Chinese scientists have built the brightest extreme ultraviolet light in the world for capturing atoms and molecules that will reveal laws of the micro-material world.

"Extreme ultraviolet free-electron laser light sources are especially useful for sensitive detection of atoms, molecules and clusters as well as probing valence electronic structures of all kinds of materials," said an expert.
