Spacedaily is reporting (here) that scientists have managed to bond oxygen to platinum breaking through the so-called "oxo-wall". One must ask, given the catalytic properties of platinum and the reactive propensity of oxygen, what could an oxo-platinum tipped Fine Motion Controller (or SPM) do?
Consideration of higher molecular weight elements is largely lacking in Nanosystems. Yet most elements from iron to uranium have some very interesting properties at the nanoscale level. Should these not be explored in more detail?
