaseong Si 18323, Gyeonggi Do, South Korea | ; Yoo, Doo-Yeol/AAR-4284-2020 | 57220743534; 57196011623; 57203144661; 23005263800; 7402126768 | leejooha@suwon.ac.kr;ysyoon@korea.ac.kr; | CEMENT & CONCRETE COMPOSITES | CEMENT CONCRETE COMP | 0958-9465 | 1873-393X | 153 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;MATERIALS SCIENCE, COMPOSITES | 2024 | 13.1 | 0.5 | 0.91 | 2025-05-07 | 6 | 5 | Ribbed CFRP bar; UHPFRC; Lap-spliced beam; Bond strength; Minimum lap-splice length | BOND BEHAVIOR; POLYMER BARS; GFRP BARS; STRENGTH; STEEL | Bond strength; Lap-spliced beam; Minimum lap-splice length; Ribbed CFRP bar; UHPFRC | Design; High performance concrete; Reinforced concrete; Bond strength; CFRP bars; High-performance fiber reinforced concretes; Lap splice; Lap splice lengths; Lap-spliced beam; Minimum lap-splice length; Ribbed CFRP bar; Ultra high performance; Ultra-high-performance fiber-reinforced concrete; Tensile strength | English | 2024 | 2024-10 | 10.1016/j.cemconcomp.2024.105700 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Glossed video keyword captions and L2 vocabulary acquisition: an eye-tracking study | The effect of video captions on vocabulary acquisition is a growing topic of interest among L2 researchers. Expanding on this line of inquiry, this study explores how keyword captions enhanced with first language (L1) and second language (L2) glosses (i.e. definitions or brief explanations of unfamiliar words) impact L2 learners’ vocabulary acquisition. This study involved 101 Korean undergraduate students randomly assigned to a baseline (keyword caption only), L1 gloss (keyword caption + L1 gloss), or L2 gloss (keyword caption + L2 gloss) group. The participants viewed a video that corresponded to their group, during which their eye movements were tracked and recorded. Subsequently, the participants completed two vocabulary tests assessing word form and meaning recall. Linear mixed-effects analysis revealed that keyword captions with L1 and L2 glosses resulted in distinct attentional allocation and contributed differently to lexical acquisition. Notably, although the three groups spent similar durations reading the target word forms, the L1 gloss group significantly outperformed the other two groups in word form recall scores. Furthermore, although the L2 gloss group spent three times longer reading L2 glosses compared to the time the L1 gloss group spent reading L1 glosses, the latter had significantly higher scores in the form translation test. These findings have significant implications for L2 pedagogy, particularly regarding the choice between target-language-exclusive or bilingual approaches. © 2024 Informa UK Limited, trading as Taylor & Francis Group. | Lee, Taegang; Choi, Sungmook | Department of English Education, Kyungpook National University, South Korea; Department of English Education, Kyungpook National University, South Korea | 59362619500; 56124260900 | sungmookchoi@knu.ac.kr; | Computer Assisted Language Learning | COMPUT ASSIST LANG L | 0958-8221 | 1744-3210 | SSCI;AHCI | EDUCATION & EDUCATIONAL RESEARCH;LANGUAGE & LINGUISTICS;LINGUISTICS | 2024 | 6.6 | 0.5 | 0 | 2025-05-07 | 0 | Caption; computer assisted language learning; eye-tracking; glossing; vocabulary acquisition | English | Article in press | 2024 | 10.1080/09588221.2024.2412103 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

| ○ | ○ | Article | Perioperative Durvalumab with Neoadjuvant Chemotherapy in Operable Bladder Cancer | BACKGROUND Neoadjuvant chemotherapy followed by radical cystectomy is the standard treatment for cisplatin-eligible patients with muscle-invasive bladder cancer. Adding perioperative immunotherapy may improve outcomes. METHODS In this phase 3, open-label, randomized trial, we assigned, in a 1:1 ratio, cisplatin-eligible patients with muscle-invasive bladder cancer to receive neoadjuvant durvalumab plus gemcitabine-cisplatin every 3 weeks for four cycles, followed by radical cystectomy and adjuvant durvalumab every 4 weeks for eight cycles (durvalumab group), or to receive neoadjuvant gemcitabine-cisplatin followed by radical cystectomy alone (comparison group). Event-free survival was one of two primary end points. Overall survival was the key secondary end point. RESULTS In total, 533 patients were assigned to the durvalumab group and 530 to the comparison group. The estimated event-free survival at 24 months was 67.8% (95% confidence interval [CI], 63.6 to 71.7) in the durvalumab group and 59.8% (95% CI, 55.4 to 64.0) in the comparison group (hazard ratio for progression, recurrence, not undergoing radical cystectomy, or death from any cause, 0.68; 95% CI, 0.56 to 0.82; P<0.001 by stratified log-rank test). The estimated overall survival at 24 months was 82.2% (95% CI, 78.7 to 85.2) in the durvalumab group and 75.2% (95% CI, 71.3 to 78.8) in the comparison group (hazard ratio for death, 0.75; 95% CI, 0.59 to 0.93; P = 0.01 by stratified log-rank test). Treatment-related adverse events of grade 3 or 4 in severity occurred in 40.6% of the patients in the durvalumab group and in 40.9% of those in the comparison group; treatment-related adverse events leading to death occurred in 0.6% in each group. Radical cystectomy was performed in 88.0% of the patients in the durvalumab group and in 83.2% of those in the comparison group. CONCLUSIONS Perioperative durvalumab plus neoadjuvant chemotherapy led to significant improvements in event-free survival and overall survival as compared with neoadjuvant chemotherapy alone. | Powles, Thomas; Catto, James W.

