Self‐Regulating Sodium‐Ion Battery Materials: From Phase Reconstruction to Functional Activation
Advanced Materials, Volume 38, Issue 19, 1 April 2026.Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...

Advanced Science, Volume 13, Issue 19, 2 April 2026.A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.

A finger mechanism for adaptive end effectors [PDF]
, 2002 This paper presents design and analysis of a rigid link finger, which may be suitable for a number of adaptive end effectors. The design has evolved from an industrial need for a tele-operated system to be used in nuclear environments.

Ecology and Evolution, Volume 16, Issue 4, April 2026.The two color morphs of the Iberian–Atlantic Paramuricea complex show little genetic divergence, and their species boundaries have remained unclear. By analyzing gametogenesis, spawning timing, fertilization environment, and early life‐history traits, we reveal strong prezygotic barriers and divergent developmental and dispersal strategies between the ...
