time again! Follow along in this thread every day, kicking off with the molecules behind the piney scent of Christmas trees 🎄
Here's a thread highlighting all of the amazing women featured in these

cards. I'll continue to add to this thread as I add to the series over the coming weeks and months! 🧵⬇️
#Thunderstorms
are forecast in the UK over the coming days – here’s how thunder and lightning happen and some of the chemistry going on during a storm:
The 2023 Nobel Prize in Chemistry was awarded for the discovery and synthesis of quantum dots, small particles with big colours. Here's a summary of this prize-winning research and its applications:
"Pepper spray is not a chemical irritant. It's not chemical" -- AG Barr uses painstaking distinctions to defend the use of force against protesters near the White House last Monday

#AdaLovelaceDay
– celebrating the achievements of women in science. Here are a series of graphics highlighting women in chemistry from the past and the present:
Today is the autumn equinox in the northern hemisphere, so here's a look at the chemical cause of the yellows, oranges and reds in the fall foliage we'll be seeing shortly!
The 2021
#NobelPrize
in Chemistry was awarded for the development of asymmetric organocatalysis, the use of small organic molecules to make mirror image molecules cheaply and efficiently:
Tomorrow it’s the International Day of Women and Girls in Science 👩🏼🔬 I made this graphic a few years back highlighting contemporary women in chemistry – any you’d like to see added in a second edition?

#WorldChocolateDay
! These graphics look at the chemical differences between different types of chocolate, and how the chocolate's properties can differ at different temperatures 🍫
Did you know that this year's Olympic medals are the first to be made solely from recycled metals? 🥇🥈🥉
The metals were scavenged from 78,905 tons of electronic devices, including 6.21 million mobile phones ♻️📱

#MoleDay
– celebrating the mole in chemistry which makes it easier to talk about the huge numbers of atoms, molecules or ions that participate in chemical reactions (nothing to do with the burrowing mammals). More mole material here:
Dmitri Mendeleev was born
#OTD
in 1834. He published a periodic table which ordered the elements by increasing relative atomic mass and left gaps for undiscovered elements.
An RNA vaccine produced by Pfizer & BioNTech was approved for use in the UK today.
Here's a graphic, made with

in the UK today! While lockdown might mean you can’t make it to a fireworks display, you can still learn about the chemistry behind the colours with this poster 🎇
Did you know you can make a spooky fluorescent extract from pumpkin seeds? Crushing them with nail varnish remover gives an extract that glows red-orange in UV light, thanks to the chlorophyll precursor protochlorophyllide 🎃 HT

Margaret Dayhoff, a pioneer in the field of bioinformatics, was born
#OTD
in 1925. She developed the one-letter code used for amino acids, to reduce the size of the data files needed to describe the sequence of amino acids in a protein.
Today's Google Doodle celebrates the 225th birthday of Friedlieb Ferdinand Runge, who was the first person to isolate caffeine from coffee beans:
