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 ...
Evaluation of soft tissue regenerative processes after subcutaneous implantation of silver/ poly(vinyl alcohol) and novel silver/poly(vinyl alcohol)/graphene hydrogels in an animal model
(Acta Veterinaria-Beograd, 2021)
A newly produced biomaterial is necessarily subject of standards, which are performed in vivo on animal models. For the evaluation of soft tissue regenerative possibilities after subcutaneous implantation of biomaterials ...
Efficiency of calcium hydroxide removal techniques from simulated internal root resorptions - in vitro study
(Srpski Arhiv Za Celokupno Lekarstvo, 2021)
Introduction/Objective Calcium hydroxide (CH) is the medicament of choice in endodontic treatment of internal root resorptions. The aim of the study was to compare the effectiveness of three different techniques for CH ...
Statistical optimization of bioethanol production from waste bread hydrolysate
(Journal of the Serbian Chemical Society, 2021)
A recent trend in sustainable bioethanol production is the use of agricultural waste or food waste as an inexpensive and the most available feedstock. Bread waste is the major food waste that could be successfully used for ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
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 ...
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 ...
Removal of Fe2+, Zn2+ and Mn2+ from the mining wastewater by lemon peel waste
(Srpsko hemijsko društvo, Beograd, 2020)
This study is aimed to evaluate the possibility of lemon peel, as an agro-industrial waste, to remove Fe2+, Zn2+ and Mn2+ from single aqueous solutions and mining wastewater. For this purpose, the influence of various ...
Improvement and modification of the energy-dispersive X-ray fluorescence method for the determination of metal elements in cement leachates - A chemometric approach
(Journal of the Serbian Chemical Society, 2020)
A modification of an analytical procedure for the energy-dispersive X-ray fluorescence (EDXRF) quantification of ten chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn) in the leachates obtained from cement binders ...
Optimization of spray drying conditions for production of Achillea millefolium extract powder
(Hemijska industrija, 2021)
In this study, a spray drying process of yarrow (Achillea millefolium L.) liquid extracts was optimized by using the response surface methodology. The study aimed to determine the influence of temperature (120-195 degrees ...
