| ○ | ○ | Article | Ultrafast Near-Ideal Phase-Change Memristive Physical Unclonable Functions Driven by Amorphous State Variations | There is an ever-increasing demand for next-generation devices that do not require passwords and are impervious to cloning. For traditional hardware security solutions in edge computing devices, inherent limitations are addressed by physical unclonable functions (PUF). However, realizing efficient roots of trust for resource constrained hardware remains extremely challenging, despite excellent demonstrations with conventional silicon circuits and archetypal oxide memristor-based crossbars. An attractive, down-scalable approach to design efficient cryptographic hardware is to harness memristive materials with a large-degree-of-randomness in materials state variations, but this strategy is still not well understood. Here, the utilization of high-degree-of-randomness amorphous (A) state variations associated with different operating conditions via thermal fluctuation effects is demonstrated, as well as an integrated framework for in memory computing and next generation security primitives, viz., APUF, for achieving secure key generation and device authentication. Near ideal uniformity and uniqueness without additional initial writing overheads in weak memristive A-PUF is achieved. In-memory computing empowers a strong exclusive OR (XOR-) and-repeat A PUF construction to avoid machine learning attacks, while rapid crystallization processes enable large-sized-key reconfigurability. These findings pave the way for achieving a broadly applicable security primitive for enhancing antipiracy of integrated systems and product authentication in supply chains. | Go, Shao-Xiang; Wang, Qiang; Lim, Kian Guan; Lee, Tae Hoon; Bajalovic, Natasa; Loke, Desmond K. | Singapore Univ Technol & Design, Dept Sci Math & Technol, Singapore 487372, Singapore; Univ Cambridge, Dept Engn, Trumpington St, Cambridge CB2 1PZ, England; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | ; Lee, Tae/AAB-7490-2021; Wang, Qiang/AAV-7131-2021 | 57226116052; 57219146363; 7403175755; 55731221000; 57207854156; 36096853500 | desmond_loke@sutd.edu.sg; | ADVANCED SCIENCE | ADV SCI | 2198-3844 | 9 | 36 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 15.1 | 6.8 | 0.56 | 2025-06-25 | 6 | 6 | amorphous materials; digital memory; security; function; simulations | CHANGE MEMORY; HARDWARE SECURITY; INTERNET; NUCLEATION; DEPOSITION; DEVICES; THINGS; GROWTH; FILMS; PUF | amorphous materials; digital memory; security, function; simulations | Amorphous materials; Authentication; Cryptography; Hardware security; Random processes; Sensitive data; Silicon compounds; Supply chains; Amorphous state; Degree of randomness; Digital memory; Edge computing; Phase Change; Security functions; Security primitives; Security solutions; Simulation; Ultra-fast; Phase change materials | English | 2022 | 2022-12 | 10.1002/advs.202204453 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Wireless Non-Invasive Monitoring of Cholesterol Using a Smart Contact Lens | Herein, a wireless and soft smart contact lens that enables real-time quantitative recording of cholesterol in tear fluids for the monitoring of patients with hyperlipidemia using a smartphone is reported. This contact lens incorporates an electrochemical biosensor for the continuous detection of cholesterol concentrations, stretchable antenna, and integrated circuits for wireless communication, which makes a smartphone the only device required to operate this lens remotely without obstructing the wearer's vision. The hyperlipidemia rabbit model is utilized to confirm the correlation between cholesterol levels in tear fluid and blood and to confirm the feasibility of this smart contact lens for diagnostic application of cholesterol-related diseases. Further in vivo tests with human subjects demonstrated its good biocompatibility, wearability, and reliability as a non-invasive healthcare device. | Song, Hayoung; Shin, Haein; Seo, Hunkyu; Park, Wonjung; Joo, Byung Jun; Kim, Jeongho; Kim, Jeonghyun; Kim, Hong Kyun; Kim, Jayoung; Park, Jang-Ung | Yonsei Univ, Inst Basic Sci IBS, Ctr Nanomed, Dept Mat Sci & Engn, Seoul 03722, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, 680 Gukchebosang Ro, Daegu 41944, South Korea; Kwangwoon Univ, Dept Elect Convergence Engn, Seoul 01897, South Korea; Kyungpook Natl Univ Hosp, Dept Ophthalmol, Biomed Inst, Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Yonsei Univ, Coll Med, Dept Med Engn, Seoul 03722, South Korea; Yonsei Univ, KIURI Inst, Seoul 03722, South Korea | Park, Jang-Ung/E-9224-2010; Kim, Jayoung/NKO-9807-2025 | 57844139600; 57222707966; 57217280976; 57410336100; 57222706899; 57219385573; 57203325076; 57218260940; 56103241400; 11739935500 | jkim@kw.ac.kr;okeye@knu.ac.kr;jayoungkim@yonsei.ac.kr;jang-ung@yonsei.ac.kr; | ADVANCED SCIENCE | ADV SCI | 2198-3844 | 9 | 28 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 15.1 | 6.8 | 5.62 | 2025-06-25 | 59 | 62 | cholesterol; healthcare device; smart contact lens; stretchable antenna; wireless communication | TEAR GLUCOSE; DEVICES; SENSOR; HEALTH | cholesterol; healthcare device; smart contact lens; stretchable antenna; wireless communication | Animals; Biosensing Techniques; Cholesterol; Contact Lenses, Hydrophilic; Humans; Rabbits; Reproducibility of Results; Tears; Biocompatibility; Cholesterol; Contact lenses; mHealth; Patient monitoring; Smartphones; Wearable antennas; cholesterol; Electrochemical