    Asphalt - Chemie im Straßenbau

    Roads are one of the defining features of modern civilizations, believe it or not. To me and I think most others, the state of the roads in a country gives an idea of the level of development. It does not surprise then that chemistry features quite heavily in how we make roads. A request from a listener, I explore in this episode the chemistry of bitumen and the physical properties needed for a good road. This podcast is still not reactivated, but if you have a topic that you are interested in and do not mind an extended waiting time until I get round to it, drop me a mail under chem.podcast@gmail.com .

    Last episode of Chemistry in Everyday Life: Cyanide Poisoning

    It takes a little bit more than 100mg of cyanide to kill a 75 kg human being. A little more than 100mg and the unfortunate victim will show the telltale signs of “bluish tones of oxygen deprivation mottle the skin.“ Cyanide Poisoning is as old as the usage of chemical compounds containing cyanide and this episode looks at the chemistry that happens in the body during a poisoning. “This will be the last episode of Chemistry in Everyday Life for now. It was a huge amount of fun, but for the usual reasons, I have to suspend this beloved hobby project for an indefinite period of time. I would like to thank you all for listening. I enjoyed this experience immensely and I am proud of what I achieved. Take care everyone 😊” The Podcast will remain online for the time being, but I will not add any new content.

    Why can we digest starch, but not cellulose?

    Both starch and cellulose are made of glucose, one of the main sources of energy for the human body. Yet... we can digest starch that we find in things like potatoes or flour, but we cannot digest cellulose, a compound that is found in virtually every plant... Why?!?

    You look radiant today - Radiotracers and Imaging

    PLEASE NOTE: During the month of August, I will repeat some previous episodes. If you want to influence which episodes will be played, you can click on the following link to part in a 1-question survey. Thanks! https://forms.gle/LihJiny4jncB6h2A6 How can you trace a molecule inside the body? How do you know, how a compound inside the body is metabolised? We will explore these questions in this episode.
