Biomimetic calcium-inactivated ion/molecular channel

A phosphopeptide-modified nanochannel was prepared based on a conical polymeric nanopore. It shows a reversible Ca2+-induced inactivation effect toward the ion flow and molecular transport, resulting from Ca2+ binding-caused surface...

Signature of a conical intersection in the dissociative photoionization of formaldehyde

Electron/ion coincidence experiments and ab initio calculations of the dissociative photoionization of formaldehyde reveal the presence of a conical intersection controlling the dynamics and favoring dissociation into the molecular channel, CO+ + H2.
