General description
Application
- Pickering emulsion polymerization using a silicon dioxide nanoparticle stabilizer to form molecularly imprinted polymers for steroid recognition.
- Mesoporous silica is used as a catalyst support in the preparation of multiwalled carbon nanotubes (MWCNTs).
- It is used as a ring opening of tetrahydrofuran-dimethanol to 1,2,6-hexanetriol.
- It maybe used to prepare silica/brominated poly(phenylene oxide) nanocomposites membranes for CO2 seperations.
- The composite scaffold of chitosan/chondroitin sulfate/nano-SiO2 was fabricated by lyophilization.
- Nanocomposites preparation of silica, single-wall carbon nanotubes, and graphite nanoplatelets in an epoxy matrix have been reported.6
- Dielectric spectroscopy study of the polystyrene/nanosilica model system has been studied.
- PMMA SiO2 nanocomposites were reported to be synthesized.

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.
Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.
Silica is a very popular inorganic nanomaterial used in a wide range of applications including fillers for rubber, catalyst supports, separation media, carriers in food and agriculture, and abrasive/anticaking agents in cosmetics. It is also widely believed to be an important material for biomedical applications for following reasons.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
