Innovative Use of Ultrasound in the Production of High-Performance Coatings

Hielscher K., Hielscher Ultrasonics GmbH, DE

The metal oxide nanoparticles include nano-sized zinc oxide, titanium oxide, iron oxide, zirconium oxide and cerium oxide, as well as mixed metal compounds, such as indium tin oxide, zirconium and titanium. For the color, paint [...]

Injectable Glucan/Alginate/poly(γ-glutamic acid) Gel for Bone Formation and Differentiation

Lai W.-F.T., Yang M.-C., Su T.-L., Kuo Y.-L., Kung F.-C., Kainan University, TW

Aqueous mixture of β-glucan, alginate and calcium form poly(γ-glutamic acid)(Ca-PGA) was compared with the traditional hydrogels cross-linking with calcium chloride and sodium form γ-PGA (Na-PGA). The suitable proportion by investigating the characters of swellability, pH [...]

Modelling the spectral reflectances of Sol-Gel tin doped indium oxide and aluminium doped zinc oxide coatings

Wolf N., Gerstenlauer D., Manara J., Bavarian Center for Applied Energy Research, DE

In this work it is shown that it is possible to model the spectral reflectances of tin doped indium oxide (ITO) and aluminium doped zinc oxide (AZO) Sol-Gel functional layers with different numbers of single [...]

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

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 [...]
