Hosting ability of mesoporous micelle-templated silicas toward organic molecules of different polarity

Article Abstract:

Spin probe water solutions were adsorbed onto differently treated micelle-templated silicas (MTS) of different pore sizes to analyze the hosting ability of the MTS surface toward different organic molecules. The MTS synthesis was performed at 388 K by self-assembly of inorganic silica and micelles of cetyltrimethylammonium bromide (CTAB) to which different amounts of 1,3,5 trimethylbenze (TMB) were added at different TMB/CTAB ratios.

Mechanism of the hydrosilylation reaction of alkenes at porous silicon: Experimental and computational deuterium labeling studies

Article Abstract:

A study on the mechanism of the formation of Si-C bonded monolayers on silicon by reaction of 1-alkenes with hydrogen-terminated porous silicon surfaces is conducted by both experimental and computational means. Highly deuterated porous silicon and FTIR spectroscopy is used to provide evidence for this mechanism by identifying the IR bands associated with the C-D bond formed in the proposed propagation step.
