Metals and alloys sit at the heart of materials research, but their susceptibility to surface oxidation has impeded their investigation in atomically thin form or as pristine surfaces exposed to the ambient environment.</p></div></div></div> Tue, 20 Oct 2020 15:05:21 +0000 divya.abhat 6601 at https://mrsec.org Active Interfaces Between Highly-Deformable Nanomaterials https://mrsec.org/research/active-interfaces-between-highly-deformable-nanomaterials <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p>This IRG will transform understanding of the link between deformations of 2D heterostructures and molecular assemblies, and the resultant changes in electronic, chemical, and optical properties.
