| 1 | Design and Synthesis of 6α-Corticosteroid Haptens and Their Bovine Serum Albumin (BSA) Conjugates显示文摘The site of attachment of protein carrier to corticosteroids has great influence on the specificity of produced antibody. In order to obtain highly specific and accurate antibodies for bioimmunoassay determination of cortisol, different tether lengths of 6-corticosteroid haptens and their BSA conjugates were designed and synthesized. | Pi SUN*, Norihiro KOBAYASHI, Junichi GOTO Graduate School of Pharmaceurical Sciences, Tohoku University, Aobayama, Aoba-ku, Sendai 980-8578, Japan | 2003 | Chinese Chemical Letters2003，14，3： | 3 |
| 2 | Study on Solubility of Nb_2O_5 in KOH Solution and Alkali Leaching of Niobite显示文摘Solubility of Nb 2O 5 and leaching behaviors of Nb and Ta from niobite in KOH solution have been investigated in order to develop an alkali hydrothermal leaching process of Nb and Ta. The solubility of Nb 2O 5 was measured in the range of 40 ℃ to 200 ℃ at various molar ratios of K 2O to Nb 2O 5 ( n (K 2O)/ n (Nb 2O 5)). It has been found that Nb 2O 5 shows the maximum solubility at the solution composition of n (K 2O)/ n (Nb 2O 5)=4/3 at a given temperature; the rise of temperature increases the solubility of Nb 2O 5 below 120 ℃, but decreases it above 120 ℃. The leaching behaviors of Nb and Ta were studied in the range of 150 ℃ to 250 ℃ and 0.1 MPa to 5 MPa. With the rise of temperature, the leaching degree increases when the leaching temperature is below 200 ℃, but it decreases when the leaching temperature is above 200 ℃. The maximum leaching degree is about 90% at 200 ℃. It was proved that the alkali hydrothermal leaching process is effective for the recovery of Nb and Ta from niobite concentrate. | ZHOU Kang gen 1,TOKUDA Masanori 2 (1.Metallurgical Separation Science and Engineering Lab., Central South University, Changsha 410083, China 2.Tohoku University, Sendai 980 77, Japan) | 2000 | Journal of Central South University2000，12，4： | 2 |
| 3 | Photocatalytic intercalated material based on HLaNb_2O_7 as host and Cd_(0.8)Zn_(0.2)S as guest显示文摘A novel photocatalytic material (Pt,Cd0.8Zn0.2S)/HLaNb2O7 was fabricated by successive intercalation and exchange reactions. The (Pt,Cd0.8Zn0.2S)/HLaNb2O7 possessed a gallery height less than 0.5 nm and showed a broad absorption with wavelength over 370―500 nm. Using (Pt,Cd0.8Zn0.2S)/HLaNb2O7 as catalyst, the photocatalytic H2 evolution was more than 160 cm3·h-1·g-1 in the presence of Na2S as a sacrificial agent under irradiation with wavelength more than 290 nm from a 100-W mercury lamp. Furthermore, the catalyst showed photocatalytic activity even under visible light irradiation. | WU JiHuai1,CHENG YingHan1, LIN JianMing1, HUANG YunFang1, HUANG MiaoLiang1, LI YiBin1, YIN Shu2 & SATO Tsugio2 1 The Key Laboratory for College of Materials Science and Engineering, Huaqiao University of Fujian Higher Education, Institute of Materials Physical Chemistry, Huaqiao University, Quanzhou 362011, China 2 Institute of Multidisciplinary Research for Advanced Materials, Tohoku University, Sendai 980-8577, | 2007 | Science China Chemistry2007，50，4： | 2 |
| 4 | Fluid Flow Behavior of Liquid in Cylindrical Vessels Stirred by One or Two Air Jets显示文摘Based on the two-phase model (Eulerian-Eulerian model), the three dimensional fluid flow in water and that liquid steel systems stirred by one or two multiple gas jets are simulated. In the Eulerian-Eulerian two-phase model, the gas and the liquid phase are considered to be two different continuous fluids interacting with each other through the finite inter-phase areas. The exchange between the phases is represented by source terms in conversation equations. Turbulence is assumed to be a property of the liquid phase. A new turbulence modification - model is introduced to consider the bubbles movement contribution to and . The dispersion of phases due to turbulence is represented by introducing a diffusion term in mass conservation equation. The mathematical simulation agrees well with the experiment results. The study results indicate that the distance of two nozzles has big effect on fluid flow behavior in the vessel. Using two gas injection nozzles at the half radii of one diameter of the bottom generates a much better mixing than with one nozzle under the condition of the same total gas flow rate. | Lifeng Zhang, Shoji Taniguchi, Kaike Cai, Ying Qu ( Department of Metallurgy Graduate School of Engineering, Tohoku University, Sendai 980-579 Japan Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China) | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，3： | 2 |
| 5 | Adlayer structure of TCNQ molecules on Cu(111): An in situ STM study显示文摘In situ electrochemical scanning tunneling microscopy (STM) was employed to examine tetracyano-quinodimethane (TCNQ) layer adsorbed on Cu(lll) electrode surface in 0.1 mol/L HC1O4 solution. The TCNQ molecules are found to form highly-ordered long range ad-layer with a (4×4) symmetry. Each TCNQ molecule is adsorbed on Cu(111) surface in flat-lying orientation. The molecules are preferentially aligned with their long axes inthe [ 121 ] direction. A structural model is proposed for the adlayer. | WAN Lijun & Kingo ItayaInstitute of Chemistry, Chinese Academy of Sciences, Beijing 100080, China Department of Applied Chemistry, Graduate School of Engineering, Tohoku University, Sendai, Japan | 2001 | Chinese Science Bulletin2001，46，5： | 2 |

| 13 | Giant Volume Magnetostriction Caused by Itinerant Electron Metamagnetic Transition and Pronounced Invar Effects in La(Fe_xSi_(1-x))_(13) Compounds显示文摘A first-order itinerant electron metamagnetic (IEM) transition above the Curie temperature Tc for ferromagnetic La(FexSi1-x)13 compounds has been confirmed by applying magnetic field. The volume change just above TC for x=0.88 is huge of about 1.5%, which is caused by a large magnetic moment induced by the IEM transition. These compounds have a possibility for practical applications as giant magnetostrictive materials. Pronounced Invar effects bring about a negative thermal expansion below TC, closely correlated with the negative mode-mode coupling among spin fluctuations. | K.Fukamichi and A.Fujita (Department of Materials Science, Graduate School of Engineering, Tohoku University, Aoba-yama 02, Sendai 980-8579, Japan) | 2000 | Journal of Materials Science & Technology2000，16，2： | 1 |
