Introduction Thermodynamic non-ideality can lead to serious problems in terms of the analysis of macromolecular behaviour in solution, particularly in molar mass and mass action measurements based on the principles of thermodynamic equilibrium. The term ‘molar mass’ (in g/mol) favoured by the physical chemist is of course equivalent to the molecular mass in daltons, and by ‘mass action’ we mean...

Relativistic plasma with radiation at thermodynamic equilibrium is a general system of interest in astrophysics and high energy physics. We develop a new selfconsistent quasi-particle model for such a system to take account of collective behaviour of plasma and thermodynamic properties are derived. It is applied to electrodynamic plasma and quark gluon plasma and compared with existing results....

The formal consideration of the concept of interaction in thermodynamic analysis makes it possible to deduce, in the broadest terms, new results related to the coevolution of interacting systems, irrespective of their distance from thermodynamic equilibrium. In this paper I prove the existence of privileged coevolution trajectories characterized by the minimum joint production of internal entro...

The occurrence of contaminants in wastewaters, and their behavior during wastewater treatment and production of drinking water are key issues to re-use water resources. The present research aims to remove caffeine from aqueous solutions via adsorption technique, using Multi-Wall Carbon Nanotubes (MWCNTs) as an adsorbent under different experimental conditions. The processing variables such as p...

Thermodynamic equilibrium in multicomponent solids subject to mechanical stresses is a complex nonlinear problem whose exact solution requires extensive computations. A few decades ago, Larché and Cahn proposed a linearized solution of the mechanochemical equilibrium problem by introducing the concept of open system elastic coefficients [Acta Metall. 21, 1051 (1973)]. Using the Ni-Al solid solu...

thermodynamic restrictions and simultaneous effects of operational conditions on the homogeneous rhodium-catalyzed carbonylation of methanol are studied in this line of research. it is shown that the general nrtl-virial model can be appropriated to study thermodynamics of the carbonylation. it is obtained that the reaction is kinetically and thermodynamically reasonable at temperatures above 42...

we assume that every act of absorption from lower level A to upper level B is followed by an act of emission from B to A. In other words, the number of atoms in state B is defined by the number in A, and by the transition probability A---B. This is in contradiction to the assumption of thermodynamic equilibrium. Since in thermodynamic equilibrium the number of atoms in any state is fixed, it se...

We use extensive computer simulations to probe local thermodynamic equilibrium (LTE) in a quintessential model fluid, the two-dimensional hard-disks system. We show that macroscopic LTE is a property much stronger than previously anticipated, even in the presence of important finite-size effects, revealing a remarkable bulk-boundary decoupling phenomenon in fluids out of equilibrium. This allow...
