A study on the remarkable durability of 2000-year old Roman concrete, by ALS user Marie Jackson with ALS beamline scientist Nobumichi Tamura, was recently highlighted in “Miracle Materials,” a science documentary produced by a German-French company, Gruppe 5, for airing on the Eurpean public service channel, ARTE.

Case study evaluation of size-resolved molecular composition and phase state of carbonaceous particles in wildfire influenced smoke from the Pacific Northwest
Wildfires are significant sources of carbonaceous particles in the atmosphere. Given the dependence of atmospheric processes on particle physical and molecular properties, the interplay between particle size, phase state and chemical composition is investigated here for aerosols influenced by a 2021 Pacific Northwest wildfire event.

Electronic transport and polarization-dependent photoresponse in few-layered hafnium trisulfide (HfS3) nanoribbons
We report on the electrical and optoelectronic characterization of field-effect transistor (FET) devices based on few-layered HfS3 nanoribbons. The results support the contention that in the presence of light, the photocarriers include both electrons and holes, enhancing the photocurrent of devices. Read more »
Making Renewable, Infinitely Recyclable Plastics Using Bacteria
Scientists engineered microbes to make the ingredients for recyclable plastics—replacing finite, polluting petrochemicals with sustainable alternatives. The new approach shows that renewable, recyclable plastics are not only possible, but also outperform those from petrochemicals. Read more »
Catching up with ASPIRES Interns from 2022 and 2023
The ASPIRES program is a 10-week paid internship matching undergraduate students from California State East Bay with mentors in Berkeley Lab’s Energy Sciences Area. We caught up with some of the ASPIRES interns from 2022 and 2023 to hear about their internship experience and what they’re working on! Read more »
2023 User Meeting Registration Now Open

To help us allocate space, please register early and indicate the sessions you’re interested in attending. Read more »
Capturing the Spin Dynamics of a Complex Magnetic Material
Magnetic iron oxides (ferrites) are complex materials with broad electronic applications that are often driven by microwaves. Here, researchers have precisely measured the spin behavior of several distinct cations in a ferrite material under an applied microwave field, validating a longstanding assumption about magnetic oxide dynamics.

September 6 Deadline for General User Proposals
The User Office is accepting new General User Proposals (GUPs) from scientists who wish to conduct research at the ALS in the 2024-1 (January–July) cycle. The deadline for submissions is September 6, 2023. Applicants are reminded that they may request joint access to the Molecular Foundry, a nanoscience user facility at Berkeley Lab, to support their ALS activities. Read more »
Greetings from New ALS Director Dimitri Argyriou
ALS Director Dimitri Argyriou, who arrived this month, is excited to join the vibrant community at our facility. He invites everyone to participate in this strongly collaborative environment and shape the future of the ALS. Read more »
A New Pathway for Clearing Misfolded Proteins
Researchers integrated several approaches, such as cryogenic 3D imaging at the ALS, to define a novel cellular pathway—involving a shared “garbage dump”—for clearing misfolded proteins from cells. The pathway is a potential therapy target for age-related diseases like Alzheimer’s, Huntington’s, and Parkinson’s diseases. Read more »
