Effect Of Oxygen

The effect of oxygen adsorption on the conductivity of PbTe films is studied. Pn junctions based on PbTe films are photosensitive in the IR spectral region with a maximum photosensitivity of 𝜆𝑚𝑎𝑥 microns. The tunneling mechanism of current flow through the pn junction is shown.

Effect Of Oxygen

There are practically no data in the literature on the combined effect of oxygen and bismuth impurities on the structural and physicochemical properties of nickel melts or heat-resistant alloys based on it. In the presented work, the state of pure nickel and nickel melts containing (0.005-0.01) bismuth and oxygen is considered in the process of refining from oxygen and bismuth impurities. The influence of these impurities on the structural and physicochemical properties was studied, which was evaluated by the parameters of the density and surface tension of the melts. In nickel melts with bismuth and oxygen, a compression effect and a negative deviation from Raoult’s law were observed. The effect of an increase in the surface tension of a nickel melt containing oxygen with an increase in the concentration of bismuth is found, which corresponds to the isotherm of desorption of excess substance from the surface into the bulk.

Effect Of Oxygen

To evaluate the effects of oxygen breathing at atmospheric pressure on pulmonary surfactant, cats, rabbits, and rats were continuously kept in 98% oxygen until death occurred. Pulmonary surfactant was extracted by mincing of the lung and by foam fractionation of the lung. Surface tension of the extracts was measured on a Wilhelmy balance. Lung extracts prepared by both methods from the cats and rabbits kept in oxygen had greater surface tension than lung extracts from control animals. Surface tension of extracts prepared by foam fractionation of lungs of rats kept in oxygen did not differ from that of extracts of lungs of control rats, whereas surface tension of extracts prepared by mincing lungs of rats kept in oxygen had minimum surface tension greater than that of lung extracts of control rats. This species difference in the effects of oxygen breathing on pulmonary surfactant may reflect a difference in the pathogenesis of oxygen intoxication. oxygen intoxication; surface tension Submitted on October 19, 1964
