Enlarged sheet of ZnS(en)0.5 hybrid semiconductors with photocatalytic activity
(2015)"Sheets of ZnS(en)0.5 hybrid semiconductors were prepared by the precipitation method in an ethylenediamine–water solution and it was enlarged by varying the aging at a long period time. The characterization of the hybrid ... -
Estudio del efecto elastocalórico en aleaciones con memoria de forma con distintas transformaciones de fase martensítica
(2021-11-18)"Una de las alternativas para economizar energía en la refrigeración comercial está relacionada con el uso de efectos calóricos en materiales sólidos. Este método no involucra el uso de gases que pueden afectar el medio ... -
Evolution of spherical cavitation bubbles: parametric and closed-form solutions
(2016)"We present an analysis of the Rayleigh-Plesset equation for a three dimensional vacuous bubble in water. In the simplest case when the effects of surface tension are neglected, the known parametric solutions for the radius ... -
Existence of periodic orbits in nonlinear oscillators of Emden-Fowler form
(2016)"The nonlinear pseudo-oscillator recently tackled by Gadella and Lara is mapped to an Emden-Fowler (EF) equation that is written as an autonomous two-dimensional ODE system for which we provide the phase-space analysis and ... -
Expanded use of a fast photography technique to characterize laser-induced plasma plumes
(2014-06)"Expanded use of fast photography is proposed to characterize laser ablation plasma plumes by the analysis of a set of photographs by means of appropriate mathematical algorithms. The laser ablation plasma plumes studied ... -
Extension of a factorization method of nonlinear second order ODE´s with variable coefficients
(2017)"The factorization of nonlinear second-order differential equations proposed by Rosu and Cornejo-Pérez in 2005 is extended to equations containing quadratic and cubic forms in the first derivative. A few illustrative ... -
Factorization method for some inhomogeneous Lienard equations
(Sociedad Mexicana de Física, A. C., 2021)"The factorization of inhomogeneous Li\'enard equations is performed showing that through the factorization conditions involved in the method one can obtain forcing terms for which closed-form solutions exist. Because of ... -
Factorization of the Riesz-Feller Fractional Quantum Harmonic Oscillators
(IOP Publishing, 2020)"Using the Riesz-Feller fractional derivative, we apply the factorization algorithm to the fractional quantum harmonic oscillator along the lines previously proposed by Olivar-Romero and Rosas-Ortiz, extending their results. ... -
Flexible rewritable organic memory devices using nitrogen-doped CNTs/PEDOT:PSS composites
(Elsevier, 2017)"Nonvolatile rewritable organic memory devices based on poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and nitrogen doped multi-walled carbon nanotube (NCNT) nanocomposites were fabricated on glass ... -
Frenet-Serret vacuum radiation, detection proposals and related topics
(2005)"The paradigmatic Unruh radiation is an ideal and simple case of stationary vacuum radiation patterns related to worldlines defined as Frenet-Serret curves. We review the corresponding body of literature as well as the ... -
Generalización paramétrica de la espiral de cornu en difracción óptica
(2016)"El objetivo general de este estudio fué realizar una revisión matemática detallada de las formulaciones básicas del fenómeno de difracción óptica. Es por ello que en el Capítulo 1 se presenta una descripción de diferentes ... -
Generalized Cornu-type spirals and their Darboux parametric deformations
(Elsevier, 2019)"We generalize the Fresnel integrals and introduce a class of spirals F-n, which contains the Cornu spiral as the case F-2. Their Darboux parametric deformations are also investigated. The F-3 spiral and some of its Darboux ... -
Generalizing segregation and chemical ordering in bimetallic nanoclusters through atomistic view points
(2009-10)"We predict general trends for surface segregation in binary metal clusters based on the difference between the atomic properties of the constituent elements. The energetically most favorable site for a guest atom on a ... -
