Chemical composition, antioxidant and antimicrobial activity of Thymus praecox supercritical extracts
(Elsevier Science Bv, Amsterdam, 2016)
The chemical composition, antimicrobial and antioxidant activity of Thymus praecox extracts obtained by fractional supercritical fluid extraction (SFE) with carbon dioxide were investigated. Properties of supercritical ...
Immobilization of Candida antarctica lipase B on kaolin and its application in synthesis of lipophilic antioxidants
(Elsevier Science Bv, Amsterdam, 2017)
Lipase B from Candida antarctica was immobilized by adsorption onto laboratory prepared metakaolin. This support has great potential for enzyme immobilization since it has good mechanical characteristics and thermal stability ...
Review: The approaches for estimation of limit of detection for ICP-MS trace analysis of arsenic
(Talanta, 2012)
The analytical properties of an analytical method must be evaluated through validation protocols. Beside specificity and/or selectivity, linearity of calibration, repeatability and accuracy, the most important parameters ...
Dual responsive antibacterial Ag-poly(N-isopropylacrylamide/itaconic acid) hydrogel nanocomposites synthesized by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation ...
Experimental and modelling study on strontium removal from aqueous solutions by Lagenaria vulgaris biosorbent
(Elsevier Science Bv, Amsterdam, 2018)
The shell of Lagenaria vulgaris (LV) plant was used as biosorbent for strontium removal from aqueous solutions. Chemical structure of the biosorbent's surface was characterized by the means of FTIR and Boehm's titrations. ...
Artificial neural network modelling of biological oxygen demand in rivers at the national level with input selection based on Monte Carlo simulations
(Springer Heidelberg, Heidelberg, 2015)
Biological oxygen demand (BOD) is the most significant water quality parameter and indicates water pollution with respect to the present biodegradable organic matter content. European countries are therefore obliged to ...
Photoelectochemical behavior of TiO2-NT's modified with SILAR deposited iron oxide
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
The fast reaction of forced hydrolysis of iron(111) nitrate in hypochlorite solution at room temperature, leads to the formation of mainly hematite, alpha-Fe203. Successive ion adsorption and reaction (SILAR) is applied ...
Mass transfer and concentration boundary layer in a particulate fluidized bed
(Elsevier Science Bv, Amsterdam, 2016)
The aim of this study was to analyze the concentration boundary layer for a comprehensive description of the mass transfer in systems with fluidized particles. Mass transfer from the wall of the column to the fluid in the ...
Reactor conceptual design by optimization for hydrogen production through intensified sorption- and membrane-enhanced water-gas shift reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In this feasibility study, a novel industrial-scale reactor structure for continuous hydrogen production via intensified water-gas shift (WGS) reaction is proposed. It considers both trickling calcium-oxide sorbent for ...
Opportunities for intensification of Fischer-Tropsch synthesis through reduced formation of methane over cobalt catalysts in microreactors
(Royal Soc Chemistry, Cambridge, 2015)
Due to the global growth in production of synthetic fuels via the Gas-to-Liquid (GTL), Coal-To-Liquid (CTL) and Biomass-To-Liquid (BTL) processes, academic and industrial interest in Fischer-Tropsch synthesis (FTS) research ...
