Calorimetric measurement of adsorption and adhesion energies of Cu on Pt(111)

- First measurement of adsorption energy for any metal-on-metal combination that forms a bulk alloy.
- Heat of adsorption and adhesion energy for Cu on Pt(111).
- Cu monolayer 12 kJ/mol more stable than Cu(solid), vs 83 in underpotential deposition.
- Lattice strain causes decrease in heat with coverage.
