Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Magnesiated Si‐Rich SiOx Materials for High‐Performance Lithium‐Ion Batteries
Batteries &Supercaps, Volume 9, Issue 1, January 2026.Premagnesiated Si‐rich SiOx composite delivers high ICE and reversible capacity. Si/Mg2SiO4 composite is synthesized via high‐energy mechanical milling followed by MgH2 treatment. Cycle performance is improved without compromising ICE by forming a Mg2SiO4 phase that suppresses irreversible a‐SiO2 reactions and buffers volume changes in the Si‐rich ...
