Antioxidant activity of PLA/PCL films loaded with thymol and/or carvacrol using scCO2 for active food packaging
(Food Packaging and Shelf Life, 2020)
Present study was aimed to produce biodegradable films with antioxidant activity for active food packaging. Films of poly(lactic acid) (PLA) with 5 wt% of poly(ε-caprolactone) (PCL), denoted as PLA-5, were loaded with ...
Characterization of PM(2.5)sources in a Belgrade suburban area: a multi-scale receptor-oriented approach
(Springer Heidelberg, Heidelberg, 2020)
Designated as the most harmful for health, PM(2.5)aerosol fraction was a subject of our study. It was collected for all four seasons during 2014/15 in the suburban area of Belgrade (Serbia) and analysed for Al, Si, P, S, ...
The advantage of ultrasound during electrodeposition on morphology and corrosion stability of Zn-Co alloy coatings
(Taylor & Francis Ltd, Abingdon, 2020)
The influence of ultrasound agitation on the properties of electrodeposited Zn-Co coatings was analysed and compared with coatings deposited by using magnetic stirring. The morphology and chemical composition of the deposits ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH Verlag Gmbh, Weinheim, 2020)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
Porous cordierite-supported polyethyleneimine composites for nickel(II) and cadmium(II) ions removal
(Desalination Publ, Hopkinton, 2020)
Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, ...
A Three-electrode gas arrester for low voltage isolation coordination
(Elsevier Sci Ltd, Oxford, 2020)
