Abstract: Multifunctional “smart” nanostructures are disclosed that include fluorescein isothiocyanate (FITC)-encapsulated SiO2 core-shell particles with a nanoscale ZnO finishing layer, wherein an outer ZnO layer is formed on the SiO2-FITC core. These ˜200 nm sized particles showed promise toward cell imaging and cellular uptake studies using the bacterium Escherichia coli and Jurkat cancer cells, respectively. The FITC encapsulated ZnO particles demonstrated excellent selectivity in preferentially killing Jurkat cancer cells with minimal toxicity to normal primary immune cells (18% and 75% viability remaining, respectively, after exposure to 60 ?g/mL) and inhibited the growth of both gram-positive and gram-negative bacteria at concentrations ?250-500 ?g/mL (for Staphylococcus aureus and Escherichia coli, respectively).

Abstract: A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is used to coat an article in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may include of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve barrier properties. A desiccant material may also be included or added as a separate layer.

Abstract: A roll cover of the invention is a tubular roll cover made of a thermoplastic fluoropolymer for covering a round rod-like or cylindrical roll body, wherein the thermoplastic fluoropolymer contains from 0.5 to 5% by weight of a carbon nanotube. Since the thermoplastic fluoropolymer thus contains from 0.5 to 5% by weight of the carbon nanotube, the roll cover of the invention can secure necessary conductivity, in other words, have low chargeability of static electrification, secure good antistatic property and prevent an offset phenomenon by static electrification. Further, flexibility, mold releasability, surface cleanability and the like inherent in an ordinary fluoropolymer can be maintained well.
