Liquids realize a highly complex state of matter in which strong competing kinetic and interaction effects come to life. As such, liquids are more challenging understand than either gases or solids generally. In weakly interacting gases, the dominate. By contrast, low temperature typically feature far smaller fluctuations about their ground state. Notwithstanding complexity, with exception quan...

This study is devoted to the analysis of physical meaning difference in results viscosity measurements obtained by using two-capillary method—carrying on same flow rate through two circular parallel capillaries different lengths but diameter. Furthermore, there other approach for short determination a value, known as “elongational viscosity,” based concept domination extension at convergent alo...

Among the outstanding problems in the theory of supercooled liquids are the reasons for the rapid increase in their viscosity and relaxation times as the temperature is lowered towards the glass transition temperature T g , the non-exponential time dependence of the relaxation, and the possible connection between these two properties. The ferromagnetic Potts model on a square latice is a simple...

A vibrational model of heat transfer in simple liquids with soft pairwise interatomic interactions is discussed. general expression derived, which involves an averaging over the liquid collective mode excitation spectrum. The applied to quantify a dense Lennard-Jones and strongly coupled one-component plasma. Remarkable agreement available numerical results documented. similar picture does not ...

Mixtures of ionic liquids with organic solvents exhibit a most interesting research area in thermodynamics. The increasing utilization of ionic liquids in chemical processes and separation processes requires reliable and systematic data of thermodynamic and thermophysical properties such as activity coefficients, VLE and LLE data, heats of mixing as well as gas solubility data, densities and tr...

In this paper, doping liquid materials to enhance the electro-optical (EO) properties of twisted nematic liquid crystals (NLCs) was presented. Two aromatic hydrocarbon (AH) liquids, toluene and 1-methylnaphthalene, were chosen as dopants in order to lower the driving voltage and response time of the NLCs. A 18% decrease in driving voltage and response time was achieved by doping 10 wt% toluene ...

Most abso lut e meas urements of viscos ity have utili zed ca pi ll a ry fl ow, and required ~" 'TIl e mpir i ca l corrections amou nting to several times th eir precis ion and esti ma ted acc uracy .

We discuss the effect of zero-temperature attenuation, which has been recently observed in spin dynamics of spin-polarized Fermi liquids, on other Fermi-liquid processes. The transfer of" this attenuation mechanism J?om transverse spin dynamics to longitudinal processes can be caused by the magnetic dipole interaction, namely, by the direct dipole processes and the dipole coupling between the t...
