Welcome to Nanotech Germany, Research in Germany – Land of Ideas

Sicking F., Nanotech Germany, DE

Key technologies are “tickets” to the future. Nanotechnology is one of the most important key technologies. Nearly all branches of industry profit from the progress being made in nanotechnology research. And still, nanotechnology has a [...]

Preparation and Characterization of Bi-2212 thin films using pulsed laser depostion technique

Mua N.T., Rao C.N.R., Sundaresan A., Hien T.D., Man N.K., Hanoi University of Technology, VN

The surface morphology, microstructure and transport properties of the thin films are clearly a function of deposition temperature and post-annealing conditions.It is seen from our experimental data that post- annealing is required to obtain a [...]

Nanostructured films of novel azocompounds

Valdez-Hernandez Y.A., Rivera E., Carreon-Castro M.P., UNAM-Instituto de Ciencias Nucleares, MX

Thin nanostructured films by Langmuir and Langmuir-Blodgett technique of novel azocompounds are reported. Brewster’s angle microscopy (BAM), UV-Visible absorption and atomic force microscopy (AFM) were obtained to determine the stability and quality of the films. [...]

Nanostructure LB films of novel OPV compounds

Jimenez-Nava B., Alvarez-Venicio V., Carreon-Castro M.P., Nuclear Science Institute, MX

We studied the formation of Langmuir monolayers of two series of amphiphilic monodendrons -conjugated from first to third generation number with different length of terminal chains C3H7 and C12H25, the characterization of the monolayer was [...]

A Study about Surface Chemical-Physics Mechanisms Occurring for Interacting Metal Nanostructures / gas NO2

di Stasio S., Dal Santo V., National Research Council of Italy (CNR), IT

Zinc nanostructures synthesized with different morphologies from the same evaporation/condensation technique are studied with concern to surface reactivity to NO2 by Diffuse Reflectance Infrared Fourier Transformed Spectroscopy (DRIFTS). Synthesis of nanopowders is obtained, according to [...]

Maintaining Clean Surfaces in Cryogenic Measurement Environments

Lindemuth J., Lake Shore Cryogenics, US

Surfaces of nanoscale materials of all types must be kept clean to properly characterize their behavior. Materials that are characterized at cryogenic temperatures and in vacuum present additional challenges to maintaining clean surfaces. Any residual [...]

Effect of thermal treatments on the structure of photoactive titanium oxides

Diamanti M.V., Codeluppi S., Cordioli A., Pedeferri MP., Politecnico di Milano, IT

Nanocrystalline TiO2 is one of the most important and used photocatalysts because of the excellent efficiencies of conversion of chemical species, and its chemical stability. Its photocatalytic properties are activated only by UV light; nevertheless, [...]

Effects of the Shape of Nanoparticles on the Crystallization Behavior of Poly(ethylene terephthalate) Nanocomposites in the Flow Fields

Kim B.C., Jang K.H., Hahm W.G., Kikutani T., Lee J., Hanyang University, KR

This paper investigated the effects of the shape of nanoparticles on the crystallization behavior of high molecular weight poly(ethylene terephthalate) (PET ; inherent viscosity of 0.98 g/dl) in the shear and elongational flow fields. Two [...]

Deposition and Characterization of Platinum Nanoparticles on Highly Orientated Pyrolytic Graphite

Elizondo-Villarreal N., Novar C., Zhou J.P., Alvarez Contreras L., Tel Vered R., Universidad Autonoma de Nuevo Leon, MX

Platinum is considered one of the best electrocatalyst for low temperature reactions in a H2/O2 fuel cell. Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying [...]
