ALS X-Rays Shine a New Light on Catalysis

Recently a team of Stanford and Berkeley Lab researchers used x-rays at the ALS in a novel way to observe the behavior of electrons during technologically important chemical reactions in metal oxide electrocatalysts. What they learned has upended long-held scientific understanding of how these catalysts work. Read more »PPT-icon-35 PDF-icon-35

Takeda Advances Diabetes Drug Development at the ALS

Type 2 diabetes mellitus (T2DM), characterized by abnormally high blood glucose levels, affects hundreds of millions of people worldwide. In the pursuit to better treat this disease, the human receptor protein GPR40 has been identified by pharmaceutical company Takeda as a potential new drug target.

Moore Foundation Funds ALS Researchers for Promising New Technique for Studying Materials

A novel x-ray scattering concept by researchers at Lawrence Berkeley National Laboratory’s (Berkeley Lab) Advanced Light Source (ALS) is receiving support from the Gordon and Betty Moore Foundation in the amount of $2.4 million. The grant was awarded in April by the foundation. The lead investigator on the effort will be ALS Division Deputy Zahid Hussain with ALS Director Roger Falcone acting as co-PI on the project.

A Fullerene that Breaks the Rules

Scientists used small-molecule x-ray crystallography to verify and characterize the first non-functionalized fullerene with a heptagonal ring in the cage. This new molecule changes the definition of a classical fullerene and expands the range of structural possibilities for endohedral fullerenes. Read more »PPT-icon-35 PDF-icon-35

Elaine Chan Fosters ALS/Molecular Foundry Collaboration

In an ongoing effort to build closer working relationships between Berkeley Lab’s light source and nanoscale science research center, Elaine Chan has recently been appointed by the ALS and the Molecular Foundry to a new role as joint ALS/Foundry project scientist. Chan’s mission will be to foster collaborations between the two facility’s users and to communicate a wider understanding about how the two research centers are mutually scientifically beneficial.

Notification of General User Proposal and Approved Program Results

The Proposal Study Panel (PSP) met April 23–24 to oversee and finalize the scoring of General User Proposals for the 2015-2 operating cycle, and to make recommendations to the ALS Scientific Advisory Committee (SAC) on Approved Program applications. Allocation meetings for each beamline will take place in May. Read more »

2015 ALS Shutdown

The upcoming long-term operating schedule has been published and users will note that it includes an extended shutdown period (October 26, 2015-January 13, 2016) for the ALS. The lengthy shutdown is in part because it spans the Thanksgiving and Holiday shutdown periods, as well as being indicative of the amount of time required to implement major upgrades. The main project for this shutdown is the completion of the final phase of the Storage Ring Radio Frequency (SRRF) Upgrade. Read more »

Peptoid Nanosheets Offer a Diversity of Functionalities

Researchers at the ALS have recently observed peptoid nanosheets as they self-assemble at an oil–water interface. This development opens the door to designing peptoid nanosheets of increasing complexity and functionality for a broad range of applications, including improved chemical sensors and separators, and safer, more effective drug-delivery vehicles.
