Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.

A Wireless, Passive Multimodal Wearable Sensor With Decoupled Sensing Capabilities
A wireless passive multimodal electronic skin is presented for the simultaneous perception of pressure, humidity, and odor through a frequency‐divided LC resonator array. The decoupled sensing architecture suppresses cross‐interference and enables independent signal readout under superimposed stimuli while maintaining high stability.

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...
