| ○ | ○ | Article | Microstructural Control Strategy Based on Optimizing Laser Powder Bed Fusion for Different Hastelloy X Powder Size | In additive manufacturing (AM), the powder properties and laser powder bed fusion (LPBF) process parameters influence the quality of materials and building parts. However, the relationship between the size of the powder, LPBF process parameters, and mechanical properties is not well-established. In addition, Hastelloy X (HX) is attracting attention for its excellent high-temperature properties, but it is difficult to process, such as by cutting and milling, because of its high hardness and high ductility. This can be overcome by applying the AM process. We compared the LPBF window process maps for two HX powders of different sizes. Despite their small difference of 19.7% in particle size, it was confirmed that the difference in laser power was more than 40 W, the difference in scan speed was more than 100 mm/s, and the difference in energy density was more than 20% under the optimal process conditions. The as-built specimen had a larger molten-pool size as the energy density was higher, which resulted in the differences in mechanical properties at room temperature and high temperature (816 degrees C). We considered the control of the size of the powder to obtain the properties required for each temperature condition. The microstructures and mechanical properties of the as-built LPBF specimens were also investigated and compared with those of cast HX. Because of the rapid melting and solidification processes in LPBF, the as-built HX exhibited nano-sized dendrite structures and large internal strain energy. This resulted in the as-built LPBF exhibiting a higher room-temperature tensile strength than the cast material. Under high-temperature conditions, the grain boundary of the as-built LPBF acts as a sliding path, and the as-built LPBF HX showed significantly better high-temperature tensile strength characteristics than the cast HX. | Jang, Jee-Eun; Kim, Woosung; Sung, Ji-Hyun; Kim, Young-Joo; Park, Sung-Hyuk; Kim, Da-Hye | Korea Inst Ind Technol, Smart Mfg Technol R&D Grp, Daegu 42994, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; KEPCO KPS Global Inst Technol, Dev Inst Plant Technol Grp, Naju 58326, South Korea | ; Kim, Woo/D-2733-2015; Park, Sung-Hyuk/AAE-6726-2022 | 57660564800; 57200625190; 23482644100; 57659310000; 54786002500; 56997864800 | dahye.kim@kitech.re.kr; | MATERIALS | MATERIALS | 1996-1944 | 15 | 18 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 3.4 | 24.7 | 0.33 | 2025-06-25 | 4 | 4 | additive manufacturing; laser powder bed fusion; Hastelloy X; microstructure; mechanical property | SURFACE-ROUGHNESS; BEHAVIOR; TEMPERATURE; COMPONENTS; DENSITY; CREEP | additive manufacturing; Hastelloy X; laser powder bed fusion; mechanical property; microstructure | 3D printers; Additives; Density (specific gravity); Grain boundaries; Particle size; Strain energy; Tensile strength; Control strategies; Energy density; Fusion process; Hastelloy X; Laser powder bed fusion; Laser powders; Microstructural control; Powder bed; Powder size; Process parameters; Microstructure | English | 2022 | 2022-09 | 10.3390/ma15186191 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Pilot Evaluation of Sealer-Based Root Canal Obturation Using Epoxy-Resin-Based and Calcium-Silicate-Based Sealers: A Randomized Clinical Trial | The purpose of this randomized controlled clinical trial was to assess the short-term clinical effectiveness of sealer-based root canal obturation using calcium-silicate-based sealer (CSBS) and epoxy-resin-based sealer (ERBS). A total of eighty patients (eighty teeth) were enrolled and seventy-two patients (seventy-two teeth) were randomly assigned into four different sealer groups: AH Plus (AH, Dentsply Sirona), ADseal (AD, Meta Biomed), CeraSeal (CS, Meta Biomed), or EndoSeal TCS (ES, Maruchi). At the first visit, root canal treatment was performed using ProTaper. Next, the NiTi file system and passive ultrasonic irritation was applied with 2.5% NaOCl. At the second visit, the teeth were obturated with a sealer-based obturation technique using the assigned sealer. The quality of filling obturation was evaluated with postoperative radiographs in terms of the presence of voids and sealer extrusion. The patients were recalled at 1-week, 1-month, and 3-month intervals, and pain levels were measured using visual analog scales (VAS), and clinical examination performed with percussion and palpation. Radiographs were also taken. The results were statistically compared by using the chi(2) test or Fisher exact test. Among the 80 teeth included, 72 teeth received allocated intervention and 71 teeth were included in the analysis (98.6% recall). There was no significant difference among the sealers in void and sealer extrusion (p > 0.05). Postoperative pain was not indicated prominently regardless of the type of sealer. For a 3-month follow-up period, all cases were maintained successfully except for one case from AD. According to the findings, there was no significant difference between CSBS and ERBS in terms of postoperative pain or the healing process, and the variation in filling quality appears to be linked to the properties of each product. | Song, Minju; Park, Min-Gyu; Kwak, Sang-Won; Kim, Ruben H.; Ha, Jung-Hong; Kim, Hyeon-Cheol | Dankook Univ, Coll Dent, Dept Conservat Dent, Cheonan 31116, South Korea; Pusan Natl Univ, Sch Dent, Dent Res Inst, Dept Conservat Dent, Yangsan 50612, South Korea; Univ Calif Los Angeles, David Geffen Sch Med, UCLA Jonsson Comprehens Canc Ctr, Los Angeles, CA 90095 USA; Kyungpook Natl Univ, Coll Dent, Dept Conservat Dent, Daegu 41566, South Korea | Kim, Hyeon/AAQ-9057-2021; Song, Minju/AFV-0943-2022 | 57202083743; 57223113437; 54787794900; 8967104200; 55549831900; 35746710200 | minju81s@dankook.ac.kr;hihoney22@naver.com;endokwak@pusan.ac.kr;rkim@dentistry.ucla.edu;endoking@knu.ac.kr;golddent@pusan.