  • Unlocking the power of a molecule’s spin

    New research provides a theoretical framework that could help experimentalists better control chemical reactions, with possible implications for recycling rare earth metals.

    A new study led by Joseph Subotnik (right) describes a theoretical framework that could allow experimentalists to have better control over chemical reactions by using a molecule’s spin. Using this framework, future experiments conducted through the Center for Sustainable Separations of Metals (CSSM) with Eric Schelter (far left) and Jessica Anna could help researchers develop more energy-efficient ways to purify and recycle scarce materials such as rare earth metals.

  • From a desert to an oasis: Penn engages in ambitious greening effort in the Sahel
    People gather around a large map placed on the floor.

    In Senegal, the ambitious Dakar Greenbelt project seeks to create an extensive network of ecological infrastructure in and around the city to sustainably address environmental concerns and enhance urban life. With support from David Gouverneur and Ellen Neises, Ph.D. candidate Rob Levinthal in the Weitzman School of Design led two courses that included a field trip to Dakar, that culminated in students presenting their visions for parts of the Greenbelt.
