Controlling domain wall chirality by combining hard and soft magnetic materials in planar nanostructures with wire-ring morphology
(Elsevier B.V., 2021-01)
Vortex domain walls (DWs) are characterized by their chirality, an important property that needs to be controlled for the use of such walls in potential technological applications. In this work we explore a wire-ring ...
Properties of the hard-sphere fluid at a planar wall using virial series and molecular-dynamics simulation
(American Institute of Physics, 2018-07)
We study the hard-sphere fluid in contact with a planar hard wall. By combining the inhomogeneous virial series with simulation results, we achieve a new benchmark of accuracy for the calculation of surface thermodynamics ...
Virial series for inhomogeneous fluids applied to the Lennard-Jones wall-fluid surface tension at planar and curved walls
(American Institute of Physics, 2016-05)
We formulate a straightforward scheme of statistical mechanics for inhomogeneous systems that includes the virial series in powers of the activity for the grand free energy and density distributions. There, cluster integrals ...
Steady quasi-homogeneous granular gas state
(2005)
Using Newtonian molecular dynamics we study a gas of inelastic hard disks subject to shear between two planar parallel thermal walls. The system behaves like a Couette flow and it is tuned to produce a steady state that ...
Mapping experimental and theoretical reactivity descriptors of fe macrocyclic complexes deposited on graphite or on multi walled carbon nanotubes for the oxidation of thiols: Thioglycolic acid oxidation
(2021)
We have studied the electro-oxidation of thioglycolic acid (TGA) catalyzed by iron phthalocyanines and iron porphyrins (FeN4 complexes) deposited on ordinary pyrolytic graphite and on multiwalled carbon nanotubes. The ...
Steady quasi-homogeneous granular gas state
(ELSEVIER SCIENCE BV, 2005-10-01)
Using Newtonian molecular dynamics we study a gas of inelastic hard disks subject,to shear between two planar parallel thermal walls. The system behaves like a Couette flow and it is tuned to produce a steady state that ...
Bending and Gaussian rigidities of confined soft spheres from second-order virial series
(American Physical Society, 2016-08)
We use virial series to study the equilibrium properties of confined soft-spheres fluids interacting through the inverse-power potentials. The confinement is induced by hard walls with planar, spherical, and cylindrical ...
Dynamics of confined liquid crystals
(Medellín - Minas - Doctorado en Ingeniería - Ciencia y Tecnología de MaterialesDepartamento de Materiales y MineralesUniversidad Nacional de Colombia - Sede Medellín, 2020-09-07)
Thermotropic nematic liquid crystals in contact with surfaces at the nanoscale were studied by means of beyond equilibrium thermodynamics and computational simulations. In particular, nanoparticles of different geometries ...
Optimization of X-ray tube voltage to improve the precision of two phase flow meters used in petroleum industry
