We start with a 1927 patent awarded to George Washington Carver, an agricultural chemist, for a locally-sourced Prussian blue. We learn a bit about Carver's life, education, and hobby of painting which may have led to the patent. We examine the patent in some detail, and then hear how it's been revived by a modern artist. Then we discuss other blue pigments throughout history, ending with the newest blue, an accidental discovery in a laboratory in 2009.Support the showSupport my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

They delve into scientific studies, regulatory concerns, and personal anecdotes to provide a comprehensive overview of this controversial herbicide. 00:00 Introduction to Weed Killers 01:34 Listener's Question on Glyphosate 03:24 Understanding ...

From glowing plastic stars on bedroom ceilings to quirky novelty items, most of us have encountered the magic of things that shine in the dark but what’s really behind the glow? Andrew and Taylor dive into the science of photoluminescence, breaking down the physics of how it works and the materials that make it possible. Join them as they explore the two main glow-in-the-dark methods—phosphorescence and fluorescence—and reveal what makes each one shine. This episode of the Materialism Podcast is sponsored by the American Ceramics Society. Check out the ACerS learning center with over 20+...

⏳Quantum Torah: Time's Flexibility in Jewish Law and Physics Rabbi Shlomo Ezagui's article, 'Quantum Torah: Time's Flexibility in Jewish Law and Physics,' explores the surprising parallels between ancient Jewish law and modern quantum mechanics, specifically concerning the concept of time's flexibility. The author highlights the Jewish legal principle of breira, or retroactive clarification, exemplified by the eruv techumin (a rabbinic mechanism allowing for extended travel on Shabbat). This legal concept suggests that a present need can retroactively determine a past intention, as if that ...

La puntata di oggi si intitola "Vita universitaria - Parte III: Studiare Scienza dei Materiali", scritta e condotta da Cristina Paganini insieme con Francesco Ricco, Matteo Tumiatti e Manuel Zanaga (studenti di Scienza dei Materiali).Cosa significa studiare Scienza dei Materiali? Perché sceglierlo? Quali sono i contenuti, le applicazioni possibili e la visione del mondo che ne deriva?

As we enter the summer season, many of us will spend countless hours outdoors. We often discuss tick awareness and tick-borne illness, but one tick in particular is getting a lot of press these days. In case you needed another reason to be mindful of ticks, today we discuss Alpha-gal Syndrome. In today’s episode we explore the science behind alpha-gal syndrome – a rare and serious allergy to red meat and other mammal products triggered by a bite from the Lone Star Tick. Tune in to learn how to recognize symptoms and why this syndrome is spreading across many regions and many countries. ...

Send us a textIn this episode, the team recaps a busy season of spring seminars across the country in partnership with CEM, Agilent, and other ICP Alley collaborators. From Santa Clara to Baton Rouge, our chemists share what they presented, what they learned, and the real-world questions they answered — from mercury washout and silicon rinsing to internal standard selection and leaching practices.They also reflect on what made these events so valuable: industry collaboration, hands-on instrument demos, and face-to-face connections with fellow chemists. Whether you attended or missed the tour...
