How a New Electrocatalyst Enables Ultrafast Reactions
With key data from the ALS, researchers discovered how a new, low-cost electrocatalyst enables an important oxygen reaction to proceed at an ultrafast rate. The work provides rational guidance for the development of better electrocatalysts for applications such as hydrogen-fuel production and long-range batteries for electric vehicles. Read more »
Stefania Trovati, Lead Radiation Physicist
As the lead radiation physicist at the ALS, Stefania Trovati is an expert in characterizing the radiation environment, but her expertise stretches beyond physics. She is also highly knowledgeable about raccoons and many other animals. Read more »
Criegee Intermediates Play Unexpected Role in Cell Chemistry
Researchers employed mass spectrometry to illuminate lipid nanodroplets under ultraviolet light. The results unexpectedly showed that hydroxyl radicals cause damage to cells via the formation of Criegee intermediates: molecules first proposed in 1975 to explain how pollutants react with the ozone layer in our atmosphere.

Elusive Kagome Electronic Structures Revealed
Electronic-structure studies showed that both infinitely light and infinitely massive particles coexist in a material with a star-shaped (kagome) crystal lattice. The material’s rich array of electronic behaviors shows promise for future spintronic applications and represents a new frontier for studying exotic phases of matter. Read more » 
A Graphene Innovation That Is Music to Your Ears
A California-based company called GraphAudio is moving toward commercializing graphene-based audio technology developed by researchers at Berkeley Lab and UC Berkeley. The technology could transform a variety of devices, including speakers, earbuds and headphones, microphones, autonomous vehicle sensors, and ultrasonic and echolocation systems. Read more »
Blending Ionic and Coordinate Bonds in Hybrid Semiconductor Materials: A General Approach toward Robust and Solution-Processable Covalent/Coordinate Network Structures
Blending ionic and coordinate bonds in copper iodide based hybrid semiconductor materials with extended covalent/coordinate network structures leads to greatly enhanced solubility and solution processability, making it possible to form high-quality films for device fabrication. Read more »
X-ray Crystal Structures of the Influenza M2 Proton Channel Drug-Resistant V27A Mutant Bound to a Spiro-Adamantyl Amine Inhibitor Reveal the Mechanism of Adamantane Resistance
The M2 proton channel, shown with front and back monomer helices removed, is an anti-influenza drug target. Here, a bound inhibitor blocks the transport of protons through the V27A mutant channel. Read more »
Scientists Discover New Clue Behind Age-Related Diseases and Food Spoilage
Scientists at Berkeley Lab have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time. The findings point to an unexpected link between the ozone chemistry in our atmosphere and our cells’ hardwired ability to ward off disease. Read more »
Highly Permeable Perfluorinated Sulfonic Acid Ionomers for Improved Electrochemical Devices: Insights into Structure-Property Relationships
Perfluorinated sulfonic acid ionomers (PFSAs) induce significant mass-transport limitations in proton exchange membrane fuel cell catalyst layers due to their semicrystalline PTFE-based matrix. We present a novel PFSA with an amorphous perfluorinated matrix, which vastly improves gas permeability, reduces transport resistance, and improves catalyst utilization in functional catalyst layers.
