Recent advances in thermally localized solar evaporation hold significant promise for vapor generation, seawater desalination, wastewater treatment, and medical sterilization. However, salt accumulation is one of the key bottlenecks reliable adoption. Here, we demonstrate highly efficient (>80% solar-to-vapor conversion efficiency) rejecting (20 weight % salinity) by engineering fluidic flow a wick-free confined water layer. With mechanistic modeling experimental characterization transport, show that natural convection can be triggered water. More notably, there exists regime enabling simultaneous thermal localization rejection, i.e., significantly accelerates rejection while inducing negligible additional heat loss. Furthermore, broad applicability integrating this layer with recently developed contactless evaporator report an improved efficiency. This work elucidates fundamentals transport offers low-cost strategy high-performance evaporation.

Using minimal photothermal material to achieve maximum evaporation rate is extremely important for practical applications of interfacial solar technology. In this work, we found that with the increase in size surfaces, decreased. Both experimental and numerical simulation results confirmed when surface increased, middle portion acted as a "dead zone" little contribution water evaporation. Based on this, was selectively removed, counterintuitively, both vapor output were increased due re-configured enhanced convection above entire surface. As such, work developed an strategy higher vapour while using less material.

Abstract Plastic waste caused by the extensive usage of face masks during COVID‐19 pandemic has become a severe threat to natural environment and ecosystem. Herein, an eco‐friendly approach repurpose mask for clean water production via solar thermal evaporation is proposed. By taking advantage its interwind structure, holds promise be ideal candidate material constructing photothermal evaporator. In‐situ surface modifications are performed successively with polyvinyl alcohol polypyrrole improve wettability absorption (97%). The obtained mask‐based evaporator achieves significantly enhanced efficiency (91.5%) long‐term salt‐rejection stability. harvested befits plant growing enable farming on sea surface. A floating prototype then developed demonstrate autonomous ocean farming, plants successfully cultivated over time. As such, proposed strategy provides promising solution towards ecological sustainability tapping multiple benefits. image

The interactions between moisture and materials give rise to the possibility of moisture-driven energy generation (MEG). Current MEG devices only establish this interaction during water sorption in specific configurations, conversion is eventually ceased by saturated uptake. This paper reports an asymmetric hygroscopic structure (AHS) that simultaneously achieves harvesting storage from absorption. AHS constructed deposition a ionic hydrogel over layer functionalized carbon. Water absorbed air creates wet-dry asymmetry across hence in-plane electric field. can be perpetually maintained even after triggers spontaneous development electrical double (EDL) carbon surface, which termed hygro-ionic process, accounting for capacitive properties AHS. A peak power density 70 µW cm-3 was realized geometry optimization. shows ability recharged either itself owing self-regeneration effect or via external means, allows it serve as device. In addition insights into moisture-material interaction, AHSs further potential electronics powering assembled devices.
