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 »
Controlling the Structure and Morphology of Organic Nanofilaments Using External Stimuli
Coexisting organic helical and helicoidal crystalline nanofilaments formed by molecules with a bent molecular shape can now be transformed to a smectic liquid crystal phase or only helical nanofilaments by applying an electric field or irradiating the sample with UV light. 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.

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 »
