Synthesis, characterization, and growth simulations of Cu?Pt bimetallic nanoclusters
(Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2014-08)
Highly monodispersed Cu–Pt bimetallic nanoclusters were synthesized by a facile synthesis approach. Analysis of transmission electron microscopy (TEM) and spherical aberration (Cs)-corrected scanning transmission electron ...
Gold-palladium core@shell nanoalloys: Experiments and simulations
(Royal Society of Chemistry, 2015-02)
In this work, we report a facile synthesis route, structural characterization, and full atomistic simulations of gold-palladium nanoalloys. Through aberration corrected-STEM, UV-vis spectroscopy and EDS chemical analysis, ...
Nonequilibrium Dynamics of the Chiral Quark Condensate under a Strong Magnetic Field
(Mdpi, 2021-04-01)
Strong magnetic fields impact quantum-chromodynamics (QCD) properties in several situations; examples include the early universe, magnetars, and heavy-ion collisions. These examples share a common trait-time evolution. A ...
Stochastic dynamics of collective modes for Brownian dipoles
(American Physical Society, 2015-03)
The individual motion of a colloidal particle is described by an overdamped Langevin equation. When rotational degrees of freedom are relevant, these are described by a corresponding Langevin process. Our purpose is to ...
Ecuaciones de langevin en coordenadas polares
(Medellín - Ciencias - Maestría en Ciencias - Matemática AplicadaEscuela de matemáticasUniversidad Nacional de Colombia - Sede Medellín, 2019-08-16)
In the first part of this work we use Levy's characterization of Brownian motion and a Time-Change theorem for Martingales to deduce the stochastic differential equations that describe the radial and angular processes of ...
Understanding the Lévy Ratchets in Terms of Lévy Jumps
(Iop Publishing, 2013-02)
We investigate the overdamped dynamics of a particle in a spatially periodic potential with broken reflection symmetry and subject to the action of a symmetric white Lévy noise. The system (referred to as the Lévy ratchet) ...
Joint probability distributions and fluctuation theorems
(IOP Publishing, 2012-02)
We derive various exact results for Markovian systems that spontaneously relax to a non-equilibrium steady-state by using joint probability distributions symmetries of different entropy production decompositions. The ...
Encapsulation of paclitaxel into a bio-nanocomposite. a study combining inelastic neutron scattering to thermal analysis and infrared spectroscopy
(E D P Sciences, 2015-01-01)
The anticancer drug paclitaxel was encapsulated into a bio-nanocomposite formed by magnetic nanoparticles, chitosan and apatite. The aim of this drug carrier is to provide a new perspective against breast cancer. The ...
Surface effects on vortex dynamics in thin type-II superconducting stripes with random pinning
(Elsevier B.V., 2004-08-01)
We analyze the dynamics of a driven vortex lattice moving in a thin Superconducting stripe. The two dimensional stripe is assumed to be finite in the longitudinal direction, where we take into account the Surface effects, ...
