4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Single Fusion Pore Analysis via Single Cell Amperometry Uncovers Impaired Pore Expansion That Restricts Insulin Exocytosis in Human Type 2 Diabetes

open access: yesAngewandte Chemie, EarlyView.
The final step in insulin exocytosis from pancreatic beta cells is the formation of the fusion pore. We combined single‐cell amperometry with microsensors and fluorescence microscopy to monitor insulin exocytosis from different perspectives. Our results reveal a link between impaired fusion pore function and diminished insulin secretion, highlighting ...
