China has tightened control over the global rare earth supply by introducing new export restrictions that could disrupt industries dependent on these materials. The latest measures, announced late last week, target seven elements – including scandium and dysprosium – used in smartphones, electric vehicles, and military tech. Rather than a blanket ban, the rules require exporters to obtain licenses and specify how buyers intend to use the materials, creating bureaucratic friction that could delay

“Perovskite LEDs are cheaper and easier to manufacture than traditional LEDs, and they can also produce vibrant and intense colours if used in screens. I’d say that this is the next generation of LED technology,” says Feng Gao, professor of optoelectronics at Linköping University. However, for a technological shift to take place, where today’s LEDs are replaced with those based on the material perovskite, more than just technical performance is required.

When mechanical and structural engineers design machines, bridges, and buildings, they calculate loads, stresses, and deformation of metal, steel, concrete, glass, wood, and plastic to find the optimal geometry that bears loads with the minimum cost of material. Designing for relatively hard materials that do not deform too much is commonly handled by software that calculates and optimizes structures using mathematical models that are well understood and easily applied.
