| ○ | Article | REAL HYPERSURFACES WITH SEMI-PARALLEL NORMAL JACOBI OPERATOR IN THE REAL GRASSMANNIANS OF RANK TWO | In this paper, we introduce the notion of a semi-parallel normal Jacobi operator for a real hypersurface in the real Grassmannian of rank two, denoted by Q(m) (e), where e = +/- 1. Here, Q(m) (e) represents the complex quadric Q(m) (1) = SOm+2/SOmSO2 for e = 1 and Q(m) (-1) = SOm,20/SOmSO2 for e = -1, respectively. In general, the notion of semi- parallel is weaker than the notion of parallel normal Jacobi operator. In this paper we prove that the unit normal vector field of a Hopf real hypersurface in Q(m) (e), m > 3, with semi-parallel normal Jacobi operator is singular. Moreover, the singularity of the normal vector field gives a nonexistence result for Hopf real hypersurfaces in Q(m) (e), m > 3, admitting a semi- parallel normal Jacobi operator. | Lee, Hyunjin; Suh, Young jin | Chosun Univ, Dept Math Educ, Gwangju 61452, South Korea; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea | lhjibis@hanmail.net;yjsuh@knu.ac.kr; | GLASNIK MATEMATICKI | GLAS MAT | 0017-095X | 1846-7989 | 59 | 2 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2024 | 0.6 | 58.3 | 0 | Semi-parallelism; normal Jacobi operator; !I- isotropic; !I- principal; real hypersurfaces; real Grassmannian of rank two; complex quadric; complex hyperbolic quadric | COMPLEX PROJECTIVE-SPACE; EINSTEIN HYPERSURFACES; NONEXISTENCE | English | 2024 | 2024-12 | 바로가기 | 바로가기 | ||||||||||||

An element (x(1), ... , x(n)) is an element of E-n is called a norming point of T is an element of L(E-n) if parallel to x(1)parallel to = ... = parallel to x(n)parallel to = 1 and vertical bar T(x(1), ... , x(n))vertical bar = parallel to T parallel to, where L(E-n) denotes the space of all continuous n-linear forms on E.

For m is an element of N, m >= 2, we characterize Norm(T) for any T is an element of L((m)l(1)(n)), where l(1)(n) = R-n with the l(1)-norm. As applications, we classify Norm(T) for every T is an element of L((m)l(1)(n)) with n = 2, 3 and m = 2. | Kim, Sung Guen | Kyungpook Natl Univ, Dept Math, Daegu, South Korea | 34769667700 | sgk317@knu.ac.kr; | UKRAINIAN MATHEMATICAL JOURNAL | UKR MATH J+ | 0041-5995 | 1573-9376 | 76 | 3 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2024 | 0.6 | 58.3 | 0 | 2025-05-07 | 0 | 0 | English | 2024 | 2024-08 | 10.1007/s11253-024-02329-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||
| ○ | ○ | Article | Facile synthesis process for preparing silicon carbide with unique honeycomb structure | This study introduces a novel and versatile method for synthesizing honeycomb-structured silicon carbide (SiC). The innovative approach utilizes a sucrose solution as the carbon source and nonporous silica spheres, which serve both as silicon precursors and templates, allowing for precise control over pore sizes. Notably, the process is characterized by its cost-effectiveness, eco-friendliness, and the utilization of milder conditions attributed to magnesiothermic reduction. The tunable pore sizes achieved through adjustments in the size of silica particles offer a versatile platform for customizing SiC materials to meet specific application requirements. Beyond its customizable nature, the method reduces the environmental footprint of SiC synthesis by utilizing eco-friendly materials. Its combined attributes of accessibility, sustainability, and performance optimization underscore its potential for driving advancements in SiC-based applications across various industrial and scientific domains. image | Nguyen, Quynh Thi; Luu, Quy Son; Kim, Jiwon; Do, Uyen Thi; Park, Yeeun; Kim, Jihyun; Lee, Youngbok | Hanyang Univ, Dept Appl Chem, Ansan, South Korea; Hanyang Univ, Dept Bionano Technol, Ctr Bionano Intelligence Educ & Res, Ansan, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu, South Korea | Nguyen, Quynh/P-8620-2018 | 57277807900; 57203743030; 57277647000; 57221097554; 58031998900; 56954528100; 57061063600 | jkim23@knu.ac.kr;yblee@hanyang.