Partitioning and purification of cellulases in aqueous two-phase system
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
Aqueous two-phase systems can be formed by mixing the solutions of two mutually incompatible polymers or polymer and salt above critical concentrations and represent media that are very well suited for the separation and ...
Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
Polyethersulfone membranes with integrated adsorbent particles for heavy metals capture
(Belgrade, Serbia : Society of Physical Chemists of Serbia, 2014)
Novel polyethersulfone membranes with integrated submicron adsorbent particles were prepared by combining photoirradiation with liquid phase inversion. These particles consist of cross-linked poly(glycidyl methacrylate-c ...
Designing of manufacturing process of reformer integrated in system with HTPEM fuel cell stack
(Belgrade : Faculty of Mechanical Engineering, Innovation Center, 2017)
In this paper is shown designing of manufacturing process of reformer in polymeric electrolyte membrane
(PEM) fuel cell. The process is based on reformer modelling, analyzing of reforming initial geometry and
change of ...
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 ...
Thermal Resistance of Alkali Activated Binders Synthesized Using the Fly Ash and Steel Slag
(Belgrade : Materials Research Society of Serbia, 2015)
The thermal resistance of alkali-activated binders based on fly ash (FA), electric arc furnace slag (EAFS) and their FA/EAFS blends was assessed. Compressive strengths of samples before and after firing were measured. The ...
Antibacterial activity of clove essential oil against food-borne pathogenic bacteria
(UDRUŽENJE MIKROBIOLOGA SRBIJE, 2018)
INTRODUCTION: Food infection and intoxication are still a major problem worldwide, in spite of the modern methods used to preserve food. Application of synthetic preservatives may lead to negative health consequences and ...
Exploiting the Nonlinear Frequency Response Method to Evaluate the Potential of Forced Periodic Operation of Reactors
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2016)
Forced periodic operation of chemical reactors possess significant potential to improve numerous performance criteria. The corresponding analysis of reaction systems and the estimation of the magnitude of possible performance ...
