Mummies are, perhaps, the easiest go-to costume for Halloween: grab some bandages, drape yourself in them, and job done. However, there’s a little more behind the traditional embalming process used in Ancient Egypt, as well as a surprising amount of chemistry. Here we take a look at the chemicals used in the process, and how modern chemistry can help us identify them.
All matter is made up of atoms. This is something we now take as a given and one of the things you learn right back at the beginning of high school or secondary school chemistry classes. Despite this, our ideas about what an atom is are surprisingly recent: as little as one hundred years ago, scientists were still debating what exactly an atom looked like. This graphic takes a look at the key models proposed for the atom, and how they changed over time.
On this day in 1896, Wallace Carothers was born. Listed by C&EN magazine in their recent list of scientists who should have won a Nobel prize, we have Carothers to thank for nylon, which can be used in clothing, carpets, car parts and more. Here’s a quick look at the chemistry behind the discovery.
Extremium, catium, cyclonium and pandemonium: elements that you won’t find in the periodic table in classrooms and laboratories. However, they’re all names that have been suggested but rejected for elements in years gone by. This table takes a look at some of the different names that have been suggested or used in the past for various elements; below, we examine their origins, and the reasons for their rejection.
