Application of silicate solutions to living or heat-killed pneumococci and to certain "viridans" streptococci causes their conversion from a Gram-positive to a Gram-negative state. The original staining properties can be restored by suspending the silicate-treated bacteria in alkaline solutions of various salts but not by simple washing in water. Living pneumococci and the strains of streptococ...

We present a photometric selection method for ULIRGs in the redshift range of z = 1 – 2. We utilize the most prominent spectral feature of ULIRGs, i.e. the silicate absorption feature at 9.7 μm and an optimized filter system at mid-infrared wavelengths. These ‘silicate-break’ galaxies could be selected by using colour anomalies owing to the silicate absorption feature around 9.7(1+z) μm. Such f...

The local structure of apatite-type lanthanum silicates of general formula La9.33+x(SiO4)6O2+3x/2 has been investigated by combining the atomic pair distribution function (PDF) method, conventional X-ray and neutron powder diffraction (NPD) data and density functional theory (DFT) calculations. DFT was used to build structure models with stable positions of excess oxide ions within the conducti...

in order to determine the effect of potassium silicate solution with elements of macro and micro elements on agronomic traits of rice, tarom, a field experiment in paddy fields galogah city - village marbles of the crop year 2014 was conducted. the results showed that the highest plant height (013/180 cm) to 2 liters per hectare and no interaction effects of potassium silicate elements. the res...

The mechanical and biological properties of silicate-crosslinked PEO nanocomposites are studied. A strong correlation is observed between silicate concentration and mechanical properties. In vitro cell culture studies reveal that an increase in silicate concentration enhances the attachment and proliferation of human mesenchymal stem cells significantly. An upregulation in the expression of ost...

Mixed borohydride-chloride complexes of lanthanum and neodymium having the 2,5bis{N-(2,6-diisopropylphenyl)iminomethyl}pyrrolyl ligand in the coordination sphere were synthesised by the reaction of potassium 2,5-bis{N-(2,6-diisopropylphenyl)iminomethyl}pyrrolyl [(DIP2-pyr)K] with a 1:1 mixture of [Ln(BH4)3(THF)3] and LnCl3 (Ln = La, Nd). Both compounds are dimeric in the solid state. The metal ...

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...
