HPLC analysis revealed that P agglomerans D23W3 could convert DB

HPLC analysis revealed that P. agglomerans D23W3 could convert DBT to 2-hydroxybiphenyl (2-HBP) via the 4S pathway and that it could degrade 93% of the 100 ppm DBT within 24 h of culture. In addition P. agglomerans D23W3 could also desulfurize 4,6-dimethyl DBT and benzothiophene

which are among the most difficult DBT derivatives to be removed by HDS. Further, adapted cells of P. agglomerans D23W3 were found to remove 26.38-71.42% ALK phosphorylation of sulfur from different petroleum oils with highest sulfur removal from light crude oil. Therefore, P. agglomerans D23W3 has a potential for the BDS of the petroleum oils. (C) 2010 Elsevier B.V. All rights reserved.”
“Hollow BiFeO(3) nanoparticles ATM signaling pathway were synthesized by an electrospray route for

the first time. The phase purity and structure have been investigated by x-ray diffraction and Raman spectroscopy. Transmission and scanning electron microscope investigations revealed that the as-obtained BiFeO(3) hollow spheres were polycrystalline, with a shell thickness of 35 nm. The formation mechanism can be possibly explained by Ostwald ripening. Raman spectra have verified decreased vibrational frequencies in BiFeO(3) nanoparticles. These hollow and core-shell multiferroic nanoparticles exhibit significantly enhanced ferromagnetism from 5 to 600 K due to a broken spiral spin structure. The ferroelectricity of hollow BiFeO(3) particles exhibits a lower switching electric

field, which is confirmed by Kelvin probe force microscopy. 3-MA (C) 2011 American Institute of Physics. [doi:10.1063/1.3561377]“
“Measurements of current-voltage curves at room temperature, in nitrogen and nitrogen-acetone atmospheres have clearly demonstrated the rectifying behavior of the Al/PPy-DBSA/Au structure. For this structure, the values of 0.82 eV and 2.31, for the barrier height and ideality factor, respectively, have been obtained in nitrogen atmosphere, while at concentration of 120 ppm of acetone, the corresponding values were 0.74 eV and 2.07. The barrier height value obtained from I-V characteristic is lower than the barrier height value obtained from C-V measurements. The discrepancy can be due to the existence of an interfacial oxide layer between the semiconductor and Schottky contact metal. The density distribution curves of the interface states vary in the range (0.55-E-V) to (0.84-E-V) for pure nitrogen, and (0.45-E-V) to (0.60-E-V) in atmosphere with acetone. The interface state density has an exponential rise with bias from the midgap towards the top of the valence band of the PPy-DBSA. (C) 2011 Wiley Periodicals, Inc.
