### 2020

 May 2020 Graduation: Mahmoud Amin graduated with his Ph.D. His dissertation was titled “Boron Nitride Nanotubes (BNNTs) for Thermal Management and Structural Reinforcement”. May 2020 Graduation: Angelica Lin graduated with her M.S. in Applied Science. She did an honors thesis on the self-assembly of native silk dope. Feb 2020 New Publication: Biomacromolecules (2020) — Liang,… Perera,…Schniepp*, and Rajkhowa* "Protein Paper from Exfoliated Eri Silk Nanofibers". We collaborated with Deakin University in Australia to characterize silkworm silk nanofibrils using our atomic force microscope expertise. We proved that their milling and high-shear mixing techniques can produce microfibers but not nanofibrils reproducibly. (paper). Feb 2020 New Publication: JOM (2020) — Ben H. Skopic and Hannes C. Schniepp* "Peeling in Biological and Bioinspired Adhesive Systems". Here we reviewed all biological systems for which peeling is an important failure mode. Gecko's feet and spider silk proved to be widely studied and therefore receive more attention in our review. (paper). Jan 2020 New Student: Aaron Stapel joined the group as a Ph.D. student. He will be returning to William and Mary after completing his undergraduate in 2016 to focus research on the diatoms. Welcome!

### 2018

 Nov 2018 Discussion of the recent ACS Macro Letters paper reaches #1 on the engineering subreddit for two days receiving over 32,000 upvotes and 800 comments. (Link to thread) Oct 2018 PhD student Dinidu Perera participated in the 3MT Competition and won second place and the peoples' choice award with “Making Spider Man's Silk Ropes a Reality”. Oct 2018 New Publication: ACS Macro Letters (2018) — Wang, Schniepp* "Strength of Recluse Spider's Silk Originates from Nanofibrils". We experimentally determined that recluse silk is entirely made of nanofibrils. (paper). May 2018 New Publication: Nanoscale (2018) — Dickinson, Kumar, Adamson, Schniepp* "High-throughput optical thickness and size characterization of 2D materials". We developed a simple method to measure the thickness of many graphene sheets with atomic precision (press release). Apr 2018 Undergraduate student Chloe Walsh successfully defended her honors thesis, “Self-Assembly of Native Spider Silk Protein” on April 25. Apr 2018 Nanomaterials & Imaging Lab at William & Mary Earth Day 2018: We highlighted the ability of silk to replace synthetic plastics and the importance of our research to achieve this goal. Mar 2018 Ph. D. student Qijue Wang presented his work on Mar. 5, in APS 2018 March Meeting in Los Angeles, CA. Mar 2018 Prof. Schniepp presents an invited talk on “Toughness-Enhancing Linear Metastructure in the Recluse Spider’s Nanoribbon Silk” in the Bio Nano Interfaces and Engineering Applications Symposium at TMS 2018: Annual Meeting & Exhibition in Phoenix, AR. Jan 2018 Ph. D. student Qijue Wang is awarded Arts & Sciences Office of Graduate Studies and Research/Graduate Student Association Conference Funding, William & Mary. Jan 2018 Ph. D. student Qijue Wang is selected to present his work about the structure of recluse spider silk in APS 2018 March Meeting in Los Angeles, CA, Mar. 5-9.
