The nanostructure, wear and corrosion performance of arc-evaporated CrBxNy nanocomposite coatings
(2009)
The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS ...
Nanostructure, mechanical and tribological properties of reactive magnetron sputtered TiCx coatings
(2008)
This study describes the correlation between microstructure, mechanical and tribological properties of TiCx coatings (with x being in the range of 0–1.4), deposited by reactive magnetron sputtering from a Ti target in ...
Tribological properties of twin electron-beam evaporated Cr-N and Al-Cr-N coatings under laboratory sliding and drill experiments
(2008)
The tribological behavior of substoichiometric Cr-N and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was studied. Al-Cr-N coatings with Al to Cr ratios in the range of 1-8 (and nitrogen concentrations ...
Hall effect study of magnetoresistive perovskite LaNi0.5Co 0.5O3 thin films
(2004)
We report on the Hall effect of LaNi0.5Co0.5O 3 magnetoresistive thin films grown on Si(100) substrates by pulsed laser deposition. The Hall resistivity exhibits sign reversals both in varying magnetic field and temperature, ...
The density of water in carbon nanotubes
(2008)
In this paper, the density of water confined in carbon nanotubes of different sizes and chirality is calculated. Molecular dynamics is used to simulate the spontaneous filling of the nanotube with water molecules coming ...
Electronic structure of K 2Bi 8Se 13
(2005)
K 2Bi 8Se 13 belongs to a class of complex chalcogenides that shows potential for superior thermoelectric performance. This compound forms in two distinct phases, α and β. The β phase, which has several sites with mixed ...
Thickness dependence of Hall transport in Ni1.15Mn 0.85Sb thin films on silicon
(2004)
Highly spin polarized Heusler alloys, NiMnSb and Co2MnSi, attract a great deal of interest as potential spin injectors for spintronic applications. Spintronic devices require control of interfacial properties at the ...
Electronic Structure of K2Bi8Se13
(2002)
K 2Bi8 Se13 belongs to a class of complex Bi-Te-Se systems which show great potential for thermoelectric performance. This compound forms in two distinct phases α-K 2Bi8 Se13 (triclinic with space group P-1) and β-K 2Bi8 ...
LES of the flow past a rectangular cylinder using the immersed boundary concept
(2003)
Incompressible turbulent flow past a long square cylinder is investigated using large eddy simulations LES). Results are presented and compared with available experimental databases for a Reynolds number Red = 22 000. The ...
Minority-spin band parameters in a NiMnSb thin film determined by spectral conductivity
(2004)
NiMnSb is expected to be a ferromagnetic half metal, an expectation that is based in part on band structure calculations. Here we report optical conductivity studies of the band structure for a film prepared by pulsed laser ...