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 45 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2024 | 2.2 | 58.4 | 0 | 2025-05-07 | 0 | 0 | honeycomb structure; magnesiothermic reduction; silica template; silicon carbide; sucrose; tunable pore size | NANOPARTICLES; NANOMATERIALS; SI | honeycomb structure; magnesiothermic reduction; silica template; silicon carbide; sucrose; tunable pore size | Cost effectiveness; Honeycomb structures; Silica; Silicon carbide; Sugar (sucrose); Sustainable development; Facile synthesis; Innovative approaches; Magnesiothermic reduction; Novel methods; Silica templates; Sucrose solution; Synthesis process; Tunable pore size; Tunables; Versatile methods; Pore size | English | 2024 | 2024-03 | 10.1002/bkcs.12817 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Highly active cobalt(II) and copper(II) complexes supported by aminomethylquinoline mediating stereoselective ring-opening polymerization of rac-lactide | Cobalt(II) and copper(II) complexes supported by 4-(quinolin-2-ylmethyl)morpholine (L) were characterized, and their reactivity toward the ring-opening polymerization (ROP) of rac-lactide (rac-LA) was studied. The use of [LMCl2]/(LiOPr)-Pr-i and [LMCl2]/LiMe (M = Co, Cu) resulted in over 95% conversion within 10 min at 25 degrees C. The effect of the initiating group and geometry of the metal complexes steered the heterotactic enchainment of the resultant polylactide(PLA). The Co(II)/LiMe system represents the first example of the ROP of rac-LA with high heterotactic enchainment (P-r = 0.92) with 98% conversion at 0 degrees C. | Lee, Jaegyeong; Nayab, Saira; Kumar, Ameet; Kim, Dongil; Jung, Hyewon; Lee, Sang-Ho; Cho, Daeheum; Lee, Hyosun | Kyungpook Natl Univ, Dept Chem, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, 80 Daehakro, Daegu 41566, South Korea; Shaheed Benazir Bhutto Univ SBBU, Dept Chem, Sheringal, Khyber Pakhtunk, Pakistan; Korea Res Inst Chem Technol, Ctr Adv Specialty Chem, Ulsan 44412, South Korea; Dongguk Univ, Dept Chem & Biochem Engn, Seoul, South Korea | Cho, Daeheum/D-9235-2018; Nayab, Saira/JBS-3013-2023; Lee, Sang-Ho/T-3699-2019 | 57202254509; 36490286400; 58364876900; 35474978000; 58036668300; 58743026900; 55263218400; 15750846000 | slee@krict.re.kr;daeheumc@knu.ac.kr;hyosunlee@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 45 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2024 | 2.2 | 58.4 | 0.52 | 2025-05-07 | 4 | 3 | aminomethylquinoline; cobalt-complex; copper-complex; heterotactic PLA; ring-opening polymerization | ETHYLENE TETRAMERIZATION; METHYL-METHACRYLATE; STRUCTURAL-CHARACTERIZATION; LIGANDS; TRIMERIZATION; CATALYST; OLIGOMERIZATION; DERIVATIVES; CU(II); TRI | aminomethylquinoline; cobalt-complex; copper-complex; heterotactic PLA; ring-opening polymerization | Cobalt compounds; Copper compounds; Metal complexes; Aminomethylquinoline; Cobalt complexes; Cobalt complexes (III); Copper complexes; Heterotactic polylactide; Morpholines; Poly lactide; Rac-lactide; Ring-opening polymerization; Stereo-selective; Ring opening polymerization | English | 2024 | 2024-04 | 10.1002/bkcs.12828 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | NOE analysis using dual injection DNP-NMR for studies of solvent-solute interactions at low concentrations | Dynamic nuclear polarization (DNP) offers significant signal enhancement compared to conventional nuclear magnetic resonance (NMR) in measuring the nuclear Overhauser effect. Owing to this enhancement, DNP enables the quantitative analysis of solvent-solute interactions, which are typically challenging to assess using standard NMR techniques. However, current experimental setups generally require the use of samples with relatively high solute concentrations because of large dilution factors. This limits the studies on solvent-solute interactions for bio-related molecules, particularly those with low solubility. In such cases, the concentration of solute post-dilution often falls below the detection limits. Herein, we introduce a novel dual injection system designed to considerably increase the dilution factor, thereby enabling the use of samples with lower solute concentrations while maintaining detectable signal levels. The effectiveness of this system was demonstrated in experiments