Gold Composite- and Macroporous Gold Nanoparticle Films by a Vertical Deposition Method

Badilescu S., Kahrizi M., Ashrit P.V., Truong V-V, Concordia University, CA

Composite films have been prepared in one step by a vertical deposition method from the aqueous suspension of gold colloids and polystyrene (PS) microspheres. The composite is formed on a glass substrate by convective assembly [...]

Morphological Consequence of Sonication on Lignin-CNT-Epoxy Composite

Thomas D., Edwards J., Parker R., Ku C.-L., Bryan D., Liao Y-H, Liang R., Florida A & M University, US

This project will utilize SEM and molecular modeling analysis to determine morphological consequences of presonication time on lignin particle size and the joint sonication of lignin with CNT. The investigation will yield a more fundamental [...]

Quantum Dot Dissemination and Behavior in Bacterial Biofilms

Morrow J.B., Holbrook R.D., Zeissler C.J., National Institute of Standards and Technology, US

Quantum dots (QDs) are colloidal semiconductor nanocrystals that photoluminescence emission is proportional to the dot size and have been utilized in fluorescent imaging in biological systems. Biofilms are communities of microorganisms attached to surfaces encased [...]

Nylon – Exfoliated Graphite Nanoplatelet (xGnP) Nanocomposites with Enhanced Mechanical, Electrical and Thermal Properties

Fukushima H., Drzal L.T., Michigan State University, US

Since the late 1990’s, research has been underway in our group at Michigan State University to investigate the production, fabrication and modification of a new nano-sized carbon material, exfoliated graphite nanoplatelets [xGnP]. The xGnP is [...]

Aligned Electrospun Nanocomposite Fibers

Nartker S.R., Misra M., Drzal L.T., Research Assistant, US

Electrospun fibers have been used in various applications including filtration media, biomedical, ceramics and composites. Electrospinning uses an electric field to draw a polymer solution jet from the tip of a capillary to a collector [...]

Nanoparticle Surface Treatments – Application Tailored Interfaces

Brotzman Jr. R.W., Murray P.G., Cayton R.H., Nanophase Technologies Corporation, US

Nanophase Technologies Corporation has developed new surface treatment technologies for nanoparticles. The new surface treatments may be applied to a wide range of nanoparticle types and chemistries and enable the nanoparticle interface to be tailored [...]

Polyamide 6-Organoclay- Impact Modifier Nanocomposites

Isik I., Yilmazer U., Bayram G., Middle East Technical University, TR

Polyamide-6, organically modified montmorillonite, and ethylene/glycidyl methacrylate (E-GMA) and ethylene/butyl acrylate/glycidyl methacrylate (E-BA-GMA) terpolymers acting as impact modifiers for polyamide were melt blended in order to investigate the effects of component concentrations on the final [...]

A new system of composites: MWNT-mullite

Wang J., Kou H.M., Xiang C.S., Pan Y.B., Guo J.K., Shanghai Institute of Ceramics, Chinese Academy of Sciences., CN

Carbon Nanotubes (CNTs) are attracting increasing interest as constituents of composite materials for a wide range of applications. MWNT (multi-walled CNT)-ceramics composites are in the beginning of research. The mechanical properties of MWNTs-SiO2 composites were [...]

Surface Modification of Perovskite Manganite Thin Films using Atomic Force Microscopy

Schaefer D.M., Bolling C., Sunderland J., Davidson A., Kolagaani R., Bradley T., Ludka B., Towson University, US

Nanolithography using the atomic force microscope (AFM) is emerging as a promising tool for nanotechnology . We report our results of AFM- induced nanoscale surface modifications in thin films of the CMR manganite material La0.7Ba0.3MnO3. [...]