| ○ | ○ | Article | Recrystallization behavior and microstructure evolution of Mg-5Bi-3Al alloy during very high-speed extrusion | In our previous study, we extruded Mg-5Bi-3Al (BA53, wt.%) alloy at a very high speed of 70 m/min, and the high-speed-extruded alloy exhibited an unusual fine grain structure. Since dynamic recrystallization (DRX) behavior determines the microstructure and corresponding mechanical properties of the extruded alloy, understanding its origin is crucial for further improvement and optimization of alloys. Herein, the DRX behavior during high-speed extrusion of the recently developed BA53 alloy was investigated in detail by analyzing the microstructure and texture of the extrusion butt along the extrusion path obtained by water quenching the remaining part of the billet immediately after extrusion. During the initial stages of extrusion with a high extrusion speed of 70 m/min and a high temperature of 400 degrees C, tension twinning predominantly occurred in grains with a high Schmid factor (SF), switching the c -axis of the grains toward the transverse direction of the butt and causing the formation of a ring basal texture. In the intermediate stage, the microstructural changes were dominated by continuous and discontinuous DRX, resulting in the formation of fine recrystallized grains and orientation distribution originated from the parent grain. DRX was completed in the late stage wherein unrecrystallized grains with low SF for basal slip contributed to the late-stage recrystallization, strengthening the ring basal texture. Additionally, DRXed grains with favorable orientation for basal slip underwent lattice rotation, contributing to the formation of the obvious ring basal texture. Finally, preferential grain growth occurred after the DRX, leading to an increase in texture intensity and grain size of the extruded alloy. Therefore, the fine grain structure and ring basal texture obtained through high-speed extrusion were primarily attributed to the activated discontinuous DRX facilitated by a high strain rate and temperature.

| ○ | ○ | Article | Stable switching behavior of low-temperature ZrO2 RRAM devices realized by combustion synthesis-assisted photopatterning | We have realized efficient photopatterning and high-quality ZrO2 films through combustion synthesis and manufactured resistive random access memory (RRAM) devices with excellent switching stability at low temperatures (250 degrees C) using these approaches. Combustion synthesis reduces the energy required for oxide conversion, thus accelerating the decomposition of organic ligands in the UV-exposed area, and promoting the formation of metal-oxygen networks, contributing to patterning. Thermal analysis confirmed a reduction in the conversion temperature of combustion precursors, and the prepared combustion ZrO2 films exhibited a high proportion of metal-oxygen bonding that constitutes the oxide lattice, along with an amorphous phase. Furthermore, the synergistic effect of combustion synthesis and UV/O3 -assisted photochemical activation resulted in patterned ZrO2 films forming even more complete metal-oxygen networks. RRAM devices fabricated with patterned ZrO2 films using combustion synthesis exhibited excellent switching characteristics, including a narrow resistance distribution, endurance of 103 cycles, and retention for 105 s at 85 degrees C, despite low-temperature annealing. Combustion synthesis not only enables the formation of high-quality metal oxide films with low external energy but also facilitates improved photopatterning.

