Transforming e-waste into a strong, protective coating for metal

A typical recycling process converts large quantities of items made of a single material into more of the same. However, this approach isn't feasible for old electronic devices, or 'e-waste,' because they contain small amounts ...

New insights into the energy levels in quantum dots

Researchers from Basel, Bochum, and Copenhagen have gained new insights into the energy states of quantum dots. They are semiconductor nanostructures and promising building blocks for quantum communication. With their experiments, ...

'Tickling' an atom to investigate the behavior of materials

Scientists and engineers working at the frontier of nanotechnology face huge challenges. When the position of a single atom in a material may change the fundamental properties of that material, scientists need something in ...

First view of hydrogen at the metal-to-metal hydride interface

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the ...

Tiny quantum sensors watch materials transform under pressure

Since their invention more than 60 years ago, diamond anvil cells have made it possible for scientists to recreate extreme phenomena—such as the crushing pressures deep inside the Earth's mantle—or to enable chemical ...

Researchers set new upper limit on neutrino mass

An international team of researchers has used a new spectrometer to find and set an upper limit for the mass of a neutrino. In their paper published in the journal Physical Review Letters, the group describes how they came ...

Scientists unravel mysteries of cells' whiplike extensions

Cilia, or flagella—whiplike appendages on cells—perform diverse tasks required to keep the body healthy. When cilia malfunction, the consequences can be devastating, causing a range of problems, from blindness, to lung ...
