Details such as the

initial desorption of a nitrogen adlayer and the formation of the Ga monolayer, bilayer, and droplets are monitored using RHEED and related to Ga flux and shutter cycles. The suggested model increases the understanding of the surface kinetics of GaN, provides an indirect method of monitoring the kinetic evolution of these surfaces, and introduces a novel method of in situ growth rate determination.”
“The various monovinly-functional polyhedral oligomeric silsesquioxane (POSS) monomers had been copolymerized with ethylene (E) using rac-Et(Ind)(2) ZrCl2 and a modified methylaluminoxane (MMAO) cocatalyst. The unreacted SB273005 nmr POSS monomer could be removed completely by washing the copolymerization product with n-hexane. And the copolymers were characterized with H-1 NMR, TEM, DSC, TGA, and GPC to know the composition, thermal properties, molecular weight and its distribution, respectively. According to H-1 NMR data, the monomer reactivity ratios of various POSS monomers were calculated by the Fineman-Ross and Kelen-Tudos methods. Thermogravimetric analysis of E/POSS copolymers exhibited an improved thermal stability

with a higher degradation temperature and char yields, demonstating that the inclusion LY2090314 of inorganic POSS nanoparticles made the organic polymer matrix more thermally robust. (C) 2008 Wiley Periodicals, Vorinostat Inc. J Appl Polym Sci 111: 2697-2702, 2009″
“Red algae (RA) film containing grapefruit seed extract (GSE) was used as a wrapping film for cheese and bacon. RA film containing 1% GSE was prepared to inhibit the growth of pathogenic bacteria such as Escherichia coli O157:H7 and Listeria monocytogenes. Wrapping of cheese

and bacon with the film decreased the populations of E. coli O157:H7 and L. monocytogenes. After 15 days of storage, wrapping of cheese with the RA film reduced the populations of E. coli O157:H7 and L. monocytogenes by 1.21 and 0.85 log CFU/g, respectively, compared to control. Bacon wrapped with the RA film also decreased the populations of E. coli O157:H7 and L. monocytogenes by 0.45 and 0.76 log CFU/g, respectively. Wrapping of bacon with the RA film decreased peroxide and thiobarbituric acid values. These results suggest that RA film containing GSE is a useful wrapping material for extending the shelf lives of cheese and bacon.”
“BiFeO3 (BFO), BiFe1-xTixO3, and BiFe0.9Ti0.05Co0.05O3 thin films were deposited on Pt/TiO2/SiO2/Si substrates by chemical solution deposition. BFO film has distorted rhombohedral R-3c structure and in BiFe1-xTixO3 (104)/(110) reflections broadened suggesting limited grain growth with Ti substitution. The surface roughness (rms) decreased in the case of Ti substituted BFO. Up to 5% Ti in the lattice reduces the leakage current substantially.
