Former postdoc Yuval Vidavsky and current Phd student Michael Buche’s combined experimental and DFT study on metallopolymers is now out in Macromolecules. This work, which was co-advised by Prof Robert DiStasio from Cornell’s chemistry department, introduces the idea of using neutral nitrogen-based ligands to modulate the stiffness, strength, and reversibility of metal-coordination bond-based crosslinks and thereby tailor the overall mechanical properties. Chemistry PhD student Zach Sparrow from DiStasio’s group was critical in establishing the DFT methodology and running analyses.
Two papers are now available online:
The first, in Chemical Science, led by Stephanie Rosenbloom from Prof Brett Fors’ group is titled “Tailor-made thermoplastic elastomers: customizable materials via modulation of molecular weight distributions”.This is part of our ongoing collaboration with the Fors group on the mechanical properties of tailored polymers.
The second, in Frontiers in Chemistry, led by Dr. Sanaz Farajollahi of the Air Force Research Lab, is titled “Disulfide crosslinked hydrogels made from the Hydra stinging cell protein Minicollagen-1“. This first step into synthetic biology for our group came from Steven Yang’s work at AFRL this past summer.
Goodbye and good luck to former postdoctoral associate Yuval Vidavsky and newly minted PhD Suwon Bae as they move on to the next phase in their careers.
MAE and MSE PhD student matching are now complete and we are pleased to welcome three new PhD students into the MMD lab: Hongyi Cai, Srikar Srivasta, and Zhongtong Wang. Guess we need a new, new group photo – this one’s from the transition.
Graduate students Steven Yang and Michael Buche and Prof Silberstein all presented at the annual Society of Engineering Science Conference at Washington University in St. Louis last week (no minivan this time).
Congratulations to Alwany for winning an Engineering Learning Initiatives undergraduate research grant! Alwany will be working on a high throughput approach to measuring the stiffness of gels.
The MMD lab spent a very rainy Wednesday in the 4-H Youth Building at the NY State Fair encouraging the next generation of polymer mechanics enthusiasts. As always, our silly putty making was a hit.

Our study “Enabling Room-Temperature Mechanochromic Activation in a Glassy Polymer: Synthesis and Characterization of Spiropyran Polycarbonate” is now out in the Journal of the American Chemical Society. The manuscript was co-first authored by Yuval Vidavsky and Steven Yang and was in collaboration with the Coates group at Cornell and the Diesendruck group at the Technion. This new material system has potential for direct application as a damage warning material and as a means for advancing understanding of plasticity in glassy amorphous polymers.
