Dispersing Nanoparticles – The Key to Application

Pilotek S., Tabellion F., Schär S., Steingröver K., Buhler PARTEC GmbH, DE

Inorganic nanoparticles are used in many different branches: e.g. display technology, consumer goods, coatings, plastics, cosmetics, and paper industry use nanoparticles as major components or functional additives. In most applications, the particles are needed in [...]

The Interaction of Protein-Modified Nanodiamond with Bacterial Cells

Perevedentseva E.V., Tu J.-S., Cheng C.-L., Cheng C.-Y., Chung P.-H., Chang H.-H., Cheng C.-L., Cheng C.-Y., National Dong-Hwa University, TW

The possibility of using nanodiamond as bioactive nano-probes for bio-object labeling and treatment is demonstrated. The conjugation of Nanodiamond crystals and bio-molecules are comparatively new but promising subject of interest for bio-applications, due to their [...]

Converting of Nanoparticles in Industrial Product Formulations: Unfolding the Innovation Potential

Schaer S., Arnosti G., Pilotek S., Tabellion F., Naef H., Buhler AG, CH

Potential users of nanoparticles want the particles in a ready-to-use form. The market currently offers practically only raw materials and standard nanoparticles not tailored to a specific application. A newly developed chemo-mechanical converting process for [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

Silicon Surface Modification with Silane-functionalized Polymers

Viswanathan K., Long T.E., Ward T.C., Virginia Tech, US

The synthesis of trimethoxysilane end-capped linear polystyrene (PS), star-branched PS, and subsequent silicon (Si) surface modification with the linear and star polymers are described. Trimethoxysilane terminated PS was synthesized using sec-butyl lithium initiated anionic polymerization [...]

Surface Modification of Al203 Fiber with Nanoparticles Using a Dry Mechanical Coating Technique

Coowanitwong N., Wu C-Y, Nguyen J., Cai M., Ruthkosky M., Rogers J., Feng L., Watano S., Yoshida T., University of Florida, US

Nanoparticles are of great interest to many industries due to their unique properties. One of the well-known properties is high surface area, which is critically essential to enhancing performance activity [1] and greatly vital to [...]

Compositional Inhomogeneity of Pd70Ag30 Alloy Nanoparticles

Wang K-W, Chung S-R, Jang L-Y, Lee J-F, Perng T.P., National Tsing Hua University, TW

The compositional inhomogeneity of Pd70Ag30 nanoparticles with the size of 6-7nm was studied by X-ray absorption near edge structure (XANES). The composition of the as-prepared nanoparticles by chemical reduction is inhomogeneous across the diameter due [...]
