Scientists have identified several avenues by which ringed molecules known as polycyclic aromatic hydrocarbons can form in space. PAHs—which also occur on Earth in emissions and soot from the combustion of fossil fuels—could provide clues to the formation of life’s chemistry in space as precursors to interstellar nanoparticles.

The Chemistry of Art
To learn more about the chemical processes involved in aging oil paints in microscopic and nanoscale detail, researchers conducted a range of studies that included 3D x-ray imaging of a paint sample. The study could have broader implications for conservation based on the observed chemistry of oil paints. Read more »
Chemical and Morphological Origins of Improved Ion Conductivity in Perfluoro Ionene Chain Extended Ionomers
Resonant x-ray scattering and x-ray absorption spectroscopy with elemental sensitivity unravel structural features tied to water–ion domains and discern sulfur-containing groups in sulfonated ionomers, which help delineate chemical factors controlling their phase-separated morphology and governing ion transport.

SSURF Sponsors Congressional Visit to Bay Area User Facilities
The Society for Science at User Research Facilities (SSURF) sponsored a delegation of Congressional staffers to visit national user facilities in the Bay Area this week. On Tuesday, they stopped by the ALS to learn about our capabilities and scientific impact first-hand. Interested in volunteering to support SSURF and its mission to provide a consolidated voice for those interested in research conducted by users of U.S. national user facilities? Contact ALS Communications Director and SSURF Board Member Ashley White (awhite@lbl.gov) to learn more.
LAAAMP Brings International Researchers to the Advanced Light Source
This summer, the ALS hosted researchers from Mexico and Egypt as part of LAAAMP—Lightsources for Africa, the Americas, Asia and Middle East Project. Their studies on solar cells and mummy bones exemplify the benefit of increasing access to synchrotron-enabled research. Read more »
Curtis Gomez, Electrical Safety Officer
Curtis Gomez recently became the ALS electrical safety officer. Besides looking out for hazards, his work in motor controls coordination draws from a TV and radio background—and working for a local band that made it big. Read more »
Microelectronics Town Hall Looks Beyond Moore’s Law
On August 16, Berkeley Lab hosted a town hall on future research and collaboration opportunities in microelectronics—a deceptively simple catchword that encompasses the full range of integrated developments needed to push beyond Moore’s Law. Eli Rotenberg gave one of several short talks about how the ALS fits into this effort. Read more »
ALS Provides Immersive Experience for Summer Interns
High school and undergraduate students don’t usually get a lot of real-world programming and hardware development experience, especially not with things like neural networks and synchrotron light source beamline components. Eighteen students got thrown into the deep end with these topics during their internships at the ALS. Read more »
Facility News and Shutdown Recap: Summer 2019
It’s been a busy summer at the ALS, with developments ranging from the delivery of a new prototype magnet for testing, to the refurbishing of the Building 80 cubicle farm and lounge area. A five-week shutdown checked off several important upgrades and installations, while other Building 6–related projects proceeded in parallel. Read more »
Infrared Nano-Mapping of Local Strain in 2D Materials
Researchers have demonstrated an infrared technique to map and analyze strain in atomically thin crystals of hexagonal boron nitride (hBN) at the nanoscale. This ultrasensitive strain-imaging method could be a promising tool for the examination of low-dimensional materials of interest for electronic and photonic devices. Read more »
