• applied onto the central part of both the Au(111) and a HOPG surface. The total area of wax crystallization was about 20 mm2 for both substrates. The chloroform took ca. 30 seconds to evaporate from the surface leaving the wax molecules on the substrate. The substrates were then fixed to the AFM stainless

• steel base plate, and the first image acquisition started as soon as possible after the chloroform evaporation, typically after 8–10 minutes. AFM images were taken consecutively from the same substrate area over a period of several hours applying a constant scan rate (as denoted in the respective figure

• reaction of commercial ZrO2 with Mg powder was carried out in a closed stainless steel cell, at 750 °C. On completion of the reaction, the additionally formed MgO is removed by treatment with acid. The characterization of the product was performed by XRD, X-ray absorption spectroscopy, SEM, TEM and

In general, a stainless steel cell is filled with a single reactant (or a combination of reactants) and heated at an appropriate temperature under its autogenic pressure. The pressure is generated by the thermal dissociation of reactants and the Let-Lok

Experimental Chemicals, ZrO2, and Mg, were obtained from Aldrich. A 3 mL closed vessel cell was assembled from stainless steel (made by HAM-LET, Israel
