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 [...]
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 [...]
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 [...]
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 [...]
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 [...]

The paper presents a novel technique that combines anodization and glancing angle sputtering deposition to generate nanorods of Aluminum. The nanorod surface coated with a monolayer of a silane exhibited contact angle of 155 degree [...]
A new durable super-hydrophobic coating has been invented that protects cell phones and other portable electronic products from water or other liquid damage. The printed circuit boards of these consumer oriented products are placed into [...]
We quantitatively report the experimental super-wetting results of wicking materials fabricated with bulk titanium micromachining, nano-scale surface modification and gold plating techniques. The results show all the four samples are completely wettable with water but [...]
Self-assembly of metallic nanoparticles were investigated for the development of field-enhanced chemical and biological detection devices with the capacity to achieve single-molecule level detection resulting from surface enhanced Raman scattering, associated with closely spaced noble [...]
Medical devices have relied to a large extent on silicone oil surface treatment. A drawback of silicone oil is that it may induce aggregation of proteins in vivo or in vitro. The conformational change of [...]
Transparent conducting films of antimony-doped tin oxide (ATO) with a uniform 3D-mesostructure were prepared by self-assembly of crystalline ATO nanoparticles with various antimony content directed by commercially available Pluronic copolymers. The mesostructure of the films [...]
Due to their good mechanical properties as well as high temperature oxidation resistance, multi element oxynitride thin films have attracted more attention for applications in cutting and forming tools. Nanocomposite coatings represent a new generation [...]
To enhance solar energy efficiency of a dye-sensitized solar cell (DSSC), high crystallinity mesoporous TiO2 hollow spheres (MHS-TiO2) have been coated on the photoanode. The MHS-TiO2 was prepared by calcination of the Ti(OBu)4 coated mesoporous [...]
We investigated the effectiveness of electronic properties with single-walled carbon nanotube through spontaneous redox-reaction between the metal oxide ion such as MnO4- and carbon nanotube. The SWCNTs synthesized by the arc discharge method were used. [...]
