Catalogue of fungi in China 5. Preliminary survey of macrofungi in Medog, Southwest China

open access: yesMycology
The unique ecological environment and minimal human interference in Medog County endow it with abundant and distinctive macrofungi resources. But in the past, there have been few research reports on the investigation of macrofungi in Medog County.

Surface stress of Ni adlayers on W(110): the critical role of the surface atomic structure

open access: yes, 2012
Puzzling trends in surface stress were reported experimentally for Ni/W(110) as a function of Ni coverage. In order to explain this behavior, we have performed a density-functional-theory study of the surface stress and atomic structure of the ...

Metallic clusters on a model surface: quantum versus geometric effects

open access: yes, 2011
We determine the structure and melting behavior of supported metallic clusters using an ab initio density-functional-based treatment of intracluster interactions and an approximate treatment of the surface as an idealized smooth plane yielding an ...

The electronic structure of the Na$_x$CoO$_2$ surface

open access: yes, 2008
The idea that surface effects may play an important role in suppressing $e_g'$ Fermi surface pockets on Na$_x$CoO$_2$ $(0.333 \le x \le 0.75)$ has been frequently proposed to explain the discrepancy between LDA calculations (performed on the bulk ...

Plastic covering on airfoil structure provides smooth uninterrupted surface [PDF]

open access: yes, 1975
Primed surface is covered with adhesive. Sheet of plastic film is stretched over adhesive and mechanical holder is used to apply tension to ends of sheet to make it conform to surface of airfoil.
