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

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 [...]

Synthesis and Characterization of ZnO Nanorods using Molecular Beam Epitaxy

Asghar M., Ali A., Hasan M.-A., Yasin Akhtar Raja M., Islamia University of Bahawalpur, PK

ZnO nanorods stand out as one of the most important candidates for next generation opto- and nano electronics. Synthesis of high quality and stable ZnO nanorods remains a challenge thus far. Similarly fabrication of thermally [...]

Magnetic properties of Sputter deposited and magnetically annealed IrMn/CoFeB nanometric bilayers for exchange biased magnetic tunnel junctions

Fulara H., Raju M., Chaudhary S., Kashyap S.C., Pandya D.K., Inidan Institute of Technology Delhi, IN

The work relates to the exploring the means of controlling the coercivities of the ferromagnetic thin films in a Magnetic Tunnel Junction Stack. Exchange bias route is a very powerful route in achieving this task. [...]

Theoretical Studies in Epitaxial Stabilization of ZnO-based Light-emitting Semiconductors

Liu P-L, Siao Y-J, Lee M.H., National Chung Hsing University, TW

The device quality ZnO films are expected to next generation materials applied in the field of photo-electronic devices. We find that (0001)-oriented ZnO, Zn0.875Be0.125O, Zn0.875Mg0.125O, and Zn0.875Al0.125O strained layer lattices soften as lattice parameter of [...]

High density InN/GaN nanodots were successfully grown by pulsed mode (PM) metal organic chemical vapor deposition (MOCVD). InN nanodots density of up to ~5×1010 cm-2 at a growth temperature of 550 ℃ was achieved The [...]

Characterization of an electrical powering nano-generator based on aluminum doped ZnO thin films

Muñoz Aguirre N., Rivera López J.E., Martínez Pérez L., Tamayo Meza P., Instituto Politecnico Nacional, MX

Conductive Atomic Force Microscopy (c-AFM) [1][2] characterization was made on Aluminum doped ZnO thin films. Furthermore, to the electrical resistance associated to the surface of the film, was in series connected a load resistance as [...]

Volume Grain Analysis in Organic Thin Film Semiconductors

Bergman D., Gentry K.P., Gredig T., California State University Long Beach, US

The grain structure of organic thin films is quantitatively studied and includes the precise grain area and volume distributions. The grain morphology affects the device performance of gas sensors and organic solar cells due to [...]

The Effects of POSS on the Interlaminar Shear Strength of Marine Composites under Various Environmental Conditions

Mahfuz H., Powell F., Granata R., Hosur M., Florida Atlantic University, US

The fiber/matrix (F/M) interface of carbon/vinyl ester composites has been modified by treating the carbon fiber with polyhedral oligomeric silsesquioxane (POSS). The objective was to improve the durability of the F/M interface in various environments. [...]
