Ribbon-Like Nanopattern Formed on Nitrogen-Adsorbed Vicinal Cu(001)

The Structure of Atomic Nitrogen Adsorbed On

Nitrogen atoms adsorbed on a Fe(100) surface cause the formation of an ordered ~(2x2) overlayer with coverage 0.5. A structure analysis was performed by comparing experimental LEED I-V spectra with the results of multiple scattering Todel calculations. The N atoms were found to occupy fourfold hollow sites, with their plane 0.27 A above the plane of the surface Fe atoms. In addition, nitrogen a...

Clostridium spores with ribbon-like appendages.

Spores of Clostridium sp. N1 are characterized by numerous broad ribbon-like appendages attached to one end. The appendages are two to three times the length of the spore and, at their maximal dimension, may be two-thirds the width of the spore. They are attached to the spore body by a common trunk which is continuous with the outer spore coat. Each appendage is a multilayered structure and is ...

Steps or Terraces? Dynamics of Aromatic Hydrocarbons Adsorbed at Vicinal Metal Surfaces.

The study of how molecules adsorb, diffuse, interact, and desorb from imperfect surfaces is essential for a complete understanding of elementary surface processes under relevant pressure and temperature conditions. Here we use first-principles calculations to study the adsorption of benzene and naphthalene on a vicinal Cu(443) surface with the aim to gain insight into the behavior of aromatic h...
