When thinking of all the solids we use in our everyday life, it is striking how many are made by humans instead of occurring naturally. In the past, making new mixtures of common elements was done in the search for better tools and weapons. Now, scientists search for materials with properties better suited for harvesting solar energy or acting as components in an electronic device. One such scientist is Dr. Tiglet Besara, a physicist at Missouri State University. He stops by STEM Spots to talk about the need and search for new crystals.