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 15 | 15 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 3.4 | 24.7 | 1.67 | 2025-06-25 | 17 | 21 | calcium silicate; root canal filling; sealer; sealer-based obturation | POSTOPERATIVE PAIN; AH PLUS; QUALITY; TEETH | calcium silicate; root canal filling; sealer; sealer-based obturation | Filling; Hydraulic structures; Silicates; Titanium alloys; Clinical effectiveness; Filesystem; Randomized clinical trials; Randomized controlled clinical trials; Root canal filling; Root canal obturation; Root canal treatment; Sealer; Sealer-based obturation; Ultrasonic irritation; Extrusion | English | 2022 | 2022-08 | 10.3390/ma15155146 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Prediction of Concrete Fragments Amount and Travel Distance under Impact Loading Using Deep Neural Network and Gradient Boosting Method | In the present study, the amount of fragments generated and their travel distances due to vehicle collision with concrete median barrier (CMB) was analyzed and predicted. In this regard, machine learning was applied to the results of numerical analysis, which were developed by comparing with field test. The numerical model was developed using smoothed particle hydrodynamics (SPH). SPH is a mesh-free method that can be used to predict the amount of fragments and their travel distances from concrete structures under impact loading. In addition, deep neural network (DNN) and gradient boosting machine (GBM) were also employed as machine learning methods. In this study, the results of DNN, GBM, and numerical analysis were then compared with the conducted field test. Such comparisons revealed that numerical analysis generated lower error than both DNN and GBM. When prediction results of both the amount of fragments and their travel distances were considered, the result of DNN showed smaller errors than that of GBM. Therefore, in studies where machine learning is used to predict the amount of fragments and their travel distances, careful selection of an appropriate method from the various available machine learning methods such as DNN, GBM, and random forest is absolutely important. | Kim, Kyeongjin; Kim, WooSeok; Seo, Junwon; Jeong, Yoseok; Lee, Meeju; Lee, Jaeha | Natl Korea Maritime & Ocean Univ, Major Civil Engn, 727 Taejong Ro, Busan 49112, South Korea; Chungnam Natl Univ, Dept Civil Engn, 99 Daehak 99, Daejeon 34134, South Korea; South Dakota State Univ, Dept Civil & Environm Engn, Brookings, SD 57007 USA; Kyungpook Natl Univ, Dept Construction & Disaster Prevent Engn, 2559 Kyungsangdae Ro, Sangju 37224, South Korea; Natl Korea Maritime & Ocean Univ, Major Civil & Environm Engn, 727 Taejong Ro, Busan 49112, South Korea; Natl Korea Maritime & Ocean Univ, Interdisciplinary Major Ocean Renewable Energy En, Busan 49112, South Korea | ; Lee, Jaeha/AAD-3173-2022; Seo, Junwon/AAH-8029-2019 | 55976314300; 56286036900; 24469249700; 54980727300; 57426304500; 57014428600 | kkj4159@naver.com;wooseok@cnu.ac.kr;junwon.seo@sdstate.edu;ysjeong@knu.ac.kr;meeju9988@naver.com;jaeha@kmou.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 15 | 3 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 3.4 | 24.7 | 0.67 | 2025-06-25 | 7 | 8 | concrete median barrier; gradient boosting machine; smoothed particle hydrodynamics; deep neural network; artificial neural network; fragments; travel distance | REINFORCED-CONCRETE; SIMULATIONS | Artificial neural network; Concrete median barrier; Deep neural network; Fragments; Gradient boosting machine; Smoothed particle hydrodynamics; Travel distance | Adaptive boosting; Concretes; Decision trees; Forecasting; Hydrodynamics; Numerical analysis; Concrete median barrier; Field test; Fragment; Gradient boosting; Gradient boosting machine; Impact loadings; Machine learning methods; Median barriers; Smoothed particle hydrodynamics; Travel distance; Deep neural networks | English | 2022 | 2022-02 | 10.3390/ma15031045 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Preparation of the Heterogeneous Saponified Poly(Vinyl Alcohol)/Poly(Methyl Methacrylate-Methallyl Alcohol) Blend Film | For the first time, poly(vinyl alcohol) (PVA)/poly(methyl methacrylate-methallyl alcohol) (P(MMA-MAA)) (9:1, 7:3, 5:5) blend films were made simultaneously using the saponification method in a heterogeneous medium from poly(vinyl acetate) (PVAc)/poly(methyl methacrylate) (PMMA) (9:1, 7:3, 5:5) blend films, respectively. The surface morphology and characteristics