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 ...
Theoretical and experimental study of small potassium-bromide KnBr(0,1+) (n=2-6) and KnBrn-1(0,1+) (n=3-5) clusters
(Elsevier Science Sa, Lausanne, 2020)
In the present paper, the results of combined theoretical and experimental investigation of small non-stoichiometric bromine-doped potassium clusters are reported. Potassium-bromide clusters were obtained by the Knudsen ...
Mechanical Oscillations in 2D Collective Cell Migration: The Elastic Turbulence
(Frontiers Media Sa, Lausanne, 2020)
Various types of mechanical waves, such as propagative waves and standing waves, are observed during 2D collective cell migration. Propagative waves are generated during monolayer free expansion, whereas standing waves are ...
Photolysis of insecticide methomyl in various solvents: An experimental and theoretical study
(Elsevier Science Sa, Lausanne, 2020)
This study describes photolysis of 1 x 10(-4) M methomyl solution in deionized water and in eleven organic solvents, both polar and nonpolar: methanol, ethanol, n-propanol, isopropanol, sec-butanol, tert-butanol, isobutanol, ...
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 ...
Thin-layer chromatography on reversed phase in the characterization of retention behaviour, lipophilicity, and pharmacokinetics of cyanoacetamide derivatives
(Journal of the Chilean Chemical Society, 2020)
Biological activity of a molecule is closely related to its lipophilicity. This significant parameter was determined for a group of potentially bioactive N-(4-phenylmonosubstituted)-2-cyanoacetamides applying thin-layer ...
A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier Sci Ltd, Oxford, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO supported ...
New Eco-Friendly Xanthate-Based Flotation Agents
(MDPI, Basel, 2020)
An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as ...
Lead isotope ratios as tool for elucidation of chemical environment in a system of Macrolepiota procera (Scop.) Singer - soil
(Springer Nature, 2020)
The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real ...
Applying concept of 3d printing concrete in wind tower construction / Primena koncepta 3d štampe betona u izradi vetrogeneratora
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Although a most prominent material in contemporary construction practice due to its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a ...
