Opportunity theory

The physical picture in concentrated electrolytes is more apdy described by the theory of ionic association (18,19). It was pointed out that as the solutions become more concentrated, the opportunity to form ion pairs held by electrostatic attraction increases (18). This tendency increases for ions with smaller ionic radius and in the lower dielectric constant solvents used for lithium batteries. A significant amount of ion-pairing and triple-ion formation exists in the high concentration electrolytes used in batteries. The ions are solvated, causing solvent molecules to be highly oriented and polarized. In concentrated solutions the ions are close together and the attraction between them increases ion-pairing of the electrolyte. Solvation can tie up a considerable amount of solvent and increase the viscosity of concentrated solutions. [Pg.509]

Smeaton was a born mechanic and incessant experimeiitor, but a man of simple tastes and wants. He limited his professional engagements in order to devote a certain portion of his time to scientific investigations. One of Smeaton s rules was not to trust deductions drawn from theory when there was an opportunity for actual experiment. In 1771 Smeaton founded a club for engineers, which later came to be call the Smeatonian Society. ... [Pg.1050]

One possibility for this was demonstrated in Chapter 3. If impact theory is still valid in a moderately dense fluid where non-model stochastic perturbation theory has been already found applicable, then evidently the continuation of the theory to liquid densities is justified. This simplest opportunity of unified description of nitrogen isotropic Q-branch from rarefied gas to liquid is validated due to the small enough frequency scale of rotation-vibration interaction. The frequency scales corresponding to IR and anisotropic Raman spectra are much larger. So the common applicability region for perturbation and impact theories hardly exists. The analysis of numerous experimental data proves that in simple (non-associated) systems there are three different scenarios of linear rotator spectral transformation. The IR spectrum in rarefied gas is a P-R doublet with either resolved or unresolved rotational structure. In the process of condensation the following may happen. [Pg.224]

Having no opportunity to touch upon this topic, we refer the readers to the aforementioned chapters of the manograph The Theory oof Difference Schemes , in which the method of extraction of stationary nonhomogeneities was employed with further reference to a priori estimates of z. The forward difference scheme with cr = 1 converges uniformly with the rate 0 h + r) due to the maximum principle. [Pg.495]

Modularity. Since we would like to use the sufficient theory in a variety of contexts and problems, we need a theory that was easy to extend and modify depending on the context. In our state-space formulation the sufficient theory is couched in terms of constraints on variables. This theory gives us the opportunity to modularize its representation, partitioning the information necessary to prove the looseness of one type of constraint from that required to prove the looseness of a different constraint type. The ability to achieve modularity is a function not only of the theory but also of the representation, which should have sufficient granularity to support the natural partitioning of the components of the theory. [Pg.302]

Expressing this theory shifts the emphasis of creating specific knowledge for each problem formulation, to developing pieces of theory for more general problems. The method allows the computer to put these pieces together, based on the specific details of the problem, and the opportunities that the problem solving reveals. [Pg.314]

To complete the explanation of why GP effects cancel in the ICS, we need to explain why the 2-TS paths scatter into negative deflection angles. (It is well known that the 1-TS paths scatter into positive deflection angles via a direct recoil mechanism [55, 56].) We can explain this by following classical trajectories, which gives us the opportunity to illustrate a further useful consequence of the theory of Section II. [Pg.27]

An important departure from the previous theory arises from the fact that portions only of the polymer molecules, and never an entire molecule, occur within a volume element. It will be recalled that, in the estimation of the total number of configurations in the entire solution, one segment (the first one in the chain) of each molecule was allowed the opportunity to locate in any vacant cell of the lattice. [Pg.520]
