Description

Instead of molecules that absorb light based on their molecular orbitals, this episode talks of nanostructures and their materials that refract light based on interference of light waves. We start with Robert Hooke who described this process in his book Micrographia. We continue through Isaac Newton and Lord Rayleigh. We discuss Eli Yablonovitch's photonic crystals. We mention various kinds of natural structural colorants in the living and non-living worlds, from minerals to insects to bacteria to plants. Then we list several attempts to synthesize structural colorants, and why they might prove useful.Support the Show.

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.
