Acoustic Processes in Materials

‐ May 22, 2019 12:30pm

The coupling of acoustic energy with materials structures and processes is at the core of current and emerging application areas, such as ultrasound-enabled materials characterization, structuring, and processing. High concentration of acoustic energy has been shown to provide conditions for the synthesis of unusual material phases and structures, while reports on acoustic activation of surface diffusion, desorption, and catalysis hold high promise for applications where heating must be avoided or rapid switching of surface conditions is required. Some of the recent scientific and technical advances in the general area of acoustically enabled material synthesis, processing, and characterization are reviewed in the May, 2019 issue of MRS Bulletin.

The talks in this webinar expanded on the MRS Bulletin issue, and an interactive Q&A session was held with the speakers following each talk.
