Virtual water quality monitoring at inactive monitoring sites using Monte Carlo optimized artificial neural networks: A case study of Danube River (Serbia)
(Elsevier Science Bv, Amsterdam, 2019)
Rationalization of water quality monitoring stations nowadays is applied in many countries. In some cases, missing data from abandoned/inactive stations, spatial and temporal, could be very important, hence the use of ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Ltd, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Emerging contaminants in sediment core from the Iron Gate I Reservoir on the Danube River
(Elsevier, Amsterdam, 2019)
The Iron Gate I Reservoir is the largest impoundment on the Danube River. It retains gt 50% of the incoming total suspended solids load and the associated organic contaminants. In the sediment core of the Iron Gate I ...
UV protection afforded by textile fabrics made of natural and regenerated cellulose fibres
(Elsevier Sci Ltd, Oxford, 2019)
In the last decades the media have highlighted the ozone depletion as major environmental problem resulting in an increase in ultraviolet radiation (UVR) reaching the earth's surface. Besides the beneficial effects of human ...
Viscoelasticity of multicellular systems: From subcellular to supracellular levels
(Academic Press Ltd- Elsevier Science Ltd, London, 2019)
Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
Antibacterial ability of immobilized silver nanoparticles in agar-agar films co-doped with magnesium ions
(Elsevier Sci Ltd, Oxford, 2019)
The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components ...
Synthesis and thermal properties of arylazo pyridone dyes
(Elsevier Sci Ltd, Oxford, 2019)
Thermal degradation properties of 5-(4-substitutedphenylazo)-3-amido-6-hydroxy-4-methy1-2-pyridones and 5-(4-substitutedphenylazo)-3-cyano-6-hydroxy-4-methy1-2-pyridones dyes, differing in electron withdrawing and electron ...
Assembling Mesoscale-Structured Organic Interfaces in Perovskite Photovoltaics
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
Mesoscale-structured materials offer broad opportunities in extremely diverse applications owing to their high surface areas, tunable surface energy, and large pore volume. These benefits may improve the performance of ...
