The delayed 2020 Olympics are currently taking place in Tokyo, and setting a number of firsts. Obviously, it’s the first Olympics to take place without a public audience in the stadiums to watch the events. However, it’s also the first Olympics at which the medals are made entirely from recycled metals. This graphic takes a closer look at their composition and how the metals to make them were amassed.
Summers are filled with sunny days to enjoy the outdoors, but you need to bring along the proper sun protection to prevent skin damage. The latest edition of Periodic Graphics in Chemical & Engineering News looks at the chemistry the sun triggers in our skin. View the full graphic on the C&EN site.
How does COVID spread? Of all the questions about the pandemic, this seems like it would be a fairly simple one to answer. But, even several months into the pandemic, the guidance from public health organisations did not recognise the potential for COVID to be transmitted through the air. The latest edition of the Chem vs. COVID series with the Royal Society of Chemistry highlights the point at which scientists called for this mode of transmission to be more widely recognised.
With the ongoing COVID-19 pandemic, air purification technologies have been receiving renewed attention as workplaces look for solutions that will lower their workers’ risk of exposure. In the latest edition of Periodic Graphics in Chemical and Engineering News, we take a look at the different types of air purification and how each of them works.

On this day (16 June) a year ago, the first effective treatment for COVID-19 was announced. The corticosteroid drug dexamethasone, already used to treat several inflammatory and autoimmune conditions, was found to be effective for patients in a serious condition in hospital with COVID. This discovery was the product of the RECOVERY trial, a programme started in March 2020 to find COVID treatments.
May was National Bike Month, and at the end of June this year’s Tour de France kicks off, so what better time to look at the materials science of cycling? This month’s edition of Periodic Graphics in Chemical & Engineering News looks at the various alloys and polymers used to make bike frames, tires, and accessories.
