Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

Advanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

British Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

Bridging Horizontal to Vertical Radiative Cooling

Advanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Dynamic Performance Analysis for an Absorption Chiller under Different Working Conditions

Applied Sciences, 2017
Due to the merits of energy saving and environmental protection, the absorption chiller (AC) has attracted a lot of attention, and previous studies only concentrated on the dynamic response of the AC under a single working condition. However, the working

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability

Advanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Circadian‐Inspired Hydrogel Moisture Electricity Generation

Advanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...

Synergistic Effects in Multistate Black Electro‐Thermochromic Smart Windows for Energy‐Efficient Modulation of Solar Heating

Advanced Science, EarlyView.
Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...
