Robust Spin Splitting and Fermiology in the Layered Altermagnet CoNb4${\rm CoNb}_4$Se8${\rm Se}_8$

open access: yesAdvanced Materials, EarlyView.
The emergence of an altermagnetic phase is demonstrated in the cobalt‐intercalated superconducting 2H‐NbSe2 polymorph. A combined theoretical and experimental approach directly probes the magnetism, the altermagnetic lifting of Kramers degeneracy, and the electronic phase space, establishing CoNb4Se8 as the first g‐wave altermagnetic layered material ...

Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

open access: yesAdvanced 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 ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.
