Astrocyte-Mediated Neuronal Synchronization Properties Revealed by False Gliotransmitter Release [PDF]

, 2017
Astrocytes spontaneously release glutamate (Glut) as a gliotransmitter (GT), resulting in the generation of extrasynaptic NMDAR-mediated slow inward currents (SICs) in neighboring neurons, which can increase local neuronal excitability. However, there is

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Degradation Mechanisms Associated with Electron‐Blocking Layers in Inverted Perovskite Solar Cells

Advanced Science, EarlyView.
The effects of the three typical EBLs NiOx, PTAA, and 2PACz on the photovoltaic performance and degradation mechanisms are investigated under light soaking and solar‐thermal cycling conditions of corresponding PSCs, demonstrating that 2PACz is the best EBL due to the better interface contact and lower lattice distortion.
