| ○ | ○ | Article | Simulation of the Number of Strawberry Transplants Produced by an Autotrophic Transplant Production Method in a Plant Factory with Artificial Lighting | To verify the productivity of the autotrophic transplant production method (ATPM), a novel propagation method in a plant factory with artificial lighting for transplant production (T-PFAL), strawberry transplants were produced by the ATPM for 365 days. A total of 3497 transplants were produced by the ATPM over 365 days with nine propagules in a cultivation area of 3.6 m(2) in the T-PFAL. When the simulated results were fit with the measured results, the propagation cycle timescales from planting propagules to producing the first, second, and third runner plants were 15, 27, and 43 days, respectively. The cumulative number of transplants (CNT) produced from 5, 10, and 20 initial propagules in a cultivation area of 36 m(2) over 365 days was simulated by the verified program along with the propagation cycles, and these values were 27,970, 30,010, and 31,900, respectively. The simulated CNTs from nine initial propagules in 18 and 72 m(2) over 365 days were 15,950 and 55,940, respectively. These results indicate that the ATPM is an appropriate propagation method to produce transplants rapidly in a T-PFAL, especially when the number of propagules or propagules is limited. | Park, Seon Woo; Kim, Sung Kyeom; Kwack, Yurina; Chun, Changhoo | Farm8 Co Ltd, Indoor Farm & Protected Hort Lab, Pyeongtaek 17706, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Yonam Coll, Div Smart Hort, Cheonan 31005, South Korea; Seoul Natl Univ, Dept Plant Sci, Seoul 08826, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, Seoul 08826, South Korea | ; Kim, Sung Kyeom/AAD-9230-2019; Chun, Changhoo/B-7379-2012 | 56818089300; 50262290200; 18436934700; 7101953896 | psw@farm8.co.kr;skkim76@knu.ac.kr;greenrina@yonam.ac.kr;changhoo@snu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 6 | 4 | SCIE | HORTICULTURE | 2020 | 2.331 | 20.3 | 0.91 | 2025-06-25 | 9 | 11 | Fragaria × ananassa; propagation method; vegetative propagation; vertical farm | PROPAGATION | Fragaria × ananassa; Propagation method; Vegetative propagation; Vertical farm | English | 2020 | 2020-12 | 10.3390/horticulturae6040063 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structural or population dynamics: what is revealed by the time-resolved photoelectron spectroscopy of 1,3-cyclohexadiene? A study with an ensemble density functional theory method | Time-resolved photoelectron spectra during the photochemical ring-opening reaction of 1,3-cyclohexadiene (CHD) are modeled by an ensemble density functional theory (eDFT) method. The computational methodology employed in this work is capable of correctly describing the multi-reference effects arising in the ground and excited electronic states of molecules, which is important for the correct description of the ring-opening reaction of CHD. The geometries of molecular species along the non-adiabatic molecular dynamics (NAMD) trajectories reported in a previous study of the CHD photochemical ring-opening were used in this work to calculate the ionization energies and the respective Dyson orbitals for all possible ionization channels. The obtained theoretical time-resolved spectra display decay characteristics in a reasonable agreement with the experimental observations;i.e., the decay (and rise) of the most mechanistically significant signals occurs on the timescale of 100-150 fs. This is very different from the excited state population decay characteristics (tau(S1)= 234 +/- 8 fs) obtained in the previous NAMD study. The difference between the population decay and the decay of the photoelectron signal intensity is traced back to the geometric transformation that the molecule undergoes during the photoreaction. This demonstrates the importance of including the geometric information in interpretation of the experimental observations. | Filatov, Michael; Lee, Seunghoon; Nakata, Hiroya; Choi, Cheol Ho | Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea; CALTECH, Div Chem & Chem Engn, Pasadena, CA 91125 USA; Kyocera, R&D Ctr Kagoshima, 1-4 Kokubu Yamashita Cho, Kirishima, Kagoshima 8994312, Japan | Choi, Cheol Ho/AAA-4705-2020; Nakata, Hiroya/V-3205-2018; Lee, Seunghoon/AAB-4846-2021 | 7005134246; 57194591254; 55305767500; 7402958948 | mike.filatov@gmail.com;cheolho.choi@gmail.com; | PHYSICAL CHEMISTRY CHEMICAL PHYSICS | PHYS CHEM CHEM PHYS | 1463-9076 | 1463-9084 | 22 | 31 | SCIE | CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2020 | 3.676 | 20.3 | 0.67 | 2025-06-25 | 10 | 10 | IONIZATION-POTENTIALS; MOLECULAR-DYNAMICS; KOOPMANS THEOREM; QUANTUM DYNAMICS; CYCLOHEXADIENE; MATRICES; PRODUCT; STATE | Computation theory; Decay (organic); Electronic states; Excited states; Geometry; Ionization; Mathematical transformations; Molecular dynamics; Molecules; Photoelectron spectroscopy; Photoelectrons; Photons; Reaction kinetics; Computational methodology; Decay characteristics; Density functional theory methods; Excited electronic state; Geometric transformations; Nonadiabatic molecular dynamics; Photoelectron