Purpose: Developing mean-field theory for a 2D two-band model including electron – phonon interaction and the extended Falicov-Kimball model involving electron/hole – phonon interaction. Studying the properties of electronic systems in EI state through investigating the above models. Then, we compare the nature of each condensation state on both sides of the BCS – BEC crossover or the competition with the CDW state.

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Mechanical properties and thermal stability were determined by tensile analysis and thermogravimetric analysis (TGA), respectively.

Cytochrome P450BM3is a self-sufficient fatty acid mono-oxygenase consisting of a diflavin (FAD/FMN) reductase domain and a heme domain fused together in a single polypeptide chain. The multidomain structure makes it an ideal model system for studying the mechanism of electron transfer and for understanding P450 systems in general. Here we report the redox properties of the cyto-chrome P450BM3 wild-type holoenzyme, and its isolated FADreductase andP450 heme domains, when immobilized in a didodecyldimethylammonium bromide film cast on an edge-plane graphite electrode....
