新工科项目“地方(行业)高校化学类专业应对产业变化的升级改造研究与实践”的实施

This "emerging engineering education (3E)" project "Upgrade and Practice of Chemistry-related Majors of Local and/or Specialized University Responding to the Industry Changes" was supported by the Ministry of Education. To aim at the issue of how to upgrade the chemistry-related majors of a local and/or specialized university responding to industry changes, an investigation on local regional economy and industry changes was carried out, the capability requirements of 3E for talents were analyzed, and the training objectives, graduation requirements as well as the new teaching models were also studied for the major to meet the future requirements. The practical experience for 3E construction of chemistry-related majors by selected universities was suggested.

Synthesis of Obyanamide, a Marine Cytotoxic Cyclic Depsipeptide

Obyanamide 1 is a cyclic depsipeptide that was recently isolated from the marine cyanobacterium Lyngbya confervoides by Moore and co-workers1. This compound displayed a potent inhibitory effect on both KB and LoVo cells in vitro. Several structural analog…     

轻希土硫氰酸盐与2, 3, 11, 12, -四苯基-1, 4, 7, 10, 13, 16-六氧-2, 11-十八环二烯配合物的合成及XPS研究

合成了六种轻希土硫氰酸盐与标题不饱和冠醚的新固体配合物,进行了元素分析,摩尔电导率、DTA、UV、IR和XPS等表征.对Ln(NCS)₃·L和Ln(NCS)₃的XPS研究中,得到它们组成原子芯能级电子(Ln3d_5/2,Ols,Nls,S2p)的结合能信息;观察到除Y3d_5/2外Ln3d_5/2(Ln=La、Ce、Pr、Nd、和Sm)的伴峰结构,Ln3d_5/2结合能与原子序数呈线性关系,并推断类似化合物Pm³d_5/2结合能在1035eV附近.     

低温原子化石墨炉原子吸收法测定环境和生物样中的镉

本文描述了以氩/氢混合气体作保护气体,测定环境和生物样品中痕量镉的石墨炉原子吸收法。实验证明,与纯氩气作保护气体相比较用氩/氢混合气体作保护气体,能够降低镉的原子化温度(100℃),并且减少基体物质如MgCl_2和NaClO_4的干扰。这种改善氯化物和高氯酸盐基体干扰的机理,主要是由于氢的存在与基体中的氯形成高离解能的氯化氢,从而避免了通常在镉原子化之前形成易挥发的氯化镉而损失。用本方法测定了七种标准参考物质,结果与标准值一致,证明方法是可靠的。     

圆二色谱中的激子手性法在有机化学中的应用