spectrum; Time-resolved photoelectron spectroscopy; Density functional theory | English | 2020 | 2020-08-21 | 10.1039/d0cp02963g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structural stability of single-layer PdSe2 with pentagonal puckered morphology and its nanotubes | Two-dimensional (2D) materials have gained a lot of attention being a new class of materials with unique properties that could influence future technologies. Concomitant computational design and discovery of new two-dimensional materials have therefore become a significant part of modern materials research. The stability of these predicted materials has emerged as the main issue due to drawbacks of the periodic boundary condition approximation that allow one to pass common criteria of stability. Here, based on first-principle calculations, we demonstrate structural stability and instability of several recently proposed 2D materials with pentagonal morphology including the experimentally exfoliated single-layer PdSe2. It is found that an appropriate orientation of the central Pd sublattice with respect to Se-2 dimers effectively compensates all mechanical stress and preserves the planar structure of the PdSe2 nanoclusters, while the flakes of all other materials having pentagonal morphology exhibit non-zero curvature induced by excessive interatomic forces. The relative energies of the PdSe2 monolayer and nanotubes per formula unit also confirm that the planar monolayer is a global energy minimum. Like the monolayer, (n,0) PdSe2 tubes are indirect band gap semiconductors with similar band gaps, while (n,n) tubes reveal indirect-direct band gap transitions following the increase of the tube diameter. Small strain energies of large diameter tubes propose their possible experimental realization for various optoelectronic applications. | Kuklin, Artem, V; Agren, Hans; Avramov, Pavel, V | Siberian Fed Univ, Dept Sci & Innovat, 79 Svabodny Pr, Krasnoyarsk 660041, Russia; KTH Royal Inst Technol, Sch Engn Sci Chem Biotechnol & Hlth, Div Theoret Chem & Biol, S-10691 Stockholm, Sweden; Fed Siberian Res Clin Ctr FMBA Russia, Krasnoyarsk 660037, Russia; Henan Univ, Coll Chem & Chem Engn, Kaifeng 475004, Henan, Peoples R China; Kyungpook Natl Univ, Coll Nat Sci, Dept Chem, 80 Daehakro, Daegu 41566, South Korea | Agren, Hans/H-7715-2016; Kuklin, Artem/A-9007-2014 | 56035188600; 56109615300; 7004322420 | artem.icm@gmail.com; | PHYSICAL CHEMISTRY CHEMICAL PHYSICS | PHYS CHEM CHEM PHYS | 1463-9076 | 1463-9084 | 22 | 16 | SCIE | CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2020 | 3.676 | 20.3 | 1.71 | 2025-06-25 | 31 | 31 | ELECTRONIC-PROPERTIES; GRAPHENE; CRYSTALLINE; MONOLAYER; STRAIN | Energy gap; Monolayers; Nanotubes; Stability criteria; Experimental realizations; First principle calculations; Global energy minima; Optoelectronic applications; Periodic boundary conditions; Structural stabilities; Two Dimensional (2 D); Two-dimensional materials; Morphology | English | 2020 | 2020-04-28 | 10.1039/d0cp00979b | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Prospective Cohort Study of Durations of Staphylococcus aureus Bacteremia According to Different Phenotypes and a New Concept of Persistent Bacteremia | The purpose of this study was to describe and compare the duration of Staphylococcus aureus bacteremia (SAB) according to methicillin resistance and the primary foci of infection. We also aimed to newly define persistent SAB considering these results. Nonduplicated episodes of SAB in patients aged >= 15 years from 14 hospitals in the Republic of Korea were analyzed between January 2009 and February 2018. The duration of SAB was defined as the number of days from the time of administration of an antibiotic to which the isolate was susceptible after the onset of SAB to the last day of a positive blood culture for S. aureus. SAB durations were described and compared based on methicillin resistance and the primary foci of infection. Cases in the top quartile for the duration of bacteremia in the respective clinical context were classified as newly defined persistent SAB, and its association with in-hospital mortality was evaluated. A total of 1,917 cases were analyzed. The duration of SAB was longer in patients with methicillin-resistant SAB (MRSAB; n = 995) than in patients with methicillin-susceptible SAB (MSSAB; n = 922) (median duration, 1 day [interquartile range, 1 to 3 days] for MSSAB and 1 day [interquartile range, 0 to 5 days] for MRSAB; P < 0.001). The duration of bacteremia was longer in patients with endocarditis and bone and joint, endovascular, and surgical site infections and was shorter in patients with skin and soft tissue infections. Newly defined persistent SAB was independently associated with in-hospital mortality (adjusted odds ratio, 1.97; 95% confidence interval, 1.54 to 2.53; P < 0.001). The durations of SAB were dependent on methicillin resistance and the primary foci of infection, and considering these contexts, persistent SAB was significantly associated with in-hospital mortality. | Kang, Chang Kyung; Song, Kyoung-Ho; Kim, Seong Eun; Kim, Eu Suk; Park, Wan Beom; Park, Kyung-Hwa; Chun, Shin