We need to remove some metal contamination from Au(111). Does anybody have a good and tested recipe for electropolishing Au(111) single crystal?
Could you recommend some articles on Urban Transportation System optimization and Innovation?

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...
