Composites with nanosilica

2015 IEEE 11th International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2015
There are only a few materials that are promising composites. For decades high-voltage electrical insulation technology used ternary insulation systems; usually based on modified epoxy resins and reconstructed mica. Adding additional components into existing systems, it is possible to influence their properties.

Aqueous Nanosilica Dispersants for Carbon Nanotube

Langmuir, 2015
Nanosilicas can disperse single-wall carbon nanotube (SWCNT) in aqueous solution efficiently; SWCNTs are stably dispersed in aqueous media for more than 6 months. The SWCNT dispersing solution with nanosilica can produce highly conductive transparent films which satisfy the requirements for application to touch panels.

Nanosilica-based Conformance Gels

SPE European Formation Damage Conference and Exhibition, 2015
Abstract Conformance gels based on nanosilicas are used as environmentally acceptable materials for plugging and sealing water- or gas-producing zones and controlling water production. Because of the lower pH(compared to sodium silicate solutions) of these solutions, they are environmentally acceptable in the North Sea area.

Nanosilica? Clarifications are necessary!

Nanotoxicology, 2011
Sir: With interest we read the publication by Dekkers et al. (2010) on the presence and risks of nanosilica in food products. We agree on the major conclusions presented by the authors.

Nanosilica-toughened polymer adhesives

Materials & Design, 2014
Abstract High-performance adhesives are of great importance to achieving strong and durable adhesive bonds in a wide range of applications. This article presents an investigation of the use of nano-sized silica particles to improve the fracture toughness of polymer adhesives, focusing on the effects of particle size, matrix ductility and adhesive ...

Nanosilica—from medicine to pest control

Parasitology Research, 2008
Nanotechnology is a broad interdisciplinary area of research, development, and industrial activity that has been growing rapidly worldwide for the past decade. More ambitious uses of nanoparticles are bioremediation of contaminated environments, controlled release of fragrances, biocides, and antifungals on textiles. Silica nanocomposites have received

Effect Of Olivine Nanosilica On The Reinforcement Of Natural Rubber Nanosilica Composites

Materials Today: Proceedings, 2019
Abstract In this work an alternative route to produce nanosilica using a low cost raw material –olivine is suggested. Nanosilica is produced by the dissolution of olivine in acid. The olivine dissolution is a low temperature process making this process cheaper and greener.

Photocurable, Antimicrobial Quaternary Ammonium–modified Nanosilica

Journal of Dental Research, 2015
In this study, novel, quaternary ammonium methacrylate–modified silica nanoparticles (QMSNs) were synthesized for the first time and proposed as possible antimicrobial particles for free-radical, photocurable monomers. Such monomers have the potential to polymerize with other methacrylate monomers and create antimicrobial polymers.

Dispersion and Surface Characteristics of Nanosilica Suspensions

Annals of the New York Academy of Sciences, 2009
Nanofluids consisting of nanometer‐sized particles dispersed in base liquids are known to be effective in extending the saturated boiling regime and critical heat flux in pool boiling. The heat transfer characteristics of nanosilica suspensions with particle sizes of 10 and 20 nm in pool boiling with a suspended heating Nichrome wire have been analyzed.

Nanosilica synthesis mediated by Aspergillus parasiticus strain

Fungal Biology, 2018
Rice husks (RHs) are plant waste materials abundant in phytoliths silica bodies. These were used as starting material for fungal-mediated biotransformation leading to the synthesis of a high-value added product. A strain of Aspergillus parasiticus was capable of transforming the amorphous silica conglomerates into structured nanoparticles (NPs) in the ...
