Naturally, the study of non-equilibrium properties involves different criteria although the equilibrium state and evolution towards the equilibrium state may be important. [Pg.316]

The difference between equilibrium and non-equilibrium systems exists in the time-dependence of the latter. An example of a non-equilibrium property is the rate at which a system absorbs energy when stirred by an external influence. If the stirring is done monochromatically over a range of frequencies an absorption spectrum is generated. Another example of a non-equilibrium property is the relaxation rate by which a system reaches equilibrium from a prepared non-equilibrium state. [Pg.485]

In conclusion, it appears that the majority of the most modem force fields do well in predicting structural and dynamical properties within wells on their respective PESs. However, their performance for non-equilibrium properties, such as timescales for conformational interconversion, protein folding, etc., have not yet been fully validated. With the increasing speed of both computational hardware and dynamics algorithms, it should be possible to address this question in the near future. [Pg.99]

As was the case for solubility, apparent viscosity of concentrated soy protein slurries is a non-equilibrium property that is highly sensitive to past history of the slurry and to the techniques of its measurement. [Pg.102]

As functional properties of soy proteins, viscosity and solubility are alike in that they are non-equilibrium properties of the system. In the case of solubility, there is at least evidence of steady state equilibrium which allows for the possibility of some qualitative thermodynamic interpretation. In the case of viscosity, steady state equilibrium is not reached. Thus, thermodynamic interpretation is impossible. Molecular dynamics data are needed. [Pg.108]

Because solubility and viscosity are non-equilibrium properties, the measured values are dependent upon measurement conditions, sample preparation, and past sample history. Because of this, it is difficult or sometimes even impossible to compare data, to generalize the data and make predictions, and to interpret the data in terms of the basic molecular forces. [Pg.108]

Grain boundaries (and boundaries between phases) are elements of the microstructure of crystalline solids, being characterized by their number, shape, and topological arrangement. The microstructure is a non-equilibrium property. In the next section we discuss grain boundaries. [Pg.50]

The focus of this chapter is exploration of the ability of mixed quantum classical approaches to capture the effects of interference and coherence in the approximate dynamics used in these different mixed quantum classical methods. As outlined below, the expectation values of computed observables are fundamentally non-equilibrium properties that are not expressible as equilibrium time correlation functions. Thus, the chapter explores the relationship between the approximations to the quantum dynamics made in these different approaches that attempt to capture quantum coherence. [Pg.417]

Now cellular automata technique is widely used in various applications. Rather complete reviews including common non-equilibrium properties of the dynamic processes are given in Refs. [233-235],... [Pg.429]

The Gaussian subchain model and its possible generalisations allows one to calculate, in a coarse-grained approximation, the different characteristics of a macromolecule and systems of macromolecules, playing a fundamental role in the theory of equilibrium and non-equilibrium properties of polymers. The model does not describe the local structure of the macromolecule in detail, but describes correctly the properties on a large-length scale. [Pg.6]

In a case of a general transformation, relations (1.16) and (1.17) are not valid and ought to be replaced by other relations. A non-orthonormal transformation matrix was used at investigation of non-equilibrium properties of the macromolecule in a liquid when so-called hydrodynamic interaction was taking into account (Zimm 1956). [Pg.7]

The non-equilibrium properties of PTC elements can also be utilized. If the room temperature resistance is low there will be a high current surge when a voltage is applied and this will fall to 1% or less of its initial value when the element heats up above its Curie point. Such devices are used in demagnetizing ( degaussing ) coils in T.Y. monitors and in place of capacitors in motor starters. [Pg.172]

Small disagreement may be due to some specific non-equilibrium properties of the supersonic expansion. [Pg.114]

Treatment of non-equilibrium properties of foam films requires consideration of the kinetics of expansion of a black spot in the grey film [102] as well as the formation of stratified black foam films (see Section 3.4). [Pg.122]

The intrinsic barrier therefore denotes the portion of the additional free energy possessed by the transition state with respect to the free energies of the adjacent ground (precursor and successor) states that arises only as a consequence of the non-equilibrium properties of the former. The elucidation of intrinsic barriers, at least relative values for a series of structurally related reactions or for different surface environments, is clearly of central fundamental importance in electrochemical kinetics. Although not often perceived in such terms, a major objective is therefore the utilization of strategies that correct, or otherwise allow for, the influence of thermodynamic contributions upon the experimental kinetic parameters. [Pg.34]

The polymer heat capacity data bank is, as outlined in the Introduction, is only the first step towards the establishment of a comprehensive Thermal Properties Data Bank. Presently we are expanding our efforts to include glass transition temperatures, melting temperatures and heats of fusion. In the planning stage are specific volune, compressibility, and thermal conductivity data banks, as well as the expansion to non-equilibrium properties. [Pg.361]

As can be seen from the above development, study of the transport properties of electrolyte solutions led scientists in the late nineteenth and early twentieth centuries to think about these systems on a microscopic scale. Important cormec-tions between the movement of ions under the influence of thermal and electrical effects were made by Einstein. This was all brought together in an elegant way by Onsager. An important question faced by those involved with these studies is whether the electrolyte is completely dissociated or not. The answer to this question can be found be examining both the equilibrium and non-equilibrium properties of electrolyte solutions. The latter aspect turns out to be more revealing and is discussed in more detail in the following section. [Pg.283]

The first section of this book covers liquids and. solutions at equilibrium. I he subjects discussed Include the thcrmodvnamics of solutions, the structure of liquids, electrolyte solutions, polar solvents, and the spectroscopy of solvation. The next section deals with non-equilibrium properties of solutions and the kinetics of reactions in solutions. In the final section emphasis is placed on fast reactions in solution and femtochemistry. The final three chapters involve important aspects of solutions at interfaces. Fhese include liquids and solutions at interfaces, electrochemical equilibria, and the electrical double layer. Author W. Ronald Fawcett offers sample problems at the end of every chapter. The book contains introductions to thermodynamics, statistical thermodynamics, and chemical kinetics, and the material is arranged in such a way that It may be presented at different levels. Liquids, Solutions, and Interfaces is suitable for senior undergr.iduates and graduate students and will be of interest to analytical chemists, physical chemists, biochemists, and chemical environmental engineers. [Pg.622]

The Debye-Hiickel theory discusses equilibrium properties of electrolyte solutions and allows the calculation of an activity coefficient for an individual ion, or equivalently, the mean activity coefficient of the electrolyte. Fundamental concepts of the Debye-Hiickel theory also form the basis of modern theories describing the non-equilibrium properties of electrolyte solutions such as diffusion and conductance. The Debye-Huckel theory is thus central to all theoretical approaches to electrolyte solutions. [Pg.349]

In order to understand the factors controlling plumbing and pumping, it is very important to explore the detailed molecular properties of proton wires in membrane proteins. In particular, it is essential to determine the subtle interplay between structural, equilibrium, and non-equilibrium properties in the molecular mechanism of proton transport in complex hydrogen-bonded networks. [Pg.164]
