Millimolar bulk concentrations of the surfactant cetyltrimethylammonium bromide (CTAB) induce spreading of alkanes, H(CH(2))(n)H (denoted C(n)) 12< or =n< or =21, on the water surface, which is not otherwise wet by these alkanes. The novel Langmuir-Gibbs film (LGF) formed is a liquidlike monolayer comprising both alkanes and CTAB tails. Upon cooling, an ordering transition occurs, yielding a he...

Fluctuations of the maximal particle energy of the quantum ideal gas and random partitions Abstract We investigate the limiting distribution of the fluctuations of the maximal summand in a random partition of a large integer with respect to a multiplicative statistics. We show that for a big family of Gibbs measures on partitions (so called generalized Bose–Einstein statistics) this distributio...

E M F measurements were performed on a chemical cell containing a silver and a nitrate electrode. The systems N a N 0 3 + A g N 0 3 , L i N 0 3 + A g N 0 3 , and pure A g N 0 3 were investigated in a temperature range of 240 ° C to 310 ° C and in the total concentration range permitted by the phase diagram. We f ound a linear dependence of the E M F on temperature. Six constants, characteristic...

A method is developed to consistently satisfy the Gibbs equilibrium conditions between the quark-gluon and hadronic phase although each phase has been formulated in separate grand canonical partition function containing three quark flavours. The sector in the space of thermodynamic variables where the transition takes place is restricted to a curve, according to the phase diagram of QCD. The co...

We report a numerical simulation for the phase diagram of a simple two-dimensional model, similar to the one proposed by Noro and Frenkel [J. Chem. Phys. 114, 2477 (2001)] for membrane proteins, but one that includes the role of the solvent. We first use Gibbs ensemble Monte Carlo simulations to determine the phase behavior of particles interacting via a square-well potential in two dimensions ...

The effects of the addition of three inorganic salts, namely, NaCl, Na(2)SO(4), and Na(3)PO(4), on the liquid-liquid (L-L) phase diagram of aqueous solutions containing the model ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate, [bmim][BF(4)], were investigated. All three inorganic salts trigger salting-out effects, leading to significant upward shifts of the L-L demixing temperatures...
