2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

Advanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Effect on Particle Deposition Characteristics and Air-side Pressure Drop of Fin-and-tube Heat Exchangers under Dehumidifying Conditions

Zhileng xuebao, 2018
Fin-and-tube heat exchangers are widely used in indoor units of air conditioners. When the indoor unit heat exchanger is served as evaporator, dehumidification may occur on the fin surface and dust particles easily adhere to the wet fin surface, leading ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

Advanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Dual‐Layer Conducting and Redox Polymer Bioanodes for Synergistic Enhancement of Microbial Extracellular Electron Transfer

Advanced Functional Materials, EarlyView.
A hybrid PEDOT/Fc‐LPEI conducting/redox polymer bioanode synergistically improves microbial extracellular electron transfer (EET) in Shewanella oneidensis MR‐1. The dual‐layer interface delivers 18‐fold higher current output and 27‐fold greater charge collected than bare carbon felt, highlighting an effective strategy for high‐performance ...
