For decades, the idea of engineering materials by rotating their atomic layers has tantalized physicists, yet the fragility of those layers kept the concept confined to controlled experiments. Now, researchers at North Carolina State University have found a way to stack and twist crystalline oxide membranes with strong chemical bonds across large surfaces — transforming twistronics from a laboratory curiosity into a scalable engineering platform. Published in ACS Nano, the work reveals that the bonding itself reshapes the atomic lattice at the interface, opening unforeseen structural possibili
