Think forging currency is simple? Not so, thanks to chemistry. University of Pennsylvania chemistry professor Eric Schelter will explain how rare-earth elements are used to create fluorescent and ultraviolet dyes that are embedded in dollars and euros to prevent counterfeiting. He’ll also discuss other notable uses of rare earths in electronics and energy technologies, as well as the implications of China’s disproportionate possession—and recent withholding—of these precious metals.
Talks will be held at 5:15, 6:15, and 7:15.
