Silica consists of one silicon atom and two oxygen atoms (SiO2) and is commonly used in various aspects of daily life. For example, it has been used as glass, insulator, and so on. Nowadays, silica is used as core reagents for fabricating and encapsulating nanoparticles (NPs).

Determination of crystalline silica in silica fume
Talanta, 1994Silica fume is formed as a by-product in the manufacture of silicon from quartzite. This paper describes an analytical method for the determination of crystalline silica in silica fume. The crystalline silica was determined after removal of amorphous silica from the fume. A gravimetric method was developed for the determination of the total crystalline

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2004
We review how molecular dynamics computer simulations are providing a comprehensive picture of the behaviour of silica, as modelled by the van Beest–Kramer–van Santen (BKS) potential. We have recently evaluated a number of key properties of this model system: the phase diagram, including melting lines of three crystal phases; the equation of state and ...

We report here the results of nanoparticle-catalyzed synthesis of a variety of silica nanocoils (SiNCs) under similar growth conditions to those of making regular straight silica/silicon nanowires (SiNWs). Synthesis of individual SiNCs with alternating coiled and straight segments was achieved with cobalt nanoparticle catalysts at alternating ...

Adsorption study of alkyl-silicas and methylsiloxy-silicas
Journal of Chromatography A, 2001We report the synthesis and adsorption study of the lyophobic porous silicas. Four adsorbents were prepared and tested: (1) octyl-silica, (2) hexadecyl-silica, (3) bis(trimethylsiloxy)-silica, and (4) oligo(dimethylsiloxane)-silica. Octyl- and hexadecyl-silicas were prepared via the reaction of silica with (CH3)2NSi(CH3)2CnH(2n+1) (n=8 and 16), the ...

Properties of silica and silica-titania layers fabricated from silica sols containing fumed silica
Optical Materials, 2018Abstract Silica layers fabricated by the sol-gel method are usually amorphous and exhibit a relatively low refractive index (n∼1.46 at about 0.6 μm), high optical transmittances at UV-VIS and near-IR ranges, as well as high thermal stability. Such layers can be used as high reflection or antireflection coatings, dielectric mirrors, bandpass filters ...

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.

Silica in Sea Water: Control by Silica Minerals
Science, 1967Silicate minerals typical of those carried in the suspended load of streams release silica to silica-deficient sea water and abstract silica from silica-enriched sea water. Experimental rates of release and uptake permit the conclusion that the suspended solids carried into the oceans by streams are a major control of the concentration of silica in the

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.
