The Heat is On

NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays at Berkeley Lab’s Advanced Light Source to test the designs.

When Rocket Science Meets X-ray Science

NASA and Berkeley Lab researchers have teamed up to explore next-generation spacecraft materials at the microscale using an X-ray technique that produces 3-D images. This work could help ensure future spacecraft survive the rigors of otherworldly atmospheres.

Three Berkeley Lab Researchers Named to National Academy of Engineering

The National Academy of Engineering named three Berkeley Lab researchers to this year’s class of 84 new members and 22 foreign associates. Robert Budnitz, Gerbrand Ceder and Katherine Yelick were elected in recognition of their distinguished and continuing achievements in original research.

Scientists Determine Precise 3-D Location and Identity of All 23,000 Atoms in a Nanoparticle

Scientists used one of the world’s most powerful electron microscopes to map the precise location and chemical type of 23,000 atoms in an extremely small particle made of iron and platinum. Insights gained from the particle’s structure could lead to new ways to improve its magnetic performance for use in high-density, next-generation hard drives.

High-Resolution Imaging Reveals New Understanding of Battery Cathode Particles

Using advanced imaging techniques, scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have been able to observe what exactly happens inside a cathode particle as lithium-ion batteries are charged and discharged. In a research project led by Berkeley Lab materials chemist Guoying Chen, the researchers uncovered important insights into reactions in

For This Metal, Electricity Flows, But Not the Heat

Berkeley scientists have discovered that electrons in vanadium dioxide can conduct electricity without conducting heat, an exotic property in an unconventional material. The characteristic could lead to applications in thermoelectrics and window coatings.

Workshop Focuses on the Unique Science Enabled by ALS-U

Visiting scientists gave input during a workshop last week on the range of new X-ray science made possible by a planned upgrade of the Advanced Light Source.

New Graphene-Based System Could Help Us ‘See’ Electrical Signaling in Heart and Nerve Cells

Scientists have enlisted the exotic properties of graphene to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields. They hope to enlist the new method to image electrical signaling networks in our hearts and brains.

Glowing Crystals Can Detect, Cleanse Contaminated Drinking Water

Motivated by public hazards associated with contaminated sources of drinking water, a team of scientists has successfully developed and tested tiny, glowing crystals that can detect and trap heavy-metal toxins like mercury and lead.

Scientists Trace ‘Poisoning’ in Chemical Reactions to the Atomic Scale

A combination of experiments, including X-ray studies at Berkeley Lab, revealed new details about pesky deposits that can stop chemical reactions vital to fuel production and other processes.
