Andy’s collaboration work with Prof. Franky So at NC State University titled, “Cavity Engineering of Perovskite Distributed Feedback Lasers,” was published in the journal ACS Photonics. Congratulations!

Ethan received 3rd Place for the Best Poster Competition at the 2022 NASCENT REU Research Symposium. Serving as Ethan’s mentor, Saurav was also recognized, receiving 1st Place for the Best Mentor Competition this year. Congratulations to you both!

Kun-Chieh presented his work on “Key Wavelength Selection for Optical Emission Spectroscopy Metrology of Direct-Metal Laser Sintering” at the 2022 Solid Freeform Fabrication (SFF) in Austin, TX. Great job!

Ethan presents his research on “Fabrication of Nanostructures using Binary Colloidal Nanosphere Lithography” at the UT Summer REU Research Symposium. Congratulations Ethan!

Chang Group attends the 65th International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication (EIPBN) in New Orleans, LA. Saurav presented a talk on EUV colloidal lithography, Andrew presented a talk on nanoparticle dispersion in super hydrophilic nanostructure, and Vijay presented a talk on multilayer nanolattices. In addition, Kun-Chieh presented a talk remotely on low-RF power HBr silicon etching and Sam presented a talk remotely on anti-dust surfaces. Congratulations everybody!

Gorgeous day on Lady Bird Lake to celebrate everybody’s accomplishments this year!

Yummy Dim Sum for lunch to regain some calories.
