Recent trends in bioethanol production / Novi trendovi u proizvodnji bioetanola
(Association of Chemical Engineers of Serbia, 2011)
The rapid depletion of the world petroleum supply and the increasing problem of greenhouse gas effects have strengthened the worldwide interest in alternative, nonpetroleum sources of energy. Bioethanol accounts for 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 ...
Electrochemical synthesis and corrosion behavior of thin polyaniline film on mild steel, copper and aluminum / Sinteza i koroziono ponašanje polianilina na mekom čeliku, bakru i aluminijumu iz benzoatnih rastvora
(Association of Chemical Engineers of Serbia, 2011)
The electrochemical synthesis of polyaniline (PANI) on mild steel, aluminum and copper from the sodium benzoate solutions has been investigated. It has been shown that thin, highly adherent, polyaniline films on the ...
The qualitative determination of oseltamivir phosphate in Tamiflu® capsule by cyclic voltammetry / Kvalitativno određivanje oseltamivir-fosfata u Tamiflu® kapsulama pomoću ciklične voltametrije
(Association of Chemical Engineers of Serbia, 2011)
A gold electrode was used in the voltammetric determination of oseltamivir phosphate standard in 0.05 M NaHCO3. Oseltamivir phosphate as a standard and as a component of Tamiflu® capsule exhibited the identical cyclic ...
