TL;DR: In this article, a class of carbon/silica composite with a porous bicontinuous nanostructure is prepared via a simple sol-gel method and then used as anode material for lithium-ion batteries.

TL;DR: In this paper, the effects of synthesis pH, alcohol/alkoxide ratio, and buffer type were examined using UV-V is absorption spectroscopy for cytochrome c -doped materials and gasometric analysis for assays of catalase in gels.
Abstract: The encapsulation of biological molecules in sol-gel materials has led to the development of a new class of chemical and biomedical sensors. The influence of sol-gel synthesis conditions on the stability, chemical function, and enzymatic reactivity for horse heart cytochrome c and bovine liver catalase encapsulated in silica sol-gel materials was studied. The effects of synthesis pH, alcohol/alkoxide ratio, and buffer type were examined using UV-V is absorption spectroscopy for cytochrome c -doped materials and gasometric analysis for assays of catalase in gels. In general, the behavior of the proteins encapsulated in silica gels mirrored their behavior in solution suggesting that the stability limiting factor for encapsulating these biological molecules is determined by the solution stability of the protein. In the case of catalase, the results indicate that the silica gel stabilizes the encapsulated enzyme to higher methanol concentrations.

TL;DR: The 3,5-dimethylphenylcarbamates of cellulose and amylose bearing a small amount of 3-(triethoxysilyl)propyl residues were synthesized by a simple process and efficiently immobilized onto a silica gel support by intermolecular polycondensation of the triethoxisilyl groups.
