Spin- and valley-polarized transport through ferromagnetic and antiferromagnetic barriers on monolayer MoS2
(Elsevier, 2016)
We study ballistic electron transport through single or double barriers on monolayer MoS2, of width d, in the presence of a ferromagnetic field Moran antiferromagnetic field F. The total conductance,gc, its spin-up and ...
Decarbonylative Dibromination of 5-Phenylthiophene-2-carbaldehyde with Bromine
(Georg Thieme Verlag Kg, Stuttgart, 2016)
The decarbonylative dibromination of 2-thiophenecarboxaldehyde derivatives with bromine under mild conditions is developed. The mechanism for the decarbonylation is investigated by experimental and instrumental techniques ...
Substituted naphthalenes: Stability, conformational flexibility and description of bonding based on ETS-NOCV method
(Elsevier, 2016)
For all dimethylnaphthalenes (DMNs) the transition from a planar ring conformation to a nonplanar one results in energy increase in the range 1.7-2.4 kcal/mol. There is a linear relationship between averaged rigidity ...
Pollution by Urticaceae pollen-influence of selected air pollutants and meteorological parameters
(Springer Heidelberg, Heidelberg, 2016)
The goal of this study was to analyze the influence of pollutants (concentrations of NO2, SO2, and soot in the air) and meteorological parameters (air temperature, humidity, wind speed, air pressure, cloud index) on ...
Nephrococcus serbicus, a new coccoid cyanobacterial species from Bozana Cave, Serbia
(Magnolia Press, Auckland, 2016)
During the investigation of cyanobacterial diversity in Bozana Cave, which is situated in a limestone region in western Serbia, a new species of cyanobacterium belonging to the genus Nephrococcus was found. So far, there ...
Comparison of single extraction procedures and the application of an index for the assessment of heavy metal bioavailability in river sediments
(Springer Heidelberg, Heidelberg, 2016)
Metals in sediments are present in different chemical forms which affect their ability to transfer. The objective of this body of work was to compare different extraction methods for the bioavailability evaluation of some ...
Complex bifurcations in the oscillatory reaction model
(Oxford : Pergamon-Elsevier Science Ltd, 2016)
The mixing of different types of bifurcations, i.e. supercritical Andronov-Hopf (SAH), double loop (DL) and saddle-loop (SL) bifurcations in the vicinity of their total annihilation, is examined on the highly nonlinear ...
Integrative approach of histopathology and histomorphometry of common carp (Cyprinus carpio L.) organs as a marker of general fish health state in pond culture
(Wiley, Hoboken, 2016)
The semi-intensive system of common carp mono-culture in earthen ponds is currently the most practiced fish rearing system in several countries in Eastern Europe. This system is based on the addition of supplemented feed ...
Electrochemical lithiation/delithiation kinetics and capacity of phosphate tungsten bronze and its chemically pre-lithiated derivatives in aqueous solutions
(Springer, 2016)
Monophosphate bronze (PW8O26, WPB) was synthesized by low-temperature (650 °C) heating of 12-tungstophosphoric acid (WPA). Its lithiated derivative with a low lithium content (Li3-WPB) was synthesized by heating lithium ...
Cross-linking of highly methoxylated pectin with copper: the specific anion influence
(Royal Soc Chemistry, Cambridge, 2016)
The aim of this work was to investigate the influence of specific anions on the cross-linking process of highly methoxylated pectin using the following copper salts CuSO4; Cu(C2H3O2)(2); CuCl2; and Cu(NO3)(2) wherein the ...
