The Limit Does Not Exist: Superheated Gold Survives the Entropy Catastrophe

It’s notoriously difficult to take the temperature of really hot things. Whether it’s the roiling plasma in our Sun, the extreme conditions at the core of planets or the crushing forces at play inside a fusion reactor, what scientists call “warm dense matter” can reach hundreds of thousands of degrees kelvin.

High Quantum Yield Material Boosts Deep Blue LED Performance

Despite the apparent brilliance of display screens that light up the world, deep blue hues are hard to come by. Now a team of scientists led by Rutgers University that includes researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has developed an approach for manufacturing light-emitting diodes (LEDs) that emit deep blue light with a wavelength of about 450 nanometers.
