The demand for agricultural crops continues to escalate with the rapid growth of the
population. However, extreme climates, pests and diseases, and environmental pollution …

Colloidal silica particles have received a widespread interest because of their potential
applications in adsorption, ceramics, catalysis, drug delivery and more. Among many …

Some characteristics of silica-based materials, such as the control/adjustment of their
physical and chemical properties, compatibility, and friendly-use synthesis methods, have …

In this work, we investigated the kinetic balance between ammonia-catalyzed hydrolysis of
tetraethyl orthosilicate (TEOS) and subsequent condensation over the growth of silica …

Silica nanoparticles (SNPs) are produced on an industrial scale and are an addition to a
growing number of commercial products. SNPs also have great potential for a variety of …

The rapid development of nanomaterials with unique size-tunable properties forms the basis
for a variety of new applications, including temperature sensing. Luminescent nanoparticles …

We demonstrate that the silica shell on nanoparticles formed by a typical Stöber method is
inhomogeneous in nature. The outer layer of the shell is chemically more robust than the …

In this paper, Stöber process with high concentration of tetra-ethyl-orthosilicate (TEOS) up to
1.24 M is used to prepare monodisperse and uniform-size silica particles. The reactions are …

This work delineates the effect of different reaction variables on the outcome of
heterogeneously catalyzed reactions, and explains how to optimize the product yield of …

We report on the synthesis and characterization of highly monodisperse amorphous silica
nanoparticles (ASNs) and mesoporous silica nanoparticles (MSNs) with particle sizes of 15 …
