Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light.


Word of the Day
upstander
  • A person who stands up for something, as contrasted to a bystander who remains inactive.
  • One of the upright handlebars on a traditional Inuit sled.
The word 'upstander' in the first sense here is a play on the word 'bystander' and the idea of 'standing up' for something.
