Backbone‐Controlled Ion‐Side Chain Accessibility in Conjugated Polymers for Organic Electrochemical Synaptic Transistors

Advanced Functional Materials, EarlyView.
Backbone modulation in glycolated conjugated polymers governs ion accessibility to side chains, strengthes anion adsorption, and suppresses back‐diffusion. As the number of thiophene units increases, structural reorganization, retention, and synaptic plasticity are enhanced, leading to improved neuromorphic performance in electrolyte‐gated organic ...

Ammonium compounds in stratospheric aerosols [PDF]

Tellus B: Chemical and Physical Meteorology, 1986
The circumstances under which morphological examination can provide a reliable guide to thecomposition of stratospheric particles are discussed. It is then shown that while stratosphericparticles often consist largely of sulfuric acid, there are occasions when ammoniated aerosols arepresent.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Multimodal Perception and Machine Learning‐Empowered Human Machine Interfaces With Double‐Network Hydrogel Fibers

Advanced Functional Materials, EarlyView.
This work develops polyacrylamide‐alginate (PAM‐Alg) double‐network hydrogel fibers for multimodal perception and intelligent human‐machine interfaces. The covalent‐ionic network provides high strength, toughness, and stable conductivity. Easily woven into wearables and integrated with soft robots, the fibers enable object and temperature recognitions ...

Dynamic Interfacial Chemistry of Choline Chloride as Electrolyte Additive for Stable Zn‐Iodine Batteries

Advanced Functional Materials, EarlyView.
Choline chloride (ChCl) additive enables dynamic interface engineering in Zn‐I2 batteries by forming hydrophobic polyiodide complexes and a Zn‐stabilizing Ch+‐rich layer under electric field modulation. This dual‐function strategy suppresses iodine hydrolysis and dendrite formation, while optimizing Zn2+ solvation and transport for high‐efficiency ...

Extremely Long Electron Lifetime in Spontaneously Passivated Polycrystalline Perovskite Layers via Illumination‐Assisted Trap Filling

Advanced Functional Materials, EarlyView.
ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|