of the films were investigated using optical microscopy (OM), atomic force microscopy (AFM), X-ray diffractometer (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Moreover, the effect of the PVAc content on the degree of saponification (DS) of the PVAc/PMMA films were evaluated and revealed that the obtained DS value increased with the increase in PVAc content in the PVAc/PMMA blend films. According to the OM results, the saponified films demonstrated increased surface roughness compared with the unsaponified films. The AFM images revealed morphological variation among the saponified PVAc/PMMA blend films with different mass ratios of 9:1, 7:3, and 5:5. According to the DSC and TGA results, all blend film types exhibited higher thermal property after the saponification treatment. The XRD and FTIR results confirmed the conversion of the PVAc/PMMA into PVA/P(MMA-MAA) films. Thus, our present work may give a new idea for making blend film as promising medical material with significant surface properties based on hydrophilic/hydrophobic strategy. | Yang, Seong Baek; Jeong, Dae Won; Lee, Jungeon; Yeasmin, Sabina; Kim, Chang-Kil; Yeum, Jeong Hyun | Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea | ; Yang, Seong/AAP-1745-2020 | 56258526300; 57191710603; 57559595700; 57216565706; 7409880701; 6602257098 | ysb@knu.ac.kr;wjdeodnjs@gmail.com;dlwjddjs2@gmail.com;yeasminsabina44@yahoo.com;ckkim@knu.ac.kr;jhyeum@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 15 | 7 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 3.4 | 24.7 | 0.42 | 2025-06-25 | 4 | 5 | poly(vinyl acetate); poly(vinyl alcohol); poly(methyl methacrylate); solution casting; saponified film | SUSPENSION POLYMERIZATION; MECHANICAL-PROPERTIES; OPTICAL-PROPERTIES; VINYL-ACETATE; PMMA; MICROSPHERES; BEHAVIOR; COPOLYMERIZATION; STARCH | poly(methyl methacrylate); poly(vinyl acetate); poly(vinyl alcohol); saponified film; solution casting | Differential scanning calorimetry; Esters; Film preparation; Fourier transform infrared spectroscopy; Hydrolysis; Hydrophilicity; Morphology; Surface morphology; Surface roughness; Thermogravimetric analysis; X ray diffraction; Poly (vinyl alcohol) (PVA); Poly(methyl methacrylate); Poly(vinyl acetate); Poly(vinyl alcohol); Poly(vinyl alcohol) (PVA); Poly-methyl methacrylates; Saponified film; Solution casting; Polyvinyl alcohols | English | 2022 | 2022-04 | 10.3390/ma15072439 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Thermoelectric Properties of Cu2Te Nanoparticle Incorporated N-Type Bi2Te2.7Se0.3 | To develop highly efficient thermoelectric materials, the generation of homogeneous heterostructures in a matrix is considered to mitigate the interdependency of the thermoelectric compartments. In this study, Cu2Te nanoparticles were introduced onto Bi2Te2.7Se0.3 n-type materials and their thermoelectric properties were investigated in terms of the amount of Cu2Te nanoparticles. A homogeneous dispersion of Cu2Te nanoparticles was obtained up to 0.4 wt.% Cu2Te, whereas the Cu2Te nanoparticles tended to agglomerate with each other at greater than 0.6 wt.% Cu2Te. The highest power factor was obtained under the optimal dispersion conditions (0.4 wt.% Cu2Te incorporation), which was considered to originate from the potential barrier on the interface between Cu2Te and Bi2Te2.7Se0.3. The Cu2Te incorporation also reduced the lattice thermal conductivity, and the dimensionless figure of merit ZT was increased to 0.75 at 374 K for 0.4 wt.% Cu2Te incorporation compared with that of 0.65 at 425 K for pristine Bi2Te2.7Se0.3. This approach could also be an effective means of controlling the temperature dependence of ZT, which could be modulated against target applications. | Jung, Yong-Jae; Kim, Hyun-Sik; Won, Jong Ho; Kim, Minkyung; Kang, Minji; Jang, Eun Young; Nguyen Vu Binh; Kim, Sang-il; Moon, Kyoung-Seok; Roh, Jong Wook; Nam, Woo Hyun; Koo, Sang-Mo; Oh, Jong-Min; Cho, Jung Young; Shin, Weon Ho | Kwangwoon Univ, Dept Elect Mat Engn, Seoul 01897, South Korea; Univ Seoul, Dept Mat Sci & Engn, Seoul 02504, South Korea; Kookmin Univ, Dept Chem, Seoul 02707, South Korea; Korea Inst Ceram Engn & Technol KICET, Energy & Environm Div, Jinju 52851, South Korea; Gyeongsang Natl Univ, Dept Mat Engn & Convergence Technol, Jinju 52828, South Korea; Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, Sangju 37224, South Korea | Jung, Yong-Jae/ITV-9598-2023; Moon, Kyoung-Seok/AAG-5555-2019; Shin, Weon/AAH-4031-2020; Kim, Sung/A-4747-2013; Won, Jong Ho/AAT-1550-2021 | 57562004000; 56526077500; 57191276949; 57192294639; 57561422400; 57562004100; 57226410587; 36171889900; 23470191000; 25638796100; 36351054000; 34872660400; 35219258600; 55261296200; 57204152565 | yongjae6945@kw.ac.kr;hyunsik.kim@uos.ac.kr;ballnet09@kookmin.ac.kr;minkyungkim@kw.ac.kr;rkdalsw15600@naver.com;dmsduddl0212@naver.com;nguyenvubinh20121995@gmail.com;sang1.kim@uos.ac.kr;ksky.moon@gnu.ac.kr;jw.roh@knu.ac.kr;whnam@kicet.re.kr;smkoo@kw.ac.kr;jmoh@kw.ac.kr;jycho93@kicet.re.kr;weonho@kw.