Designing interfacially stable Na-ion polymer electrolytes with tailored local solvation structures.

Azodicarbonamide (ADA) is selected as an additive to the polymer electrolyte (PE) to improve the stability of the NaFeMnNiO cathode. ADA can capture hydrogen from the polymer and induce local structures, enhancing the ionic conductivity of the PE. Moreover, the dehydrogenated ADA can bond to Fe ions, preventing the PE from decomposing.

Noble-Metal High-Entropy-Alloy Nanoparticles: Atomic-Level Insight into the Electronic Structure.

The compositional space of high-entropy-alloy nanoparticles (HEA NPs) significantly expands the diversity of the materials library. Every atom in HEA NPs has a different elemental coordination environment, which requires knowledge of the local electronic structure at an atomic level. However, such structure has not been disclosed experimentally or theoretically.
