| 6 | Effect of molybdenum on interfacial properties of titanium carbide reinforced Fe composite显示文摘This study shows that the mechanical strength of the composite of Fe matrix and titanium carbide(Ti C)ceramic particles is significantly enhanced with addition of molybdenum(Mo) atoms. Ti C reinforced Fe(Fe-0.2C-7Mn) composites with and without Mo were fabricated by a liquid pressing infiltration(LPI)process and the effect of Mo on interfacial properties of TiC–Fe composite was investigated using atomic probe tomography(APT) analysis, molecular dynamics(MD) simulations, first-principle density functional theory(DFT), and thermodynamic calculations. First, DFT calculations showed that total energies of the Mo-doped Ti C–Fe superlattices strongly depend on the position of Mo defects, and are minimized when the Mo atom is located at the TiC/Fe interface, supporting the probable formation of MoC-like interphase at the TiC/Fe interface region. Then, APT analysis confirmed the DFT predictions by finding that about6.5 wt.% Mo is incorporated in the Ti C–Fe(Mo) composite and that sub-micrometer thick(Ti,Mo)C interphase is indeed formed near the interface. The MD simulations show that Mo atoms migrate to the Mo-free TiC–Fe interface at elevated temperatures and the mechanical strength of the interface is considerably enhanced, which is in good agreement with experimental observations. | Seungchan Cho Junghwan Kim Ilguk Jo Jae Hyun Park Jaekwang Lee Hyun-Uk Hong Bong Ho Lee Wook Ryol Hwang Dong-Woo Suh Sang-Kwan Lee Sang-Bok Lee | 2022 | Journal of Materials Science & Technology2022，，12： | 0 |
| 7 | Bulk-Si photonics technology for DRAM interface[Invited]显示文摘We present photonics technology based on a bulk-Si substrate for cost-sensitive dynamic random-access memory(DRAM)optical interface application.We summarize the progress on passive and active photonic devices using a local-crystallized Si waveguide fabricated by solid phase epitaxy or laser-induced epitaxial growth on bulk-Si substrate.The process of integration of a photonic integrated circuit(IC)with an electronic IC is demonstrated using a 65 nm DRAM periphery process on 300 mm wafers to prove the possibility of seamless integration with various complementary metal-oxide-semiconductor devices.Using the bulk-Si photonic devices,we show the feasibility of high-speed multidrop interface:the Mach–Zehnder interferometer modulators and commercial photodetectors are used to demonstrate four-drop link operation at 10 Gb∕s,and the transceiver chips with photonic die and electronic die work for the DDR3 DRAM interface at 1.6 Gb∕s under a 1∶4 multidrop configuration. | Hyunil Byun Jinkwon Bok Kwansik Cho Keunyeong Cho Hanmei Choi Jinyong Choi Sanghun Choi Sangdeuk Han Seokyong Hong Seokhun Hyun TJJeong Ho-Chul Ji In-Sung Joe Beomseok Kim Donghyun Kim Junghye Kim Jeong-Kyoum Kim Kiho Kim Seong-Gu Kim Duanhua Kong Bongjin Kuh Hyuckjoon Kwon Beomsuk Lee Hocheol Lee Kwanghyun Lee Shinyoung Lee Kyoungwon Na Jeongsik Nam Amir Nejadmalayeri Yongsang Park Sunil Parmar Junghyung Pyo Dongjae Shin Joonghan Shin Yong-hwack Shin Sung-Dong Suh Honggoo Yoon Yoondong Park Junghwan Choi Kyoung-Ho Ha Gitae Jeong | 2014 | Photonics Research2014，2，3： | 0 |
| 8 | Dietary sophorolipid accelerates growth by modulation of gut microbiota population and intestinal environments in broiler chickens显示文摘Background:Gut is a crucial organ for the host’s defense system due to its filtering action of the intestinal membrane from hazardous foreign substances.One strategy to strengthen the gut epithelial barrier function is to upregulate beneficial microflora populations and their metabolites.Sophorolipid(SPL),which is a glycolipid biosurfactant,could increase beneficial microflora and decrease pathogenic bacteria in the gastrointestinal tract.Therefore,herein,we conducted an experiment with broiler chickens to investigate the fortifying effects of SPL on the host’s gut defense system by modulating the microbiota population.Methods:A total of 5401-day-old chicks(Ross 308)were used,and they were immediately allotted into three treatment groups(6 replications with 30 chicks/pen)according to their initial body weight.The dietary treatments consisted of CON(basal diet),BAM(10 mg/kg bambermycin),and SPL(10 mg/kg SPL).During the experiment,birds freely accessed feed and water,and body weight and feed intake were measured at the end of each phase.On d 35,birds(one bird/pen)were sacrificed to collect jejunum and cecum samples.Results:Dietary SPL and BAM supplementation significantly accelerated birds’growth and also significantly improved feed efficiency compared to CON.Intestinal microbial community was significantly separated by dietary SPL supplementation from that of CON,and dietary SPL supplementation significantly increased Lactobacillus spp.and Akkermansia muciniphila.Moreover,birds fed with dietary SPL also showed the highest concentration of cecal butyrate among all treatment groups.Gut morphological analysis showed that dietary SPL significantly increased villus height,ratio of villus height to crypt depth,goblet cell numbers,and the gene expression levels of claudin-1 and mucin 2.Additionally,dietary SPL significantly decreased the mRNA expression level of pro-inflammatory cytokine,interleukin-6,and increased that of anti-inflammatory cytokine,interleukin-10,compared to other treatments.Conclusions:Dietary SPL increases the beneficial bacterial population and butyrate concentration,which leads to a strengthened gut barrier function.In addition,the intestinal inflammation was also downregulated by dietary SPL supplementation. | Min-Jin Kwak Min-Young Park Yong-Soon Choi Junghwan Cho Duleepa Pathiraja Jonggun Kim Hanbae Lee In-Geol Choi Kwang-Youn Whang | 2022 | Journal of Animal Science and Biotechnology2022，13，1： | 0 |
