If you want to know more about the science behind it, I worked with @climate_adam on this video he did about how greenhouse gases work a few years back:

Did you know that the gases in one tiny blue asthma inhaler can cause as much global heating as 30kg of CO2? You can read all about it in my latest @ChemistryWorld story at https://t.co/VFOnQn4NLB.

If you are not already awestruck about the fact that chemists can follow processes on the infinitesimally small femtosecond scale I hope you will be after watching this! Then if you’re interested read my @ChemistryWorld story at https://t.co/KI6kkxGxNa Thanks to @ListNanna et al!

t's part of a general trend towards falling emissions in China, which you can also read about at https://t.co/NKqlG0wLdD and

Clean-energy growth helped China’s CO2 emissions fall by 1% in first half of 2025, extending a declining trend that started in March 2024.

Easy to make and versatile enough to go on everyday devices, perovskite solar cells are hampered by poor stability and lead toxicity. It should be possible to cheaply and cleanly recycle them, which enhances their chances of commercial success. By me:

Mainly water-based approach is also cheaper than using new starting materials

I was today years old when I discovered pure calcium metal can be a bit yellowy. I have seen a photo that looks yellow and is apparently 99.999% pure but is copyrighted so I can't share it. Most online photos of calcium don't look yellow. Anyone know the scientific reason why?

Chemistry friends! Do you use AI in your current/recent role? 💻 If so, please tell me: ⚒️ What tools do you use? 🛠️ How do you use them? 🔨 Do you rely on them? 💡 Do you consider them transformational? 🤔 How do you gauge whether it's worth your time investigating a new tool?

Once again terrible customer service. No phone connection, offices closed, web help form only returns an error. Happy Christmas @EcotalkMobile!
Having a terrible customer service experience with @EcotalkMobile. Having received no correspondence from them, they just called, said I hadn't paid my bill, asked for a bunch of personal details, then cut off my mobile service when I refused to give them. Now I can't reach them!

Dialogue with Andy Extance writing about compostable plastic in @ChemistryWorld @ChemistryOpen @CNRsocial_
chemistryworld.com
Rather than a potential triumph, the compostable plastics we use look increasingly like a tragedy. Andy Extance looks at the problems and seeks solutions

'The decision represents a striking change in MDMA’s trajectory,' writes @andyextance. 'Back in 2017, the FDA had granted the drug an expedited review process.' https://t.co/UFBRNtiuOK
