Hybrid Ferroelectric Tunnel Junctions with Intrinsic Nonlinearity and Self‐Rectification via Interfacial Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Rapid thermal annealing reconstructs the BCFO/Nb:STO interface into an atomically thin reconstructed interfacial layer, which reshapes the tunneling barrier and converts a high‐TER ferroelectric tunnel junction into an intrinsically nonlinear, self‐rectifying device.

Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

open access: yesAdvanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,
