| ○ | ○ | Article | Ni-W-P layer-induced strength improvement of solder joint in Bi2Te3 thermoelectric module | In this study, we examined the thermal stability, bonding strength, and interfacial characteristic of a Ni-W-P coating applied for solder joint of Bi2Te3 thermoelectric modules. This layer had uniform thickness and was confirmed to be amorphous even after annealing at 200 degrees C for 150 h, demonstrating its thermal stability. Moreover, the barrier layer hindered the interdiffusion between Sn and Te, eliminating the formation of brittle intermetallic at the solder joint. Thus, the bonding strengths of p- and n-type thermoelectric units were improved approximately 1.3- and 2.8-fold, respectively, compared to the bonding strengths obtained without a Ni-W-P layer. In addition, the bonding strength was not affected by heating at 200 degrees C for 150 h. The reliability of bonding strength was caused by the excellent thermal stability, and solder wettability of the barrier layer, which resulted in a bonding interface without brittle intermetallic and defects. | Bae, Sung Hwa; Nguyen, Yen Ngoc; Son, Injoon | Kyushu Univ, Grad Sch Engn, Fukuoka, Japan; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Nguyen, Yen/CAJ-4943-2022 | 57210171283; 57197767959; 9942975800 | ijson@knu.ac.kr;nnyen@knu.ac.kr; | SCIENCE AND TECHNOLOGY OF WELDING AND JOINING | SCI TECHNOL WELD JOI | 1362-1718 | 1743-2936 | 28 | 5 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2023 | 3.1 | 21.7 | 1 | 2025-06-25 | 6 | 8 | solder joint; electroless deposition; Ni-W-P; diffusion barrier; contact; thermoelectric; Bi2Te3 | INTERFACIAL REACTIONS; TEMPERATURE; SN | Bi<sub>2</sub>Te<sub>3</sub>; contact; diffusion barrier; electroless deposition; Ni–W–P; solder joint; thermoelectric | Bismuth compounds; Diffusion barriers; Diffusion bonding; Nickel compounds; Tellurium compounds; Thermodynamic stability; Thermoelectric equipment; Thermoelectricity; Barrier layers; Bonding strength; Contact; Ni–W–P; P-layer; Solder joints; Strength characteristics; Strength improvements; Thermo-electric modules; Thermoelectric; Intermetallics | English | 2023 | 2023-07-04 | 10.1080/13621718.2023.2167039 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Ninhydrin Loaded Microcapsules for Detection of Natural Free Amino Acid | Natural free amino acids present in plant extracts or tea infusions provide a unique flavor and potential effect on anxiety and blood pressure reduction. Accordingly, quantifying free amino acids in foods has been of interest to food science and analytical research fields. The ninhydrin solution-based assay is a colorimetric method based on the formation and detection of Ruhemann's purple complex. Media-based colorimetric detection requires specialized facilities and personnel; moreover, it can suffer from the interference of the analyte color. In this study, we developed ninhydrin-loaded microcapsules and a simple free amino acids detection procedure, by simply dipping the microcapsules into the analyte solution for 3 min. Among the five tested natural free amino acids, theanine exhibited the highest colorimetric response to microcapsule-based detection, with a limit of detection of 0.826 mM. | Jeong, Suhui; Jeon, Yeji; Mun, Jaehun; Jeong, Se Min; Liang, Huiling; Chung, Kyeongwoon; Yi, Pyong-In; An, Beum-Soo; Seo, Sungbaek | Pusan Natl Univ, Life & Ind Convergence Res Inst, Coll Nat Resources & Life Sci, Dept Biomat Sci, Miryang 50463, South Korea; Zhejiang Univ, Tea Res Inst, 268 Kaixuan Rd, Hangzhou 310029, Peoples R China; Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Pusan Natl Univ, Coll Nat Resource & Life Sci, Dept Bioenvironm Energy, Miryang 50463, South Korea | ; Jeong, Se-Min/AAI-7581-2021 | 57442444400; 58024384100; 58078679800; 58079183300; 7402853689; 56416916000; 57186239600; 7007154153; 55189636300 | sbseo81@pusan.ac.kr; | CHEMOSENSORS | CHEMOSENSORS | 2227-9040 | 11 | 1 | SCIE | CHEMISTRY, ANALYTICAL;ELECTROCHEMISTRY;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.7 | 21.7 | 1.04 | 2025-06-25 | 8 | 9 | microcapsules; natural free amino acid; ninhydrin; theanine | TEA; THEANINE | microcapsules; natural free amino acid; ninhydrin; theanine | Aspartame; Blood pressure; Analytes; Blood pressure reductions; Food science; Free amino acids; Microcapsules; Natural free amino acid; Ninhydrin; Potential effects; Tea infusion; Theanine | English | 2023 | 2023-01 | 10.3390/chemosensors11010049 