Enhanced Mechanical and Shape Memory Properties of Laser Direct Energy Deposited CoCrFeMn High Entropy Alloy by Carbon Addition

Advanced Engineering Materials, EarlyView.
Feasibility of improving the mechanical and shape‐memory properties of a CoCrFeMn high‐entropy alloy through carbon addition is investigated. The recovery strain of the carbon‐containing alloy is approximately four to five times higher than that of the carbon‐free alloy.

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Pure electromagnetic-gravitational interaction in Hořava–Lifshitz theory at the kinetic conformal point

European Physical Journal C: Particles and Fields, 2020
We introduce the electromagnetic-gravitational coupling in the Hořava–Lifshitz framework, in $$3+1$$ 3+1 dimensions, by considering the Hořava–Lifshitz gravity theory in $$4+1$$ 4+1 dimensions at the kinetic conformal point and then performing a Kaluza ...

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

Advanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.
