Evaluation of Antibacterial Activities of Zinc Oxide-Titanium Dioxide Nanocomposites Prepared by Sol-Gel Method

Chang H., Leung H., Nanyang Polytechnic, SG

Antibacterial activity of ceramic powders has attracted attention as a new technique that can substitute for conventional methods using organic agents. Ceramic powders of zinc oxide (ZnO), calcium oxide (CaO) and magnesium oxide (MgO) were [...]

Synthesis and Characterization of Novel ZnO-Whey Protein Nanocomposite at Low Temperature

Shi L., Zhou J., Gunasekaran S., University of Wisconsin-Madison, US

The incorporation of nanocrystalline ZnO into whey protein to form nanocomposite will possess the unique functionalities and potential applications in material science and food sciences. Herein we synthesized nanocrystalline ZnO particles coated with whey protein [...]

Mechanical properties under nanoindents in gold nanoparticles reinforced poly(vinyl alcohol) nanocomposite films

Tripathy P., Mishra A., Ram S., Fecht H-J., Indian Institute of Technology, IN

Free standing films of gold nanoparticles reinforced poly(vinyl alcohol) (PVA) nanocomposite are synthesized by a novel chemical method with selective Au-contents varied from 0.1 to 5.0 wt%. The color change in the Au-PVA nanocomposite films [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]

Total flexibility in thin film design using polymer nanocomposites

Druffel T., Buazza O., Lattis M., Farmer S., Optical Dynamics, US

Optically clear, mechanically flexible nanocomposites are created by doping host polymers with nanoparticles having higher or lower refractive indices. The composite materials preserve the viscoelastic properties of the binding polymers and exhibit infinite tunability between [...]

Fabrication of Nano-engineered Composites Reinforced with Carbon Nanotubes (CNTs)

Wicks S.S., Yamamoto N., Guzman de Villoria R., Ishiguro K., Cebeci H., Wardle B.L., Massachusetts Institute of Technology, US

Composites, consisting of aligned advanced fibers embedded in epoxy, are common structural materials used in the aerospace industry for their superior strength to weight ratio and their versatility in tailoring specific mechanical properties, among other [...]

Halloysite Nanotubes in Polymers

Daly R.C., Fleischer C.A., Wagner A.L., Duffy M., NaturalNano, Inc., US

Halloysite Nanotubes (HNT TM) provide a new avenue for the preparation of nanocomposites. These unique tubes can be dispersed by normal extrusion processes in a variety of polymer melts to produce nanocomposites with unusual physical [...]

Advantages and Limitations of Diamond-Like Carbon as a MEMS Thin Film Material

Ohlckers P., Skotheim T., Dmitriev V., Kirpilenko G., Vestfold University College, NO

We can observe from the material properties of Diamond-Like Carbon (DNC) several characteristics can be favourable exploited to make MEMS devices with DNC thin films: Extraordinary yield strength, extraordinary stiffness, high indentation hardness and wear [...]

Improve Contacts in Carbon Nanotube Networks by In situ Polymerization of Thin Skin of Self-Doped Conducting Polymer

Ma Y., Cheung W., Wei D., Bogozi A., Chiu P.L., He H., Rutgers, US

Herein, we report the conductivity of SWNT networks can be dramatically improved by in-situ polymerization of a thin layer of self-doped conducting polymer around and along the carbon nanotubes. The formed conducting polymer improves the [...]

Layer by Layer Fabrication of an Amperometric Nanocomposite Biosensor for Sulfite

Adeloju S.B., Ohanessian A., Water and Sensor Research Group, AU

This paper will present the results of a layer by layer strategy that we have developed for the fabrication of a polypyrrole nanocomposite amperometric biosensor for sulfite. The use of this strategy to fabricate bilayer [...]