using trifluoroacetic acid at concentrations 50 times lower than those used in the conventional method. | Kim, Jihyun | Kyungpook Natl Univ, Dept Chem Educ, Daegu 41566, South Korea | 56954528100 | jkim23@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 45 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2024 | 2.2 | 58.4 | 0 | 2025-05-07 | 0 | 0 | dissolution dynamic nuclear polarization; hyperpolarization; intermolecular interactions; nuclear magnetic resonance spectroscopy | CROSS-RELAXATION; WATER; DISSOLUTION; CONTACT | dissolution dynamic nuclear polarization; hyperpolarization; intermolecular interactions; nuclear magnetic resonance spectroscopy | Nuclear magnetic resonance; Solvents; Spin polarization; Dilution factors; Dissolution dynamic nuclear polarization; Dissolution dynamics; Dual injections; Dynamic nuclear polarization; Hyperpolarization; Intermolecular interactions; Low concentrations; Solute concentrations; Solvent-solute interactions; Nuclear magnetic resonance spectroscopy | English | 2024 | 2024-06 | 10.1002/bkcs.12852 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Removal of Acid Orange 7 dye using Makgeolli lees with ultrasonic assistance | This study investigated the efficient removal of Acid Orange 7 (AO7) dye in water by using Makgeolli lees, a popular by-product obtained during the production of traditional Makgeolli beverages in Korea. By incorporating ultrasound, the effects of contact time, Makgeolli lees dosage, initial AO7 dye concentration, and initial pH of the dye solution were investigated and comprehensively compared with the same experiment using the stirring method. The results consistently showed ultrasound not only enhances the excellent adsorption ability of Makgeolli lees but also accelerates the process compared to the stirring method. The Langmuir isotherm model best described the adsorption process for both methods, suggesting monolayer adsorption on the surface of Makgeolli lees, with maximum capacities of 25.13 mg/g for ultrasound at 40 kHz and 20.41 mg/g for stirring methods. Furthermore, the study showed that optimal dye removal efficiency can be achieved with ultrasound conditions at 28 kHz frequency, 125 W/L power density, and 100% ultrasound intensity. This research promises that the integration of low-cost biomass coupled with ultrasound could provide a potential solution for dye wastewater treatment.

| ○ | ○ | Article | Stress Analysis of Graphite Anode under Various Binder Conditions in a Multiparticle Model through Multiscale Simulation and Experimental Verification | Quantifying and analyzing the stress of the battery system at different levels are important for ensuring battery stability and performance. Herein, a three-dimensional multiparticle model to evaluate the stress generated within the active material particles of battery due to the particle-particle and particle-binder interactions is developed. Variations in binder conditions, such as binder distribution, thickness, and radius, as well as Young's modulus, are introduced to investigate their effects on the mechanical stress of graphite particles in the battery. Herein, it is demonstrated that larger binder distributions, lower thicknesses, and smaller Young's moduli and radii reduce the maximum particle stress of graphite. Moreover, smaller binder distributions and Young's moduli along with larger thicknesses and radii reduce the maximum and average binder stress values. The interfaces between the particle-particle and particle-current collector are the typical maximum stress locations. The average stress data obtained are applied at the electrode level for comparison with the experimental stress value. The experimental and the model average stresses are comparable, indicating the credibility of our model. These findings have considerable implications for minimizing the mechanical stress and probability of electrode fracture in the battery electrode operation and fabrication processes. The effects of lithium-ion diffusion on the stress of both the active material particles and binder are investigated using multiscale model of graphite anode. The