Transparent Aluminium Created

Description

Oxford scientists have created a transparent form of aluminium by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminium' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion.


In the journal Nature Physics an international team, led by Oxford University scientists, report that a short pulse from the FLASH laser 'knocked out' a core electron from every aluminium atom in a sample without disrupting the metal's crystalline structure. This turned the aluminium nearly invisible to extreme ultraviolet radiation.
