Review of Double Wall Carbon Nanotubes, Synthesis and Applications (overview presentation)

Bacsa W., University of Toulouse, FR

We find that the Raman G band for individual double wall carbon nanotubes is split when the two walls are closely spaced or strongly coupled. We show that agglomeration of tubes into bundles leads to [...]

Interfacial Effect in Fe/ InGaAs Magnetism

Berrouachedi N., Rioual S., Lescop B., Rouvellou B., Langlois J., Bouslama M., Lounis Z., Abdellaoui A., ENSET d’Oran, DZ

The characterization of Ferromagnet / Semiconductor interfaces Fe/In0.5Ga0.5As system has been a topic of great interest because of the possible future development of spintronics, e.g., spin injection through the ferromagnetic thin film to the semiconductor. [...]

Nano Crystalline Cellulosic Nematic monocrystals optical properties

Picard G., Kadiri Y., Simon D., Ghozayel F., Lebreux J.-D., Ahuntsic College, CA

Magnificent opalescent effects are observed from the interaction between light and Nano Crystalline Cellulose (NCC). Leaving a thin liquid NCC suspension to slowly evaporate, a dry polycrystalline nematic cholesteric wafer was obtained. It was observed [...]

Evaluation of Uncertainty in Nanoparticle Size Measurement by Differential Mobility Analysis

Lin C-M, Yu T.-C., Lai S.H., Ho H.C., Weng H.F., Wang S-H., Chen C-J., Center for Measurement Standards, Industrial Technology Research Institute, TW

This paper presents the measurement results and the uncertainty analysis for four batches of polystyrene latex (PSL) spheres with nominal sizes of 20 nm, 100 nm, 300 nm and 500 nm using the measurement system [...]

Oxygen Vacancies induced ferromagnetism in undoped and Cr doped SnO2 nanowires

Zhang L., Ge S., Zuo Y., Jing Q., Lanzhou University, CN

Observations of room temperature ferromagnetism (FM) in various pristine oxides have been reported recently. The findings have urged researchers to explore the origin of FM, but there is no uniform model to explain this issue [...]

Application of nanoindentation for constituent phases testing

Hussainova I., Jasiuk I., Tallinn University of Technology, EE

Development of advanced composites requires a detailed knowledge of their constituents’ properties as they are often somewhat different from the materials at their bulk form. In the present study, the nanoindentation techniques of two different [...]

Laser-Induced Breakdown Spectroscopy (LIBS) for on-line monitoring and workplace surveillance of nanoparticle production processes

Frejafon E., CILAS, FR

Today, nanotechnology is a growing field of research and nanoparticle-based material production is expected to soar in years to come. The development of robust and reliable technologies for detection and measurement of airborne nanoparticles is [...]

Evaluation of Tools for Nanoparticles-modulated Hyperthermia by Atomic Force Microscopy

Reshetov I.V., Chissov V.I., Sukharev S.S., Matorin O.V., Korizky A.V., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

Some of the properties of the medicinal forms and tools, supposed to be used as hyperthermia modulators, can be evaluated by the atomic force microscopy (AFM): sizes and concentration of nanoparticles, their capability for the [...]

Novel Nanoparticles Dispersing Beads Mill with Ultra Small Beads and its Application

Inkyo M., Kotobuki Industries Co., Ltd., JP

We have developed the new type of beads mill and succeeded to solve the many problems for nanoparticles dispersion such as reaglomeration and the damage of crystal structure of nanoparticles. We use the centrifugation technology [...]