distribution, thickness, and size of the binders are critical to the average and maximum stresses. The model's average stress is validated by comparing it to that of the experiment. image (c) 2023 WILEY-VCH GmbH | Park, Jae Hyun; Choi, Jong Eun; Kim, Sung Yeol | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | kim, sung/D-1412-2013; Kim, Sung Yeol/D-1412-2013 | 58700156500; 58398330000; 19337822900 | sykim.knu@gmail.com; | ENERGY TECHNOLOGY | ENERGY TECHNOL-GER | 2194-4288 | 2194-4296 | 12 | 2 | SCIE | ENERGY & FUELS | 2024 | 3.6 | 58.5 | 0.25 | 2025-05-07 | 2 | 2 | binder; fracture; graphite; multiparticle; stress | ION; GENERATION; PARTICLES; ELECTRODE; FRACTURE; BATTERIES; MECHANISM | binder; fracture; graphite; multiparticle; stress | Elastic moduli; Electric batteries; Electrodes; Graphite; Stress analysis; Average stress; Binder distribution; Condition; Graphite anode; Mechanical stress; Multi-particle models; Multiparticles; Stress values; Stresses analysis; Young modulus; Fracture | English | 2024 | 2024-02 | 10.1002/ente.202300898 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Occupation classification model based on DistilKoBERT: using the 5th and 6th Korean Working Condition Surveys | Background: Accurate occupation classification is essential in various fields, including policy development and epidemiological studies. This study aims to develop an occupation classification model based on DistilKoBERT. Methods: This study used data from the 5th and 6th Korean Working Conditions Surveys conducted in 2017 and 2020, respectively. A total of 99,665 survey participants, who were nationally representative of Korean workers, were included. We used natural language responses regarding their job responsibilities and occupational codes based on the Korean Standard Classification of Occupations (7th version, 3-digit codes). The dataset was randomly split into training and test datasets in a ratio of 7:3. The occupation classification model based on DistilKoBERT was fine-tuned using the training dataset, and the model was evaluated using the test dataset. The accuracy, precision, recall, and F1 score were calculated as evaluation metrics. Results: The final model, which classified 28,996 survey participants in the test dataset into 142 occupational codes, exhibited an accuracy of 84.44%. For the evaluation metrics, the precision, recall, and F1 score of the model, calculated by weighting based on the sample size, were 0.83, 0.84, and 0.83, respectively. The model demonstrated high precision in the classification of service and sales workers yet exhibited low precision in the classification of managers. In addition, it displayed high precision in classifying occupations prominently represented in the training dataset. Conclusions: This study developed an occupation classification system based on DistilKoBERT, which demonstrated reasonable performance. Despite further efforts to enhance the classification accuracy, this automated occupation classification model holds promise for advancing epidemiological studies in the fields of occupational safety and health. | Kim, Tae-Yeon; Baek, Seong-Uk; Lim, Myeong-Hun; Yun, Byungyoon; Paek, Domyung; Zoh, Kyung Ehi; Youn, Kanwoo; Lee, Yun Keun; Kim, Yangho; Kim, Jungwon; Choi, Eunsuk; Kang, Mo-Yeol; Cho, YoonHo; Lee, Kyung-Eun; Sim, Juho; Oh, Juyeon; Park, Heejoo; Lee, Jian; Won, Jong-Uk; Lee, Yu-Min; Yoon, Jin-Ha | Yonsei Univ, Severance Hosp, Coll Med, Dept Occupat & Environm Med, Seoul, South Korea; Yonsei Univ, Coll Med, Inst Occupat Hlth, Seoul, South Korea; Yonsei Univ, Grad Sch, Dept Publ Hlth, Seoul, South Korea; Yonsei Univ, Coll Med, Grad Sch, Seoul, South Korea; Yonsei Univ, Coll Med, Dept Prevent Med, Seoul, South Korea; Seoul Natl Univ, Grad Sch Publ Hlth, Dept Environm Hlth Sci, Seoul, South Korea; Wonjin Green Hosp Occupat Environm Med, Seoul, South Korea; Univ Ulsan, Ulsan Univ Hosp, Coll Med, Dept Occupat & Environm Med, Ulsan, South Korea; Kosin Univ, Coll Med, Dept Occupat & Environm Med, Busan, South Korea; Kyungpook Natl Univ, Res Inst Nursing Innovat, Coll Nursing, Daegu, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Coll