Coherent quasiparticle transport in grain boundary junctions employing high-Tc superconductors

Tafuri F. et al. (2006)

mesoscopic physics, nanodevices, high critical temperature superconductorsMagneto-fluctuations of the normal resistance RN have been reproducibly observed in YBa2Cu3O7-ä biepitaxial grain boundary junctions at low temperatures. We attribute them to mesoscopic transport in narrow channels across the ...

To study the effects of degradation of phonon distribution on the high frequency response in nano structures

Sarkar S.-K et al. (2006)

low dimensional semiconductor nano structures, Frolich coupling, LO phonons , phonon lifetimeThere has been an intense interest in low dimensional semiconductor nano structures, because of subtle and profound changes that occurs, as length scale becomes comparable to the exciton Bohr radii and the ...

Experimental Investigation on the Bi-directional Growing Mechanism of the Foils Laminate Approach in AAO Fabrication

Fan J.-Y. et al. (2006)

anodic aluminum oxide, foils laminate approach, leakage blocking, triplex foils laminateThe foils laminate approach can be implemented to grow bi-directional porous pattern from both the top and bottom surfaces of an aluminum foil. It was intuitively inferred that leakage of the etchant between the ...

Effects of Ox-LDL on Macrophages NAD(P)H Autofluorescence Changes by Two-photon Microscopy

Lin, Ching-Ting et al. (2006)

Ox-LDL uptakes by macrophage play a critical role in the happening of atherosclerosis. Because of its low damage on observed cells and better signal-to- background ratio, two-photon excitation fluorescence microscopy is used to observe NAD(P)H autofluorescence of macrophage under difference cultured ...

CoFe2O4 NANOSTRUCTURED MAGNETIC MATERIALS: INFLUENCE OF NOT-CONVENTIONAL METHODS OF COMPACTION (SPS, HIP) ON THE MICROSTRUCTURE AND PHYSICAL CHARACTERISTICS.

Schoenstein, F. et al. (2007)

This work presents a Bottom-Up strategy implementing methods of soft chemistry followed by processes of not conventional compaction for making of CoFe2O4 spinel nanostructured materials. The optimization of the process routes to obtain bulk and dense materials will be described in details along with ...

Building CAD Prototyping Tool for Emerging Nanoscale Fabrics

Dezan, Catherine et al. (2007)

The design of CAD tools for nanofabrics involves new challenges not encountered with conventional CMOS technology. In this paper, we describe the design of a prototyping CAD tool targeting design automation of applications on a wide range of nanofabrics. Our proposal is based on a variety of models ...

Cell Architecture for Nanoelectronic Design

Martorell F. et al. (2006)

Nanoarchitectures, fault-tolerance, defect-tolerance, noise-tolerance, averaging cellSeveral nanoelectronic devices have been already proved. However, no architecture which makes use of them provides a feasible opportunity to build medium/large systems. Nanoarchitecture proposals only solve a small ...

Modeling of Ion Diffusion Induced Current through a Nanochannel

Yang F.-C. et al. (2006)

Ion diffusion induced current, Nanochannel, Concentration gradientIn this article, a theoretical model that takes into consideration both the diffusion and electric osmosis fluxes to estimate the diffusion current through a nanochannel is proposed. Equivalent impedance of a nanochannel is modeled as ...
