We demonstrate theoretically and experimentally a new multiplexing method for volume holographic storage using a single reference beam that is composed of multiple plane waves or is a spherical wave. We multiplex the holograms by shifting the recording mat ...
Self-consistent minimum free-energy calculations of the structure and lattice dynamics of forsterite at high pressure (up to 30 GPa) and high temperature (up to 1850 K) have been performed using an approach based on the Born model of solids. In the free-en ...
In unsaturated soil mechanics testing, total volume change of the specimen is related to both water and air volume changes and cannot be measured with the same techniques as in conventional saturated soil mechanics. Over the years, several methods have bee ...
The partial molar volume, .hivin.V, and the partial sp. vol., .hivin.n, were estd. for more than 25 polyelectrolyte structures. The materials investigated by d. measurements in highly dild. aq. solns. (c < 10-2 monomol/L) included both synthetic polyelectr ...
The pipetting of small volumes, typically ranging between a few and one thousand microliters (μl), is widely used in many laboratories and essentially relies on air displacement to aspirate and dispense the liquid contained in a small plastic tip. While th ...
La manipulation et l’assemblage de microsystèmes (MEMS) nécessite des robots de haute précision qui doivent fonctionner dans des environnements propres. Beaucoup des systèmes actuels ont un volume important et occupent une grande surface au sol par rapport ...
Periclase (MgO) has been studied up to 16 GPa and temperatures in excess of 3000 K by X-ray diffraction in an energy-dispersive configuration at the DCI storage ring of LURE (Laboratoire pour l'Utilisation du Royonnement Electromagnetique, Orsay, France). ...
