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 »
Insight into How Thermoresponive 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 »

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 »
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 »
