Investigating the Mechanism of Ion Concentration Polarization Within Nanofluidic Hydrogel Membranes: Experiment and Simulation

Advanced Materials Interfaces, EarlyView.
Molecular dynamics simulations are employed to model ion concentration polarization (ICP) at the nanoscale, revealing fundamental electrokinetic behaviors that align with experimental observations. The study demonstrates how membrane charge, ionic strength, and electric fields affect ion localization and biomolecule trapping, providing mechanistic ...

Interfacial Effects and Negative Capacitance State in P(VDF-TrFE) Films with BaTiO3 Nanoparticles [PDF]

arXiv
We analyze the temperature dependences of the effective dielectric permittivity of P(VDF-TrFE) films with BaTiO3 nanoparticles (with the average size 24 nm). Transition from a weak to a strong nonlinear temperature dependence of the dielectric permittivity is observed near the freezing temperature (near -50 {\deg}C) of P(VDF-TrFE).

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...

Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption

Advanced Materials Interfaces, EarlyView.
The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...
