Silica/quercetin sol–gel hybrids as antioxidant dental implant materials
The development of biomaterials with intrinsic antioxidant properties could represent a valuable strategy for preventing the onset of peri-implant diseases. In this context, quercetin, a naturally occurring flavonoid, has been entrapped at different weight percentages in a silica-based inorganic material by a sol-gel route. The establishment of hydrogen bond interactions between the flavonol an...
متن کاملSulphuric Acid Adsorbed on Silica Gel. A Remarkable Acetylation Catalyst
Sulphuric acid adsorbed on silica gel is a practical and useful catalyst for acetylation of varius alcohols, Phenols and amines.
متن کاملSilica gel medium for enumeration of petroleumlytic microorganisms in the marine environment.
A silica gel medium was developed for the enumeration of petroleumlytic microorganisms in the marine environment. The medium was satisfactorily used for the investigation of the vertical distribution of bacteria in seawater from the surface to 1,000 m depth of western north Pacific central water as well as the neritic region of Japan.
متن کاملManganese and Cobalt Salts of Para-Amino-Benzoic Acid Supported on Silica Gel as Oxidizing Catalysts
Para-Aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. A mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. Reactions are clean and the catal...
