In order to evaluate the effect of potassium silicate spray on the control of coffee leaf rust and coffee yield, an experiment was conducted during the 2005/2006 and 2006/2007 growing seasons on Coffea arabica cv. Catuaí Vermelho IAC 144, in a location situated at an elevation of 850 m in Coimbra, Minas Gerais, Brazil. The treatments consisted of: 1 potassium silicate; 2 potassium silicate + co...

Background Recently a new generation of endodontic sealers has been developed based on calcium silicate as MTA Fillapex, Endoseal MTA, Total Fill BC Sealer, EndoSequence BC Sealer, iRoot SP, Endo CPM sealer, MTA-Angelus and ProRoot Endo Sealer. A review of literature was conducted to discuss the composition, physicochemical properties, and clinical perspectives of calcium silicate based sealers...

Density functional theory is used to determine the possible crystal structure of the CaSiO3 perovskites and their evolution under pressure. The ideal cubic perovskite is considered as a starting point for studying several possible lower-symmetry distorted structures. The theoretical lattice parameters and the atomic coordinates for all the structures are determined, and the results are discusse...

While soluble silicate binders have been used effectively for decades in various end uses, recent developments and discoveries may improve and expand the use of silicates. This paper reviews the traditional use and chemistry of sodium silicate binders and also describes how surfactants, viscosity modifiers, lubricants and non-traditional setting agents can provide new characteristics and flexib...

The function(s) of soluble silicates in repulpinghashing and flotation deinking of waste newsprint/magazine were investigated extensively, under optimized conditions. During repulping/washing, silicate ’s response was characteristic of a buffer and a detergent. It was responsible for a 3.0% increase in I S 0 brightness. In repulping/flotation, silicate accounted for a 6.1% increase in I S 0 bri...

Novel silicate nanoplatelets that induce osteogenic differentiation of human mesenchymal stem cells (hMSCs) in the absence of any osteoinductive factor are reported. The presence of the silicate triggers a set of events that follows the temporal pattern of osteogenic differentiation. These findings underscore the potential applications of these silicate nanoplatelets in designing bioactive scaf...
