Self-propagating high temperature synthesis and dynamic compaction of titanium diboride/titanium carbide composites
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-05)
Self-propagating High-temperature Synthesis (SHS) of titanium and boron carbide (B 4 C) combined with explosively driven Dynamic Compaction (DC) was employed for the fabrication of composite TiB 2 /TiC compacts. A 2 3 ...
Excluded volume effects on the birefringence and stress of dilute polymer solutions in extensional flow
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-10)
An algorithm is derived for calculating flow-induced birefringence using a bead-spring model with and without excluded volume effects. The simulation results for the bead-spring model compare well with experimental results ...
Biomass evolution in porous media and its effects on permeability under starvation conditions
(John Wiley & Sons, Inc., 2000-07-05)
The purpose of this study was to understand bacteria profile modification and its applications in subsurface biological operations such as biobarrier formation, in situ bioremediation, and microbial-enhanced oil recovery. ...
Kinetic Separation of Oxygen and Argon Using Molecular Sieve Carbon
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
A pressure-swing adsorption (PSA) simulation study was performed for the separation of a mixture of 95% O 2 and 5% Ar using a molecular sieve carbon (MSC) as the adsorbent. Two PSA cycles have been outlined to maximize the ...
Dephasing of optically induced excitonic coherences in semiconductor heterostructures
(Springer-Verlag, 2000-11)
Resonant optical excitation of a direct bandgap semiconductor below the band edge induces excitonic coherences. Experiments based on transient four-wave mixing or cw spectral-hole burning provide an excellent approach to ...
Structural effects on adsorption of atmospheric gases in mixed Li,Ag– X -zeolite
(Wiley Subscription Services, Inc., A Wiley Company, 2000-11)
Silver is known to strongly affect the adsorptive properties of zeolites. In the synthesis of mixed Li,Ag low-silica X-type (LSX) zeolite, adding very small amounts of silver and specific dehydration conditions results in ...
Heat-transfer analysis of microfabricated thermocapillary pumping and reaction devices
(IOP Publishing Ltd, 2000-03-01)
A heat-transfer analysis was performed on thermocapillary pumping, a surface-tension-based drop pumping mechanism. The analysis, which incorporates both fluid flow and energy transport through multiple device layers, reveals ...
Similarity of Percolation Thresholds on the HCP and FCC Lattices
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-02)
Extensive Monte Carlo simulations were performed in order to determine the precise values of the critical thresholds for site ( p hcp c , S =0.199 255 5±0.000 001 0) and bond ( p hcp c , B =0.120 164 0±0.000 001 0) ...
Formation and aging of incipient thin film wax-oil gels
(Wiley Subscription Services, Inc., A Wiley Company, 2000-05)
A fundamental study of the deposition and aging of a thin incipient wax-oil gel that is formed during the flow of waxy oils in cooled pipes was performed. The solubility of high molecular weight paraffins in naphthenic, ...
