PVT measurements, virial coefficients, and Joule-Thomson inversion curve of fluorine

, 1970
Experimental PVT measurements on gaseous and liquid fluorine from the triple point (53.5 K) to 300 K at pressures to about 21 MN/m2 are presented. The data are represented by a truncated virial equation in the low-density region.

Theoretical calculations for the superheated steam properties up to 8.0 MPa based on the ideal gas law with the compressibility factor Z

Case Studies in Thermal Engineering
Not only is superheated steam still widely used as a primary working fluid for driving various types of power generation systems, but it is also an essential intermediary substance for reforming fossil fuels.

Chiral liquid-crystalline polyacrylates from (S)-(-)-2-methyl-1-butanol. Synthesis, mesomorphic properties and light scattering

Journal of the Brazilian Chemical Society, 2001
The synthesis and mesomorphic behavior of two chiral side chain liquid crystalline polyacrylates from (S)-(-)-2-methyl-1-butanol are described. These new polyacrylates show a dependence of the phase transition temperatures on both, molecular weight and ...

Second virial coefficient in one dimension as a function of asymptotic quantities

, 2005
PTHA result from Dodd and Gibbs (J. Math. Phys., 15, 41 (1974)) for the second virial coefficient of particles in one dimension, subject to delta-function interactions, has been obtained by direct integration of the wave functions.
