甲酸－异丙醇体系分离蛋白质时甲酸的作用研究

 本文在反相高效液相色谱上，用甲酸－异丙醇体系作流动相，研究了甲酸浓度变化对蛋白质分离的影响。结果表明当甲酸浓度增加时，蛋白质的保留时间减小和计量置换模型之值的降低反映了甲酸在这个体系中具有洗脱剂的作用。甲酸使蛋白质在流动相中的溶解度增大，具有离子对试剂的作用。在这个体系中甲酸还具有破坏蛋白质结构的功能。

GIF S-亚硝基化的一些见解

Neural growth inhibitory factor （GIF）, a member of metallothionein family （metallothionein-3, MT3）, was well known by its distinct neural growth inhibitory activity, which is not shown by other MT isoforms. However, till now, people still did not know clearly how GIF exerts its biological functions. Since it has been reported that GIF might serve as NO scavenger and was related to the release of zinc, our study was focused on the interaction of GIF and NO. By studying the reactions of human GIF and human MTlg with SNOC-a type of NO donor, it was found that GIF was more reactive than MT-lg toward SNOC. In order to further figure out if the high reactivity of GIF in this reaction resulted from the acid-base catalysis, several mutants were constructed： E23K, E41G/E43A, E23K/E41G/E43A. By studying their basic properties and the reactions toward SNOC, it was found that the S-nitrosylation of GIF was not only related to the acid-base catalysis, but also to the accessibility of metal-thiolate clusters.

糠醛脱羰用Pt-K/Al2O3催化剂制备研究--浸渍溶剂的影响

选用丙酮，乙醇、水、乙酸等4种不同溶剂，采用浸渍法制备Pt-K/Al2O3催化剂，电镜分析表明，Pt的分布，分散度与溶剂存在一定关系，且由于助剂K的添加，使Pt浓度的最大值并不在外表面，而在外表面之下；Pt-K/Al2O3的催化性能与Pt的分布，分散度及Pt/K比值有一定关系，当以乙醇为浸渍溶剂时，制备得到的催化剂催化性能最好。     

溶剂化金属原子浸渍法制备Pd-Cu/γ-Al2O3低温CO氧化催化剂

Nano-particle Pd/γ-Al₂O₃ monometallic and Pd-Cu/γ-Al₂O₃ bimetallic catalysts were prepared by solvated metal atom impregnation (SMAI) method. The results of XRD measurement indicated that Pd- Cu alloy was formed in the bimetallic catalysts and the crystalline particle size of the alloy increased as Cu contents increased with av-erage diameters < 6.0nm for all the samples. XPS and Auger spectra showed that Pd was in zero- valent state, Cu existed mainly in zero- valent state and partially in monovalent state Cu⁺. The Pd/γ-Al₂O₃ and Pd-Cu/γ-Al₂O₃ catalysts exhibited higher activity for CO oxidation at low temperature. The activity of Pd-Cu/γ-Al₂O₃ bimetallic catalyst was higher than that of Pd/γ-Al₂O₃ monometallic catalyst. The Pd-Cu/γ-Al₂O₃ catalyst with Pd/Cu atomic ratio of 1∶1 showed the highest activity.     

氧化铈对氯化锰表面氧脱附与恢复性能的影响

采用ＴＰＤ－ＭＳ技术研究了Ｍｎ－Ｃｅ－Ｏ体系催化剂的表面氧脱附（供出）和恢复性能，并以甲醇氧化反应为探针考察了催化剂在不同气氛下的氧化活性。结果表明，氧化铈的存在并不影响氧化锰Ｏ２－ＴＰＤ特征峰的位置，但氧化锰表面的吸附氧数量明显增加，氧化锰表面吸附氧的恢复能力随氧化铈含量的增加而增大。催化剂对甲醇的氧化活性与其表面吸附氧数量有很好的对应并系。催化剂表面氧恢复能力越大，对甲醇的氧化活性受气影响越小
