You can see a characteristic landscape of the Grand Canyon, with the Colorado River rising, viewed through binoculars. The image stands out because it is unusual to see a watercourse in such an arid place. It may remind some of manganese oxide precipitate in a vial, though that is just imagination.
This composite SEM–BSE image captures the calcium metal counter electrode surface after stripping during the evaluation of emerging calcium battery technologies. Blue–green gradients indicate light elements (C, O, and F), while red denotes Ca. Two closely spaced pits appear to merge, forming a microcosmic convergence. This morphology reveals pronounced interfacial heterogeneity, challenging the common assumption of a homogeneous counter electrode.
This SEM image captures calcium dendritic growth resembling a snowflake, acquired during the evaluation of emerging calcium battery technologies.
