The spintronics technology revolution could be just a hopfion away

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

A research team co-led by Berkeley Lab has created and observed quasiparticles called 3D hopfions at the nanoscale (billionths of a meter) in a magnetic system. The discovery could advance high-density, high-speed, low-power, yet ultrastable magnetic memory "spintronics" devices.

The incredible bacterial 'homing missiles' that scientists want to harness

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Imagine there are arrows that are lethal when fired on your enemies yet harmless if they fall on your friends. It's easy to see how these would be an amazing advantage in warfare, if they were real. Well, something just like these arrows does indeed exist, and they are used in warfare ... just on a different scale. These weapons are called tailocins, and the reality is almost stranger than fiction.

Designing selective membranes for batteries using a drug discovery toolbox

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

A research team led by Berkeley Lab has developed a lithium-selective polymer membrane that could allow high-voltage battery cells to operate at higher power and more efficiently, important factors for both electric vehicles and aircraft.

Dark Energy Survey physicists open new window into dark energy

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

An analysis by Dark Energy Survey physicists yields more precise estimates of the average density of matter as well as its propensity to clump together - two key parameters that help physicists probe the nature of dark matter and dark energy.

Revealing nano big bang -- Scientists observe the first milliseconds of crystal formation

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

At the Molecular Foundry, scientists recruited a world-leading microscope to capture atomic-resolution, high-speed images of gold atoms self-organizing, falling apart, and then reorganizing many times before settling into a stable, ordered crystal.

Scientists uncover a process that stands in the way of making quantum dots brighter

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots' light-producing efficiency. A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example.

Do you know the way to Berkelium, Californium?

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists at Berkeley Lab have demonstrated how to image samples of heavy elements as small as a single nanogram. The new approach will help scientists advance new technologies for medical imaging and cancer therapies.
