MMD Lab’s First Paper on Modulating Polymer Mechanical Properties with Electric Fields Now Published

“Can Polyelectrolyte Mechanical Properties Be Directly Modulated By an Electric Field? A Molecular Dynamics Study” has just been published in Advanced Functional Materials. This study was carried out by first author Prathamesh Raiter who just completed his MS in the lab, and the concept came from former postdoc Yuval Vidavsky. Using molecular dynamics, this work […]

New publication in Soft Matter Emerging Investigators Issue 2021

Check out our new paper (led by PhD candidate Xinyue(Joy) Zhang! This work aims to isolate the effect of transient metal–ligand crosslinking on the viscoelasticity of polymer networks. A systematic study combining both experimental results and theoretical verification was carried out through a carefully designed system that has no physical entanglements or phase separation. Also, […]

The inextricable links between distribution, behavior, and ensemble . . .

PhD candidate Michael Buche and Prof. Silberstein just published a paper on the constitutive modeling of polymer networks using statistical mechanics in Physical Review E. This work is the first to accomplish a general derivation that starts from arbitrary non-interacting single-chain behaviors and ends in the Cauchy stress. It highlights the naturally-occurring statistical correspondences that […]

Designing Polymers for Strength and Photodegradation

Our new paper on strong yet UV degradable polymers is out in the Journal of the American Chemistry Society. This work was led by PhD candidate Bryce M. Lipinski in the Coates group. He devised a synthesis approach for isotactic poly(propylene oxide) in order to produce a material that demonstrates immense strain hardening. This iPPO […]

Metallopolymers work out in Macromolecules

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 […]

Two new collaborative publications

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, […]

Mechanochromic Polycarbonate work now out in JACS

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. […]

New publication available in Advanced Functional Materials

Our latest collaborative paper with the Diesendruck group at the Technion is now out in Advanced Functional Materials.  “Highly Stretchable Polymers: Mechanical Properties Improvement by Balancing Intra- and Intermolecular  Interactions” was co-first authored by soon to defend MMD PhD candidate Suwon Bae and Diesendruck group PhD candidate Or Galant. In this work, Or and Suwon used a combination of […]

Non-woven modeling manuscript now out in IJSS

Check out Naigeng’s latest paper in the International Journal of Solids and Structures. In this work extending from the final chapter of his PhD dissertation, Naigeng presents a constitutive model for non-wovens that explicitly includes bond failure as a damage mechanism. This novel contribution to the field build’s on Naigeng’s early PhD work experimentally identifying […]

The Effect of Intrachain Cross-Linking for Glassy Polymers

Suwon Bae’s new paper is now out in Macromolecules. This manuscript presents his molecular dynamics simulations examining the thermo-mechanical behavior of glassy polymers assembled from single chain polymer nanoparticles. Suwon’s simulations showed surprisingly good agreement with our earlier experimental work on the same class of materials. This is our third paper in our ongoing collaboration […]