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | One-Pot Synthesis of Nanostructured Ni@Ni(OH)2 and Co-Doped Ni@Ni(OH)2 via Chemical Reduction Method for Supercapacitor Applications | Crystalline Ni@Ni(OH)(2) (cNNH) and Co-doped cNNH were obtained via a simple one-pot hydrothermal synthesis using a modified chemical reduction method. The effect of each reagent on the synthesis of the nanostructures was investigated concerning the presence or absence of each reagent. The detailed morphology shows that both nanostructures consist of a Ni core and Ni(OH)(2) shell layer (similar to 5 nm). Co-doping influences the morphology and suppresses the particle agglomeration of cNNH. Co-doped cNNH showed a specific capacitance of 1238 F g(-1) at 1 A g(-1) and a capacitance retention of 76%, which are significantly higher than those of cNNH. The enhanced performance of the co-doped cNNH is attributed to the reduced path length of the electrons caused by the decrease in the size of the nanostructure and the increased conductivity due to Co ions substituting Ni ions. The reported synthesis method and electrochemical behaviors of cNNH and Co-doped cNNH affirm their potential as electrochemically active materials for supercapacitor applications. | Eom, Seungyong; Jung, Jinjoo; Kim, Do Hyung | Kyungpook Natl Univ, Dept Phys, Nano Appl Phys Lab, Daegu 702701, South Korea | 57225075182; 55750032400; 57007491900 | kimdh@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 1 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 0.37 | 2025-06-25 | 3 | 3 | core-shell; nickel hydroxide; chemical reduction; formation mechanism; hydrothermal; supercapacitor | HIGH-PERFORMANCE; NICKEL NANOCRYSTALLITES; HYDROXIDE; ELECTRODE; ALPHA-NI(OH)(2); NANOPARTICLES; POLYMER; COMPLEX | chemical reduction; core–shell; formation mechanism; hydrothermal; nickel hydroxide; supercapacitor | Capacitance; Hydrothermal synthesis; Morphology; Nanostructures; Nickel compounds; Reduction; Chemical reduction; Chemical reduction methods; Co-doped; Core shell; Formation mechanism; Hydrothermal; Nanostructured Ni; Nickel hydroxides; One-pot synthesis; Supercapacitor application; Supercapacitor | English | 2023 | 2023-01 | 10.3390/ma16010380 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Preparation and Characterization of Poly(Acrylic Acid)-Based Self-Healing Hydrogel for 3D Shape Fabrication via Extrusion-Based 3D Printing | The three-dimensional (3D) printing of hydrogel is an issue of interest in various applications to build optimized 3D structured devices beyond 2D-shaped conventional structures such as film or mesh. The materials design for the hydrogel, as well as the resulting rheological properties, largely affect its applicability in extrusion-based 3D printing. Here, we prepared a new poly(acrylic acid)-based self-healing hydrogel by controlling the hydrogel design factors based on a defined material design window in terms of rheological properties for application in extrusion-based 3D printing. The hydrogel is designed with a poly(acrylic acid) main chain with a 1.0 mol% covalent crosslinker and 2.0 mol% dynamic crosslinker, and is successfully prepared based on radical polymerization utilizing ammonium persulfate as a thermal initiator. With the prepared poly(acrylic acid)-based hydrogel, self-healing characteristics, rheological characteristics, and 3D printing applicability are deeply investigated. The hydrogel spontaneously heals mechanical damage within 30 min and exhibits appropriate rheological characteristics, including G 'similar to 1075 Pa and tan delta similar to 0.12, for extrusion-based 3D printing. Upon application in 3D printing, various 3D structures of hydrogel were successfully fabricated without showing structural deformation during the 3D printing process. Furthermore, the 3D-printed hydrogel structures exhibited excellent dimensional accuracy of the printed shape compared to the designed 3D structure. | Shin, Woohyeon; Chung, Kyeongwoon | Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Sch Mat Sci & Engn, Ulsan 44919, South Korea | 57222326165; 56416916000 | kychung@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 5 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 0.87 | 2025-06-25 | 7 | 7 | poly(acrylic acid); extrusion-based 3D printing; hydrogel; self-healing polymer; rheological characteristics | DRUG-RELEASE | extrusion-based 3D printing; hydrogel; poly(acrylic