6.1% Volumetric Negative Thermal Expansion Induced by the Reversible Reconstructive Phase Transition in Pb‐Free Bi1−xLnxCoO3 (Ln: Lanthanoid)

Advanced Science, EarlyView.
Perovskite‐type oxide lanthanoid‐substituted BiCoO3 exhibits a reversible negative thermal expansion (NTE) originated from the coordination change from the CoO5 pyramid to the CoO6 octahedron due to melting of the dxy orbital ordering in the d6 electron configuration, and the 6.1% volume shrinkage in Bi0.82Nd0.18CoO3 is the largest ever observed in the

Thermal Stability of Ultrafine Grained Pure Copper Prepared by Large Strain Extrusion Machining

Metals, 2018
Ultrafine grained (UFG) pure copper chips with improved material strength have been successfully prepared by large strain extrusion machining (LSEM). However, the thermal stability of the UFG chips has been a key characteristic that has restricted their ...

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

Advanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength‐Ductility Synergy

Advanced Science, EarlyView.
Electroshock treatment triggers atomic rearrangement, transforming disordered grain boundaries into ordered states without inducing recrystallization. This grain boundary ordering effectively relieves strain concentration and strengthens boundaries, enabling a simultaneous improvement in both strength and ductility.

Orientation‐Engineered Insulator‐Metal Transition in Vanadium Dioxide

Advanced Science, EarlyView.
Crystallographic orientation engineering in VO2/TiO2 heterostructures enables tunable insulator‐metal transitions. The high‐Miller‐index (102) orientation breaks in‐plane mirror symmetry, inducing anisotropic transport, while its inclined oxygen channels accelerate protonation kinetics.

Preparation of Polycrystalline CdTe Films by Annealing of Amorphous Films Electrodeposited from Ammoniacal Alkaline Baths

High Temperature Materials and Processes, 2012
A new route to prepare polycrystalline CdTe films using electrodeposition of amorphous Cd-Te films and subsequent annealing was investigated. Amorphous Cd-Te films with Te-rich compositions could be electrodeposited from ammoniacal alkaline aqueous ...
