Advanced Materials Technologies, EarlyView.Flexible piezopolymer ultrasound transducers are engineered by tailoring the electrode–piezopolymer interface using metallic, flake‐based, and porous graphene electrodes. Laser‐induced graphene's porous structure enables polymer infiltration, strengthening interfacial coupling and enhancing piezoelectric response and acoustic output.

Cross‐Phase Modulation via Time‐Varying Epsilon‐Near‐Zero Metasurfaces
Advanced Optical Materials, EarlyView.Time‐varying epsilon‐near‐zero metasurfaces are shown to enable cross‐phase modulation beyond conventional ENZ excitation. By engineering dual absorption bands and exploiting oblique ultrafast pumping, large and broadband frequency translations are achieved at low pump energies.

Advanced Optical Materials, EarlyView.Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.

Controlling Ultrafast Photonic‐Plasmonic Coupling in a Hybrid Platform for Biosensing Applications
Advanced Optical Materials, EarlyView.A metal–dielectric hybrid composed of gold nanocaps on opal exhibits a broad near‐infrared plasmonic resonance interacting with the photonic bandgap under ultrafast transient conditions. This coupling can be controlled by varying the excitation wavelength and is responsive to bacterial deposition, opening new opportunities for ultrafast biosensing ...

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces
Advanced Optical Materials, EarlyView.Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze
