AngusAlchemist Declan Fleming Tommy Technetium Now I’m hype! Draw with 405nm 🟣, erase with 630nm 🔴, no tin ions.

#LT La solution : contrairement à Li et Na avec une transition p→s émettant de la lumière du spectre visible, le potassium a une transition 4p→4s dans le domaine infrarouge. Et c'est très bien expliqué par Declan Fleming pour EiC : youtube.com/watch?v=TOyDzO… (2/n)

day totally made, thanks for sharing! Yes, we can't see the main potassium emission (youtu.be/TOyDzOc2AaI?si…) so our eyes pick up rarer emissions in the visible (also present in Li and Na but drowned out). Seeing proof of this so elegantly demoed with an IR camera is ... superbe!

4 days ago our team proposed ground-breaking, unique, new planetary observations that cannot be completed by any other spacecraft in existence. That spacecraft is soon to lose funding despite being a fully functional NASA flagship. Please help save Chandra Observatory

Our Orbyts team worked super hard in our free time to write our first Impact report based on the last 6 years of programme evaluation, so we're mega excited to share it with you: orbyts.org/impact

Amaze 11–16 learners when teaching polymers, their applications and properties with this Exhibition chemistry demonstration from Declan Fleming edu.rsc.org/exhibition-che… #scienceteachers #chemed #lunchandlearn

Recommended beer pairing 😎

protonsforbreakfast.wordpress.com/2024/05/26/tho… I tried to condense my thoughts about "Net Zero" into a 10-minute video. Tragically it came out 33 minutes long so if you want to watch it, make a cup of tea first. youtu.be/XuKTNvPUfLE

New video from UncleBob making NO2. youtu.be/5ks5NC3ddOI?fe… I need to share my own version which uses Mattson NO prep followed by addition of O2 (gives a bonus Avogadro's Law demo) Haven't got around to that because I did Avogadro's Law recently for EiC anyway! :)

I’m always happy to give talks to schools if I can make it there and back easily. But I only really get asked by private schools. If any state schools or academies want a talk about amazing, funny, inspirational science, just contact me!

Note to self: read and watch the latest Exhibition chemistry from Declan Fleming. We hear it’s lit … edu.rsc.org/exhibition-che… #teachertwitter #STEMed #chatchemistry
