| ○ | ○ | Article | Latitudinal Variation of the Lifetime Maximum Intensity Location of Atlantic Tropical Cyclones Controlled by the Atlantic Multidecadal Oscillation | The latitude of lifetime maximum intensity (LMI) location (phi(LMI)) of Atlantic tropical cyclones (TCs) is related to the Atlantic Multidecadal Oscillation (AMO) with a significant negative correlation for 1948-2018. We objectively classify TC tracks into four patterns, to evaluate the effects of variations in dominant track patterns (track phi(LMI)) and intra-pattern phi(LMI) (pure phi(LMI)) on the total phi(LMI) variation. During the warm phases of AMO, the prevailed south-origin track patterns and equatorward pure phi(LMI) shifts have almost equally contributed to the equatorward migration of the total phi(LMI). The negative anomaly of potential intensity in the subtropics is responsible for the equatorward shift of pure phi(LMI). Moreover, weak vertical wind shear in the tropics increases the south-origin track patterns. These environmental conditions are associated with the east-strong and west-weak relative sea surface temperature warming during the warm phases that causes anomalous upward and downward motions in the eastern and western Atlantic, respectively. | Kim, Hyeong-Seog; Park, Doo-Sun R.; Ho, Chang-Hoi; Moon, Il-Ju; Chan, Johnny C.

| ○ | ○ | Article | Atomic-scale platinum deposition on photocathodes by multiple redox cycles under illumination for enhanced solar-to-hydrogen energy conversion | The fabrication of photoelectrochemical (PEC) cells using Cu2O, a semiconductor light absorber that responds to infinite sunlight, requires techniques for loading and activating highly efficient cocatalysts to increase the hydrogen production selectivity. However, there has been relatively little interest in techniques for the deposition of efficient catalysts on PEC electrodes that can maximize the surface activation of the light absorption layer for water splitting, because precise control of the Pt loading at the atomic scale is difficult. We designed an intelligent multiple-redox illuminated deposition technique capable of depositing atomic-scale Pt catalysts with optimal performance on the photocathode surface. An Sb:Cu2O/Cu2O/Al:ZnO/TiO2 photocathode with the proposed atomic-scale Pt catalyst has a high photocurrent density of 6.2 mA cm-2 and a more positive onset potential of 0.71 VRHE. In addition, the mass activity of this electrode is 3.35 times higher than that of Pt samples deposited by conventional methods, and the electrode also shows outstanding operational stability. The proposed approach enables a uniform catalyst distribution and position-selective deposition atomic-scale Pt by repeated redox reactions. Consequently, our proposal enables the simultaneous realization of enhanced conversion efficiency and low cost by the consumption of a relatively small quantity of Pt in controllable redox photodeposition. | Choi, Ji Hoon; Kim, Dong Su; Sarker, Swagotom; Lee, Hak Hyeon; Suh, Hee Won; Jung, Sung Hyeon; Lee, Kun Woong; Lee, Ho Seong; Cho, Hyung Koun | Sungkyunkwan Univ, Sch Adv Mat Sci & Engn, 2066 Seobu Ro, Suwon 16419, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea | 김, 동수/IAN-1770-2023; Cho, Hyung Koun/P-2007-2017 | 57218377818; 57209168253; 56067771300; 57923457900; 57222623083; 57200660299; 57255172600; 55706810400; 35236454300 | chohk@skku.edu; | JOURNAL OF POWER SOURCES | J POWER SOURCES | 0378-7753 | 1873-2755 | 533 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 9.2 | 11.7 | 0.53 | 2025-06-25 | 5 | 7 | Photoelectrochemical water splitting; Single -atom catalyst; Redox photoelectrodeposition; Hydrogen evolution reaction | CU2O PHOTOCATHODES; WATER; PERFORMANCE; EFFICIENCY | Hydrogen evolution reaction; Photoelectrochemical water splitting; Redox photoelectrodeposition; Single-atom catalyst | Atomic layer deposition; Atoms; Chemical activation; Copper oxides; Field emission cathodes; Hydrogen production; Light absorption; Photocathodes; Photoelectrochemical cells; Platinum; Redox