Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption

open access: yesAdvanced Functional Materials, EarlyView.
Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

open access: yesAdvanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...
