Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, Volume 37, Issue 46, November 20, 2025.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Optimization of Photolithographic Fabrication of Photonic Crystals and their Use in High Efficiency Solar Cells

Solar RRL, Volume 9, Issue 22, November 2025.
This study presents improved regular inverted pyramid structures, which should act as photonic crystals and thus are expected to highly increase light absorption. The prepared structures exhibit light trapping en par with random pyramid textured surfaces, but not as expected above.
