Welcome to another edition of the Ci newsletter, this time featuring dandelion tyres, cheese and milk chemistry, 3D-printed ion block resources, and more! I have to kick off with apologies for the disruption to the usual schedule, with the last newsletter coming a month ago. Some of you may know that my day job is at an exam board here in the UK, and oh boy has it been busy. Thankfully, things are now a little less frantic, so I'm hoping to get back to regular newsletters (and posting to the various Ci social media channels, which have also been a bit neglected over the past month). Hopefully you haven't missed your regular doses of chemistry graphics too much!
