Although successful retrieval practice is beneficial for memory, various factors (e.g., lag and criterion level) moderate this benefit. Accordingly, the efficacy of retrieval practice depends on how students use retrieval practice during learning, which in turn depends on accurate metacognitive monitoring. The present experiments evaluated the extent to which judgments ...

The paper reports a novel approach to achieve self-healing surface hydrophobicity. Mesoporous silica is used as the reservoir for hydrophobic molecules, i.e. octadecylamine (ODA), that can release and refresh the surface hydrophobicity consecutively. A polymdopamine layer is used to further encapsulate silica-ODA, providing a reactive layer, governing release of the ...

Ni(iii)-intermediates are trapped by EPR and UV/Vis spectroscopy in the reaction of a Ni(ii) salt with mCPBA. On the basis of their oxo-transfer and hydrogen-atom abstraction abilities the intermediates are assigned as the elusive terminal Ni(iii)-oxo/hydroxo species. The findings suggest that Ni(iii)-O(H) moieties are viable reactants in oxidation catalysis.
