Published: Jan. 2, 2025

Abstract Interfacial solar evaporation offers a green and sustainable solution to solve clean water shortages via solar‐driven desalination. However, salt crystallization accumulation on evaporators have become the primary hindrances long‐term practical application of interfacial technology. To tackle this challenge, photothermal evaporator with novel parallel two‐water paths strategy is developed in study. Unlike conventional one‐way path, which generally leads at supply end surfaces, thereby limiting lifespan compromising performance, here, second ion diffusion distribution within reconfigured optimized. No occurs either surfaces or paths, eliminating impact performance enabling convenient collection. A high stable rate 3.09–3.26 kg m −2 h −1 recorded over 84 continuous NaCl (3.5 wt.%) without evaporator, making it an ideal for zero liquid discharge evaporation.

Mesoporous Nanogel Sprays as Universal Evaporation Interface Modifiers for Boosting Water‐Cluster Evaporation

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 11, 2025

Abstract Accelerating water evaporation is vital for processes like photosynthesis, dehydration, and desalination. Optimizing the pore structure interfacial properties of evaporative materials can reduce enthalpy increase efficiency. However, integrating interface with transport channels poses significant design challenges complicates low‐enthalpy analysis. To address these challenges, a hydrophilic nanovesicle gel developed hydrophobic mesoporous as an ideal spray. This spray effectively upgrades their universal substrates (including PVA hydrogels, balsa wood, nanofiltration membrane, cellulose paper, nylon fabrics, etc.), enabling simple preparation materials. The sprayed samples, at low spraying dose 40 mg cm −2 , achieved rates 1.58 3.26 kg m h −1 under 0.5 1 sun irradiance, which are 297% 268% higher than respective substrates. These nanogels offer benefits edibility, cost, ease use, compatibility various substrates, showing great potential in seawater desalination, dehydration technology, crop yield enhancement, coating/paint drying. More importantly, this work highlights need researchers to focus on surface materials, rather merely using bulk gels, development high‐performance

Abstract Sunlight/electricity‐driven thermal evaporation has been demonstrated as a promising strategy to obtain distilled water from seawater, but their practical applications are still limited by unsatisfactory photoabsorption and serious water‐electrolysis during photothermal/electrothermal evaporation. Inspired Paradisaeidae's feather electric kettle, the biomimetic design of fabrics for realizing all‐weather is reported.
