(1993)The relations between the atomic softness and the atomic electric dipole polarizability are studied, both in a theoretical and an empirical way. For atoms and ions with one or two valence electrons a remarkably good ...
-
(2009)We investigate theoretically the existence of bulk and surface discrete breathers in a one-dimensional magnetic metamaterial comprised of a periodic binary array of split-ring resonators; the two types of resonators used ...
-
(2007)Ferroelectric liquid crystals bearing a chiral pyrrolidine-type ring were prepared using (-)-(S)-malic acid as a building block. The compounds were characterized using the thermal analysis techniques of DSC and POM, ...

(2003)BiKP2S6, monoclinic, P121 1 (No. 4), a = 6.6200(6) Å, b = 7.4058(7) Å. c = 9.9002(9) Å, β = 92.108(1)°, V = 485.0 Å3, Z = 2. Rgt(F) = 0.027,wRref(F2) = 0.060, T= 293 K. © 2014, Oldenbourg Wissenschaftsverlag GmbH, Rosenheimer ...
-
(IOP Publishing, 1996)We study propagation of excitations in one-dimensional tight-binding chains doped with random impurities that are classical Einstein oscillators. We find that the presence of impurities does not affect substantially the ...
-
(1975)A solvent and/or environmental effect has been introduced into the MO CNDO/2 calculation of a model hydrogen bonded system. Proton potential curves, potential energy, dipole moments, the polarizability component parallel ...
-
(2005)Two new homologous series of chiral esters derived from Schiff's bases containing a 1,3,4-thiadiazole unit (series 6 and 7) were synthesized and their liquid crystalline and ferroelectric properties investigated. All the ...
-
(Wiley, 1985)The introduction of local dielectric effects within the SCF theory of continuum solvent effects representation is examined at a semiempirical level. The formalism is developed in the frame of the reaction field theory ...
-
(American Physical Society, 2017)We explore the Floquet band structure and electronic transport in laser-illuminated bilayer graphene ribbons. By using a bias voltage perpendicular to the graphene bilayer we show how to get one-way charge and valley ...
-
(1985)We have analyzed the dependence of the serotonin receptor binding affinity on the electronic and steric reactivity indexes for a group of 5‐substituted tryptamines. The approaches employed are a new nonempirical Quantitative ...
-
(1997)An analytic solution for the Heisenberg Hamiltonian with arbitrarily long-range, ferromagnetic and/or antiferromagnetic, interactions on a Bethe lattice is obtained in the semiclassical approximation (S→∞). The density of ...
-
(American Chemical Society, 2018)In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on Ce-III and containing Co-II or Cu-II cations, assembled by the bifunctional ligand 1H-imidazole-4 ...
-
(American Institute of Physics Inc., 2018)An MHD shell model is used to describe the dissipative events that take place in magnetized plasmas. We analyze the activity of the time series of the magnetic energy dissipation rate obtained in the MHD shell model, which ...
-
(2000)We use the discrete nonlinear Schrödinger (DNLS) equation to show that nonlinear tight-binding lattices of different geometries and dimensionalities display a universal self-trapping behavior. First, we consider the problem ...