reactions; Solar power generation; Wide band gap semiconductors; Zinc oxide; Atomic scale; Hydrogen evolution reactions; Photoelectrochemical water splitting; Platinum depositions; Pt catalysts; REDOX cycles; Redox photoelectrodeposition; Single-atom catalyst; Single-atoms; ]+ catalyst; II-VI semiconductors | English | 2022 | 2022-06-15 | 10.1016/j.jpowsour.2022.231410 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nanostructured cobalt-based metal-organic framework/cadmium sulfide electrocatalyst for enhanced oxygen evolution reaction and anion exchange membrane-based water electrolysis: Synergistic effect | Precious metal-free electrocatalysts are essential for green hydrogen using low-cost electrolysis technology for future power supply systems. In this regard, anion-exchange membrane (AEM) electrolysis is the technology of best choice due to its compactness and high efficiency. Here, we proposed a low cost electrocatalyst composed of cadmium sulfide (CdS) nanoparticles decorated in a Cobalt-based metal-organic framework (CdS/ZIF-67), synthesized using a simple coprecipitation method. Compared with pristine Cobalt-based metal-organic framework (ZIF-67), 5 wt%CdS/ZIF-67 has excellent electrochemical oxygen evolution reaction activity, low overpotential (294 mV), low Tafel-slope (100 mV dec(-1)), higher mass activity (25.8 mA mg(-1)), and better stability. The AEM electrolyzer with the 5 wt%CdS/ZIF-67 anode can attain a potential of 1.85 V at a current-density of 1 A cm(-2), which is lower than that of bare Cobalt-based metal-organic framework electrolyzers. Thus, these catalysts are not only very active but also scalable, making them a promising electrolyzer for application in commercial power market. | Devayulalli, Kamakshaiah Charyulu; Lee, Jaewon; Kang, Sinwoo; Moon, Sanghyeon; Vattikuti, S.

| ○ | ○ | Article | Polyanion-assisted ionic-electronic conductive agents designed for high density Si-based anodes | Graphite-silicon (GS) composite electrodes have been actively studied due to the practical aspects as anodes for lithium ion batteries. Unfortunately, the amount of loaded Si in the GS composite electrode is required to be limited to avoid catastrophic issues arising from the volume change of Si anodes. To keep pace with the research trend and enhance the energy density of lithium ion batteries, it is inevitable to increase the density of GS composite electrodes in the cell. However, the permeability of organic electrolyte is typically deteriorated as the electrode gets denser. In addition, some relevant issues associated with the cell resistance and electrode utili-zation seriously aggravate the cell performance. In this study, a capillary-inspired conductive agent (CCA) is employed as an electron/ion dual-conductive agent to address the above-mentioned challenges of high-density GS composite electrodes. Unlike conventional carbon blacks, the CCA is capable of providing an efficient conductive pathway for electrons and improving the electrolyte impregnation property due to the hydrophilic nature of polyanion polymer. Even when a trace amount of CCA (around 2 wt %) is introduced in the electrode composition, high-density GS composite electrodes show significant improvements in capacity retention (85% after 150 cycles) and Coulombic efficiency (99.9%). | Kwon, Jisoo; Kim, Junghwan; Bae, Seong Yeon; Jeon, Seung Pyo; Song, Jin Han; Wang, Sung Eun; Jung, Dae Soo; Jang, Jihyun; Park, Hyunjung; Kim, Patrick Joohyun; Choi, Junghyun | Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Chosun Univ, Dept Mat Sci & Engn, Gwangju 61452, South Korea; Shina T&C Co Ltd, Seoul 08501, South Korea; Seoul Natl Univ, Dept Chem & Biol Engn, Seoul 08826, South Korea | Jang, Jihyun/MGU-1459-2025 | 57356573600; 55966669500; 57752487800; 57752641400; 57752641500; 57221637241; 16233760500; 56031430700; 55713687300; 57195611779; 59883103900 | pjkim@knu.ac.kr;jchoi@kicet.re.kr; | JOURNAL OF POWER SOURCES | J POWER SOURCES | 0378-7753 | 1873-2755 | 541 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 