Facile methods were developed to prepare hybrid poly(ionic liquid)-bonded silica for a wide range of applications, particularly in analytical chemistry. The hybrid material obtained was evaluated by comparing its adsorption capacity with other conventional separation materials. In addition, the hybrid material has the potential for industrial scale production.

Inclusion complexes of cyclodextrins with organometallic coordination compounds of Pd, Pt, Rh, Fe, Ni, and Ru have been used to produce porous metal-silica hybrid materials. The cyclodextrins are templates for the structure of the silica and lead to a uniform “wormtype” pore system. After the templating step the organometallic compounds can be employed as in situ precursors for the preparation ...

Silica aerogels functionalized with strongly fluorescent carbon quantum dots were first prepared and used for simple, sensitive, and selective sensing of NO2 gas. In the presence of ethanol, homemade silica aerogels with a large specific surface area of 801.17 m(2)/g were functionalized with branched polyethylenimine-capped quantum dots (BPEI-CQDs) with fluorescence quantum yield higher than 40...

The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...

Gallic acid has been covalently conjugated to SBA-15 mesoporous silica surface through different linkers. Cytotoxic activity of the hybrid organic-inorganic systems against HeLa and KB cell lines has been analyzed. Up to 67% of HeLa or KB tumor cells growth inhibition has been achieved at low silica concentration used (10 μg mL(-1)).

This work reports on the nanoscale assembly of hybrid lanthanum oxide and silica structures, which form patterns of interfacial dense and porous networks. It was found that increasing the molar ratio of lanthanum nitrate to tetraethyl orthosilicate (TEOS) in an acid catalysed sol-gel process alters the expected microporous metal oxide silica structure to a predominantly mesoporous structure abo...

The association of natural polymers with silica is a fruitful strategy to design novel hybrid structures with potential applications in the fields of biotechnology, medicine, and environmental sciences. Here we illustrate the principles of formation, the structure, and the properties of such biohybrid systems by the specific example of silica–pectin porous materials. The influence of the silica...

A facile "one-pot" approach to prepare organo-silica hybrid capillary monolithic column with intact mesoporous silica nanoparticle (IMSN) as crosslinker and building block was described. An IMSN crosslinked octadecyl-silica hybrid capillary monolithic column (IMSN-C18 monolithic column) was successfully prepared, and the effects of fabrication conditions (e.g. concentration of intact mesoporous...

Hybrid nanofibrous membranes of poly(lactic-co-glycolic acid) (PLGA) and chitosan with different chitosan amounts (32.3, 62.7, and 86.5%) were fabricated via a specially designed electrospinning setup consisting of two sets of separate syringe pumps and power supplies. After soaking in chloroform overnight to dissolve PLGA, the amount of chitosan in the hybrid membranes was determined. The stru...
