The History of Chemistry
Chemistry is everywhere, and involves everything. But how did chemistry get to be what it is? I'm Steve Cohen, a chemist and writer, bringing you The History of Chemistry. This podcast explores the development of chemistry from prehistoric times to the present, including the people and societies who made chemistry what it is today. The History of Chemistry is for you, whether you hated chemistry in high school, or got a PhD in inorganic chemistry. We'll explore how chemistry affected art, music, language, politics and vice-versa. Whether it's ancient Greek philosophers, medieval alchemists, or modern laboratory apparatus, it's all here.

Episode 112
Here we discuss the discovery of quantum dots, those small particles hovering between molecule-size and macroscopic-size. We begin with physicist and refugee from Nazis Herbert Fröhlich, whose predictions led the way in the 1930s. Among the researchers we encounter are Aleksei Yekimov, Louis Brus, and Moungi Bawendi. Quantum dots were real, but could they be made reliably of specific sizes? The answer turned out to be yes, but you have to carefully control the conditions to make them.
