Combined spatially resolved electron-energy loss spectroscopy (EELS) and high resolution near-edge X-ray absorption fine structure (NEXAFS) spectroscopy have been used to investigate the nitrogen doping of multi-walled carbon nanotubes (N-MWNT). EELS indicates that most of the tubes are nitrogen-doped. NEXAFS spectros…

Texture formation during sheet stamping and die forging of α titanium alloys is studied, and the effect of texture and the mechanism of plastic deformation on the strength of internal-pressure spherical vessels is considered. It is shown that, apart from texture, the anisotropy of the strength properties of the α allo…

Recently proposed circuit-level models of carbon nanotube transistor (CNT) for SPICE-like simulators suffer from numerical complexities as they rely on numerical evaluation of integrals or internal Newton-Raphson iterations to find solutions of non-linear dependencies or both. Recently an approach has been proposed wh…

The transfer of kinetic units (atoms or groups of atoms) in amorphous materials from one quasiequilibrium position to another quasi-equilibrium position is governed by the fluctuations of both the energy and the entropy of the system. In the glass transition range of liquids, the entropy mechanism plays a dominant rol…

For many years, partial discharge (PD) activity has been used in air-cooled generators as one of the important indicators of degradation mechanisms in stator winding insulation. Up to a certain level, these degradation processes are slow. Under normal operation, PD measurement and trending can generally indicate that…

In this paper, we present rewritable liquid crystal (LC) gratings based on azo dye-doped polyvinyl alcohol films. The mechanism of such rewritable characteristics is attributable to the irradiation of these films with a suitable linearly polarized light beam which reorients dyes and then aligns LCs. Two gratings, one…

When a polycrystal is in chemical equilibrium, the microstructure evolves as a result of grain growth under the capillary driving force arising from the interface curvature. As the growth rate of an individual grain is the product of the interface mobility and the driving force, the growth of the grain can be controll…

Magnetic shape memory alloys (MSMA) are relatively new active materials but at this time they are not actually very used as actuators despite a high strain and a small response time. This is probably due in part to a large hysteresis and a strong non-linear behaviour. In this paper, an original hybrid control is desig…
