Physical origins of current and temperature controlled negative differential resistances in NbO₂

The development of future computation devices will be aided by a better understanding of the physics underlying material behaviors. Using thermoreflectance and spatially resolved X-ray microscopy, Kumar et al. elucidate the origin of two types of negative differential resistance in NbO₂ memristors.

Coupling between oxygen redox and cation migration explains unusual electrochemistry in lithium-rich layered oxides

Lithium ion battery electrodes employing anion redox exhibit high energy densities but suffer from poor cyclability. Here the authors reveal that the voltage of anion redox is strongly affected by structural changes that occur during battery cycling, explaining its unique electrochemical properties.

Chemical composition mapping with nanometre resolution by soft X-ray microscopy

A soft X-ray ptychography approach can now image 5-nm-sized objects. Chemical component distributions in the delithiation of LiFePO₄ nanoplates — a process relevant for energy storage — links structural defects to chemical phase propagation.

Variations of organic functional chemistry in carbonaceous matter from the asteroid 162173 Ryugu

A new study of samples from the Ryugu asteroid reveal a greater diversity of macromolecular organic matter than that found in related carbonaceous meteorites. Researchers find distinct populations of alkyl-aromatic grains, and organic carbonate is found with coarse-grained clay minerals

Three-dimensional localization of nanoscale battery reactions using soft X-ray tomography

Here the authors show the development of soft X-ray ptychographic tomography to quantify the electrochemical state and resolve phase boundaries throughout the volume of individual nano-particles from a composite battery electrode.

Current-induced transition from particle-by-particle to concurrent intercalation in phase-separating battery electrodes

Investigation of the individual state-of-charge of particles in the phase-separating battery electrode lithium iron phosphate reveals that the fraction of active particles is highly dependent on cycle rate and direction. The findings could lead to enhanced current uniformity and cycle life in other electrode systems.
