From atomic scale to macroscale, ripplocations describe deformation of layered solids

By Lisa McDonald / February 8, 2019

How do layered solids deform? According to new research at Drexel University, “ripplocations” account for most deformations in layered solids, from the atomic scale to the macroscale.

Ripple effect: Ripplocations help explain dislocation theory in layered materials

By April Gocha / September 30, 2016

Researchers at Drexel University report on their studies of MAX phase ceramics that describe a completely new observation of how materials deform—a finding with broad implications for various other kinds of layered materials.

The cover story of the April issue of the ACerS Bulletin described the interesting family of carbides and nitrides known as the MAX phases. Their name refers to their composition, where M is a transition metal, A…

Credit: Babak Anasori, Drexel University Graphene, a two-dimensional sheet of carbon, has been the subject of much research since it was discovered in 2004. Its basic properties are fairly well documented, and papers are appearing about possible applications, for example, as supercapacitor electrodes…
