We show how the variational principle for Gibbs States (which says that for the d{ dimensional cubic lattice, the set of translation invariant Gibbs States is the same as the set of translation invariant measures which maximize entropy minus energy and moreover that this quantity corresponds to the pressure) fails for nearest neighbor nite state statistical mechanical systems on the homogeneous...

The osmotic coefficient of aqueous solutions of cyclohexylsulfamic acid was determined by freezing point measurements up to the molality 0.65 mol kg-1. The osmotic coefficients were fitted to the Pitzer equation, and ion interaction parameters α1, β(0) and β(1) were evaluated. The mean ion activity coefficient of the solute was calculated, and the non-ideal behaviour of the system investigated ...

Since the pH is treated as an independent variable in biochemical thermodynamics, the Gibbs energy G does not provide the criterion for equilibrium, but the transformed Gibbs energy G’ does. The standard transformed Gibbs energy of formation DfG’ of a reactant (sum of species) can be calculated at the desired temperature, pH, and ionic strength if the standard Gibbs energies of formation DfG an...

The, submaximal, thermodynamic efficiency of aerobic microbial growth depends on whether no consumption / production of 02, or no carbon product other than biomass, is admitted into the assimilation equation. When the growth substrate has a low degree of reduction, the former efficiency approaches 22 % whilst the latter approaches 54 %. Expectations for maximal growth rate at optimum efficiency...

biological materials. recently. are the building blocks of several self-assembling peptide and protein systems.the main challenge in molecular self-assembly is to design molecular building blocks that can undergospontaneous organization. these cyche peptides were produced by an alternating fl'ell number of d- and laminoacids.which interact through non-covalent interactions co an array of selfas...

the modified nrtl (m-nrtl) model is used to represent the excess gibbs free energy of aqueous (alcohol + electrolyte) solutions. in this work, the m-nrtl model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. the proposed extension is a modified of ...

In this investigation, the influence of doping graphene with silicon in the adsorption of alanine amino acid was inspected computationally. For this purpose, the structures of pure graphene, silicon doped graphene, alanine and 10 derived products of the alanine reaction with pure and silicon doped nano-adsorbents were optimized geometrically. Afterwards, the values of adsorption energy, formati...

In this study, high energy energy derivatives of TEX with different carbon-containing fullerenes at different temperature conditions were studied using density functional theory. For this purpose, the materials were first geometric optimized, then the thermodynamic parameters were calculated for all of them. Then, the process of changing the energy-dependent parameters such as specific heat cap...

Gibbs random eld (GRF) models work well for synthesizing complex natural-looking image data with a small number of parameters; however, estimation methods for these parameters have a lot of problems. This paper addresses the analysis problem in a new way by examining the role of the temperature parameter of the Gibbs distribution. Studies of the model energy with respect to the temperature are ...

Anfinsen’s thermodynamic hypothesis is reviewed and misunderstandings are clarified. It really should be called the thermodynamic principle of protein folding. Energy landscape is really just the mathematical graph of the Gibbs free energy function ( ) X; , N G U E , a very high dimensional hyper surface. Without knowing it any picture of the Gibbs free energy landscape has no theoretical base,...
