Parameter-Free Coordination Numbers

After a lot of hard work, the second article of Ruben has been published in the Journal of Chemical Physics. The scheme, called ASANN, provides robust coordination numbers for solid-liquid interfaces and metal (alloy) nano-particles and surfaces.

The picture below reports the cation distribution and coordination at a graphite electrode of about -2.5 V vs. SHE. ASANN resolves that Cs+ is partially desolvated at the interface, while Na+ is not.

Mind the gap!

Our collaborative work on the pressure gap of methane thiol adsorption on Au(111) is online. The high-pressure (1 bar), high temperature (~400 K) STM work and its simulations have been a real challenge, but the joint interpretations have allowed to identify a phase transition upon increasing the pressure compared to the commonly observed low pressure structures.
