April 23 is Saint George’s Day, celebrated in particular by a number of countries and cities where Saint George is the patron saint. One of these is, of course, England, though here the celebrations tend to be quite muted and minimal, and certainly nothing in comparison to the merriment that heralds St Patrick’s Day. In Catalonia, however, it prompts a good deal more in the way of celebration, and I made this graphic for the Institute of Chemical Research of Catalonia to illustrate some of its facets.
Roses are the flower most closely associated with Valentine’s Day – and we’ve got chemistry to thank for both their colour and aroma! In this post we take a closer look at the chemical compounds involved.
As we took a look at the complex chemistry of bread-making last week, this week it seemed to make perfect sense to look at some of the chemistry that results from putting the end result of that process into the oven! There are a host of compounds that contribute towards baked bread’s aroma; here we take a look at a selection of them, how they are formed, and what they contribute.
If you’re a dog owner, hot weather inevitably leads to wet dogs, particularly if you live near the sea, a river, or basically any other body of water that looks appealing to your canine companion. It’s probably not escaped your notice that dogs tend to smell pretty awful after getting wet. Why is that? Chemistry and biology combined can help explain.
Today’s post marks a slight detour for the aroma chemistry series. So far, we’ve look mainly at pleasant aromas, but today we turn to a major malodour: that of toilets, and, more specifically, human waste. It might seem like something of a childish subject, but there are some interesting chemical compounds present in the materials we expel from our bodies. There are are also reasons to examine these compounds, as we’ll discover.
Whether you’re a coffee connoisseur or completely unfussy about the manner in which you get your caffeine fix, there’s no denying that the smell of freshly-brewed coffee in the morning is an invigorating one. The chemistry behind this aroma, though, is far from simple; a complex collection of chemical compounds are responsible, and this graphic takes a look at a selection of these.
