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 ...
Fischer-Tropsch synthesis product selectivity over an industrial iron-based catalyst: Effect of process conditions
(Elsevier Science Bv, Amsterdam, 2016)
The effect of process conditions on product selectivity of Fischer-Tropsch synthesis (FTS) over industrial iron-based catalyst (100 Fe/5 Cu/4.2 K/25 SiO2) was studied in a 1-L stirred tank slurry reactor. Experiments were ...
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 ...
Calcium-Alginate-Inulin Microbeads as Carriers for Aqueous Carqueja Extract
(Wiley, Hoboken, 2016)
Carqueja (Pterospartum tridentatum) is an endemic species and various bioactive compounds have been identified in its aqueous extract. The aim of this study was to protect the natural antioxidants from the aqueous extract ...
Solvatochromism of N-aryl-phenylacetamides / Solvatohromizam N-aril-fenilacetamida
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Amide derivates are biologically active compounds and they are widely used in all spheres of life. Therefore, it is very important to know their physical-chemical properties. In this work the influence of characteristics ...
Effect of LCF on behavior and microstructure of microalloyed HSLA steel and its simulated CGHAZ
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Numerous structural components made of high strength low-alloyed steels are often exposed to low-cycle fatigue loading during their exploitation life. In order to study the fatigue behavior of one grade of structural steels ...
Electrochemical stability of metformin in NaHCO3 and Na2SO4 water solution at Au, GC and IrOx electrodes
(Srpsko hemijsko društvo, Beograd, 2019)
In this study the electrochemical behavior of metformin (MET), oral antihyperglycaemic agent, was assayed at three different electrodes. The drug standard was investigated by cyclic voltammetry and square wave voltammetry ...
The effect of K2O on the crystallization of niobium germanate glasses
(International Institute for the Science of Sintering, Beograd, 2011)
The effect of K2O content on the crystallization of niobium germanate glasses with 22.7- 24.27 wt% of GeO2 and 54.59-57.48 wt% of Nb2O5 was examined. The glasses crystallize by primary crystallization and the formed ...
Single step recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction
(Taylor & Francis Inc, Philadelphia, 2016)
Recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction was studied with maximal possible crude enzyme loads. In polyethylene glycol/dextran and polyethylene glycol/salt systems the influences of ...
Development of the automated software and device for determination of wicking in textiles using open-source tools
(Public Library Science, San Francisco, 2020)
The development of automated software and the device for determination of wicking of textile materials, using open-source ImageJ libraries for image processing, and newly designed additional algorithm for the determination ...
