Influence of surface coverage of kaolin with surfactant ions on adsorption of ochratoxin A and zearalenone
(Elsevier, 2021)
A natural kaolin from Serbia was modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) - (25, 50 and 90% of kaolin cation exchange capacity). Samples were denoted as OKR-25, OKR-50 and OKR-90. Several ...
Analysis and experimental demonstration of forced periodic operation of an adiabatic stirred tank reactor: Simultaneous modulation of inlet concentration and total flow-rate
(Elsevier, 2021)
It is well known, that forced periodic operation possesses the potential for process improvements. Nevertheless, only a small number of applications is reported, due to complex realization, limited predictability and high ...
Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Elsevier, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using α,ω-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Content and distribution of major and trace elements as a tool to assess the genotypes, harvesting time, and cultivation systems of potato
(Elsevier, 2021)
The effects of organic versus integral and conventional crop management on content and distribution of major and trace elements in different varieties of potato were investigated in a three year field trial. A set of 48 ...
Effect of mesoporous silica nanoparticles on the properties of polyurethane network composites
(Elsevier, 2021)
Novel polyurethane nanocomposite (PUN) materials containing different surface-functionalized mesoporous silica nanoparticles (MSNs) were prepared by in situ polymerization methodology. Polyurethane network was formed from ...
SR-FTIR spectro-microscopic interaction study of biochemical changes in HeLa cells induced by Levan-C60, Pullulan-C60, and their cholesterol-derivatives
(Elsevier, 2020)
Abstract
Objects of the present study are improved fullerene C60 drug carrier properties trough encapsulation by microbial polysaccharides, levan (LEV), pullulan (PUL), and their hydrophobized cholesterol-derivatives (CHL ...
Study on the assessment of humification processes during biodegradation of heavy residual fuel oil
(Elsevier, 2021)
The aim of this study was to investigate the creation of humic substances during biodegradation of heavy residual fuel oil, because there are indications that substances similar to humic substances are generated during ...
Geochemical characterization of sediments from the archaeological site Vinča – Belo Brdo, Serbia
(Elsevier, 2021)
In this study, a multidisciplinary approach was used for a detailed characterization of sediments from the archaeological site Vinča – Belo Brdo, Serbia, one of the most important Neolithic settlements in Europe. This ...
Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Elsevier, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
Relating environmental pressures to littoral biological water quality indicators in Western Balkan lakes: Can we fill the largest gaps?
(Elsevier, 2022)
Along six transects in each of six lakes across the Western Balkans, we collected data for three groups of littoral biological water quality indicators: epilithic diatoms, macrophytes, and benthic invertebrates. We assessed ...