| ○ | ○ | Article | The hippocampal CA2 region discriminates social threat from social safety | The dorsal cornu ammonis 2 (dCA2) region of the hippocampus enables the discrimination of novel from familiar conspecifics. However, the neural bases for more complex social-spatial episodic memories are unknown. Here we report that the spatial and social contents of an aversive social experience require distinct hippocampal regions. While dorsal CA1 (dCA1) pyramidal neurons mediate the memory of an aversive location, dCA2 pyramidal neurons enable the discrimination of threat-associated (CS+) from safety-associated (CS-) conspecifics in both female and male mice. Silencing dCA2 during encoding or recall trials disrupted social fear discrimination memory, resulting in fear responses toward both the CS+ and CS- mice. Calcium imaging revealed that the aversive experience strengthened and stabilized dCA2 representations of both the CS+ and CS- mice, with the incorporation of an abstract representation of social valence into representations of social identity. Thus, dCA2 contributes to both social novelty detection and the adaptive discrimination of threat-associated from safety-associated individuals during an aversive social episodic experience. The hippocampal dorsal CA2 enables the recognition of novel conspecifics. Kassraian et al. show that it is also required for discriminating safety- versus threat-associated conspecifics and that its disruption gives rise to generalized social avoidance. | Kassraian, Pegah; Bigler, Shivani K.; Suarez, Diana M.

| ○ | Article | Boron nitride nanotubes supported icosahedral Pd nanoparticles: Enabling ultrahigh current density-superior hydrogen evolution activity and theoretical insights | An in-situ growth of icosahedral (IC) Pd nanoparticles (NPs) on boron nitride nanotubes (BNNTs) is explored with an external surfactant and reducing agent-free strategy. The IC-Pd@BNNT catalysts show an ultrahigh current density of over − 1000 mA cm−2 with a low overpotential of 199 mV for the hydrogen evolution reaction (HER). At − 20 mA cm−2, the overpotential was as low as 15.7 mV in an acidic medium, which is superior than commercial Pd/C (62.6 mV), and Pt/C (29.4 mV). Moreover, the HER activity of the IC-Pd@BNNT catalysts is maintained even after an accelerated durability test of 40,000 cycles, indicating that the BNNTs are served as a durable support, maintaining the structural integrity of the catalyst. Density functional theory (DFT) calculations confirm that the IC-Pd on the BNNT support with vacancy defects is highly stable and HER active.

| ○ | ○ | Article | Constructing bifunctional and robust covalent organic frameworks via three-component one-pot Doebner reaction for Cr(VI) removal | The integral part of covalent organic frameworks (COFs) is covalent bonds. Thus, stable and functional links must be developed to expand the potential applications of COFs. Herein, in situ linkage functionalization using a threecomponent irreversible Doebner reaction was achieved to fabricate chemically stable carboxylic acid-bearing COFs (Tp-Tta-COOH and Tp-Tapb-COOH), which have abundant chelating groups and ordered electron donor-acceptor moieties facilitating charge separation for effective Cr(VI) adsorption and photoreduction, respectively. These functionalized COFs are more effective at Cr(VI) removal via adsorption and photoreduction than their unfunctionalized counterparts (Tp-Tta and Tp-Tapb). The synergy of adsorption and photocatalysis is crucial to effectively remove Cr(VI) from aqueous solutions. This synergy empowers Tp-Tta-COOH to be used continuously for Cr(VI) removal without any elution after each cycle. Furthermore, Tp-Tta-COOH exhibits high chemical stability, durability, and recyclability. This study will promote the development of durable and useful COF materials for real-world applications. | Hussain, Muzammil; Saddique, Anam; Devarayapalli, Kamakshaiah Charyulu; Kim, Bolam; Cheong, In Woo; Lee, Dae Sung | Kyungpook Natl Univ, Dept Appl Chem, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | 58279975000; 57312386800; 15069351300; 57208922438; 7006733373; 55568524907 | daesung@knu.ac.kr; | APPLIED CATALYSIS B-ENVIRONMENT AND ENERGY | APPL CATAL B-ENVIRON | 0926-3373 | 1873-3883 | 344 | SCIE | CHEMISTRY, PHYSICAL;ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 21.1 | 0.6 | 4.56 | 2025-05-07 | 18 | 18 | Covalent organic framework; Doebner reaction; Linkage functionalization; Cr(VI) removal; Adsorption and photocatalytic reduction; synergy | PHOTOCATALYTIC REDUCTION; DEGRADATION | Adsorption and photocatalytic reduction synergy; Covalent organic framework; Cr(VI) removal; Doebner reaction; Linkage functionalization | Chemical stability; Chromium compounds; Adsorption and photocatalytic reduction synergy; Bi-functional; Covalent organic frameworks; Cr(VI) removal; Doebner reaction; Functionalizations; Linkage functionalization; Photo reduction; Photocatalytic reduction; Three-component; Adsorption | English | 2024 | 2024-05-05 | 10.1016/j.apcatb.2023.123672 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
