Supersonic molecular beams constitute a very powerful technique in modern chemical physics. They offer several unique features such as a directed, collision-free flow of particles, very high luminosity, and an unsurpassed strong adiabatic cooling during the jet expansion. While it is generally recognized that their maximum flow velocity depends on the molecular weight and the temperature of the...

A calorimetric and vapor-pressure study of the behavior of 'He adsorbed on Grafoil III the temperature range 4 to 15 K is reported. These results have been combined with preexisting low-temperature heat-capacity data to form a complete thermodynamic description of the film, The Grafoil substrate evidently consists almost entlrely of basal-plane graphite, with only a small fraction of energetica...

Coulomb corrections to the equation of state of degenerate matter are usually described by Debye-Hückel theory; however, recent studies have considered modifications of thermodynamic quantities which are caused by the interactions of charged particles beyond the Debye-Hückel approximation. Based on the weakly-coupled plasma limit, the formulae for the physical properties of non-ideal effects on...

In high-pressure dynamic thermodynamic processes, the pressure is much higher than the air critical pressure, and the temperature can deviate significantly from the Boyle temperature. In such situations, the thermo-physical properties and pneumatic performance can’t be described accurately by the ideal gas law. This paper proposes an approach to evaluate the pneumatic performance of a high-pres...

LiF-UF 4 is a key binary system for molten fluoride reactor technology, which has not been scrutinized as thoroughly the closely related LiF-ThF system. The phase diagram equilibria in are explored this work with X-ray diffraction (XRD) and differential scanning calorimetry (DSC). short-range ordering salt solution moreover surveyed Extended Absorption Fine Structure spectroscopy (EXAFS) interp...
