In this work, the effect of immobilization of bread yeast (Saccharomyces cerevisiae) by sol-gel technique combined with functionalized nanoporous silica was investigated in different weight ratios of silica containing materials (TMOS: LUS-1). The activities of immobilized yeast in days after immobilization were examined. The results showed immobilization maintain the yeast life for a longer tim...

Metal oxide and metal dichalcogenide heterostructure composites are promising candidates for electrochemical use. In this study, a hybrid composite electrode material was made using straightforward hydrothermal process transition (NiO) (MoS2). The surface of the flower-like structured MoS2 grown with granular NiO, exhibited considerably improved specific capacitance when compared to pure NiO ma...

In this work, metal–organic frameworks (MOFs) were used as precursors to prepare Zn/Co oxide with a porous dodecahedral core-shell structure. Herein, low-temperature self-assembly calcination and hydrothermal strategy of imidazole-based Zn-Co-MOF was used. As anode lithium-ion batteries (LIBs), ZnO/Co3O4 has good cycling stability, the specific discharge capacity is stable at about 640 mAh g?1 ...

Rubbery ormosil films with immobilized aminofluorescein (AF) were investigated to develop an optochemical sensor for the determination of ammonia in water. The gel precursors with tetramethoxysilane (TMOS) and dimethyldimethoxysilane (DiMeDMOS) were deposited on glass supports, and characterized in terms of response to pH, and to dissolved ammonia at constant pH. After preconditioning the sensi...

Homogeneous poly(vinyl alcohol) (PVA)–silica gel polymer hybrids were prepared by in-situ hydrolysis of poly(vinyl acetate) (PVAc) in a sol– gel reaction mixture with tetramethoxysilane (TMOS). The degree of hydrolysis was evaluated by FTIR and C CP/MAS NMR; it increased with an increase in the acid catalyst and reached 85% with 1.6 ml of 0.1 M HCl. The homogeneity of the polymer hybrids obtain...
