One‐Pot Synthesis of Carbon‐Supported Pd Nanoparticles with Ni and Carbon Matrix Protection for Durable Alkaline Hydrogen Oxidation Reaction

open access: yesChemCatChem, Volume 16, Issue 15, August 12, 2024.
The class of electrocatalyst with protected metal active sites (e. g. the present carbon‐capped and carbon‐supported nanoparticles) is not new in the literature and is being applied in many domains of electrochemistry, due to the peculiar properties of such materials, like high tolerance towards passivation, hydridation or degradation (e. g.

Procedimiento analitico para la determinacion de Ti e Impurezas en ceramica piezoelectrica de BaTiO 3.

open access: yesRevista CENIC Ciencias Químicas, 2003
El control del contenido de Ti e impurezas en las ceramicas piezoelectricas es muy importante dado que influyen fuertemente en las propiedades electricas y electromecanicas de las mismas . Por ejemplo, si una ceramica piezoelectrica se somete a on fuerte
