Abstract Hybrid composites were prepared from a PP homopolymer, talc and PVA fibers by twin-screw extrusion injection molding. Talc was added to improve stiffness, while the serve increase impact resistance. Mechanical properties characterized tensile testing, structure studied SEM optical microscopy. The results showed that has strong nucleating effect in used spite of fact grade contained age...

Colloidal particles interacting via a long-range repulsion can, in contrast to hard-sphere systems, exhibit crystalline ordering at low volume fraction. Here we experimentally investigate the structure and properties of such "colloidal Wigner crystals." We find a body-centered-cubic crystalline phase at volume fractions of ϕ≳15%, which exhibits large fluctuations of individual particles from th...

ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...