9.2 | 11.7 | 0.75 | 2025-06-25 | 12 | 12 | Conductiveagents; Electrolytepermeability; Lithiumionbattery; Si-basedanode; Electronconductivity; Chargetransfer | ELECTRICAL-CONDUCTIVITY; BATTERY ANODES; PERFORMANCE; NANOPARTICLES; STABILITY; CAPACITY; ENERGY; BINDER; FILM | Charge transfer; Conductive agents; Electrolyte permeability; Electron conductivity; Lithium ion battery; Si-based anode | Anodes; Electrolytes; Graphite electrodes; Ions; Lithium-ion batteries; Silicon; Composites electrodes; Conductive agent; Electrolyte permeability; Electron conductivity; Polyanions; Research trends; Si anodes; Si-based; Si-based anode; Volume change; Charge transfer | English | 2022 | 2022-09-01 | 10.1016/j.jpowsour.2022.231728 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Anti-inflammatory effect of Ailanthus altissima (Mill.) Swingle leaves in lipopolysaccharide-stimulated astrocytes | Ethnopharmacological relevance: Activated astrocytes are involved in the progression of neurodegenerative diseases. Traditionally, Ailanthus altissima (Mill.) Swingle, widely distributed in East Asia, has been used as a medicine for the treatment of fever, gastric diseases, and inflammation. Although A. altissima has been reported to play an anti-inflammatory role in peripheral tissues or cells, its role in the central nervous system (CNS) remains unclear. Aim of the study: In the present study, we investigated the anti-inflammatory effects and mechanism of action of A. altissima in primary astrocytes stimulated by lipopolysaccharide (LPS). Materials and methods: A nitrite assay was used to measure nitric oxide (NO) production, and the tetrazolium salt 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay was performed to determine cyto-toxicity. The expression levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and mitogen-activated protein kinase (MAPK) were determined with western blotting. Reverse-transcription PCR was used to assess the expression of inflammatory cytokines. The levels of reactive oxygen species were measured using 2,7-dichlorodihydrofluorescein diacetate. Luciferase assay and immunocytochemistry were used for assessing nu-clear factor-kappa B (NF-kappa B) transcription and p65 localization, respectively. Memory and social interaction were analyzed using the Y-maze and three-chamber tests, respectively. Results: The ethanol extract of A. altissima leaves (AAE) inhibited iNOS and COX-2 expression in LPS-stimulated astrocytes. Moreover, AAE reduced the transcription of various proinflammatory mediators, hindered NF-kappa B activation, and suppressed extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) acti-vation without p38 activation. Ultra-high performance liquid chromatography with mass spectrometry analysis revealed that AAE comprised ethyl gallate, quercetin, and kaempferol, along with luteolin, which has anti-inflammatory properties, and repressed LPS-induced nitrite levels and the nuclear translocation of p65. Finally, oral administration of AAE attenuated LPS-induced memory and social impairment in mice and repressed LPS-induced ERK and JNK activation in the cortices of mice. Conclusion: AAE could have therapeutic uses in the treatment of neuroinflammatory diseases via suppression of astrocyte activation. | Kim, Sung Rae; Park, Yongun; Li, Mo; Kim, Yeong Kyeong; Lee, Sunmin; Son, Su Young; Lee, Sarah; Lee, Jong Seok; Lee, Choong Hwan; Park, Hyun Ho; Lee, Ji-Yun; Hong, Sungguan; Cho, Young-Chang; Kim, Jung-Woong; Yoo, Hee Min; Cho, Namki; Lee, Hyun-Shik; Lee, Sung Hoon | Chung Ang Univ, 84 Heukseok Ro, Seoul 06974, South Korea; Konkuk Univ, Dept Biosci & Biotechnol, 120 Neungdong Ro, Seoul 05029, South Korea; Natl Inst Biol Resources, Environm Res Complex, 42 Hwangyeong Ro, Incheon 22755, South Korea; Chung Ang Univ, Dept Chem, 84 Heukseok Ro, Seoul 06974, South Korea; Chonnam Natl Univ, Coll Pharm, 77 Yongbong Ro, Gwangju 61186, South Korea; Chung Ang Univ, Dept Life Sci, Seoul 06974, South Korea; Korea Res Inst Stand & Sci, Ctr Bioanal, Daejeon 