Solvation‐Mediated Shift From Solvent‐ to Anion‐Derived Solid Electrolyte Interphases for Stable Calcium Metal Anodes

Advanced Science, EarlyView.
An ion‐dipole interaction based strategy is proposed to capture thermodynamically unstable solvents and restructure the coordination environment of calcium ions by introducing ionic liquid co‐solvents, thus suppressing excessive solvent decomposition. Therefore, a smooth and dense solid‐electrolyte interphase dominated by inorganic components is formed

Unraveling the Synergistic Activity‐Stability Enhancement of a High‐Entropy Perovskite Air Electrode for Dual Ceramic Electrochemical Cells

Advanced Science, EarlyView.
A high‐entropy air electrode material, Gd0.2Pr0.2Ba0.2Sr0.2Ca0.2FeO3−δ (GPBSCF), is developed for both solid oxide fuel cells and reversible protonic ceramic cells. Its enhanced activity stems from increased oxygen vacancies/holes. The stability improvement is attributed to lattice distortion, while thermal expansion reduction is synergistically due to

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

GPU Computing in XAFS

Journal of Physics: Conference Series, 2013
Modern graphics processing units (GPUs) are powerful parallel computers. Porting the mathematically intense, parallelizable algorithms of XAFS to run on GPUs should expand the scale of tractable XAFS calculations. Part of a time-limiting subroutine in FEFF 8.4 (fms) was converted to run on a GPU, showing significant performance gains.

Efficient Electrocatalytic Conversion of CO2 to Pure Formic Acid Solutions via Strain‐Engineered Bismuth Nanosheets

Advanced Science, EarlyView.
Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...
