Researchers at the University of Surrey's Advanced Technology Institute manipulated zinc oxide, producing nanowires from this readily available material to create a ultra-violet light detector which is 10,000 times more sensitive to UV light than a traditional zinc oxide detector. Currently, photoelectric...

Improving energy efficiency one atom at a time
Paul Simmonds looks at his molecular beam epitaxy (MBE) system the way other guys do a candy apple red Porsche. The sci-fi looking machine used to design and create new materials at the atomic level lights his eyes with pure joy. MBE is a cutting-edge technique that allows for the design and creation of completely new materials that don’t exist in...
Quantum glue
Even a perfect vacuum is not truly empty. If you could observe that vacuum on the quantum, atomic or subatomic scale, you would see a “bubbling soup” of "ghost" particles. Known as “virtual particles,” they randomly pop in and out of existence in the empty space; and they cause a phenomenon known as vacuum fluctuation. So, in a space that is completely...