Med, Dept Occupat & Environm Med, Seoul, South Korea; Korea Occupat Safety & Hlth Agcy, Occupat Safety & Hlth Res Inst, Ulsan, South Korea | Zoh, Kyung/S-1346-2019; Kim, Tae-Yeon/AAA-4018-2020 | 57539235900; 57211161334; 57944911600; 57218175713; 6602538203; 57210012175; 57190335296; 16239056300; 35234002300; 55667927600; 59316988200; 55247686600; 56972914200; 57203464375; 57247952700; 57279832800; 59316138400; 58782869600; 7201429810; 57222034194; 35766041900 | flyinyou@gmail.com; | ANNALS OF OCCUPATIONAL AND ENVIRONMENTAL MEDICINE | ANN OCCUP ENVIRON ME | 2052-4374 | 36 | ESCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2024 | 1.8 | 58.8 | 0 | 2025-05-07 | 0 | 0 | Job classification; Natural language process; DistilKoBERT; Fine-tuning | TEXT JOB DESCRIPTIONS | DistilKoBERT; Fine-tuning; Job classification; Natural language process | adult; aged; article; benchmarking; classification; diagnosis; human; Korean (people); middle aged; occupation; occupational safety; sample size; work environment | English | 2024 | 2024-08-06 | 10.35371/aoem.2024.36.e19 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The association of job training duration and risk of depression among wage workers: an analysis of the mediating factors | Background: Research on job training and job satisfaction has been conducted from various perspectives. Job training is thought to be associated with job satisfaction, which is known as an important factor for depression among workers. We hypothesized that job training duration could influence depression through potential mediators (job satisfaction, motivation to work, and work engagement). Methods: This study encompassed participants from the sixth Korean Working Conditions Survey (KWCS), conducted between 2020 and 2021. To show the relationships between demographic or occupational characteristics and risk of depression, a chi 2 test was conducted. The association between job training duration, potential mediators, and risk of depression was analyzed by constructing multiple logistic regression models. The mediating effects of potential mediators on job training duration and risk of depression was evaluated with flexible mediation analysis with weighting -based methods. Results: The final study population consisted of 25,294 participants. Longer job training duration significantly decreased risk of depression after adjusting for confounders. In the group that received the longest job training duration (>= 10 days), compared with the group without job training, the odds ratio (OR) for high risk of depression was 0.46 (95% confidence interval [CI], 0.39-0.54). Each three potential mediators showed statistically significant indirect effects and direct effect. Although indirect effects were not strong compared to direct effect, motivation to work had the strongest mediating effect in this study, with an OR of 0.94 (95% CI, 0.92-0.95). Conclusions: Job training duration was found to have a statistically significant negative association on the risk of depression, and three mediators partially mediating this effect. Although the mechanism was unknown, our findings suggest that job training has a positive influence on workers' mental health. Furthermore, by suggesting the possibility of other pathways existing between job training and depression, we provide directions for future research. | Kim, Dong Geon; Kim, Dong Kyu; Baek, Kiook | Dongguk Univ Gyeongju Hosp, Dept Occupat & Environm Med, Gyeongju, South Korea; Dongguk Univ Gyeongju Hosp, Dept Prevent Med, Gyeongju, South Korea; Kyungpook Natl Univ, Dept Med, Grad Sch, Daegu, South Korea; Yeungnam Univ Hosp, Dept Occupat & Environm Med, 170 Hyeonchung Ro, Daegu 42415, South Korea | 58680912900; 57222034551; 57190335322 | bko8899@gmail.com; | ANNALS OF OCCUPATIONAL AND ENVIRONMENTAL MEDICINE | ANN OCCUP ENVIRON ME | 2052-4374 | 36 | 1 | ESCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2024 | 1.8 | 58.8 | 0 | 2025-05-07 | 0 | 0 | Depression; Job training; Job satisfaction; Mediation analysis; Work motivation; Work engagement | WELL-BEING INDEX; SATISFACTION; SYMPTOMS; VERSION; WHO-5 | Depression; Job satisfaction; Job