| ○ | ○ | Article | Substitution Effects in Spin-Polarized (Cr4-xFex)0.5AC (A = Ge, Si, Al) MAX Phases | The use of spintronic devices with a tunable magnetic order on small scales is highly important for novel applications. The MAX phases containing transition metals and/or magnetic ion-substituted lattices attract a lot of attention. In this study, the magnetic and electronic properties of (Cr4-xFex)(0.5)AC (A = Ge, Si, Al) compounds were predicted and investigated within the density functional theory. It was established that single-substituted (Cr3Fe1)(0.5)AC (A = Ge, Si, Al) lattices are favorable in terms of energy. An analysis of the magnetic states of the MAX phases demonstrated that their spin order changes upon substitution of iron atoms for chromium ones. It was found that mostly the (Cr4-xFex)(0.5)GeC and (Cr4-xFex)(0.5)AlC lattices acquire a ferrimagnetic state in contrast to (Cr4-xFex)(0.5)SiC for which the ferromagnetic spin order dominates. It was pointed out that the atomic substitution could be an efficient way to tune the magnetic properties of proposed (Cr4-xFex)(0.5)AC (A = Ge, Si, Al) MAX phases. | Fedorova, Natalja A.; Kovaleva, Alena V.; Olshevskaya, Julia S.; Ivanova, Daria A.; Kozak, Victoria V.; Shubin, Alexander A.; Tarasov, Anton S.; Varnakov, Sergey N.; Ovchinnikov, Sergei G.; Moshkina, Evgeniya M.; Maximova, Olga A.; Avramov, Pavel V.; Tomilin, Felix N. | Fed Res Ctr KSC SB RAS, Kirensky Inst Phys, Krasnoyarsk 660036, Russia; Siberian Fed Univ, Dept Phys & Inorgan Chem, Krasnoyarsk 660041, Russia; Kyungpook Natl Univ, Coll Nat Sci, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea | Olshevskaya, Julia/AAT-9801-2021; Shubin, Aleksandr/J-7025-2012; Moshkina, Evgeniya/K-6415-2015; Tomilin, Felix/F-3763-2014; Kozak, Victoria/HMP-4669-2023; Ivanova, Daria/ABD-4695-2021; Tarasov, Anton/P-3734-2015; Varnakov, Sergey/A-5392-2014 | 57903802100; 57904008500; 58188494300; 57222540909; 57904219000; 57201082401; 55417660400; 6602656052; 14122071800; 56913317900; 57224750071; 7004322420; 6602246772 | a1enka.k.3009000@gmail.com;julia665102.o@gmail.com;taras@iph.krasn.ru;maximo.a@mail.ru;paul.veniaminovich@knu.ac.kr;felixnt@gmail.com; | MAGNETOCHEMISTRY | MAGNETOCHEMISTRY | 2312-7481 | 9 | 6 | SCIE | CHEMISTRY, INORGANIC & NUCLEAR;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 2.6 | 44.3 | 0.13 | 2025-06-25 | 2 | 1 | MAX phase; density functional theory; B3LYP; spintronics; magnetic properties; electronic properties | MAIN-GROUP THERMOCHEMISTRY; MAGNETIC-PROPERTIES; MECHANICAL-PROPERTIES; ELECTRONIC-STRUCTURE; STABILITY; KINETICS; SYSTEMS; CR2GEC; TI | B3LYP; density functional theory; electronic properties; magnetic properties; MAX phase; spintronics | English | 2023 | 2023-06 | 10.3390/magnetochemistry9060147 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | The justice and policy implications of clean energy transition in Africa | Despite the low local energy access rates, Africa is considered a key player in the global energy transition due to its large supply of fossil fuels and a large reserve of critical minerals essential for manufacturing renewable energy components in the energy sector and storage devices in the transportation and electronics sectors. But building a sustainable society at all levels across nations would only come when there exists a just and inclusive energy transition based on the idea of "leave no one behind". While many African countries have embarked on ambitious and transformative transition strategies, and many energy projects classified as "clean" have economic, environmental, and social implications that jeopardize the wellbeing of those already vulnerable to the impacts of climate change. This paper explores the policy implications of the just transition to ensure that efforts to steer Africa towards a lower carbon future are supported by fair, equity, and justice considerations. Our