On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.
综合催化剂的表征和活性评价得出:当镍基催化剂上氧化镍以结晶态存在,经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐,丁二酸酐难以进一步加氢为γ-丁内酯;当镍基催化剂上氧化镍以簇团形式存在,与载体之间有适当的相互作用时,经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯;若催化剂上氧化镍既有结晶态又有簇团形式时,随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。

Analysis of nuclear extracts of human cells has indicated a similar excision repair mechanism for nick-directed mismatch correction in higher cells, and several reconstituted systems that rely on purified human proteins have been described, such as hMutSα、hMutSβ、hMutLα. Recently, scientists discovered that nickel could be inhibitors of DNA repair. Nickel can greatly enhance the mutagenicity and genotoxicity of compounds in cigarette by inhibiting the nucleotide excision repair pathway in human cells. We have confirmed that nickel could inhibit MMR of E. coli and human and presumed that nickel inhibited repair before MutH incision of the MMR in E. coli. However, there is no evidence of mechanism of nickel inhibiting MMR in human cells.
镍是存在於香菸中的微量金属,近年来有学者发现镍是DNA修复反应的抑制剂,长期抽烟的人会容易因为香菸中化合物攻击DNA而引起突变,进而引起肺癌,而镍会抑制核苷酸移除修复系统(nucleotide excision repair;NER),所以使得体内的DNA损伤无法修复;过去实验室已经证实大肠杆菌的核酸配对错误修复系统会受到镍等重金属的抑制,并且推测出镍的抑制反应是抑制在修复反应的上游nicking的步骤;另外,也证实了人类的核酸配对错误修复系统也会受到镍的抑制,然而还没研究证实会抑制在核酸配对错误修复反应的哪个步骤。

The study of vertical channel with high field effect mobility by Ni induced lateral crystallization, which can form larger grains on channel regions and reduce grain boundary defects. We detect the method of Ni induced lateral crystallization through high field effective mobility, but that accumulates too much Ni on floating N+ region and causes defects and metal contamination. As Ni is used to form silicde and then proceed to low temperature annealing, we can observe the floating region that has no Ni acumination regions or contaminations. This aids us in obtaining good electronic performance of this device, not only the remote field effective mobility but also the vast improvement of sub-threshold swing and on/off currents.
接著,是延续垂直通道的研究,希望能有效的提升电子迁移率,因此以镍金属诱导横向结晶的方式使通道形成较大的结晶,减少矽晶粒之间的缺陷,而在初步的研究,发现以镍金属直接诱导横向结晶的方式,经由低温长时间回火之后,由於镍金属扩散的关系,完成诱导结晶之后,有过多的镍金属聚集在顶部参杂的中间区域,而造成过多的缺陷累积,虽然电子迁移率有效的提升,但整体的电性并不如预期,因此提出先形成镍金属矽化物后,将未反应的镍金属或金属氧化物去除之后,再进行镍金属矽化物诱导横向结晶处理,经由结果观察得知在顶部掺杂区域部分没有明显的镍金属累积或污染,并且得到很好的整体电性,除了电子迁移率有效提升之外,次临界特性以及导通电流都能有效改善。
