Profs. Ying Li and Seok-Woo Lee receives the NSF-MoMS fund ($600,000)!

Profs. Ying Li (Mechanical Engineering, UConn) and Seok-Woo Lee (Materials Science and Engineering, UConn) receives the NSF-MoMS (Mechanics of Materials and Structures) fund, $600,000 for 01/01/2020~12/31/2022.

The title of project is “Unrevealing Mechanics of Anomalous High Strength and Low Stiffness in Polymer Nanocomposites“. This project will investigate the fundamental origin of high strength and low Young’s modulus of sequential-infiltration-synthesized polymer nanocomposites using the advanced computer simulation and in-situ nanomechanical testing system. Polymer synthesis will be done by collaborating with Dr. Chang-Yong Nam at the Center for Functional Nanomaterials of Brookhaven National Laboratory.

Tyler’s Au microparticle paper was published at Scripta Materialia!

Tyler’s Au microparticle paper was published at Scripta Materialia! Congratulations!

This work studied the transition of deformation mode (dislocation nucleation vs. single arm source) using microcompression and statistical modeling. Au microparticles were provided by Prof. Eugen Rabkin’s group at Technion, Israel.

Surprisingly, Tyler has two Scripta Mater papers (the first author for both) in the same volume! Awesome!

Seok-Woo gave an invited talk at NANO KOREA 2019.

Seok-Woo gave an invited talk at NANO KOREA 2019 at KINTEX, South Korea. The title of his talk was “Superelasticity in ThCr2S2-structured intermetallic compounds and their hybrid structures.” This talk summarized all results of superelasticity research that his group has worked on for the last four years.
