Crystallization Process and Microstructural Evolution of Melt Spun Al-RE-Ni-(Cu) Ribbons
(MDPI, 2020-03)
The crystallization process, both at the initial and subsequent stages, of amorphous Al88-RE4-Ni8 alloys (RE = Y, Sm and Ce) has been studied. Additionally, the consequences of adding 1 at.% Cu replacing Ni or Al were ...

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) ...