acid); rheological characteristics; self-healing polymer | Ammonium persulfate; Carboxylic acids; Extrusion; Fabrication; Hydrogels; Rheology; Self-healing materials; 3-D printing; 3D-printing; Extrusion-based 3d printing; Materials design; Poly(acrylic acid); Rheological characteristics; Rheological property; Self-healing; Self-healing polymers; 3D printing | English | 2023 | 2023-03 | 10.3390/ma16052085 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Preparation and Characterization of Thermal-Insulating Microporous Breathable Al/LLDPE/CaCO3 Composite Films | Breathable films were prepared based on linear low-density polyethylene (LLDPE), calcium carbonate (CaCO3), and aluminum (Al; 0, 2, 4, and 8 wt.%) using extrusion molding at a pilot scale. These films must generally be able to transmit moist vapor through pores (breathability) while maintaining a barrier to liquids; this was accomplished using properly formulated composites containing spherical CaCO3 fillers. The presence of LLDPE and CaCO3 was confirmed by X-ray diffraction characterization. Fourier-transform infrared spectroscopy results revealed the formation of Al/LLDPE/CaCO3 composite films. The melting and crystallization behaviors of the Al/LLDPE/CaCO3 composite films were investigated using differential scanning calorimetry. Thermogravimetric analysis results show that the prepared composites exhibited high thermal stability up to 350 & DEG;C. Moreover, the results demonstrate that surface morphology and breathability were both influenced by the presence of various Al contents, and their mechanical properties improved with increasing Al concentration. In addition, the results show that the thermal insulation capacity of the films increased after the addition of Al. The composite with 8 wt.% Al showed the highest thermal insulation capacity (34.6%), indicating a new approach to transform composite films into novel advanced materials for use in the fields of wooden house wrapping, electronics, and packaging. | Lee, Jungeon; Yeasmin, Sabina; Jung, Jae Hoon; Kim, Tae Young; Kwon, Tae Yeong; Kwon, Da Yeong; Yeum, Jeong Hyun | Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Carbon Hybrid Fiber Sci, Daegu 41566, South Korea; Hans Intech Co Ltd, Daegu 41243, South Korea | 57559595700; 57216565706; 58476748000; 57208461628; 58476514600; 57249227800; 6602257098 | dlwjddjs2@gmail.com;yeasminsabina44@yahoo.com;wjdwognsz@naver.com;xodud10301@naver.com;kty7289@naver.com;dayoung962001@naver.com;jhyeum@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 12 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 0.12 | 2025-06-25 | 1 | 1 | composites; extrusion molding; aluminum; morphology; breathability; thermal insulation; thermal properties; mechanical properties | POLYPROPYLENE SHEETS; MECHANICAL-PROPERTIES; POLYETHYLENE FILMS; CACO3 FILLER; CRYSTALLIZATION | aluminum; breathability; composites; extrusion molding; mechanical properties; morphology; thermal insulation; thermal properties | Aluminum; Aluminum compounds; Calcite; Crystallization; Differential scanning calorimetry; Extrusion molding; Film preparation; Fourier transform infrared spectroscopy; Morphology; Packaging; Packaging materials; Surface morphology; Thermal insulation; Thermogravimetric analysis; Aluminum (Al); Breathability; Breathable films; Insulation capacity; Linear low-density polyethylene; Melting and crystallization; Microporous; Pilot scale; Thermal-insulating; X- ray diffractions; Calcium carbonate | English | 2023 | 2023-06 | 10.3390/ma16124230 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Quality Characteristics and Antioxidant Activities of Six Types of Korean White Wine | The cultivation of European grape cultivars suitable for winemaking in Korea presents challenges due to factors such as climate, soil conditions, precipitation, and sunlight. Consequently, Korea has traditionally resorted to adding sugar to its wine production to counteract the low sugar content in Korean grapes, yielding lower-quality wines. However, recent success in the cultivation of five European grape cultivars and the development of the domestic grape cultivar Cheongsoo have increased the possibility of achieving high-quality Korean wines. This study aimed to explore the potential of European grape cultivars and Cheongsoo as wine grapes in Korea. This study also conducted sensory evaluation and analyzed the physicochemical properties of the grapes and