Nature of the "Z"-phase in layered Na-ion battery cathodes
(Royal Society of Chemistry, 2019-05-17)
Layered sodium transition metal oxides with the P2 structure, e.g. Na2/3[Ni1/3Mn2/3]O2, are regarded as candidates for Na-ion battery cathodes. On charging, extraction of Na destabilizes the P2 phase (ABBA oxide ion stacking) ...

FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides
(Elsevier, 2015)
Exceptional fracture toughness levels exhibited by WC-Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development ...

Influence of the remnant magnetization, size distribution and content of soft magnetic reinforcement in micro-mechanical behavior of polymer matrix composites
(Elsevier, 2019-10)
In this work, the influence of the remnant magnetization, size distribution and content of soft magnetic reinforcement in micro-mechanical behavior of polymer matrix composites (Fe81Ga19/silicone) are evaluated. Melt ...

Captando la atención del alumnado en el estudio de Ciencia de los Materiales a través de un cambio metodológico
(Universidad de Sevilla, 2019)
La Ciencia de los Materiales es una rama común de conocimiento a todas las ingenierías que no suele tener el peso que merece. No se transmite a los alumnos la importancia que tendrá en el desarrollo de su vida profesional. ...
