The effects of various copolymerization conditions on the monomer conversion

were reported. The copolymers were characterized by means of IR, (1)HNMR, and gel permeation chromatography. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 113: 3196-3201, 2009″
“The structure of orthorhombic (alpha ”) martensitic phase of Ti-8Nb, Ti-12Nb. and Ti-16Nb alloys has been investigated using Rietveld refinement of x-ray diffraction data The chemical analysis data have been used to determine the site occupancy of initial models. A limit of AZD8931 in vitro the Wyckoff positions has been proposed based on the symmetry of the Cmem space group, Which allows

the movement of atoms without breaking the space group symmetry This has also been incorporated in the initial models of experimental alloys, and accordingly Wyckoff positions have been refined. It has been observed that the atoms move along the Y-axis (parallel to the b-axis) and the movement of atoms increases with increase in Nb concentration. The formation of orthorhombic (alpha ”) phase has been explained based on the movement of atoms along the Y-axis This ill turn breaks the hexagonal symmetry and forms an orthorhombic phase.

“The edible ascidian, sea squirt Halocynthia roretzi (Drasche) is marine buy MK-0518 invertebrate that is a valuable source of foods and bioactive compounds. A severe disease of the sea squirt characterized by degeneration of tunic fibers formed of bundled cellulose microfibrils has occurred. We hypothesized that bacteria lyse the cellulose fibril structure, cellulase activity may be a causative agent of the disease. Among HM781-36B mw the bacteria isolated from diseased sea squirt, Pseudoalteromonas sp. NO3 had cellulase

activity based on a Congo red overlay assay and starch-reducing activity. Sea squirts exhibited 40-100% cumulative mortality after injection with Pseudoalteromonas sp. NO3 using doses of 2×10(6)-2×10(8) colony forming unit (CFU)/individual. Dead sea squirts possess thinner and ruptured tunics, which were similar to natural outbreaks. These results suggest that Pseudoalteromonas sp. NO3 possessing cellulase activity is one of the causes of tunic softness syndrome in sea squirt.”
“By means of the wet chemical Surface modification, the surface of Fe2O3 was modified by vinyltrimethoxysilane (VTMS). Infrared spectroscopy (IR) was used to investigate the structure of the modified Fe2O3, and the result showed that VTMS has been attached onto the surface of Fe2O3.
