Show Abstract
The existing theoretical cross section data for the charge exchange process of multiply charged fully stripped ions with hydrogen atoms are evaluated in the energy range from ∼10 eV/u to ∼103 keV/u. The evaluation has been performed on the basis of both pure theoretical arguments and comparison with the most accurate experimental cross sections. The ionic charge state ranges from Z=2 to Z=54. The theoretical methods for calculation of the charge exchange cross sections are briefly discussed, and their regions of validity and the accuracy of the produced data are assessed.

Show Abstract
The existing theoretical cross section data for charge exchange of partially stripped ions on atomic hydrogen are evaluated in the energy range from ∼10 eV/u to ∼103 keV/u. The evaluation has been carried out by using both pure theoretical arguments and comparison with the most accurate experimental data. Ions with atomic numbers Z=3–8, 10, 12, 13, 14, 16, 18, 22, 26, 30, 36, 41, 42, 48, 54, 73, and 74, in charge states q between q=2 and q=(Z−1), have been examined. A brief discussion of the evaluation criteria is also given.

Show Abstract
Experimental and theoretical cross section data for electron impact ionization of light atoms and ions have been assessed. Based on this assessment and, in some cases, on the classical scaling laws, a recommended cross section has been produced for each species. This has been used to evaluate recommended Maxwellian rate coefficients over a wide range of temperatures. Convenient analytic expressions have been obtained for the recommended cross sections and rate coefficients. The data are presented in both graphical and tabular form and estimates of the reliability of the recommended data are given.

Show Abstract
Data for the viscosity and thermal conductivity coefficient of gaseous and liquid ethylene have been evaluated and represented by an empirical function, developed in previous work. Tables of values are presented for the range 110–500 K for pressures to 50 MPa (≊500 atm). Both the viscosity and thermal conductivity coefficients are estimated to have uncertainties of about ±5% increasing to 10% in the dense liquid. It is stressed that the data base could be improved. As in our work with other fluids, the anomalous contribution to the thermal conductivity in the vicinity of the critical point is included.

Show Abstract
Data for the viscosity and thermal conductivity of dense gaseous and liquid heavy water (D2O) have been reviewed and critically evaluated. Selected data were fitted to equations, from which tables of values were generated from temperatures up to 500 °C and for pressures up to 100 MPa for the viscosity and up to 550 °C and 100 MPa for the thermal conductivity. The uncertainties of the tabular values were estimated. The present paper is intended to explain the background of the International Representations of the Viscosity and Thermal Conductivity of Heavy Water Substance of the International Association for the Properties of Steam. With the aid of the present correlations, the kinematic viscosity, thermal diffusivity, and Prandtl number have been calculated. The present status of the gaseous diffusion coefficient is also briefly reviewed.

Show Abstract
Values for standard enthalpies of formation and dissociation energies for gaseous diatomic monoxides have been selected by critical assessment of experimental data from the literature. Gibbs energy functions, (−(G○T −H○298)/T), and enthalpy functions, (H○T −H○298), have been calculated from literature values for molecular parameters. Computer methods of storage, processing and retrieval are described and the resulting data are given in tables 4 to 11.

Show Abstract
The vapor pressure data on 324 coal compounds are collected and analyzed. The adopted data sets for each substance are weighted and combined to fit into a Cox vapor pressure equation, log10P=(1−D/T)×10(A+BT+CT2) by the least‐squares method. The results of the literature review and the evaluated values of coefficients for the vapor pressure equations are presented in separate tables. For ease of presentation, the coal compounds are divided into seven groups, based upon their molecular structures. They are (1) benzene and its derivatives, (2) naphthalene and its derivatives, (3) saturated ring compounds, (4) unsaturated ring compounds, (5) heterocyclic sulfur compounds, (6) heterocyclic nitrogen compounds, and (7) heterocyclic oxygen compounds.
