The Janmey and Shenoy groups in IRG-2 studied multiaxial response of soft tissues (top left image). Measurements (Janmey) and a theoretical model (Shenoy) show that the tissue rheology emerges from an interplay between strain-stiffening polymer networks and the volume-conserving cells within them.
A collaboration between members of IRG-1 (Fakhraai, Lee, Turner) explored the properties of disordered packings in different environments. Specifically, they investigated the effects of extreme confinement on the thermal properties of polymer-infiltrated nanoparticle films.
This IRG-1 collaboration, is focused on the mechanics of disordered solid granular matter and is led by Arratia, Ma (post-doc, Yodh lab) and Jerolmack (MRSEC collaborator).
MXenes are two-dimensional (2D) ceramics made of transition metal carbides and nitrides. Unlike other 2D ceramics, MXenes have inherently good conductivity and thus are promising for various applications. Probing the local physical properties of MXenes monolayers is important for the understanding of their functional performance. Nebraska MRSEC researchers in collaboration with their colleagues at Drexel University have developed an improved method for synthesis of monolayer membranes of Nb4C3Tx MXene.
Nebraska MRSEC researchers have proposed a new concept to design high-performance ferroelectric tunnel junctions with enhanced tunneling electroresistance (TER). This design exploits property of a polar oxide material to create an ionic charge at the interface.
Northwestern University MRSEC Shared Facilities play a central role in education and outreach programs. For example, the Northwestern University Center for Atom Probe Tomography recently hosted a two-day workshop to offer hands-on user training in the latest methods in atom probe tomography including materials analysis and visualization tools.
In partnership with the Northwestern University Kellogg School of Management, McCormick School of Engineering, Pritzker School of Law, and Innovation and New Ventures Office, the Northwestern University MRSEC fosters a comprehensive innovation ecosystem that allows fundamental research to be transferred to the market via startup companies.
The Northwestern University MRSEC sponsors the Women Supporting Women in the Sciences initiative, which is a partnership with the University of Dodoma and the Nelson Mandela African Institution for Science and Technology in Tanzania. This initiative develops professional development workshops for female STEM students.
The Northwestern Prison Education Program is an initiative to provide a high-quality liberal arts and STEM education to incarcerated students in Illinois in partnership with Oakton Community College and the Illinois Department of Corrections. Responding to the crisis of mass incarceration, NPEP fills a vital need by being the only degree-granting program in the State of Illinois with a full liberal arts curriculum including STEM courses for incarcerated students.
Through molecular dynamics simulations, the Northwestern University MRSEC Super-Seed has studied the dependence of pore size dimension on the desalination properties of COF membranes.
