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 »PPT-icon-35 PDF-icon-35

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.

The operating schedule for the 2025-1 cycle (January-July 2025) has been posted. The next long shutdown will begin in January 2025 and is expected to last 11 weeks. The most up-to-date information on the current schedule and future outlook can always be found on the Operating Schedule web page. Read more »

Magnetization Switching in Highly Magnetostrictive Microstructures

Researchers learned how the size, shape, and orientation of microstructures affect how they switch magnetization directions in response to an applied voltage. The work advances our understanding of strain-responsive composite materials for use in energy-efficient electronic applications such as memory devices, sensors, and actuators.