biosensor; Healthcare device; Hyperlipidemia; Non-invasive monitoring; Real- time; Smart contact lens; Smart phones; Stretchable antenna; Tear fluid; Wireless communications; animal; genetic procedures; human; hydrophilic contact lens; lacrimal fluid; Leporidae; reproducibility; Diagnosis | English | 2022 | 2022-10 | 10.1002/advs.202203597 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Current progress in application of 1-Methylcyclopropene to improve postharvest quality of cut flowers | Floral senescence or petal abscission that determine cut flower quality and longevity are primarily caused by the regulation of endogenous ethylene and perception of endogenous and exogenous ethylene in floral organs (such as the petals and gynoecium), in ethylene-sensitive species. Several attempts have been made to prolong flower quality and longevity using silver ions and other chemicals that inhibit ethylene production and perception in floral organs. Among the available compounds, 1-methylcyclopropene (1-MCP) has been increasingly used as ethylene-action/perception inhibitor because of its ability to inhibit ethylene action/perception and it is environmentally safe. Although 1 -MCP has been used in several cut flower crops for about 25 years, there has been no review yet that critically emphasizes the benefits or difficulties of using this compound for the prolongation of cut flower quality and longevity. Here, we outline the role of 1-MCP in inhibiting ethylene action/perception and petal senescence in cut flowers through the blocking of receptor binding sites, and we discuss how various factors affecting efficacy of 1-MCP (such as concentration, treatment time and temperature, genotype, and flower stage) are involved in the achievement of flower longevity. Moreover, we highlight the advantages of applying nonvolatile and liquid 1-MCP formulation types, as opposed to using the conventional 1-MCP treatment (powder formulation type). We expect that this review will provide useful information for the future utilization of 1-MCP for the maintenance of cut flower longevity. | Naing, Aung Htay; Win, Nay Myo; Kyu, Swum Yi; Kang, In-Kyu; Kim, Chang Kil | Kyungpook Natl Univ, Dept Hort, Daegu 41566, South Korea; Apple Res Inst, Natl Inst Hort & Herbal Sci, RDA, Gunwi 39000, South Korea | ; Naing, Aung Htay/AAF-4277-2019 | 37112768100; 42462548000; 57211212443; 56577308800; 7409880701 | ckkim@knu.ac.kr; | HORTICULTURAL PLANT JOURNAL | HORTIC PLANT J | 2095-9885 | 2468-0141 | 8 | 6 | SCIE | HORTICULTURE;PLANT SCIENCES | 2022 | 5.7 | 6.9 | 0.37 | 2025-06-25 | 7 | 10 | 1-methylcyclopropene (1-MCP); Formulation types; Cut flowers; Ethylene perception; Ethylene binding site; Floral senescence; Flower quality | CYCLODEXTRIN-BASED NANOSPONGES; ETHYLENE PRODUCTION; VASE LIFE; PETAL ABSCISSION; 1-AMINOCYCLOPROPANE-1-CARBOXYLIC ACID; BOTRYTIS-CINEREA; INHIBITOR 1-MCP; SENESCENCE; GENES; SENSITIVITY | 1-methylcyclopropene (1-MCP); Cut flowers; Ethylene binding site; Ethylene perception; Floral senescence; Flower quality; Formulation types | English | 2022 | 2022-11 | 10.1016/j.hpj.2021.11.014 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Withaferin A mitigates metastatic traits in human oral squamous cell carcinoma caused by aberrant claudin-1 expression | Abnormal expression of claudin-1 (CLDN1) has important roles in carcinogenesis and metastasis in various cancers. The role of CLDN1 in human oral squamous cell carcinoma (OSCC) remains unknown. Here, we report the functional role of CLDN1 in metastasis of human OSCC, as a potential target regulated by withaferin A. From gene expression profiling with microarray technology, we found that the majority of notable differentially expressed genes were classified into migration/invasion category. Withaferin A impaired the motility of human OSCC cells in vitro and suppressed metastatic nodule formation in an in vivo metastasis model, both associated with reduced CLDN1. CLDN1 overexpression enhanced metastatic nodule formation in vivo, resulting in severe metastatic lesions in lung tissue. Moreover, CLDN1 expression was positively correlated to lymphatic metastasis in OSCC patients. The impaired motility of human OSCC cells upon withaferin A treatment was restored by CLDN1 overexpression. Furthermore, upregulation of let-7a induced by withaferin A was inversely correlated to CLDN1 expression. Overall, these give us an insight into the function of CLDN1 for prognosis and treatment of human OSCC, substantiating further investigation into the use of withaferin A as good anti-metastatic drug candidate. | Shin, Ji-Ae; Kim, Lee-Han; Ryu, Mi Heon; Choi, So-Young; Jin, Bohwan; Lee, WonWoo; Jung, Yun Chan; Ahn, Chi-Hyun; Ahn, Min-Hye; Hong, Kyoung-Ok; Swarup, Neeti; Chawla, Kunal; Kang, Se Chan; Hong, Seong Doo; Cho, Sung-Dae | Seoul Natl Univ, Sch Dent, Dept Oral Pathol, Seoul 03080, South Korea; Seoul Natl Univ, Dent Res Inst, Seoul 03080, South Korea; Yonsei Univ, Coll Med, Inst Immunol & Immunol Dis, Dept Microbiol, Seoul 03722, South Korea; Pusan Natl Univ, Sch Dent, Dept Oral Pathol, Yangsan Campus, Yangsan 50612, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Surg, Daegu 41940, South Korea; CHA Univ, CHA Biocomplex, Lab Anim Ctr, Seongnam 13488, South Korea; Chaon, 301-3,240 Pangyoyeok Ro, Seongnam 13493, South Korea; Georgia Inst Technol, Comp Sci Sch Interact Comp, 756 West Peachtree St, Atlanta, GA 30332 USA; Kyung Hee Univ, Grad Sch Biotechnol, Yongin 17104, South Korea; Kyung Hee Univ, Dept Oriental