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

Probabilistic modeling of the flows and environmental risks of nano-silica
Science of The Total Environment, 2016Nano-silica, the engineered nanomaterial with one of the largest production volumes, has a wide range of applications in consumer products and industry. This study aimed to quantify the exposure of nano-silica to the environment and to assess its risk to surface waters.

Amorphous non-nano silica spheres
2022Disclosed herein are methods of deriving silica from biological materials, compositions of such matter, articles of manufacture and amorphous silica spheres. Evidence demonstrates what is disclosed herein to be superior to the silica obtained from sand and other non-renewable sources of silica in personal care products, particularly cosmetics.

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

Nano-Macro Correlation of Nano-Silica Concrete
Concrete mixes using progressively finer size nano-silica particles (7–150nm) were prepared to study the effect of nano-size pozzolans (nano-silica). Conventional compression tests demonstrated progressively higher strength with finer size of the nano-silica down to 12nm particle size.Joan Schoepfer, Arup Maji
