A Deep-Learning Analysis of Lithium-Plating Dynamics in Batteries

Lithium-metal solid-state batteries are a promising technology, but the deposition (plating) of lithium metal on electrode surfaces remains a significant technical hurdle. Here, researchers used micro-computed tomography data to train an artificial intelligence model to identify characteristics vital to improving battery performance. Read more »PPT-icon-35

UEC Nominations Due October 27, 2023

The Advanced Light Source Users’ Executive Committee (UEC) invites nominations for its upcoming election for three new UEC members (2024–2026 term). Nominations will be accepted through Friday, October 27, 2023. Take a look at what is involved, and remember that self-nominations are welcome! Read more »

Accelerating Sustainable Semiconductors With ‘Multielement Ink’

Scientists have developed “multielement ink”—the first “high-entropy” semiconductor that can be processed at low temperature or room temperature. The new semiconducting material could accelerate the sustainable production of next-gen microelectronics, photovoltaics, solid state lighting, and display devices. Read more »

Haris Mahic, Accelerator and Floor Operator

As an accelerator and floor operator, Haris’s work takes him all over the ALS. But, it is his photography hobby that has left an indelible mark on the ALS homepage. Let’s take a closer look at how he helps keep the ALS running and what brought him here in the first place. Read more »

Joint ALS/ALS-U Statement on Dark Time Delay

The ALS-U project recently made an extensive update to its project plan, resulting in a shift in the start of the one-year dark time from October 1, 2025, to June 22, 2026. The updated project schedule will allow the ALS to deliver more beamtime to users before the start of the dark time and further reduces the possibility that the ALS dark time will overlap with the APS’s ramp-up to full operations following their upgrade, currently in progress.

An Organic Transistor That Can Sense, Process, and Remember

Traditional AI hardware employs physically separated information sensing, processing, and memory architecture, a configuration that suffers from large energy and time overhead. Now, researchers have fabricated an organic transistor device that can simultaneously act as the sensor and processing core of a streamlined AI hardware system. Read more »

ALS Work on Roman Concrete Highlighted in German-French Documentary

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.

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 »

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.
