Structural evidence of charge renormalization in semi-dilute solutions of highly charged polyelectrolytesThe European Physical Journal B - - 1999
W. Essafi, F. Lafuma, C.E. Williams
We show experimentally that Manning counterion condensation also leads to a
renormalization of the charge density at high concentrations of highly charged,
flexible, hydrophilic polyelectrolytes. Investigations by small angle neutron
and X-ray scattering of semi-dilute solutions of
poly(acrylamide-co-sodium-2-acrylamido-2-methylpropane sulfonate) at different
charge densities above the condensatio... hiện toàn bộ
Navier-Stokes-like equations applicable to adaptive cruise control traffic flowsThe European Physical Journal B - Tập 61 - Trang 363-370 - 2008
Y. G. Liu, Z. S. You, J. L. Zhou
Under the scenario in which, within a traffic flow, each vehicle is controlled
by adaptive cruise control (ACC), and the macroscopic one-vehicle probability
distribution function fits the Paveri-Fontana hypothesis, a set of reduced
Paveri-Fontana equations considering the ACC effect is derived. With the set, by
maximizing the specially defined informational entropy deviating from a certain
referen... hiện toàn bộ
Modulating coherence resonance in non-excitable systems by time-delayed feedbackThe European Physical Journal B - Tập 87 - Trang 1-13 - 2014
Paul M. Geffert, Anna Zakharova, Andrea Vüllings, Wolfram Just, Eckehard Schöll
We propose a paradigmatic model system, a subcritical Hopf normal form subjected
to noise and time-delayed feedback, to investigate the impact of time delay on
coherence resonance in non-excitable systems. We develop analytical tools to
estimate the stationary distribution and the time correlations in nonlinear
stochastic delay differential equations. These tools are applied to our model to

Low-energy electron transmission in a partially unzipped zigzag nanotubeThe European Physical Journal B - Tập 77 - Trang 433-440 - 2010
Yu. O. Klymenko
Based on the nearest-neighbor tight-binding approximation, we present exact
analytical expressions for electron transmission in nanotube/ribbon junctions,
generated by incomplete unzipping of zigzag nanotubes. By assuming
one-dimer-line difference in the widths of the leads, it is demonstrated that
such a contact exhibits zero backscattering of low-energy electrons entering
from the graphene side ... hiện toàn bộ
Preparation and characterization of cobalt-based nanostructured materialsThe European Physical Journal B - Tập 31 - Trang 545-551 - 2003
G. Carotenuto, L. Pasquini, E. Milella, M. Pentimalli, R. Lamanna, L. Nicolais
Nano-sized cobalt clusters passivated by alkane-thiol molecules were obtained by
the action of concentrated thiol solutions on micrometric cobalt particles.
Thiol molecules caused an erosive process on the metal grains with the
consequent formation of nano-sized metal debris and cobalt thiolate as
by-product. The final material microstructure was composed by cobalt clusters
embedded into a continu... hiện toàn bộ
Electron transport in bulk n-doped 3C-SiC by using a non-equilibrium quantum kinetic theoryThe European Physical Journal B - Tập 92 - Trang 1-6 - 2019
Amanda M. D. Corrêa, Clóves G. Rodrigues, Roberto Luzzi
In this paper we present a study on the charge transport in bulk n-type doped
semiconductor 3C-SiC (in both, transient and steady state) using a
non-equilibrium quantum kinetic theory derived from the method of nonequilibrium
statistical operator (NSO), which furnishes a clear description of the
irreversible phenomena that occur in the evolution of the analyzed system. We
obtain theoretically the ... hiện toàn bộ
Magnetic properties of dc magnetron sputtered and evaporated amorphous filmsThe European Physical Journal B - - 2002
H. Kockar, T. Meydan
Compositions of Fe81B13.5Si3.5C2, Fe67Co18Si1B14 and Fe5.85Co72.15Mo2B15Si5 were
deposited on to rigid and flexible substrates for the first time using a dc
sputtering source as part of a novel Rotating Cryostat (RC). The films sputtered
on silicon and glass show only isotropic magnetisation, whereas those sputtered
on a polyimide (KaptonTM) substrate exhibited either isotropic or anisotropic
magn... hiện toàn bộ
Quench dynamics and defects formation in the Ising chain in a transverse magnetic fieldThe European Physical Journal B - Tập 95 - Trang 1-13 - 2022
Alexander I. Nesterov, Mónica F. Ramírez, Sergey G. Ovchinnikov
We study quench dynamics and defects formation in the one-dimensional quantum
Ising chain in a time-dependent transverse magnetic field, given by a
semi-infinite pulse and as the pulse of the finite width. The system’s final
state depends on the quench time and pulse amplitude, resulting in the emergence
of topological defects, and consists of a mixture of ground and excited states.
We obtain a ne... hiện toàn bộ
