1Theoretical prediction,synthesis,and crystal structure determination of new MAX phase compound V2SnC显示文摘Guided by the theoretical prediction,a new MAX phase V2SnC was synthesized experimentally for the first time by reaction of V,Sn,and C mixtures at 1000°C.The chemical composition and crystal structure of this new compound were identified by the cross-check combination of first-principles calculations,X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDS),and high resolution scanning transmission electron microscopy(HR-STEM).The stacking sequence of V2C and Sn layers results in a crystal structure of space group P63/mmc.The a-and c-lattice parameters,which were determined by the Rietveld analysis of powder XRD pattern,are 0.2981(0)nm and 1.3470(6)nm,respectively.The atomic positions are V at 4f(1/3,2/3,0.0776(5)),Sn at 2d(2/3,1/3,1/4),and C at 2a(0,0,0).A new set of XRD data of V2SnC was also obtained.Theoretical calculations suggest that this new compound is stable with negative formation energy and formation enthalpy,satisfied Born-Huang criteria of mechanical stability,and positive phonon branches over the Brillouin zone.It also has low shear deformation resistance c44(second-order elastic constant,cij)and shear modulus(G),positive Cauchy pressure,and low Pugh’s ratio(G/B=0.500<0.571),which is regarded as a quasi-ductile MAX phase.The mechanism underpinning the quasi-ductility is associated with the presence of a metallic bond.Qiang Xu Yanchun Zhou Haiming Zhang Anna Jiang Quanzheng Tao Jun Lu Johanna Rosén Yunhui Niu Salvatore Grasso Chunfeng Hu 2020Journal of Advanced Ceramics2020,9,4:8

3Efficacy of sequential treatment of HCT116 colon cancer monolayers and xenografts with docetaxel,flavopiridol,and 5-fluorouracil显示文摘瞄准:有 docetaxel, flavopiridol,或 5 氟尿嘧啶(5-FU ) 的稳固的肿瘤的临床的治疗经常遇到不受欢迎的副作用和药抵抗。在 modulating chemosensitivity 并且更好与 docetaxel, flavopiridol,或 5-FU 评估联合治疗的潜在的角色的目的理解他们怎么可能临床上被使用的这研究。方法:HCT116 结肠癌房间在几不同行政时间表在试管内与 docetaxel, flavopiridol,和 5-FU 被对待,顺序或同时。房间幸存被 MTT 试金测量。caspase-3 的活动被 caspase-3 试金决定,软琼脂殖民地试金被用来在软琼脂测试 HCT116 房间的菌落形成。我们也建立了异种皮移植模型扩大在试管内观察到一个在活体内系统。结果:当人的结肠癌 HCT116 房间为 flavopiridol 为另一 24 h 为 24 h 和 5-FU 跟随的 1 h 与 docetaxel 被对待时,最大的细胞毒性被发现。这顺序的联合治疗不仅与另外的联合治疗相比更强烈禁止肿瘤细胞生长而且显著地在软琼脂减少菌落形成并且扩充 HCT116 细胞的 apoptosis。docetaxel 定序以后由 flavopiridol 跟随了 1 h,以后在异种皮移植模型由 5-FU 跟随了 24 h,也导致了推迟的肿瘤生长和更高的幸存率。结论:当把 docetaxel 与 flavopiridol 和 5-FU 相结合时,这些结果强调一张行政时间表的重要性,提供对它在临床的试用的发展的基本原理解释。Jun GUO An-wu ZHOU Yu-cai FW Udit N VERMA Debu TRIPATHY Eugene P FRENKEL Carlos R BECERRA 2006Acta Pharmacologica Sinica2006,27,10:4
4Detection of DC series arc in more electric aircraft power system based on optical spectrometry显示文摘Series arcing faults have been recognised as a hazardous phenomenon in the power system of more electric aircraft(MEA),especially with the increasing voltage level and power supply.Instead of the electrical method,the optical method can be used as an approach to detect arc fault with the advantages of fast response and immunity to electromagnetic interference.It is the basis of optical arc detection to determine the distribution spectrum range of direct current(DC)arc fault.Aiming at series arc optical detection in the MEA DC system,a DC series arc test platform was established to measure the series arc spectrum.The spectrum was disassembled though empirical mode decomposition to extract characteristic wavelengths of arc light and denoised by means of wavelet decomposition and reconstruction(wavelet transformation)to reduce equipment noise.To resolve the baseline drift,the baseline of the arc spectrum measured was calculated and corrected based on Savitzky−Golay.The experimental results indicate that there are several series arc characteristic spectra of the MEA DC system,including 309.3 and 324.5 nm in the ultraviolet range.Moreover,the arc spectrum with different metals,copper and aluminium,were contrasted,indicating the arc spectral behaviour is related to the melting/boiling point and chemical properties of the anode material.The measurement of the series arc spectrum makes it more effective to apply optical detection in the MEA discharging faults diagnosis.Jun Jiang Mingxin Zhao Zhe Wen Chaohai Zhang Ricardo Albarracín 2020High Voltage2020,5,1:3

6A Capillary Electrophoresis Detection Scheme for Water-soluble Vitamins Based on Luminol-BrO^- Chemiluminescence System显示文摘A novel chemiluminescence detection scheme has been developed for detecting water-soluble vitamins following capillary electrophoresis (CE) separation. This detection was based on the inhibitory effect of vitamins on the CL reaction between luminol and BrO- in basic aqueous solution. Detection of vitamins was accomplished with a boratebased background electrolyte at pH 9.2. The luminol was used as a component of the separation carrier electrolyte.Wei DENG, Wei Ping YANG, Zhu Jun ZHANG*, Hou Jiang ZHOU College of Chemistry and Materials Science, Shaanxi Normal University, Xi抋n 710062 2003Chinese Chemical Letters2003,14,2:2
7Dissecting anxiety-related QTLs in mice by univariate and multivariate mapping显示文摘To detect genes underlying anxiety-related traits in mice,we performed univariate and multivariate QTL mapping analyses of phenotypes obtained from 71 mice of the BXD recombinant inbred (RI) strains (n=528 mice) and their parental strains (C57BL/6J and DBA/2J).Separate and joint mapping analyses were carried out using a linkage map composed of 506 simple sequence repeats (SSRs).The main QTL effects,interactions between pairs of QTLs (epistasis),and their environmental interactions were estimated.The results showed that anxiety-related traits were influenced by multiple QTLs (five main effect QTLs and three epistatic QTLs).Ten potential anxiety-related candidate genes within the QTL intervals on chromosomes 5,13 and 15 were identified.Some of these genes have been reported previously to be associated with the anxiety response.Based on our results,it is suggested that the multivariate QTL mapping approach improves the statistical power for detecting QTL and the precision of parameter estimation.Moreover,multivariate mapping can also detect pleiotropic QTL effects.ZHU ZhiHong ZHANG ChenHao WANG XuSheng COOK Melloni N WILLIAMS Robert LU Lu ZHU Jun 2012Chinese Science Bulletin2012,57,21:2
