Influence of size distribution and field amplitude on specific loss power
(Journal of Applied Physics, 2015)
Herein we present the results of specific loss power (SLP) analysis of polydisperse water based ferrofluids, Fe3O4/PEG200 and Fe3O4/PEG6000, with average Fe3O4 particle size of 9 nm and 11 nm, respectively. Specific loss ...
Galactic Structures from Gravitational Radii
(Galaxies, 2018)
We demonstrate that the existence of a Noether symmetry in f (R) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales. ...
Large polarons in dry DNA: temperature and anharmonic effects
(EPJ Web of Conferences, 2012)
We study the influence of temperature on large polarons in DNA molecules. Employing the mean field approximation we derive the slight generalization of the SSH Hamiltonian with temperature dependent parameters. It was found ...
Graphene/MoS2 heterostructures as templates for growing two-dimensional metals: Predictions from ab initio calculations
(Physical Review Materials, 2017)
Preparation of single-atom-thick layers of ordinary metals has been a challenging task since their closely packed atoms lack layered structure with highly anisotropic bonding. Using computational modeling based on density ...
The influence of the interchain coupling on large acoustic polarons in coupled molecular chains: Three coplanar parallel molecular chains
(Chaos, Solitons and Fractals, 2015)
We study the properties of the single large adiabatic polaron in the substances composed of three parallel equally separated coplanar molecular chains. Particular attention has been devoted to the influence of the interchain ...
Self-induced transparency of the optical phonons
(Chaos, Solitons and Fractals, 2017)
We show that the self-induced transparency of optical phonons may appear in a systems consisting of a two level atoms interacting with elastic waves. The presence of the gap in phonon spectrum substantially enhances the ...
Addressing the missing matter problem in galaxies through a new fundamental gravitational radius
(Journal of Cosmology and Astroparticle Physics, 2017)
We demonstrate that the existence of a Noether symmetry in f theories of gravity gives rise to a further gravitational radius, besides tile standard Schwarzschild one, determining the dynamics at galactic scales. By this ...
Devils staircase and the absence of chaos in the dc- and ac-driven overdamped Frenkel-Kontorova model
(Physical Review E, 2017)
The devils staircase structure arising from the complete mode locking of an entirely nonchaotic system, the overdamped dc+ac driven Frenkel-Kontorova model with deformable substrate potential, was observed. Even though no ...
Analytical modeling of electron energy loss spectroscopy of graphene: Ab initio study versus extended hydrodynamic model
(Ultramicroscopy, 2018)
We present an analytical modeling of the electron energy loss (EEL) spectroscopy data for free-standing graphene obtained by scanning transmission electron microscope. The probability density for energy loss of fast electrons ...
Crystal structures, magnetic properties and DFT study of cobalt(II) azido complexes with the condensation product of 2-quinolinecarboxaldehyde and Girards T reagent
(Polyhedron, 2018)
A tridentate NNO condensation product of 2-quinolinecarboxaldehyde and Girards T reagent (HLC1) in the presence of azide ions coordinates with cobalt(II) giving mononuclear azido Co(II) complex [CoHL (N-3)(3)](1) as a main ...