Hye; Lee, Shinwon; Cho, Chong Rae; Kang, Seung Ji; Oh, Myoung-don; Kim, Yeon-Sook; Lee, Sun Hee; Kwak, Yee Gyung; Jang, Hee-Chang; Kim, Chung-Jong; Kim, Young Keun; Bang, Ji-Hwan; Kiem, Sungmin; Kwon, Ki Tae; Jung, Younghee; Kang, Yu Min; Jung, Sook-In; Kim, Hong Bin; Kim, Nam-Joong; Choe, Pyoeng Gyun; Kim, Taek Soo; Choi, Su Jin; Park, Kyoung Un; Choi, Yun Jung; Kwon, Kyoung Mi; Park, Jung In; Choi, Su-Mi; Yun, Seon Jin; Yi, Jongyoun; Park, Sohee; Hwang, Hyeon-jeong; Lee, Youngsoon; Choi, Hee Kyoung; Han, Myung Sook; Park, Sang Won; Kim, Dong-Kie; Song, Sae-Am; Kang, Min Ji; Shin, Jae Gyun; Kim, Hye-In; Shin, Seung Min | Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Coll Med, Seongnam, South Korea; Chonnam Natl Univ Hosp, Gwangju, South Korea; Chungnam Natl Univ Hosp, Daejon, South Korea; Pusan Natl Univ Hosp, Busan, South Korea; Inje Univ, Ilsan Paik Hosp, Goyang, South Korea; Chonnam Natl Univ, Hwasun Hosp, Hwasun, South Korea; Ehwa Womans Univ Hosp, Seoul, South Korea; Yonsei Univ, Wonju Severance Christian Hosp, Wonju, South Korea; Seoul Metropolitan Boramae Hosp, Seoul, South Korea; Inje Univ, Haeundae Paik Hosp, Busan, South Korea; Kyungpook Natl Univ, Dept Internal Med, Sch Med, Daegu, South Korea; Sacred Heart Hosp, Hallym Univ, Anyang, South Korea; Kangwon Natl Univ Hosp, Chunchon, South Korea; Seoul Natl Univ Hosp, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Seoul, South Korea; Chungnam Natl Univ Hosp, Daejeon, South Korea; Daegu Fatima Hosp, Daegu, South Korea | Park, Wan Beom/GLU-9886-2022; Kim, Young/H-4235-2013; Kim, Eu/J-5424-2012; Hwang, Soyoon/HHM-5762-2022; Park, Sang-Won/M-6366-2017; Park, Kyoung Un/J-5473-2012; Kim, Taek-Soo/C-1843-2011; LEE, SUN HEE/AAB-5714-2022; JUNG, SOOK IN/AGO-2862-2022; Kim, Sun/G-3451-2013; Kim, Nam-Joong/J-2735-2012; Kim, Seung/N-5248-2019; Kim, Hye-Ryoung/GPG-1346-2022; Kim, Ik-Sang/J-5425-2012; bu, ji/JUU-6900-2023; Kim, Hee/AAU-6368-2021; Kim, Hong Bin/J-5452-2012 | 55808491400; 23398486700; 57226683401; 22938086900; 7402229219; 57219637574; 57212539590; 24479446100; 57204358301; 37072777000; 7201600302; 57208777401; 57202327364; 7103120454; 7202135138; 45361165100; 35322538300; 15070169400; 6603471324; 9733850500; 57204538177; 55267459000; 7403676835; 35307429400 | sijung@chonnam.ac.kr;hbkimmd@snu.ac.kr; | ANTIMICROBIAL AGENTS AND CHEMOTHERAPY | ANTIMICROB AGENTS CH | 0066-4804 | 1098-6596 | 64 | 1 | SCIE | MICROBIOLOGY;PHARMACOLOGY & PHARMACY | 2020 | 5.191 | 20.5 | 0.26 | 2025-06-25 | 2 | 4 | Staphylococcus aureus; bacteremia; duration; methicillin resistance; primary foci of infection | CLINICAL-OUTCOMES; AGR DYSFUNCTION; MULTICENTER; INFECTIONS; PREDICTORS; RESISTANCE | Anti-Bacterial Agents; Bacteremia; Humans; Methicillin Resistance; Methicillin-Resistant Staphylococcus aureus; Phenotype; Prospective Studies; Republic of Korea; Risk Factors; Staphylococcal Infections; Staphylococcus aureus; antibiotic agent; beta lactam antibiotic; cephalosporin derivative; linezolid; nafcillin; teicoplanin; vancomycin; antiinfective agent; adult; antibiotic therapy; Article; bacterial endocarditis; blood culture; bone infection; catheter infection; catheter removal; Charlson Comorbidity Index; cohort analysis; disease duration; female; hospital discharge; hospital infection; hospital mortality; human; infectious arthritis; major clinical study; male; methicillin resistance; methicillin resistant Staphylococcus aureus; methicillin susceptible Staphylococcus aureus; middle aged; multicenter study; nonhuman; pneumonia; priority journal; prospective study; septic shock; Sequential Organ Failure Assessment Score; soft tissue infection; South Korea; staphylococcal bacteremia; staphylococcal skin infection; surgical infection; bacteremia; drug effect; microbiology; pathogenicity; phenotype; risk factor; Staphylococcus aureus; Staphylococcus infection | English | 2020 | 2020-01 | 10.1128/aac.01656-19 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Advancement of Mechanical Properties of Nickel-Titanium Rotary Endodontic Instruments by Spring Machining on the File Shaft | Nickel-titanium (NiTi) endodontic rotary instruments are used extensively in root canal procedures by both general dentists and specialists. However, their vulnerability to fracture is the major reason for clinicians' concern regarding their use. The objective of this study was to investigate the potential effects of spring machining of the file shaft on the fatigue and torsional resistances of NiTi rotary instruments. Three types of NiTi rotary systems with (S) and without (NS) spring machining were used in this study (n = 15 each): a spring file (SPR; #25/.06, SPR-S, SPR-NS), a ProTaper Next X2 (PTN; #25/variable taper, PTN-S, PTN-NS), and a ProTaper Gold F2 (PTG; #25/variable taper, PTG-S, PTG-NS). Spring machining was adjusted on the 6 mm of each file system's shaft via a laser cutting process. The number of rotation cycles until fracture (i.e., cyclic fatigue resistance), ultimate torsional strength, the distortion angle, and the toughness of each subgroup were estimated with specially designed devices. The results were analyzed using a paired t-test at a significance