Transparent Photothermal Slippery Surface Based on Monolayer Self‐Assembled MXene Film for Anti‐Fogging and De‐Icing

Advanced Science, EarlyView.
The ultrathin (2.5 nm) MXene film self‐assembled at liquid interfaces breaks the trade‐off between transparency (82.5 %) and photothermal conversion effect (DT∼25.1°C ± 2.9 °C) under 100 mW cm−2. After encapsulated by a slippery surface with low adhesion, this transparent film can be applied in smart windows, eyewear, and optical sensors to autonomous ...

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

Advanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

Underwater Acoustic Camouflage by Wettability Transition on Laser Textured Superhydrophobic Metasurfaces

Advanced Materials Interfaces
The superhydrophobicity of submerged surfaces typically pertains to the trapped air film at the liquid–solid interface, subject to wettability transitions from a Cassie–Baxter state to more unstable states that gradually collapse to high retention ...

Non‐Destructive Hydrophobic Engineering of Inverse Catalysts for Methanol Synthesis from CO2

Advanced Science, EarlyView.
In this study, we report a non‐destructive hydrophobic modification strategy for ZrO2/Cu catalyst through physical mixing with PDVB. The optimized ZrO2/Cu‐PDVB catalyst achieves a methanol space‐time yield of 920.10 mgCH3OH gcat−1 h−1 under mild conditions, outperforming the unmodified catalyst by 30 %.

Heterogeneous Wettability‐Based Construction of Two‐Phase Interfaces for Underwater Reversible Adhesion

Advanced Science, EarlyView.
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...

Scalable Laser Processing Enables Transparent, Accretion Scale‐Independent, Ice‐Shedding Glass

Advanced Science, EarlyView.
We demonstrate a scalable laser‐based method to create wave‐like micro‐patterns on glass surfaces that counter the conventional view that roughness increases ice adhesion. These patterns direct crack propagation at the ice–glass interface, enabling low‐force, multi‐directional ice detachment while maintaining substrate transparency. A theoretical model

Tailoring surface interactions, contact angles, drop topologies and self-assembly using laser irradiation

, 2012
UV laser irradiation (lambda = 193 nm), below and above damage thresholds, is used to both alter and pattern the surface properties of borosilicate slides to tune and control the contact angle of a water drop over the surface.
