Nature, 1950
THE luminescence associated with the wetting of finely divided solids has already been reported1–3. With greatly improved arrangements for heating the solid, redistilling the wetting liquid and wetting the solid in the same vacuum, it has now been found that silica from various sources heated in vacuo to 700° C.

Mechanism of silica deposition in sorghum silica cells
New Phytologist, 2016Summary Grasses take up silicic acid from soil and deposit it in their leaves as solid silica. This mineral, comprising 1–10% of the grass dry weight, improves plants' tolerance to various stresses. The mechanisms promoting stress tolerance are mostly unknown, and even the mineralization process is poorly understood.

Zone electrophoresis in silica gel and silica paste
Biochimica et Biophysica Acta, 1960Abstract Silica gel and silica paste have been used as anticonvection media in zone electrophoresis. Rapid methods for preparing gels and pastes containing the appropriate electrophoretic buffer, and their use in zone electrophoresis, are given.

Silica-Sepiolite Nanoarchitectures
Journal of Nanoscience and Nanotechnology, 2013Silica-sepiolite heterostructured materials have been prepared as novel nanoarchitectures by generation of SiO2 nanoparticles (NPs) on the surface of the sepiolite fibrous clay mineral. The synthetic approach implies the use of organo-sepiolites dispersed in isopropanol to which is incorporated a selected silicon alcoxysilane, such as ...

Toxicity of Silica Nanomaterials: Zeolites, Mesoporous Silica, and Amorphous Silica Nanoparticles
2010Publisher Summary In this chapter, an overview of the toxicity of silica-based nanomaterials is presented. Porous materials, such as crystalline, microporous zeolites, and mesoporous silica materials, have two nanoscale aspects: nanoscale pores that provide large internal surface areas and nanoscale crystal or particle sizes that may lead to unique ...
