New Spectroscopic Technique Could Accelerate the Push for Better Batteries

A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications. The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode.

Remembrances of Things Past: Berkeley Lab Researchers Discover Nanoscale Shape-Memory Oxide

Berkeley Lab researchers have discovered a way to introduce a shape memory effect in bismuth ferrite that is larger than any observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.

Overcoming Brittleness: New Insights into Bulk Metallic Glass

Berkeley Lab researchers have found a bulk metallic glass based on palladium that’s as strong as the best composite bulk metallic glasses and comparable to steel, aluminum and titanium.

Taking a New Look at Carbon Nanotubes

Two of the biggest challenges in carbon nanotube research have been met with the development by Berkeley Lab researchers of a technique that can be used to identify the structure of an individual carbon nanotube and characterize its electronic and optical properties in a functional device.

Of Fish Scales and Adaptable Armor – The Things That X-Rays Can Tell You

X-ray beams from Berkeley Lab’s Advanced Light Source uncovered the secret behind the scales of a fish tough enough to withstand piranha bites.

Diamond Imperfections Pave the Way to Technology Gold

Using ultrafast 2D electronic spectroscopy, Berkeley Lab researchers have recorded unprecedented observations of energy moving through the atom-sized diamond impurities known as nitrogen-vacancy (NV) centers. Their results provide information on NV centers that is important for such highly promising advanced technologies as supersensitive detections of magnetic fields and quantum computing.

“Molecular Velcro” May Lead to Cost-Effective Alternatives to Natural Antibodies

Taking inspiration from the human immune system, researchers at Berkeley Lab have created a new material that can be programmed to identify an endless variety of molecules. The new material resembles tiny sheets of Velcro, each just one-hundred nanometers across. But instead of securing your sneakers, this molecular Velcro mimics the way natural antibodies recognize viruses and toxins, and could lead to a new class of biosensors.
