for over 70 years. By the early 1940's, precipitated and fumed silica nanoparticles were being manufactured and sold in USA and Germany as substitutes for ultrafine carbon black for rubber reinforcements. Nanosized amorphous silica particles have found largescale applications in many everyday consumer products, ranging from

Chemical nature of aluminosilicatestozeolites conversion. The chemical nature of largescale aluminosilicates is simple. They are essentially a broad range of minerals constructed from [AlO 4] tetrahedra [AlO 6] octahedra, and [SiO 4] tetrahedra [24, 25].These polyhedra bind together via the shared oxygen with different topological structures, resulting in rich crystal structures.

Amorphous silica is a naturally occurring or synthetically produced oxide of silicon characterized by the absence of pronounced crystalline structure, and which has no sharp peaks in its Xray diffraction pattern (Van Niekerk et al., 2002).There are several types of amorphous silica including fumed silica, colloidal silica, diatomaceous earth and precipitated silica.
Ultrafine particles are mainly produced during burning and in gas phase reactions. Examples include carbon black, welding fumes, laser fumes, exhaust gases, metal fumes, polymer fumes, amorphous silica. Ultrafine particles can also be formed by precipitation ( titanium dioxide, iron oxides).

Abstract. Silica dispersions of size ranging from 2060 nm with solid content ranging from 12 wt.% were prepared by hydrolysis followed by condensation of TEOS in methanol. Aqueous dispersions were prepared by adding appropriate amounts of water to the dispersion and removing the methanol by vacuum distillation in a rotary evaporator.

The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion reevaluating the safety of silicon dioxide (E 551) when used as a food additive. The forms of synthetic amorphous silica (SAS) used as E 551 include fumed silica and hydrated silica (precipitated silica, silica gel and hydrous silica).
Silicosis is a lung disease and type of pneumoconiosis caused by inhaling an excessive amount of crystalline silica dust or the microscopic particles of volcanic dust. The dangers of inhaling an excessive amount of volcanic ash can't be emphasized enough. The particles of volcanic ash have been compared to microscopic shards of glass, and ...

1. Introduction. The demand for high strength construction materials is the force behind the development of UltraHigh Performance Concrete. Bouygues was the first to start research in Reactive Powder Concrete, a kind of UHPC from 1990 to 1995 [1].The prestressed hybrid pedestrian bridge at Sherbrooke in Canada completed in 1997 was the first engineering structure application of UHPC [1], [2].
Sub100 nm hollow carbon nanospheres with thin shells are highly desirable anode materials for energy storage applications. However, their synthesis remains a great challenge with conventional strategies. In this work, we demonstrate that hollow carbon nanospheres of unprecedentedly small sizes (down to ∼ nm and with thickness of ∼ nm) can be produced on a large scale by a ...
