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 ...
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 ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
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 ...
The alleviation of zinc toxicity by silicon is related to zinc transport and antioxidative reactions in rice
(Springer, Dordrecht, 2011)
The objective of this study is to elucidate the roles of silicon (Si) in enhancing tolerance to excess zinc (Zn) in two contrasting rice (Oryza sativa L.) cultivars: i.e. cv. TY-167 (Zn-resistant) and cv. FYY-326 (Zn-sensitive). ...
Positive influence of Sb doping on properties of di-phase multiferroics based on barium titanate and nickel ferrite
(Elsevier Science Sa, Lausanne, 2018)
Multiferroic composite materials based on antimony doped barium titanate/nickel ferrite were prepared by a mixing route. In order to obtain fine grained microstructure composite materials, pure constituent phases were ...
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 ...
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 ...
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 ...
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 ...
