Text of Abstract
Gallium is a liquid metal that form an elastic native oxide skin. The oxide skin surrounding the liquid metal manifest creases on the air-liquid metal interface. A high energy Concentric Backscattering Detector (CBS) is used to obtain an electron microscopy image which captures an enhanced contrast image of the wrinkles present on the interface. The crinkles resemble fiery flames, when false color is applied. This image reveals the rich interfacial phenomenon displayed by liquid metals which is yet to be properly understood.
