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 ...
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 ...

Phenomenology of a formation of a honeycomb-like structure during copper electrodeposition
(Journal of Solid State Electrochemistry, 2007)
In this paper, the phenomenology of a formation of a honeycomb-like structure was considered. Copper deposits obtained at overpotential of 1000 mV were examined by scanning electron microscopy (SEM) technique. It was shown ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
