The peculiarities of electrochemical deposition and morphology of Zn-Mn alloy coatings obtained from pyrophosphate electrolyte / Specifičnosti elektrohemijskog taloženja i morfologija Zn-Mn prevlaka dobijenih iz pirofosfatnog elektrolita
(Association of Chemical Engineers of Serbia, 2011)
The first successful attempt to electrodeposit Zn-Mn alloy coatings from alkaline bath was made only a few years ago. In this kind of solution, potassium pyrophosphate (K4P2O7) serves both as a complexing agent and as the ...
Immobilization of alginate-PAC on sepabeads EC-HA support / Imobilizacija penicilin-acilaze modifikovane derivatom alginata na sepabeads EC-HA nosač
(Association of Chemical Engineers of Serbia, 2011)
Penicillin acylase (PAC) is an important industrial enzyme for the production of many β-lactam antibiotics. It is capable of catalyzing the hydrolysis of penicillin G (Pen G) to generate phenylacetic acid (PAA) and ...
Obtaining of the antioxidants by supercritical fluid extraction / Izolovanje antioksidanasa postupkom natkritične ekstrakcije
(Association of Chemical Engineers of Serbia, 2011)
One of the important trends in the food industry today is demand for natural antioxidants from plant material. Synthetic antioxidants such as butylated hydroxytoluene (BHT), and butylated hydroxyanisole (BHA) are now being ...
