Synthesis and Electrical Characterization of Silicon Nanoparticles for Electronic Applications

Gopireddy D., Takoudis C.G., Gamota D., Zhang J., Brazis P.W., University of Illinois - Chicago, US

In an effort to assess their potential for future nanoelectronic devices, we have fabricated silicon nanoparticles field effect transistors with nanoparticles as the active channel. The nanoparticles of 10-20 nm diameters are grown on a [...]

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
