Experimental Investigation of R134a and Its Alternative Refrigerant R513A Flow Boiling in Microchannel Tube

Zhileng xuebao
This study investigates the flow boiling characteristics of R134a and its alternative refrigerant R513A in a microchannel tube. The effects of vapor quality, saturation temperature, heat flux, and mass flux on the heat transfer coefficient and pressure ...

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

Advanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

Advanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Rigid Fluorescent Indacenetetraone‐Based Semiconducting Polymers via Knoevenagel Condensation

Advanced Functional Materials, EarlyView.
New donor–acceptor polymers prepared by Knoevenagel condensation of indacenedithiophene‐ and indacenedifuran‐based aldehydes reveal an exceptionally rigid backbone, which is manifested in the remarkably narrow absorption and emission bands in red to near‐infrared region.

Light‐Mediated Photomultiplication via Cascade Energy Transfer in Organic Photodiode

Advanced Functional Materials, EarlyView.
Light‐mediated photomultiplication via cascade energy transfer in organic photodiode demonstrates external quantum efficiency exceeding 200% and specific detectivity surpassing 5.0 × 1013 Jones. This advancement effectively addresses the limitation of elevated dark current density characteristic of prior photomultiplication organic photodetectors ...
