The preparation and applicability of solid phase microextraction (SPME) fibers coated with a sol-gel organically modified silica based on 3-aminopropyltrimethoxysilane and polydimethylsiloxane (APTMS/PDMS) are described here. Micrographs of the coated fibers revealed a rugous surface; the thickness of the coating was estimated to be less than 30 microm. The APTMS/PDMS fibers were tested with sy...

Bioactive glasses are able to bond to bone and stimulate the growth of new tissue while dissolving over time, which makes them ideal materials for regenerative medicine. The advent of mesoporous glasses, which are typically synthesized via sol-gel routes, allowed researchers to develop a broad and versatile class of novel biomaterials that combine superior bone regenerative potential (compared ...

Tin oxide nanostructures, un-doped and Zn-doped, have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) and zinc acetate (Zn(O2C2H3)2) were used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped and Zn-doped SnO2 sol was prepared after continuous stirring and refluxing at ...

Tin oxide nanoparticles have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) was used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped SnO2 sol was prepared after continuous stirring and refluxing at 40C. Thin films, prepared from SnO2 sol, have also been deposited on g...
