Advanced Functional Materials, EarlyView.A novel proquinoid‐type electron acceptor, TQC‐4Cl, with an ultra‐narrow bandgap of 1.01 eV and spectral response beyond 1200 nm enables organic SWIR photodetectors. The optimized devices show a high EQE of 13.66% and high specific detectivity over 1012 Jones at 1200 nm under −0.5 V reverse bias with outstanding thermal stability, highlighting their ...

Advanced Functional Materials, EarlyView.Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Isthmus Dependent Atrial Flutter Cycle Length Correlates with Right Atrial Cross-Sectional Area
Indian Pacing and Electrophysiology Journal, 2009 Background: Right atrial flutter cycle length can prolong in the presence of antiarrhythmic drug therapy. We hypothesized that the cycle length of right atrial isthmus dependent flutter would correlate with right atrial cross-sectional area measurements.

Advanced Healthcare Materials, EarlyView.Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Magnetic Bioprinting and Actuation of Stretchable Muscle Tissue
Advanced Healthcare Materials, EarlyView.Human and murine myoblasts labeled with iron oxide nanoparticles are magnetically bioprinted into wrench‐shaped tissues, which are then anchored between two magnetic needles. Mechanical stretching of these tissues enhances both their maturation and functional performance. Abstract Engineering tissues with precise, long‐lasting shapes and the capability
