Wetting Interactions Between Porous Carbon Hosts and Liquid Sodium‐Potassium Alloys Toward Their Use in Negative Electrodes of Alkali‐Metal Batteries

Advanced Functional Materials, EarlyView.
Porous carbon host materials are investigated for their possible usage in liquid alkali‐metal negative electrodes. X‐ray computed tomography reveals pore‐filling behavior under various conditions: non‐wetting, forced wetting, and spontaneous wetting. The applicability of porous carbon in electrochemical cells is demonstrated at high areal capacities ...

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

Advanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...
