Abstract We have synthesized a quinone‐incorporated bistriarylamine donor‐acceptor‐donor (D–A–D) semiconductor 1 by B(C 6 F 5 ) 3 (BCF) catalyzed C−H/C−H cross coupling via radical ion pair intermediates. Coordination of Lewis acids BCF and Al(OR (R =C(CF to the afforded diradical zwitterions 2 integer electron transfer. Upon binding acids, LUMO energy is significantly lowered band gap narrowed from 1.93 eV ( 1.01 1.06 ). are rare near‐infrared (NIR) dyes with broad absorption both centered around 1500 nm. By introducing photo generator, can be generated light‐dependent control. Furthermore, transfer process also reversibly regulated addition CH CN. In addition, temperature sharply increased reached as high 110 °C in 10 s upon irradiation near‐infrared‐II (NIR‐II) laser (1064 nm, 0.7 W cm −2 ), exhibiting fast response laser. It displays excellent photothermal stability (PT) conversion efficiency 62.26 % high‐quality PT imaging.

Manipulating 2D Membrane Interlayer Channels with Accelerated Mass‐Transfer Behavior to Boost Solar Desalination

Small, Год журнала: 2024, Номер unknown

Опубликована: Май 10, 2024

Abstract The scarcity of fresh water necessitates sustainable and efficient desalination strategies. Solar‐driven steam generation (SSG), which employs solar energy for evaporation, has emerged as a promising approach. Graphene oxide (GO)‐based membranes possess advantages like capillary action Marangoni effect, but their stacking defects dead zones flexible flakes hinders transportation, thus the evaporation rate lag behind unobstructed‐porous 3D evaporators. Therefore, fundamental mass‐transfer approach optimizing SSG evaporators offers new horizons. Herein, universal multi‐force‐fields‐based method is presented to regularize membrane channels, can mechanically eliminate inherent interlayer stackings defects. Both characterization simulation demonstrate effectiveness this across different scales explain intrinsic mechanism enhancement. When combined with structurally optimized substrate, 4Laponite@GO‐1 achieves 2.782 kg m −2 h −1 94.48% efficiency, comparable most Moreover, exhibits excellent cycling stability (10 days) tolerance extreme conditions (pH 1–14, salinity 1%–15%), verifies robust structural regularized channels. This optimization strategy provides simple way enhance performance GO‐based membranes, facilitating extensive application in purification technologies.

Hierarchically Promoted Light Harvesting and Management in Photothermal Solar Steam Generation

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 15, 2024

Abstract Solar steam generation (SSG) presents a promising approach to addressing the global water crisis. Central SSG is solar photothermal conversion that requires efficient light harvesting and management. Hierarchical structures with multi‐scale management are therefore crucial for SSG. At molecular sub‐nanoscale levels, materials fine‐tuned broadband absorption. Advancing nano‐ microscale, tailored enhance through internal reflections, scattering, diverse confinement effects. macroscopic level, capture optimized rationally designed device geometries, configurations, arrangements of absorber materials. While performance relies on various factors including heat transport, physicochemical interactions at water/air material/water interfaces, salt dynamics, etc., utilization holds predominant role because sunlight sole energy source. This review focuses critical, yet often underestimated, hierarchical harvesting/management different dimensional scales in By correlating structure‐property relationships, recent advances discussed, shedding current challenges possible future trends opportunities this domain.
