چکیده

By finding that intramolecular properties and smearing dynamics of a solvation shell exhibit the anomalous order crossing Widom line, we demonstrated supercritical fluid is mixture liquid gas possessing heterogeneity.

The Widom line as the crossover between liquid-like and gas-like behaviour in supercritical fluids

According to textbook definitions1, there exists no physical observable able to distinguish a liquid from a gas beyond the critical point, and hence only a single fluid phase is defined. There are, however, some thermophysical quantities, having maxima that define a line emanating from the critical point, named ‘the Widom line’2 in the case of the constant-pressure specific heat. We determined ...

Molecular Hydrogens Dissolved in Liquid Crystals

The NMR spectra of molecular hydrogen isotopologs dissolved and orientationally ordered in nematic liquid-crystal solvents provide a wealth of information. Because they are quantum rotors, the various isotopologs H2, D2, T2, HD, HT, and DT have different order parameters, with larger internuclear distance having smaller order parameter. The signs and magnitudes of the order parameters are liqui...

Molecular Dynamics simulations of rod-like polyelectrolytes

We present theoretical and numerical results on stii, linear polyelec-trolytes within the framework of the cell model. With the help of an innec-tion point criterium we discuss counterion condensation for systems with added salt. Molecular dynamics simulations of the cell model are used to show, under which circumstances the mean-eld Poisson-Boltzmann theory fails qualitatively. We present meas...

Comparing molecular photofragmentation dynamics in the gas and liquid phases.

This article explores the extent to which insights gleaned from detailed studies of molecular photodissociations in the gas phase (i.e. under isolated molecule conditions) can inform our understanding of the corresponding photofragmentation processes in solution. Systems selected for comparison include a thiophenol (p-methylthiophenol), a thioanisole (p-methylthioanisole) and phenol, in vacuum ...

Diamond-Like Carbon film from Liquid Gas on Metallic Substrates

Liquid gas was used to produce DLC films on Cu, Al and steel substrates by DC plasma technique. The absorption in IR reflectance indicates, grown films are DLC. By deconvolution of room temperature UVvisible spectra of the films grown at 50 mtorr and 200C, in addition to the spectra lines reported for CL, PL, PLC and ESR, some new spectra lines were obtained. We also, have seen exciton absorpti...
