Growth Kinetics of Gold Nanoparticles in Reverse Micelles

Herrera A.P., Vicuña E., Rinaldi C., Castro M.E., Irizarry R., Briano J.G., University of Puerto Rico, US

Gold nanoparticles were formed from the reduction of gold (III) in reverse micelles and monitored with a stopped flow analyzer. The gold and the reducing agent micelles were formed in isooctane and AOT (as surfactant). [...]

Nanoparticle Dispersions for Polishing Applications

Murray P.G., Nanophase Technologies Corporation, US

Increasingly, improvements in surface roughness and planarity are being sought in a variety of technologically advanced polishing applications related to the electronics industry. From the production of photomask blanks to the fabrication of microelectronic memory [...]

Adsorption of PTDCA on Si(100) and Si(100)-H

Soubiron T., Vaurette F., Grandidier B., Wallart X., Nys J.P., Stiévenard D., IEMN (UMR8520, CNRS), Dpt ISEN, FR

Submonolayer coverages of perylene-tetracarboxylic-dianhydride (PTCDA) molecules have been investigated with scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). At high coverage, X-ray measurements indicate that only a fraction of the molecules are chemisorbed and [...]

Conjugation of DNA to Streptavidin-coated Quantum Dots for the Real-time Imaging of Gene Transfer into Live Cells

Kim J.K., Lim S.H., Lee Y., Shin Y.S., Chung C., Yoo J.Y., Chang J.K., Digital Bio Technology, Co, KR

We have developed the method for the conjugation of biotinylated DNA to streptavidin-coated quantum dots (QDs). QD-DNA conjugates and a highly sensitive fluorescence imaging technique are adopted to visualize gene transport across the membrane of [...]

Phase Morphology Control in Electrospun Nanofibers From Polymer Blends

Wei M., Kang B., Sung C., Mead J., University of Massachusetts-Lowell, US

Nanofibers of polybutadiene/polycarbonate blends were electrospun from polymer solutions. The effect of composition on the resulting internal morphology of the nanofibers was studied using Transmission Electron Microscopy (TEM). When the composition ratio of PB/PC blends [...]

Controlling the Photoactivity of Nanoparticles

Casey P., Boskovic S., Lawrence K., Turney T., CSIRO(CMIT), AU

The relative photoactivity of a series of nanophase ZnO powders with varying crystallite size (20-140nm) was determined using a chemical method based on the photobleaching behaviour of the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). It was confirmed [...]