analyses provide valuable evidence for considering a just transition in Africa that will not exacerbate the current socio-economic challenges the region is facing but will support sustained poverty reduction and the achievement of faster economic growth. Our findings show that the African continent's multiple challenges of energy security, economic growth, and affordable access must feature in its clean energy transition. We draw conclusions that an incremental transition emphasizing low-carbon development is the most feasible and pragmatic approach to transform the region's economy and address climate change challenges. | Nsafon, Benyoh Emmanuel Kigha; Same, Noel Ngando; Yakub, Abdulfatai Olatunji; Chaulagain, Deepak; Kumar, Nallapaneni Manoj; Huh, Jeung-Soo | Kyungpook Natl Univ, Inst Global Climate Change & Energy, Daegu, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Energy Convergence & Climate Change, Daegu, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Convergence & Fus Syst Engn, Daegu, South Korea; City Univ Hong Kong, Sch Energy & Environm, Hong Kong, Peoples R China; Ctr Circular Supplies, Hariterde Int Council Circular Econ Res, HICCER, Palakkad, Kerala, India | ; Nallapaneni, Manoj Kumar/R-8605-2018 | 57211664452; 57895613600; 57894905100; 57208742538; 57205074692; 7102258915 | jshuh@knu.ac.kr;luxnsafon@yahoo.ca; | FRONTIERS IN ENVIRONMENTAL SCIENCE | FRONT ENV SCI-SWITZ | 2296-665X | 11 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 3.3 | 44.3 | 3.75 | 2025-06-25 | 32 | 33 | clean energy; just transition; energy justice; policy implications; economic development | RENEWABLE ENERGY; SUSTAINABLE DEVELOPMENT; RURAL ELECTRIFICATION; DETERMINANTS; LABOR | clean energy; economic development; energy justice; just transition; policy implications | English | 2023 | 2023-01-19 | 10.3389/fenvs.2023.1089391 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Zero Energy IoT Devices in Smart Cities Using RF Energy Harvesting | The invention of batteries made it possible to store electricity for many purposes. One of the purposes is to keep the operations of WSN running without any interruptions. The main drawback of sensor nodes is their limited energy sources. The researcher introduces the energy harvesting (EH) concept for IoT-based WSNs to overcome energy limitations and charge the IoT devices. Many energy harvesting techniques have been introduced, such as solar, thermal, and flow-based ones, but radio frequency (RF)-based EH techniques received great attention from researchers due to their easy availability (from TV, radio, and wireless frequencies). In this paper, we have conducted a real-world experiment on Powercast energy harvesting devices and examined the behavior of sensed data in different scenarios, such as indoor, distance (feet/meters), and directional antennas. In our experiments, we have observed that when a device is removed from the charger, the energy scavenging process degrades and reaches a dead state. To stop a device from entering a dead state, we introduce a mobile charger technique to charge the device and find the optimal place for chargers and sensor devices. During mobile charging, we have also observed that when the directional antennas change their angle, the energy scavenging process degrades. To tackle these problems, we introduced two algorithms for directional and omni-directional antennas that efficiently solve the problem. Furthermore, we have obtained results for these scenarios and show that this technique has a promising output. | Zeb, Hassan; Gohar, Moneeb; Ali, Moazam; Rahman, Arif Ur; Ahmad, Waleed; Ghani, Anwar; Choi, Jin-Ghoo; Koh, Seok-Joo | Int Islamic Univ, Dept Comp Sci & Software Engn, Islamabad 44000, Pakistan; Bahria Univ, Dept Comp Sci, Islamabad 44000, Pakistan; Univ Poonch, Dept Elect Engn, Rawalakot 10250, Pakistan; Yeungnam Univ, Dept Informat & Commun Engn, Gyongsan 