A Novel Synthesis of Co@Au Nanoparticles and Characterization

Ban Z., O'Connor C.J., University of New Orleans, US

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 [...]

Sustainable Nanocomposite Materials from Cellulosic Plastics

Misra M., Park H.M., Mohanty A.K., Drzal L.T., Michigan State University, US

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 [...]

Nanoparticle Composites for Coating Applications

Cayton R.H., Nanophase Technologies Corporation, US

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 [...]

Carbon Nanofiber Reinforced Carbon/Polymer Composites

Joshi M., Bhattacharyya A., Indian Institute of Technology, IN

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 [...]

Synthesis & Mechanical Characterization of Carbon/Epoxy Composites Reinforced with SiC Nano Particles

Chisholm N., Mahfuz H., Rangari V., Rodgers R., Jeelani S., Tuskegee Unviersity, US

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 [...]

Assisted Alignement of Carbon Nanotubes

Haik Y., Chatterjee J., Chen C-J., Bimagnetic Engineering Lab, US

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 [...]

Synthesis of Spinel Ferrite Particle/Organic Hybrid from Metal-Organics

Yogo T., Nakamura S., Sakamoto W., Nagoya University, JP

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 [...]

On the Development of a Nanocrystalline Yttria Stabilised Zirconia Ceramic Capable of Superplastic Deformation at Relatively Low Temperatures

Bhattacharya S.S., Betz U., Hahn H., IIT Madras, IN

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 [...]

Corrosion Protection by Multifunctional Stratified Coatings

Westcott S.L., Kotov N.A., Ostrander J.W., Mamedov A.A., Reust D.K., Roark J.P., Nomadics, Inc., US

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 [...]

Thermal and Morphological Study of a New Type of Nanocomposites: Functionalized PP / PA / Clay Nanocomposites

Oyama H.T., Oono Y., Nakayama K., National Institute of Advanced Industrial Science and Technology (AIST), JP

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 [...]