34113, South Korea; Chonnam Natl Univ, Coll Pharm, Res Inst Pharmaceut Sci, Gwangju 61186, South Korea; Kyungpook Natl Univ, Coll Nat Sci, KNU Ctr Nonlinear Dynam, Sch Life Sci,CMRI,BK21 Four KNU Creat BioRes Grp, Daegu 41566, South Korea | hong, sungguan/HNB-3658-2023; Kim, Kyu/E-7814-2012; Yoo, Hee/AAF-6230-2021; Kim, So-Young/JFS-7698-2023; Yeon-Ju, Lee/G-4317-2013; Kim, Jung-Woong/LKJ-2288-2024; park, hyun/D-2627-2011; choi, sun ryoung/AGZ-1893-2022 | 55658386600; 57226119906; 57226107428; 57226099907; 57203597258; 55586717400; 55486567500; 8098096200; 8934856300; 7601569577; 37124481700; 37045455800; 55472205600; 57217845772; 57226094801; 54883160400; 16316010200; 56044368400 | sunghoonlee@cau.ac.kr; | JOURNAL OF ETHNOPHARMACOLOGY | J ETHNOPHARMACOL | 0378-8741 | 1872-7573 | 286 | SCIE | CHEMISTRY, MEDICINAL;INTEGRATIVE & COMPLEMENTARY MEDICINE;PHARMACOLOGY & PHARMACY;PLANT SCIENCES | 2022 | 5.4 | 11.9 | 1.78 | 2025-06-25 | 17 | 17 | Ailanthus altissima; astrocytes; Nuclear factor kappa-light-chain-enhancer of; activated B cells Pathway; MAPK; Neuroinflammation; Behaviors | NF-KAPPA-B; NITRIC-OXIDE SYNTHASE; INDUCED NEUROINFLAMMATION; SYNAPTIC PLASTICITY; SIGNALING PATHWAYS; EXPRESSION; MAPK; INFLAMMATION; P38; ACTIVATION | Ailanthus altissima, astrocytes; Behaviors; MAPK; Neuroinflammation; Nuclear factor kappa-light-chain-enhancer of activated B cells Pathway | Ailanthus; Animals; Anti-Inflammatory Agents; Astrocytes; Cytokines; Inflammation; Lipopolysaccharides; Male; Mice; Mice, Inbred C57BL; Neuroinflammatory Diseases; Nitric Oxide; Plant Extracts; Plant Leaves; Ailanthus altissima extract; antiinflammatory agent; cyclooxygenase 2; gallic acid; immunoglobulin enhancer binding protein; inducible nitric oxide synthase; kaempferol; lipopolysaccharide; luteolin; mitogen activated protein kinase; nitric oxide; nitrite; plant extract; quercetin; quinic acid; reactive oxygen metabolite; stress activated protein kinase; synaptotagmin I; tetrazolium; tiletamine plus zolazepam; unclassified drug; xylazine; antiinflammatory agent; cytokine; nitric oxide; plant extract; animal cell; animal experiment; antiinflammatory activity; Article; astrocyte; brain cortex; cell stimulation; controlled study; drug cytotoxicity; enzyme activation; enzyme inhibition; gene expression; immunocytochemistry; luciferase assay; male; mass spectrometry; maze test; memory; mouse; MTT assay; nonhuman; plant leaf; protein expression level; protein localization; rat; reverse transcription polymerase chain reaction; social interaction; ultra performance liquid chromatography; Western blotting; Ailanthus; animal; astrocyte; C57BL mouse; chemistry; drug effect; inflammation; isolation and purification; metabolism; pathology; plant leaf | English | 2022 | 2022-03-25 | 10.1016/j.jep.2021.114258 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Anti-neuroinflammatory activity of 6,7-dihydroxy-2,4-dimethoxy phenanthrene isolated from Dioscorea batatas Decne partly through suppressing the p38 MAPK/NF-κB pathway in BV2 microglial cells | Ethnopharmacological relevance: The rhizome of Dioscorea batatas Decne (called Chinses yam) widely distributed in East Asian countries including China, Japan, Korea and Taiwan has long been used in oriental folk medicine owing to its tonic, antitussive, expectorant and anti-ulcerative effects. It has been reported to have anti-inflammatory, antioxidative, cholesterol-lowering, anticholinesterase, growth hormone-releasing, antifungal and immune cell-stimulating activities. Aim of the study: Neuroinflammation caused by activated microglia contributes to neuronal dysfunction and neurodegeneration. In the present study, the anti-neuroinflammatory activity of 6,7-dihydroxy-2,4-dimethoxy phenanthrene (DHDMP), a phenanthrene compound isolated from Dioscorea batatas Decne, was examined in microglial and neuronal cells. Materials and methods: A natural phenanthrene compound, DHDMP, was isolated from the peel of Dioscorea batatas Decne. The anti-neuroinflammatory capability of the