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.

August 2023 Message from the UEC

UEC Chair Inna Vishik shares why this year’s User Meeting will be so special as well as some tips for making the most of the meeting. She also reminds users of town halls and other ways to understand and get involved with shaping the post-upgrade ALS. Read more »

Fluctuations Mark Phase Changes in Magnetic Films

Researchers discovered that nanoscale spin fluctuations deep inside ordered states of a magnetic film can characterize phase transitions, independent of underlying magnetic interactions. The results provide a new way to predict and understand phase transitions in materials relevant to high-density, energy-efficient microelectronics. Read more »PPT-icon-35 PDF-icon-35

Eco-Friendly Processing of Organic Photovoltaics

Researchers controlled the mixing of electron-donating and -accepting constituents of an organic photovoltaic (OPV) material made using a process that replaces toxic solvents with water. With efficiencies comparable to less eco-friendly OPVs, this material shows promise for many advanced device and building applications. Read more »PPT-icon-35 PDF-icon-35

How Scientists Are Accelerating Next-Gen Microelectronics

A new center, called CHiPPS—or the Center for High Precision Patterning Science—led by Berkeley Lab microelectronics expert Ricardo Ruiz, could accelerate the next revolution in microchips, the tiny silicon components used in everything from smartphones to smart speakers, life-saving medical devices, and electric cars.

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 »

Organic Matrix Derived from Host–Microbe Interplay Contributes to Pathological Renal Biomineralization

A composite image of a rare form of kidney stone, illustrating extensive organic filamentous networks abundant with immune response-related proteins such as calprotectin (displayed in red), myeloperoxidase (in yellow), and DNA molecules (in blue). Originating from intricate host-microbe interplay, these organic networks promote the heterogeneous nucleation and precipitation of inorganic particulates. 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.

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.
