Silu Guo wins First Place Poster Award at the 2023 Microscopy & Microanalysis meeting

Silu Guo, a fourth-year materials science and engineering Ph.D. candidate in Professor Andre Mkhoyan's research group, recently won a First Place Physical Sciences Poster Award at the 2023 Microscopy & Microanalysis meeting, which consisted of a monetary award and certificate. The 2023 event featured platform and poster presentations, a robust trade show, and the world’s largest annual microscopy exhibition, which showcased the latest instrumentation and accessories. 

Guo's award-winning poster, "Self-healing Crystallization via Radiolysis-Driven Constructive Twist in Rutile-TiO2," featured research on self-healing crystallization via radiolysis-driven constructive twist in rutile-TiO2. In this study, she used scanning transmission electron microscopy (STEM) imaging and electron energy loss spectroscopy (EELS) to study the bond-breakage, atomic movements and crystallization in rutile-TiO₂ driven by radiolysis. Based on these observations and quantitative EELS analysis, she proposed a “2-step rolling” model for the TiO₆ octahedral building blocks located at the crack’s edge of rutile-TiO₂ as a possible mechanism for radiolysis-driven atomic migration.

Congratulations Silu!