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 15 | 6 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 3.4 | 24.7 | 0.75 | 2025-06-25 | 9 | 9 | thermoelectric; n-type; Cu2Te; composite | BISMUTH-ANTIMONY TELLURIDE; PERFORMANCE | composite; Cu<sub>2</sub>Te; n-type; thermoelectric | Bismuth compounds; Copper compounds; Dispersions; Selenium compounds; Tellurium compounds; Temperature distribution; Thermal conductivity; Thermoelectric equipment; Thermoelectricity; Highpower-factor; Homogeneous dispersions; matrix; N-type; N-type materials; Optimal dispersion; Thermo-Electric materials; Thermoelectric; Thermoelectric material; Thermoelectric properties; Nanoparticles | English | 2022 | 2022-03 | 10.3390/ma15062284 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Biosurfactant lipopeptides and polyketide biosynthetic gene in rhizobacterium Achromobacter kerstersii to induce systemic resistance in tomatoes | Discovery of novel fungicides for disease management improve on our panoply of known pharmaceuticals. The prime mechanisms of action of agricultural fungicides are by pathogen antagonism or destruction and induced plant systemic resistance. In this study, we describe lipopeptides from tomato rhizobacterium, Achromobacter kerstersii JKP9 exhibiting effective antagonism to Fusarium wilt. Induced systemic resistance potentials were screened after inoculation of bioactive rhizosphere bacterial consortium (Mycoclear) into tomato rhizosphere. Mild biosurfactant properties were observed in drop collapse, and oil displacement assays. The isolated lipopeptides were chemically characterized using FT-IR, HR-NMR. Fatty acid tails were profiled by GC-MS/MS and lipopeptide types were predicted in LC-MS/MS. Polyketide synthase II gene (PKS2) for antibiotic biosynthesis was detected in Achromobacter kerstersii JKP9. Fungal membrane damages and cell wall disruptions due to the interactions of lipopeptides were studied using live/dead fluorescent probes in a dosage-dependent manner. The characterized lipopeptides exhibited broad spectrum of antifungal action against virulent Fusarium spp. and Sarocladium sp. Hence, our findings support cultivable rhizobacteria and their lipopeptides, as promising rhizotechnological tools, rather than synthetics to warrant wilt-free landscape for agriculture. | Vijay, Karuppiah; Hassan, Saqib; Govarthanan, Muthusamy; Kavitha, Thangavel | Alagappa Univ, Dept Microbiol, Sci Campus, Karaikkudi, Tamil Nadu, India; Pondicherry Univ, Sch Life Sci, Dept Microbiol, Pondicherry, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Biomat, Chennai 600077, India; Alagappa Univ, Dept Microbiol, Karakudi 630003, Tamil Nadu, India | ; Govarthanan, Muthusamy/C-1491-2014; HASSAN, SAQIB/AAX-7681-2021; Karuppiah, Vijay/GMW-9090-2022; Muthusamy, Govarthanan/C-1491-2014 | 57216493201; 56937745800; 54881927600; 57214889652 | karuppiahvijay@gmail.com;hassansaqib1@gmail.com;gova.muthu@gmail.com;kavithat@alagappauniversity.ac.in; | RHIZOSPHERE | RHIZOSPHERE-NETH | 2452-2198 | 23 | SCIE | PLANT SCIENCES;SOIL SCIENCE | 2022 | 3.7 | 24.9 | 0.52 | 2025-06-25 | 5 | 5 | Lipopeptides; Rhizobacteria; Biosurfactants; Biocontrol; Achromobacter kerstersii | BACILLUS; TEMPERATURE; PSEUDOMONAS | Achromobacter kerstersii; Biocontrol; Biosurfactants; Lipopeptides; Rhizobacteria | English | 2022 | 2022-09 | 10.1016/j.rhisph.2022.100558 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Letter | Characterization of Hall Factor with Seebeck Coefficient Measurement | The density-of-states effective mass (m(d)*) is commonly obtained by fitting the equation, S = (8 pi(2)k(B)(2)/3eh(2))m(d)*T(pi/3n)(2/3) (S, T, and n are the Seebeck coefficient, temperature, and the carrier concentration, respectively), to n-dependent S measurement. However, n is not a measurable parameter. It needs to be converted from the measured Hall carrier concentration (n(H)) using the Hall factor (r(H) = n/n(H)). The r(H) of material can be estimated by Single Parabolic Band (SPB) model if the band that contributed to transport is approximated to be parabolic and acoustic phonons dominantly scatter its carriers. However, the measurable n(H) is often used instead of n when utilizing the above equation due to the complex Fermi integrals involved in the SPB model calculation. Consequently, the m(d)* estimated from the above equation while using n(H) would be inaccurate. We propose the equation r(H) = 1.17 - [0.216 / {1 + exp((vertical bar S vertical bar - 101) / 67.1)}] as a simple and accurate method to obtain the r(H) from the measured S to facilitate the conversion from n(H) to n and eventually increase the accuracy of m(d)* estimated from the above equation. | Lim, Jong-Chan; Kim, Se Yun; Shin, Weon Ho; Kim, Sang-il; Roh, Jong Wook; Yang, Heesun; Kim, Hyun-Sik | Hongik Univ, Dept Mat Sci & Engn, Seoul 04066, South Korea; Samsung Adv Inst Technol, Inorgan Mat Lab, Suwon 16678, South Korea; Kwangwoon Univ, Dept Elect Mat Engn, Seoul 01897, South Korea; Univ Seoul, Dept Mat Sci & Engn, Seoul 02504, South Korea; Kyungpook Natl Univ, Mat Sci & Engn, Gyeongsangbuk Do 37224, South Korea | ; Kim, Sung/A-4747-2013; Shin, Weon/AAH-4031-2020; Kim, Seung/N-5248-2019 | 57221705695; 57203210313; 57204152565; 36171889900; 25638796100; 7408619037; 56526077500 | hyunsik.kim@uos.ac.kr; | ACS APPLIED ENERGY MATERIALS | ACS APPL ENERG MATER | 2574-0962 | 5 | 4 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 