An international team of researchers has developed a breakthrough method for producing MXenes—an important family of two-dimensional materials—with unprecedented purity and control. The new "gas–liquid–solid" process enables the synthesis of pure MXenes with uniformly distributed halogen ato ms on the surface and a precisely tunable surface composition. The method dramatically boosts their electrical conductivity and opens the door to high-performance electronics, sensors, and energy technologies. ...read more read less
