Magnetic properties of ceramic composite using melt process

Lee S-H., Sunmoon University, KR

The critical transition temperature and critical current density of YBaCuO single crystal bulk were measured after heat diffusion treatment in nano powder. The superconducting start temperature was found to high at 91.62K. It can be [...]

Alignment of Different Functional Single Wall Carbon Nanotubes using Fe2O3 Nanoparticles under External Magnetic Field

Younes H., Hong H., South Dakota School of Mines and Technology, US

In this work we describe a new approach to align functionalized single walled carbon nanotubes (SWNTs) by γ-Fe2O3 in the presence of an external magnetic field without using chemical surfactant. Five different functionalized SWNTs are [...]

Self-assembled Magnetic Silica Nano-rods and Micro-platelets as smart reinforcements for polymer-composites

Furlan M., Lattuada M., University of Fribourg, CH

In this work, we propose a new versatile self-assembly technique to obtain large quantities of silica-based magnetic nano and micro-rods and of magnetic microplatelets, which can be easily oriented by weak magnetic fields. Our process [...]

Energy Spectrum of a Symmetric Graphene Double-Quantum-Dot System in a Normal Magnetic Field

Morgenstern Horing N.J., Liu S.Y., Silverman S., Raytheon Company, US

We examine the subband energy spectrum of a coupled symmetric Graphene double-quantum- dot system subject to Landau quantization in a normal magnetic eld. To formulate the dispersion relation, we construct the coupled double-dot Graphene Green`s [...]

Weak Magnetic Fields Sensing Using Soft Ferrite Nanoparticles and MEMS

Lyshevski S.E., Rochester Institute of Technology, US

We perform the feasibility analysis of sensing weak magnetic fields by using soft ferrite nanoparticles embedded in molecular complexes. The sensing mechanisms are based on the deflection of molecular complexes and induced strain due to [...]

Visual Motion Analysis of Nanoplatforms Flow under an External Magnetic Field

Nakhmani A., Etgar L., Tannenbaum A., Tannenbaum R., Lifshitz E., Tannenbaum A., Tannenbaum R., Technion – Israel Institute of Technology, IL

We use the tools of nanotechnology and develop a visual tracking algorithm for motion analysis of nanoplatforms under the influence of an external magnetic field. We have studied quantitative relationships between nanoplatform sizes, fluid flow [...]

Sensing Weak Magnetic Field By Leaving Biosystems and A Magnetoreseption Mechanism For Navigation

Lyshevski S.E., Rochester Institute of Technology, US

This paper examines and demonstrates a possible mechanism of sensing weak magnetic fields in biosystems.

Nanoparticle-enhanced Magnetic Field Induces Apoptosis in Nematode

Huang G.S., Yeh L.K., Chen Y-C, National Chiao Tung University, TW

To investigate molecular consequence of magnetic field to C. elegans, Fe3O4 nanoparticles were incorporated into the culture media of C. elegans and the nematodes were grown under magnetic field for 4 days. For the expermental [...]

Magnetically associated carbon nanotubes with mammalian cells: flow cytometry characterization and applications

Cai D., Blair D., Dufort F.J., Gumina M.R., Huang Z., Hong G., Kempa K., Ren Z.F., Chiles T.C., Boston College, US

Magnetic CNT can be driven into cells because it has an embedded Ni nanoparticle in its tip. We show herein that CNT-cell complexes are formed in the presence of a magnetic field. The complexes were [...]

Ways to Increase the Length of Single Wall Carbon Nanotubes in a Magnetically Enhanced Arc Discharge

Keidar M., Levchenko I., Shashurin A., Waas A.M., Ostrikov K., The George Washington University, US

It is demonstrated that the magnetic field has a profound effect on the length of a single wall carbon nanotube (SWNT) synthesized in the arc discharge. An average length of SWNT increases by a factor [...]
