Kinetically Controlling Surface Atom Arrangements in Thermally Robust, Amorphous High‐Entropy Alloy Nanoparticles by Solvent Selection

Advanced Science, EarlyView.
This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...

A Modern Roman‐Inspired Concrete with Daytime Radiative Cooling Capacity

Advanced Science, EarlyView.
Coolcrete, inspired by ancient Roman concrete, is a new cementitious material with photonic properties enabling passive daytime radiative cooling. Made from quicklime and zeolites, it reduces cooling energy demand, lowers CO2 emissions, and may eliminate urban heat islands.

Liquid Metal–Polyphenol Hybrids for Solar Steam Generation

Advanced Science, EarlyView.
The combination of liquid gallium nanoparticles, graphene, and a metal‐phenolic gel creates a unique architecture that can act as a highly efficient broad–spectrum solar light absorber. The resulting composite applied for solar steam generation can produce clean water with an evaporation rate of 3.4 kg m−2 h−1 under 1 Sun illumination from seawater ...

Reconstructing Focal Topological Curves through Vortex Spots from Multifocal Metasurfaces

Advanced Science, EarlyView.
Multichannel multifocal silicon metasurfaces are built to reconstruct focal topological curves using an array of vortex spots, and upconverted fluorescence is used to directly visualize the morphology of the near‐infrared focal fields. Abstract Structured light plays an important role in modern photonics.

Hot‐Pressing Annealing‐Induced Light Utilization Enhancement and Crystallinity Optimization Enable High‐Performance Narrowband Ultraviolet Photodetectors for Real‐Time Ultraviolet Radiation Monitors

Advanced Science, EarlyView.
By utilizing a hot‐pressing (HP) annealing strategy, Cs3Cu2I5 films with larger grains vertically spanning the entire thickness are fabricated. Because HP annealing enhances light utilization and charge transport in Cs3Cu2I5/GaN heterojunction, the HP device achieves superior detection performance while maintaining narrowband photoresponse to UVA/UVB ...
