Mechanism and nanosize products of the sol-gel reaction using diphenylsilanediol and 3-methacryloxypropyltrimethoxysilane as precursors

Article Abstract:

A first-principles calculation and small-angle neutron (SANS) are used to investigate the mechanism and the nanosize products of the sol-gel reaction with diphenylsilanediol (DOP) and 3-methacryloxypropyltrimethoxysilane (MEMO) precursors in synthesizing a hybrid waveguide material. SANS measurements determines that the final products from sol-gel reaction are on the nanometer scale, at sizes from 1.76 to 2.36.

Interaction of a transition metal atom with intrinsic defects in single-walled carbon nanotubes

Article Abstract:

Density functional theory (DFT) calculations are used to investigate the interaction of a transition metal atom with defects in single-walled carbon nanotubes (SWNTs). The results have provided information on the nature of the interaction of the transition metal with defects in SWNTs, which is useful for the fabrication of nanosized transition metal particles supported on carbon nanotubes.

Dissociative adsorption of methylsilane on the Si(100)-2 x 1 surface

Article Abstract:

Density functional theory calculations are used to examine the mechanisms of dissociative adsorption of methylsilane on the Si(100)-2 X 1 surface. The findings indicate that the product of Si-H dissociation is the dominating dissociative product whereas methylsilane is a good candidate for the growth of SiC films.