Med Biotechnol, Yongin 17104, South Korea | Swarup, Neeti/ABI-5736-2022 | 35330719900; 59794700800; 35771492000; 57202918688; 57201055036; 57207141171; 57193702712; 57195929402; 57199146330; 7402515597; 57201701076; 57222254557; 56718832700; 35248278600; 7404884194 | sky21sm@snu.ac.kr;efiwdsc@snu.ac.kr; | CELL BIOLOGY AND TOXICOLOGY | CELL BIOL TOXICOL | 0742-2091 | 1573-6822 | 38 | 1 | SCIE | CELL BIOLOGY;TOXICOLOGY | 2022 | 6.1 | 6.9 | 0.68 | 2025-06-25 | 8 | 8 | Claudin-1; Metastasis; Withaferin A; let-7a; Oral squamous cell carcinoma | Claudin-1; let-7a; Metastasis; Oral squamous cell carcinoma; Withaferin A | Carcinoma, Squamous Cell; Cell Line, Tumor; Cell Movement; Claudin-1; Gene Expression Regulation, Neoplastic; Head and Neck Neoplasms; Humans; Mouth Neoplasms; Squamous Cell Carcinoma of Head and Neck; Withanolides; claudin 1; long untranslated RNA; microRNA; withaferin A; claudin 1; withaferin A; withanolide; animal cell; animal experiment; animal model; animal tissue; Article; Ca9-22 cell line; carcinogenesis; cell invasion; cell migration; cell migration assay; cell viability assay; controlled study; DNA microarray; gene expression; gene ontology; gene overexpression; genetic transfection; glioblastoma; glioma; HSC-4 cell line; human; immunofluorescence; immunohistochemistry; luciferase assay; male; metastasis; mouse; protein expression; protein function; real time polymerase chain reaction; squamous cell carcinoma; transwell assay; upregulation; Western blotting; wound healing assay; cell motion; gene expression regulation; genetics; head and neck tumor; metabolism; mouth tumor; pathology; tumor cell line | English | 2022 | 2022-02 | 10.1007/s10565-021-09584-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Application of various fractal models in characterizing the morphology of pore structures of hydrating cement pastes | The pore structures of cementitious materials are very crucial to the development of the various engineering properties of these materials. Based on the importance of the pore structure, several studies have been conducted on the application of fractal geometry, which can be used as an interpretation tool for the characteristics of the pore structure as well as in various engineering phenomena. Accordingly, various fractal models have been developed from the mercury intrusion porosimetry (MIP) data. However, studies on applying the fractal model considering the characteristics of the material to be analyzed are relatively scarce. In this study, we conducted an in-depth investigation of the char-acteristics of the pore structures of cementitious materials considering both the volumetric and geometric characterization parameters. Among the three concepts of fractal di-mensions of pore-size distribution, the solid mass fractal concept exhibited the highest correlation with the degree of hydration. The fractal dimensions of pore-size distribution and pore tortuousness tended to increase as the complexity of the entire microstructures increased, mainly due to the increase in the solid phase fraction. Furthermore, the results of the correlation analysis (between the volumetric and geometric parameters) and regression analysis (between newly derived parameter and initial sorptivity) showed that fractal dimensions can be utilized as pore structure characterization parameters like the existing volumetric parameters, and these parameters serve as complementary tools for interpreting the transport properties of cementitious materials.(c) 2022 The Authors.

| ○ | ○ | Article | Assessment of optical and fluorescence aspects of Er³⁺-doped multicomponent B2O3 glasses as active media for 1.532 mm near-infrared optical amplifiers | Current work principally provides an idea on controlling the Er3+: NIR (near-infrared) emission characteristics by changing a glass constituent and finding a suitable glass host favorable to design a novel C-optical band (1.53-1.565 mm) amplifier. By melting and rapid quench route, six transparent B2O3 (1 mol%)-doped B2O3-rich glasses having different single and mixed alkali ions were fabricated, and optical and fluorescence (visible and NIR) traits including Er3+ ion upper-levels S-4(3/2) and I-4(13/2) decay dynamics were inspected for such samples. At 1.4-1.65 mu m wavelength range, an intense and wide NIR luminescence band centered at 1.532 mu m (Er3+: I-4(13/2) / I-4(15/2) transition) has been obtained by a 980 mu m laser diode pumping (I-4(15/2) / I-4(11/2)). NIR fluorescence Delta lambda(eff) (effective bandwidth) varied depending on added single or mixed alkali ions, and a maximum Delta lambda(eff) similar to 74.66 nm was acquired for Er3+ : Li ions constituting glass. For the I-4(13/ 2) / I-4(15/2) transition, semi (stimulated emission cross-section) was evaluated using both FuchtbauereLadenburg and McCumber's theories. In all glasses, comparably, higher gain bandwidth (= 5.384 x 10(-26) cm(3)) and peak sigma(M)(emi) (= 1.692 x 10(-20) cm(2)) values have been attained for I-4(13/2) / I-4(15/2) transition in Li ions containing sample, and also this glass possesses the largest sabs (absorption cross-section) (= 1.459 x 10(-20) cm(2)) for I-4(15/2)/ I-4(13/2) transition. Further, at distinctive P (population inversion) values, gain spectra were computed, and all samples show C-optical band amplification beginning from P = 50%. All analyzed NIR fluorescence results indicate that Li ions having glass could be a potential gain medium for fiber amplifiers. (C) 2022 The Author(s).

