包含钛的 mesoporous 材料(Ti-MCM-41 ) 被热水的合成获得。如此的材料是活跃催化剂让 dimethyl 盐和酚的 transesterification 生产 diphenyl 盐。在催化过程理解 Ti 的角色，有不同 Si/Ti 比率的 Ti-MCM-41 样品(从 5 ～ 100 ) 被准备，样品被红外线的光谱学，紫外可见的光谱学，和氨温度规划了的 Fourier 变换分析解吸附作用。Ti 被合并到 MCM-41 的框架并且形成了弱路易斯酸地点，这被结束。另外，当钛的数量增加了， Ti (IV ) 地点的数字增加了。X 光检查粉末衍射， N2 吸附解吸附作用和传播电子显微镜学结果证明 Ti-MCM-41 样…
Assuming that the lithiation reaction occurs randomly in individual small particles in the vicinity of the reaction front, a simple model of diffusioninduced dislocations was developed. The diffusion-induced dislocations are controlled by the misfit strain created by the diffusion of solute atoms or the phase transfor…
Ignition delay times of butanol isomers/n-heptane mixture were measured using a rapid compression machine at compressed pressures of 15, 20 and 30 bar, in the compressed temperature range of 650–830 K and equivalence ratio of 1.0. Sensitivity analysis and reaction fluxes analysis were performed using a detailed mechan…
This study investigated the hydrogenation of silicon tetrachloride(SiCl4) in microwave plasma. A new launcher of argon(Ar) and hydrogen(H2) plasma was introduced to produce a non-thermodynamic equilibrium activation plasma. The plasma state exhibited a characteristic temperature related to the equilibrium constant, wh…
