Vijay’s paper titled, “Precise control of the optical refractive index in nanolattices” was published in Optics Letters. Congratulations!

Congratulations to Dr. Chang for being honored with the “Best Faculty Mentor Award” at the Walker Department of Mechanical Engineering in 2023!

The Chang group has been awarded the NSF PFI grant titled “PFI-TT: Advanced Materials for Augmented/Virtual Reality (AR/VR) Applications.” The grant will support their research on the use of ultra-low refractive index nanolattice materials in AR/VR devices.

Jeffrey’s work on “In situ monitoring of sapphire nanostructure etching using optical emission spectroscopy“ was published in the Journal of Vacuum Science and Technology B. Congratulations!

Vijay’s work on “Investigation of polymer template removal techniques in three-dimensional thin-shell nanolattices” was published in the Journal of Vacuum Science and Technology B. Congratulations!

Andrew’s work on “Identification of dust particles on a periodic nanostructured  substrate using scanning electron microscope imaging” was published in the Journal of Vacuum Science and Technology B and was selected as Editor’s Pick. Congratulations!

Briana’s work on “In situ metrology of direct-write laser ablation using optical emission spectroscopy”  was published in the Journal of Vacuum Science and Technology B. Congratulations!

Ethan’s work on “Fabrication of hierarchical nanostructures using binary colloidal nanosphere assembly” was published in the Journal of Vacuum Science and Technology B. Congratulations!

Saurav’s work on “Modeling the co-assembly of binary nanoparticles” was published in Nanotechnology in collaboration with Prof. Franky So at NC State University. Congratulations!

Cody’s work on “Characterization of porosity in periodic 3D nanostructures using spectroscopic scatterometry” was published in the Journal of Vacuum Science and Technology B. Congratulations!

Chang Group attends the 66th International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication (EIPBN) in San Francisco, CA. The group presented talks on Antireflection sapphire nanostructures by Jeffrey, Anti-dust nanostructures by Andrew, Multilayer nanolattices by Vijay and Metrology of periodic 3D nanostructures by Cody. The group also presented posters on EUV colloidal lithography by Saurav, Metrology of Direct Write Laser Ablation using OES by Briana and Fabrication of nanostructures using colloidal nanosphere assembly by Ethan. In addition, Saurav also participated in the EIPBN startup contest where he presented a poster and made an elevator pitch on Fabrication of ultra-low refractive index nano-lattice material and Dr. Chih-Hao Chang served as the program chair of the conference. Congratulations everybody!

Briana and Rachel have finished their undergraduate journey and graduated with their BS degrees! Both have been Undergraduate Research Assistants with the group since 2021, and will be dearly missed! They will continue their graduate studies to pursue PhD degrees, Briana at MIT and Rachel at Georgia Tech. We are proud of what you have accomplished in our group and look forward to your future contributions to engineering and science!

Briana has been selected as a recipient of the prestigious NSF Graduate Research Fellowship Program (GRFP)! Congratulations!

Congratulations to Saurav for completing the NSF National Innovation Corps Teams program! The goal of the program is to support innovators in developing technologies with commercial potential and help move their ideas from the lab to the marketplace. Read about the work from Team 3D Nanotech!

Sam’s journal paper “Engineering Large-Area Antidust Surfaces by Harnessing Interparticle Forces“ has been published in the journal ACS Applied Materials & Interfaces. This work is funded by an SBIR grant from NASA in collaboration with Dr. Stephen Furst, founder and CEO of Smart Material Solutions. You can also read about the research in a News article by the Cockrell School of Engineering at UT Austin. Congratulations!
