We produced single-crystalline Fe nanodot arrays grown in situ on a W(110) substrate in an ultrahigh vacuum system. An alumina shadow mask with perfectly ordered holes was used for Fe deposition. Polycrystalline Fe nanodots could be crystallized to single-domain nanodots by thermal annealing. After annealing, Fe wets tungsten substrate with one monolayer, but Fe islands neither coalesce nor form an alloy with the substrate.

    By using superoleophobic alumina and low vapor pressure oils we have been able to study wetting behavior at high vacuum. Here, we show that a superoleophobic state can exist for some probe liquids, even under high vacuum. However, with other liquids the surfaces are only superoloephobic because...

    The design of a cold finger and sample holder for use with a long-strong XYZ manipulator in a multitechnique ultrahigh vacuum chamber is presented. The cold finger design, based on the concept of a cryogenic transfer line, minimizes unwanted cryosorption on the surface of the cold finger. The...

    We demonstrate that thermocapillary forces may drive bubbles against liquid flow in 'anomalous' mixtures. Unlike 'ordinary' liquids, in which bubbles migrate towards higher temperatures, we have observed vapour bubbles migrating towards lower temperatures, therefore against the flow. This...

    The surface tension of liquid francium is evaluated in a wide temperature range, from its melting point to 800 K, using the correlation between the surface tension of alkali metals (full electronic analogs) and the universal parameter tan a in Prikhod'ko's system of unpolarized ionic radii.