level of 95%. NiTi rotary instruments with spring machining exhibited a higher cyclic fatigue resistance than instruments without spring machining. The groups with spring machining exhibited a higher toughness and larger distortion angle than the groups without it (p < 0.05). In conclusion, spring machining on the shank of NiTi instruments may provide a stress-bearing area and attenuate the torsional and cyclic fatigue of NiTi rotary instruments. | Ahn, Sangmi; Ha, Jung-Hong; Kwak, Sang Won; Kim, Hyeon-Cheol | Pusan Natl Univ, Dent & Life Sci Inst, Dent Res Inst, Dept Conservat Dent,Sch Dent, Yangsan 50612, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, Daegu 41940, South Korea | ; Kim, Hyeon/AAQ-9057-2021 | 57219987873; 55549831900; 54787794900; 35746710200 | smahn4009@gmail.com;endoking@knu.ac.kr;endokwak@pusan.ac.kr;golddent@pusan.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 22 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.16 | 2025-06-25 | 4 | 4 | fatigue; fracture; resistance; spring; structure; torsion fracture | CYCLIC FATIGUE RESISTANCE; PROTAPER GOLD; PHASE-TRANSFORMATION; CONTROLLED MEMORY; UNIVERSAL; STIFFNESS | Fatigue; Fracture; Resistance; Spring; Structure; Torsion fracture | Binary alloys; Mechanical properties; Nickel; Springs (components); Titanium; Cyclic fatigue; Laser cutting process; Nickel titanium; Potential effects; Significance levels; Specially designed devices; Torsional resistance; Ultimate torsional strength; Fatigue of materials | English | 2020 | 2020-11 | 10.3390/ma13225246 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Aggregate Roundness Classification Using a Wire Mesh Method | Herein, we suggest a wire mesh method to classify the particle shape of large amounts of aggregate. This method is controlled by the tilting angle and opening size of the wire mesh. The more rounded the aggregate particles, the more they roll on the tilted wire mesh. Three different sizes of aggregate: 11-15, 17-32, and 33-51 mm were used for assessing their roundness after classification using the sphericity index into rounded, sub-rounded/sub-angular, and angular. The aggregate particles with different sphericities were colored differently and then used for classification via the wire mesh method. The opening sizes of the wire mesh were 6, 11, and 17 mm and its frame was 0.5 m wide and 1.8 m long. The ratio of aggregate size to mesh-opening size was between 0.6 and 8.5. The wire mesh was inclined at various angles of 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees to evaluate the rolling degree of the aggregates. The aggregates were rolled and remained on the wire mesh between 0.0-0.6, 0.6-1.2, and 1.2-1.8 m depending on their sphericity. A tilting angle of 25 degrees was the most suitable angle for classifying aggregate size ranging from 11-15 mm, while the most suitable angle for aggregate sizes of 17-32 and 33-51 mm was 20 degrees. The best ratio for the average aggregate size to mesh-opening size for aggregate roundness classification was 2. | Park, Sung-Sik; Lee, Jung-Shin; Lee, Dong-Eun | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy, 80 Daehakro, Daegu 41566, South Korea | Lee, Jung Bok/HHZ-3200-2022 | 36241850300; 57210867035; 56605563300 | sungpark@knu.ac.kr;jhjs14@knu.ac.kr;dolee@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 17 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.14 | 2025-06-25 | 2 | 3 | aggregate; classification; wire mesh; roundness; tilting angle; opening size | SHAPE; VOLUME | Aggregate; Classification; Opening size; Roundness; Tilting angle; Wire mesh | Mesh generation; Wire; Aggregate particles; Aggregate size; Different sizes; Large amounts; Opening sizes; Particle shape; Sphericity indices; Suitable angles; Aggregates | English | 2020 | 2020-09 | 10.3390/ma13173682 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Application of a Novel CVD TiN Coating on a Biomedical Co-Cr Alloy: An Evaluation of Coating Layer and Substrate Characteristics | Titanium nitride (TiN) was deposited on the surface of a cobalt-chromium (Co-Cr) alloy by a hot-wall type chemical vapor deposition (CVD) reactor at 850 degrees C, and the coating characteristics were compared with those of a physical vapor deposition (PVD) TiN coating deposited on the same alloy at 450 degrees C. Neither coating showed any reactions at the interface. The face-centered cubic (fcc) structure of the alloy was changed into a hexagonal close-packed (hcp) phase, and recrystallization occurred over at 10 mu m of depth from the surface after CVD coating. Characteristic precipitates were also generated incrementally depending on the depth, unlike the precipitates in the matrix of the as-cast alloy. On the other hand, the microstructure and phase of the PVD-coated alloy did not change. Depth-dependent nano-hardness measurements showed a greater increase in hardness in the recrystallization zone of the CVD-coated alloy than in the bulk center of the alloy. The CVD coating showed superior adhesion to the PVD coating in the progressive scratch test. The as-cast, PVD-coated, and CVD-coated alloys all showed negative cytotoxicity. Within