Thermo-adaptive interfacial solar evaporation enhanced by dynamic water gating

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 22, 2024

Abstract Solar-driven evaporation offers a sustainable solution for water purification, but efficiency losses due to heat dissipation and fouling limit its scalability. Herein, we present bilayer-structured solar evaporator ( SDWE ) with dynamic fluidic flow mechanism, designed ensure thin supply self-cleaning capability. The porous polydopamine PDA layer on nickel skeleton provides photothermal functionality microchannels, while the thermo-responsive sporopollenin bottom acts as switchable gate. Using confocal laser microscopy micro-CT, demonstrate that this unique structure ensures steady of layers, enhancing by minimizing latent at high temperatures. Additionally, system initiates process through bulk convection when temperature drops salt accumulation, thus maintaining increased efficiency. Therefore, optimized p-SDWE sample achieved rate 3.58 kg m −2 h −1 using 93.9% energy from 1 sun irradiation, produces 18–22 liters purified per square meter day brine water. This transport mechanism surpasses traditional day-night cycles, offering inherent thermal adaptability continuous, high-efficiency evaporation.

Expanding Transparent Covalently Attached Liquid‐Like Surfaces for Icephobic Coatings with Broad Substrate Compatibility

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

Published: Jan. 2, 2025

Abstract Ice accretion causes significant energy losses and safety risks across various sectors. Recent research shows that liquid‐like surfaces (LLS) with ice‐shedding properties can be created by covalently attaching linear polymer chains onto smooth substrates sufficient hydroxyl group densities. To expand the substrate scope for LLS, a novel system using non‐halogenated organosilanes attached to commercial epoxy‐silicon ( EpSi ) coating is proposed. The layer, easily applied simple methods, serves as intermediate layer R = 0.94 nm q 0.76 nm). Air plasma activation increases density on , enabling LLS formation via immersion in an organosilane solution. resulting exhibits low contact angle hysteresis (<10°), sliding (SA < 14°), ice adhesion strength τ 20 kPa).

Droplet slipperiness despite surface heterogeneity at molecular scale

Nature Chemistry, Journal Year: 2023, Volume and Issue: 16(4), P. 506 - 513

Published: Oct. 23, 2023

Abstract Friction determines whether liquid droplets slide off a solid surface or stick to it. Surface heterogeneity is generally acknowledged as the major cause of increased contact angle hysteresis and line friction droplets. Here we challenge this long-standing premise for chemical at molecular length scale. By tuning coverage self-assembled monolayers (SAMs), water angles change gradually from about 10° 110° yet are low low-coverage hydrophilic SAMs well high-coverage hydrophobic SAMs. Their slipperiness not expected based on substantial featuring uncoated areas substrate beyond size molecule probed by metal reactants. According dynamics simulations, both low- originates mobility interfacial molecules. These findings reveal unknown counterintuitive mechanism slipperiness, opening new avenues enhancing