6.4 | 24.9 | 0.82 | 2025-06-25 | 9 | 10 | thermoelectric; Hall factor; Hall carrier concentration; density-of-states effective mass; Seebeck coefficient | HIGH-THERMOELECTRIC PERFORMANCE; CONVERGENCE; TRANSPORT; BANDS | density-of-states effective mass; Hall carrier concentration; Hall factor; Seebeck coefficient; thermoelectric | Seebeck coefficient; Densities of state; Density-of-state effective mass; Effective mass; Hall carrier concentrations; Hall factor; Measurable parameters; Parabolic band model; Parabolics; Seebeck coefficient measurement; Thermoelectric; Carrier concentration | English | 2022 | 2022-04-25 | 10.1021/acsaem.2c00549 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sulfur-Treated ITO Back Contact for Enhanced Performance of Semitransparent Ultrathin Cu(In,Ga)Se2 Solar Cells | Ultrathin Cu(In,Ga)Se2 (CIGSe) solar cells can be fabricated using various back contact materials. Among those back contact materials, transparent conductive oxides have enabled a lot of applications in semitransparent ultrathin (STUT) CIGSe solar cells. Especially, tin-doped indium oxide (ITO) has been used as a back contact material to fabricate STUT CIGSe solar cells because of its high transparency and conductivity. However, the CIGSe absorber layer deposited on ITO substrates is known to form an undesirable GaOx layer at high processing temperatures owing to Ga diffusion. To improve the back contact properties at the CIGSe and ITO interface, sulfur treatment of the ITO back electrode was conducted. Its rear-side interface analysis indicated that the GaOx interfacial layer changed to a mixed interfacial layer upon undergoing sulfur treatment, wherein the GaSx and GaOx phases were formed at the CIGSe/ITO rear-side interface. A fundamental investigation of the material properties implied that GaOx and GaSx have different energy band alignments at the rear-side interface and that GaSx can be more helpful for hole extraction than the GaOx phase. After fabrication of the STUT CIGSe solar cell, the power conversion efficiency with an optimal sulfur-treatment time of 5 min increased to 9.0% while that of the control solar cell on bare ITO (i.e., without sulfur treatment) remained at 7.0%. The results suggested that the composition and characteristics of the interfacial layer had a substantial impact on the photovoltaic properties of the STUT CIGSe solar cells. | Kim, Dongryeol; Saifullah, Muhammad; Jo, Yonghee; An, Jin Gi; Cho, Jun-Sik; Ahn, SeJin; Gwak, Jihye; Lee, Ho Seong; Park, Joo Hyung | Korea Inst Energy Res KIER, Photovolta Res Dept, Daejeon 34129, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Pakistan Inst Nucl Sci & Technol PINSTECH, Islamabad 45650, Pakistan; Jeonbuk Natl Univ, Dept Elect Engn, Jeonju 54896, South Korea; Jeonbuk Natl Univ, Smart Grid Res Ctr, Jeonju 54896, South Korea | Park, Joo Hyung/AAL-5247-2020 | 57194069208; 57189578169; 57646774900; 57861257100; 7403535861; 55701538100; 15762620400; 55706810400; 57193059568 | hs.lee@knu.ac.kr;joopark@kier.re.kr; | ACS APPLIED ENERGY MATERIALS | ACS APPL ENERG MATER | 2574-0962 | 5 | 9 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 6.4 | 24.9 | 0.16 | 2025-06-25 | 2 | 2 | ultrathin; Cu(In; Ga)Se2 (CIGSe); semitransparent; sulfur treatment; CIGSe/ITO interface | OXIDE BACK; INTERFACE; SULFIDE; IMPACT; LAYER | CIGSe/ITO interface; Cu(In,Ga)Se<sub>2</sub>(CIGSe); semitransparent; sulfur treatment; ultrathin | Conductive materials; Gallium compounds; Indium compounds; Processing; Selenium compounds; Solar power generation; Sulfur; Tin oxides; Back contact; Contact material; Cu(in,ga)se2(cu(in,ga)se2); Cu(in,ga)se2/ITO interface; Interfacial layer; Performance; Rear side; Semitransparent; Sulfur treatment; Ultra-thin; Solar cells | English | 2022 | 2022-09-26 | 10.1021/acsaem.2c01350 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Cooperative vehicular networks: An optimal and machine learning approach | Intelligent Transport Systems (ITS) provide a promising technology to enhance road safety. The vehicular standard wireless access in vehicular environment (WAVE), also known as dedicated short-range communication (DSRC), can assist in reducing the number of deadly crashes. However, DSRC has a limited range. To enhance the network coverage, roadside units (RSUs) are placed along the road. However, the placement of RSUs at every instant increases the infrastructure cost. In this paper, we proposed the cooperative vehicular architecture, with network function virtualization (NFV) enabled RSU inside the mobile edge computing (MEC) unit. RSUs are only placed in the dense traffic region. We applied the Long short-term memory (LSTM) based machine-learning algorithm to predict the traffic flow based on the vehicle information table (VIT) maintained at the MEC unit. NFV is implemented at the top of RSU. Based on predicted traffic density it assists RSU to enhance its coverage range by exploiting the transmit power. Furthermore, MEC is also responsible for cooperative relay -based communication. Optimal stopping theory is modeled to select the best candidate relay node immediately. In this paper, we tested the proposed scheme in actual on-road vehicles and through simulations performed