in this study, alkaline colloidal silica was prepared by titration of an alkaline solution such as sodium silicate with silicic acid in constant range of ph .this constant range of ph was achieved by using concentrated soduim silicate solutions as ph adjusting solutions during titration.the sodium silicate solutions having a variety of concentrations were passed through ion-exchange resin to...
The present study describes for the first time the synthesis of silica nanoparticles starting from sodium silicate and oleic acid (OLA). The interactions between OLA and sodium silicate require an optimal OLA/OLANa molar ratio able to generate vesicles that can stabilize silica particles obtained by the sol-gel process of sodium silicate. The optimal molar ratio of OLA/OLANa can be ensured by a...
A number of oral preparations of various forms of silicon were fed to young adult Beagle dogs and young rats of both sexes for a period of four weeks. During the test period the animals were observed for clinical symptoms and urine and blood measurements were made. At the end of the experimental period all animals were sacrificed and subjected to a complete necropsy and histopathologic study. P...
This study was conducted to investigate the effects of different silicon supplements and postharvest treatments on growth and yield of gerbera in a greenhouse experiment. Silicon supplements were including potassium silicate at three concentrations (0, 140 and 200 mg L−1), sodium silicate at three concentrations (0, 50 and 100 mg L−1) and rice hull ash (RHA) at three concentrations (0, 50 and 1...
A Comparative Study of Insulators on Magnetic Properties of Sendust Based Nanocomposite Powder Cores
In this study, Sendust (Fe85Si9.6Al5.4) nanostructure alloy was prepared bymechanical alloying and was characterized by X-ray diffraction. In addition, the alloy’smorphology and its distribution particle size were investigated by scanning electronmicroscopy method. The alloyed powders were insulated with 4wt% of three differentinsulating materials including polyvinyl alc...
Dendranthema grandiflorum L. is one of the widely cultivated flowers around the world for producing of cut flowers. Nanometer-sized silver particles are used in various applications as an anti-microbial compound. This experiment was carried out to study the effects of silver nanoparticles (0, 5, 10 and 20 mg/L) and sodium silicate (0, 50, 100 and 150 mg/L) on longevity and quality of cut chrysa...
Purpose: It has been shown that sodium meta silicate has an antioxidant effects and suppress the production of oxidative enzymes. Since the inflammation phenomena and increase the level of free radicals mostly take part in post-injury neuronal degeneration, the purpose of the present research was to examine weather the antioxidant property of sodium meta silicate can prevent the central degener...
The present work is focused on the preparation of biocompatible silica particles from sodium silicate, stabilized by a vesicular system containing oleic acid (OLA) and its alkaline salt (OLANa). Silica nanoparticles were generated by the partial neutralization of oleic acid (OLA), with the sodium cation present in the aqueous solutions of sodium silicate. At the molar ratio OLA/Na⁺ = 2:1, the m...