| ○ | ○ | Article | Low-cycle fatigue properties and unified fatigue life prediction equation of hot-rolled twin-roll-cast AZ31 sheets with different thicknesses | This study investigates the low-cycle fatigue properties of AZ31 sheets with different thicknesses of 1, 1.5, 2, and 3 mm-which are fabricated by twin-roll casting and subsequent hot rolling-through fully reversed straincontrolled fatigue tests. As the thickness of the sheets decreases, their average grain size decreases, texture intensity increases, and tensile yield strength and elongation gradually increase. At strain amplitudes of greater than or equal to 0.6%, {10-12} twinning in compression and detwinning and subsequent slip in tension occur repeatedly, which forms asymmetric hysteresis loops. The different grain sizes of the sheets result in different compressive peak stresses during the fatigue tests. However, the overall cyclic deformation behavior is similar in all the sheets, and consequently, their fatigue lives exhibit an insignificant difference. The loading direction also has a negligible influence on both the cyclic deformation behavior and the fatigue life, which implies that the sheets exhibit in-plane isotropic fatigue properties. The stress amplitude and plastic strain amplitude vary considerably during the fatigue test. In contrast, the variation in total strain energy density is insignificant over the entire fatigue life, and therefore, it is a proper fatigue damage parameter for predicting fatigue life. A unified fatigue life prediction equation using the total strain energy density is established, and the fatigue lives predicted using the equation are found to be in good agreement with the experimentally determined values, regardless of the strain amplitude, sheet thickness, and loading direction. | Kim, Ye Jin; Cha, Jae Won; Kim, Hyun Ji; Kim, Young Min; Park, Sung Hyuk | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Korea Inst Mat Sci, Implementat Res Div, Chang Won 51508, South Korea | Kim, Young Min/HCH-5414-2022; Kim, Hyunjin/MDS-5282-2025; Park, Sung-Hyuk/AAE-6726-2022 | 59052467200; 57221282466; 59866513600; 58795669000; 54786002500 | sh.park@knu.ac.kr; | MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING | MAT SCI ENG A-STRUCT | 0921-5093 | 1873-4936 | 833 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 6.4 | 7.0 | 1.08 | 2025-06-25 | 13 | 13 | AZ31 magnesium alloy; Twin-roll casting; Cyclic deformation; Low-cycle fatigue; Fatigue life prediction | MAGNESIUM ALLOY SHEETS; MECHANICAL-PROPERTIES; DEFORMATION BEHAVIORS; GRAIN-SIZE; TEXTURE; MICROSTRUCTURE; TEMPERATURE; TENSION; DEPENDENCE; EVOLUTION | AZ31 magnesium alloy; Cyclic deformation; Fatigue life prediction; Low-cycle fatigue; Twin-roll casting | Deformation; Fatigue testing; Forecasting; Grain size and shape; Hot rolling; Magnesium alloys; Magnesium castings; Magnesium printing plates; Strain energy; Textures; AZ31 magnesium alloy; Az31 sheets; Cyclic deformations; Different thickness; Fatigue life prediction; Low cycle fatigues; Low-cycle fatigue properties; Prediction equations; Strain amplitude; Twin roll casting; Low-cycle fatigue | English | 2022 | 2022-01-26 | 10.1016/j.msea.2021.142349 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Microstructure evolution maps of AZ31 and AZ91-Ca-Y-MM alloys under precompression and subsequent annealing conditions | This study establishes the microstructure evolution maps of a commercial AZ31 alloy and a recently developed Mg-9Al-0.8Zn-0.9Ca-0.6Y-0.5MM (AZXWMM91100) alloy on the basis of their microstructural variations with precompression amount and subsequent annealing temperature. The fully twinned microstructure of precom-pressed samples of the AZ31 alloy remains unchanged after annealing at 200 C. At annealing temperatures above 225 C, the area fraction of twin-free grains gradually increases with increasing precompression amount and annealing temperature. The microstructure evolution map of the AZ31 alloy consists of three regions: those with a fully