In a paper titled Persistence of Small Polarons in Doped Bismuthate Superconductors, researchers study Ba1−xKxBiO3, which becomes a high-Tc superconductor when doped into a charge-density-wave insulator. They show that short-range lattice distortions and strong electron-phonon coupling persist into the metallic phase. Using resonant inelastic x-ray and neutron scattering plus modeling, the team suggests BKBO’s metallic state is an unusual bipolaronic liquid with persistent polarons.

The Center for Advanced Materials and Manufacturing (CAMM) engaged hundreds of high school students through lab tours and discussions during the 2024-2025 school year. Over the summer, CAMM expanded its outreach to younger students in Knoxville, working with local community centers to host hands-on STEM workshops. Activities included tensile testing, materials games, and demonstrations with ferrofluids and shape memory alloys. This initiative not only educated local youth but also enhanced awareness of CAMM’s programs while providing valuable experience for student participants.

An article in the journal MRS Advances documented the outcomes of a summer research program for high school students based at the University of Puerto Rico, in partnership with the Penn MRSEC. Over the past two decades this program has engaged nearly 400 students in hands-on materials science research since 2005, with 84% pursuing STEM undergraduate studies.

This University of Pennsylvania program immerses students in hands-on materials research while incorporating a recently piloted initiative: training participants to become effective science communicators. While students spend 10 weeks conducting advanced research projects, they simultaneously develop crucial skills in translating complex scientific concepts for broader audiences, particularly younger students.

Scientists at the University of Pennsylvania discovered a unique self-assembling network structure that forms when certain liquid crystal materials separate. These networks spontaneously create intricate patterns of filaments and disc-shaped structures through a series of physical transformations driven by competing forces.
