Temperature and Stress Controlled Surface Manipulation in NiAl Nano-Layers

Sutrakar V.K., Roy Mahapatra D., Melnik R.V.N., Indian Institute of Science, IN

Quantum dot arrays with precisely controlled positions and sizes are desirable for making templates for micro-and nano-electronic devices. Numerous experimental works have shown that unguided self-assembled growth of quantum dots usually fails to realize perfectly [...]

Wicking Study of Nanostructured Titania Surfaces for Flat Heat Pipes

Ding C., Bogorzi P., Sigurdson M., Soni G., Meinhart C., MacDonald N.C., university of california, santa barbara, US

We report a wicking material based on nanostructured TiO2 (NST) for the application of flat heat pipes. This wicking material is formed by oxidizing Ti pillar structures in H2O2 solution. The NST surfaces shows nano-scale [...]

Functional Polymer Micro- and Nanostructures by Nanoimprint

Cheng X., Park H., Cui D., Texas A&M University, College Station, US

We present here the patterning of polymer micro- and nanostructures by nanoimprint technique. Since its inception, nanoimprint has gained huge interest as a high-resolution and low-cost lithography technique for microelectronic fabrication. We demonstrate that nanoimprint [...]

Morphological variations on titanium by AC anodizing

Diamanti M.V., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Besides the widely investigated photoinduced properties of its oxides, a primary branch of application of anodized titanium is the production of biomedical implants, where a controlled roughness can lead to improvements in cell adhesion and [...]

Antibacterial activity on Polyamide and Natural fabrics using Low Temperature Plasma

Shahidi S., Rashidi A., Wiener J., Ghoranneviss M., I.A. University, IR

Polyamide (PA) synthetic textiles are among the most used fibers in the biomedical textile field [1]. Wounds often provide a favorable environment for the colonization of microorganisms. In order to improve the opportunity for wound [...]

Ordered mesoporous films of TiO2 as highly efficient photocatalysts for clean environment

Rathousky J., Kalousek V., Walsh C., J. Heyrovsky Institute of Physical Chemistry, CZ

Photocatalytic oxidation is a promising technology for the purification of air. Providing the surfaces of objects with a finish which is photocatalytically active and exhibits stable illumination-induced superhydrophilicity, is a promising route how to render [...]

Photoactivity of nitrogen-doped anodic TiO2 under UV and VIS light irradiation

Diamanti M.V., Ormellese M., Pedeferri M.P., Politecnico di Milano, IT

Titanium dioxide is probably the most efficient among the known photocatalysts, and undoubtedly the most studied one. An appealing route to tune obtain TiO2 films morphology and structure is to exploit the anodizing process to [...]

Super-hydrophobic and/or Super-hydrophilic Surfaces Made by Plasma Process

Chen L., Henein G., Liddle J.A., National Institute of Standards and Technology, US

Superhydrophobic and superhydrophilic surfaces are generally made by modifying the surface with chemistry and introducing roughness or patterns on surfaces. The processes are generally complex and time-consuming. In this paper, we introduce a simple and [...]

Rapid Synthesis of Anti-Fogging Coatings

Tricoli A., Righettoni M., Pratsinis S.E., Swiss Federal Institute of Technology, CH

The wetting properties of surfaces are fundamental properties greatly influencing their interaction with the environment. Self-cleaning, bacteria-resistant, and anti-fogging surfaces are feasible by depositing either super-hydrophobic or super-hydrophilic coatings and will have great impact on [...]
