Silica nanoparticles were synthesized by chemical methods from tetraethylorthosilicate
(TEOS), polyethylene glycol 5% and hydrochloric acid 0.001 N. The sol-gel process was …

Compared to the synthesis of silica nanoparticles from tetraethyl orthosilicate, its synthesis
from sodium silicate solution (SSS) in alkaline medium is less investigated. Herein, we …

Sol-gel method is the simplest method and has the ability to control the particle size and
morphology through systematic monitoring of reaction parameters. The objective of this …

Silica nano-particles were synthesised by chemical methods from tetraethylorthosilicate
(TEOS), ethanol (C 2 H 5 OH) and deionized water in the presence of ammonia as catalyst …

A modified preparation of silica nanoparticles via sol–gel process was described. The ability
to control the particle size and distribution was found highly dependent on mixing modes of …