in network simulator NS-3. | Saad, Malik Muhammad; Khan, Muhammad Toaha Raza; Srivastava, Gautam; Jhaveri, Rutvij H.; Islam, Mahmudul; Kim, Dongkyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Pandit Deendayal Energy Univ, Sch Technol, Dept Comp Sci & Engn, Gandhinagar, India; Brandon Univ, Dept Math & Comp Sci, Brandon, MB, Canada; China Med Univ, Res Ctr Interneural Comp, Taichung, Taiwan | Jhaveri, Rutvij/A-5354-2018; Saad, Malik/ABF-9433-2021; Srivastava, Gautam/N-5668-2019; Khan, Turyalai/HPH-0061-2023 | 57220715290; 57202044597; 57202588447; 55201717100; 57223681377; 35753648800 | maliksaad@knu.ac.kr;toaha@knu.ac.kr;srivastavag@brandonu.ca;rutvij.jhaveri@sot.pdpu.ac.in;mislam@knu.ac.kr;dongkyun@knu.ac.kr; | COMPUTERS & ELECTRICAL ENGINEERING | COMPUT ELECTR ENG | 0045-7906 | 1879-0755 | 103 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2022 | 4.3 | 25.0 | 0.81 | 2025-06-25 | 9 | 11 | VANET; DSRC; Network function virtualization (NFV); MEC; Cooperative communication | FRAMEWORK; INTERNET; DELAY | Cooperative communication; DSRC; MEC; Network function virtualization (NFV); VANET | Computation theory; Dedicated short range communications; Intelligent systems; Intelligent vehicle highway systems; Learning algorithms; Mobile edge computing; Motor transportation; Network function virtualization; Reinforcement learning; Roads and streets; Street traffic control; Vehicle to vehicle communications; Vehicular ad hoc networks; Virtual reality; Computing units; Intelligent transport; Machine learning approaches; Network function virtualization; Road safety; Roadside units; Transport systems; VANET; Vehicular networks; Wireless access; Cooperative communication | English | 2022 | 2022-10 | 10.1016/j.compeleceng.2022.108348 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Improvement of the optical characteristics of PVA/PVP blend with different concentrations of SnS2/Fe | Polyvinyl alcohol (PVA)/polyvinylpyrrolidone (PVP; weight 7:3) polymer blends doped with different ratios (1 wt%, 3 wt%, 5 wt%, and 10 wt%) from nano SnS2/Fe are developed using casting and thermolysis procedures. Rietveld analysis showed that Fe is incorporated into the SnS2 lattice forming a single hexagonal phase with an average crystallite size of 6 nm along [00l] direction and 15 nm along [h00] direction. X-ray diffraction together with Fourier transform infrared data is used to examine the homogeneity distribution of the nanofiller over the blend matrix. The effect of doping on the absorbance, transmittance, extinction coefficient, refractive index, direct and indirect optical band gaps, and other dispersion parameters of the blend is studied in detail. The nature of electronic transitions in the different blends was determined using Tauc's relation and the dielectric loss parameter. As the weight concentrations of SnS2/Fe dopants increased, the nonlinear optical parameters are increased relative to the undoped PVA/PVP polymer blend. The influence of the different excitation wavelengths and the amount of nanofillers on the fluorescence spectra from different blends are also investigated. | El-naggar, Ahmed M.; Heiba, Zein K.; Mohamed, Mohamed Bakr; Kamal, Amgad M.; Osman, Mohamed M.; Albassam, Abdullah A.; Lakshminarayana, Gandham | King Saud Univ, Coll Sci, Phys & Astron Dept, Riyadh, Saudi Arabia; Ain Shams Univ, Fac Sci, Phys Dept, Cairo, Egypt; Al Azhar Univ, Boys Branch, Phys Dept, Fac Sci, Cairo, Egypt; KA CARE Energy Res & Innovat Ctr Riyadh, Riyadh, Saudi Arabia; Kyungpook Natl Univ, Intelligent Construct Automat Ctr, Daegu, South Korea | Mohamed, Mohamed Bakr/P-2194-2014; Mohamed, Mohamed/P-2194-2014; El-Naggar, Ahmed/H-9098-2018; Gandham, Lakshminarayana/AAU-6162-2020; Osman, Muhammad/ABB-1026-2021 | 7201947258; 6602591867; 37018029400; 36719759500; 57225724020; 35306540300; 57194637883 | mbm1977@yahoo.com; | JOURNAL OF VINYL & ADDITIVE TECHNOLOGY | J VINYL ADDIT TECHN | 1083-5601 | 1548-0585 | 28 | 1 | SCIE | CHEMISTRY, APPLIED;MATERIALS SCIENCE, TEXTILES;POLYMER SCIENCE | 2022 | 2.7 | 25.0 | 4.16 | 2025-06-25 | 66 | 59 | dopant; optical; PVA; PVP blend; SnS2; Fe concentration; structure | POLYMER; NANOCOMPOSITE; FABRICATION; ABSORPTION; NANO | dopant; optical; PVA/PVP blend; SnS<sub>2</sub>/Fe concentration; structure | Dielectric losses; Energy gap; IV-VI semiconductors; Refractive index; Rietveld analysis; Semiconducting tin compounds; Fourier transform infrared; Hexagonal phasis; Nanofiller; Optical characteristics; Optical-; Polyvinyl alcohol/PVP blend; Polyvinylpyrrolidones; SnS2/fe concentration; Thermolyses; X- ray diffractions; Crystallite size | English | 2022 | 2022-02 | 10.1002/vnl.21868 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Pain Relief After Selective Nerve Root Block as a Predictor of Postoperative Functional Outcome in Patients with Degenerative Lumbar Spinal Stenosis Patients Undergoing Decompressive Surgery | Study Design. Retrospective study of data collected prospectively. Objective. To investigate changes in the degree of lower leg radiating pain (LLRP) after selective nerve root block (SNRB) and to evaluate associations of this change with postoperative improvements in symptom severity, functional outcomes, and quality