Ambient‐Pressure Superconductivity Onset at 10 K and Robust Tc under High Pressure in TiNbTaN3 Medium‐Entropy Nitride

open access: yesAdvanced Science, EarlyView.
The first observation of superconductivity in a bulk MEN TiNbTaN3 with Tc ≈ 10 K at ambient pressure and the electronic specific heat coefficient γ(H) exhibits nonlinear H‐dependence behavior, which is similar to other well‐studied multigap superconductors is reported.

Low‐Temperature Annealing Triggered Abnormal Strengthening in a Complex Concentration Alloy via Evolutive Short‐Range Ordering

open access: yesAdvanced Science, EarlyView.
Low‐temperature annealing enhances strength, ductility, and work hardening in CoNiV MEA. This originates from multi‐scale chemical short‐range orderings (SROs) formed during annealing, which promote dislocation slip planarity and reduce entanglement, enabling balanced mechanical properties through ordering strengthening.

Reconfigurable In–S Coordination in SPAN Cathodes: Unlocking High Sulfur Utilization and Fast Kinetics for Practical Li‒S Batteries

open access: yesAdvanced Science, EarlyView.
An amorphous indium–sulfur complex is embedded in SPAN matrix to create reversible In–S coordination bonds that dynamically break and reform during cycling. This bond reconfiguration actively anchors intermediate polysulfides and accelerates sulfur conversion kinetics, providing simultaneously high active material utilization and durable cycling ...

3D Topological Inorganic Electrides: Screening, Properties, and Applications

open access: yesAdvanced Science, EarlyView.
In inorganic electrides, zero‐, one‐, and two‐dimensional (0D, 1D, and 2D) interstitial anionic electrons interconnect within lattice cavities, collectively forming a three‐dimensional (3D) network, further coupling magnetism and topological features, leading to the emergence of 3D topological inorganic electrides.
