Transparent and conductive/semiconductive undoped indium oxide (InOx) thin films were deposited at room temperature. The deposition technique used is the radio frequency (rf) plasma enhanced reactive thermal evaporation (rf-PERTE) of indium (In) in the presence of oxygen. The influence of oxygen partial pressure on the properties of these films is presented. The oxygen partial pressure varied b...

Modified atmosphere packaging (MAP) is commonly applied to extend food shelf-life. Despite growth of a wide variety of fungal contaminants has been previously studied in relation to modified-atmospheres, few studies aimed at quantifying the effects of dioxygen (O2) and carbon dioxide (CO2) partial pressures on conidial germination in solid agar medium. In the present study, an original culture ...

In industrial biotechnology, microbial cultures are exposed to different local pressures inside bioreactors. Depending on the microbial species and strains, the increased pressure may have detrimental or beneficial effects on cellular growth and product formation. In this review, the effects of increased air pressure on various microbial cultures growing in bioreactors under moderate total pres...

Dense membranes of mixed-conducting perovskite-type oxides Lao.sSro.4Co,,8Fe,,,0~ and Lac,aBa&oo.aFe,,,O~ were used for methane coupling by application of pressure-driven O2 permeation. High operating temperatures, typically above 8OO”C, were needed to obtain reasonable oxygen fluxes. Conversions were small (l-3%). Both compositions showed comparable C2 selectivities at low methane partial pres...

1. A method is described for measuring tissue oxidation under reduced barometric pressure. 2. The oxygen uptake of yeast is diminished by low barometric pressures to a greater extent than by a reduction of the partial pressure of oxygen, to a corresponding degree, at atmospheric pressure. 3. This effect of low pressure is not observed with certain in vitro oxidation systems. 4. The anaerobic re...

This article examines how institutional pressures affect the adoption of green IS&IT across organizations. From the natural-resource-based perspective, it examines green IS&IT practices with strategic foci on pollution prevention, product stewardship, and sustainable development. Each category incorporates the separate roles played by IT (as a problem) and IS (as a solution). The partial least ...

Using the Langmuir probe method, the reactive plasma parameters were studied in different ratios of oxygen and nitrogen concentrations in a DC cylindrical discharge device.The plasma parameters such as plasma potential, electron density and electron temperature wereextracted from the current-voltage characteristic’s curve of Langmuir probe to find the optimum conditions for deposit the oxy...

Human erythrocytes were exposed to high concentrations of methane and nitrogen through the application of elevated partial pressures of these gas molecules. Cell leakage (haemolysis) was measured for cells exposed to these gases under a wide range of experimental conditions. Application of methane produces haemolysis at pressures far below the hydrostatic pressures known to disrupt membrane or ...
