Ultra‐High‐Capacity of Earth‐Abundant Cathodes Enabled by Excess Fluoride‐Ion Insertion/Extraction

Advanced Energy Materials, EarlyView.
A perovskite oxyfluoride SrFeO2Fx can accomodate excess F– beyond x = 1 in the structure with oxygen redox (O–O bond formation). The Sr‐substituted CaFeO2Fx (Ca0.8Sr0.2FeO2Fx) provides an extremely large capacity of 580 mAh g−1 (2595 mAh cm−3). This research will provide new design principles for the development of all‐solid‐state fluoride‐ion battery ...

Selective Electrochemical Reduction of CO2 to Metal Oxalates in Nonaqueous Solutions Using Trace Metal Pb on Carbon Supports Enhanced by a Tailored Microenvironment

Advanced Energy Materials, EarlyView.
Encapsulating trace lead (Pb) in carbon electrodes with a fluoropolymer tailors the microenvironment for carbon dioxide (CO2) reduction. This enhances efficiency and selectivity, offering a tunable approach to guide reaction pathways and improve product outcomes in electrochemical CO2 conversion.

Toward Rapid Analysis of Unsaturated Fatty Acid Oxidation in Edible Oils via Square‐Wave Voltammetry

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Square‐wave voltammetry (SWV) was investigated as a potential analytical tool for quantitation of unsaturated fatty acid oxidation in edible oils exposed to high heat. A traditional linear regression calibration curve and a novel single‐point calibration method were used to quantitate linoleic acid in oxidized oil samples.