712749, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | ; Ghani, Anwar/Q-1973-2019; Ali, Moazam/GPG-0733-2022; Rahman, Arif/M-6995-2019 | 58668602900; 36104105300; 57216436657; 57022909600; 58584921800; 55366311900; 7501394023; 8958394800 | mgohar.buic@bahria.edu.pk;sjkoh@knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 12 | 1 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2023 | 2.6 | 44.3 | 2.23 | 2025-06-25 | 13 | 19 | energy harvesting; IoT; EHWSN; smart cities; RF | WIRELESS; SYSTEMS | EHWSN; energy harvesting; IoT; RF; smart cities | English | 2023 | 2023-01 | 10.3390/electronics12010148 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Conservation implications of elucidating the Korean wolf taxonomic ambiguity through whole-genome sequencing | The taxonomic status of the now likely extirpated Korean Peninsula wolf has been extensively debated, with some arguing it represents an independent wolf lineage, Canis coreanus. To investigate the Korean wolf's genetic affiliations and taxonomic status, we sequenced and analysed the genomes of a Korean wolf dated to the beginning of the 20th century, and a captive wolf originally from the Pyongyang Central Zoo. Our results indicated that the Korean wolf bears similar genetic ancestry to other regional East Asian populations, therefore suggesting it is not a distinct taxonomic lineage. We identified regional patterns of wolf population structure and admixture in East Asia with potential conservation consequences in the Korean Peninsula and on a regional scale. We find that the Korean wolf has similar genomic diversity and inbreeding to other East Asian wolves. Finally, we show that, in contrast to the historical sample, the captive wolf is genetically more similar to wolves from the Tibetan Plateau; hence, Korean wolf conservation programmes might not benefit from the inclusion of this specimen. | Hernandez-Alonso, German; Ramos-Madrigal, Jazmin; Sun, Xin; Scharff-Olsen, Camilla Hjorth; Sinding, Mikkel-Holger S.; Martins, Nuno F.

| ○ | ○ | Article | GEOMETRY OF BILINEAR FORMS ON A NORMED SPACE Rn | For every n > 2, let Rnk center dot k be Rn with a norm center dot such that its unit ball has finitely many extreme points more than 2n. We devote to the description of the sets of extreme and exposed points of the closed unit balls of G(2Rnk center dot k) and G3(2Rnk center dot k), where G(2Rnk center dot k) is the space of bilinear forms on Rnk center dot k, and G3(2Rnk center dot k) is the subspace of G(2Rnk center dot k) consisting of symmetric bilinear forms. Let F = G(2Rnk center dot k) or G3(2Rn k center dot k). First we classify the extreme and exposed points of the closed unit ball of F. We also show that every extreme point of the closed unit ball of F is exposed. It is shown that ext BLs(2RnIl center dot Il) = ext BL(2RnIl center dot Il) nG3(2Rnk center dot k) and exp BLs(2RnIl center dot Il) = exp BL(2RnIl center dot Il) n G3(2Rnk center dot k), which expand some results of [18,23, 28, 29, 35, 38, 40, 41, 43]. | Kim, Sung Guen | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | 34769667700 | sgk317@knu.ac.kr; | JOURNAL OF THE KOREAN MATHEMATICAL SOCIETY | J KOREAN MATH SOC | 0304-9914 | 2234-3008 | 60 | 1 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2023 | 0.7 | 44.4 | 0.4 | 2025-06-25 | 1 | 1 | Bilinear forms; symmetric bilinear forms; extreme points; ex-posed points | EXPOSED 2-HOMOGENEOUS POLYNOMIALS; UNIT BALL; EXTREME-POINTS; MULTILINEAR FORMS; HOMOGENEOUS POLYNOMIALS; SUPREMUM NORMS; SMOOTH POINTS; POLARIZATION | Bilinear forms; exposed points; extreme points; symmetric bilinear forms | English | 2023 | 2023-01 | 10.4134/jkms.j220277 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

