Phosphorus is an exciting element: It is essential for the survival of organisms and promises numerous electronic applications. With this in mind, researchers at the University of Basel have synthesized two-dimensional layers containing rings of five phosphorus atoms (phosphorus pentamers (cyclo-P5)) on a silver surface.

For the first time, they have been able to investigate their electronic properties using combined atomic force and scanning tunneling spectroscopy. They found that the atomic phosphorus pentamer layer retains its semiconductor properties and forms a special electronic interface where the layer joins the silver surface (p-type semiconductor-metal Schottky junction).

This shows that phosphorus pentamers on the silver surface fulfill a basic requirement for applications in field-effect transistors, diodes or solar cells, as recently reported by the research team in the scientific journal Nature Communications (“Probing charge redistribution at the interface of self-assembled cyclo-P5 pentamers on Ag(111)”).

Professor Donald Hoffman is a cognitive neuroscientist and the author of more than 90 scientific papers and three books, including Visual Intelligence and The Case Against Reality.

He is best known for his theory of consciousness, which combines evolutionary theory with mathematics to make a compelling case that the reality we see every day is an illusion created by our minds.

In this conversation, we explore:

— The groundbreaking scientific research being conducted by physicists into the “structures” beyond spacetime.

Stress sensitive neural circuits change the gut microbiome and the duodenal glands.

Precision mapping of a gut-brain circuit w/ functional impact.

Glands in the small intestine (Brunner’s) have GLP-1 receptors, are stress-sensitive, connect to the brain via the vagal nerve, modulate bacterial…


Stress leads to disarray of the gut microbiome, which in turn causes inflammation and a drop in the body’s ability to fend off infection.