twinned grain structure, partially twinned grain structure, and completely twin-free grain structure. The twinned microstructure of precompressed samples of the AZXWMM91100 alloy remains unchanged after annealing even at 250 and 300 ?. At annealing temperatures above 350 ?, the microstructure drastically changes from a fully twinned microstructure to a completely twin-free microstructure irrespective of the pre -compression amount. Consequently, the microstructure evolution map of the AZXWMM91100 alloy does not include the region with the partially twinned grain structure. The large amount of Al solute atoms and numerous second-phase particles in the AZXWMM91100 alloy inhibit grain-boundary movement during annealing, which results in the different microstructural evolution behavior with the AZ31 alloy. | Lee, Jong Un; Kim, Ye Jin; Park, Sung Hyuk | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Park, Sung-Hyuk/AAE-6726-2022 | 57195056728; 59052467200; 54786002500 | sh.park@knu.ac.kr; | MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING | MAT SCI ENG A-STRUCT | 0921-5093 | 1873-4936 | 854 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 6.4 | 7.0 | 1.33 | 2025-06-25 | 18 | 16 | Magnesium; Precompression; Annealing; Microstructure; Twins | MECHANICAL-PROPERTIES; MAGNESIUM; RECRYSTALLIZATION; TEXTURE; BEHAVIOR; MODEL | Annealing; Magnesium; Microstructure; Precompression; Twins | Alloys; Annealing; Crystal microstructure; Grain boundaries; Grain size and shape; Annealing; Annealing temperatures; AZ31 alloy; Evolution maps; Free grains; Microstructure evolutions; Pre-compression; Twin; Twin-free; Twinned grains; Magnesium | English | 2022 | 2022-09-27 | 10.1016/j.msea.2022.143814 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optical and visible and near-infrared fluorescence aspects of Er³⁺, Tm³⁺, and Nd³⁺-doped B2O3-rich glasses for fiber amplifiers and NIR lasers | For synthesized each 1 mol% Er3+, Tm3+, and Nd3+-doped borate-rich glasses, optical and luminescence traits including fluorescence decay dynamics were explored. For Er3+: glass, at 1.4-1.65 mu m range a wide NIR (near-infrared) luminescence band centered at 1.531 mu m (I-4(13/2 & nbsp;)->& nbsp;I-4(15/2)) and in Tm3+: glass, at 1.35-1.6 mu m span a broad NIR fluorescence band centered at 1.458 mu m (H-3(4 & nbsp;)-> F-3(4)) are obtained by 980 nm LD (laser diode) pumping (I-4(15/2 & nbsp;)->& nbsp;I-4(11/2)) and 808 nm LD excitation (H-3(6 & nbsp;)-> H-3(4)) separately. Under 808 nm LD pumping (I-4(9/2 & nbsp;)->& nbsp;F-4(5/2)+H-2(9/2)), in Nd3+: glass, three emission bands peaked at 0.901 mu m (F-4(3/2 & nbsp;)->& nbsp;I-4(9/2)), 1.057 mu m (F-4(3/2 & nbsp;)->& nbsp;I-4(11/2)), and 1.329 mu m (F-4(3/2 & nbsp;)->& nbsp;I-4(13/2)) respectively are observed and in all such emissions, comparably the one obtained from transition F-4(3/2 & nbsp;)->& nbsp;I-4(11/2) is highly intense. For acquired main visible and NIR emissions, delta lambda(eff) (effective bandwidth), by Fuchtbauer-Ladenburg approach sigma(emi) (stimulated emission cross-section), gain bandwidth, and optical gain are evaluated. 75.73 nm, 113.67 nm, and 57.37 nm are the delta lambda(eff & nbsp;)values for Er3+: I-4(13/2 & nbsp;)->& nbsp;I-4(15/2), Tm3+: H-3(4 & nbsp;)-> F-3(4), and Nd3+: F-4(3/2 & nbsp;)-> I-4(13/2) transitions accordingly. Using McCumber's theory, the calculated peak sigma(emi) for Er3+: I-4(13/2 & nbsp;)->& nbsp;I-4(15/2) and Nd3+: F-4(3/2 & nbsp;)->& nbsp;I-4(9/2) transitions are 1.495 x 10-20 cm(2) and 0.5556 x 10-20 cm(2), respectively. I-4(13/2 & nbsp;)->& nbsp;I-4(15/2) transition gain cross-section spectra reveals C-band amplification at P (population inversion) = 50% in Er3+: glass, whereas at P = 30% for F-4(3/2 & nbsp;)->& nbsp;I-4(9/2) transition gain cross-section is positive for lasing action at-0.9 mm in Nd3+: glass. All analyzed NIR luminescence outcomes reveal that studied glasses could be potential gain media for C-, S-, and O-bands fiber amplifiers and solid-state lasers. (C)& nbsp;2022 The Author(s).

