Penn MRSEC researchers Stebe and Lee developed a 3D-printable ink that, after extrusion, spontaneously phase-separates into a bicontinuous oil-water emulsion stabilized by fumed silica nanoparticles, locking in two interpenetrating channels with sub-micron domains while the printed object holds an arbitrary centimeter-scale shape.

Penn MRSEC researchers Durian and Katifori built a network of custom bistable electronic elements whose pattern of edge voltages records the history of how the network was driven, inspired by the multistable flow behavior seen in plant vasculature.

Penn MRSEC researchers Good, Chenoweth, and Patel designed short disordered peptides that assemble into stable, gel-phase coacervate particles, loaded them with proteins of interest, and delivered them into living cells without any gene transfer, where the particles act as designer biochemical compartments that capture and degrade native target proteins.

The 13th Annual PREM Symposium took place in San Juan, PR and focused on artificial intelligence and autonomous experimentation. The day consisted of 5 talks from Penn PD/GS and 33 poster presentations from UPR students, which served as an opportunity for presenters to not only further develop their science communication skills but to also provide participant with a platform to showcase the amazing work being conducted within the collaboration.

In a collaborative effort between the University of Pennsylvania MRSEC (LRSM), the University of Delaware MRSEC (CHARM), and the University of Delaware Energy Frontier Research Center (CPI), 36 summer undergraduate research scholars engaged in a day designed to encourage connection and science exploration through shared experiences across MRSECs. 

Penn MRSEC researcher Janmey and colleagues showed that mechanical shear strain on fibrin gels — the protein scaffolding that holds a blood clot together — speeds up both of fibrin's natural remodeling enzymes: Factor XIIIa, which covalently crosslinks the fibers, and plasmin, which proteolytically degrades them.

The 2026 MRS Fall Meeting & Exhibit returns to Boston, Massachusetts, November 29 – December 4, 2026, at the Hynes Convention Center and Sheraton Boston Hotel, bringing together the global materials research community for a week of innovation.

Spin waves called magnons are an emerging way to carry information with far less energy than today’s electronics and to link qubits in future quantum technologies. How long that information survives is limited by the spin waves’ coupling to atomic vibrations, especially at room temperature.

Wisconsin MRSEC IRG 1 developed a new generative AI model for metallic glasses, called GlassVAE. The model is based on ideas similar to ChatGPT, but adapted to describe the complex atomic structures of glasses.

Two-dimensional (2D) transition metal dichalcogenides (TMDs) have recently been shown to demonstrate non-volatile resistive switching (NVRS), offering significant advantages such as high-density integration and low energy consumption due to their atomic-scale thinness. In the work shown here, density functional theory has been used to analyze the electronic properties of defects in atomically thin materials and their influence on electrical behavior, most notably resistive switching which has potential for application in nonvolatile memory devices and neuromorphic computing.