the limitations of this study, CVD TiN coating to biomedical Co-Cr alloy may be considered a promising alternative to PVD technique. | Song, Si Hoon; Min, Bong Ki; Hong, Min-Ho; Kwon, Tae-Yub | Kyungpook Natl Univ, Grad Sch, Dept Med & Biol Engn, Daegu 41940, South Korea; Yeungnam Univ, Ctr Res Facil, Gyongsan 38541, South Korea; Catholic Univ Pusan, Dept Dent Lab Sci, Coll Hlth Sci, Busan 46252, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Biomat Res & Dev, Daegu 41940, South Korea | 57203824761; 57211058922; 57192705343; 7202206084 | song@taegutec.co.kr;bkmin@ynu.ac.kr;mhhong@cup.ac.kr;tykwon@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 5 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.77 | 2025-06-25 | 21 | 21 | cobalt-chromium alloy; titanium nitride; physical vapor deposition; chemical vapor deposition; microstructure | TITANIUM NITRIDE; MICROSTRUCTURE; DEPOSITION; RELEASE; COCRMO | Chemical vapor deposition; Cobalt-chromium alloy; Microstructure; Physical vapor deposition; Titanium nitride | Binary alloys; Chemical vapor deposition; Coatings; Cobalt alloys; Hardness; Microstructure; Physical vapor deposition; Recrystallization (metallurgy); Titanium alloys; Titanium nitride; As cast alloy; Chemical vapor deposition reactors; Coating characteristics; Cobalt-chromium alloys; Depth dependents; Face centered cubic structure; Hexagonal close packed; Substrate characteristics; Chromium alloys | English | 2020 | 2020-03 | 10.3390/ma13051145 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Comparing Rubber Bearings and Eradi-Quake System for Seismic Isolation of Bridges | Seismic isolation systems have been used worldwide in bridge structures to reduce vibration and avoid collapse. The seismic isolator, damper, and Shock Transmission Unit (SUT) are generally adopted in the seismic design of bridges to improve their seismic safety with economic efficiency. There are several seismic isolation systems, such as Natural Rubber Bearing (NRB), Lead Rubber Bearing (LRB), and the Eradi-Quake System (EQS). EQS as a new technology is expected to effectively reduce both seismic force and displacement, but there is still some need to verify whether it might provide an economical and practical strategy for a bridge isolation system. Moreover, it is important to guarantee consistent performance of the isolators by quality control. A comparative evaluation of the basic properties of the available seismic isolators is thus necessary to achieve a balance between cost-effectiveness and the desired performance of the bridge subjected to extreme loading. Accordingly, in this study, the seismic response characteristics of the seismic isolation systems for bridges were investigated by conducting compressive test and compressive-shear test on NRB, LRB, and EQS. | Cho, Chang Beck; Kim, Young Jin; Chin, Won Jong; Lee, Jin-Young | Korea Inst Civil Engn & Bldg Technol, Dept Infrastruct Safety Res, Goyang 10223, South Korea; Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, Daegu 41566, South Korea | 36559024900; 55578805600; 23484628000; 57203144661 | cbcho@kict.re.kr;yjkim@kict.re.kr;wjchin@kict.re.kr;jinyounglee@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 22 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.35 | 2025-06-25 | 12 | 11 | seismic isolator; seismic isolation of bridges; natural rubber bearing; lead rubber bearing; Eradi-Quake System (EQS); energy dissipated per cycle (EDC) | Energy dissipated per cycle (EDC); Eradi-Quake System (EQS); Lead rubber bearing; Natural rubber bearing; Seismic isolation of bridges; Seismic isolator | Bearings (structural); Bridges; Cost effectiveness; Earthquakes; Nonmetallic bearings; Quality control; Rubber; Bridge isolations; Comparative evaluations; Consistent performance; Economic efficiency; Lead rubber bearing; Seismic isolation systems; Seismic response characteristics; Shock transmission; Seismic design | English | 2020 | 2020-11 | 10.3390/ma13225247 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Cost-Effective Production of TiO2 with 90-Fold Enhanced Photocatalytic Activity Via Facile Sequential Calcination and Ball Milling Post-Treatment Strategy | Titanium dioxide (TiO2), the golden standard among the photocatalysts, exhibits a varying level of photocatalytic activities (PCA) amongst the synthetically prepared and commercially available products. For commercial applications, superior photoactivity and cost-effectiveness are the two main factors to be reckoned with. This study presents the development of simple, cost-effective post-treatment processes for a less costly TiO2 to significantly enhance the PCA to the level of expensive commercial TiO2 having demonstrated superior photoactivities. We have utilized sequential calcination and ball milling (BM) post-treatment processes on a less-costlier KA100 TiO2 and demonstrated multi-fold (nearly 90 times) enhancement in PCA. The post-treated KA100 samples along with reference commercial samples (P25, NP400, and ST01) were well-characterized by appropriate instrumentation and evaluated for the PCA considering acetaldehyde photodegradation as the model