- 41 - 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 .

Wed, 05 Jan 2022 - 24min - 40 - 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.

Tue, 28 Sep 2021 - 10min - 39 - 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?!?

Sun, 25 Apr 2021 - 14min - 28 - The concept of energy in the human body
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?

Sun, 28 Mar 2021 - 18min - 26 - Distilling the essence - Talking about Distillation
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.

Sun, 14 Feb 2021 - 15min - 23 - Conjugated Systems... no, we are not talking about Latin ;-)
We talked about Glow Sticks, we talked about Fireworks. Now it feels like the right time to look at another big factor in color of compounds, the conjugated systems.

Mon, 01 Feb 2021 - 13min - 22 - Glow Sticks - A new year's saving grace
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 😊

So it was time again to add a little Diesel Exhaust Fluid, also known as AdBlue, to the gas tank of my car. So I stood there in the cold winter temperatures, freezing my, you name it off, and just wished that it would add quicker! Inevitably, one thought popped into my headed: “Why, oh why on earth am I doing this anyways?!” This episode is the final product of my investigations…

Sun, 03 Jan 2021 - 23min - 20 - Radical Dental Filling
This episode is inspired by my wife's recent experience at the dentist where she needed to get a filling done. It was her first and it reminded me of my first (and so far only) dental filling that I needed to get done a couple of years ago. Our discussion about what the dentist did to fill the dental cavity led to this episode. I hope you enjoy it :).

After discussing for 3 episodes the cutting edge technology that led to a Nobel Prize, I would like to return back to more mundane things and there are not many things more mundane than eating bread :-D
This episode will look at the reason why bland bread starts to taste sweet after chewing it for a while. I hope you will enjoy it :)

Mon, 23 Nov 2020 - 16min - 17 - The Nobel Series Part II: Gene Expression
The 2020 Nobel Prize in Chemistry went to Emmanuelle Charpentier and Jennifer Doudna for "for the development of a method for genome editing”. Their work has markedly added to the toolbox available to researchers in the life sciences and in my humble opinion, it is worth talking about. To understand why this work is so important, we will need to have some introductory episodes first and this here is part number II, where we will discuss how genetic information stored in DNA is transformed into biological functions and traits.

Water is all around us and we kind of take it for granted. It is an accepted basis for life and makes our planet inhabitable. Have you guys ever wondered why that is?
Well, water is also a very special liquid. This episode revolves around a specific feature that water has, namely hydrogen bonds, how they function and why they change the way water behaves in comparison to other compounds.

Wed, 26 Aug 2020 - 14min - 11 - Why better not to use heating fuel in your diesel engine?
This episode is based on a discussion I had with an acquaintance at a barbecue. He, being the smarty pants that he is, asked "Do you know the difference between diesel and heating fuel?"... I didn't... I, being the smarty pants that I am, was annoyed by that. With a wry smile he suggested: "Better look it up then." And I did! The result is a not too shabby podcast episode on the difference between the two.
If you want to know why it is a bad idea to use heating fuel in your diesel engine, tune in!

When talking about chemistry, one of the first topics to breach is the chemistry of soap. In the time of a global pandemic, washing our hands has become second nature and at some point at the beginning the stockpiling of soap even led to shortages in some areas.
So let's talk about soap and how it does its job.

I love fireworks, folks. I don't see the spectacle often, but when I do , it is an absolute beauty to behold, especially when it is an entire choreography. I sometimes cannot believe that there are people whose job it is to "make" fireworks. Especially, the development of new ones must be a blast!... in more ways than one :-P.
This episode looks at how fireworks create colour at the sky. I hope you enjoy it.

Proteins are one of the key elements that define life in a way that we know. They have such a vast array of functions it is staggering. Seemingly, every problem and obstacle that an organism encounters, a protein comes to the rescue. Humans have them, other mammals, birds, bacteria, even viruses consist for a big part of proteins.
You want to walk somewhere, you need your muscles, those are proteins. You want to digest food? Guess what? digestive enzymes are proteins. Your skin and hair? Proteins are involved. Pumping blood around your body. Proteins. Immune system. You guessed it. Proteins.
Proteins are such an important part of everyday life that I decided to make an episode about the general features of proteins.
Interested? I am looking forward to welcoming you to this episode of "Chemistry in Everyday Life"
Tue, 05 May 2020 - 11min - 3 - Protection from the Sun Pt. 2 - Sun lotion
The sun is the source of life on this world, yet at the same time it can be very dangerous for us and other lifeforms on earth. The life giving energy that is emitted from the sun to earth's surface needs to be made use of through processes like photosynthesis, but it also needs to be "disarmed" or filtered.
This episode is the second part of a two-part series that looks how we protect ourselves from the sun. In this concluding episodes sun lotion and natural sun protection is in the centre of our attention.

Sat, 18 Apr 2020 - 12min - 1 - Diamond vs. Pencil
On the surface, a diamond and a pencil have nothing in common. One is one of the hardest and valuable materials known to man and the other is a pencil, an everyday object that many people use on a daily basis to write, draw or the medium between the two: scribble. But once we leave the surface behind us and look closer on a chemical level the differences between a diamond and a pencil are actually not that big.
