Revealing the Giant Electromechanical Effects in Yttria‐Stabilized Zirconia Single Crystal

Advanced Science, EarlyView.
Giant electromechanical responses are uncovered in yttria‐stabilized zirconia single crystal (SC‐YSZ), exhibiting pronounced orientation dependence. The giant electrostriction and piezoelectricity are directly correlated with the long‐range transport kinetics of oxygen vacancies.

Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

Advanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Defect-Engineered LiYO₂ Interlayers Enabling Fast Interfacial Li⁺ Transport in All-Solid-State Batteries. [PDF]

Adv Sci (Weinh)
Defect‐engineered LiYO2 interlayers are designed through aliovalent Zn2+ and Zr4+ substitution to regulate Li+ point‐defect chemistry in Ni‐rich cathodes. Compared with Li‐excess‐type LYZnO, Li‐vacancy‐type LYZrO enables faster Li+ transport, suppresses Li6PS5Cl decomposition, lowers interfacial resistance, and mitigates polarization growth, thereby ...

Interfacial Engineering of Iodine‐Polymer‐Carbon Hybrid Cathodes for High‐Energy Zn//I2 Microbatteries

Advanced Science, EarlyView.
A cathode‐confined iodine strategy employing a synergistic polyaniline/activated‐carbon hybrid enables highly reversible halogen redox chemistry in coplanar Zn//I2 microbatteries. Enhanced iodine utilization, suppressed iodine dissolution, and accelerated charge‐transfer kinetics deliver durable, safe, and integrable microscale energy‐storage devices ...

Breaking the Kinetics–Loading Trade‐Off in Zinc‐Ion Hybrid Capacitors Through Synergistic Electron–Ion Transport Design

Advanced Science, EarlyView.
High‐mass‐loading carbon cathodes are essential for practical zinc‐ion hybrid capacitors but suffer from severe transport limitations. By combining low‐tortuosity freeze‐dried pore channels with carbon nanotube conductive networks, simultaneous optimization of ion and electron transport is achieved, enabling high‐rate, long‐life pouch cells and ...

Long‐Chain Molecule Reconstruction of Novel Solvation Structure to Stabilize Zinc Metal Anode

Advanced Science, EarlyView.
Triethylene glycol diacetate (TGD), with unique long‐chain characteristics and rich oxygen‐containing functional groups, was used as an electrolyte additive to reconstruct the solvation structure. TGD can reduce the erosion of H2O molecules on the Zn anode, effectively homogenize the electric field distribution. Therefore, the Zn//Zn symmetric cell can

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

Advanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...
