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 »
Insight into How Thermoresponsive Nanomaterials Work
By combining soft x-ray scattering with electron microscopy, researchers learned how nanoscale polymer assemblies in solution restructure in response to heating. The approach can be generalized to many complex, solution-phase, nanoscale processes, and holds promise for driving advances in applications from drug delivery to catalysis. Read more »
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.

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 »
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 »
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 »
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 »
