Structural, Mechanical and Electrical Characteristics of Copper Coatings Obtained by Various Electrodeposition Processes
(Electronics, 2022)
Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Srpsko hemijsko društvo, Beograd, 2018)
The MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99-1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
The production of cellulase from the waste tobacco residues remaining after polyphenols and nicotine extraction and bacterial pre-treatment
(Srpsko hemijsko društvo, Beograd, 2019)
Agricultural by-products are generated in large amounts in various industries, creating a serious disposal problem. Valorisation of tobacco waste for the extraction of value-added compounds and the production of enzymes ...
Covalent immobilization of enzymes on Eupergit® supports: Effect of the immobilization protocol
(Methods in Molecular Biology, 2017)
A selection of best combination of adequate immobilization support and efficient immobilization method is still a key requirement for successful application of immobilized enzymes on an industrial level. Eupergit® supports ...
Evaluation of the impact of critical quality attributes and critical process parameters on quality and stability of parenteral nutrition nanoemulsions
(Elsevier, Amsterdam, 2017)
The aim of this study was to develop, characterize and evaluate concentrated nanoemulsions (20%) for parenteral nutrition. Those systems were developed by the high-pressure homogenization method. Optimal conditions for the ...
Influence of cold-rolling deformation and annealing temperature on the grain growth of al-4%mg-mn alloy
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2020)
The propensity of an alloy toward an abnormal grain growth (AGG) severely limits the annealing temperature range, capability for hot forming, and deteriorates mechanical properties. In this work, the results of a study of ...
Employees competitiveness development as a element of human resource management: Some special approach to textile industry / Razvoj kompetencija zaposlenih kao element menadžmenta ljudskih resursa - sa posebnim osvrtom na tekstilnu industriju
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2016)
Knowledge, ability and skills of every employees are his competitiveness. Technical and technology progress causes changes, and because of that demands of competitiveness become bigger and bigger. There are distinctions ...
Influence of the content of hard segments on the properties of novel urethane-siloxane copolymers based on a poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone) triblock copolymer
(Journal of the Serbian Chemical Society, 2011)
A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a alpha,omega-dihydroxy-[poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone)] (alpha,omega-dihydroxy-PCL-PDMS-PCL) ...
Optimization and kinetic study of anthraquinone dye removal from colored wastewater using soybean seed as a source of peroxidase
(Macedonian Journal of Chemistry and Chemical Engineering, 2020)
As water contamination emerges as a serious threat to the environment, ventures for cleaner and sustainable solutions are continuously being developed. The present study investigates the ability of crude peroxidase extract ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
