Rheological study constructs a non-equilibrium thermodynamic model of cement paste.

the thermodynamic of the known and very effective catalytic system, hydrogen peroxide (h2o2) and methyltrioxorhenium (mto) is studied in different solvents using uv-visible spectroscopic method. the thermodynamic parameters (δg, δh and δs) for two equilibrium reactions, mto + h2o2 ⇌ a + h2o and a + h2o2 ⇌ b.h2o (a, [mere(o)2(o2)]; b.h2o, [mere(oh2)(o)(o2)2]), are determined. the obtained free e...

We introduce a new mean field kinetic model for systems of rational agents interacting in a game-theoretical framework. This model is inspired from noncooperative anonymous games with a continuum of players and Mean-Field Games. The large time behavior of the system is given by a macroscopic closure with a Nash equilibrium serving as the local thermodynamic equilibrium. An application of the pr...

this paper discusses the biosorption of ni(ii) ions from aqueous solutions by bacillus sphaericus biomass. the biosorption process was affected by the solution ph, biomass concentration, contact time, temperature and initial ni(ii) concentration respectively. the sorption kinetics and equilibrium data were described well with the pseudo-second order kinetic model and the freundlich isotherm mod...

The present-day atmosphere is in a unique state far from thermodynamic equilibrium. This uniqueness is for instance reflected in the high concentration of molecular oxygen and the low relative humidity in the atmosphere. Given that the concentration of atmospheric oxygen has likely increased throughout Earth-system history, we can ask whether this trend can be generalized to a trend of Earth-sy...

At temperatures moderately below their glass transition temperature, the properties of many glass-forming materials can evolve slowly with time in a process known as physical aging whereby the thermodynamic, mechanical, and dynamic properties all drift towards their equilibrium values. In this work, we study the evolution of the thermodynamic and dynamic properties during physical aging for a m...

For the special case of nonlinear gravitational clustering from an initially Poisson distribution , the counts-in-cells distribution function is obtained from the excursion set, Press-Schechter multiplicity function. This Poisson Press-Schechter distribution function has the same form as the gravitational quasi-equilibrium counts-in-cells distribution function, predicted by the Saslaw-Hamilton ...

Synopsis : The transient network model of Green-Tobolsky [1946], Yamamoto [1956] and Tanaka-Edwards [1992] is formulated within the frame of thermodynamics of irreversible processes, using as a fundamental quantity the chemical potential associated to the connection of strands to the network and treating these connections as chemical-like reactions. All thermodynamic quantities are thus natural...
