Chemical and Phase Transformations of Nanocrystalline Oxides in a Carbon Nanoreactor

Volodin A.M., Zaikovskii V.I., Bedilo A.F., Klabunde K.J., Boreskov Institute of Catalysis, RU

The application of nanocrystalline oxides as precursors for synthesis of new nanomaterials with the preservation of the dimensions of the initial nanoparticles is of considerable interest. Its main problem is the sintering and growth of [...]

Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was examined using the scanning electron [...]

Thin-Film Deposition on Nanoparticles in Low-Pressure Plasma

Shahravan A., Matsoukas T., The Pennsylvania State University, US

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

Maki G., Maki W., Mishra N., Fellegy M., Cameron E., Maki G., Maki W., University of Idaho, US

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

Stein B.E., Bujanda A.A., Strawhecker K.E., Pappas D.D., U.S. Army Research Laboratory, US

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 [...]

Production Technology for Nanofiber Filtration Media

Maly M., Petrik S., ELMARCO, CZ

The theoretical background and technical capabilities of the free liquid surface (nozzle-less) electrospinnig process is described. The process is the basis of both laboratory and industrial production machines known as NanospiderTM and developed by Elmarco [...]

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 [...]