of life. Summary of Background Data. SNRB is routinely performed as an initial treatment for lumbar foraminal or lateral recess stenosis with LLRP. The degree of improvement after SNRB has been suggested to predict the improvement in postoperative pain and functional outcomes. However, there have been no studies on the predictive value of this parameter. Methods. We enrolled 60 patients who underwent SNRB followed by decompressive surgery. They were divided into three groups. The degree of improvement was evaluated as a percentage of the pre-injection values. Functional outcomes of the spine were assessed using the Oswestry Disability Index (ODI) and Roland-Morris Disability Questionnaire (RMDQ). Quality of life was assessed using the 36-item Short Form Survey (SF-36) physical component score (PCS) and mental component score (MCS). The degree of LLRP was measured preoperatively and at 6, 12, and 24 months after surgery. These functional outcomes were evaluated preoperatively and at 12 and 24 months after surgery. Results. The improvement in LLRP in the short term (6 hours after SNRB) was found to be statistically significantly associated with the improvement in LLRP at 12 months after SNRB (P = 0.044, correlation coefficient = 0.261). No relationship between pain improvement after SNRB and functional outcome was identified. Conclusion. The degree of improvement in symptoms 6 hours after SNRB can predict the degree of improvement in LLRP at 12 months after surgery. However, symptomatic improvement after SNRB does not predict postoperative functional outcome or quality of life. | Ko, Sangbong; Jun, ChungMu; Min, Woo-Kie; Son, Eunseok; Lee, Sukjoong; Lee, Gun Woo; Yoo, Hyunseung | Daegu Catholic Univ, Daegu Catholic Univ Hosp, Sch Med, Dept Orthopaed Surg, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Orthopaed Surg, Daegu, South Korea; Keimyung Univ, Sch Med, Dept Orthopaed Surg, Dongsan Med Ctr, Daegu, South Korea; Yeungnam Univ, Yeungnam Univ Med Cen ter, Dept Orthopaed Surg, Coll Med, Daegu, South Korea; Daegu Fatima Hosp, Dept Orthopaed Surg, Daegu, South Korea | 36741770100; 57210019245; 8548041000; 38663387700; 57078230800; 55599978600; 57217302438 | bong@cu.ac.kr; | SPINE | SPINE | 0362-2436 | 1528-1159 | 47 | 9 | SCIE | CLINICAL NEUROLOGY;ORTHOPEDICS | 2022 | 3 | 25.0 | 0.69 | 2025-06-25 | 7 | 6 | nerve block; neuralgia; outcomes | DISC HERNIATION; INJECTION; SCIATICA | nerve block; neuralgia; outcomes | Disability Evaluation; Humans; Lumbar Vertebrae; Pain, Postoperative; Quality of Life; Retrospective Studies; Spinal Stenosis; Treatment Outcome; bupivacaine; lidocaine; triamcinolone; adult; aged; Article; body weight; clinical outcome; controlled study; degenerative disease; facetectomy; female; fifth lumbar vertebra; fluoroscopy; follow up; fourth lumbar vertebra; functional status; human; laminotomy; leeds assessment of neuropathic symptom and sign; local anesthesia; lower leg; lumbar spinal stenosis; major clinical study; male; medical assessment; nerve block; neuralgia; neurologic examination; nuclear magnetic resonance imaging; Oswestry Disability Index; outpatient care; pain assessment; pain severity; postoperative analgesia; postoperative period; preoperative evaluation; quality of life; retrospective study; Roland Morris disability questionnaire; Short Form 36; spinal cord decompression; spine fusion; spine radiography; very elderly; visual analog scale; young adult; complication; disability; lumbar vertebra; postoperative pain; treatment outcome; vertebral canal stenosis | English | 2022 | 2022-05-01 | 10.1097/brs.0000000000004216 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Correlation between serum markers in the second trimester and preterm birth before 34 weeks in asymptomatic twin pregnancies | Objective To determine the correlation between the levels of serum markers in the second trimester and preterm birth before 34 weeks in asymptomatic twin pregnancies. Methods We conducted a retrospective review of the medical records of 102 asymptomatic twin pregnancies delivered at Chilgok Kyungpook National University Hospital between March 2014 and February 2020. Participants were divided into two groups, based on delivery before and after 34 weeks of gestation. Results of the quad test performed at 15-18 weeks and the complete blood count done at 24-28 weeks were compared. Results Preterm birth before 34 weeks of pregnancy was associated with higher levels of maternal alpha-fetoprotein (1.04 vs 0.98, multiple of median [MoM], P = 0.006), human chorionic gonadotropin (1.76 vs 1.31, MoM, P = 0.000), and inhibin A (1.78 vs 1.04, MoM, P = 0.000). Positive correlations were observed between gestational age at delivery and white blood cell (WBC) markers. Women with preterm delivery had decreased WBC counts (8180 vs 9405 x 10(3)/mu l, P = 0.019) and neutrophil:lymphocyte ratios (3.85 vs 4.92, P = 0.001). Conclusion Serum marker levels in the second trimester can be indicators of preterm delivery before 34 weeks in asymptomatic twin pregnancies. | Kim, Mi Ju; Kim, Hyun Mi; Cha, Hyun Hwa; Kim, Jong In; Seong, Won Joon | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Obstet & Gynecol, Daegu 41944, South Korea | Kim, Mi