compound was examined using the co-culture system of BV2 murine microglial and HT22 murine neuronal cell lines. The expression levels of inflammatory mediators and cytoprotective proteins in the cells were quantified by enzyme-linked immunosorbent assay and Western blot analysis. Results: DHDMP at the concentrations of ≤1 μg/mL did not exhibit a cytotoxic effect for BV2 and HT22 cells. Rather DHDMP effectively restored the growth rate of HT22 cells, which was reduced by co-culture with lipopolysaccharide (LPS)-treated BV2 cells. DHDMP significantly decreased the production of proinflammatory mediators, such as nitric oxide, tumor necrosis factor-α, interleukin-6, inducible nitric oxide synthase, and cyclooxygenase-2 in BV2 cells. Moreover, DHDMP strongly inhibited the nuclear translocation of nuclear factor κB (NF-κB) and phosphorylation of p38 mitogen-activated protein kinase (MAPK) in BV2 cells. The compound did not affect the levels and phosphorylation of ERK and JNK. Concurrently, DHDMP increased the expression of heme oxygenase-1 (HO-1), an inducible cytoprotective enzyme, in HT22 cells. Conclusions: Our findings indicate that DHDMP effectively dampened LPS-mediated inflammatory responses in BV2 microglial cells by suppressing transcriptional activity of NF-κB and its downstream mediators and contributed to HT22 neuronal cell survival.

| ○ | ○ | Article | Distinct volumetric features of cerebrospinal fluid distribution in idiopathic normal-pressure hydrocephalus and Alzheimer's disease | Objective The aims of the study were to measure the cerebrospinal fluid (CSF) volumes in the lateral ventricle, high-convexity subarachnoid space, and Sylvian fissure region in patients with idiopathic normal-pressure hydrocephalus (INPH) and Alzheimer's disease (AD), and to evaluate differences in these volumes between INPH and AD groups and healthy controls. Methods Forty-nine INPH patients, 59 AD patients, and 26 healthy controls were imaged with automated three-dimensional volumetric MRI. Results INPH patients had larger lateral ventricles and CSF spaces of the Sylvian fissure region and smaller high-convexity subarachnoid spaces than other groups, and AD patients had larger lateral ventricles and CSF spaces of the Sylvian fissure region than the control group. The INPH group showed a negative correlation between lateral ventricle and high-convexity subarachnoid space volumes, while the AD group showed a positive correlation between lateral ventricle volume and volume for CSF spaces of the Sylvian fissure region. The ratio of lateral ventricle to high-convexity subarachnoid space volumes yielded an area under the curve of 0.990, differentiating INPH from AD. Conclusions Associations between CSF volumes suggest that there might be different mechanisms between INPH and AD to explain their respective lateral ventricular dilations. The ratio of lateral ventricle to high-convexity subarachnoid space volumes distinguishes INPH from AD with good diagnostic sensitivity and specificity. We propose to refer to this ratio as the VOSS (ventricle over subarachnoid space) index. | Han, Jaehwan; Kim, Myoung Nam; Lee, Ho-Won; Jeong, Shin Young; Lee, Sang-Woo; Yoon, Uicheul; Kang, Kyunghun | Kyungpook Natl Univ, Sch Med, Dept Biomed Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu, South Korea; Daegu Catholic Univ, Dept Biomed Engn, 13-13 Hayang Ro, Gyongsan 38430, Gyeongbuk, South Korea | Yoon, Uicheul/AFG-0112-2022; lee, sangwoo/KUD-1906-2024; Kim, Sunghoon/Z-2981-2019 | 57211638640; 57212315655; 35337240700; 36164032500; 57196249819; 7003570756; 55365592200 | yoonuc@cu.ac.kr;Kyunghun.Kang@hotmail.com; | FLUIDS AND BARRIERS OF THE CNS | FLUIDS BARRIERS CNS | 2045-8118 | 19 | 1 | SCIE | NEUROSCIENCES | 2022 | 7.3 | 11.9 | 0.7 | 2025-06-25 | 7 | 8 | Idiopathic normal-pressure hydrocephalus; Cerebrospinal fluid space; Magnetic resonance imaging; Alzheimer's disease | BRAIN-REGIONS; MR; DIAGNOSIS; PROGRESSION; DEMENTIA | Alzheimer’s disease; Cerebrospinal fluid space; Idiopathic normal-pressure