The popularity of running and consequently of running injuries has increased tends to develop shoe sole constructions aiming at preventing different injuries. The purpose of this study was to investigate the effect of shoe outsole containing nanoclay particles on knee joint power during stance phase of running. Fourteen healthy male shod runners run 3 times at 3.5 m.s-1 under three shoe condi...

Nanofibers mats of chitosan (CTS)/polyvinyl alcohol (PVA)/halloysite nanoclay and drug loaded CTS/PVA/halloysite nanoclay//3-glycidyoxypropyl trimethoxysilane were fabricated using the electrospinning method. Electrospun nanofiber samples characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA). FTIR confirmed chemical...

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...

Abstract Hydrogel composites comprised of N,O carboxymethyl chitosan crosslinked with different weight ratios acrylic acid and fabricated nanoclay particle were prepared via gamma irradiation at 25 kGy dose. The coded as CsAA 1 Cl, 2 Cl 3 based on the ratio to derivative. claimed hydrogels characterized by FTIR, TGA XRD. data implied that incorporation clay nanoparticles enhanced thermal stabil...

Abstract The effect of process parameters on the final properties a poly-lactic acid (PLA) and polyhydroxybutyrate (PHB) polymer blend filled with nanoclays was evaluated. To this aim, nanofilled processed in co-rotating twin screw extruder, considering three different profiles values rotation speed, thermal thermo-mechanical so-obtained materials were investigated. Furthermore, XRD analyses, S...

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...
