Can volcanic dust suspended from surface soil and deserts of Iceland be transferred to central Balkan similarly to African dust (Sahara)?
(Switzerland : Frontiers Media S.A., 2019)
In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. ...
The role of spin states in the catalytic mechanism of the intra- and extradiol cleavage of catechols by O-2
(Royal Soc Chemistry, Cambridge, 2017)
Iron-dependent enzymes and biomimetic iron complexes can catalyze the ring cleavage of very inert, aromatic compounds. The mechanisms of these transformations and the factors that lead either to extradiol cleavage or ...
Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions
(Elsevier, 2019)
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon carbon cloth. The effects of different milling atmospheres, in the air and inert conditions, were investigated. Changes in kind ...
Visualisation of the interaction between Acidithiobacillus ferrooxidans and oil shale by atomic force microscopy
(Technical Faculty, Bor-Serbia, Bor, 2012)
This study visually documents the mechanical contact and interaction between the bacterial cells of two biogeocenotically different strains of Acidithiobacillus ferrooxidans (At. ferrooxidans) and oil shale containing ...
Spin- and valley-polarized transport in a monolayer of MoS2
(Amer Physical Soc, College Pk, 2016)
We investigate dc and ac transport in a monolayer of MoS2 in the presence of an effective mass asymmetry, a momentum-dependent term, and an out-of plane or in-plane Zeeman term. Analytical results are presented for both ...
Remote electron plasmon polaron in graphene
(Amer Physical Soc, College Pk, 2012)
The Coulomb interaction and the correlation of a remote electron with a single layer of graphene is investigated in the presence of a magnetic field applied perpendicular to the graphene layer. The remote electron polarizes ...
Tunable invisibility cloaking by using isolated graphene-coated nanowires and dimers
(England : Nature Publishing Group, 2017)
We investigate, both theoretically and numerically, a graphene-coated nano-cylinder illuminated by a plane electromagnetic wave in the far-infrared range of frequencies. We have derived an analytical formula that enables ...
Magnetic and electric control of spin- and valley-polarized transport across tunnel junctions on monolayer WSe2
(Amer Physical Soc, College Pk, 2017)
The recent experimental realization of high-quality WSe2 leads to the possibility of an efficient manipulation of its spin and valley degrees of freedom. Its electronic properties comprise a huge spin-orbit coupling, a ...
Heteropentanuclear Oxalato-Bridged nd-4f (n=4, 5) Metal Complexes with NO Ligand: Synthesis, Crystal Structures, Aqueous Stability and Antiproliferative Activity
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
A series of heteropentanuclear oxalate-bridged Ru(NO)-Ln (4d-4f) metal complexes of the general formula (nBu(4)N)(5)[Ln{RuCl3(-ox)(NO)}(4)], where Ln=Y (2), Gd (3), Tb (4), Dy (5) and ox=oxalate anion, were obtained by ...
Electrically controlled dc and ac transport in bilayer WSe2
(American Physical Society (APS), 2018)
We investigate quantum transport in a bilayer WSe2 in the presence of an external potential V and interlayer coupling. The dc and ac conductivities are evaluated in the framework of linear response theory. As functions of ...
