Synthesis of a conducting SiO2-carbon composite from commercial silicone grease and its conversion to paramagnetic SiO2 particles

Article Abstract:

A one-stage, catalyst-free, efficient and simple synthetic method is described by using a commercially available nonconventional single precursor, silicone grease, for the production of high surface area carbon silica hybrid materials. The annealing of the as-prepared SiO2-carbon composite at 500 degree centigrade in air led to the formation of white paramagnetic SiO2 particles.

Fabrication and magnetic properties of Ni nanospheres encapsulated in a fullerene-like carbon

Article Abstract:

A simple, efficient, and economical synthetic technique, which produces fullerene-like Ni-C (graphitic) core-shell nanostructures at a relatively low temperature, is reported. The magnetoresistance (MR) property of Ni nanospheres encapsulated in a fullerene-like carbon is measured, which shows large negative MR, of the order of 10%.

Thermal decomposition of commercial silicone oil to produce high yield high surface area SiC nanorods

Article Abstract:

The synthesis of high surface area [beta]-SiC nanorods by thermal decomposition of commercial silicone oil at a relatively low reaction temperature in a closed Swagelok cell is described. No catalyst, template or solvent is used in this technique and this synthesis is readily scaled-up.
