Long-term sustainability and decreasing amount of fossil oil reserves require a partial or complete transformation traditional lubricating oils. The use silica nanoparticles as lubricant additive has huge tribological potential, which already been discussed in numerous articles. Nanosized shows excellent results reducing friction preventing wear, but they quickly aggregate settle after homogeni...

This study encompasses the development and comparison of nanosilica-supported liposome (protocells), conventional liposome, and polyethylene glycol (PEG)-liposome. An effort was made to study the drug encapsulation efficiency and the in vitro release of the drug, and whether protocells (nanovesicles) could sustain the release of the drug by increasing the residence time, which could reduce the ...

The technological and economic benefits of engineered nanomaterials may be offset by their adverse effects on living organisms. One of the highly produced nanomaterials under such scrutiny is amorphous silica nanoparticles, which are known to have an appreciable, although reversible, inflammatory potential. This is due to their selective toxicity toward macrophages, and it is thus important to ...

Malaria and other parasites, including virus often induce an increase in host lipids which the invaders use to their own advantage. We obtained encouraging results in our investigations on bird malaria with a new approach namely the use of nanosilica to mop up excess host lipids 1, 2 . While this project is continuing we have investigated another, simpler system namely silkworms which suffer fr...

This study investigates the effect of a new pore filling material, named sodium silicate-based nanosilica (SS), on resisting the diffusion of the chloride ions. The proposed SS is chosen, mainly due to its smaller particle size, compared to the conventional ethyl silicate-based nanosilica. Each particle of SS is chemically treated to have the negative (-) charge on its surface. Four types of mi...

The recycling of waste glass is a major problem for municipalities worldwide. The problem concerns especially colored waste glass which, due to its low recycling rate as result of high level of impurity, has mostly been dumped into landfills. In recent years, a new use was found for it: instead of creating waste, it can be recycled as an additive in building materials. The aim of the study was ...

With advances in the development of various disciplines, there is a need to decipher bio-behavioural mechanisms via interdisciplinary means. Here, we present an interdisciplinary study of the role of silica nanoparticles (SiO2-NPs) in disturbing the neural behaviours of zebrafish and a possible physiological mechanism for this phenomenon. We used adult zebrafish as an animal model to evaluate t...

The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...

This study compares different polymer-nanofiller blends concerning their suitability for application as insulating thermoplastic composites High Voltage Direct Current (HVDC) cable application. Two polymer blends, PP/EOC (polypropylene/ethylene-octene copolymer) and PP/PP-HI (polypropylene/ propylene - ethylene nanocomposites filled with 2 wt.% of fumed silica modified 3-aminopropyltriethoxysil...
