Study of lipase-catalyzed synthesis of ascorbyl oleate using response surface methodology
(6th Central European Congress on Food, CEFood 2012, 2012)
L-ascorbic acid has good antioxidative properties but its efficiency in stabilizing fats and oils in products with high lipid content is negligible due to its hydrophilic characteristics. On the other hand, fatty acid ...
Effect of fermentation by Streptomyces sp. on antioxidant properties of spent coffee extracts
(6th Central European Congress on Food, CEFood 2012, 2012)
During espresso coffee preparation large amounts of spent coffee residues are produced and discarded daily as a part of the communal waste. However, there is a great potential in recycling this type of waste for extraction ...
Synthesis of ethyl cinnamate catalyzed by lipase B from Candida antarctica
(6th Central European Congress on Food, CEFood 2012, 2012)
Cinnamic acid and its esters are widespread throughout plant kingdom and therefore, they are common components of our daily diet. Ethyl cinnamate has been approved by FDA for direct addition to food for human consumption. ...
Hardness response and adhesion of thin copper films on alloy substrates
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2017)
Microhardness test is the most commonly used method for assessing the mechanical properties of thin films.This testing method uses controlled contact at a single point of an indenter and chosen material which induces the ...
Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
Geopolymer materials based on the electric arc furnace slag
(Belgrade : Materials Research Society of Serbia, 2013)
The remelting of iron and steel scrap in the electric arc furnaces generates the non-hazardous waste – electric arc furnace slag (EAFS), which can be disposed of to appropriate landfills. Currently, this slag found its ...
Homogeneous-heterogeneous catalytic effect of CaO · ZnO/K2CO3 during biodiesel synthesis
(Czech Society of Chemical Engineering, 2014)
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to 3% NaCl has been investigated. This system was also tested for cathodic protection and it has proven more efficient ...
Electrochemical determination of ascorbic acid using electrochemically deposited polyaniline
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2014)
Electroconducting polymers are promising materials to be used in various fields including: batteries, capacitors, electronic devices, corrosion, biosensors and sensors[1,6]. Polyaniline is probably the most investigated ...
Evaluation of possible performance improvement through periodic operation for the reaction of acetic acid anhydride hydrolisis
(European Symposium on Chemical Reaction Engineering (ESCRE 2015), Munich, Germany, 2015)
The nonlinear frequency response (NFR) method is a relatively new, fast and easy, analytical method for evaluating the performance of forced periodically operated chemical reactors. The method has been introduced in our ...
