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.

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?!?

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.

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.

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.

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 😊 If you would like to share feedback or have a suggestion for a topic, I can now be reached on twitter under @ChemistryinEve1 https://twitter.com/ChemistryInEve1.

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… If you would like to share feedback or have a suggestion for a topic, I can now be reached on twitter under @ChemistryinEve1 https://twitter.com/ChemistryInEve1.

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.

Welcome back to the last episode of this Nobel Prize series during which I discuss the technology for which the two research groups around Prof. emmanuelle Charpentier and Prof. Doudna received the joint Nobel Prize for chemistry. This episode will put all the pieces that we encountered over the course of the last two episodes together and finally will explain, how the so-called gene scissors, CRIPS/CAS9, work.

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.
