Comparative study between computational and experimental results for binary rarefied gas flows through long microchannels
(2010)A comparative study between computational and experimental results for pressure-driven binary gas flows through long microchannels is performed. The theoretical formulation is based on the McCormack kinetic model and the ... -
Comparison of three resistor network division circuits for the readout of 4 x 4 pixel SiPM arrays
(2013)The purpose of this study is to investigate the behavior of a flexible SensL's silicon photomultiplier array (SPMArray4) photodetector for possible applications in PET imaging. We have designed and evaluated three different ... -
Diagnostics of the ions produced by laser ablation of TiC and TIB2
(1998)The composition and the kinetics of the plume produced during the pulsed laser deposition of TiC and TiB2 coatings on metal substrates was studied under film growth conditions. Mass analysis of ions of the ejected material ... -
A novel experimental setup for gas microflows
(2010)A new experimental setup for flow rate measurement of gases through microsystems is presented. Its principle is based on two complementary techniques, called droplet tracking method and constant-volume method. Experimental ... -
A quasi-continuum multi-scale theory for self-diffusion and fluid ordering in nanochannel flows
(2014)We present a quasi-continuum self-diffusion theory that can capture the ordering effects and the density variations that are predicted by non-equilibrium molecular dynamics (NEMD) in nanochannel flows. A number of properties ... -
Rarefied gas flow of binary mixtures through long channels with triangular and trapezoidal cross sections
(2010)The flow of binary gas mixtures through long micro-channels with triangular and trapezoidal cross sections is investigated in the whole range of the Knudsen number. The flow is driven by pressure and concentration gradients. ... -
Structure and dynamics of NiO(001) and Ni/NiO(001) surfaces by molecular dynamics simulation
(2000)Using molecular dynamics and a rigid ion potential, we studied the vibrational and structural properties of the NiO(001) surface with and without cationic adatoms. We found that the bulk phonon density of states (DOS) is ... -
Surface wettability effects on flow in rough wall nanochannels
(2012)The effect of rough-wall/fluid interaction on flow in nanochannels is investigated by NEMD. Hydrophobic and hydrophilic surfaces are studied for walls with nearly atomic-size rectangular protrusions and cavities. Our NEMD ...
