Diverse Cation Exchange in Layered Titanate Nanostructures for Tailored Catalysis

open access: yesAdvanced Materials, EarlyView.
H+(H3O+)‐intercalated layered titanate enables stable intercalation of 42 single‐metal and multication combinations. Alkali‐metal intercalation tunes Rh charge density, yielding an efficient propylene hydroformylation catalyst. These results establish a generalizable intercalation platform for rational catalyst design and provide a library supporting ...

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

open access: yesAdvanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.
