Fabrication of Nano Silica Dispersed Permalloy Composite Coating
Journal of Nanoscience and Nanotechnology, 2012In aqueous solution, the agglomeration of silica nanopowder is a major problem which causes poor uniformity of electroplated surfaces. Silica surface is susceptible to moisture due to the hydroxyl group on its surface which causes the silica nanopowder to become agglomerated.

Effect of Micro/Nano Silica Particle Feeding for Mice
Journal of Nanoscience and Nanotechnology, 2008The toxic effect of nano and micron sized silica particle was studied on mice. The size of the nano and micron sized silica were approximately 30 nm and approximately 30 microm, respectively. The mice, Balb/c (20 approximately 30 g, white) and C57BL/6J (black) for the experiment were classified to normal, nano sized silica (1%), and micron sized silica

Application of nano-silica in concrete
2012This report presents the achievements of the 2012 third quarter focusing on the application of nS in concrete. In this context, nano-silica precipitated from the olivine dissolution in acid (OnS) and nano-silica sludge (nSS) were used for the experimental work.

Preparation of Nano-silica and Nano-silicone
Scientific Journal of King Faisal University: Basic and Applied SciencesIn this research, silica and silicon were prepared using glass waste. The preparation process consisted of several stages that started with the collection of crushed glass samples, treating them physically (grinding and granular sorting) and mixing granulated crushed glass with NaOH at ratios of 1:1, 1:2 and 1:3.

The Investigation of Nano Silica in the Cement Hydration Process
SP-267: Nanotechnology of Concrete: The Next Big Thing is Small, 2009With the advent of nano technology, materials have been developed that can be applied to high performance concrete mix designs. Nano silica reacts with calcium hydroxide (CH) to develop more of the strength carrying structure of cement: calcium silica hydrate (CSH). In this paper, relationships have been developed to distinguish the benefits when using
