New instrument unravels landscape longevity

How many years can a mountain exist? Bob Dylan's rhetorical question has just received yet another scientifically based answer. Researchers from Wageningen University & Research (WUR) and Denmark's Technical University (DTU) ...

Making a movie of nanocrystal structural evolution

When you rapidly turn the pages of a flipbook, the series of static images look like they are moving. Scientists recently applied a similar principle to capture how the structure of a material changes over extremely short ...

Electrons slowing down at critical moments

In a new study, researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory have determined that electrons in some oxides can experience an "unconventional slowing down" of their response to a light ...

Why perovskite solar cells are so efficient

Solar cells with efficiencies above 20% and produced at low costs – perovskites make this possible. Now, researchers of Karlsruhe Institute of Technology (KIT) have gained fundamental insight into the function of perovskite ...

En route to the optical nuclear clock

The nucleus of thorium-229 possesses a property that is unique among all known nuclides: It should be possible to excite it with ultraviolet light. To date, little has been known about the low-energy state of the Th-229 nucleus ...

From insulator to conductor in a flash

In recent decades, computers have become faster and hard disks and storage chips have reached enormous capacities. But this trend cannot continue forever. Physical limits are preventing silicon-based computer technology from ...
