Researchers stumble onto 'lava' generated quantum dots, could power future peripherals

Have you ever been playing around with molten metal salt, when you accidentally created hollow, soft-shelled particles that could one day increase hard disk storage or power future QLED displays? Us neither, but that's exactly what happened to scientists at Rice University when they were researching "tetrapods" to make solar panels more efficient. Through an apparently wacky coincidence, they removed a single ingredient from the tetrapod stew, which left behind tiny droplets of cadmium nitrate. ...