wines, including antioxidant capacity and color. Despite originating from the same vineyard, the composition of grapes and wines, including volatile aromatic compounds, significantly differed among the grape cultivars. In particular, Vidal wine exhibited superior antioxidant capacity compared with other wines. Moreover, Cheongsoo wine showed higher levels of essential volatile aromatic compounds, such as monoterpenes, than other wines. Sensory evaluation of these two wines also revealed excellent results. In conclusion, these findings hold promise for enhancing the diversity of Korean white wine and fostering growth in the wine industry. | Lee, Sae-Byuk | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Fermentat Biotechnol, 80 Daehakro, Daegu 41566, South Korea | 57188742752 | lsbyuck@knu.ac.kr; | FOODS | FOODS | 2304-8158 | 12 | 17 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 4.7 | 21.7 | 0.79 | 2025-06-25 | 1 | 4 | white wine; Cheongsoo grape; antioxidant activity; white grape; wine | GC-MS ANALYSIS; SENSORY PROFILE; GRAPE; VOLATILE; FERMENTATION; AROMA; RESVERATROL; YEASTS | antioxidant activity; Cheongsoo grape; white grape; white wine; wine | English | 2023 | 2023-09 | 10.3390/foods12173246 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Quality Characteristics of Rice-Based Ice Creams with Different Amylose Contents | Ice cream consumption has increased over the years. In this study, we investigated the potential of using rice varieties with varying amylose contents for ice cream production. We analyzed the physical and chemical properties and sensory quality characteristics (appearance, taste, texture, chewiness, aroma, and rice flavor) of rice-based ice cream made from five varieties with low and high amylose levels. To make the ice cream, we ground rice into a fine powder and combined it with skim milk powder, butter, sugar, glycerin esters of fatty acids, locust bean gum, and water to form a gelatinized mixture. This mixture was then aged, frozen, and hardened. The ice cream's key quality characteristics, such as viscosity (2170-25,030 cP), hardness (4.27-49.55 N cm(-2)), and overrun (17.95-46.99%), showed a wide range. Ice cream made from Saemimyeon (high amylose content rice variety) exhibited the highest hardness value (49.55 N cm(-2)) among the varieties tested, but had relatively low viscosity (4030 cP), overrun (17.95%), and drip-through (0.75 g/min) values. These findings suggest that rice varieties with different amylose contents are suitable for making ice cream and have the potential to expand the rice processing market and increase its value. | Seong, Gi-Un; Kim, Ji-Yoon; Kim, Jung-Soo; Jeong, Sae-Ul; Cho, Jun-Hyeon; Lee, Ji-Yoon; Lee, Sais-Beul; Kabange, Nkulu-Rolly; Park, Dong-Soo; Moon, Kwang-Deog; Kang, Ju-Won | Rural Dev Adm, Natl Inst Crop Sci, Dept Southern Area Crop Sci, Miryang 50424, South Korea; Kyungpook Natl Univ, Sch Food Sci & Technol, Daegu 41566, South Korea; Rural Dev Adm, Natl Inst Crop Sci, Sangju 37139, South Korea | ; KABANGE, NKULU/AAQ-9425-2020 | 56814555600; 57208110209; 57211108486; 57219605598; 49663022700; 57203144726; 56512821400; 57202031236; 55724788100; 55999192900; 18040021700 | kdmoon@knu.ac.kr;kangjw81@korea.kr; | FOODS | FOODS | 2304-8158 | 12 | 7 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 4.7 | 21.7 | 0.2 | 2025-06-25 | 1 | 1 | rice; ice cream; amylose content; physicochemical properties; sensory quality | PHYSICOCHEMICAL PROPERTIES; FUNCTIONAL-PROPERTIES; STRUCTURAL-PROPERTIES; PHYSIOCHEMICAL PROPERTIES; SENSORY CHARACTERISTICS; PASTING PROPERTIES; WAXY GENE; GELATINIZATION; STARCHES; FLOURS | amylose content; ice cream; physicochemical properties; rice; sensory quality | English | 2023 | 2023-04 | 10.3390/foods12071518 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Quercetin-Induced Glutathione Depletion Sensitizes Colorectal Cancer Cells to Oxaliplatin | Quercetin is an antioxidant phytochemical which belongs to the natural flavonoids group. Recently, the compound has been reported to inhibit glutathione reductase responsible for replenishing reduced forms of glutathione and thus leads to glutathione depletion, triggering cell death. In this study, we examined if quercetin sensitizes tumors to oxaliplatin by inhibiting glutathione reductase activity in human colorectal cancer cells, and thereby facilitates apoptotic cell death. A combined treatment with quercetin and oxaliplatin was found to