A novel calix[4] open-chain crown ether (p-tert-butylcalix[4]arene-1,3-bis(allyloxyethy) ether)-modified, organic-inorganic hybrid silica-based monolithic column possessing vinyl ligands for CEC is described. The monolithic silica matrix containing a vinyl functionality was synthesized by in situ cocondensation of tetramethoxysilane (TMOS) and vinyltrimethoxysilane (VTMS)

A method for the preparation of inorganic superhydrophobic silica coatings using sol-gel processing with tetramethoxysilane and isobutyltrimethoxysilane as precursors is described. Incorporation of isobutyltrimethoxysilane into silica layers resulted in the existence of hydrophobic isobutyl surface groups, thereby generating surface hydrophobicity.

The temperature effects during the sol-gel process and ageing of the silica-based monolith on the structure and separation efficiency of the capillary columns (100microm i.d., 150mm) for HPLC separations were studied. The tested columns were synthesized from a mixture of

A simple capillary flow porometer (CFP) was assembled for through-pore structure characterization of monolithic capillary liquid chromatography columns in their original chromatographic forms. Determination of differential pressures and flow rates through dry and wet short capillary segments provided necessary information

Bio-Inspired “Green” Synthesis of Nanomaterials and their Applications

Silica is a very popular inorganic nanomaterial used in a wide range of applications including fillers for rubber, catalyst supports, separation media, carriers in food and agriculture, and abrasive/anticaking agents in cosmetics. It is also widely believed to be an important material for biomedical applications for following reasons.

Vistas in Current Magnetic Materials Research

Magnetism and magnetic materials have been of scientific interest for over 1,000 years. More recently, fundamental investigations have focused on exploring the various types of magnetic materials and understanding the magnetic effects created by electric currents.
