Collecting light with artificial moth eyes

All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a photoelectrochemical ...

Electron beam melting gets brittle metal into shape

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion ...

Probing the dynamics of photoemission

Almost a century ago, Albert Einstein received the Nobel Prize for Physics for his explanation of the photoelectric effect. Published in 1905, Einstein's theory incorporated the idea that light is made up of particles called ...

New property of flames sparks advances in technology

Chemists at UCL have discovered a new property of flames, which allows them to control reactions at a solid surface in a flame and opens up a whole new field of chemical innovation.

Tungsten may not be the best shot for making 'green' bullets

With efforts underway to ban lead-based ammunition as a potential health and environmental hazard, scientists are reporting new evidence that a prime alternative material for bullets — tungsten — may not be a good ...
