Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging

Advanced Functional Materials, EarlyView.
Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

Advanced Functional Materials, EarlyView.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...
