Metamaterials paper published

“Examining the impact of asymmetry in lattice-based mechanical metamaterials” is now published in Mechanics of Materials. This work was led by graduate student Srikar Srivatsa and was in collaboration with the Selva group at Texas A&M. In this study we use a generative algorithm to produce lattice-based metamaterials within a confined design space. We then […]

New paper out in Advanced Materials Interfaces

The Research Article “Enabling Tunable Water-Responsive Surface Adaptation of PDMS via Metal-ligand Coordinated Dynamic Networks” is now published in Advanced Materials Interfaces. This work was led by Xinyue(Joy) Zhang. We demonstrated a new design to enable time-dependent adaptation of a polymer via dynamic functionalities. By embedding dynamic metal-ligand coordination into a PDMS matrix, a reversible hydrophobic […]

Science Perspective on tailoring elastomers

Can materials be both soft and tough? Historically, low toughness has severely limited implementation of soft materials, such as hydrogels, in emerging technologies. Our perspective “Pathways to tough yet soft materials” analyzes state-of-the-art techniques for enhancing mechanical properties of hydrogels. In this article, published in the latest issue of Science, postdoc Nikola Bosnjak discusses novel […]

New papers out on mechanoresponsive elastomer modeling

Dr. Michael Buche’s paper on statistical mechanics derived modeling of mechanoresponsive elastomers is now out in the Journal of the Mechanics and Physics of Solids. Titled “Chain breaking in the statistical mechanical constitutive theory of polymer networks,” it methodically derives a constitutive model for elastomer networks with breakable bonds that encompasses and expands beyond the […]

Update

We’re a bit behind on posting, so here’s a bunch of MMD lab updates in one. Congratulations to Shreya Gowda on another award! This time she’s won Aviation Week’s 20 Twenties – a worldwide competition for top aerospace bound students. We have two new collaborative papers out: “Microstructural evolution of polyurea under hydrostatic pressure” in […]

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 […]
