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 .

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.

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?!?

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 :)

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. I asked you what is your favourite episode and the result said it was the episode "Breathe in, Breathe Out - Oxygen Transfer in the Blood".
The survey is still open and you can still submit an answer under https://forms.gle/LihJiny4jncB6h2A6 . Let me know what episodes you like best and we shall replay them over the course of the summer.
I hope you all enjoy your summer. Stay safe and take care :)
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.

After talking about red blood cells two episodes ago, this episode looks at a different bodily fluid. One that helps in the digestion of fats. We are talking about bile. A liquid associated with bad experiences, but is essential to our survival.

In this episode I confront the horrible memory of my one and only bad car crash. I only remember fragments, but the airbag was a big part of the memory. If you want to know how explosions save lives everyday on the road, then tune in.

Oxygen in, Carbon Dioxide out. We learn this basic paradigm about breathing from a very early age on. But how does it work? From a chemical viewpoint this is a lot of fun! So let’s look into it 😊

I always found the concept of energy in the human body very intriguing… or in any organism for that matter. The term energy is very abstract to me. For example, there is a difference to “having the energy to go for a walk” or “the energy to power the oven”. One phrase clearly describes energy as electricity and the other is the energy needed for an activity that we humans undertake. So what is energy in a human being or an animal?

Space. The Final frontier… a friend of mine asked me if there is chemistry in space and how it is different from the chemistry, we observe here on Earth. This is an exciting topic. So exciting that I had to make a podcast episode about it.

Please note: I made a mistake in this episode. I called the analytical method “nucleor magnetic resonance spectroscopy” accidentally “nuclear magnetic resonance spectrometry”. I apologise for this error.

I always tried to avoid making an episode about making alcoholic beverages, because there is already so much great content about it and I did not see the extra value in talking about it. For this episode, I shall break this taboo, by talking about distillation. A technique that is used for making spirits, but also for so much more, which is why I only mention spirits at the end as a side note. I hope you enjoy listening to it.

Batteries are ubiquitous in daily life and I took them for granted for such a long time that I felt obliged to write an episode about them. Especially since they work thanks to a very basic concept called Redox Reactions.

Our 2020 new year’s celebration had to look quite different this year. The Belgian government had to restrict contact, so no extended family, and no fireworks this year. All for very good, Corona-related reasons. This meant for us that we had to find an alternative, so that we could still give our 3-year old daughter a little spectacle. With glow sticks and chemiluminescence in our back packs, we then went on to celebrate a very special and very different new year. This podcast we shall use to understand chemiluminescence, the phenomenon that allowed for us to have a nice evening 😊
