We are thrilled to announce a new collaboration between Masic Lab at MIT, MIT.nano, and The Bahrain Institute for Pearls & Gemstones (DANAT) to explore the fascinating nanoworld of natural pearls. Working with DANAT provides us with a once-in-a-lifetime possibility to leverage our multi-scale materials characterization and artificial intelligence approaches to uncover pearl fingerprints, investigate biomineralization processes, and possibly inspire advancements in sustainable cementitious materials.
