Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

Advanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

Advanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

Ultralow Loading Iridium Doped Hollandite Manganese Oxide Nanowires for Efficient Acidic Oxygen Evolution Reaction

Advanced Materials, EarlyView.
Ultralow iridium loading in hollandite MnO2 nanowires delivers an order of magnitude higher Ir mass activity than commercial IrOx for acidic water oxidation. Across pH and potential, Ir stays framework‐associated while Mn reconstructs, yet the most restructured catalyst is not the most dissolved, indicating that dissolution alone is an incomplete ...
