Experience accumulated over a number of years in developing of methods of immobilization of galactose oxidase from Fusarium graminearum on parent and modified silica matrices is analyzed. Sturdy adsorption of galactose ...

Urea- and thiourea-containing trialkoxysilanes were prepared with a high yield and purity. By sol-gel processing of these precursors the new functionalized xerogels were synthesized and characterized by FTIR, elemental ...

Bimodal mesoporous silicas and materials MCM-41 type were synthesized with the use as a template cationic surfactants distinguished by a length of the alkyl chain. Fumed silica, tetraethyl orthosilicate as well as of mixture ...

A study has been conducted on adsorption of semisynthetic flavonoid venoruton on the surface of highly dispersed silica (HDS) modified with polyvinylpyrrolidone (PVP). It has been found that an adsorption value of venoruton ...

A study of glucose oxidase adsorption has been undertaken from a solution of the enzyme (0.125 mmol dm⁻³) in acetate buffer (pH 4) onto mesoporous aluminosilicates synthesized in the presence of biomolecules (lecithin, ...

The method of synthesis of silica gels containing small additives of Al and Zr ions was developed. The porous structure of the synthesized Al,Zr-silica gels has been characterized by the adsorption method. It was found ...
