Cu-based brake pads applied in high-speed railway trains containing Ni-coated graphite flake and uncoated graphite flake were fabricated by powder metallurgy. The braking properties of the brake pads were investigated by a scaled down testing apparatus with the pad-on-disk configuration under various braking speeds and braking pressures. Compared with the brake pads containing uncoated graphite …
Element 29 in our International Year of the Periodic Table series is zinc. Commonly used to galvanise other metals, it’s found in cars and streetlights. Its compounds are used in sunscreens, cosmetics, and medicines. Galvanising is the process of coating iron and steel in a thin coating of zinc. This coating prevents oxidation by itself corroding …
Element 29 in our International Year of the Periodic Table series is copper. Though it might not have copper’s characteristic orange-red colour, the Statue of Liberty is made of this metal, and it’s also found in our everyday lives in the wiring and electronic devices in our homes. The Statue of Liberty is coated in …
Nickel is element 28 in our International Year of the Periodic Table elements series. One of a select number of magnetic elements, it’s found in many of the coins of various currencies, and is also found in the heating elements in your oven and toaster. Nickel is one of those elements that you encounter a …
Dorothy Hodgkin was born on this day in 1910. She’s famed as one of only four women to have won a Nobel Prize in Chemistry, and the only British woman to have done so. This graphic takes a look at the work that earned her the prize. View more posts on chemistry history on the …
Element 27 in our International Year of the Periodic Table series is cobalt, found in pigments, jet engines, and used in the sterilisation of medical equipment. If you’re ever dabbled in painting or pottery-making, you may have come across the shade cobalt blue. It’s, as the name suggests, a blue pigment which is both used …
There are 118 elements in the periodic table – but they’re not all made in the same way. This graphic looks at some of the processes which generate elements in stars, and how the elements they can’t make are made by humans.

Here’s the monthly summary of chemistry stories that have hit the news. This month features news on the observation of the universe’s first molecule in space, a new method for making graphene using hair removal wax, and more! Larger summary images for each item are provided below, along with links to articles and studies for …
Element 26 in our International Year of the Periodic Table series is iron – found in our blood, on the Red Planet, and also responsible for our own planet’s magnetic field. Blood’s red colour comes from the iron-containing haemoglobin. It’s not just the colour of blood that haemoglobin contributes; it’s also responsible for ferrying oxygen …
