Local Chemical Enhancement and Gating of Organic Coordinated Ionic-Electronic Transport
Record ion mobility and conductivities are revealed within a nanoscopic interfacial superhighway of an organic mixed ionic-electronic conductor. Fast ion transport can be controlled by hydrophobicity of molecules local to this channel, effectively gating ion access to the superhighway. This mechanism is used in a novel chemical sensing device which detects the dynamics of a local, buried chemical reaction. Read more »
Advancing high-temperature electrostatic energy storage via linker engineering of metal–organic frameworks in polymer nanocomposites
High-performance, thermally resilient polymer dielectrics are essential for film capacitors used in advanced electronic devices and renewable energy systems, particularly at elevated temperatures where conventional polymers fail to perform. Herein, we unravel the untapped potential of UiO-66 metal–organic framework (MOF) derivatives as exceptional nanofillers for tuning the properties of the widely used polyetherimide (PEI). Read more »
Jamming Giant Molecules at Interface in Organic Photovoltaics to Improve Performance and Stability
Giant molecule acceptors (GMAs), known for their large size and intricate functional structures, are an emerging focus in materials science. Through implementation of an interface-enhanced layer-by-layer fabrication strategy, we have successfully demonstrated that GMA with designed electronic structure at interfaces can effectively improve OPV device performance.

In Memoriam: Terry McAfee, Senior Scientific Engineering Associate
The ALS community is saddened to lose Terry McAfee, who was a caring and hardworking presence since he started coming to the facility as a graduate student. From ALS user to full-time staff, he always strove to create a welcoming environment. We will remember his passion for STEM and his love for his family. Read more »
Magnetization Switching in Highly Magnetostrictive Microstructures
Researchers learned how the size, shape, and orientation of microstructures affect how they switch magnetization directions in response to an applied voltage. The work advances our understanding of strain-responsive composite materials for use in energy-efficient electronic applications such as memory devices, sensors, and actuators. Read more »
Summer 2024 Shutdown Recap
The ALS is back in user operation after more than two months of shutdown. By now, more than 80% of the Accumulator Ring (AR) has been installed, as well as both of its radio frequency (RF) cavities. A number of other tasks were also completed. Read more »
Tracking Oxidation in “High-Entropy” Alloys with Multiple Principal Elements
For extreme applications such as nuclear fusion reactors and high-temperature jet engines, scientists are experimenting with “high-entropy” alloys that consist of many metals mixed together in equal proportions. In this work, researchers begin to unravel how these materials degrade under high-temperature oxidative environments. Read more »
Studying Interfacial Effects in Solid-Electrolyte Batteries
An ambient-pressure probe of a solid electrolyte revealed how surface electrochemical mechanisms lead to poor electrolyte performance and battery failure. The results can help scientists engineer better coatings and interfaces, which are essential for building safer and better-performing batteries, particularly for use in vehicles. Read more »
