Energy density analysis

The correlation energy of the subsystem a, AE p2, has been estimated from the energy density analysis [45] with the subsystem MOs as follows ... 

Recently efficient techniques were developed to simulate and analyze polymer mixtures with Nb/Na = k, k > I being an integer. Going beyond meanfield theory, an essential point of asymmetric systems is the coupling between fluctuations of the volume fraction (j) and the energy density u. This coupling may obscure the analysis of critical behavior in terms of the power laws, Eq. (7). However, it turns out that one can construct suitable linear combinations of ( ) and u that play the role of the order parameter i and energy density in the symmetrical mixture, ... 

Thus taking into account the cohesion energy density allows essentially to improve upon results of correlation analysis on influence of medium properties on kinetics of oxidation of propanethiole by chlorine dioxide. At the same time a significance of this factor is indirect proof of radical stages in the process. 

Pyrolysis oil (bio-oil) is produced in fast and flash pyrolysis processes and can be used for indirect co-firing for power production in conventional power plants and potentially as a high energy density intermediate for the final production of chemicals and/or transportation fuels. Gas chromatographic analysis of the liqtrid fraction of pyrolysis products from beech wood is given in Table 3.6 (Demirbas, 2007). Biocmde resrrlts from severe hydrothermal upgrading (HTU) of relatively wet biomass and potentially can be used for the production of materials, chemicals,... 

All these fuels belong to a group of high-energy-density fuels with compact molecular structure rendered by the presence of pentacyclic cages. They are stable and nonvolatile at room temperature and pressure. Three formulations are solid and the fourth is a viscous liquid. Their S3mthesis and molecular structure analysis that uses X-ray crystallographic methods have been described by Marchand [5, 6]. Their molecular structure and physical properties are presented briefly below. Measured thermophysical and thermochemical properties follow. 

In the lineage of the methodology developed above, the ADA and the WDA are nonlocal extensions of the EDA formulation. In this sense, the TF model discussed in Section II. 1 is the EDA counterpart for the OF-KEDF. however, the vW model discussed in Section III. 1 is somewhat different, because the ansatz in Eq. (39) departs from the EDA ansatz in Eq. (23). For later convenience, we name the strategy in Section III. 1 the Semilocal-Density Approximation (SEDA). In the following, through a detailed analysis of the exchange energy density functional (XEDF) and the OF-KEDF, we shall see the classical WDA is actually closely related to the SEDA.
