Highly Stable and Oppositely Charged Hybrid Nanoparticles/Tubes. Fine Tuning of Electro-steric interactions To Fabricate Functional Surfaces

Sekar S., Feltrin E., Giermanska J., Berret J.-F., Chapel J.-P., Centre de Recherche Paul Pascal, FR

Hybrid Functional Surfaces were generated via the novel surface functionalization pathway named Surface Grown Layers (SgL),where the hybrid layers are generated in a single step at a fluid/solid interface via fine tuning of electrostatic complexation [...]

Understanding the Biological Impact of Nanoengineered Surfaces

Casey B.J., Kumar G., Petrochenko P., Skoog S.A., Narayan R.J., Goering P.L., Dair B.J., U.S. Food and Drug Administration, US

There is a growing trend in the medical device industry to manipulate the surface topography of a device with nanoscale features in order to promote advantageous biological responses such as better tissue integration and/or faster [...]

Omniphobic Coatings for Self Cleaning and Enhanced Chemical/Biological (CB) Agent Protective Clothing

Truong Q.T., Koene B.E., US Army Natick Research, Development, and Engineering Center, US

An omniphobic coating that employs a dual hierarchical micro and nano surface structure was developed. This dual-size structured omniphobic coating was proven to be more durable than the commercial durable water repellant coating such as [...]

Superhydrophobic and Superhydrophilic Surfaces

Herzog M.B., Johnston J.H., Franzreb M., Victoria University of Wellington, NZ

A new generation of materials possessing a wide range of possible consumer applications such as water harvesting, stain resistant self-cleaning and water-repellent breathable surfaces are being fabricated. Based on nature’s example of the stenocara beetle, [...]

Effect of superhydrophobic nanocomposite surface roughness on anti-icing performance

Davis A., Yeong Y.H., Steele A., Loth E., Bayer I.S., University of Virginia, US

While past work has shown the ice-phobic potential of a superhydrophobic surface or noted the effect of surface area on ice adhesion to an array of microposts, questions still remain on the effect of a [...]

1D Multi-Structured Micro/nanomaterials with Special Wettability

Zhao Y., Beihang University, CN

With the progresses in material sciences, the generation of microscopic materials experiences an architectural evolution process from simple to complex. The complex interior structures will enable such materials a number of potential applications. Here we [...]

Large scale Eco-friendly Synthesis of Nanoparticulate Fillers for Corrosion Resistant Vinyl Coatings

Radhakrishnan S., Sonawane N., Maharashtra Institute of Technology, IN

The paper describes eco-friendly / green route for large scale synthesis of nanoparticulate additives such as calcium carbonate, iron oxide, barium sulphate etc. which as used for coating applications. The synthesis is carried out using [...]

Optical band gap energy of Er-doped TiO2 thin films

Lee D.Y., Lee I.G., Park J.H., Kim Y.H., Lee D.Y., Lee I.G., Daelim University, KR

Er-doped TiO2 thin films(0~1.0 mol% Er) having a thickness of 400 to 1200 nm were spin coated onto FTO glass substrate by varying PVP concentration. The optical properties of thin films was examined by glancing [...]

Nanopatterning planar and non-planar mold surfaces for a polymer replication

Cech J., Pranov H., Kofod G., Matschuk M., Murthy S., Cheong L.Y., Taboryski R., Technical University of Denmark, DK

We present a novel process to create nanopatterns on planar and non-planar polymer replication tools, such as metallic molds for an injection molding. Such tools with nanopatterned cavities then allow affordable mass production of nanopatterned [...]
