Development of Durable Nanostructured Superhydrophobic Self-Cleaning Surfaces in Glass Substrates

Jiang Y.D., White M., Hunt A.T., Kitada M., Fitz T., nGimat Co., US

Superhydrophobic self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. Many existing hydrophobic coatings either have low transmittance which is not suitable for windows or not as hydrophobic as lotus [...]

Fabrication of superhydrophobic nanostructured films by Physical Vapour Deposition

Yoldi M., García J.A., Rodríguez R.J., Rico M., AIN, ES

This work reports on recent advances in the deposition of non-wettable coatings with high water contact angles (WCAs). We propose a simple and easily-controlled method for fabricating different types of nanoestructured films with hydrophobic properties [...]

NanoZeolites – small particles, small pore, big impact! Porous nanoparticles for environmental applications

Daniell W., Kohl A., Sauer J., NanoScape AG, DE

NanoScape has developed hydrothermal synthesis techniques which allow nanocrystalline, porous aluminosilicates (NanoZeolites) to be manufactured, currently on a 100kg p.a. scale. A range of NanoZeolites are available with pore sizes ranging from 3A to 100A. [...]

A Generalised Approach for the Surface Engineering of Nanoparticles in Suspension for Highly Efficient Hybrid Capture of Bio-molecules

Sen T., Bruceb I.J., University of Central Lancashire, UK

A generalised method of surface engineering of nanoparticles in suspension has been reported using a novel strategy “Tri-phasic reverse Emulsion” or TPRE. In this method, the surface functionalisation of nanopaticles can be controlled by controlling [...]

Magnetite nanoparticles as moderators of extreme conditions during Bradyrhizobium japanicum growth

Ghalamboran M.R., Ramsden J.J., Cranfield University, UK

The aim of this study was to investigate whether magnetite nanoparticles and pH simultaneously affect Bradyrhizobium growth rate (BGR) in liquid media, with a view to diminishing sensitivity to high pH and, hence, enhancing survival [...]

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 [...]

Preparation and Characterization of BiFeO3 Nanosystems as Visible Light Driven Photo-degradation of Organic Compounds

Hengky C., Dunn S., Singh V., Loh L., Nanyang Polytechnic, SG

The use of renewable or low energy sources for the degradation of organic pollutants has generated broad interest in both scientific research and potential applications in recent years. Research on semiconductor photocatalysis came sharply into [...]

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 [...]

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 [...]

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.