hydrocephalus; Magnetic resonance imaging | English | 2022 | 2022-09-01 | 10.1186/s12987-022-00362-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | In-situ measurement of drying and electrochemical-cycling-induced mechanical behavior and delamination of polypyrrole electrodes for energy storage applications | Delamination during the fabrication and operation of thick electrodes is one of the major instabilities that prevent their utility for high energy density electrochemical devices. In this study, we investigate the defor-mation and delamination of polypyrrole (pPy) film electrodes using in-situ measurements of curvature/stress. At the beginning of drying process, the water in the film exited continuously, while the film did not deform accordingly. Then, the film rapidly contracted near the end of the evaporation process and remained in its equilibrium contracted state. The film deformation was found to be caused by the evaporation of moisture near the polymer chain, whereas it was not affected by the evaporation of free water in the pores, causing the mismatch between the deformation and evaporation. Importantly, film delamination was identified in real time as the rapid stress drop corresponded to the peeling of the film from the substrate. The interfacial fracture energy was quantified to estimate the adhesion strength of the interface with various treatments. Moreover, electrochemical-cycling-induced delamination was successfully identified based on the type of delamination. We believe this study would be beneficial for both the development and operation of thick electrodes with high energy density and stability. | Kim, Kyung-Geun; Park, Gyeong Hun; Agumba, Dickens O.; Kim, Sung Yeol | Kyungpook Natl Univ, Sch Mech Engn, Daegu 702701, South Korea; Inha Univ, Creat Res Ctr Nanocellulose Future Composites, Dept Mech Engn, Inha Ro 100, Incheon 22212, South Korea; Kyungpook Natl Univ, Sch Convergence, Dept Hydrogen & Renewable energy, Daegu 702701, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Sch Convergence, Dept Hydrogen & Renewable energy, Daegu 702701, South Korea | ; Kim, Sung Yeol/D-1412-2013; Kim, Kipoong/IFT-8155-2023; kim, sung/D-1412-2013 | 56991540300; 57882315900; 57219610441; 19337822900 | sykim.knu@gmail.com; | SURFACES AND INTERFACES | SURF INTERFACES | 2468-0230 | 34 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 6.2 | 11.9 | 0.32 | 2025-06-25 | 4 | 4 | Stability; Delamination; Polypyrrole; Mechanical behavior; Adhesion; Fracture energy | BENDING BEAM METHOD; STRESS DEVELOPMENT; ION; FILMS; BATTERIES; TRANSPORT; POLYMERS; WATER; PPY | Adhesion; Delamination; Fracture energy; Mechanical behavior; Polypyrrole; Stability | English | 2022 | 2022-11 | 10.1016/j.surfin.2022.102297 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Non-volatile flash memory based on Van der Waals gate stack using bandgap tunability of hexagonal boron nitride | Electronic devices based on two-dimensional (2D) materials have extended their applications to non-volatile flash memory devices. The gate stack is a key structure in flash memory devices, and the conventional siliconoxide-nitride-oxide-silicon (SONOS) structure has been widely applied. In this study, we propose a van der Waals (vdW) gate stack based on graphene, molybdenum disulfide (MoS2), and hexagonal boron nitride (hBN) for next-generation flash memory devices. Owing to the bandgap tunability of hBN by functionalization, hBN is capable of forming a tunneling layer, charge trap layer, and blocking layer with different bandgaps, resulting in a suitable energy band offset for program/erase operations and charge storage. This study on the vdW gate stack of MoS2/tunneling hBN/charge trap hBN/blocking hBN/graphene was carried out through technology computeraided design (TCAD) simulation. The trapped charge density and threshold voltage (Vth) shift were investigated for different bandgaps of the hBN layers. Moreover, the pulse width and cycle were varied to reveal the charge-trapping behavior for further