Mixtures of methanol and 2-propanol as a potential fuel for direct alcohol fuel cells / Smeša metanola i 2-propanola kao potencijalno gorivo u gorivim spregovima sa alkoholom
(Serbian Chemical Society, Belgrade, 2007)
The electrochemical oxidation of methanol, 2-propanol, and their mixtures was investigated on a Pt/C thin film electrode in acid solution. It was confirmed that the oxidation of 2-propanol commences at less positive ...
Utilization of baker's yeast (Saccharomyces cerevisiae) for the production of yeast extract: Effects of different enzymatic treatments on solid, protein and carbohydrate recovery / Primena pekarskog kvasca (Saccharomyces cerevisiae) za dobijanje kvaščevih ekstrakata - uticaj različitih parametara enzimske hidrolize na sadržaj suve materije, proteina i ugljenih hidrata
(Serbian Chemical Society, Belgrade, 2007)
Yeast extract (YE) was produced from commercial pressed baker's yeast (active and inactivated) using two enzymes: papain and lyticase. The effects of enzyme concentration and hydrolysis time on the recovery of solid, protein ...
Contribution of textile technology to the development of modern compression bandages
(CI and CEQ, 2007)
Although compression therapy is a key factor in the successful treatment of some circulatory problems in lower limbs, this form of therapy includes some risks if used inappropriately. Based on deliberate application of ...
