Andrew received the Honorable Mention for the TechConnect World 2026 Student Best Abstract Award! Congratulations!

Mehmet received 2nd Place at the ME Graduate Student Poster Competition for his research on “Mechanically Robust Antireflection Sapphire Surfaces via Nanopillar Arrays”. Congratulations!

Mehmet’s work on “From resilience to scratch resistance: Engineering the deformation mechanisms of nanostructured surfaces” has been accepted by the journal Nanoscale. Congratulations!

Andrew’s recent paper, “Nanoparticle Dispersion and Separation in Superhydrophilic Nanostructures,” has been featured on the RSC Applied Interfaces blog. The post highlights our work on how nanoparticles interact with engineered nanostructured surfaces during wicking and transport, and the potential impact of this research on separation, contamination control, and advanced surface design.

Thanks to the Royal Society of Chemistry for the feature and to everyone involved in the project. You can read the post here: Hear from our authors: Andrew Tunell and Chih-Hao Chang.

Andrew’s paper has been featured as the front cover of Journal of Vacuum Science & Technology B. Congratulations!

Andrew’s work on “Investigation of electrostatic effects between charged particles and nanostructured surfaces” has been published by the Journal of Vacuum Science and Technology B. Congratulations!

Ethan’s work on “Photoresist characterization using a tabletop extreme ultraviolet source at 30 nm wavelength” has been published by the Journal of Vacuum Science and Technology B. The article was also accompanied by a featured article in AIP Scilight. Congratulations!

Andrew’s paper has been featured as the front cover of RSC Applied Interfaces. Congratulations!
