Effect of length and radius of singlewall carbon nanotube on its mechanical properties

Alzubi F.G., Cosby R., Kuwait Institute for Scientific Research, KW

A first principles atomistic calculations and analysis of Young’s modulus for short arm chair carbon nanotubes with different lengths and radii is]]are reported. The atomic forces and total energies were computed for the carbon nanotubes [...]

Dependence of electrical and thermal parameters of CNT bundles on their geometry

Jain N., Solid state physics lab, IN

Carbon nanotube bundles are being considered for VLSI interconnect applications due to their superior electrical and thermal properties. In this paper we report the variation in electrical and thermal conductance as well as inductance of [...]

Dielectrophoresis and Comsol Simulation of Cell Entrapment At Electrodes

Padmaraj D., Zagozdzon-Wosik W., Pande R., Miller J.H., Xie L-M, Wosik J., Zagozdzon-Wosik W., University of Houston, US

Dielectric properties of biological samples change with frequency of the interrogating electric field therefore can be used to obtain information about structures and various kinetic as well as bio-physical and –chemical processes in the cells. [...]

Conductance Enhancement of Nanoparticulate Indium Tin Oxide Layers Made by Printing Technique

Gross M., Maksimenko I., Faber H., Linse N., Wellmann P.J., University Erlangen-Nuremberg, DE

To improve their conductance we applied several treatments on nanoparticulate indium tin oxide (In2O3:Sn, ITO) layers: post bake, infiltration by an ITO precursor solution with subsequent sol-gel transformation into ITO, treatment with etching agents as [...]

Low-T Quantum Transport in Carbon Nanotubes: Role of Vacuum Fluctuations in Loss of Phase Coherence

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., ENEA, IT

Among the items in the design of new generation of electronic devices there are the measurement and understanding of the current-voltage response of an electronic circuit in which molecular systems like carbon nanotubes (CNTs) act [...]

Detection of Live Breast Cancer Cells Using Carbon Nanotube Devices

Teker K., Cesarone G., Wickstrom E., Panchapakesan B., Frostburg State University, US

Development of new technologies for reliable early detection of cancer from biological fluids via minimally invasive methods is still a high priority. Cancer cells often overexpress characteristic surface receptors, which provide an opportunity for early [...]

Conductance of a Disordered Double Quantum Wire in a Magnetic Field: Boundary roughness scattering

Arapan S.C., Korepov S.V., Liberman M.A., Johansson B., Uppsala University, SE

Boundary roughness scattering in disordered tunnel-coupled double quantum wires in the presence of a magnetic field is considered. The low-temperature conductance as a function of applied magnetic field is calculated for different structure and disorder [...]

Simulation Studies of Channels in Biological Membranes

Henderson D., Busath D.D., Rowley R.L., Crozier P.S., Boda D., Brigham Young University, US

The results of our recent studies of the selectivity of a calcium channel by means of a Monte Carlo simulation and of the conductance of ions in a model channel by means of a molecular [...]