| ○ | ○ | Article | Simulating the γ-ray and neutron attenuation properties of lithium borate glasses doped barite: efficient and deterministic analysis using relevant simulation codes | In the present paper, we report a comprehensive theoretical study dealing with gamma-ray, fast and thermal neutrons shielding features of compositionally graded Pb-free lithium borate glasses doped barite: (B2O3)((0.6))(BaSO4)((x))(Li2O)((0.4-x)). The study has been conducted for six particular values of the LiO2 fraction (x) namely x = 0.0, 0.05, 0.075, 0.1, 0.15, and 0.2 in mol %. This choice finds its origin with the circumstance of getting nontoxic glasses characterized by a strong (X/beta)-ray absorption. WinXCOM program was used to determine mass attenuation coefficients (mu/rho) by means of a photon energy ranging from 0.015 to 15 MeV. The obtained results are compared with those evaluated with Geant4, and Penelope codes. To illustrate the key physical parameters of all glasses, namely the effective electron density (N-eff), gamma-ray attenuation parameters like effective atomic number (Z(eff)), half-value layer (HVL), as well as the mean free path (MFP) and their corresponding potential functionality, we utilize the (mu/rho) values of WinXCOM assessed within a range of photon energy varying from 0.015 to 15 MeV. We also investigate the impact of the exposure buildup factors (EBFs) as well as the energy absorption buildup factors (EABFs) by performing a geometric progression (G-P) fitting method as a function of varied penetration depths ranging from 1 to 40 mfp by step of 5 mfp. Additionally, the mass stopping power (MSP) and projected range (PR) have been estimated for alpha particles and triton particles using SRIM code within 0.01-1 MeV energy range. The results obtained herein reveal that the glass G20 is demonstrating its endorsement of a prime gamma-ray shielding effectiveness among the rest of glasses. We also proven through our numerical simulations that the glass G00 possess the relatively larger macroscopic removal cross-section for fast neutrons attenuation as well as the significant thermal neutrons absorption cross-section, in addition to the fact it holds the highest mass stopping power (MSP) and lowest projected range (PR), suggesting thereby its superior neutronic, tritonic and alpha shielding abilities.

| ○ | ○ | Article | Simultaneously Enhanced Hydrophilicity and Stability of a Metal-Organic Framework via Post-Synthetic Modification for Water Vapor Sorption/Desorption | With increasing demands for high-performance water sorption materials, metal-organic frameworks (MOFs) have gained considerable attention due to their high maximum uptake capacities. In many cases, however, high overall capacity is not necessarily accomplishing high working capacity under operating conditions, due to insufficient hydrophilicity and/or water stability. Herein, we present a post-synthetic modification (PSM) of MOF-808, with di-sulfonic acids enhancing simultaneously its hydrophilicity and water stability without sacrificing its uptake capacity of approximate to 30 mmol g(-1). Di-sulfonic acid PSM enabled a shift of the relative humidity (RH) associated with a sharp step in water vapor sorption from 35-40 % RH in MOF-808 to below 25 % RH. While MOF-808 lost uptake capacity and crystallinity over multiple sorption/desorption cycles, the di-sulfonic acid PSM MOF-808 retained >80 % of the original capacity. PSM MOF-808 exhibited good hydrothermal stability up to 60 degrees C and high swing capacity. | Luo, Tian-Yi; Park, Sunghwan; Chen, Tso-Hsuan; Prerna; Patel, Roshan; Li, Xinyu; Siepmann, J.

| ○ | ○ | Article | Variation in bending deformation behavior and improvement in bendability of extruded pure Mg through Gd addition | In this study, the twinning and slip behaviors of pure Mg and Mg-1Gd extrudates during bending deformation are investigated by subjecting the extrudates to three-point bending tests. The pure Mg extrudate has a coarse grain structure with a strong basal texture. The Mg-1Gd extrudate has a uniform and fine grain structure with a typical rare-earth (RE) texture because the added Gd causes the suppression of grain-boundary migration and the textural tilting during extrusion. When bending deformation is imposed, cracks are formed in the lower region (tension zone (TZ)) of the bending specimens of both extrudates. However, the bending yield strength and failure bending strain of the Mg-1Gd extrudate are 56% and 68% higher than those of the pure Mg extrudate, respectively. Both the extrudates exhibit similar deformation behaviors in the upper region of the bending specimens, in which {10-12} twinning is activated in most grains. However, because the activation stress for {10-12} twinning is lower in the pure Mg extrudate, its bending yield strength is lower than that of the Mg-1Gd extrudate. In the TZs of both the extrudates, a small amount of {10-12} twinning is caused by the minor tensile stress imposed along the width direction, and the dislocation slip is predominantly caused by the major tensile stress imposed along the longitudinal direction. In the TZ of the pure Mg extrudate, slip is activated to a limited extent during bending because of its strong basal texture, which is unfavorable for basal slip. In contrast, in the TZ of the Mg-1Gd extrudate, basal slip vigorously occurs owing to its RE texture. Furthermore, nonbasal slip also