reaction. Lattice parameters, phase composition, crystallite size, surface functionalities, titanium, and oxygen electronic environments were evaluated. Among post-treated KA100, the sample that is subjected to sequential 700 degrees C calcination and BM (KA7-BM) processes exhibited 90-fold PCA enhancement over pristine KA100 and the PCA-like commercial NP400 (pure anatase-based TiO2). Based on our results, we attribute the superior PCA for KA7-BM due to the smaller crystallite size, the co-existence of mixed anatase-srilankite-rutile phases, and the consequent multiphase heterojunction formation, higher surface area, lattice disorder/strain generation, and surface oxygen environment. The present work demonstrates a feasible potential for the developed post-treatment strategy towards commercial prospects. | Gopalan, Anantha-Iyengar; Lee, Jun-Cheol; Saianand, Gopalan; Lee, Kwang-Pill; Chun, Woo-Young; Hou, Yao-long; Kannan, Venkatramanan; Park, Sung-Sik; Kim, Wha-Jung | Kyungpook Natl Univ, Sch Architecture & Civil Engn, Daegyeong Reg Infrastruct Technol Dev Ctr, Daegu 41566, South Korea; Seowon Univ, Dept Architecture, Cheongju 28674, South Korea; Univ Newcastle, Global Ctr Environm Remediat GCER, Fac Sci, Callaghan, NSW 2308, Australia; Korea Conform Labs, Real Scale Fire Testing, Res Ctr, 33-72,Eonjang 1 Gil, Samcheok Si 25913, Gangwon Do, South Korea; Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; SCSVMV Deemed Univ, Dept Phys, Kanchipuram 631561, India | ; kannan, venkatramanan/N-4628-2016; Gopalan, Saianand/J-6000-2019; Hou, Yaolong/KRP-4300-2024 | 57191999779; 55694062800; 38362265400; 8382891300; 59822273700; 57210563078; 57218952492; 36241850300; 57203533494 | algopal99@gmail.com;uggenius@hanmail.net;SaiAnand.Gopalan@newcastle.edu.au;kplee@knu.ac.kr;cwy@kcl.re.kr;hylmm8988@hotmail.com;kv@kanchiuniv.ac.in;sungpark@knu.ac.kr;kimwj@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 22 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.43 | 2025-06-25 | 8 | 8 | titanium dioxide; low-cost; calcination; ball milling; post-treatment | X-RAY-DIFFRACTION; SCHERRER EQUATION; PHASE TIO2; NANOPARTICLES; ANATASE; RUTILE; REFINEMENT; OXIDATION; DESIGN; POWDER | Ball milling; Calcination; Low-cost; Post-treatment; Titanium dioxide | Ball milling; Calcination; Cost effectiveness; Crystallite size; Heterojunctions; Milling (machining); Oxide minerals; Oxygen; Photocatalytic activity; Titanium dioxide; Commercial applications; Commercial prospect; Cost-effective production; Electronic environments; Lattice disorders; Post-treatment process; Surface functionalities; Titanium dioxides (TiO2); Costs | English | 2020 | 2020-11 | 10.3390/ma13225072 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dentin Bonding of TheraCal LC Calcium Silicate Containing an Acidic Monomer: An In Vitro Study | The purpose of this study was to evaluate whether the incorporation of an acidic monomer into the pulp-capping material TheraCal LC, which has a weak dentin bonding, increases the shear bond strength (SBS) to dentin. Di-2-hydroxyethyl methacryl hydrogenphosphate was incorporated into the material at 0.0 (TL0, control), 5.0 (TL5), and 10.0 (TL10) wt%. The water contact angle (CA) and mechanical properties for each material were also studied (n = 6). Debonding was performed at two different times (immediate and after 24 h) (n = 12). Hydroxyl and calcium ion releases in water at 37 degrees C were monitored up to 28 days (n = 6). The addition of the acidic monomer decreased the CAs (p < 0.001) and increased the flexural moduli (p < 0.001). The debonding time did not significantly affect the SBS values (p = 0.600). The TL10 group exhibited the highest SBS values, followed by the TL5 group. The TL10 group released significantly more calcium ions than the other two groups from 3 days (p < 0.05). The incorporation of the acidic monomer at 10.0 wt% into TheraCal LC enhanced bonding to dentin, while not negatively affecting the mechanical properties and ion-leaching capacity of the material. | Kim, Young Kyung; Hong, Mi-Hee; Kwon, Tae-Yub | Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Biomat Res & Dev, Daegu 41940, South Korea | 56017868900; 57190379016; 7202206084 | wisekim@knu.ac.kr;mhhong1208@knu.ac.kr;tykwon@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 2 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.38 | 2025-06-25 | 7 | 7 | calcium silicate; pulp capping; dentin bonding; acidic monomer | PERSPECTIVES; AGENTS; MTA | Acidic monomer; Calcium silicate; Dentin bonding; Pulp capping | Bond strength (materials); Contact angle; Debonding; Ions; Monomers; Silicates; Acidic monomers; Calcium ions; Dentin bonding; Flexural modulus; Hydrogen phosphates; Pulp capping; Shear bond strengths; Water contact angle; Calcium silicate | English | 2020 | 2020-01-02 | 10.3390/ma13020293 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Durability and Strength Characteristics of Casein-Cemented Sand with Slag | Casein is often used as an eco-friendly wood adhesive. In this study, we used casein for soil cementation by mixing it with Jumunjin sand, sodium hydroxide (SH), and calcium hydroxide (CH) as a