144: Rare as Hens' Teeth

The History of Chemistry ·

2024/10/28

Here we explore the history of unusual and uncommon isotopes of known elements on the periodic table. We discuss the (almost) true statement that all isotopes of an element react the same. Then we reach inside the atomic nucleus and hear of theories to describe nuclear structure and--hence--stability of various isotopes, beginning with Dmitri Ivanenko's work. We learn of the best model, shell structure, and its failings that appeared in the 1980s. Then we talk about half-lives, and how short ...

The History of Chemistry ·

2024/10/14

Science-fiction writers (and scientists) have been promoting molecular transistors since the 1950s, and we explore the history of why that hasn't happened yet. We start with the parallel sci-fi writer (and biochemist) Isaac Asimov's "molecular valves" and physicist Arthur von Hippel's "molecular engineering." We talk of military projects that failed, and theoretical ideas that take a lot of engineering to make them work.Support the show Support my podcast at https://www.patreon.com/thehistory...

140: Chemical Paranoia

The History of Chemistry ·

2024/09/29

We start with the first chemical conspiracy theory from 1996, "chemtrails." Then we move to another popular chemical hoax, "alkaline water" somehow being healthy for you. Related to that are the bizarre "hexagonal water" and water memory ideas. Other creative pseudochemical hoaxes are denial of global warming and the gasoline pill, creating fuel from non-fuel with merely a pill in your liquid. There is the fun cryogenically-cooled audio cable hoax (if you are into high-fidelity audio). There ...

The History of Chemistry ·

2024/09/15

We finally get to discuss what the term "aromatic compound" means in chemistry, from Michael Faraday's report in 1825 of a new organic compound (we call it benzene), to von Hofmann's first use in 1856 (without defining it) of the term "aromatic". We examine the ensuing controversies and definitions of "aromatic compound," how people modeled molecularly and diagrammatically what that meant, and current discussions over the word.

Aerogels, those feather-weight materials, have a century-old history. We begin with Samuel Kistler, the inventor of the first aerogels, and move forward through time with loss of interest in them, then revival of interest in the 1970s. We learn about gradual improvements in their fabrication over time. Then we talk of their fascinating properties, and then their uses.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistr...

2024/09/01

Artificial intelligence, or AI, can be applied to chemistry, too. Here we discuss a brief history of AI, especially for chemistry, beginning with Djerassi's DENDRAL program. We talk of the current problems in chemistry to which AI is being applied over the last couple of decades. We also examine what is not doable (yet) in chemistry with AI.Support the Show.

135: Bond, Chemical Bond

The History of Chemistry ·

2024/08/25

In which we consider what, really, is a chemical bond. Lewis and Langmuir promoted the idea that bonding was sharing of electron pairs. Then we hear about Slater, Hellman, and Ruedenberg's discussion of how covalent bonding works. Kossel and Lewis also introduced ionic bonding. Finally Drude and Lorentz offered metallic bonding. But there are more chemical bonds: the hydrogen bond, the halogen bond, the mechanical bond, the van der Waals force, multi-center bonds, and metallophilic bonds.Supp...

2024/08/18

In which we talk about the fastest spectroscopy yet, attosecond spectroscopy, which can resolve electrons moving around atoms. The topic begins with Christian Spielmann in 1997, working to get shorter and shorter laser pulses, and continues with Ferenc Krausz. We discuss what you might be able to inspect using these short light pulses, such as how the shape of atomic orbitals oscillates after ionization, how you can change the opacity of a substance for a brief moment, and fluctuations of wat...

The History of Chemistry ·

2024/08/11

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 bacter...

2024/08/04

This episode concerns the phenomenon in organic chemistry of classifying a set of similar reactions by a single umbrella name. Most named reactions honor a person, but not always. We discuss the early history of named reactions from the 1870s onward. We then talk about the slant of named reactions towards white men, and away from other people, and even whether that can be a problem for minority and women chemists.

Polyfluoroalkyl substances, or PFAS, seem to be ubiquitous now in the environment and the news. In this episode I delve into why chemists found these compounds so fascinating and useful. Then I discuss some history of how the world finally learned how dangerous these compounds can be if used and disposed of improperly. Finally I talk of some possible methods chemists are currently researching on how to remove PFAS from the environment.Support the Show. Support my podcast at https://www.patreo...

The History of Chemistry ·

2024/07/21

Mechanochemistry, using purely mechanical processes to run a reaction, is much less known in the chemical world, but has been around since the ancient Greek Theophrastus described a mechanochemical process. We describe the history of mechanochemistry from then through its rediscovery by Michael Faraday, and the first systematic attempts to understand it by Mathew Carey Lea. He got into a dispute with Walthère Spring over "first rights" to publication. The 20th century was when mechanochemistr...

In which we learn of the history of graphite, its molecular structure, and electrical properties. Then we discuss the isolation of thinner and thinner layers of graphite through the mid-to-late 20th century. The first isolation of a single atomic layer of graphite, called graphene, was accomplished in 2004 by Andre Geim and Konstantin Novoselov, which set off a new flurry of chemical research, much like the discovery of buckminsterfullerene two decades earlier. Then we discuss the special pro...

In which we discuss the entry of People of Color into chemistry, mostly in the USA. We start with the first Black to get an Ph.D. in Chemistry in the USA, St. Elmo Brady, and work forward through the 1940s through the 1960s. We discuss various organizations to assist people of color in chemistry (and other sciences), such as NOBCChE, SACNAS, AISES, and the Society for Asian Scientists and Engineers. We examine a similar problem in the United Kingdom which has no independent assistance organiz...

The History of Chemistry ·

2024/06/23

In which we talk of a huge problem currently plaguing chemistry (and science in general), the "paper mill," in which researchers pay to get their name attached to others' publications, or they write fraudulent publications and pay to get them in print. We hear of a Chinese firm discovered to be such a broker, possible reasons why chemists would fake research, and specific examples of chemical fraud. One insidious problem is faked crystallographic data on molecular structures, uploaded to repo...
