Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

open access: yesAdvanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

High Energy Photon Induced Defect Engineering in Ultra‐Thin Indium Oxide Transistors for BEOL‐Compatible Logic Circuits

open access: yesAdvanced Materials Interfaces, EarlyView.
Xenon flash lamp annealing modulates oxygen‐vacancy states in 1‐nm‐thick ALD In2O3 transistors within a single 139 µs pulse. The photon‐induced defect engineering shifts the threshold voltage, improves bias‐stress stability, and narrows device‐to‐device variation across 64 devices. Combining pristine and treated transistors yields NMOS inverters with a

Hybrid Roll‐To‐Plate Printed CMOS Logic Circuits Via an Integrated Gravure‐Flexographic Printing Strategy

open access: yesAdvanced Materials Interfaces, EarlyView.
A layer‐specific hybrid gravure–flexographic printing strategy enables fully printed SWCNT thin‐film transistors and CMOS logic circuits on flexible substrates. Flexographic printing forms the thin gate and drain‐source electrodes with defined edges, whereas gravure printing forms the uniform dielectric, semiconductor, and doping layers. The integrated
