The amount of concrete utilized worldwide has lately grown due to rising populations and urbanization. gas emissions during cement manufacturing the usage common resources result in a significant environmental threat. As result, researchers are attempting minimize consumed by using waste materials while lowering building costs. This research aims used partially replacing it with ceramic powder ...

Polyurethane is one of the polymers used in recent years for production thermal insulators. The aim present study was to optimize heat transfer polyurethane foam using clay nanoparticles and microparticles from polypropylene waste central composite design response surface methodology with help Design-Expert V.11 software. For this purpose, effect three independent variables thickness (0.5–1.5 c...

higher solid contents (20 % and 40 %) nanocomposites of poly (styrene-co-butyl acrylate) including higher content of cloisite 30b (7 wt% and 10 wt %) were prepared via miniemulsion polymerization. stability of the final latexes proved outstanding combination of polymerization procedure and surfactants. morphological studies revealed by tem, sax and xrd showed three structures of core-shell, arm...

A model using nanospheres to allow the simulation of the nonspecific interaction of nanobacteria (NB), one with another or with body tissues, is established. Depending primarily on their concentrations and stress levels, these apatite nanovesicles may nucleate thrombogenic conglomerates in blood, or self-assemble to dense nanoclay layers on surfaces in the body. Partial or total encapsulation o...

Nature is full of various nanomaterials and nanostructures that have inspired helped human life civilization in the advancement science technology. Among these materials are clays, which abundantly found rocks earth structures. The mineral montmorillonite, known as a clay nanoparticle, major phase bentonite. This nanoclay, with thickness about 10 angstroms, includes unique properties such expan...

Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on the polypropylene matrix was investigated in terms of mechanical properties of ...
