In this work, ZnO nanoparticles (NPs) were successfully synthesized and coated with oleic acid (OA). The mean diameter of these NPs (ZnO-OA) was around 11.5 nm, their core characterized by XRD coating FTIR Raman. Homogeneous dispersions at different concentrations (0.10, 0.25, 0.50, 0.75 1.00 wt%) ZnO-OA in polyalphaolefin 40 (PAO40) oil thermophysically tribologically characterized. Both densi...

The energy production processes from fossil fuels represent the first anthropogenic source of mercury emissions in Europe and the second in the world. Among the different possibilities that can be posed to reduce these emissions, this work focuses on the use of regenerable sorbents based on gold nanoparticles dispersed on activated carbon foam. The use of regenerable sorbents would not only all...

Objective: The aim of this study to manufacture the prolonged release lipid nanoparticle (Solid and nanostructure carrier) repaglinide for enhance oral bioavailability. Methods: Solid nanoparticles (SLN) Nanostructured carriers (NLC) were prepared by slight modification in solvent diffusion method. core material used as cetyl alcohol while blend with oleic acid was preparation NLC dispersion. T...

In this work, antifriction and antiwear capabilities of hexagonal boron nitride nanoparticles (h-BN) or graphene nanoplatelets (GnP) as additives a polyalphaolefin neat oil (PAO 40) were studied at pure sliding conditions. For purpose, eight PAO 40 nanodispersions prepared: four with h-BN others based on GnP. The mass concentrations these dispersions are 0.25, 0.50, 0.75 1.00 wt% 0.05, 0.10. 0....
