XPS, SEM and TEM studies were made on coal, non-coal, and shock-loaded pyrites that had been experimentally weathered under high relative humidity. Reactivity (oxidation) of the different pyrite samples may be related to their stacking fault densitie

The effects of relative humidity and oxygen partial pressure on the relative rates of surface oxidation of pyrites derived from various coal seams have been measured using X-ray photoelectron spectroscopy (XPS). The surface oxidation rate of the coal

Porcine embryos (1-, 2- and 4-cell) were cultured in a basal medium consisting of Krebs-Ringer bicarbonate buffer supplemented with oviductal fluid and several growth factors and observed for further development. Oviducts were flushed at either 48 h

The objective of this study was to evaluate the level of platelet-activating factor [1-O-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine; PAF] content in spermatozoa between two groups of boars that differ in farrow rate percentages. The boar farrow ra

Highly reactive coal pyrites and unstable museum specimens are easily distinguished from the stable pyrites by the growth of white crystals that cover samples exposed to room atmosphere for short periods of time. Continued exposure to the atmosphere

In situ X-ray photoelectron spectroscopy (XPS or ESCA) was used to identify the nickel species on Ni/Al2O3 catalyst surfaces as a function of nickel weight loading. The ESCA results show that the only nickel species on the reduced catalyst surface is
