Ripplocations Making Waves

January 24, 2019

MaterialsToday featured recent work on ripplocations, published in Physical Review Materials. stemming from Dr.Barsoum’s collaboration between Drexel University and Colorado School of Mines.

https://www.materialstoday.com/mechanical-properties/news/behavior-of-layered-materials-under-pressure-1/

The work showed, using atomisitic simulations on graphite and instrumented indentation on steel sheets, that layered materials confined under pressure ripple, or buckle, to make waves. In turn, the work has far-reaching implications on the deformations occuring during large-scale geologic processes.

Dr.Barsoum gave the plenary talk covering his decades of research on the MAX phases and more recent work on MXenes, the 2D nanomaterials derived from the former, to start the International Workshop on MAX Phases for Harsh Environments at Poitiers, France, held on Nov. 5-7, 2018. The lecture can be viewed here.

Clarivate Analytics recognizes Dr.Barsoum for his research performance demonstrated by production of multiple highly cited papers that rank in the top 1% by citations for 2018 in the field of Materials Science & Engineering as per Web of Science. Also, among this list are former Layered Solids Group Alumni Prof.Michael Naguib (Assistant Professor, Tulane University) and Dr.Babak Anasori (Research Professor, Drexel University). Other researchers to earn this distinction can be found here.

The distinction derives not from Clarivate Analytics but from his peers, who have time and again acknowledged the influence of your research contributions in their publications and citations.

Congratulations to Dr. Michael Ghidu, who successfully defended his PhD thesis on the interactions between water and ions with MXenes!

Roland B. Snow Award

April 23, 2017

Mike Ghidiu and Sankalp’s SEM images wins 3rd place for the Roland B. Snow contest at MS&T 2017! The images, “Waves of the MXene Ocean” and “Castaway in the Boride Sea” were obtained from cross-sectional micrographs of a free-standing MXene film and the fracture surface of bulk MoAlB.

“Castaway in the Boride Sea”

Congratulations to Dr.Barsoum, for getting elected to the Royal Swedish Academy of Engineering Sciences as a Foreign Member!

Congratulations to Professor Barsoum! He has been awarded a three-year Chair of Excellence at the Neel Institute in Grenoble (France) to investigate the electronic properties of MXenes.

Dislocation theory has been very well established and has been successful in understanding the deformation of metals, but it has never properly explained the ripples and kink bands that are formed when layered materials (e.g. graphite, ice, MAX phases) are deformed. Researches in our MAX/MXene, Computational Materials  Science and Design, and Dynamic Characterization research groups used computational simulations, nanoindentation, and microscopy to find evidence for a new deformation micromechanism to explain the plastic deformation of layered materials like the MAX phases, graphite, and mica. Read more about it in the recent press release by the American Ceramic Society and recent article published in Scientific Reports.

See this video showing a computer simulation of how ripplocations form when graphite is indented.