It is proven that a (2n + 1)-dimensional generalized Sasakian-space-form with beta-Kenmotsu structure satisfying the Fischer-Marsden equation is a conformal gradient soliton. Also, it is shown that a generalized Sasakian-space-form with beta-Kenmotsu structure admitting a gradient Ricci-Bourguignon soliton is either psi\T-k xM(2n+1-k) or gradient eta-Yamabe soliton. | Chaubey, Sudhakar Kumar; Suh, Young Jin | Univ Technol & Appl Sci, IT Dept, Sect Math, POB 77,Postal Code 324, Muscat, Oman; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea | Chaubey, S./ABB-6952-2021 | 36117508600; 7202260479 | sudhakar.chaubey@shct.edu.om;yjsuh@knu.ac.kr; | JOURNAL OF THE KOREAN MATHEMATICAL SOCIETY | J KOREAN MATH SOC | 0304-9914 | 2234-3008 | 60 | 2 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2023 | 0.7 | 44.4 | 7.24 | 2025-06-25 | 18 | 19 | Almost contact metric manifolds; generalized Sasakian-spaceforms; Fischer-Marsden conjecture; Ricci-Bourguignon solitons; symmetric spaces | MANIFOLDS; SUBMANIFOLDS | Almost contact metric manifolds; Fischer-Marsden conjecture; generalized Sasakian-space-forms; Ricci-Bourguignon solitons; symmetric spaces | English | 2023 | 2023-03 | 10.4134/jkms.j220057 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | The complexity of the matroid homomorphism problem | We show that for every binary matroid N there is a graph D(N) such that for the graphic matroid M(G) of a graph G, there is a matroid homomorphism from M(G) to N if and only if there is a graph homomorphism from G to D(N). With this we prove a complexity dichotomy for the problem HomM(N) of deciding if a binary matroid M admits a matroid homomorphism to N. The problem is polynomial time solvable if N has a loop or has no circuits of odd length, and is otherwise NP -complete. We also get dichotomies for the list, extension, and retraction versions of the problem. | Heo, Cheolwon; Kim, Hyobeen; Siggers, Mark | Sungkyunkwan Univ, Appl Algebra & Optimizat Res Ctr, 2066 Seobu Ro, Suwon, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Math Dept, 80 Dae Hak Ro, Daegu 41566, South Korea | 57216587062; 57814030700; 14519683600 | cwheo@skku.edu;mhsiggers@knu.ac.kr;hbkim1029@knu.ac.kr; | ELECTRONIC JOURNAL OF COMBINATORICS | ELECTRON J COMB | 1077-8926 | 30 | 2 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2023 | 0.7 | 44.4 | 0 | 2025-06-25 | 0 | 0 | English | 2023 | 2023-05-19 | 10.37236/11119 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Direct Chlorination of Ethene on ZnO (000(1)over-bar) by Hot Chlorine Atoms | The interaction between ethene and Cl-2 on ZnO(000 (1) over bar) has been investigated using X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption (TPD), and density functional theory (DFT) calculations. At 110 K, the Cl-2 molecule is perpendicularly adsorbed on ZnO(000 (1) over bar). Upon heating, Cl-2 is dissociated on the surface in the temperature range of 200-230 K. When the surface coadsorbed with Cl-2 and ethene is heated, the desorption of 1,2-dichloroethane is observed at similar to 230 K. The desorption temperature is comparable to the dissociation temperature of Cl-2 on ZnO(000 (1) over bar). Ethene does not react with Cl atoms chemisorbed on ZnO(000 (1) over bar). We propose that "hot" Cl atoms, which are produced during thermal dissociation of Cl-2, promote the direct chlorination of C2H4. The energy of the hot Cl atoms is calculated to be maximum 27.5 kcal/mole higher than the energy of the chemisorbed Cl atoms. | Doh, Won Hui; Kondoh, Hiroshi; Ahn, Eonhyoung; Park, Dohyun; Cho, Daeheum; Kim, Chang Min | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Keio Univ, Dept Chem, Yokohama 2238522, Japan | Cho, Daeheum/D-9235-2018; DOH, Won/D-4887-2014 | 35955933400; 35573615200; 58222890900; 58222891000; 55263218400; 55697761200 | daeheumc@knu.ac.kr;cmk@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 127 | 18 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 3.3 | 44.5 | 0.12 | 2025-06-25 | 1 | 1 | ELEY-RIDEAL; HYDROGEN-ATOMS; MECHANISM; SURFACE; ABSTRACTION; OXYGEN; PLATINUM; KINETICS; ETHYLENE; O-2 | Atoms; Chemisorption; Chlorination; Chlorine; Density functional theory; Dissociation; Ethylene; II-VI semiconductors; Temperature programmed desorption; X ray photoelectron spectroscopy; Chlorine atom; Cl atoms; Density-functional theory calculations; Desorption temperatures; Dichloroethane; Dissociation temperature; Energy; Temperature range; Temperature-programmed desorptions; Thermal dissociation; Zinc oxide | English | 2023 | 2023-05-11 | 10.1021/acs.jpcc.2c08706 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Lupeol alleviates atopic dermatitis-like skin inflammation in 2,4-dinitrochlorobenzene/Dermatophagoides farinae extract-induced mice | BackgroundAtopic dermatitis (AD) is a chronic inflammatory skin disease that affects from children to adults widely, presenting symptoms such as pruritus, erythema, scaling, and dryness. Lupeol, a pentacyclic triterpenoid, has anti-inflammatory and antimicrobial activities. Based on these properties, the therapeutic effects of lupeol on skin disorders have been actively studied. In the present study, we aimed to determine the effectiveness of lupeol on AD.MethodsWe utilized tumor necrosis factor (TNF)-alpha/interferon (IFN)-gamma-stimulated keratinocytes and 2, 4-dinitrochlorobenzene/Dermatophagoides farinae extract (DFE)-induced AD mice to confirm the action.ResultsLupeol inhibited TNF-alpha/IFN-gamma-stimulated keratinocytes activation by reducing the expressions of pro-inflammatory cytokines and chemokines which are mediated by the activation of signaling molecules such as signal transducer and activator of transcription 1, mitogen-activated protein kinases (p38 and ERK), and nuclear factor-kappa B. Oral administration of lupeol suppressed epidermal and dermal thickening and immune cell infiltration in ear tissue. Immunoglobulin (Ig) E (total and DFE-specific) and IgG2a levels in serum were also reduced by lupeol. The gene expression and protein secretion of T helper (Th) 2 cytokines, Th1 cytokines, and pro-inflammatory cytokine in ear tissue were decreased by lupeol.ConclusionsThese results suggest that lupeol has inhibitory effects on AD-related responses. Therefore, lupeol could be a promising therapeutic agent for AD. | Bae, Sojung; Jeong, Na-Hee; Choi, Young-Ae; Lee, Byungheon; Jang, Yong Hyun; Lee, Soyoung; Kim, Sang-Hyun | Kyungpook Natl Univ, Sch Med, Dept Pharmacol, CMRI, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biochem & Cell Biol, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Sch Med, Dept Dermatol, 130 Dongdeok Ro, Daegu 41944, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Immunoregulatory Mat Res Ctr, 181 Ipsin Gil, Jeongeup 56212, South Korea | Kim, Sang-Hyun/KQU-4555-2024 | 58201657400; 57194410234; 7404777420; 16304374900; 57016046400; 8537269200; 57210450420 | yhjang@knu.ac.kr;sylee@kribb.re.kr;shkim72@knu.ac.kr; | BMC PHARMACOLOGY & TOXICOLOGY | BMC PHARMACOL TOXICO | 2050-6511 | 24 | 1 | SCIE | PHARMACOLOGY & PHARMACY;TOXICOLOGY | 2023 | 2.8 | 44.5 | 1.59 | 2025-06-25 | 6 | 7 | Atopic dermatitis; House dust mite; Keratinocytes; Lupeol; Skin inflammation | EXPRESSION; TRITERPENE; CELLS | Atopic dermatitis; House dust mite; Keratinocytes; Lupeol; Skin inflammation | Animals; Cytokines; Dermatitis, Atopic; Dermatophagoides farinae; Dinitrochlorobenzene; Disease Models, Animal; Immunoglobulin E; Inflammation; Interferon-gamma; Mice; Mice, Inbred BALB C; Pentacyclic Triterpenes; Plant Extracts; Skin; Tumor Necrosis Factor-alpha; 1 chloro 2,4 dinitrobenzene; alpha tubulin; gamma interferon; glyceraldehyde 3 phosphate dehydrogenase; interleukin 12p35; interleukin 13; interleukin 4; interleukin 5; lupeol; STAT1 protein; tumor necrosis factor; 1 chloro 2,4 dinitrobenzene; cytokine; gamma interferon; immunoglobulin E; lupeol; pentacyclic triterpene; plant extract; tumor necrosis factor; animal cell; animal experiment; animal