The Impact

ABSTRACTWe examine how stress has the potential to shape the character of the electron transport that occurs within ZnO. In order to narrow the scope of this analysis, we focus on a determination of the velocity-field characteristics associated with bulk wurtzite ZnO. Monte Carlo simulations of the electron transport are pursued for the purposes of this analysis. Rather than focusing on the impact of stress in of itself, instead we focus on the changes that occur to the energy gap through the application of stress, i.e., energy gap variations provide a proxy for the amount of stress. Our results demonstrate that stress plays a significant role in shaping the form of the velocity-field characteristics associated with ZnO. This dependence could potentially be exploited for device application purposes.

Gravimetric Procedure

Abstract Reasons are advanced for the unsatisfactory nature of some of the older methods for the determination of very small amounts of zinc in compounded rubber, particularly in latex mixings. The polarographic technique offers a possible solution, but most of the commoner electrolytes for the electroreduction of this metal are alkaline, and give rise to similar errors as are met in the gravimetric procedure. The development of a suitable acid electrolyte was therefore undertaken, and ways of dealing with likely interferences were examined. The electroltye finally recommended is a potassium thiocyanate-ammonium acetate buffer solution; iron, when present, is reduced to the ferrous condition by potassium iodide. The method was used to determine zinc oxide in a series of mixings of known composition ranging from 0.8 to 40 per cent. In all except the highest proportions of zinc oxide, the figures obtained agree well with the theoretical.

Abstract A method has been developed for determining 1 μg of mercury in 100 ml of aqueous acid solution with a precision of ± 0.25 μg. In the method, the mercury is adsorbed by anion resinloaded paper and determined by X-ray emission spectroscopy. The method gave 75—125% recoveries of 1 μg of mercury from acid solutions containing 10 g of sodium sulfate, sodium chloride, iron oxide, magnesium carbonate, and calcium carbonate, and satisfactory recoveries from the HCl extract of carbon, barium sulfate, chromic oxide, bentonite, kaolin, talc, titanium dioxide, and magnesium stearate. Substantial changes in flow rate or acid concentration seem to have little effect on mercury absorption from HC1 solution. Mercury in zinc oxide or bismuth oxychloride cannot be determined by this technique.
