✦ Synopsis

Attempts were undertaken to explain the influence of polyethylene glycol on electrochemical zinc behaviour in alkaline solution. The average molecular weight of PEG was from a few tens to 900. The methods of anodic and cathodic polarization curves and galvanostatic single pulses were used. It was observed that some glycols (especially PEG 600) shift the cathodic curves to more negative potentials. An increase of exchange current was also found for zinc with PEG 600 admixture. It seems that the activity of polyethylene glycol can be explained by its adsorption at the zinc surface.

## Abstract The effects of oxygen vacancies and zinc interstitials on the structure and energy of zinc oxide were studied with the semiempirical MO method MSINDO. Cyclic clusters were chosen as model systems. Single and multiple removal of oxygen atoms and zinc interstitials in zinc oxide served to

The dissolution rates of the two polymorphic forms of sulfathiazole containing polyethylene glycol 4000 were significantly different in water. The effect of agitation on the dissolution rates also was studied. At higher stirring speeds, the dissolution rates of the stable form were affected more tha
