Warren Byrne, Principal Scientific Engineering Associate
We sat down recently with Principal Scientific Engineering Associate Warren Byrne to get his take on the history and future of the ALS, from an accelerator point of view. Byrne came to the ALS as it was being built in 1992, starting out in the operations group and then moving into the accelerator physics group. For the past 16 years, he has been in charge of overseeing the injector system, which consists of the linac and the booster synchrotron and the electron gun. Read more »
ALS, Molecular Foundry, and aBeam Technologies Collaborate to Make Metrology History
A collaboration between Bay Area company aBeam Technologies, the ALS, and the Molecular Foundry is bringing cutting-edge metrology instrumentation to the semiconductor market, which will enable a new level of quality control. Read more »
2015 ALS User Meeting Highlights
The 2015 User Meeting brought together 405 ALS users from around the world, many of whom shared insights and sparked discussion with presentations of their ALS research highlights. Read more »
Footprinting Technique Gives ALS Users New Insights
The x-ray footprinting (XFP) technique developed at ALS Beamline 5.3.1 gives researchers a powerful tool for the study of macromolecular structures and dynamics of proteins and nucleic acids in solution. Read more »
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.
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.

Ligand Noninnocence in Coinage Metal Corroles: A Silver Knife-Edge
In contrast to noninnocent copper corroles and essentially innocent gold corroles, silver corroles appear to be poised on a knife-edge between the two electronic-structural descriptions. The summit trail of Mount Sir Alexander, a peak of the Canadian Rockies described by mountaineer Chris Goulet as a knife-edge that only a mouse can walk on, provides anRead More Read more »
Reminiscences of Bob Miller
Bob Miller passed away in October after a brief illness. He was a well-loved member of the ALS community, and even after his retirement in 2000, he was always around for advice and social events. He was well known for his love of the outdoors and for his passion for remote-controlled planes and boats. Memories fromRead More Read more »
Mono- and Diboron Corroles: Factors Controlling Stoichiometry and Hydrolytic Reactivity
The synthesis and structural characterization of a diboryl triaryloctabromocorrole complex fills in a missing link in the family of diboron porphyrinoids. DFT calculations suggest that a strongly electron-withdrawing corrole ligand is required to stabilize the diboryl complex relative to the partially hydrolyzed diboron corrole complexes previously observed. New monoboryl corrole complexes are described, which do not have counterparts in porphyrin chemistry and are stabilized by internal F···H hydrogen bonding. Read more »
