Atomic-scale ion transistor could lead to better brain–computer interfaces

Physics World

An atomic-scale ion transistor that achieves the ultrafast opening and closing of ion channels to specific ions has been developed by researchers in China and the US. They filled the feed solution with equal concentrations of potassium chloride, caesium chloride and lithium chloride and varied the gate voltage. Ion selectivity.

The team hypothesizes that the boundary between these two regions within a cloud represents the transition between atomic neutral gas in the outer envelope, and the cold molecular gas required to form stars in the inner zone. The Radcliffe Wave. The findings are published in The Astrophysical Journal and The Astrophysical Journal Letters.