synergistically inhibit glutathione reductase activity, lower intracellular glutathione level, increase reactive oxygen species production, and reduce cell viability, compared to treatment with oxaliplatin alone in human colorectal HCT116 cancer cells. Furthermore, the incorporation of sulforaphane, recognized for its ability to scavenge glutathione, in combination with quercetin and oxaliplatin, substantially suppressed tumor growth in an HCT116 xenograft mouse model. These findings suggest that the depletion of intracellular glutathione by quercetin and sulforaphane could strengthen the anti-cancer efficacy of oxaliplatin. | Lee, Jinkyung; Jang, Chan Ho; Kim, Yoonsu; Oh, Jisun; Kim, Jong-Sang | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Daegu Gyeongbuk Med Innovat Fdn, New Drug Dev Ctr, Daegu 41061, South Korea | 57546632200; 24477187500; 57219254485; 56311554100; 37106950100 | joh@kmedihub.re.kr;vision@knu.ac.kr; | FOODS | FOODS | 2304-8158 | 12 | 8 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 4.7 | 21.7 | 3.75 | 2025-06-25 | 18 | 20 | quercetin; sulforaphane; glutathione reductase; oxidative stress; anti-cancer; oxaliplatin; apoptosis | MULTIDRUG-RESISTANCE; MOLECULAR-MECHANISMS; PHARMACOKINETICS; TRANSPORTERS; FLAVONOIDS | anti-cancer; apoptosis; glutathione reductase; oxaliplatin; oxidative stress; quercetin; sulforaphane | English | 2023 | 2023-04 | 10.3390/foods12081733 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Residual Compressive Strength Prediction Model for Concrete Subject to High Temperatures Using Ultrasonic Pulse Velocity | This study measured and analyzed the mechanical properties of normal aggregate concrete (NC) and lightweight aggregate concrete (LC) subjected to high temperatures. The target temperature was set to 100, 200, 300, 500, and 700 degrees C, and W/C was set to 0.41, 0.33 and 0.28 to evaluate high temperature properties at various intensities. Measurement parameters included mass loss, compressive strength, ultrasonic pulse velocity (UPV), and elastic modulus. We compared the residual mechanical properties between the target and preheating temperatures (20 degrees C) and then analyzed the correlation between UPV and compressive strength. According to the research findings, after exposure to high temperatures, LC demonstrated a higher mass reduction rate than NC at all levels and exhibited higher residual mechanical properties. The results of analyzing the correlation between compressive strength and UPV for concrete subjected high temperatures were very different from the compressive strength prediction equation previous proposed at room temperature, and the error range of the residual strength prediction equation considering W/C was reduced. | Kim, Wonchang; Choi, Hyeonggil; Lee, Taegyu | Semyung Univ, Dept Fire & Disaster Prevent, Jecheon Si 27136, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil Engn, Daegu 41566, South Korea | 57659934800; 56430165800; 7501437272 | hgchoi@knu.ac.kr;ltg777@semyung.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 2 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 1.5 | 2025-06-25 | 11 | 12 | high temperature; ultrasonic pulse velocity; compressive strength; type of coarse aggregate; water-binder; prediction model | ELEVATED-TEMPERATURES; MECHANICAL-PROPERTIES; AGGREGATE CONCRETE | compressive strength; high temperature; prediction model; type of coarse aggregate; ultrasonic pulse velocity; water-binder | Concrete aggregates; Forecasting; Light velocity; Light weight concrete; Aggregate concrete; Coarse aggregates; Highest temperature; Lightweight aggregates; Prediction modelling; Strength prediction; Target temperature; Type of coarse aggregate; Ultrasonic pulse velocity; Water-binder; Compressive strength | English | 2023 | 2023-01 | 10.3390/ma16020515 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Synthesis of Novel Shape Memory Thermoplastic Polyurethanes (SMTPUs) from Bio-Based Materials for Application in 3D/4D Printing Filaments | Bio-based thermoplastic polyurethanes have attracted increasing attention as advanced shape memory materials. Using the prepolymer method, novel fast-responding shape memory thermoplastic polyurethanes (SMTPUs) were prepared from 100% bio-based polyester polyol, poly-propylene succinate derived from corn oil, diphenyl methane diisocyanate, and bio-based 1,3-propanediol as a chain extender. The morphologies of the SMTPUs were investigated