occurs because Gd addition reduces the difference between the critical resolved shear stresses of basal slip and nonbasal slip. Consequently, the bendability of the Mg-1Gd extrudate improves through the effective accom-modation of the longitudinal tensile strain in the TZ during bending. | Lee, Gyo Myeong; Lee, Jong Un; Park, Sung Hyuk | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Park, Sung-Hyuk/AAE-6726-2022 | 57222810183; 57195056728; 54786002500 | sh.park@knu.ac.kr; | MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING | MAT SCI ENG A-STRUCT | 0921-5093 | 1873-4936 | 855 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 6.4 | 7.0 | 1.16 | 2025-06-25 | 17 | 16 | Mg alloy; Gd addition; Bending deformation; Twinning; Slip | ABNORMAL GRAIN-GROWTH; RARE-EARTH TEXTURE; MAGNESIUM ALLOY; TENSILE PROPERTIES; MG-1GD ALLOY; AZ31 SHEET; MICROSTRUCTURE; DUCTILITY; MG-3AL-1ZN; EVOLUTION | Bending deformation; Gd addition; Mg alloy; Slip; Twinning | Bending (deformation); Bending tests; Gadolinium alloys; Grain boundaries; Grain size and shape; Magnesium alloys; Shear stress; Tensile strain; Tensile strength; Tensile stress; Textures; Yield stress; Basal slip; Basal textures; Deformation behavior; Extrudates; Gd addition; Mg alloy; Pure Mg; Rare-earths; Slip; Tension zone; Rare earths | English | 2022 | 2022-10-10 | 10.1016/j.msea.2022.143940 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | {10-12} extension twinning activity and compression behavior of pure Mg and Mg-0.5Ca alloy at cryogenic temperature | This study explored the deformation behavior of rolled pure Mg and Mg-0.5Ca alloy at room temperature (RT) and cryogenic temperature (CT) of - 150 degrees C. The samples were compressed at a strain rate of 10-3s-1 up to 5% strain along the rolling direction (RD). The deformed samples were examined via EBSD and analyzed concerning the loading condition and initial microstructure. The compression tests showed the temperature-insensitive hardening behavior in Mg-0.5Ca alloy. The twinning activity increased with an increase in grain size, and this was pronounced when the pure Mg samples were compressed at CT. The kernel average misorientation (KAM) analysis revealed that the twinning parent areas tend to have higher KAM values under CT deformation than the RT deformation, which links to a higher twinning activity at CT. The predominant low angle grain boundaries in the initial microstructure of pure Mg further helps to understand the profuse twinning activity in the context of existing literature. It was suggested that the higher twinned area fraction in the pure Mg sample than Mg-0.5Ca could be responsible for the temperature-dependent hardening behavior. This is presumably because the Ca element in the matrix results in a homogeneous microstructure with smaller grain size and higher Schmid factor (SF) for basal slip, leading to lower twinning dependent deformation behavior in Mg-0.5Ca than pure Mg. | Han, Gukin; Noh, Yeonju; Chaudry, Umer Masood; Park, Sung Hyuk; Hamad, Kotiba; Jun, Tea-Sung | Incheon Natl Univ, Dept Mech Engn, Incheon 22012, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Sungkyunkwan Univ, Sch Adv Mat Sci & Engn, Suwon 16419, South Korea; Incheon Natl Univ, Res Inst Engn & Technol, Incheon 22012, South Korea | Hamad, Kotiba/A-4246-2016; Park, Sung-Hyuk/AAE-6726-2022; Masood, Umer/AAL-6916-2020 | 57209738284; 57300846900; 57204236754; 54786002500; 36188209200; 56890702300 | t.jun@inu.ac.kr; | MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING | MAT SCI ENG A-STRUCT | 0921-5093 | 1873-4936 | 831 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 6.4 | 7.0 | 3.98 | 2025-06-25 | 43 | 48 | Magnesium; Calcium; Cryogenic deformation; Twinning; EBSD | MECHANICAL-PROPERTIES; ROOM-TEMPERATURE; MAGNESIUM ALLOYS; POLYCRYSTALLINE MAGNESIUM; DEFORMATION-BEHAVIOR; NONBASAL SLIP; CA; DUCTILITY; TEXTURE; FORMABILITY | Calcium; Cryogenic deformation; EBSD; Magnesium; Twinning | Binary alloys; Calcium; Calcium alloys; Compression testing; Cryogenics; Deformation; Grain boundaries; Grain size and shape; Hardening; Magnesium alloys; Microstructure; Twinning; Activity behavior; Cryogenic deformation; Cryogenic temperatures; Deformation behavior; EBSD; Hardening behavior; Initial microstructures; Misorientations; Pure Mg; Temperature deformation; Strain rate | English | 2022 | 2022-01-13 | 10.1016/j.msea.2021.142189 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Arbidol inhibits human esophageal squamous cell carcinoma growth in vitro and in vivo through suppressing ataxia telangiectasia and Rad3-related protein kinase | Human esophageal cancer has a global impact on human health due to its high incidence and mortality. Therefore, there is an urgent need to develop new drugs to treat or prevent the prominent pathological subtype of esophageal cancer, esophageal squamous cell carcinoma (ESCC). Based upon the screening of drugs approved by the Food and Drug Administration, we discovered that Arbidol could effectively inhibit the proliferation of human ESCC in vitro. Next, we conducted a series of cell-based assays and found that Arbidol treatment inhibited the proliferation and colony formation ability of ESCC cells and promoted G1-phase cell cycle arrest. Phosphoproteomics experiments, in vitro kinase assays and pull-down assays were subsequently performed in order to identify the underlying growth inhibitory mechanism. We