ANN prediction of the efficiency of the decolourisation of organic dyes in wastewater by plasma needle
(Srpsko hemijsko društvo, Beograd, 2020)
In this paper, the results of decolourisation of Reactive Orange 16 (RO 16), Reactive Blue 19 (RB 19) and Direct Red 28 (DR 28) textile dyes in aqueous solution by plasma needle are presented. Treatment time, feed gas flow ...
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 ...
Synthesis, solvent interactions and computational study of monocarbohydrazones
(Springer International Publishing Ag, Cham, 2020)
Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For ...
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 ...