applications. | Jang, Byung Chul; Park, Hamin | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Kwangwoon Univ, Dept Elect Engn, 20 Gwangun Ro, Seoul 01897, South Korea | Jang, Byung Chul/GYV-0656-2022 | 9238827900; 57188966274 | parkhamin@kw.ac.kr; | SURFACES AND INTERFACES | SURF INTERFACES | 2468-0230 | 32 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 6.2 | 11.9 | 0.16 | 2025-06-25 | 2 | 2 | Flash memory; Van der Waals heterostructure; Energy bandgap; Energy band offset; Interface engineering; Hexagonal boron nitride | MOS2 TRANSISTORS; GRAPHENE; GAP | Energy band offset; Energy bandgap; Flash memory; Hexagonal boron nitride; Interface engineering; Van der Waals heterostructure | English | 2022 | 2022-08 | 10.1016/j.surfin.2022.102179 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Shared Decision-Making for a Dialysis Modality | The prevalence of kidney failure continues to rise globally. Dialysis is a treatment option for individuals with kidney failure; after the decision to initiate dialysis has been made, it is critical to involve individuals in the decision on which dialysis modality to choose. This review, based on evidence arising from the literature, examines the role of shared decision-making (SDM) in helping those with kidney failure to select a dialysis modality. SDM was found to lead to more people with kidney failure feeling satisfied with their choice of dialysis modality. Individuals with kidney failure must be cognizant that SDM is an active and iterative process, and their participation is essential for success in empowering them to make decisions on dialysis modality. The educational components of SDM must be easy to understand, high quality, unbiased, up to date, and targeted to the linguistic, educational, and cultural needs of the individual. All individuals with kidney failure should be encouraged to participate in SDM and should be involved in the design and implementation of SDM approaches. (C) 2021 International Society of Nephrology.

| ○ | ○ | Article | A cross-species validation of single-beat metrics of cardiac contractility | The assessment of left ventricular (LV) contractility in animal models is useful in various experimental paradigms, yet obtaining such measures is inherently challenging and surgically invasive. In a cross-species study using small and large animals, we comprehensively tested the agreement and validity of multiple single-beat surrogate metrics of LV contractility against the field-standard metrics derived from inferior vena cava occlusion (IVCO). Fifty-six rats, 27 mini-pigs and 11 conscious dogs underwent LV and arterial catheterization and were assessed liar a range of single-heal metrics of LV contractility. All single-beat metrics were tested for the various underlying assumptions required to be considered a valid metric of cardiac contractility, including load-independency, sensitivity to inotropic stimulation, and ability to diagnose contractile dysfunction in cardiac disease. Of all examined single-beat metrics, only LV maximal pressure normalized to end-diastolic volume (EDV), end-systolic pressure normalized to EDV, and the maximal rate of rise of the LV pressure normalized to EDV showed a moderate-to-excellent agreement with their IVCO-derived reference measure and met all the underlying assumptions required to be considered as a valid cardiac contractile metric in both rodents and large-animal models. Our findings demonstrate that single-beat metrics can be used as a valid, reliable method to quantify cardiac contractile function in basic/preclinical experiments utilizing small- and large-animal models | Ahmadian, Mehdi; Williams, Alexandra M.; Mannozzi, Joseph; Konecny, Filip; Hoiland, Ryan L.; Wainman, Liisa; Erskine, Erin; Duffy, Jennifer; Manouchehri, Neda; So, Kitty; Tauh, Keerit; Sala-Mercado, Javier A.; Shortt, Katelyn; Fisk, Shera; Kim, Kyoung-Tae; Streijger, Femke; Foster, Glen E.; Kwon, Brian K.; O'Leary, Donal S.; West, Christopher R. | Univ British Columbia, Fac Educ, Sch