by Fourier transform infrared spectroscopy, atomic force microscopy, and X-ray diffraction, which revealed the interdomain spacing between the hard and soft phases, the degree of phase separation, and the intermixing level between the hard and soft phases. The thermal and mechanical properties of the SMTPUs were also investigated, wherein a high hard segment content imparted unique properties that rendered the SMTPUs suitable for shape memory applications at varying temperatures. More specifically, the SMTPUs exhibited a high level of elastic elongation and good mechanical strength. Following compositional optimization, a tensile strength of 24-27 MPa was achieved, in addition to an elongation at break of 358-552% and a hardness of 84-92 Shore A. Moreover, the bio-based SMTPU exhibited a shape recovery of 100%, thereby indicating its potential for use as an advanced temperature-dependent shape memory material with an excellent shape recoverability. | Jung, Yang-Sook; Lee, Sunhee; Park, Jaehyeung; Shin, Eun-Joo | Dong A Univ, Dept Organ Mat & Polymer Engn, Pusan 49315, South Korea; Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Dong A Univ, Dept Fash Design, Pusan 49315, South Korea | 57802210500; 57207067693; 55566554000; 55984568700 | parkj@knu.ac.kr;sejoo6313@dau.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 3 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 1.87 | 2025-06-25 | 12 | 15 | shape memory polymer; thermoplastic polyurethane; bio-based material; shape recoverability | BEHAVIOR; POLYMERS; DIISOCYANATE; SEPARATION; PROPERTY; NETWORK | bio-based material; shape memory polymer; shape recoverability; thermoplastic polyurethane | Fourier transform infrared spectroscopy; Polyurethanes; Reinforced plastics; Shape optimization; Shape-memory polymer; Tensile strength; Bio-based; Bio-based materials; Hard phase; Prepolymer method; Shape memory polymers; Shape memory thermoplastic polyurethanes; Shape recoverability; Shape-memory materials; Soft phasis; Thermoplastic polyurethanes; Phase separation | English | 2023 | 2023-02 | 10.3390/ma16031072 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Effect of Boron (B) and Copper (Cu) on the Microstructure and Graphite Morphology of Spheroidal Graphite Cast Iron | This study examines the impacts of copper and boron in parts per million (ppm) on the microstructure and mechanical properties of spheroidal graphite cast iron (SCI). Boron's inclusion increases the ferrite content whereas copper augments the stability of pearlite. The interaction between the two significantly influences the ferrite content. Differential scanning calorimetry (DSC) analysis indicates that boron alters the enthalpy change of the & alpha; + Fe3C & RARR; & gamma; conversion and the & alpha; & RARR; & gamma; conversion. Scanning electron microscope (SEM) analysis confirms the locations of copper and boron. Mechanical property assessments using a universal testing machine show that the inclusion of boron and copper decreases the tensile strength and yield strength of SCI, but simultaneously enhances elongation. Additionally, in SCI production, the utilization of copper-bearing scrap and trace amounts of boron-containing scrap metal, especially in the casting of ferritic nodular cast iron, offers potential for resource recycling. This highlights the importance of resource conservation and recycling in advancing sustainable manufacturing practices. These findings provide critical insights into the effects of boron and copper on SCI's behavior, contributing to the design and development of high-performance SCI materials. | Ha, Jin-Su; Hong, Ji-Woo; Kim, Ji-Wook; Han, Soo-Bin; Choi, Chang-Young; Song, Hye-Jin; Jang, Jin-Seok; Kim, Dong-Yul; Ko, Dae-Cheol; Yi, Seong-Hoon; Cho, Yong-Jae | Korea Inst Ind Technol, Smart Mfg Technol R&D Grp, Daegu 42994, South Korea; Gyeongbuk Res Inst Vehicle Embedded Technol, Yeongcheon Si 38822, South Korea; Pusan Natl Univ, Dept Nanomechatron Engn, Pusan 46241, South Korea; Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea | 58220959800; 58417669700; 57192960123; 57996703700; 59078917900; 56707858600; 35766806500; 57260987900; 7103246008; 14008383000; 56390097200 | jinsu302@kitech.re.kr;wldn4116@kitech.re.kr;wkim0@kitech.re.kr;soobin35@kitech.re.kr;cy8584@kitech.re.kr;shyejin@kitech.re.kr;jsjang@kitech.re.kr;dykim@givet.re.kr;dcko@pusan.ac.kr;yish@knu.ac.kr;asycast@kitech.re.kr;easycast@kitech.re.kr; | MATERIALS | MATERIALS | 1996-1944 | 16 | 12 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 3.1 | 21.7 | 0.62 | 2025-06-25 | 5 | 5 | spheroidal graphite cast iron; boron; pearlite; mechanical properties; microstructure | EUTECTOID TRANSFORMATION; AS-CAST; MATRIX | boron; mechanical properties; microstructure; pearlite; spheroidal graphite cast iron | Boron; Cast iron; Conservation; Differential scanning calorimetry; Ferrite; Iron compounds; Morphology; Natural resources; Pearlite; Recycling; Scanning electron microscopy; Scrap metal reprocessing; Tensile strength; Tensile testing; Trace elements; Copper cu; Electron microscope analysis; Enthalpy change; Ferrite content; Graphite morphology; Microstructure morphologies; Microstructures and mechanical properties; Parts per millions; Scanning electrons; Spheroidal graphite cast iron; Microstructure | English | 2023 | 2023-06 | 10.3390/ma16124225 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Association between serum total cholesterol and chronic kidney disease progression in children: results from the KNOW-PedCKD | Background Dyslipidemia can cause cardiovascular disease and increase the fatality rate among children with chronic kidney disease (CKD); this makes early screening and treatment of dyslipidemia crucial. This study aimed to assess the association between the changes in serum total cholesterol levels over time and the degree of CKD progression in children.Methods From April 2011 to August 2021, 379 of the 432 participants enrolled in the KoreaN cohort study for Outcomes in patients With Pediatric CKD (KNOW-PedCKD) were included and divided into 4 categories based on total cholesterol levels (< 170 mg/dL, acceptable; 170-199, borderline; 200-239, high; and = 240, very high). Survival analysis using conventional and time-dependent Cox proportional hazards model were performed for a composite event of CKD progression (= 50% decrease in estimated glomerular filtration rate from baseline, a twofold increase in creatinine, or the occurrence of dialysis or kidney transplantation).Result The incidence of composite event of CKD progression was 96.3, 90.4, 87.3, and 270.6 cases per 1000 person-years in the acceptable, borderline, high, and very high categories, respectively. On using the time-dependent Cox proportional hazards model, the hazard ratio of the very high category was significantly higher than that of the acceptable category by 3.13 times as per univariate analysis and 2.37 times as per multivariate analysis.Conclusions Very high serum total cholesterol is a significant risk factor for CKD progression in children. Lowering total cholesterol levels below the very high category in children with CKD may delay the progression of CKD. | Baek, Hee Sun; Park, Min Ji; Song, Ji Yeon; Kim, Seong Heon; Kang, Hee Gyung; Ahn, Yo Han; Han, Kyoung Hee; Cho, Heeyeon; Lee, Keum Hwa; Shin, Jae Il; Park, Young Seo; Lee, Joo Hoon; Park, Eujin; Yang, Eun Mi; Cho, Min Hyun | Yeungnam Univ, Coll Med, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Pusan Natl Univ, Childrens Hosp, Sch Med, Dept Pediat, Busan, South Korea; Seoul Natl Univ, Dept Pediat, Childrens Hosp, Seoul, South Korea; Jeju Natl Univ Hosp, Dept Pediat, Jeju, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Pediat, Sch Med, Seoul, South Korea; Yonsei Univ, Dept Pediat, Coll Med, Seoul, South Korea; Univ Ulsan, Childrens Hosp, Dept Pediat, Coll Med,Asan Med Ctr, Seoul, South Korea; Korea Univ, Coll Med, Dept Pediat, Guro Hosp, Seoul, South Korea; Chonnam Natl Univ Hosp, Dept Pediat, Gwangju, South Korea | SHIN, JAE IL/J-6922-2017; Lee, Seok/ABF-7548-2020; Kim, Seong/AAD-8853-2020 | 56689379700; 57425372600; 57204058871; 57213778393; 7404071546; 57219957477; 58389645900; 15724272900; 57193231590; 57964880100; 56701214400; 37112404100; 56194662500; 56665095200; 7401727726 | chomh@knu.ac.kr; | PEDIATRIC NEPHROLOGY | PEDIATR NEPHROL | 0931-041X | 1432-198X | 38 | 12 | SCIE | PEDIATRICS;UROLOGY & NEPHROLOGY | 2023 | 2.6 | 21.8 | 1.66 | 2025-06-25 | 5 | 6 | Children; Chronic kidney disease; Dyslipidemia; Cardiovascular disease; Total cholesterol; CKD progression | CLINICAL-PRACTICE GUIDELINES; RENAL-DISEASE; YOUNG-ADULTS; DYSLIPIDEMIA; ADOLESCENTS; CKD; MORTALITY; OUTCOMES; STATINS; IMPACT | Cardiovascular disease; Children; Chronic kidney disease; CKD progression; Dyslipidemia; Total cholesterol | Child; Cholesterol; Cohort Studies; Disease Progression; Dyslipidemias; Glomerular