Sunscreen Composed of Nanofiber with Enhanced UV Protection and Thermal Comfort for Human Skin
Advanced Materials Technologies, EarlyView.A new type of sunscreen composed of nanofibers is presented that enhances UV scattering and reflection, in contrast to conventional sunscreens that rely on absorption agents to block UV radiation. This scattering‐based UV protection helps minimize thermal stress by reflecting UV energy.

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators
Advanced Materials Technologies, EarlyView.The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation
Advanced Optical Materials, EarlyView.Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Advanced Photonics Research, EarlyView.Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing
Advanced Robotics Research, EarlyView.This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