standard casein formula. The modified casein binder with different proportions of SH and CH was applied to improve water resistance. Furthermore, a blast furnace slag (BFS) was additionally mixed and reacted with alkalinity of modified casein binder. Thus, three types (standard, modified, and modified + BFS, referred to as STD, MOD, and MBS, hereafter) of casein binders were tested for durability and strength of casein-cemented sand. A piezoelectric sensor was installed within each sample to determine the curing time of the casein-cemented samples. The samples were air-cured at room temperature for seven days and some were repeatedly immersed in water thrice. Unconfined compression and jar slake tests were carried out to evaluate the strength and durability of the casein-cemented sand. Also, the microstructure was analyzed using a scanning electron microscope (SEM). We observed variations of peak conductance and corresponding frequency converged as the curing time increased. It was most significant for the MBS samples, which developed strength early. The unconfined compressive strength (UCS) of the air-cured samples was higher than those repeatedly immersed in water due to wash-off of the casein binder. The UCS of the dry MBS sample was 9900 kPa while that of the immersed sample was 430 kPa, which gradually decreased to 60 kPa upon repeated immersion. The samples with STD and MOD had no resistance to durability and showed cracks on the surface, while the MBS sample exhibited significantly improved durability and no cracks. We found that the MBS binder had a positively significant effect on the durability and strength of casein-cemented sand. | Park, Sung-Sik; Woo, Seung-Wook; Jeong, Sueng-Won; Lee, Dong-Eun | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Daejeon 34132, South Korea; Kyungpook Natl Univ, Dept Architectural Engn, 80 Daehakro, Daegu 41566, South Korea | 36241850300; 57212917862; 35069425600; 56605563300 | sungpark@knu.ac.kr;geowsw@knu.ac.kr;swjeong@kigam.re.kr;dolee@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 14 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.5 | 2025-06-25 | 12 | 12 | durability; strength; casein; soil binder; blast furnace slag | BLAST-FURNACE SLAG; ACTIVATION; HYDRATION | Blast furnace slag; Casein; Durability; Soil binder; Strength | Adhesives; Binders; Blast furnaces; Casein; Compressive strength; Curing; Dairies; Hydrated lime; Lime; Sand; Scanning electron microscopy; Slags; Sodium hydroxide; Cemented sands; Different proportions; Piezoelectric sensors; Strength characteristics; Unconfined compression; Unconfined compressive strength; Water-resistances; Wood adhesives; Durability | English | 2020 | 2020-07 | 10.3390/ma13143182 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of Low-Pressure Plasma Treatment Parameters on Wrinkle Features | Wrinkles attract significant attention due to their ability to enhance the mechanical and optical characteristics of various optoelectronic devices. We report the effect of the plasma gas type, power, flow rate, and treatment time on the wrinkle features. When an optical adhesive was treated using a low-pressure plasma of oxygen, argon, and nitrogen, the oxygen and argon plasma generated wrinkles with the lowest and highest wavelengths, respectively. The increase in the power of the nitrogen and oxygen plasma increased the wavelengths and heights of the wrinkles; however, the increase in the power of the argon plasma increased the wavelengths and decreased the heights of the wrinkles. Argon molecules are heavier and smaller than nitrogen and oxygen molecules that have similar weights and sizes; moreover, the argon plasma comprises positive ions while the oxygen and nitrogen plasma comprise negative ions. This resulted in differences in the wrinkle features. It was concluded that a combination of different plasma gases could achieve exclusive control over either the wavelength or the height and allow a thorough analysis of the correlation between the wrinkle features and the characteristics of the electronic devices. | Gu, Bongjun; Ko, Dongwook; Jo, Sungjin; Hyun, Dong Choon; Oh, Hyeon-Ju; Kim, Jongbok | Kumoh Natl Inst Technol, Dept Mat Sci & Engn, Gumi 39177, Gyeongbuk, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, Gyeongbuk, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Kumoh Natl Inst Technol, Adv Mat Res Ctr, Gumi 39177, Gyeongbuk, South Korea | Oh, Hyeon-Ju/ABH-2809-2020 | 57193761401; 24479440600; 7101724027; 15834575400; 56362812200; 15762365000 | bgid90ga@gmail.com;duko1293@gmail.com;sungjin@knu.ac.kr;dong.hyun@knu.ac.kr;smju26@kumoh.ac.kr;jb1956k@gmail.com; | MATERIALS | MATERIALS | 1996-1944 | 13 | 17 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 0.22 | 2025-06-25 | 5 | 5 | wrinkles; physical structures; plasma treatment; stress relaxation | POLYMER | Physical structures; Plasma treatment; Stress relaxation; Wrinkles | Adhesives; Argon; Molecules; Negative ions; Optoelectronic devices; Oxygen; Plasma applications; Positive ions; Electronic device; Low pressure plasma; Low pressure plasma treatment; Optical adhesive; Optical characteristics; Oxygen and nitrogens; Oxygen molecule; Treatment time; Nitrogen plasma | English | 2020 | 2020-09 | 10.3390/ma13173852 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Phosphate-Based Inhibitor on Corrosion Kinetics and Mechanism for Formation of Passive Film onto the Steel Rebar in Chloride-Containing Pore Solution | In the present study, different contents, i.e., 1-3% of 0.5 M ammonium phosphate mono basic (APMB), were used as corrosion inhibitor to reduce the corrosion of steel rebar. Electrochemical impedance spectroscopy (EIS) results showed that up to 24 h of exposure, polarization resistance (R-p) and passive/oxide film resistance (R-o) gradually decreased in simulated concrete pore (SCP) + 3.5 wt.