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 81
We talk of historical developments in surface chemistry of the 1960s and 1970s. With new ultra-high-vacuum chambers now available, chemists began to study the surface structure of metals, oxides, and other salts, plus semiconductors. They discovered surface relaxation and reconstruction. They employed techniques such as electron-diffraction and photoelectron spectroscopy, along with Auger-electron experiments and thermal desorption, and total internal reflection of light--all of which are explained in this episode. We end with a brief discussion of two luminaries of the field, Gabor Somorjai and Gerhard Ertl. My Patreon supporters can download a supplemental sheet to help diagram ideas mentioned.
