Unusually active and sinter-resistant nanocomposite materials were synthesized by combining the high reactivity of nanosized noble metal particles with the excellent hightemperature stability of hexa-aluminates through a simple one-step microemulsion-templated sol-gel synthesis. The novel nanocomposite [...]
This paper describes the preparation and properties of an inorganic membrane with permeability for H2 comparable to palladium and with over 99.9% selectivity over larger species like CO, CO2 and CH4. The membrane is a [...]
The characterisation of the association of an alternating copolymer was performed using theoretical methods (quantum mechanics and molecular mechanics) and experimental methods (cryo-Transmission Electron Microscopy, Neutron Reflectivity and Neutron Scattering). The most stable conformation obtained [...]

A range of multi-wall carbon nanotubes and carbon nanofibres were mixed with a polyamide-12 matrix using a twin-screw microextruder, and the resulting blends used to produce a series of reinforced polymer fibres. The aim was [...]
In the present work we explore a new type of nanocom- posite, in which clay is distributed in a multi-phase polymer system. Our nanocomposites consist of an immiscible polymer pair, polypropylene grafted with maleic anhydride [...]
We have demonstrated a hybrid coating consisting of both a stratified layer that incorporates corrosion inhibiting ions and a silicate barrier layer. The stratified layer is applied to the aluminum alloy using the layer-by-layer assembly [...]
Superplastic deformation behaviour is now well established in fine-grained zirconia ceramics at fairly high temperatures (well above 0.5Tm, where Tm is the absolute melting point). In this study, an attempt was made to develop a [...]
Spinel particle/organic hybrids were succsessfully synthesized from metal-organics below 100oC. Chlated iron- (iron allylacetylacetonate) and nickel-organics were used as starting materials. Two nickel-metal organics (nickel acetylacetonate (NA) and nickel diammine propenylacetylacetonate (NPA)) were investigated. The [...]
Extensive research has been focused on the processing of carbon nanotubes polymeric composites. The ability to impose a preferred alignment of carbon nanotubes in a composite will increase the effectiveness of utilizing nanotubes in composite [...]
Room temperature cure Epoxy resin has been doped with SiC nanoparticles through an ultrasonic cavitation process. The modified resin is then utilized in a Vacuum Assisted Resin Transfer Molding (VARTM) process with satin weave carbon [...]
Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The [...]
Nanoparticles can be incorporated into polymeric coatings to enable significant improvement in targeted properties, i.e., scratch resistance, UV resistance, conductivity, etc. Commercial processing methods have been developed to surface treat nanoparticles to render compatibility between [...]
Sustainable 'green' nanocomposites were successfully fabricated from cellulose acetate (CA), triethyl citrate (TEC) plasticizer and organically modified clay. Maleic anhydride grafted cellulose acetate butyrate (MA-g-CAB) was used as a compatibilizer. The effect of compatibilizer proportions [...]
A homogeneous non-aqueous solution reactions method has been developed to prepare gold-coated cobalt (Co@Au) nanoparticles. After the sample was washed with 8% HCl, TGA, XRD, TEM, and magnetic measurements SQUID are utilized to characterize the [...]
With the recent advances in nano-scale science and engineering, materials containing reinforcement with superior mechanical properties can be found in many advanced products. The accurate prediction of the mechanical properties of this class of composite [...]
Nano-composites are important class of materials because of many of their physical and chemical properties show particle size dependence. Nano-structured metal (Zn, Mg, Ca) aluminate, with spinel structure, dispersed in SiO2 glassy matrix materials are [...]
