The reaction of methanol with nearly-stoichiometric and oxygen-terminated surfaces of Cr2O3 was studied using thermal desorption spectroscopy and x-ray photoelectron spectroscopy. Dissociative adsorption of methanol occurs on the nearlystoichiometric surface and is attributed to the availability of cation-anion site pairs. An array of products including CH4, CH2O, CO, CO2, and H2 are produced a...

This study was conducted to determine true ileal AA digestibility coefficients and the endogenous AA outputs associated with barley samples for growing-finishing pigs using the regression analysis technique with dual digestibility markers. Six barrows, with 30.5 and 58.6 kg average initial and final BW, were fitted with a simple T-cannula at the distal ileum and fed six barley-based diets at cl...

The intent of this study was to establish a fecal sampling procedure for the indicator method (IM) to provide digestibility values similar to those obtained by the total collection (TC) method. A total of 24 pigs (52.6 ± 1.5 kg) were fed 1 of 4 diets with a 2 × 2 factorial arrangement of virginiamycin and phytase (PHY) added to a corn-soybean meal diet with no inorganic P supplement. Pigs were ...

The present work investigates the high temperature oxidation and corrosion behaviour of high entropy superalloys (HESA). A high content of various solutes in HESA leads to formation of complex oxides, however the Cr and Al activities of HESA are sufficient to promote protective chromia or alumina formation on the surface. By comparing the oxidation and corrosion resistances of a Ni-based supera...

Cr2O3 and Cr2O3–SiO2-TiO2 coatings are deposited on P265GH steel using atmospheric plasma spraying. The influence of silicon oxide—titanium oxide addition the surface morphology coatings, phase composition tribological properties under non-lubricated sliding conditions investigated. SiO2-TiO2 led to formation a more uniform reduce roughness coatings. X-ray diffraction (XRD) studies indicated th...

Measurements of the temperature dependence electrical resistance (R) and neutron powder diffraction (NPD) a Cr84.7Re15.3 alloy is reported. The magnetism originates from formation spin-density-wave (SDW) as result nesting between electron hole sheets at Fermi surface (FS). NPD revealed magnetic character SDW to be commensurate (C) with lattice Néel (TN) 560 ± 5K that correlates TN = 585 determi...