model; animal tissue; antiinflammatory activity; Article; atopic dermatitis; CD4+ T lymphocyte; controlled study; cytokine production; Dermatophagoides farinae; female; helper cell; human; human cell; immunoglobulin blood level; immunohistochemistry; keratinocyte; mouse; nonhuman; phenotype; protein analysis; protein expression; protein function; protein secretion; randomized controlled trial; real time polymerase chain reaction; Th1 cell; Th2 cell; animal; atopic dermatitis; Bagg albino mouse; Dermatophagoides farinae; disease model; inflammation; metabolism; skin | English | 2023 | 2023-04-25 | 10.1186/s40360-023-00668-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Organic Stable Radical Oligomers as Spin Filters | Single-molecule magnetic junctions provide versatile platforms for use in manipulating spin-polarized currents via fine-tuning the electronic properties of the sandwiched molecule. We employed the nonequilibrium Green's function and spin-polarized density functional theory simulations to investigate the performances of high -spin organic oligoradicals as spin filters sandwiched between two gold electrodes. The spin-polarized current could be obtained using the junction bearing a high-spin molecule with almost unity spin filtering efficiency. Moreover, the spin filtering efficiency could be tuned by varying the number of magnetic units, e.g., di-, tri-, and tetraradicals. Transmission eigenchannel, spin orbital, and density of states analyses revealed how the magnetic exchange interaction in a molecule modulates the dominant electron conducting channels and spin filtering efficiency. The use of a tunable organic magnetic molecular junction system may be a promising approach in manipulating the spin-polarized currents in spintronic devices. | Cho, Daeheum; Lee, Jin Yong | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Sungkyunkwan Univ SKKU, Dept Chem, Suwon 16419, South Korea | Cho, Daeheum/D-9235-2018 | 55263218400; 24478458000 | daeheumc@knu.ac.kr;jinylee@skku.edu; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 127 | 17 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 3.3 | 44.5 | 0.74 | 2025-06-25 | 7 | 6 | ELECTRON-TRANSPORT; GIANT MAGNETORESISTANCE; MOLECULAR ELECTRONICS; GRAPHENE; POLYRADICALS; DIRADICALS; NANOWIRE | Density functional theory; Efficiency; Electronic properties; Spin polarization; Filtering efficiency; Fine tuning; Non equilibrium; Organics; S function; Single molecule; Spin filtering; Spin filters; Spin-polarized currents; Stable radicals; Molecules | English | 2023 | 2023-04-20 | 10.1021/acs.jpcc.3c00179 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Photoinduced Charge Storage with p-Type NiO Nanoplates via Surface Trapped Holes | Existing photoelectrochemical cells for solar energy conversion are hindered by their inability to counteract the ever-changing sunlight conditions, which results in unstable electrical energy output for production of chemicals. Herein, a p-type NiO nanoplate thin film photocathode with rich Ni vacancies is reported, enabling the dual functions of sunlight harvesting and electrical energy storage in a single material system. Band gap excitation of NiO induces surface adsorptions of hydroxide anions and a concomitant storage of in situ-generated photogenerated holes to form NiOOH. In the absence of light, the stored energy in NiOOH is discharged to provide a sustainable current by desorbing the hydroxide anions. The energy storage capacities of the NiO depend on the electrolyte pH and the magnitude of the applied bias. The energy storage capacities of the NiO are greater with alkaline electrolytes due to the availability of hydroxide anions for maintaining the overall charge neutrality in the electrode system. In addition, a sufficiently large negative bias is also required during periodic irradiation to enhance the charge separation efficiency and enable