HCl‐Free Mechanochemical Synthesis of Lithium Niobium Oxychlorides

open access: yesChemistry–Methods, Volume 6, Issue 8, August 2026.
A novel mechanochemical route utilizing lithium niobate precursors and chlorides eliminates corrosive HCl byproduct, enabling the direct synthesis of LiNbOCl4 with a high ionic conductivity of 11.8 mS cm−1. Halide‐based oxychloride electrolytes, including LiNbOCl4, are promising candidates for all‐solid‐state batteries (ASSBs) due to their high ionic ...

Inverse‐Designed Silicon Nitride Bimodal Mode Converter for Interferometric Sensors

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Inverse‐designed bimodal mode converters are demonstrated on two silicon nitride platforms. The devices convert the fundamental mode into near‐balanced pairs of the fundamental and higher‐order modes up to the third order. They are compact and fabrication‐tolerant. Characterization of a bimodal interferometer incorporating these converters demonstrates
