Lattice-Dependent Spin Textures in High-Tc Superconductors

Researchers found that in bismuth-based cuprate superconductors, charge imbalances caused by lattice distortions generate persistent and universal patterns of spin polarization. The results supply a previously missing but essential ingredient in efforts to understand the mechanisms driving the electronic behavior of high-temperature superconductors.

Excited States in CO2 Clusters Shed Light on Astrochemical Formation Mechanisms

A vacuum ultraviolet photoionization study conducted at the ALS revealed a new mechanism between molecules that converts high-energy ultraviolet light into free electrons. The results provide insights into interactions between CO2 and organic molecules, which are crucial for understanding astrochemical interactions as well as green chemistry and renewable energy development.

Nanoconfinement of High Hydrogen-to-Metal Ratio Lanthanum Hydrides in Functionalized Carbon Hosts

Metal hydrides with a high hydrogen content are important for materials-based hydrogen storage and high-temperature superconductivity. Nanoconfinement of metal hydrides in porous hosts is a promising strategy to tune the thermodynamic stability and control the hydrogen-to-metal ratio. X-ray absorption and photoelectron spectroscopy provided detailed information about the local chemical environment of LaHx species within carbon hosts. Read more »

Vote for New UEC Members: Term Starting in 2025

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 »
