Surface analysis by x-ray photoemission spectroscopy demonstrated that the surface region of the films is non-stoichiometric, being significantly rich in tin and antimony and deficient in both indium and oxygen. Both electron mobility and carrier concentration steeply decrease with increasing antimony content in the films. The temperature dependence

of the electrical transport properties was explained by a model in which for x >= 0.5, the carrier transport is governed by percolation conduction over the distribution of potential barriers around the conduction band edge while degenerate electronic conduction is attained at x < 0.5. The optical bandgap value decreases from 3.15 to 2.92 eV with increasing antimony content from 0 to 1. (C) 2011 American Institute of Physics. [doi:10.1063/1.3605552]“
“Dried corn distillers grains with solubles (DDGS) fed to swine may adversely affect carcass quality due to the high concentration Vorinostat in vivo of unsaturated fat. Feeding CLA enhances pork quality when unsaturated fat is contained in the diet. The effects of CLA on growth and pork quality were evaluated in pigs fed DDGS. Diets containing 0, 20, or 40% DDGS were fed to pigs beginning 30 d before slaughter. At 10 d before slaughter, one-half of each DDGS treatment group was fed 0.6% CLA or 1% choice white grease. Carcass

data, liver- and backfat-samples were collected at slaughter. Longissimus muscle area, 10th-rib back-fat depth, CX-6258 supplier last rib midline backfat depth, LM color, marbling, firmness and drip loss, and bacon collagen content were GW4869 solubility dmso not altered by DDGS or CLA. Outer layer backfat iodine values were increased (P = 0.05) with DDGS feeding and were 65.07, 69.75, and 74.25 for 0, 20, and 40% DDGS, respectively. Addition of CLA decreased (P = 0.05) outer layer backfat iodine values from 71.11 to 68.31. Diets containing DDGS decreased (P = 0.05) percent lean tissue contained in bacon from 48% for controls to 38% for pigs fed 40%. Abundance of fatty acid synthase, carnitine palmitoyl transferase Ia,

acetyl-CoA-carboxylase, stearoyl-CoA desaturase, and glycerol-3-phosphate dehydrogenase mRNA in adipose or liver were not different (P > 0.05) for pigs fed DDGS. Feeding CLA decreased (P = 0.05) the. 9 desaturase index in adipose tissue. The data indicate that decreased carcass firmness with DDGS feeding is not reflected by changes in lipogenic gene expression. Feeding 20% or more DDGS to finishing swine decreases bacon leanness, but inclusion of 0.6% CLA in the finishing diet can partially reverse these effects.”
