A Markedly Cntrollable Adhesion of Superhydrophobic Sponge-like Nanostructure TiO2 Films

Lai Y., Lin C., Huang J., Zhuang H., Sunb L., Nguyen T., Xiamen University, CN

A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]

Hypertransparent Nanostructured Superhydrophobic Self-Cleaning Coatings on Glass Substrates

Jiang Y.D., Smalley Y., Paris H., Hunt A.T., nGimat Co., US

Self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. The development of superhydrophobic surfaces was inspired by observation of lotus and other plant leaves. Many existing hydrophobic coatings either have [...]

Engineering superhydrophobic and superoleophobic surfaces

Tuteja A., Choi W., Mabry J.M., McKinley G.H., Cohen R.E., Massachusetts Institute of Technology, US

The combination of surface chemistry and roughness on multiple scales imbues enhanced repellency to the lotus leaf surface when in contact with a high surface tension liquid such as water. This understanding has led to [...]

Nanostructured thin layers of vanadium oxides doped with cobalt, prepared by pulsed laser ablation: structure, chemistry, morphology, and magnetism

Teodorescu C.-M., Socol G., Negrila C., Luca D., Macovei D., National Institute of Materials Physics, RO

The present study deals with cobalt-doped vanadium oxide thin layers prepared by pulsed laser ablation. Variation of the preparation parameters allows one to synthesize films with a variety of properties. The chemical composition of the [...]

Surface Nanostructuration: from coatings to MEMS fabrication

Pugin R., Blondiaux N., Popa A.M., Klein M., Montagne F., Scolan E., Hoogerwerf A., Overstolz T., Liley M., Giazzon M., Weder G., Heinzelmann H., Centre Suisse d’Electronique et de microtechnique, CH

The fabrication of surfaces and films with controlled nanometer features is currently an active area of research. The design of complex nanoarchitectures with novel physical properties has potential applications in many existing and emerging fields [...]

Biofunctional core-shell nanoparticle deposition for biochip creation by printing processes

Borchers K., Weber A., Genov S., Wirth I., Grzesiak A., Tovar G.E.M., Fraunhofer Institute for Interfacial Engineering and Biotechnology, DE

Nanoparticles display a very large surface-area. Therefore, coatings of functional nanoparticles adsorbed to a solid substrate yield an enlarged interface per footprint-area which is highly appreciated for probe-immobilization in bio-chip technology [1,2]. Silica nanospheres, equipped [...]

Innovative PMMA/CaCO3 Nanocomposites

Avella M., Errico M.E., Gentile G., INSTITUTE OF POLYMER CHEMISTRY AND TECHNOLOGY - CNR, IT

Innovative poly(methyl methacrylate) based nanocomposites filled with two kinds of calcium carbonate nanoparticles, coated with stearic acid and poly(butyl acrylate), were prepared. The influence of the nanoparticles nature and content on the chemical-physical properties of [...]

Gold Composite- and Macroporous Gold Nanoparticle Films by a Vertical Deposition Method

Badilescu S., Kahrizi M., Ashrit P.V., Truong V-V, Concordia University, CA

Composite films have been prepared in one step by a vertical deposition method from the aqueous suspension of gold colloids and polystyrene (PS) microspheres. The composite is formed on a glass substrate by convective assembly [...]

Morphological Consequence of Sonication on Lignin-CNT-Epoxy Composite

Thomas D., Edwards J., Parker R., Ku C.-L., Bryan D., Liao Y-H, Liang R., Florida A & M University, US

This project will utilize SEM and molecular modeling analysis to determine morphological consequences of presonication time on lignin particle size and the joint sonication of lignin with CNT. The investigation will yield a more fundamental [...]