Kinesiol, Vancouver, BC, Canada; Univ British Columbia, Int Collaborat Repair Discoveries, Vancouver, BC, Canada; Univ British Columbia, Ctr Chron Dis Prevent & Management, Kelowna, BC, Canada; Univ British Columbia, Fac Med, Dept Cellular & Physiol Sci, Vancouver, BC, Canada; Wayne State Univ, Sch Med, Dept Physiol, Detroit, MI 48201 USA; Transon Scisense Inc, London, ON, Canada; MaRS Ctr Toronto Med Discovery Tower, Toronto, ON, Canada; Univ British Columbia, Vancouver Gen Hosp, Fac Med, Dept Anesthesiol Pharmacol & Therapeut, Vancouver, BC, Canada; Kyungpook Natl Univ Hosp, Sch Med, Dept Neurosurg, Daegu, South Korea; Univ British Columbia Okanagan, Ctr Heart Lung & Vasc Hlth, Sch Hlth & Exercise Sci, Kelowna, BC, Canada | Foster, Glen/AAF-3696-2021; West, Christopher/I-4677-2013; Konecny, Filip/AAZ-1321-2021 | 56443588100; 56390300700; 57217186184; 57203357311; 56346712500; 57193833874; 57193719210; 57919315300; 56685312300; 57194112871; 56899044200; 6507361435; 57194105837; 57212741152; 57201369790; 7801420947; 7403211837; 55851635600; 7201977794; 56232410100 | chris.west@ubc.ca; | JOURNAL OF PHYSIOLOGY-LONDON | J PHYSIOL-LONDON | 0022-3751 | 1469-7793 | 600 | 22 | SCIE | NEUROSCIENCES;PHYSIOLOGY | 2022 | 5.5 | 12.0 | 0.59 | 2025-06-25 | 5 | 6 | END-SYSTOLIC ELASTANCE; PRESSURE-VOLUME RELATION; VENTRICULAR CONTRACTILITY; MYOCARDIAL-INFARCTION; HEART; INDEX; CURVILINEARITY; LOAD; DYSFUNCTION; ANESTHESIA | animal models; cardiac inotropy; single-beat assessment | Animals; Benchmarking; Dogs; Heart Ventricles; Myocardial Contraction; Rats; Stroke Volume; Swine; Swine, Miniature; Ventricular Function, Left; adult; animal experiment; animal model; animal tissue; artery catheterization; Article; biological model; cardiac load independency; controlled study; dog; female; heart beat; heart left ventricle contractility; heart left ventricle enddiastolic volume; heart muscle conduction disturbance; heart muscle contractility; heart stimulation; inferior cava vein obstruction; left ventricular end-systolic pressure; left ventricular pressure; male; mathematical model; minipig; nonhuman; preclinical study; rat; single heart beat; animal; benchmarking; heart contraction; heart left ventricle function; heart stroke volume; heart ventricle; physiology; pig | English | 2022 | 2022-11 | 10.1113/jp283319 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Experimental investigation on the performance of RT-44HC-nickel foam-based heat sinks for thermal management of electronic gadgets | A large amount of heat is generated during the operation of electronic gadgets. Efficient thermal management is crucial for their safe operation and reliability. Phase change materials serve the role to maintain almost constant temperature during the phase change process by absorbing the generated heat. Therefore, the present experimental investigation is performed to single out the thermal performance of nickel foam-based heat sink embedded with RT-44HC paraffin as phase change material (PCM). Nickel foam is used for a high heat transfer area with a minimum reduction in the latent heat of a composite PCM. Results revealed that at the end of the charging process, the heat sink base temperature is reduced by 18.6% when a PCM volume fraction of 0.6 was added to the nickel foam. Furthermore, as the PCM fraction increased, the base temperature decreased further. An 11.6% additional decrease in temperature of the PCM was observed for volume fraction increment from 0.6 to 0.8. The effective thermal conductivity of the composite PCM was noticed to be enhanced by six times as that of a pristine PCM. The discharging process of the composite PCM was delayed compared with that of nickel foam without PCM. However, the sink temperature lies within the safe limits for the composite PCM. The latent heat of the composite PCM was diminished by 23% when effective thermal conductivity was enhanced. Thus, a nickel foam-PCM based heat sink is an efficient source to maintain the electronics temperature within the safe limits. (c) 2022 Elsevier Ltd.
