Effects of Surface Texture and Chemistry on Surface Hydrophobicity and Oleophobicity

Law K-Y, Zhao H., Sambhy V., Xerox Corporation, US

The effects of surface texture and chemical modification on the hydrophobicity and oleophobicity of the resulting surfaces have been systematically investigated. The surface textures were created by the conventional photolithographic technique on Silicon wafer. This [...]

Properties of a Newly Developed Carbon-Aluminum Nanocomposite

Yang M., Novak J., Fink R., Brookover J., Jiang N., Applied Nanotech, Inc., US

A unique carbon-based metal nanocomposite comprised of 80% carbonaceous matrix and a dispersed metal component of 20% aluminum material, represents a culmination of efforts in material science and manufacturing processes focused on the advancement of [...]

Permittivity of BaTiO3 polymer composite with differing particle size distribution

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe GmbH, DE

In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]

Rheology, Microstructure, and Property of Polylactide/Clay Nanocomposites Prepared with SC-CO2 by Melt Compounding

Jiang G., Chen Z.K., Huang H.X., South China University of Technology, CN

The rheology, microstructure and mechanical properties of polylactide (PLA)/clay nanocomposites were investigated. The nanocomposites were prepared using a twin screw extruder with and without the aid of supercritical carbon dioxide. Results show that there exists [...]

Using Nanoparticles and Carbon Nanotubes to Enhance the Properties of a Lead-free Solder

Nai S.M.L., Han Y.D., Jing H.Y., Tan C.M., Wei J., Gupta M., Singapore Institute of Manufacturing Technology, SG

Solders are used in various levels of electronic assembly sequence, whereby good electrical, thermal and mechanical performances of solder are necessary. With miniaturization of devices, diverse functional requirements and ever-stricter operating environments of devices, the [...]

Nano-Engineered Dielectrics for Energy Storage Solutions

Badi N., Bensaoula A., University of Houston, US

We present a novel laser processing technique to produce nanodielectric films, which are based on polymer coated metal nanoparticles. The polymer-coated Au NP composite was spin-coated onto a nickel foil serving as the bottom electrode [...]

ROMP of norbornene catalysed by Grubbs functionalized carbon nanotubes

Longo P., Costabile C., Grisi F., Siniscalchi G., Ciambelli P., Sarno M., Leone C., Sannino D., University of Salerno, IT

Recently, carbon nanotubes have attracted attention for their unique structural and electronic properties, which position them as one of the leading materials for a wide array of potential nanotechnological applications. The synthesis of homogeneuos polymeric [...]

Determination of Elastic and Thermal Properties of Nanocomposites by Fiber Embedment in Finite Elements

Spanos P.D., Esteva M., Akin J.E., Rice University, US

In this paper the impact of entangled and non-straight fibers in the determination of the effective elastic and thermal properties of polymer nanocomposite (PNC) is addressed. Most of the models in recent studies assume nanotubes [...]

Extraction of Bulk Material Properties from Phonon Dispersion Spectra

Kumar N., Pochiraju K., Stevens Institute of Technology, US

Experimental characterization of mechanical behavior of nanostructures can be cumbersome and expensive. Design of nano-structured materials with properties tailored to meet macro-scale requirements invariably requires model-based understanding of the structure-to -property relationships. In this effort, [...]
