Tribological studies of conventional microcrystalline and engineered near-nanocrystalline WC-17Co HVOF coatings

Saha G., Mateen A., Khan T., University of Calgary, CA

Tungsten carbide based cermet composite coatings possess the unique surface protection properties enabling their increasing use in the oil sands industry to combat severe sliding and high stress abrasion wear and other types of slurry [...]

Nanopowders of TiO2 obtained by combustion reaction: effect of fuels

Almeida E.P., Coutinho J.P., Freitas N.L., Kiminami R.H.G.A., Costa A.C.F.M., Lira H.L., Universidade Federal de Campina Grande, BR

The synthesis by combustion reaction to obtain TiO2 has been studied by several researchers and using different fuels. Thus, this study aimed to evaluate the effect of fuel (citric acid monohydrate, aniline, oxalic dihidrazida and [...]

Nanoscale Silver Coatings on Synthetic Fibers

Amberg M., Körner E., Hegemann D., Heuberger M., Empa, Swiss Federal Laboratories for Materials Testing and Research, CH

In this work, we present two different low-pressure plasma processes that are used to obtain nanoscale coatings on the special geometry of fibers. A 100-200nm thick smooth silver coating is produced and its electromechanical as [...]

Preparation and Application of Copper Oxide Nanoparticles

Chang M-H, Tai C.Y-D, National Taiwan University, TW

The aim of this research was to synthesize copper oxide (CuO) nanoparticles, which were further applied to prepare CuO-water nanofluid, using a spinning disk reactor (SDR). The precursor of copper oxide was first synthesized by [...]

Biofouling control coatings utilizing VOC free biodegradable chitothane and nanotubes containing non-toxic natural product repellents

Price R.R., Matias J., Glen Muir Technologies, Inc., US

Novel water based biofouling control coating based on natural marine polysaccharides and novel naturally occuring nanoscale microcylinders for the delivery of natural antifouling repellent analogs for control of biofouling on surfaces.

Preparation of Silver Nanoparticles via Ionomer Clusters

Atorngitjawat P., Pipatpanyanugoon K., Faculty of science, Burapha University, TH

Silver nanoparticles can be prepared via the cluster of ionomer templates, which is a simple, fast and economical technique. The lower of acid levels of ionomers provided the smaller size of silver nanoparticles. Furthermore, using [...]

Adhesion of Water on Flat Polymer Surfaces and Superhydrophobic Surfaces

Law K-Y, Zhao H., Samuel B., Xerox Corporation, US

The interaction of water droplet with flat polymer surfaces of varying hydrophobicity (contact angle) has been studied using a high-sensitivity microelectromechanical balance system (tensiometer). Both attractive force and pull-off force are studied as the water [...]

A facile low-temperature route for preparing monodisperse Mn3O4 nanopolyhedrons from amorphous MnO2 nanoparticles

Ma J., Zhang S., Liu W., Zhao Y., University of Shanghai for Sci& Tech., CN

In the paper, we firstly show a facile hydrothermal route for synthesizing monodisperse Mn3O4 nanopolyhedrons directly used new-made amorphous MnO2 nanoparticle with its mother solution as precursors. The hydrothermal process was performed at 160 ºC [...]

Transport of large Particles and Macromolecules in Flow Through Inorganic Membrane

Imdakm A.O., Matsuura T., University of Ottawa, CA

The influence of transport of large particles and macromolecules on membrane separation efficiency and permeation rate limitation has been observed in many separation processes of microscopic scale. In this paper a Monte Carlo simulation model [...]
