  • A better building block for creating new materials

    Researchers describe a new way to synthesize organic “Legos,” a chemical framework that can be easily modified and controlled to create new materials with unique properties.

Large porphyrin structures (labelled as TAPP) form an egg carton-like lattice that forms multiple stacks, with pyridine molecules (shown in blue) filling the spaces in between the layers.

    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.
