We study the interaction of a liquid drop with an elastic beam in the case where bending effects dominate. We use a variational approach to derive equilibrium equations for the system in the presence of gravity and in the presence or absence of contact line pinning. We show that the derived equilibrium equations for the beam subsystem reveal the external forces applied on the beam by the liquid...

A mathematical model for the computation of the phase equilibrium and gas-particle partitioning in atmospheric organic aerosols is presented. The thermodynamic equilibrium is determined by the global minimum of the Gibbs free energy under equality and inequality constraints for a system that involves one gas phase and many liquid phases. A primal-dual interior-point algorithm is presented for t...

We study the effects of nuclear polarization M on the liquid-gas equilibrium phase diagram of 3He, in situations where the saturating vapour pressure increases or decreases as a function of M, and where a metamagnetic instability may occur in the liquid phase. Numerical predictions are given within the frame of a phenomenological model with parameters fitted to reproduce accurately the saturati...

In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...

Coulomb cluster of dust particles in an RF helium plasma under cryogenic environment is observed experimentally. Background neutral temperature is controlled by cryogenic liquid such as liquid helium or liquid nitrogen. Dust dynamics in a sheath is studied. A dust injected into a sheath moves toward an equilibrium position where the sheath electric force balances with the gravitational force. D...

Theoretical calculations are presented of solid-liquid equilibrium for linear quadrupolar molecules, focusing especially on the ratio of the triple point temperature to the critical temperature. The proposed treatment uses the hard quadrupolar dumbbell model as the reference system, and incorporates the effect of dispersion forces through a mean-field term. The reference system of quadrt/polar ...

Living systems are the most important and most complex of nonequilibrium liquid crystalline systems. We check an experimental minimal model for macroscopic implications of this statement. To do this, we consider “living systems” in terms of three broken symmetries: 1. liquid crystalline (broken continuous symmetry); 2. chiral (broken mirror symmetry) and 3. non-equilibrium (broken time reversal...
