CCMR Jumpstart Funding

Cryomech and the MMD lab have won CCMR Jumpstart funding to investigate polymer seals. Undergraduate Kenneth Fang, who has been working in the lab since last spring, will take the lead on this project. Full story within the Cornell Chronicle.

SCPN Based Thermoplastics

Galant 2017 graphical abstract

Our first experimental paper in our ongoing¬†collaboration with the Diesendruck group on single chain polymer nanoparticles (SCPN) is out in Macromolecules. This manuscript presents the first ever mechanical testing on bulk polymers composed entirely of this novel SCPN architecture for which bulk properties can be tailored by changing the degree of SCPN cross-linking. Or Galant and Suwon Bae worked closely together during Or’s stay in our lab last summer to work out the sample preparation and testing methods that ultimately led to this publication.

Meenakshi Defends PhD Thesis

Congratulations to Meenakshi Manivannan for successfully defending his PhD this past Friday! Meenakshi will be the first MMD lab PhD graduate. His dissertation “Multiscale Modeling and Design of Mechanochemically Active Interfaces” covered his last four years of research using computational and analytical tools to discover the key physics governing mechanophore behavior in composites.Meenakshi defense

4-H Career Explorations

The MMD lab hosted a University U workshop as part of the annual 4-H Career Explorations program on Cornell’s campus. Six groups of rising 8th and 9th graders from around NY State rotated through our 80 minute session “Breaking Bonds and Changing Colors: A Mechanical Engineering Take on Chemistry”. Students acted out different types of bonds and conducted their own tensile tests. Although not depicted here, everyone in the lab rotated through running the sessions. Thanks to Alexa Maille and the rest of the 4-H team for a very helpful training workshop and making all the organizational aspects run seamlessly.

Group Outing and Undergrad Welcome

The MMD lab survived its first ever group Cayuga Lake trip. And we even found some other kayakers to take our picture!

Also, welcome to our summer undergraduates Maegan Cremar, Kenneth Fang, and Julia Owens.

Naigeng participates in student paper competition

Graduate student Naigeng Chen was accepted into the the Society for Experimental Mechanics student paper competition earlier this spring and competed this past week at the annual conference in Indianapolis. He presented the approach he has developed over the past two years for determining bond strength in non-wovens.


Simulated Compression of Single Chain Polymer Nanoparticles (SCPN)

Graduate student Suwon Bae has published his work on the thermo-mechanical properties of single chain polymer nanoparticles in Soft Matter. This work is in collaboration with Or Galant of the Diesendruck group at the Technion who spent the summer as a visiting student in our lab. This first ever study on the mechanical properties of SCPN showed through molecular dynamics simulations that many of the design rules for bulk polymers apply to SCPN as well.
