Organic-inorganic hybrid silica. Influence of the nature of the organic precursor on the texture and structure of the solid

Synthesis and characterisation of polymeric nanofibers poly (vinyl alcohol) and poly (vinyl alcohol)/silica using indigenous electrospinning set up

“…The network between PVA and silica suppresses the swelling of PVA in water and enhances its thermal stability 15 . The production of these organic/inorganic nanocomposites and its preparative constitution were reported for its duration and fiber quality [16][17][18][19][20][21] . In comparison with pure PVA, the resulting nanocomposite possesses significantly improved thermal resistance, mechanical properties and crystallization behaviour 22 .…”

Novel Optical Device Materials - Molecular-Level Hybridization

“…[1][2][3][4][5][6][7][8][9][10] Usually, hybrid materials mixed at the bulk scales retain the original properties of the individual organic and inorganic components. In other words, their final properties are significantly influenced by the characteristics and their domain sizes of individual components after the mixing process at the bulk scales.…”

“…To overcome those limitations of the bulk-scale mixing technique, molecular-level hybridization technique has been actively investigated. [1][2][3][4][5][6][7][8][9][10] This technique results in molecular-level composites, which are their domain sizes in the nanometer scale often create new properties, which would not be expected from those individuals by the loss of individuals' identities after the molecular-level mixing process thereby creating new properties.…”

“…[1][2][3][4][5][6][7][8][9][10] Furthermore, the molecularlevel mixing technique doesn't show any significant phase separation; because, the molecularlevel hybridization is based on a microscopically homogeneous mixing and thus the uniform distribution of organic and inorganic moieties in a domain size at the molecular level is provided.…”

Dynamic Catalysis in Aerobic Oxidation by Sol-Gel Living Materials

“…Sol±gel materials, for instance, grow by kinetic control, [18] and not by thermodynamic control, and often resulting in ªlivingº materials that undergo structural modifications, and thus changes in reactivity, even months after preparation. The hydrolysis and condensation reactions at the base of the sol± The catalytic activity of hybrid organic±inorganic silica glasses doped with the ruthenium species tetra-n-propylammonium perruthenate (TPAP) in the aerial oxidation of alcohols to carbonyl compounds, either in toluene or in dense-phase CO 2 , substantially increases with time several months after the xerogels' preparation, yielding the most active ruthenium-based aerobicoxidation catalysts reported thus far.…”
