Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Dynamic Magnonic Crystals Based on Spatiotemporal Plasmon Excitation

open access: yesAdvanced Materials, EarlyView.
Hybrid magnonic‐plasmonic metamaterials enabling spatiotemporal optical control of spin‐wave transport are demonstrated. These structures integrate periodic stripes of gold nanodisk arrays with low‐damping yttrium iron garnet films to realize dynamically reconfigurable magnonic crystals.

Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

open access: yesAdvanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

open access: yesAdvanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Granular Hydrogels as Brittle Yield Stress Fluids

open access: yesAdvanced Materials, EarlyView.
This work reports the Kamani‐Donley‐Rogers yield stress fluid model can describe granular hydrogel deformation. The model robustly captures transient rheology and self‐healing behavior for granular gels of varying composition using only six parameters. This framework provides new insight regarding the effect of material parameters on granular yielding ...

Skeletal High‐Strength Nanoporous Copper and Metamaterials: The Hakka Tulou Design Heritage

open access: yesAdvanced Materials, EarlyView.
Inspired by the Hakka Tulou walls, skeletal nanoporous copper is fabricated via a two‐phase MnCu precursor and controlled dealloying. This strategy achieves high strength (200 MPa) and large specific surface area (27.6 m2/g), and extends to lattice metamaterials with hierarchical porosity, offering new design pathways for multifunctional metal ...
