Layered Metals Used to Show How Nature’s ‘Dislocations’ Occur

A report published in the journal Scientific Reports by a team of researchers from Drexel’s College of Engineering, suggests that, when compressed, layered materials—everything from sedimentary rocks, to beyond-whisker-thin graphite—will form a series of internal buckles, or ripples, as they deform.

In early 2015, a paper published by a group at the Massachusetts Institute of Technology suggested a new deformation micromechanism called “ripplocation,” best described as an atomic scale ripple, occurring near the surface of layered materials. The Drexel team, led by Michel W. Barsoum, distinguished professor and head of the MAX/MXene Research Group, set out to prove that ripplocation exists, not only in near-surface layers of 2-D materials, as suggested by the MIT paper, but throughout the internal layers of thicker, “bulk” layered materials as well. Through a careful examination of computer models, wherein graphitic atomic...
