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.

A New Understanding of Metastability Clears Path for Next-Generation Materials

Researchers at Lawrence Berkeley National Laboratory have published a new study that, for the first time, explicitly quantifies the thermodynamic scale of metastability for almost 30,000 known materials. This paves the way for designing and making promising next-generation materials for use in everything from semiconductors to pharmaceuticals to steels.

We Gather Here Today to Join Lasers and Anti-Lasers

Berkeley Lab scientists have, for the first time, achieved both lasing and anti-lasing in a single device. Their findings lay the groundwork for developing a new type of integrated device with the flexibility to operate as a laser, an amplifier, a modulator, and a detector.

Smallest. Transistor. Ever.

A research team led by Berkeley Lab material scientists has created a transistor with a working 1-nanometer gate, breaking a size barrier that had been set by the laws of physics. The achievement could be a key to extending the life of Moore’s Law.

Transformational X-ray Project Takes a Step Forward

A proposed upgrade to the Advanced Light Source—which would provide new views of materials and chemistry at the nanoscale with X-ray beams up to 1,000 times brighter than possible now—has cleared the first step in a Department of Energy approval process. The upgrade would enable new explorations of chemical reactions, battery performance, and biological processes.

Scientists Find Twisting 3-D Raceway for Electrons in Nanoscale Crystal Slices

Researchers have observed, for the first time, an exotic 3-D racetrack for electrons in ultrathin slices of a tiny crystal they made at Berkeley Lab.
