Massive congrats to Arjun’s & Raj on this heroic effort (and thanks for letting us join for a tiny part of the journey) now out in 𝙉𝙖𝙩𝙪𝙧𝙚 @nature.com ! We found optically-active magnetic edges in phosphorene nanoribbons, promising for #quantum #electronics www.nature.com/articles/s41...

I have started a list of scientists who research perovskite materials for solar cells. The key word here is started. Please help me find everyone who is on here who I have missed! Nominate yourself, point me to people who are missing, let's fill that list! 🧪

An amazing #MATSUS25 week in beautiful Seville came to an end. Massive thank you to all organizers, esp. the Light emission and Quantum symposia ones for inviting! Lots of fun as usual catching up with the #community broadly in a place so vibrant and full of history! :) @nanoge.org

☕Time for coffee at #MATSUS25 after exploring the potential of I-III-VI semiconducting nanocrystals, novel lead-free perovskite materials, recycling strategies of perovskite-based solar cells and much more. 🔗Visit the website to discover more topics: https://www.nanoge.org/MATSUSSpring25/home
