Site‐Selective Polyvinylpyrrolidone Adsorption Behavior for 3D Heterogeneous Integration

open access: yesAdvanced Materials Technologies, EarlyView.
Site‐selective adsorption behavior is presented with polyvinylpyrrolidone on a Cu/SiO2 pattern wafer, which enables 3D heterogeneous integration. Owing to the site‐selective adsorption behavior and its corresponding electrostatic interaction between SiO2 nanoparticles and the Cu surface, the selectivity of Cu/SiO2 is arbitrarily controlled ...

Epithelium‐Inspired, Ultrahigh‐Toughness, Ultralow‐Hysteresis, and Highly Compressible Polymer Hydrogels as Self‐Powered, Visual, and Underwater Strain Sensors

open access: yesAdvanced Science, EarlyView.
Inspired by epithelial tissue, epithelium‐like structure hydrogels are synthesized. The as‐prepared hydrogels exhibit ultrahigh toughness, ultralow hysteresis, and ultrahigh compressibility, which can be utilized as self‐powered and visual strain sensors.

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

Fundamental Aspects of Conduction in Charged ErMnO3 Domain Walls

open access: yesAdvanced Electronic Materials
It is now well‐established that ferroelectric domain walls, at which there are discontinuities in polarization, are usually electrically conducting. Yet, there is a dearth of rather basic information on the physics underpinning conductivity. Here, Kelvin

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels

open access: yesAdvanced Science, EarlyView.
Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...
