We are excited to welcome the incoming MatSE graduate class! Students interested in the SMEE research team, particularly our work on carbonaceous build up on structural alloys or metallic thin films, are encouraged to contact Prof. Krogstad.
In a recent publication, authors Gidong Sim (JHU) and Prof. Jessica Krogstad reported a novel metallic alloy that could be a game changer for next generation microelectromechanical systems (MEMS) based on its exceptional strength and thermal stability. The high density of nanotwins lead to unique interactions between dislocations and other strengthening mechanisms (grain boundary strengthening, solution strengthening, etc). For more about this research, you can find a number of press releases:
Ceramic Tech Today: “Stronger, more conductive alloy could replace silicon in MEMS”
Electronics 360 (IEEE): “Super-strength materials for the Internet of Things”
AZO Materials: “New metal alloy could be the solution to demands of futuristic technologies”
Science Daily: “Super-strong metal made for next tech frontier”
Materials Today: “New nickel alloy offers strong alternative to silicon in sensors”

Pralav was recently awarded a fellowship from FMC. The FMC fellowship provides 1 year of support for masters or doctoral students doing research related to the oil and gas industry. Congratulations, Pralav!
Congratulations to Nathan on successfully passing both his qualifying exams!
Our new customized AJA DC magnetron sputtering instrument was safely moved into place in our lab (166MRL) today. Once operational, this system will be a huge step forward in controlling thin film chemistry, microstructure and functionality for complex metallic thin films.
Our new project sponsored by the DOE Early Career program on radiation tolerance in engineering ceramics has recently been highlighted in the Jan/Feb 2017 edition of the ACerS Ceramics Bulletin. Click here for the full story.
