Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

open access: yesAdvanced Materials Interfaces, EarlyView.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

open access: yesAdvanced Materials Interfaces, EarlyView.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...
