Modeling of the self-propagating reactions of nickel and aluminum multilayered foils
(2009)
In this study, we performed simulations of self-propagating reactions of nanoscale nickel-aluminum multilayers using numerical methods. The model employs two-dimensional heat transfer equations coupled with heat generation ...
Efficient treatment of complex geometries for large eddy simulations of turbulent flows
(2004)
Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...
Recent advances in spintronics. Half-metal ferromagnets: Their role in spintronics
(2004)
A review of recent advances in spintronics is presented. We report the structural, magnetic, electrical and thermal properties of the ferromagnetic half-Heusler alloy NiMnSb grown by arcmelting. The bulk material is used ...
Disorder-induced vortex phase transition in untwinned YBa2Cu3O7-δ crystal
(2000)
Local magnetic measurements in an untwinned YBa2Cu3O7-δ crystal as a function of temperature, field and time reveal anomalies occurring along the same line BSS(T) in the field-temperature plane. We identify BSS(T) as a ...
Negative giant longitudinal magnetoresistance in NiMnSb InSb: Interface effect
(2006)
We report on the electrical and magnetotransport properties of the contact formed between n -type degenerate InSb (100) substrates and polycrystalline NiMnSb thin films grown using pulsed laser deposition. Negative giant ...
Investigation of Different Si(111) Surface Preparation Methods for the Heteroepitaxy of GaN by Plasma-Assisted MBE
(2001)
The in-situ low temperature preparation of hydrogen passivated Si(111) surfaces has been investigated for GaN growth by rf-plasma source molecular beam epitaxy. The GaN/Si heterostructures were analyzed by transmission ...
Synthesis and characterization of well-defined block and statistical copolymers based on lauryl methacrylate and 2-(acetoacetoxy)ethyl methacrylate using RAFT-controlled radical polymerization
(2008)
Four well-defined diblock copolymers and one statistical copolymer based on lauryl methacrylate (LauMA) and 2-(acetoacetoxy)ethyl methacrylate (AEMA) were prepared using reversible addition-fragmentation chain transfer ...
A modular modeling approach for the design of reconfigurable machine tools

A new generation of machine tools called Reconfigurable Machine Tools (RMTs) is emerging as a means for industry to be more competitive in a market that experiences frequent changes in demand. New methodologies and tools ...
Possible use of the half-Hausler alloy NiMnSb in spintronics: Synthesis and physical properties of arc melted NiMnSb and of NiMnSb thin films grown on InSb by pulsed laser deposition
(2005)
We report the growth of single-phase, stoichiometric polycrystalline thin films of the half-Heusler ferromagnet NiMnSb, predicted to be half-metallic, on single crystal (100) InSb substrates heated at 200 °C by pulsed laser ...
