Advanced Healthcare Materials, EarlyView.Dementia syndrome affects millions of people in the world, and Alzheimer's disease (AD) is the most common cause. We report the detection of the specific biomarker for AD, p‐tau‐181, from physiological to pathological concentrations in cerebrospinal fluid using an electrolyte‐gated organic transistor biosensor.

Thorium- and uranium-mediated C-H activation of a silyl-substituted cyclobutadienyl ligand
, 2022 Cyclobutadienyl complexes of the f-elements are a relatively new yet poorly understood class of sandwich and half-sandwich organometallic compounds. We now describe cyclobutadienyl transfer reactions of the magnesium reagent [(?4-Cb'''')Mg(THF)3] (1 ...

Sub‐Nanometer Curvature Unlocks Quantum Orbital Flexoelectricity in Graphene
Advanced Materials, EarlyView.In self‐assembled, reproducible, large‐area, quasi‐pristine graphene nanowrinkles, extreme curvature forces out‐of‐plane π‐electrons toward hybridization, driving a transition from classical to quantum orbital flexoelectricity. As curvature approaches the fundamental physical limit set by the C─C bond length, the resulting polarization increases by ...
