1Processing technique of target capsule's micro inflation hole with a scanning probe显示文摘To resolve inflation of inertial confinement fusion (ICF) target and encapsulation of micro inflation hole with adhesive, a scanning probe microscope (SPM) diamond microprobe was used as the cutting tool with SPM in contact mode. Some parameters influencing the quality of micro inflation hole, such as the scanning direction of the diamond tip, the scanning rate and the contact force are discussed. Accurate taper hole was achieved whose dimension and precision could meet the requirements of inflation and encapsulation technique of micro hole. The experimental results show that using SPM diamond microprobe as the cutting tool and with special processing technique, the precision machining of target capsule's taper inflation hole can be realized. A novel operative technology for filling high Z gas to target is provided.SUN Tao, YAN Yongda, GAO Dangzhong, TANG Yongjian, FU Yibei & DONG ShenPrecision Engineering Research Institute, Harbin Institute of Technology, Harbin 150001, China Research Centre of Laser Fusion, Chinese Academy of Engineering Plysics, Mianyang 621900, China Institute of Nuclear Physics and Chemistry, Chinese Academy of Engineering Physics, Mianyang 621900, China 2004Science China(Technological Sciences)2004,47,1:7
2Preparation of Zn/TiO_2 powder and its photocatalytic performance for oxidation of P-nitrophenol显示文摘Zn-doped TiO_2 catalysts were prepared using a sol-gel method and characterized by XPS,UV-Vis,BET, XRD in this study.Under the irradiation of simulant sunlight,the photocatalytic activity for the degradation of p-nitrophenol was studied too.After irradiation for 2.5 h,the degradation percentage of p-nitrophenol could rise to more than 80%.The results showed that the spectrum absorption band edge of Zn/TiO_2 powder does not broaden obviously comparing with pure TiO_2 powder.Zinc exists as Zn (Ⅱ).When calcined at 973 K,there is a new phase as ZnTiO_3 in Zn/TiO_2 catalyst.The order of photocatalytic activity of Zn/TiO_2 catalysts calcined at different temperatures for p-nitrophenol is 773 K>673 K>873 K>573 K>973 K and the photocatalytic activity of Zn/TiO_2 catalyst cal- cined at 773 K is better than TiO_2 catalysts heated at the same temperature,and outclasses that of commercial TiO_2 catalyst.It also showed that the photocatalytic degradation of p-nitrophenol follows first-order kinetics under the irra- diation of simulant sunlight.LIU Xiuhua XU Yunshu ZHONG Zhijing FU Yibei DENG Yi 2007Nuclear Science and Techniques2007,18,1:2

7Prediction on Phase Stabilities of the Zr-H System from the First-Principles显示文摘Basic fundamentals governing the hydrogenation of Zr and its alloys have both theoretical and practical importance.In this work,first-principles calculations have been performed to evaluate the relative stabilities of various possible phases in ZrH_(x)(x=1-2)under different temperatures and pressures.It was predicted that fct-γandεphases with various different H-atom configurations can be energetically favorable for ZrH_(x)(x=1,1.25 and 1.5),while ZrH_(1.75) and ZrH_(2) prefer fct-ε phase only.Fcc-δ phase is less favored in energy at any H concentrations,but can be mechanically stable in some cases.The thermodynamically stable and metastable phase stability diagrams were then constructed for a wide temperature and H concentration range,to predict the environment-dependent formation of ZrH_(x) during hydrogenation.Miao Chen Wu Qin Yixuan Hu Yiren Wang Yong Jiang Xiaosong Zhou Shuming Peng Yibei Fu 2021Acta Metallurgica Sinica(English Letters)2021,34,4:0
8Characteristics and expression of the TCP transcription factors family in Allium senescens reveal its potential roles in drought stress responses显示文摘Allium senescens,is an important economic and ecological grassland plant with drought-resistant characteristics.A TCP protein transcription factor is important in the regulation of plant development and adverse responses.However,the mechanism by which TCP transcription functions in drought resistance in Allium senescens is still not clear.Here,we obtained a total of 190,305 transcripts with 115,562 single gene clusters based on RNA-Seq sequencing of Allium senescens under drought stress.The total number of bases was 97,195,096 bp,and the average length was 841.06 bp.Furthermore,we found that there were eight genes of the TCP family that showed an upregulated expression trend under drought stress in Allium senescens.We carried out an investigation to determine the evolution and function of the AsTCP family and how they produce an effect in drought resistance.The 14 AsTCP genes were confirmed and divided into class I and class II containing CIN and CYC/TBI subfamilies,respectively.We also found that the expression of AsTCP17 was remarkably upregulated with drought treatment.Besides,the transformation of AsTCP17 in Arabidopsis revealed that the protective enzymes,namely polyphenol oxidase(POD)and superoxide dismutase(SOD),were increased by 0.4 and 0.8 times,respectively.Chlorophyll content was also increased,while the H2O2 and malondialdehyde(MDA)contents were decreased.Staining assays with 3,3′-diaminobenzidine(DAB)also suggested that the AsTCP17 downregulates reactive oxygen species(ROS)accumulation.In addition,overexpression of the AsTCP17 affected the accumulation of drought-related hormones in plants,and the synthesis of ABA.The expression of AtSVP and AtNCED3,related ABA synthesis pathway genes,indicated that the level of expression of AtSVP and AtNCED3 was obviously enhanced,with the overexpression of line 6 showing a 20.6-fold and 7.0-fold increase,respectively.Taken together,our findings systematically analyze the AsTCPs family at the transcriptome expression level in Allium senescens,and we also demonstrated that AsTCP17 protein,as a positive regulator,was involved in drought resistance of Allium senescens.In addition,our research contributes to the comprehensive understanding of the drought stress defense mechanism in herbaceous plants.XIAOHONG FU JIE ZHAO DANDAN CAO CHENGXING HE ZIYI WANG YIBEI JIANG JIANFENG LIU GUIXIA LIU 2023BIOCELL2023,47,4:0
9Photocatalytic degradation of 2,4,6-trinitrotoluene显示文摘A Pt/TiO2 photocatalyst was used in the photocatalytic degradation of 2,4,6-trinitrotoluene (TNT) under the irradiation of the simulated sunlight. The results show that the destruction of TNT is faster and more complete with the photocatalyst. The photocatalytic degradation of TNT follows first order kinet-ics. The transformation of nitryl groups of TNT molecules into nitrite and nitrate ions may be acceler-ated in the presence of the Pt/TiO2 photocatalyst. Compared with that without the catalyst, the concentration of nitrate ions was improved 32.3 times within 2.5 h.LIU XiuHua FU YiBei WANG HeYi ZHONG ZhiJing XU YunShu 2008Science China Chemistry2008,51,10:0