Filtration Rate; Humans; Renal Dialysis; Renal Insufficiency, Chronic; Risk Factors; cholesterol; creatinine; high density lipoprotein cholesterol; low density lipoprotein cholesterol; triacylglycerol; cholesterol; adolescent; adult; Article; child; childhood disease; cholesterol blood level; chronic kidney failure; cohort analysis; controlled study; creatinine blood level; disease exacerbation; estimated glomerular filtration rate; female; high risk population; human; infant; lipid analysis; major clinical study; male; newborn; observational study; predictive value; preschool child; prospective study; risk assessment; risk factor; school child; survival analysis; survival rate; triacylglycerol blood level; young adult; chronic kidney failure; disease exacerbation; dyslipidemia; glomerulus filtration rate; hemodialysis | English | 2023 | 2023-12 | 10.1007/s00467-023-06033-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Early Discontinuation of Levothyroxine Treatment Is Safe and Feasible in Extremely Low Birth Weight Infants with Delayed Hyperthyrotropinemia | Background: While recent pieces of evidence suggest that discontinuation of levothyroxine replacement therapy (LRT) earlier than the current guidelines of 3 years is possible, the optimal duration of LRT for delayed hyperthyrotropinemia in extremely low birth weight infants (ELBWIs) remains unknown. Objective: This study aimed to investigate the feasibility of early discontinuation of LRT for delayed hyperthyrotropinemia in ELBWIs. Methods: The medical records of 92 ELBWIs who had shown delayed hyperthyrotropinemia, defined as a delayed rise in thyroid-stimulating hormone (TSH) levels to >20 mu IU/mL after initial normal TSH level, were retrospectively reviewed to determine whether the duration of LRT affects the short-term outcomes at discharge from neonatal intensive care unit (NICU) and the long-term outcomes at the corrected age (CA) of 2 years. The infants were grouped into: no LRT required group (n = 21), short-term LRT given until the time of NICU discharge - 90 +/- 64 (13-211) days group (n = 36), and long-term LRT given - 749 +/- 333 (339-1,967) days group (n = 35). Results: While mortality in the no LRT required group was significantly higher than that in the long-term LRT group, no significant differences were observed in short-term outcomes at discharge from NICU and long-term growth and neurodevelopmental outcomes at CA of 2 years between the short- and long-term LRT groups. Conclusions: Termination of LRT at around the time of discharge from NICU in well, clinically stable ELBWIs who have delayed hyperthyrotropinemia appears to be safe and feasible and avoids the risk of overtreatment. | Kim, Ji Sook; Chang, Yun Sil; Ahn, So Yoon; Sung, Se In; Yang, Mi Sun; Park, Won Soon | Kyungpook Natl Univ, Childrens Hosp, Sch Med, Dept Pediat, Daegu, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Pediat, Sch Med, Seoul, South Korea | Ahn, Soyoon/LIC-5007-2024; Park, Won/C-9652-2011 | 57194705685; 14041061300; 50060961300; 55270548900; 57211042406; 55664488700 | ws123.park@samsung.com; | NEONATOLOGY | NEONATOLOGY | 1661-7800 | 1661-7819 | 120 | 1 | SCIE | PEDIATRICS | 2023 | 2.6 | 21.8 | 0.27 | 2025-06-25 | 4 | 1 | Thyroid hormone; Extremely preterm infants; Hyperthyrotropinemia; Thyroxine treatment | HYPOTHYROIDISM; CHILDREN; TRANSIENT; EVOLUTION; THERAPY; HORMONE | Extremely preterm infants; Hyperthyrotropinemia; Thyroid hormone; Thyroxine treatment | Child, Preschool; Humans; Infant; Infant, Extremely Low Birth Weight; Infant, Newborn; Intensive Care Units, Neonatal; Retrospective Studies; Thyrotropin; Thyroxine; levothyroxine; thyrotropin; thyrotropin; thyroxine; Article; Bayley Scales of Infant Development; brain development; cesarean section; child growth; clinical assessment; clinical outcome; controlled study; demographics; disorders of hormone metabolism; drug effect; extremely low birth weight; feasibility study; female; follow up; hospital discharge; human; hyperthyrotropinemia; incidence; infant; major clinical study; male; medical record; morbidity; mortality; neonatal intensive care unit; outcome assessment; patient safety; prevalence; retrospective study; substitution therapy; thyroid function test; thyrotropin blood level; treatment duration; treatment withdrawal; newborn; preschool child | English | 2023 | 2023-03 | 10.1159/000526701 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
