2D Phosphorene‐Decorated Ni‐Rich Layered Cathodes for High‐Power and High‐Energy Li‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A conformal coating of 2D phosphorene nanosheets is decorated on Li[Ni0.8Co0.1Mn0.1]O2 cathodes to enhance fast charge–discharge performance and structural stability under high mass loading and low carbon content. As a result, it exhibits improved power capability, cycle stability, and suppressed structural degradation, offering a promising strategy ...

Transparent Inorganic–Organic Bilayer Neural Electrode Array and Integration to Miniscope System for In Vivo Calcium Imaging and Electrophysiology

open access: yesAdvanced Functional Materials, EarlyView.
This study presents the BioCLEAR system, a highly transparent and conductive neural electrode array composed of silver nanowires (AgNWs) and doped PEDOT:PSS, enabling neural recordings with minimal optical artifacts. When integrated with a GRIN lens, this cost‐effective neural implant allows simultaneous electrophysiological recording and GCaMP6‐based ...
