Functional Groups in Organic Compounds

Today’s graphic is a little more basic, but is something that I’m hoping to eventually develop into an organic reaction map. The idea for this was to present the various organic compounds that pupils need to learn at A level in a straightforward manner, simply with the formulae, name, and a naming example of each. […]

The Chemistry of an Onion

The latest in the series of food chemistry graphics looks at the chemistry of onions – specifically, what causes their odour, and why chopping onions will make your eyes water. Interestingly, none of the compounds that cause these effects are present in the intact onion; rather, when the cell walls of the onion are damaged […]

Element Infographics – The Transactinides

The final elements infographic looks at the Transactinides. These elements are all synthetically produced, and do not occur naturally; as such their applications are minimal, and their chemistry relatively unknown. Hence this graphic looks more at their general properties, and at some of the scientists after whom a number of the elements are named.

Element Infographics – The Actinides

The penultimate elements infographic focuses on the Actinides. Many of these elements don’t occur naturally, and are produced synthetically, with some of them existing only for a fraction of a second before they decay back into lighter elements.

Why Chilli Peppers are Spicy: The Chemistry of a Chilli

The idea for this graphic came to me whilst saving the chilli peppers from a forlorn looking, aphid-infested chilli plant that’s probably on its metaphorical last legs. I thought it would be quite interesting to look at the origin of the heat in chilli peppers, and how this can be quantified.

Element Infographics – The Lanthanides

This graphic looks at the elements known as the lanthanides – the ones stranded at the bottom of the periodic table, along with the actinides. For a group of elements that doesn’t really get much attention in chemistry teaching until at least undergraduate level, their applications are remarkably widespread and varied. Most modern electronic devices […]
