中国化学会第30届学术年会-第十八分会：电子结构理论方法的发展与应用

作者： Jian-Fu Wang qian-qian li Yong-Fan Zhang Xin Huang Bin Wang Department of Chemistry Fuzhou University

Through an extensive literature survey, we found that transition metal sulfides such as molybdenum sulfides and niobium sulfides have a lot of advantages and the widespread application. In particular, molybdenum sulfides have been used as efficient catalysts in hydrodesulfurization(HDS) and hydrodenitrogenation(HDN). In the current work, we carried out an extensive computational investigation of the structural and electronic properties of heteronuclear metallic sulfide clusters NbMoS via B3LYP density functional theory(DFT) and coupled cluster [CCSD(T)] theory. Our study reveals that the ground-state of neutral NbMoS is the doublet(C A’) with two terminal S atoms, two bridging S atoms and one bridging S units(Fig. 1A). For the anionic species NbMoS, it shows disparate geometry(Fig. 1B) which is predicted to be closed-shell( C A’) with four terminal S atoms and two bridging S atoms. We found that the Nb-Mo bond length increases from 2.862 ? to 3.203 ? as one more electron is added into NbMoS. It may lead the bridging S units to be broken. The anionic photoelectron spectrum(Fig. 1C) of NbMoS was simulated based on the calculated vertical detachment energies(VDEs). The first vertical detachment energy(VDE) is calculated to be 4.69 e V using generalized Koopmans’ theorem. Molecular orbital analyses were performed to elucidate the chemical bonding in NbMoS clusters.

蛋白质乙酰化是一种普遍存在于真核与原核生物中且可逆的翻译后修饰方式,由乙酰基转移酶和去乙酰化酶共同调控,参与了转录、新陈代谢、细胞信号转导、细胞凋亡等多个生物学过程。随着检测技术的不断发展,目前已发现了大量的组蛋白及非组蛋白的乙酰化修饰,对其功能的研究也取得一定的进展。本文从乙酰化修饰研究进程出发,对植物病理学领域,包括植物抗病相关过程、植物病原菌和生防菌三个方面的乙酰化研究进展进行总结归纳,并对今后乙酰化修饰研究所需解决的问题进行了展望和讨论。

三峡库区内淤积泥沙均属细颗粒泥沙范畴,运动规律较为复杂。依靠传统泥沙理论即以挟沙力为判断标准,所得冲淤情况与实际观测情况有所出入,需进行进一步研究。在三峡库区典型淤沙河段——皇华城河段现场观测的基础上,通过水槽试验研究库区细颗粒泥沙的运动特点,对不同水深流速下细颗粒泥沙的运动状态进行归类整理,发现其淤积过程可根据水深与流速的不同划分为3个区域,即冲刷区、相对平衡输送区及淤积区,并指出用流速作为判断细沙输移状态的标准更符合库区实际冲淤情况。
