Earlier work on condensation phenomena is briefly reviewed, and existing measurements of condensation energies are summarized. Measurements of condensation energies have been made for aluminium, silver and cadmium on glass and for aluminium and silver on single-crystal cleavage surfaces of sodium chloride and potassium bromide. Adhesive energies or binding energies between film and substrate have been calculated in each case. Association energies for nucleation are obtained by difference and shown to be consistent. Results for cadmium show good agreement with earlier work, but results for aluminium do not agree with the earlier results of Rhodin who measured the condensation energies for aluminium on various substrates, obtaining values which suggest chemisorption. These results appear to be too high and a possible explanation is given. It is concluded that the adhesive energy is due to physical adsorption and can be explained in terms of van der Waals forces only.

Replica studies of a freshly-cleaved surface of a NaCl single crystal which had been treated for 15 seconds with a relatively impure (bulk) methanol revealed the presence of a large number of three-dimensional oriented overgrowths having cubic symmetry (Fig. 1). Attempts to reproduce such morphological surface phenomena about 6 months later with the same methanol were not successful, possibly due to “aging” of the methanol. Treatment for 15 seconds with A.C.S. methanol did not result in any significant surface morphology. So far, the nature of the impurity in the bulk methanol has not been identified; however, analyses indicate that it is present in an amount less than 0.15%. All surface treatments of NaCl were followed by a 5-second rinse in A.C.S. acetone and another 5-second rinse in petroleum ether (Skelly B). Neither rinse contributed to surface morphology. Freshly cleaved NaCl surfaces were also treated with 1.25% by weight of A.C.S. NH4Cl in A.C.S. methanol and 1.36% by weight of U.S.P. 37% formaldehyde-water-methanol solution in A.C.S. methanol.

The use of a sodium in sodium chloride dispersion is systematically evaluated for the synthesis of nickel(0) and nickel(I) complexes from readily-prepared nickel(II) precursors. A variety of complexes with phosphine and bipyridine-type ligands were accessed, although some reactions were found to produce mixtures of nickel(0) and nickel(I), and yields were highly variable. Several new nickel(I) complexes were obtained, and these were characterised using techniques including NMR spectroscopy, EPR spectroscopy, and single crystal X-ray diffraction analysis.
