Dispersion effect in formic acid oxidation on PtAu/C nanocatalyst prepared by water-in-oil microemulsion method
(Elsevier Science Bv, Amsterdam, 2019)
Low loading PtAu nanoparticles supported on high area carbon were synthesized by water-in-oil microemulsion method and examined for formic acid and methanol oxidation. Prepared catalyst powder was characterized by Xray ...
Impact resistant hybrid composites reinforced with inorganic nanoparticles and nanotubes of WS2
(Elsevier Sci Ltd, Oxford, 2019)
Impact resistant nanocomposites are recognized as promising in saving lives in the car, skiing and bicycle accidents, preventing the failure of polymer-based prostheses and orthotic devices, as well as for various defense ...
Urban population exposure to tropospheric ozone: A multi-country forecasting of SOMO35 using artificial neural networks
(Elsevier Sci Ltd, Oxford, 2019)
Urban population exposure to tropospheric ozone is a serious health concern in Europe countries. Although there are insufficient evidence to derive a level below which ozone has no effect on mortality WHO (World Health ...
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 ...
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 ...
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 ...
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 ...
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 ...