% NaCl solution owing to the reduction in pH of the solution. The steel rebar exposed in 2% inhibitor containing SCP + 3.5 wt.% NaCl solution exhibited 90% inhibition efficiency after 1 h of exposure. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy confirmed the formation of thermodynamically very stable and sparingly soluble goethite (alpha-FeOOH), maghemite (gamma-Fe2O3), and iron phosphate (FePO4) as passive/oxide film onto the steel rebar surface exposed to 2% inhibitor containing SCP + 3.5 wt.% NaCl solution. | Mandal, Soumen; Singh, Jitendra Kumar; Lee, Dong-Eun; Park, Taejoon | Kyungpook Natl Univ, Intelligent Construct Automat Ctr, 80 Daehak Ro, Daegu 41566, South Korea; Hanyang Univ, Dept Architectural Engn, Innovat Durable Bldg & Infrastruct Res Ctr, 1271 Sa3 Dong, Ansan 15588, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy, 1370 Sangyegk Dong, Daegu 702701, South Korea; Hanyang Univ, Dept Robot Engn, 55 Hanyangdaehak Ro, Ansan 15588, South Korea | ; Mandal, Soumen/AAB-3917-2021; Singh, Jitendra/AAU-6579-2021 | 57214752240; 57197846307; 56605563300; 55717001200 | sou.chm@gmail.com;jk200386@hanyang.ac.kr;dolee@knu.ac.kr;taejoon@hanyang.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 16 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 1.21 | 2025-06-25 | 33 | 36 | steel; concrete pore solution; corrosion; inhibitor; electrochemical impedance spectroscopy; Raman spectroscopy | SATURATED CA(OH)(2) SOLUTION; CARBON-STEEL; SIMULATED CONCRETE; REINFORCING STEEL; CALCIUM NITRITE; CONTAMINATED CONCRETE; WATER-VAPOR; BEHAVIOR; OXIDATION; IONS | Concrete pore solution; Corrosion; Electrochemical impedance spectroscopy; Inhibitor; Raman spectroscopy; Steel | Corrosion inhibitors; Electrochemical corrosion; Electrochemical impedance spectroscopy; Gamma rays; Hematite; Iron metallography; Nitrogen compounds; Rebar; Sodium chloride; Steel corrosion; X ray photoelectron spectroscopy; Ammonium phosphates; Corrosion kinetics; Corrosion of steel; Film resistance; Inhibition efficiency; Phosphate based inhibitors; Polarization resistances; Simulated concrete pore; Iron alloys | English | 2020 | 2020-08 | 10.3390/ma13163642 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Tooth Types on the Accuracy of Dental 3D Scanners: An In Vitro Study | The purpose of this study was to evaluate the accuracy of dental three-dimensional (3D) scanners according to the types of teeth. A computer-aided design (CAD) reference model (CRM) was obtained by scanning the reference typodont model using a high-precision industrial scanner (Solutionix C500, MEDIT). In addition, a CAD test model (CTM) was obtained using seven types of dental 3D scanners (desktop scanners (E1 and DOF Freedom HD) and intraoral scanners (CS3500, CS3600, Trios2, Trios3, and i500)). The 3D inspection software (Geomagic control X, 3DSystems) was used to segment the CRM according to the types of teeth and to superimpose the CTM based on the segmented teeth. The 3D accuracy of the scanner was then analyzed according to the types of teeth. One-way analysis of variance (ANOVA) was used to compare the differences according to the types of teeth in statistical analysis, and the Tukey HSD test was used for post hoc testing (alpha = 0.05). Both desktop and intraoral scanners showed significant differences in accuracy according to the types of teeth (P < 0.001), and the accuracy of intraoral scanners tended to get worse from anterior to posterior. Therefore, when scanning a complete arch using an intraoral scanner, the clinician should consider the tendency for the accuracy to decrease from anterior to posterior. | Son, Keunbada; Lee, Kyu-bok | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57202916520; 15925571200 | sonkeunbada@gmail.com;kblee@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 13 | 7 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2020 | 3.623 | 20.6 | 2.34 | 2025-06-25 | 50 | 50 | dental 3D scanner; accuracy; desktop scanner; intraoral scanner; tooth type | 4 INTRAORAL SCANNERS; PRECISION; IMPRESSIONS; MODEL | Accuracy; Dental 3D scanner; Desktop scanner; Intraoral scanner; Tooth type | Computer aided design; Multispectral scanners; Scanning; 3-D scanner; 3D inspection; Desktop scanners; High-precision; Reference modeling; Test Modeling; Threedimensional (3-d); Tooth type; Analysis of variance (ANOVA) | English | 2020 | 2020-04 | 10.3390/ma13071744 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
