Atomic volumes and volume functions for Ag−Cu alloys

Science in China Series E: Technological Sciences, 1998
Nine functions of atomic volume interaction have been established. The values of average atomic volumes and lattice constants of Ag−Cu alloys obtained from each V-function are, respectively, equal to each other and in good agreement with experimental values.

High volume ultrasonic liquid atomizer

The Journal of the Acoustical Society of America, 1987
An ultrasonic liquid atomizer particularly for high volume flow rates is disclosed. An enlarged tip with a plurality of orifices is provided to increase the flow rate. A gradual transition to the enlarged atomizer tip is provided to enhance performance.

Atomic volumes of transition metals

Solid State Communications, 1977
Abstract We discuss the various repulsive terms which can give rise to a minimum in the energy as a function of interatomic distances and permits the calculation of atomic volumes of transitional metal. We show that the direct overlap between atomic functions provides in a very simple way the repulsive contribution to the energy and must be included ...

The Atomic Volume of Isotopes

Nature, 1921
AT the discussion on isotopes at the Royal Society on March 3 the question was raised as to within what limits of accuracy the conclusion is justified that the atomic volume of the various isotopes of lead is constant, and the following collected results may therefore be of interest. There are two sets of data.

Atomic wall recombination and volume negative ion production

Review of Scientific Instruments, 2006
The development of a numerical code for the modeling of negative ion sources requires the knowledge of a lot of processes occurring both in the gas phase and at the surface. The present work concerns the effect of surface processes (in particular atomic wall recombination) on the kinetics of production/destruction of negative ions.

Atomic volumes and polarizabilities in density-functional theory

The Journal of Chemical Physics, 2012
Becke and Johnson introduced an ad hoc definition of atomic volume [J. Chem. Phys. 124, 014204 (2006)] in order to obtain atom-in-molecule polarizabilities from free-atom polarizabilities in their nonempirical exchange-hole dipole moment model of dispersion interactions.

Effective atom volumes for implicit solvent models: comparison between Voronoi volumes and minimum fluctuation volumes

Journal of Computational Chemistry, 2001
AbstractAn essential element of implicit solvent models, such as the generalized Born method, is a knowledge of the volume associated with the individual atoms of the solute. Two approaches for determining atomic volumes for the generalized Born model are described; one is based on Voronoi polyhedra and the other, on minimizing the fluctuations in the ...

Atomic diameters, atomic volumes and solid solubility relations in alloys

Acta Metallurgica, 1966
Abstract The use of the concepts of favourable and unfavourable size factor in predicting solid solubilities in metallic systems is discussed. The original concept of Hume-Rothery, Mabbott and Channel-Evans involved the use of atomic diameters which were defined as the closest distances of approach of atoms in the crystals of the elements.

Theoretical atomic volumes of the light actinides

Physical Review B, 2000
The zero-pressure zero-temperature equilibrium volumes and bulk moduli are calculated for the light actinides Th through Pu using two independent all-electron, full-potential, electronic-structure methods: the full-potential linear augmented-plane-wave method and the linear combinations of Gaussian-type orbitals-fitting function method.
