Ceramic composites based on alumina and zirconia have found a wide field of application in the present century orthopedic joint replacements, their use dentistry is spreading. The development this class bioceramic was started 1980s, but first clinical applications total hip replacement were introduced market only early 2000s. Since then, several composite systems replacements. These materials a...

The structure and electrochemical characteristics of composites based on multi-walled carbon nanotubes (MWCNTs) manganese oxide with the addition rhenium has been studied. It shown that decorating MWCNT surface layers or nanoparticles (Mn(III) + Mn(IV)) provides more than a twofold increase in value specific capacitance at low potential scan rates. However, only exhibit poor behavior decreases ...

In this paper the role of super paramagnetic iron oxide nanoparticles (SPI) on Platinum nanoclusters on activated carbon (Pt/C) for electrocatalytic oxygen reduction reaction was considered. Four composites of Pt/C and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of Pt/C (1.2, 0.6, 0.4 and 0.3 mg ). The composite attached ...

We report a simple yet versatile method to simultaneously achieve the exfoliation and reduction of graphite oxide. By treating graphite oxide powders in a commercial microwave oven, reduced graphite oxide materials could be readily obtained within 1 min. Extensive characterizations showed that the as-prepared materials consisted of crumpled, few-layer thick and electronically conductive graphit...

The preparation of graphene/apatite and graphene oxide/apatite hybrid nanocomposites has recently attracted great attention in the biomaterial community. sitting drop vapor diffusion technique been assessed as a preparative method for such this work. employed to induce heterogeneous nucleation growth calcium phosphate presence exfoliated commercial oxide flakes, both labeled with L-Alanine. Exf...

We propose a novel approach of wet electrospinning to yield fiber-reinforced polymer ceramic composites, where reactive precursor gel is used as collector. illustrate our by generating polyethylene oxide (PEO) fibers in potassium silicate gel; the later activated using metakaolin ceramic-0.5 wt% PEO fiber composite. An increase 29% and 22% recorded for fabricated composites terms indentation mo...

Liquid epoxy resins have received much attention from both academia and the chemical industry as eco-friendly volatile organic compound (VOC)-free alternatives for applications in coatings and adhesives, especially in those used in households. Epoxy resins show high chemical resistance and high creep resistance. However, due to their brittleness and lack of thermal stability, additional fillers...

The effects of transition metals on the hydrophobicity of nano–structured layered double hydroxides (LDHs) and the compatibility of LDHs/ethylene vinyl acetate (EVA) composites have seldom been reported. NiMgAl–LDHs slightly surface–modified with stearate and doped with transition metal cations (Mn2+, Co2+, Cu2+, Zn2+) are investigated. Compared to the pure EVA, not only were the maximal degrad...

Metal–organic frameworks/graphene oxide in situ composites are promising candidates for the CO2 capture microwave swing adsorption process.
