Nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. Synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. Solvent casting method was used to prepare Cobalt oxide (Co3O4) dispersed Poly (methyl methacrylate) (PMMA) nano composite<span style="text-decoration: und...

Graphene oxide (GO) has been demonstrated as a nanostructure growth-directing template for the synthesis of fusiform zirconia nanostructures on GO planes. The obtained fusiform zirconia-GO hybrid composites (FZGO) have good dispersion ability and show highly selective capture of phosphopeptides from complex peptide mixtures.

The highly reduced graphene oxide using solvated electrons as reductive agents shows low defects and well dispersion that are vital as the support of Pt nanoparticles in direct methanol electro-oxidation. The electrochemical experiments demonstrate that the Pt/RGO composites not only greatly enhance the catalytic activity but also dramatically improve the durability of the catalyst.

In this experimental study, graphene oxide-blended glass-filled nylon (GO-GFN) hybrid nanopolymer composites were developed and characterized. Transmission electron microscopic studies performed to study the dispersion of oxide in composites. Dynamic mechanical analysis thermogravimetric analyses conducted on fabricated analyze thermal stability. Mechanical properties investigated by tensile te...

Many polymers and composites have been used to prepare active wound dressings. These materials have typically exhibited potentially toxic burst release of the drugs within the first few hours followed by a much slower, potentially ineffective drug release rate thereafter. Many of these materials also degraded to produce inflammatory and cytotoxic products. To overcome these limitations, composi...

The synergistic adsorption of heavy metal ions and humic acid can be very challenging. This is largely because of their competitive adsorption onto most adsorbent materials. Hierarchically structured composites containing polyethylenimine-modified magnetic mesoporous silica and graphene oxide (MMSP-GO) were here prepared to address this. Magnetic mesoporous silica microspheres were synthesized ...

A versatile, eco-friendly synthesis scheme was developed to fabricate a series of hierarchically-structured CuBi2O4 composites for environmental applications. By simple tuning of the synthesis protocol (i.e. controlling the ethylene glycol to water ratio in the reaction matrix and employing different auxiliary metal precursors consisting of Cu(2+), Co(2+) or Fe(3+) species), deposition of vario...

Composite materials, which can optimally use the advantages of different materials, have been studied extensively. Herein, hybrid tungsten nitride and oxide (WN/WO3) composites were prepared through a simple aqueous solution route followed by nitriding in NH3, for application as novel sensing materials. We found that the introduction of WN can improve the electrical properties of the composites...

It has been reported that bacteria-mediated degradation of contaminants is a practical and innocuous wastewater treatment. In addition, iron oxide nanoparticles (NP) are wastewater remediation agents with great potentials due to their strong adsorption capacity, chemical inertness and superparamagnetism. Therefore, a combination of NPs and microbes could produce a very desirable alternative to ...

Over 40% of high-purity silicon (Si) is consumed as sludge waste consisting of Si, silicon carbide (SiC) particles and metal impurities from the fragments of cutting wire mixed in ethylene glycol based cutting fluid during Si wafer slicing in semiconductor fabrication. Recovery of Si from the waste Si sludge has been a great concern because Si particles are promising high-capacity anode materia...
