Polystyrene microplastics alter the accumulation and elimination dynamics of silver nanoparticles in Daphnia magna

Environmental context Microplastics are widespread aquatic contaminants that can alter the environmental behavior of co-occurring pollutants. This study shows that polystyrene microplastics substantially modify silver nanoparticle bioaccumulation in Daphnia magna, increasing wate...

Collective FluidCoupling in Ultrathin Covalent OrganicFramework Membranes for High-Performance Electrokinetic Energy Harvesting

Abstract Nanofluidic membranes hold promise for hydroelectric energy harvesting, but their output power is often limited by high fluidic impedance. Here, we fabricate ultrathin covalent organic framework (COF) membranes with AA-stacked, regular nanopore arrays. These membranes ex...

Disentangling surface and bulk properties of Ta3N5 photoanodes

Abstract Understanding how material and defect characteristics govern photoelectrochemical performance is essential for developing efficient and stable photoelectrodes. Although bulk properties are often emphasized, surfaces and interfaces can equally determine activity and stabi...

In situ Second-HarmonicGeneration Probing of Magnetic-Field-InducedChiral Stacking in a Radical-Doped Liquid Crystal Monolayer

Abstract Functional open-shell π-radicals offer attractive optical and magnetic tunability but suffer from poor ambient stability, limiting their deployment in condensed-phase architectures. Here we circumvent this limitation by embedding the photolabile radical precursor HTTM-PD...

Narrowband and wavelength-tuneable bright EUV–soft-X-ray harmonics for resonant imaging and spectroscopy

Abstract Ultrashort, bright, wavelength-tuneable X-ray pulses are essential for resonant imaging and spectroscopy, yet are typically available only at large-scale free-electron-laser facilities. In this study, we present an efficient tabletop technique for generating wavelength-t...
