This week (12-18 November) is #RealTimeChem Week! For the unaware, #RealTimChem is a chemistry community on Twitter that encourages chemists to tweet about their chemistry. As in previous years, I put together the banners to promote this year’s event which has the theme #Chem4Life. As part of it, chemists in the community will be celebrating the chemistry you come across every day – so it’s worth checking out even if you’re not a chemist yourself!
