Drexel University PhD candidate Pedro Amaral and undergraduate Justin Li teamed up to grow this tin crystal in a unique conformation. “Usually, to synthesize tin crystals, two electrodes are simply positioned on opposite sides of a Petri dish,” Amaral explains. “To achieve this crystal, we had one electrode forming a circle around a large crystallizing dish, and the other electrode touching the solution from the top.” The effect was a crystal that grew from the inside out. Amaral and Li created the image as part of a series of 24 photos that hang in the Drexel Chemistry Department. The series is intended both to decorate the department and to introduce undergraduates to the allure of chemistry.
