Super volcanic eruptions interrupt ozone recovery

Since the Antarctic ozone hole was detected in 1985, depletion of the ozone layer—the "big umbrella" that protects all life on Earth—has raised considerable concern. The efforts of international communities led to the ...

On the way to printable organic light emitting diodes

Organic light-emitting diodes are components that no longer consist of compounds containing the semiconducting material gallium, but of so-called organic compounds in which carbon is a main component. Compared to conventional ...

Optimizing the growth of coatings on nanowire catalysts

Solar energy harvested by semiconductors—materials whose electrical resistance is in between that of regular metals and insulators—can trigger surface electrochemical reactions to generate clean and sustainable fuels ...

Graphenes now go monolayer and single crystalline

IBS-CMCM scientists have reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. They refined the chemical vapor deposition (CVD) growth method by eliminating all carbon impurities ...

Creating 'movies' of thin film growth

From paint on a wall to tinted car windows, thin films make up a wide variety of materials found in ordinary life. But thin films are also used to build some of today's most important technologies, such as computer chips ...
