    Asphalt - Chemie im Straßenbau

    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

    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?

    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?!?

    If you would like to share feedback or have a suggestion for a topic, I can now be reached on twitter under @ChemistryinEve1 or you can leave a comment on my website https://chemistryineverydaylife574446112.wordpress.com/. Alternatively, you can send an email to chem.podcast@gmail.com.

    Summer Re-runs: Prove It! How do we know what chemicals we have? - Part 2: Analysis

    Dear  Chemistry in Everyday Life Fans, I am off this month and as a  consequence, we are looking back on past episodes over the summer.  Today’s re-run is one of the first episodes that I ever recorded by the  name of “Protection from the Sun Pt. 1 – The Ozone Layer”.

    I hope you all enjoy your summer. Stay safe and take care :)