photogenerated holes to be available for charge storage. The feasibility for light-to-electrical energy storage with a single material photocathode is demonstrated, which provides a versatile solution to mitigate the instability of solar irradiation. | Lou, Shi Nee; Paidi, Vinod K.; Lee, Kug-Seung; Park, Hyunwoong; Choi, Wonyong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Korea Inst Energy Technol KENTECH, KENTECH Inst Environm & Climate Technol, Naju 58330, South Korea; Pohang Univ Sci & Technol, Div Environm Sci & Engn, Pohang 37673, South Korea; Tianjin Univ, Sch Chem Engn & Technol, Key Lab Green Chem Technol, Haihe Lab Sustainable Chem Transformat,Minist Edu, Tianjin 300072, Peoples R China; Pohang Accelerator Lab, Pohang 37637, South Korea | ; Lee, Kug-Seung/D-7088-2011; Lou, Shi/C-5395-2013; Choi, Wonyong/F-8206-2010; Park, Hyunwoong/A-1247-2012; Paidi, Vinod K/LPP-3692-2024 | 37117361700; 56764252300; 56953635300; 7601565583; 7402516297 | hwp@knu.ac.kr;wchoi@kentech.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 127 | 11 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 3.3 | 44.5 | 0.37 | 2025-06-25 | 4 | 3 | SELF-PHOTORECHARGEABILITY; CO2; WATER; WO3; PHOTOSYNTHESIS; SPECTROSCOPY; FORMATE; COPPER; FILMS; TIO2 | Alkalinity; Electrolytes; Energy gap; Energy storage; Ions; Irradiation; Nanostructures; Photocathodes; Solar energy; Solar energy conversion; Storage (materials); Charge storage; Electrical energy storages; Energy storage capacity; Hydroxide anions; Nanoplates; P-type; Photo-induced charge; Photogenerated holes; Solar energy conversions; Surface trapped holes; Nickel oxide | English | 2023 | 2023-03-23 | 10.1021/acs.jpcc.3c00452 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | The elbow is the load-bearing joint during arm swing | Background: Arm swing plays a role in gait by accommodating forward movement through trunk balance. This study evaluates the biomechanical characteristics of arm swing during gait. Methods: The study performed computational musculoskeletal modeling based on motion tracking in 15 participants without musculoskeletal or gait disorder. A three-dimensional (3D) motion tracking system using three Azure Kinect (Microsoft) modules was used to obtain information in the 3D location of shoulder and elbow joints. Computational modeling using AnyBody Modeling System was performed to calculate the joint moment and range of motion (ROM) during arm swing. Results: Mean ROM of the dominant elbow was 29.7 degrees +/- 10.2 degrees and 14.2 degrees +/- 3.2 degrees in flexion-extension and pronation-supination, respectively. Mean joint moment of the dominant elbow was 56.4 +/- 12.7 Nm, 25.6 +/- 5.2 Nm, and 19.8 +/- 4.6 Nm in flexion-extension, rotation, and abduction-adduction, respectively. Conclusions: The elbow bears the load created by gravity and muscle contracture in dynamic arm swing movement. | Kang, Bokku; Jung, Gu-Hee; Kholinne, Erica; Jeon, In-Ho; Kwak, Jae-Man | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea; Gyeongsang Natl Univ, Coll Med, Dept Orthoped Surg, Changwon Hosp, Chang Won, South Korea; Univ Trisakti, Dept Orthoped Surg, Fac Med, St Carolus Hosp, Jakarta, Indonesia; Ulsan Univ, Asan Med Ctr, Dept Orthoped Surg, Coll Med, Seoul, South Korea; Eulji Univ, Coll Med, Dept Orthoped Surg, Uijeongbu Eulji Med Ctr, Uijongbu, South Korea | Deslivia, Maria Florencia/IAQ-9858-2023; Kholinne, Erica/AAW-9634-2020 | 58958835300; 57202385117; 57112598600; 7006505004; 57200184383 | jman.kwak@gmail.com; | CLINICS IN SHOULDER AND ELBOW | CLIN SHOULDER ELB | 2288-8721 | 26 | 2 | ESCI | ORTHOPEDICS | 2023 | 1.8 | 44.5 | 0.61 | 2025-06-25 | 7 | 3 | Elbow; Load bearing; Range of motion; Stiffness | GAIT PARAMETERS; KINECT; TRACKING | Elbow; Load bearing; Range of motion; Stiffness | English | 2023 | 2023-06 | 10.5397/cise.2023.00101 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
