Electrochemical oxidation of ethanol on palladium-nickel nanocatalyst in alkaline media
(Elsevier, Amsterdam, 2016)
Pd-Ni/C catalyst was synthesized employing a borohydride reduction method. The high area Ni was first dispersed on the carbon support and then modified by Pd nanoparticles. Transmission electron microscopy confirmed ...
RuxTi1-xO2 as the support for Pt nanoparticles: Electrocatalysis of methanol oxidation
(Amsterdam : Elsevier, 2015)
Two binary Ru-Ti oxides, Rum Ti0.9O2 and Ru0.7Ti0.3O2, were synthesized by the sol-gel method and used as an electrocatalyst support. The system was characterized by XRD, EDS, TEM and cyclic voltammetry. The Rum Ti0.9O2 ...
Susceptibility of European freshwater fish to climate change: Species profiling based on life-history and environmental characteristics
(Wiley, Hoboken, 2019)
Climate change is expected to strongly affect freshwater fish communities. Combined with other anthropogenic drivers, the impacts may alter species spatio-temporal distributions and contribute to population declines and ...
Magnetism and Antiferroelectricity in MgB6
(Amer Physical Soc, College Pk, 2012)
We report on a density functional theory study demonstrating the coexistence of weak ferromagnetism and antiferroelectricity in boron-deficient MgB6. A boron vacancy produces an almost one dimensional extended molecular ...
Humidity sensing properties of nanocrystalline pseudobrookite (Fe2TiO5) based thick films
(Elsevier, 2018)
Pseudobrookite based nanopowder was obtained by solid state synthesis of starting hematite and anatase nanopowders in the weight ratio 55:45. Structural and morphological properties were analyzed using X-ray diffraction ...
Mechanical and microstructural properties of alkali-activated fly ash geopolymers
(Elsevier, Amsterdam, 2010)
This paper investigates the properties of geopolymer obtained by alkali-activation of fly ash (FA), i.e. the influence of characteristics of the representative group of FA (class F) from Serbia, as well as that of the ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
Phenolic profile, chromatic parameters and fluorescence of different woods used in Balkan cooperage
(Elsevier Science Bv, Amsterdam, 2019)
The aim of this research was to study phenolic compounds of diverse botanical species of wood commonly used in cooperage in Balkan countries. Several botanical species have been considered including mulberry (Morns alba ...
Phosphorus deficiency is the major limiting factor for wheat on alluvium polluted by the copper mine pyrite tailings: a black box approach
(Springer, Dordrecht, 2011)
Failures of tailings dams have degraded large areas of agricultural alluvial soils worldwide, and concomitant soil pollution studies are abundant. Yet, the data on the actual effects of thereby imposed stresses on major ...
Effects of the concentrated NH4NO3 solution on mechanical properties and structure of the fly ash based geopolymers
(Elsevier Sci Ltd, Oxford, 2013)
The geopolymers based on fly ash were exposed to the concentrated (6 M) NH4NO3 solution for 540 days. The highest compressive strength decrease occurred in the initial 28 days testing period. Study of the effects of the ...
