Short-range order interactions

Short-range order interaction [40] (sometimes called configurational interaction or Fisher effect) can also occur. If, for example, the binding energy...

It has been assumed that u 0.1 in order to be far from the symmetrical regime. This means that the labeled chains merging at the crosslink are 9 times shorter than the external chains. One can first assume that the quantity S(q) is constant this means that there are short-range order interactions between the copolymer molecules as in classical liquids this is not reasonable and has practically the same effect as changing the value of the X parameter. Therefore, we have to introduce a q dependence of J((j) It can be assumed, as a simple approximation, that J(q) obeys an Ornstein Zernicke type of law and has the form ...

Advantages of small metal nanoparticles are (i) short range ordering, (ii) enhanced interaction with environments due to the high number of dangling bonds, (iii) great variety of the valence band electron structure, and (iv) self-structuring for optimum performance in chemisorption and catalysis. 

As the temperature is decreased, the chains become increasingly rigid zc then approaches 1 if we assume that there is only one fully ordered crystalline structure and Zconf for the liquid becomes smaller than 1. This means that, at this level of approximation, the disordered state becomes less favorable than the crystalline ground state. A first-order disorder-order phase transition is expected to occur under these conditions. Flory interpreted this phase transition as the spontaneous crystallization of bulk semiflexible polymers [12], However, since the intermolecular anisotropic repulsion essential in the Onsager model is not considered in the calculation, only the short-range intramolecular interaction is responsible for this phase transition. 

Anomalous X-ray diffraction or resonant scattering refers to the modification of its intensity due to absorption processes involving interactions between the X-ray beam and the atoms in the sample. This interaction combines the chemical and short-range order sensitivity of absorption with the long-range order sensitivity of diffraction. This results in a chemical selectivity, i.e. it is possible to differentiate elements with close atomic numbers or even cations with the same number of electrons like Rb+ and Sr2+... 

Short-range order ferromagnetic interactions have been reported for several compounds containing 1,2-dithiolene and 1,2-diselenolene complexes,252 254... 

Model of a molecular structure, which determines a mutual arrangement and interaction of atoms that form a molecule, molecular site, or a short-range order in a solid material. This is the area of molecular chemistry, stereochemistry, etc. A characteristic element of this level is the atom with prevailing interatomic interactions. 

The importance of interactions amongst point defects, at even fairly low defect concentrations, was recognized several years ago. Although one has to take into account the actual defect structure and modifications of short-range order to be able to describe the properties of solids fully, it has been found useful to represent all the processes involved in the intrinsic defect equilibria in a crystal (with a low concentration of defects), as well as its equilibrium with its external environment, by a set of coupled quasichemical reactions. These equilibrium reactions are then handled by the law of mass action. The free energy and equilibrium constants for each process can be obtained if we know the enthalpies and entropies of the reactions from theory or...
