Caracterização eletroquímica do eletrólito sólido NASICON Li1,5Al0,5Ge1,5(PO4)3 (LAGP)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2021-08-17)
Solutions to the environmental and social challenges of postmodern society converge on a common point: sustainability. Doing more with less and using environmentally friendly materials is imperative. Energy storage is ...
Time-Retrenched Synthesis of BaTaO2N by Localizing an NH3 Delivery System for Visible-Light-Driven Photoelectrochemical Water Oxidation at Neutral pH: Solid-State Reaction or Flux Method?
(American Chemical Society, 2021-09)
Among 600 nm class transition-metal oxynitrides, BaTaO2N with a cubic Pm3¯ m perovskite-type structure is promising for solar water oxidation due to its absorption of visible light up to 660 nm, narrower band gap (Eg = 1.9 ...
Enhanced stability in CO2 of Ta doped BaCe0.9Y 0.1O3-δ electrolyte for intermediate temperature SOFCs
(2013-04-01)
The influence of Ta concentration on the stability of BaCe 0.9-xTaxY0.1O3-δ (where x=0.01, 0.03 and 0.05) powders and sintered samples in CO2, their microstructure and electrical properties were investigated. The ceramic ...
