Science through the lens.

Research micrographs from the group — SEM, BSE, and false-colour images of Mg alloys, reactive Al powders, and fracture surfaces.

Yin and Yang — the delicate balance of opposing Marangoni flows in liquids, their motion arrested in a solidifying metal droplet. A 50–50 at.% Al–Bi alloy whose composition mirrors the visual symmetry. Taken on a ThermoFisher Scientific SEM.
