A new study led by researchers at Berkeley Lab outlines a way to engineer pseudo-bonds in materials. Instead of forming chemical bonds, which is what makes epoxies and other composites so tough, the chains of molecules entangle in a way that is fully reversible. Read more »
A Clearer Look at Lithium-Ion Traffic Jams in Batteries
By directly visualizing the uneven insertion of lithium ions into electrodes with well-defined crystal orientations, researchers learned why fast charging decreases battery lifespan and performance. The work could provide insights into better battery utilization and help investigations of the surface insertion reaction during fast charging. Read more »
Bennu’s Ancient Brine Sheds Light on Recipe for Life
Researchers traced the evolution of minerals (“salts”) in an ancient brine, as recorded in samples from the asteroid Bennu, returned to Earth by NASA’s OSIRIS-REx mission. The results support the idea that asteroids like Bennu may have delivered water and essential chemical building blocks of life to Earth in the distant past. Read more »

Berkeley Lab Helps Explore Mysteries of Asteroid Bennu
The Advanced Light Source and Molecular Foundry provided powerful tools to study asteroid samples returned by NASA’s OSIRIS-REx mission to the asteroid Bennu. Researchers found a telltale set of salts formed by evaporation that illuminate Bennu’s watery past. Read more »

Native American Interns Explore Engineering Opportunities at the Lab
This last summer, Berkeley Lab hosted three students from Navajo Technical University in a DOE-funded initiative that partners national labs with learning institutions whose populations are historically underrepresented in science. The goal is to increase enrollment of Native American students in Navajo Tech engineering programs. Read more »
Not All Gaps Are Created Equal
Researchers found that charge density waves (CDWs) in topological materials induce unconventional spectral gaps in the materials’ electronic structure. The finding that CDWs in topological materials can be essentially different from that in other materials should be carefully considered when designing quantum devices. Read more »
A Macromolecular Scaffold for Probing Actinium Chemistry
By encapsulating actinium atoms within a macromolecular complex for analysis using protein crystallography, researchers discovered that actinium has a unique solid-state bonding configuration. A better understanding of actinium behavior could help improve a promising cancer treatment known as targeted alpha therapy. Read more »
Lattice-Dependent Spin Textures in High-Tc Superconductors
Researchers found that in bismuth-based cuprate superconductors, charge imbalances caused by lattice distortions generate persistent and universal patterns of spin polarization. The results supply a previously missing but essential ingredient in efforts to understand the mechanisms driving the electronic behavior of high-temperature superconductors. Read more »