Ju/HGU-8470-2022; Kim, Jong/K-3445-2013 | 55908927600; 57219838830; 37033517800; 57221979059; 26656946000 | ties1004@naver.com; | INTERNATIONAL JOURNAL OF GYNECOLOGY & OBSTETRICS | INT J GYNECOL OBSTET | 0020-7292 | 1879-3479 | 156 | 2 | SCIE | OBSTETRICS & GYNECOLOGY | 2022 | 3.8 | 25.3 | 0.17 | 2025-06-25 | 2 | 1 | human chorionic gonadotropin; inhibin A; neutrophil-lymphocyte ratio; preterm birth; twin; alpha-fetoprotein | LYMPHOCYTE RATIO; NEUTROPHIL; PREDICTION; RISK | Biomarkers; Female; Humans; Infant, Newborn; Pregnancy; Pregnancy Trimester, Second; Pregnancy, Twin; Premature Birth; Retrospective Studies; alpha fetoprotein; biological marker; chorionic gonadotropin; inhibin A; biological marker; adult; Article; controlled study; female; gestational age; human; leukocyte count; major clinical study; medical record review; neutrophil lymphocyte ratio; obstetric delivery; premature labor; protein blood level; retrospective study; second trimester pregnancy; twin pregnancy; newborn; pregnancy; prematurity; second trimester pregnancy; twin pregnancy | English | 2022 | 2022-02 | 10.1002/ijgo.13822 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Cyclic parallel structure Jacobi operator for real hypersurfaces in complex two-plane Grassmannians | In this paper, from the property of Killing for structure Jacobi tensor R-xi, we introduce a new notion of cyclic parallelism of structure Jacobi operator R-xi on real hypersurfaces in the complex two-plane Grassmannians. By virtue of geodesic curves, we can give the equivalent relation between cyclic parallelism of R-xi and Killing property of R-xi. Then, we classify all Hopf real hypersurfaces with cyclic parallel structure Jacobi operator in complex two-plane Grassmannians. | Lee, Hyunjin; Suh, Young Jin; Woo, Changhwa | Kyungpook Natl Univ, Res Inst Real & Complex Manifolds RIRCM, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Appl Math, Busan 48513, South Korea | 55706812200; 7202260479; 56075678000 | lhjibis@hanmail.net;yjsuh@knu.ac.kr;legalgwch@pknu.ac.kr; | PROCEEDINGS OF THE ROYAL SOCIETY OF EDINBURGH SECTION A-MATHEMATICS | P ROY SOC EDINB A | 0308-2105 | 1473-7124 | 152 | 4 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2022 | 1.3 | 25.3 | 0.49 | 2025-06-25 | 2 | 2 | Hopf real hypersurface; complex two-plane Grassmannians; (quadratic) Killing tensor; cyclic parallelism; structure Jacobi operator | ISOMETRIC REEB FLOW; RICCI TENSOR; LIE DERIVATIVES | (quadratic) Killing tensor; complex two-plane Grassmannians; cyclic parallelism; Hopf real hypersurface; structure Jacobi operator | English | 2022 | 2022-08 | 10.1017/prm.2021.42 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Exploiting Read Current Noise of TiOx Resistive Memory by Controlling Forming Conditions for Probabilistic Neural Network Hardware | Conductance variations of resistive random-access memory (RRAM) are significant challenges that hinder the accurate inference of neural network (NN) hardware. In this study, we exploit the read noise of the RRAM as an active computational enabler for implementing probabilistic NN. As electrical characteristics of RRAM are directly related to the properties of conductive filament (CF), we statistically explore read current of TiOx-based RRAM with different forming conditions and explain the results by linking the CF model. In addition, an array mapping scheme to transfer weights to one transistor-one RRAM (1T1R) array is experimentally demonstrated. Through NN simulations, we verify that the probabilistic NN shows promising results on nonlinear classification problem avoiding overconfidence compared with deterministic NN. | Choi, Wooseok; Ji, Wonjae; Heo, Seongjae; Lee, Donguk; Noh, Kyungmi; Lee, Chuljun; Woo, Jiyong; Kim, Seyoung; Hwang, Hyunsang | Pohang Univ Sci & Technol, Ctr Single Atom Based Semicond Device, Pohang 37673, South Korea; Pohang Univ Sci & Technol, Dept Mat Sci & Engn, Pohang 37673, South Korea; Kyungpook Natl Univ, Dept Elect Engn, Daegu 41566, South Korea | Choi, Wooseok/AGO-4845-2022; Kim, Sangbum/B-7069-2016; Heo, Seongjae/LVS-1818-2024 | 57223379030; 57419287700; 57218697128; 57212667343; 57326724000; 57201197166; 53985749100; 57211871375; 7403258319 | hwanghs@postech.ac.kr; | IEEE ELECTRON DEVICE LETTERS | IEEE ELECTR DEVICE L | 0741-3106 | 1558-0563 | 43 | 9 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2022 | 4.9 | 25.3 | 0.24 | 2025-06-25 | 3 | 3 | Artificial neural networks; Temperature measurement; Probabilistic logic; Neural networks; Temperature distribution; Standards; Switches; Bayesian neural networks; filamentary RRAM; neuromorphic; probabilistic computing; synaptic device | RRAM; LEVEL | Bayesian neural networks; filamentary RRAM; neuromorphic; probabilistic computing; synaptic device | Bayesian networks; Computation theory; Knowledge based systems; Probability distributions; RRAM; Temperature measurement; Bayesian neural networks; Filamentary resistive random-access memory; Forming conditions; Neural-networks; Neuromorphic; Probabilistic computing; Probabilistics; Random access memory; Read current; Synaptic device; Neural networks | English | 2022 | 2022-09 | 10.1109/led.2022.3192262 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
