Three RIKEN physicists have discovered how tiny tubes of carbon spit out light that is more energetic than the light shone on them. This finding could help to exploit the process in applications such ...

The carbon nanotubes reported here were seen in cathodic deposits produced by arc-discharge of graphite rods in a hydrogen atmosphere without a metallic catalyst 6. Under these conditions ...

Lithium-ion batteries have long reigned as the champions of portable energy, propelling the tech industry forward with their robust energy storage capabilities. However, the quest for alternatives ...
