A functional assembly of SiO2 nanospheres/graphene oxide composites
(Elsevier, 2015)
"A novel assembly of SiO2 nanospheres functionalized on graphene oxide (GO) sheets was prepared by a one-step microwave-hydrothermal method. The nanocomposites were well characterized and investigated to study their Rhodamine ...
Síntesis y caracterización de óxidos cerámicos nanoestructurados de Ce y/o Mn para remoción de fluoruro del agua
(2015)
"El método solvotermal ha sido empleado con éxito en la preparación de materiales
cerámicos avanzados, por ejemplo de óxidos cerámicos. La intervención de
compuestos orgánicos en la síntesis de óxidos cerámicos a partir ...
Estudio de los efectos magnetocalórico y elastocalórico en aleaciones Heusler ferromagnéticas de los sistemas Ni-Mn-In-X (X= Cu, Cr y Ga)
(2016)
"Se fabricaron aleaciones tipo Heusler de los sistemas Ni-Mn-In-X (X= Cu, Cr y Ga) que presentan transformación martensítica en un intervalo de temperatura cercano a la temperatura ambiente. La síntesis de las aleaciones ...
Generalización paramétrica de la espiral de cornu en difracción óptica

"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 ...
Transformation behavior and inverse caloric effects in magnetic shape memory Ni44-xCuxCo6Mn39Sn11 ribbons
(2017-10)
"An influence of the Cu doping on structural, magnetic and thermoelastic properties of the Heusler Ni44-xCuxCo6Mn39Sn11 (x = 1–4 at%) ribbons has been investigated. It is found that the addition of Cu stabilizes austenite ...
Large and reversible elastocaloric effect near room temperature in a Ga-doped Ni–Mn–In metamagnetic shape-memory alloy
(2017-02)
"We report a giant elastocaloric effect near room temperature in a polycrystalline Ga-doped Ni-Mn-In ferromagnetic shape-memory alloy. The elastocaloric effect has been quantified by measuring both isothermal stress-induced ...
Electrochemical and mechanical behavior in polycrystalline CoNi-Ga shape memory alloys
(2014)
"Electrochemical behavior and microstructure was studied in polycrystalline Co38.3Ni32.1Ga29.6 alloy using the electrochemical technique of polarization curves in a medium of 3.5 wt % NaCl and 0.5M H2SO4. The importance ...
Analysis of Ostwald ripening in Ni-rich Ni–Ti alloys by diffusion couples
(2014)
"The coarsening kinetics of gamma' precipitates in Ni-rich Ni-Ti alloys are studied using a Ni-11-5 wt% Ti and pure Ni diffusion couple. The formed concentration gradient allowed to study the aging process at 1023 K (750 ...
Enhanced refrigerant capacity and magnetic entropy flattening using a two-amorphous FeZrB(Cu) composite
(2011-12)
"The temperature dependence of the isothermal magnetic entropy change, Delta S-M, and the magnetic field dependence of the refrigerant capacity, RC, have been investigated in a composite system xA + (1 - x) B, based on ...
Hybridization vs. bond stretching isomerism in Ru(II) cyclometalated complexes of 2-phenylpyridine
(MDPI, 2012-01)
"The phenomenon of formation of two isomers, yellow and orange, of the cyclometalated Ru(II) complex, [Ru(o-C6H4-py)(MeCN)4]+, was investigated by EELS spectroscopy and theoretical calculations. Both forms show very similar ...
