Present study demonstrated the preparation of MCM-41 as a support for the immobilization of Candida rugosa lipase by the physical adsorption technique. The lipase immobilized MCM-41 has been characterized by scanning electron microscopic and FTIR techniques. At pH 6, maximum lipase immobilization (250 mg/g) on MCM support has been observed and the immobilized lipase was employed as biocatalyst ...

Highly ordered mesoporous MCM-41silica with hexagonal structure was synthesized using extracted amorphous silica from sedge (Carex riparia) ash. Obtained mesoporous materials functionalized by 3-(Aminopropyl) trimethoxysilane (APTMS) and their structures characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis (TGA) and Fourier transform infr...

The production of conjugated C4–C5 dienes from biomass can enable the sustainable synthesis many important polymers and liquid fuels. Here, we report first example bimetallic (Nb, Al)-atomically doped mesoporous silica, denoted as AlNb-MCM-41, which affords quantitative conversion 2-methyltetrahydrofuran (2-MTHF) to pentadienes with a high selectivity 91 %. incorporation AlIII NbV sites into fr...

The observation of molecular clusters has been of interest for some time. Molecular clusters can show quite different dynamic and static phase behaviour from bulk systems, and, because of their limited size, are accessible to computational molecular dynamics techniques.1-3 Experimentally, molecular clusters are made using several methods, including supersonic jets, vapours, confinement of phase...
