3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Meissner Effect and Nonreciprocal Charge Transport in Non‐Topological 1T‐CrTe2/FeTe Heterostructures

Advanced Materials, EarlyView.
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Field-Induced Magnetostructural Transitions in Antiferromagnetic Fe1+yTe1-xSx

, 2012
The transport and structural properties of Fe1+yTe1-xSx (x=0, 0.05, and 0.10) crystals were studied in pulsed magnetic fields up to 65 T. The application of high magnetic fields results in positive magnetoresistance effect with prominent hystereses in ...

Porous Bi2S3 Bulk With Excellent Thermoelectric Performance by Solid States Replacement and Low Melting‐Point Metal Volatilization

Advanced Materials, EarlyView.
By introducing FeCoNi medium‐entropy alloy, the bismuth sulfide (Bi2S3) material achieves a record‐high ZT of 1.1 at 773 K, owing to the solid‐states replacement reaction and the volatilization of low melting‐point metal. This strategy is also applicable to other sulfur‐based thermoelectric materials.

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to