verified that Arbidol is a potential ataxia telangiectasia and Rad3-related (ATR) inhibitor via binding to ATR kinase to reduce the phosphorylation and activation of minichromosome maintenance protein 2 at Ser108. Finally, we demonstrated Arbidol had the inhibitory effect of ESCC in vivo by a patient-derived xenograft model. All together, Arbidol inhibits the proliferation of ESCC in vitro and in vivo through the DNA replication pathway and is associated with the cell cycle. | Yang, Ning; Lu, Xuebo; Jiang, Yanan; Zhao, Lili; Wang, Donghao; Wei, Yaxing; Yu, Yin; Kim, Myoung Ok; Laster, Kyle Vaughn; Li, Xin; Yuan, Baoyin; Dong, Zigang; Liu, Kangdong | Zhengzhou Univ, Sch Basic Med Sci, Pathophysiol Dept, Zhengzhou, Peoples R China; China US Hormel Canc Inst, Zhengzhou, Peoples R China; Zhengzhou Univ, Collaborat Innovat Ctr Henan Prov Canc Chemopreven, Zhengzhou, Peoples R China; State Key Lab Esophageal Canc Prevent & Treatment, Zhengzhou, Peoples R China; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju, South Korea; Canc Chemoprevent Int Collaborat Lab, Zhengzhou, Peoples R China | Zhao, Lili/JEO-7007-2023; Yuan, Baoyin/AAX-7951-2021; 姜, 亚楠/GSJ-0598-2022; Wei, Yaxing/K-1507-2013 | 57204070883; 57375609200; 55779997500; 59104843700; 57221103825; 57218500212; 57225145147; 8934745900; 36637580700; 58611866400; 56316616700; 57225955964; 56890019100 | dongzg@zzu.edu.cn;kdliu@zzu.edu.cn; | ELIFE | ELIFE | 2050-084X | 11 | SCIE | BIOLOGY | 2022 | 7.7 | 7.1 | 0.2 | 2025-06-25 | 2 | 2 | ESCC; mass spectrometry; signaling pathway; Other | NONSTEROIDAL ANTIINFLAMMATORY DRUGS; DNA-DAMAGE; PHOSPHORYLATION SITES; REPLICATION STRESS; CANCER; ATR; METFORMIN; MCM2; CHEMOPREVENTION; EPIDEMIOLOGY | Apoptosis; Ataxia Telangiectasia; Cell Line, Tumor; Cell Proliferation; Esophageal Neoplasms; Esophageal Squamous Cell Carcinoma; Gene Expression Regulation, Neoplastic; Humans; Indoles; Protein Kinases; Sulfides; ATR protein; umifenovir; indole derivative; protein kinase; sulfide; umifenovir; Article; ataxia telangiectasia; cancer growth; cell cycle arrest; cell cycle G1 phase; cell proliferation; cell viability; colony formation; DNA replication; esophageal squamous cell carcinoma; esophagus cancer; gene set enrichment analysis; histology; human; human cell; IC50; minichromosome; mortality; phosphoproteomics; pull-down assay; squamous cell carcinoma; toxicity assay; tumor xenograft; Western blotting; apoptosis; esophageal squamous cell carcinoma; esophagus tumor; gene expression regulation; metabolism; pathology; tumor cell line | English | 2022 | 2022-09-09 | 10.7554/elife.73953 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Effect of diisocyanate structure on steric restructuring of hindered urea bonds for self-healable coating | Hindered-urea bonds (HUBs), made of bulky amine and isocyanate, are reversible and the reversibility generally comes from the steric hindrance of the bulky substituents on the amine. In this study, the steric effects of diisocyantes (DIs) on the reversibility of HUBs and HUB-bearing polymers were studied. An acrylic prepolymer bearing tertiary-butyl amine (PtB) was prepared and crosslinked with five different DIs. The reversibility of the HUBs as well as the thermodynamic and self-healing behaviours of the HUB-bearing polymer networks (PtB-DIs) were investigated with respect to the structure of alkyl substituents on DIs. Proton nuclear magnetic resonance (1H NMR), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and oscillatory rheometry were performed, and it was confirmed that the reversibility of the HUB increases as the order of isocyanate group increases (1° > 2° > 3°). Self-healing behaviours were examined by single scratch tests, and the self-healing efficiency increased in the same order. Blending of two isocyanates, 1,4-bis(isocyanatomethyl)benzene (XDI) and tetramethylxylene diisocyanate (TMXDI), expanded the choices for the mechanical and self-healing properties of the polymers. It was remarkable that the mechanical properties of the HUB-bearing polymers at ambient temperature were more significantly affected by the spacer structure of diisocyanate than the steric hindrance. © 2022 Elsevier B.V. | Yun, Su Min; Lee, Hyang Moo; Ahmed, Sana; Kim, Gi Young; Kim, Jin Chul; Cheong, In Woo | Department of Applied Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea, Department of Materials Science and Engineering, Yonsei University, Seoul, 03722, South Korea; Department of Applied Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Applied Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Applied Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea | 57221914764; 55598631800; 57444624300; 57210997221; 56805502600; 7006733373 | jckim81@krict.re.kr; | Progress in Organic Coatings | PROG ORG COAT | 0300-9440 | 1873-331X | 165 | SCIE | CHEMISTRY, APPLIED;MATERIALS SCIENCE, COATINGS & FILMS | 2022 | 6.6 | 7.1 | 0.6 | 2025-06-25 | 7 | Diisocyanates; Hindered-urea bond; Intrinsic self-healing; Scratch-healable coatings; Urethane-acrylates | Blending; Coatings; Differential scanning calorimetry; Metabolism; Nuclear magnetic resonance; Self-healing materials; Bulky substituents; Diisocyanates; Hindered-urea bond; Intrinsic self-healing; Scratch-healable coating; Self-healing; Steric effect; Steric hindrances; Sterics; Urethane acrylate; Urea | English | Final | 2022 | 10.1016/j.porgcoat.2022.106730 | 바로가기 | 바로가기 | 바로가기 |
