Nanosilica is one of the most widely used nanomaterials across the world. However, their assessment data on the occupational exposure to nanoparticles is insufficient. The present study performed an exposure monitoring in workplace environments where synthetic powders are prepared using fumed nanosilica. Furthermore, after it was observed during exposure monitoring that nanoparticles were emitt...

Wild animals, pets, zoo animals and mammals of veterinary importance heavily suffer from trypanosomiasis 1 . Drugs with serious side effects are currently mainstay of therapies used by veterinarians. Trypanosomiasis is caused by Trypanosoma sp. leading to sleeping sickness in humans. Surface modified (hydrophobic and lipophilic) amorphous nanoporous silica molecules could be effectively used as...

There have been no reports of the simultaneous application natural fillers, such as magnetite and zeolites, to increase strength composites containing silica (SiO2) fillers reinforcing in rubber. This study has investigated effect magnetically modified zeolite on nanosilica-reinforced rubber that include a mechanical characteristic like human tissue. We use technical specifications (TSR) SIR 20...

With polymer nanocomposites, achieving highly effective dispersion of agglomerated nanofiller and major or optimal property enhancements remain challenges. A commonly posited solution is to improve the polymer-filler surface thermodynamic compatibility; this approach has led to significant improvements in some cases, but it has not provided a general solution. We address the question of whether...

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...

Morphology-controlled nanomaterials such as silica play a crucial role in the development of technologies for addressing challenges in the fields of energy, environment, and health. After the discovery of Stöber silica, followed by that of mesoporous silica materials, such as MCM-41 and SBA-15, a significant surge in the design and synthesis of nanosilica with various sizes, shapes, morphologie...

Fly Ash Belite cement (FABC) pastes with and without nanosilica additions have been prepared and maintained in sulfate solutions (Na2SO4 0.5 M) for 180 days. The mechanical performance and the changes in microstructure have been monitored at 28, 90 and 180 days by compressive strength, X-ray diffraction (XRD) and Si MAS NMR measurements. We have found that, unexpectedly, and contrary to what ha...

Various types of surface functionalized nanosilica (50-60 nm size with 3-10 nm inner pore size range) have been used to kill insect pests by sucking up cuticular lipids and breaking the water barrier 1,2 . We have also utilized nanosilica for mopping up host lipids induced by the malarial parasite, P. gallinaceum in poultry birds; VLDL cholesterol and serum triglycerides are brought back to the...
