Thermal stability and decomposition kinetics of NdNiO3− δ at 1 bar of O2
Bassou, A. A.; Machado, P. J.; Gomes, M. M.; Manjunath, B.; Vilarinho, R.; Silva, Bruna Andreia Nogueira Airosa; Oliveira, José A.; Almeida, B. G.Despite the interest in rare-earth nickelates for applications, their processing under 1 bar of oxygen pressure is still challenging. In this work, we report the co-precipitation synthesis, thermal stability and thermally driven decomposition of NdNiO3 phase, in order to determine the synthesis parameters towards a pure perovskite phase. We concluded that using a 1% molar excess of Nd during preparation and pos...
Aging and attentional set shifting on WCST: An event-related EEG study
Fernandes, L. S.; Ferreira, D. S.; Almeida, P. R.; Dias, Nuno Sérgio MendesAs the brain ages, it suffers several neurochemical, structural and functional changes. These deficits are primarily reflected on daily memory tasks. In the present work, we use the Wisconsin Card Sorting Task (WCST) task to assess P300 component of the event-related potential (ERP) as a marker for aging. Considering age-related effects, WCST was applied to young, middle-aged and elder participants. Early-late ...
