Obtaining transparent silica glass from nano-silica hydrosol
Ceramics International, 2021Abstract Transparent silica glass is widely used in various fields. However, a simple and economical method of synthesis remains to be developed for high-precision device manufacturing. In this study, transparent silica glass is fabricated from low-cost commercial nano-silica hydrosol.

The reactivity of nano silica with calcium hydroxide
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2011AbstractThe reactivity of nano silica (SiO2) with calcium hydroxide (Ca(OH)2) was evaluated and characterized in this study. Ca(OH)2 activated nano SiO2 takes place through an exothermic process, which is mainly attributed to the breakdown of SiOSi bonds.

Nano-sensing with a Silica Microtoroid
CLEO:2011 - Laser Applications to Photonic Applications, 2011We report nano-detection using a silica microtoroid with a reference interferometer. Single polystyrene nano-beads at a record 12.5nm radius are detected; Influenza-A virion binding events with signal-to-noise ratio exceeding 38:1 are observed.

Nano-Silica Composite Laminate
2013 IEEE 63rd Electronic Components and Technology Conference, 2013This paper introduces a newly-developed Nano-Silica Composite Laminate packaging technology that utilizes a nano-silica matrix composite material with outstanding properties. Nano-Silica Composite Laminate packaging technology enables us to create a thinner, downsized packaging that is less susceptible to warpage.

Nano Silica in Cement Hydration
Materials Today: Proceedings, 2018Abstract In this paper, the performance of nanoscale SiO2 in cement paste has been studied. The compressive strength of hardened cement paste and the formation of Calcium Silicate Hydrate (C-S-H) in presence of nano silica (SiO2) increased. Heat of hydration increased with time with the addition of nanosilica.

Effect of colloidal nano-silica on alkali–silica mitigation
Journal of Sustainable Cement-Based Materials, 2016Alkali–aggregate reaction was first observed in the US during 1920s. In the last decades, several studies investigated the mechanisms of alkali–silica reaction in concrete and the extent of damage it may cause to the cementitious matrix. Research on alkali–silica reaction mitigation covers mainly the use of supplementary cementitious materials and ...

Coincorporation of nano‐silica and nano‐calcium carbonate in polypropylene
Journal of Applied Polymer Science, 2011AbstractIn this study, various polypropylene (PP) nanocomposites were prepared by melt blending method. The effects of different spherical nanofillers, such as 50 nm CaCO3 and 20 nm SiO2, on the linear viscoelastic property, crystallization behavior, morphology and mechanical property of the resulting PP nanocomposites were examined.

Materials Chemistry and Physics, 2019
Abstract In this research, micro-nano silica-silica nano-composite thin film was deposited on glass substrate by a sol-gel method. Then, the surface modification was performed by use of PFTS solution. The thin films were characterized by FTIR, EDS, FESEM, UV-Vis spectroscopy and water angle analyzer methods. Durability test was performed to check the

EFFECT OF NANO SILICA ON PROPERTIES OF CONCRETE
Full Text Book of Minar Congress 6, 2022This study presents experimentally the collective consequence of using nano silica (NS) on mechanical properties of tough concrete. NS is cast-off as partial cement substitution by 1,1.5,2 wt% . Mechanical properties of hardened concrete are assessed expending different mixtures between NS. Important enhancement in the mechanical properties of concrete
