From its initial use to describe hydrolysis and condensation processes, the term 'sol–gel'is
now used for a diverse range of chemistries. In fact, it is perhaps better defined more broadly …

Versatile bio-derived catalysts have been under dynamic investigation as potential
substitutes to conventional chemical catalysts for sustainable biodiesel production. This is …

Rice husk is a form of agricultural biomass that provides an abundant silicon source. This
study used rice husk as a raw material to prepare nanosilica without adding an extra …

Agricultural wastes management is one of the biggest burdens in the 21st century. To
reduce pollution from agricultural waste, different types of research have been conducted to …

Mesoporous silica nanoparticles with a spherical morphology have been synthesized from
rice husk (agricultural biomass) by a simple, template-free synthetic approach, which was …

Silica is the most abundant components in the earth's crust and is made by way of synthesis
for use in the application of technology. Silica are generally found commercially as …

An environmentally friendly and economically effective process to produce silica and
activated carbon form rice husk ask simultaneously has been developed in this study. An …

We report a method to synthesize silica nanoparticles from bentonite clay. A series of
thermal and acid treatment processes was performed on bentonite clay to lower the alumina …

A recyclable technology was proposed for preparation of silica powder using rice hull ash
and NH4F. The silica in rice hull ash was dissolved into NH4F solution to produce (NH4) …

The electronics industry is heavily reliant on the use of silicon in devices ranging from solar
panels to circuitry. This is of growing concern due to the environmental impact of sourcing …