training; Mediation analysis; Work engagement; Work motivation | adult; Article; confidence interval; demographics; depression; duration; face-to-face interview; female; genetics; Hamilton Depression Rating Scale; human; human experiment; job performance; job satisfaction; job stress; job training; logistic regression analysis; major clinical study; male; mental health; middle aged; motivation; multivariate logistic regression analysis; odds ratio; Patient Health Questionnaire 9; questionnaire; reliability; risk factor; training; Utrecht work engagement scale; WHO-5 Well-Being Index; work environment | English | 2024 | 2024-03-22 | 10.35371/aoem.2024.36.e7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Characterization of Transparent Electrodes with Ag Metal-mesh using MATLAB | It is well-known that optical transparence and electric resistance have a trade-off relationship in transparent electrodes. For this reason, developing methods to predict this relation have been important in various fields of academic research as well as for industrial applications. Herein, we suggest a simple method which reveals the relationship between optical transparence and electric resistance using MATLAB, based on the geometric characteristics of a random metal network. Ag metal-mesh transparent electrodes were fabricated with various conditions using colloidal silica cracked-templates and a Radio Frequency (RF) sputtering system. MATLAB software was used to analyze structural images of the Ag mesh network, automatically quantifying the density and width of the Ag meshes. From these data, the transparency and sheet resistance values of the Ag mesh electrodes were predicted and compared with measured values. Regarding transparency, the introduction of fitting parameters revealed minimal differences between the experimental and predicted values obtained from the structure images. Although the predicted sheet resistance was slightly different than the real measured values due to atomic defects or imperfections in the crystals of the Ag-mesh network, it was possible to observe a similar trend between the measured and predicted sheet resistances with changes in the fractional coverage area of the Ag-mesh network. | Jo, Seung-Taek; Shin, Jin Wook; Commerell, Walter; Yoo, Dae-Hwang; Yoo, Hyesun; Hwang, Jinyoung; Kim, Hyun-Sik; Kim, Sang-il; Roh, Jong Wook | Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Gyeongsangbuk Do 37224, South Korea; TH Ulm THU, Inst Energy & Drive Technol, D-89081 Ulm, Germany; Kyungpook Natl Univ, Reg Leading Res Ctr RLRC Smart Energy Syst, Gyeongsangbuk Do 37224, South Korea; Korea Aerosp Univ, Sch Elect & Informat Engn, Gyeonggi Do 10540, South Korea; Univ Seoul, Dept Mat Sci & Engn, Seoul 02504, South Korea | Yoo, Hyesun/LFU-1949-2024 | 59177187500; 59178094400; 56431049800; 7103242532; 57211941826; 56898317100; 56526077500; 36171889900; 25638796100 | sang1.kim@uos.ac.kr;jw.roh@knu.ac.kr; | KOREAN JOURNAL OF METALS AND MATERIALS | KOREAN J MET MATER | 1738-8228 | 62 | 6 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2024 | 1.4 | 58.9 | 0.38 | 2025-05-07 | 0 | 1 | transparent electrodes; Ag; mesh-network; MATLAB; transmittance; resistance | SILVER NANOWIRE NETWORKS; COMPOSITE ELECTRODES; PATTERNS | Ag; MATLAB; mesh-network; resistance; transmittance; transparent electrodes | Economic and social effects; Electric resistance; Industrial research; MATLAB; Mesh generation; Silica; Transparency; Transparent electrodes; Academic research; Ag; Measured values; MeshNetworks; Metal-mesh; Optical-; Resistance; Trade-off relationship; Transmittance; Transparent electrode; Sheet resistance | Korean | 2024 | 2024-06 | 10.3365/kjmm.2024.62.6.464 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Complete chloroplast genome of Sagina maxima A. Gray (Caryophyllaceae) from Ulleung-do Island, Korea | Sagina maxima is an annual herb distributed in East Asia and North America. In this study, we sequenced and characterized the chloroplast genome (cp.) of S. maxima. The complete cp. genome of S. maxima is 151,507 bp long and comprises a large single-copy (LSC) region (83,669 bp), a small single-copy (SSC) region (17,220 bp), and a pair of inverted repeats (IRs) (25,309 bp) with 36.6% GC content. A unique set of 112 genes were identified which includes 78 protein-coding genes, 30 tRNA and 4 rRNA. Total 18 genes were duplicated within the IR regions and 16 genes have one intron and only clpP gene with two introns. LSC/IR junction located in the rps19 while SSC/IR junction located in ycf1. The average number of codon usage is 26,080 for all protein-coding genes in the cp. genome. There were 26 long repeats and 40 simple sequence repeats in the cp. genome, which were mostly, located in intergenic spacer (IGS) regions. This study provides the first brief characterization report of the cp. genome from the genus Sagina, which will be useful in future investigations into the genetic resources, species identification, and phylogeny of Sagina. | Tamboli, Asif S.; Kadam, Suhas K.; Youn, Jin-Suk; Yang, Jiyoung; Sim, Young Seok; Pak, Jae Hong; Choo, Yeon-Sik | Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, Dept Biol, Daegu, South Korea | Kadam, Dr Suhas/HNI-6437-2023; Kadam, Dr. Suhas/HNI-6437-2023; Tamboli, Asif/HJB-2803-2022 | 56974034100; 57188723669; 57210840807; 55193226000; 57219400815; 7102232932; 26040458100 | yschoo@knu.ac.kr; | ALL LIFE | ALL LIFE | 2689-5293 | 2689-5307 | 17 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 1.1 | 58.9 | 0 | 2025-05-07 | 0 | 0 | Caryophyllaceae; chloroplast genome; Sagina maxima; Ulleung-do Island | SEQUENCE | Caryophyllaceae; chloroplast genome; Sagina maxima; Ulleung-do Island | English | 2024 | 2024-12-31 | 10.1080/26895293.2024.2402861 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Al Addition to Mg Melt on Microstructure of Mg-Ti Composites in Liquid Metal Dealloying Process | This study investigates the effect of adding Al to Mg molten metal on the microstructural characteristics and hardness of Mg-Ti composites fabricated via a liquid metal dealloying (LMD) process. The addition of Al to the Mg melt significantly reduces the dealloying rate of Cu in a Ti30Cu70 precursor during LMD. The rapid reaction of Al atoms with Ti results in the formation of a Ti3Al phase, which in turn inhibits the spinodal decomposition of Ti and Cu. This inhibition decreases the formation rate of alpha-Mg channels, thereby slowing down the dealloying process of Cu. As a result, as the Al content in the Mg melt increases from 0 to 3 to 6 wt%, the residual Cu content in the composite substantially increases from 0 to 42 wt%. The main phases comprising the composite change from Mg and Ti for the composite using a pure Mg melt to TixCuy, TixAly, and MgxCuy for the composites using Mg-Al melts. The hardnesses of the composites fabricated using the Mg-3Al and Mg-6Al melts are 344 and 354 Hv, respectively, which are more than twice that of the composite fabricated using the pure Mg melt (116 Hv). These results demonstrate that adding small amounts of Al to Mg melt considerably influences the dealloying behavior during LMD as well as the resultant microstructure and mechanical properties of the Mg-Ti composite. | Jang, Jee Eun; Joo, Soo Hyun; Park, Sung Hyuk | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Grad Sch Mat Sci & Engn, Daegu 41566, South Korea; Dankook Univ, Dept Mat Sci & Engn, Cheonan 31116, South Korea | joo, soohyun/E-8292-2013 | 57660564800; 35738843100; 54786002500 | sh.park@knu.ac.kr; | KOREAN JOURNAL OF METALS AND MATERIALS | KOREAN J MET MATER | 1738-8228 | 62 | 10 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2024 | 1.4 | 58.9 | 0 | 2025-05-07 | 0 | 0 | Liquid metal dealloying; Mg-Ti composite; Al addition; Microstructure; Hardness | MATRIX COMPOSITES | Al addition; Hardness; Liquid metal dealloying; Mg-Ti composite; Microstructure | Copper; Copper alloys; Dealloying; Magnesium alloys; Rockwell hardness; Titanium alloys; Titanium compounds; Addition of Al; Al additions; Al phase; Dealloying; Liquid metal dealloying; Mg-ti composite; Microstructural characteristics; Pure Mg; Rapid reactions; Spinodals; Brinell Hardness | Korean | 2024 | 2024-10 | 10.3365/kjmm.2024.62.10.820 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
