Nature of Surface Microcracks on Phosphorus Micro-Alloyed Copper

The effect of plastic deformation and environment on the appearance of surface microcracks on phosphorus micro-alloyed copper (Cu-OFP) was studied by tensile test, scanning electron microscopy and focused ion beam milling (SEM-FIB).

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

Advanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Controlling Epitaxial Zn Growth via Guided Laser Patterning toward High‐Performance 6Ah Aqueous Zn||I2 Batteries

Advanced Science, EarlyView.
A scalable laser‐assisted surface patterning method regulates zinc ion flux and promotes lateral epitaxial growth for stable aqueous batteries. Periodic micro‐holes effectively minimize interfacial resistance and reconstruct the zinc texture to favor the compact (002) basal plane. This structured anode suppresses both dendrite propagation and parasitic

Dramatic Enhancement and Integration of Properties in Pork Belly‐Inspired All‐Biomass Composite Films via Facile, Sustainable, and Controllable Design

Advanced Science, EarlyView.
A pork belly‐inspired all‐biomass composite film was constructed through layer‐by‐layer assembly of cellulose nanofibers (CNFs), gelatin, and graphitized carbon nanosheets (GCNs) via hydrogen bonding and π–π stacking interactions. The excellent mechanical properties, effective thermal management, and outstanding EMI shielding performance of the ...

Zr Incorporation Into Lithium Nickel Oxides: Bulk or Surface Substitution?

Advanced Science, EarlyView.
Mechanism of Zr incorporation into lithium nickel oxide (LNO) cathodes is studied from atomistic to macroscale. Zr doping enhances cyclability of Li‐ion batteries with LNO via bulk, interface, and grain boundary optimization leading to structural integrity at atomistic‐ and micro‐scale of secondary particle aggregates.

Post‐Synthetic Cerium Modification of Commercial NCM811 for Concurrent Cycling and Safety Upgrading

Advanced Science, EarlyView.
Cerium ion doping and CeO2 coating work synergistically to reinforce commercial NCM811 cathodes. This strategy stabilizes the lattice and strengthens the interface against degradation and side reactions. The modified cathode shows enhanced rate capability and cycling stability.
