Abstract Microscopic expressions for the elastic constants of binary liquid crystalline mixtures composed of short rigid uniaxial molecules are derived in the thermodynamic limit at small distorsions and a small density. Uniaxial and biaxial nematic phases are considered. The expressions involve the one-particle distribution functions and the potential energy of two-body short-range interactions. The theory is used to calculate the phase diagram of a mixture of rigid prolate and oblate molecules. The concentration dependence of the order parameters and the elastic constants are obtained. The possibility of phase separation is not investigated.

Shock Wave Formation

This paper presents a study of two-particle inclusive angular correlations among "black" and "grey" particles produced in the interaction O16 nuclei with photoemulsions at 2.1 GeV/nucleon. The experimental data have been compared with the Monte Carlo simulated values assuming an independent emission. It has been observed that there is some short-range correlation among the target fragments, which may indicate shock-wave formation.

Comprehensive equations for the thermodynamic properties of aqueous NaI, CsF, CsCl, CsI, NaIO3, KIO3, CsIO3, KClO4, and HCl are generated by combining the heat capacity and density measurements reported by the first author with literature data for the enthalpy and Gibbs energy, or activity, as a function of molality at 298 K. The composition dependence is represented by the equations of Pitzer, which combine a theoretical form and Debye–Hückel terms with empirically evaluated parameters for short-range ion interactions. Temperature dependencies are represented by simple empirical equations, which should be reliable to 413 K or a little higher.

We present a 3D Ensemble Monte Carlo particle-based simulator with a novel realspace treatment of the short-range electron – electron and electron-ion interactions. By using a corrected Coulomb force in conjunction with a proper cutoff range, the shortrange portion of the force is properly accounted for, and the ‘double counting’ of the long-range interaction is eliminated. The proposed method naturally incorporates the multi-ion contributions, local distortions in the scattering potential due to the movement of the free charges, and carrier-density fluctuations. The doping dependence of the low-field mobility obtained from 3D resistor simulations closely follows experimental results, thus supporting the appropriateness of the proposed scheme. Simulations of ultra-small MOSFETs demonstrate that the short-range electron – electron and electronion interactions are responsible for the fast thermalization of the carriers at the drain end of the device, which occurs over distances that are on the order of few nanometers. The omission of the short-range portions of these two interaction terms leads to significant overestimation of the distance over which carriers thermalize.
