Partial Pressures

Polycrystalline ZnO thin films are prepared by the co-sputtering method under different oxygen partial pressures. Films deposited in pure argon gas exhibit ferromagnetism, whereas other films deposited under different oxygen partial pressures are diamagnetism. XPS results show the presence of Zn interstitial and oxygen vacancy in all of samples. Further analysis indicates that Zn interstitial may play an important role in triggering magnetic order on the undoped ZnO thin films by inducing an alteration of electronic configuration.

AbstractThe effect of high density polyethylene (HDPE) addition on the pre-reduction of Mn3O4 to MnO by metallurgical coke (Coke) has been investigated through experiments conducted in a laboratory horizontal tube furnace coupled with off-gas analysis through an infrared (IR) gas analyser. Composite pellets of Mn3O4 with Coke, HDPE and blends of Coke with HDPE (in three different proportions) were rapidly heated at 1150 °C under pure argon gas and the off gas was analysed continuously for CO, CO2 and CH4. The extent of pre-reduction of Mn3O4 to MnO was then calculated by mass balance for removable oxygen. The results showed improvements in the extent of pre-reduction of Mn3O4 to MnO when coke is blended with HDPE. The time for complete pre-reduction was found to decrease with an increase in the amount of HDPE that was blended with coke. A decrease in CO2 emissions was observed with HDPE addition.

Measured values of breakdown electric fields in pure argon gas are presented. Measurements were made in two resonant cavities at a frequency of 2800 Mc./sec. and for pressures varying from 4 × 10−2 to 200 mm. of mercury. The present results are in agreement with those of Krasik, Alpert, and McCoubrey.
