The adsorption kinetics of CO on the surface of Pd(100) modified by sulfur has been investigated. On the clean Pd(100) surface, CO .precursor state molecules are formed during CO adsorption. With adding sulfur adatoms on Pd(100) surface, the lifetime of precursor molecules is reduced. When sulfur coverage on Pd(100) surface is larger than 0.16, there will be no precursor molecules formed. The influence of sulfur adatoms on Pd(100) surface is stronger than that on Ni surface.

研究了CO在硫改性Pd(100)表面上的吸附动力学。在清洁Pd(100)表面上吸附CO时产生前兆态吸附分子,随着硫的加入,缩短了前兆态分子的寿命。当表面上硫覆盖度大于0.16时,基本上不形成CO前兆态分子。硫对Pd表面的这种影响比对Ni表面大。

The studies on the thermal deposition of transition metal coordination compounds have been directly motivated by the development of organometallic chemical vapor deposition (OMCVD) technique. Among these compounds Cu(II) acetylacetonate, Cu(acac)_2, is a potentially important precursor for the deposition of Cu film and preparation of high T_e superconducting films. However, little information about the kinetics of thermal decomposition of this compound is available. In this paper we report a kinetic study on the deposition of copper film by decomposing Cu(acac)_2. A CW CO_2 laser is used to heat a quartz substrate and to induce thermal decomposition on the surface. The deposition rate is measured in situ by monitoring the transmittance of the Cu film on the substrate with a He-Ne laser. As the CO_2 laser beam only heats the quartz window, the temperature of the reaction cell can be controlled. The dependenc(?) of the deposition rate on the laser intensity is determined at a given vapor pressure of Cu (acac)_2 and a laser intensity threshold has been observed. Above the threshold the deposition rate increases linearly with laser intensity in the low intensity region. The laser-induced temperature rise of the substrate and the deposition rate constant have been calculated. The Arrhenius plot is linear and the activation energy for thermal deposition of Cu(acac)_2 is 181±19kJ·mol~(-1). In higher laser intensity region the deposition rate becomes independent on the laser intensity, but is a function of the vapor pressure of Cu(acac)_2. The decomposition of Cu(acac)_2 has been found to be first order. The rate-controlling step seems to be the surfaoe reaction on the substrate at low laser intensity, while the transport of precursor molecules is crucial at high laser intensity.

金属有机化合物气相化学沉积(OMCVD)形成铜膜常用的母体化合物是铜(II)的β-二酮类配合物.本文首次采用CW二氧化碳激光研究二(乙酰丙酮根)合铜(II)[Cu(acac)_2]在石英基片上沉积铜膜过程的动力学.沉积速率由探测光束(He-Ne激光)通过铜膜时透过率的衰减进行实时测量.实验表明,二氧化碳激光辐照功率对沉积速率有明显的影响,并存在一阈值.在较低功率区域内,Cu(acac)_2在表面上热分解反应是沉积速率控制步骤.由Arrhenius关系已求得表面热分解反应的表观活化能为181 kJ/mol.在较高功率的区域内,沉积速率趋于恒定,可以认为此时气相Cu(acac)_2分子向表面扩散的传质过程是沉积速率控制步骤.沉积速率随外加惰性气体压力增加而下降,并测得与Cu(acac)_2蒸气压力之间呈一级反应关系.对Cu(acac)_2热分解机理作了讨论.

Fibrinogen is a large dimer molecule composed of three nonidentical polypeptide chains. In the presence of thrombin, it converts to fibrin by cleavage of fibrinopeptide A and fibrinopeptide B, Mr 1 800 each, and forms crossliked fibrin by γ-γ cross links mediated by factor XⅢ. This conversion results in retention of 98% of the primary structure of the precursor molecule. Therefore, it is difficult to obtain a specific antibody to discriminate fibrinogen and fibrin. In this study, we tried to produce the...

Fibrinogen is a large dimer molecule composed of three nonidentical polypeptide chains. In the presence of thrombin, it converts to fibrin by cleavage of fibrinopeptide A and fibrinopeptide B, Mr 1 800 each, and forms crossliked fibrin by γ-γ cross links mediated by factor XⅢ. This conversion results in retention of 98% of the primary structure of the precursor molecule. Therefore, it is difficult to obtain a specific antibody to discriminate fibrinogen and fibrin. In this study, we tried to produce the monoclonal antibody specific for the conformational epitope expressed only on fibrin but not on fibrinogen.

用XL-FN颗粒、D-D、FN单体等作为免疫原获得一组小鼠单克隆抗体。除了3个与FG有交叉反应,其余均只与XL-FN和/或其片段反应。其中SZ-58、SZ-60及SZ-63与血浆凝块的结合反应不受血浆或全血影响。在免疫印迹电泳中,SZ-63主要识别D-D,而SZ-58不识别任何区带。SZ-58、SZ-60可抑制血浆凝固,并对ADP诱导的血小板聚集有程度不同的抑制作用。SZ-60可与固相化的FG结合而与溶解态的FG无结合反应。结果提示,SZ-58、SZ-60、SZ-63对XL-FN反应的特异性较高,因此可应用于体内血栓显像而SZ-63同时又可应用于D-D检测。
