How computing is transforming materials science research

In the United States, the start of 2014 marked the end of an era—the "death" of incandescent light bulbs. Not that all 40- and 60-watt incandescent light bulbs simultaneously stopped working on January 1, 2014, but their ...

LEDs: Better red makes brighter white

Chemists at Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a novel type of red phosphor material, which significantly enhances the performance of white-emitting LEDs.

Cooking up new nanoribbons to make better white LEDs

As the world moves away from incandescent light bulbs, light-emitting diodes (LEDs) are growing in popularity. They use significantly less energy and have far longer lifetimes than do the traditional incandescent bulbs, which ...

Home electricity use in US falling to 2001 levels
