Absolute vs. relative efficiency: How efficient are blue LEDs, actually?

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study from University of Illinois Urbana-Champaign ...

Temperature of solar flares helps understand nature of solar plasma

The sun's rotation produces changes in its magnetic field, which flips completely every 11 years or so, triggering a phase of intense activity. Solar flares—huge eruptions from the surface of the sun lasting minutes or ...

Study: Smoke particles from wildfires can erode the ozone layer

A wildfire can pump smoke up into the stratosphere, where the particles drift for over a year. A new MIT study has found that while suspended there these particles can trigger chemical reactions that erode the protective ...
