Adjustable Plasmonic Core–Shell Nanoparticles for Personalized Color Vision Correction

Advanced Engineering Materials, EarlyView.
This study introduces a personalized solution for correcting color vision deficiency (CVD) by embedding tunable core‐shell metal nanoparticles—a common nanotechnology—into contact lenses. By customizing the nanoparticles’ optical properties to filter specific wavelengths, these lenses address individual visual impairments, enhancing color ...

Multimaterial Approach to Improve the Mechanical Properties of a Novel Modified Auxetic Reentrant Honeycomb Structure

Advanced Engineering Materials, EarlyView.
A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films

Advanced Functional Materials, EarlyView.
Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

Advanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Roulette‐Inspired Physical Unclonable Functions: Stochastic yet Deterministic Multi‐Bit Patterning through the Solutal Marangoni Effect

Advanced Functional Materials, EarlyView.
Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...
