Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

open access: yesAdvanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Investigation of Partial Discharge in Solid Dielectric under DC Voltage

open access: yes, 2014
A partial discharge, or PD, is defined as an electrical discharge that is localized within only a part of the insulation between two separated conductors. Recent research on PD mainly focuses on the study of PD characteristics under AC voltage.

Hydrophobic Deep Eutectic Solvent (DES) Design Enables Optimally Hydrated DES‐in‐Water Electrolytes for High‐Performance Bromine Redox‐Enhanced Energy Storage Systems

open access: yesAdvanced Functional Materials, EarlyView.
Faradaic charging with bromine redox chemistry shows promise for energy storage, yet its efficient use in aqueous electrolytes is hindered by water decomposition and polybromides' cross‐diffusion, leading to suboptimal cell performance. This study introduces a tetrabutylammonium bromide‐based hydrated deep eutectic electrolyte with optimized water ...
