Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics
Advanced Materials, EarlyView.Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Morphology‐Controlled Silica Nanoparticle Coatings for Transparent Radiative Cooling
Advanced Materials Interfaces, EarlyView.Transparent radiative cooling coatings are achieved by immobilizing solid and hollow silica spheres on glass. Particle morphology within sub‐monolayer coatings is shown to govern the trade‐off between visible and atmospheric window reflectance. Hollow‐sphere structures enable reduced thermal emission losses while preserving transparency, highlighting ...

Non‐Continuous Iridescent Variable Structural Color Based on Metallic Surface Periodic Structures
Advanced Materials Interfaces, EarlyView.This study presents an ink‐free laser nanofabrication technique that generates periodic arched microstructures on titanium surfaces, achieving non‐continuous iridescent dual‐color switching. The ridge and side flanks of these structures possess distinct oxide film thicknesses, enabling angle‐dependent selective reflection of specific wavelengths.

Stretchable diffraction gratings for spectrometry
Optics Express, 2007 We have investigated the possibility of using transparent stretchable diffraction gratings for spectrometric applications. The gratings were fabricated by replication of a triangular-groove master into a transparent viscoelastic. The sample length, and hence the spatial period, can be reversibly changed by mechanical stretching.

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability
Advanced Materials Interfaces, EarlyView.Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.
