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 [...]

Simple Fabrication of Hierarchical Structures on a Polymer Surface

Farshchian B., Hurst S.M., Ok J.T., Park S., Louisiana State University, US

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

Zhang Z., Guo C., Liu Q., National Center for Nanoscience and Technology, China, CN

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 [...]

Control of solid surface properties by electron beam processing

Vasiljeva I.V., Mjakin S.V., Engineering Technology Center RADIANT, Ltd., RU

The effect of electron beam treatment upon various materials (oxides, sulfides, ceramics, polymers) is studied to clarify the general features of chemical reactions involving surface functional groups in correlation with the process parameters. The mechanisms [...]

Rhodamine B degradation efficiency of differently annealed titanium dioxide nanotubes

Diamanti M.V., Stercal F., Pedeferri MP., Politecnico di Milano, IT

This paper presents an investigation over the photoefficiency of nanotubular titanium dioxide films in the degradation of organic pollutants: rhodamine B was chosen as model reactant. The effects of thermal treatments in several atmospheres on [...]

Effect of nano-sized silica particle for high insulation resistance on the surface of non-oriented electrical steel

Kim J.W., Kwon M.S., Han C.H., POSCO, KR

The effect of a nano-sized silica particle on the surface insulation resistivity of non-oriented electrical steel sheet was investigated. Several kinds of nano-sized colloidal silica were mixed to the chromium-free coating solution, which is consisted [...]

Novel Metal Oxide Deposition Method to Fabricate Nanostructures

Mansouri M.R., Mansouri R., Sandooghchian M., Mansouri M.R., Mansouri R., Kerman Semiconductor Company and university of Payem -e- Noor, IR

by this project deposition of metal oxide like SnO2 was deposited on Si wafer by applying novel developed method and then ZnO pudgy nanopillars were fabricated on the very deposited layer. this new developed approach [...]
