🔥 YOU DEFINITELY DIDN'T KNOW THIS. SPbPU scientists just watched nanocrystals grow inside glass in real time — for the first time ever. No magic, just physics and a smart optical trick. X‑rays used to be useless here: tiny crystals got lost in the glass haze. But our team tracked them via their optical "fingerprint" — from 7 to 12 nanometers. That's 10,000 times thinner than a hair! Why? To build ultra‑bright LEDs and lasers. The catch: perovskites degrade in air. But sealed inside glass, they're bulletproof. And now we can control their size — and therefore their glow color. This isn't sci‑fi. This is Polytech. And the next breakthrough? That could be you. #Priority2030
