Thin-Film Deposition on Nanoparticles in Low-Pressure Plasma
To achieve the desirable optical, mechanical, thermal, and electrical properties that are unattainable in the nanoparticles alone, Matsoukas group uses plasma enhanced chemical vapor deposition technique, PECVD. Particles are introduced into two different reactors that [...]
An experimental and theoretical study of the inhibition mechanism of organic substances in concrete
Diamanti M.V., Ormellese M., Perez-Rosales E.A., Pedeferri MP., Raffaini G., Ganazzoli F., Politecnico di Milano, IT
Corrosion inhibitors are one of the preventative techniques used to prevent chloride-induced corrosion in reinforced concrete structures. Several commercial inhibitors are available on the market, but their efficiency as well as their inhibitive mechanism are [...]
Chemical structure of ZnO nanorod array on a DSSC photoanode
Chang Y-H, Liao C-Y, Wang H.P., Wei Y-L, Fukushima Y., Guo T-F, Chiang Y-F, National Cheng Kung University, TW
The main objective of the present work was to study speciation of ZnO nanorods and the photoexcited electron transfer between photosensitive dyes and the ZnO nanorod arrays (Fig. 1) on the photoanode of a dye-sensitized [...]
Bio-Molecules Immobilization on Nanowire Electronic Devices
Nano-scale Field Effect Transistor based devices (nano-FETs) have shown great promise in bio-molecular detection. The advantages of using electronic nano-devices verses using conventional bio-detection methods are: direct detection without labeling, ultra-sensitivity without amplification and simple [...]
Atmospheric Plasma Surface Modification of Polytetrafluoroethylene Films for Metal Deposition
This work details the use of atmospheric-pressure dielectric barrier discharge plasmas to enhance the adhesion of thin metal coatings to PTFE films. Differences in energetic plasma species have a pronounced effect on resulting wettability. Increased [...]
The Nanophysics of TiO2/Au Model Catalyst as a Key to Understanding the High Efficiency of Real Au/TiO2 Catalyst and Technological Consequences
Tvauri I.V., Remar D.F., Turiev A.M., Tsidaeva N.I., Fukutani K., Magkoev T.T., University of North Ossetia, RU
Interaction of carbon monoxide and oxygen on the surface of titania/Au(111) inverse model catalyst held at 200 K has been studied by a set of surface science techniques. It was found that CO adsorbs on [...]
Simple Fabrication of Hierarchical Structures on a Polymer Surface
In this study, inspired by multiscale structures found in nature like lotus leaf we will try to make multiscale structures on polymer surfaces to make their surface superhydrophobe. We introduce a novel and effective method [...]
Fabrication and assembly of nanowrinkle patterns on metallic surface: a nonlithography method for nano fabrication
Ordered periodic nanostructures have shown its great importance in both fundamental research and practical use. Motivated by wrinkles, which are ubiquitous in nature, artificial patterns with micro periods were fabricated in stiff/soft bilayer. Compare to [...]
