Analysis of forced periodic operations of non-isothermal CSTR with modulation of inlet concentration and temperature
(8th European Congress of Chemical Engineering (ECCE 2011), Berlin, Germany, 2011)
One way to achieve process intensification is to operate the process in a periodic way, in order to obtain better average performance compared to the optimal steady-state operation. The source of the possible improvement ...
Design of a polyaniline based biosensor electrode for glucose: A comparative study of two immobilized systems
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
The present study compares the results of two different methods employed for preparation of polyaniline based glucose biosensor with respect to enzyme loading, biosensing efficiency and potential stability. Kinetic analysis ...

Microindentation hardness testing of different composite systems with thin electrodeposited nickel and copper films
(Belgrade : Military Technical Institute, 2012)
Thin Ni and Cu films with fine-grained structures have been electrodeposited from self-made sulphamate-based and sulphate-based electrolytes, respectively. DC electrodeposition of Ni films was performed on single crystal ...
The effect of Ni content on passivation of copper anodes with non-standard chemical composition
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes ...
Novel negatively-charged ultrafiltration membranes made by a combination of immersion precipitation and photopolymerization
(Belgrade : Serbian Chemical Society, 2013)
Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity ...
The influence of current density on charge/discharge characteristics of polyaniline electrode
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
