Abstract:
Our ability to image surface and bulk features of materials plays an important role in the field of nano-scaled materials research. Even more desirable is the capability to simultaneously image morphological and structural changes that occur on the surface and within the bulk of a material with additional stimuli, such as during in situ heating, in situ oxidation, or under tensile stress. In this presentation, I will give two examples of using electron microscopy for solving cosmochemistry and materials problems via an interdisciplinary approach. The first example is to simulate micrometeorite impacts via in situ heating of lunar soil collected from the Apollo Mission. I will then present in situ SEM/TEM tensile testing of carbon-linked graphene oxide nanosheets using a MEMS device. These studies have established new methodologies for materials science and lunar and planetary research.
