A collaborative effort between Professor Sun Jian's team at the School of Physics, Nanjing University, and international researchers has unveiled a novel atomic arrangement within graphene interlayers. This discovery challenges the conventional wisdom that simple elements like helium exclusively exist in "closest-packed structures" and sheds light on the transformative principle governing matter's evolution from two-dimensional to three-dimensional states. The groundbreaking findings have been featured in the Proceedings of the National Academy of Sciences.
