Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

A Quasi‐Solid Ionic Liquid‐Polymer Hybrid Electrolyte for Shuttle‐Free and Dendrite‐Free Aqueous Zinc─Bromine Batteries

Advanced Materials, EarlyView.
A quasi‐solid ionic liquid‐polymer hybrid electrolyte is proposed to achieve shuttle‐free and dendrite‐free aqueous Zn─Br batteries. Synergetic effects between Zn2+ selective conduction of polyanionic network and polybromide complexing additive suppress the shuttle effect and improve Zn reversibility.

Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

Advanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Universal Fluorine‐Free Proton Exchange Polymers for High‐Performance and Durable Fuel Cells Operable Under Severe Conditions

Advanced Materials, EarlyView.
Due to excellent physical and chemical stability, the novel designed fluorine‐free polymers with aliphatic‐chain backbones (SP‐PAC12‐QP) are regarded as promising and universal alternatives to perfluorosulfonic acid membranes. Their performances are further improved by physical reinforcement, where the fuel cell performance under high temperature and ...

Fatigue Tensile Testing of Glass Fiber-Reinforced Polymer Reinforcing Bars

SSRN Electronic Journal, 2022
Glass fiber-reinforced polymer (GFRP) bars are a valid alternative to traditional steel bars for reinforcing concrete structures in specific situations. Although the elastic modulus of GFRP bars is generally 20–25% of that of steel bars, which entails for a higher cross-sectional area of GFRP than of steel bars for the same axial stiffness, they have ...

Failure of Polymer Beams Reinforced with Glass Fibers

Mechanics of Composite Materials, 2020
The present paper deals with the four-point bending of polyvinyl chloride beams reinforced with glass fiber clusters. The clusters, treated as orthotropic materials, were arranged periodically along the longitudinal axis of beams. The load-carrying capacity of the beams was estimated by two methods.

Concrete Columns Reinforced by Glass Fiber Reinforced Polymer Rods

SP-188: 4th Intl Symposium - Fiber Reinforced Polymer Reinforcement for Reinforced Concrete Structures, 1999
A total of 15 concrete columns were cast and tested to investigate the influence of replacing longitidunal and/or tie steel bars by an equal volume of amount of glass fiber reinforced polymers (GFRP) bars on the behavior of concrete columns. The columns were subjected to concentric monotonic axial loading.
