A surface-enhanced Raman scattering (SERS) active structure allows the highly sensitive imaging of label-free molecular trace. gold nanostructure with boehmite as a skeleton was fabricated by inclined magnetron sputtering method. The characteristics prepared SERS plate consisting on were evaluated follows. distance dependence intensity 4,4′-bipyridine from edge substrate indicated that larger b...

The adsorption of oxygen molecules on ytterbium nanofilms various thicknesses has been studied by X-ray photoelectron spectroscopy and contact potential difference measurements. It established that the maximum number O 2 can be adsorbed films increases with film thickness. Such behavior is observed at less than 10 monolayers. This size effect ultimately due to fact an indispensable condition fo...

Shear-based material removal processes significantly influence the quality of workpiece surface and implicitly component functional performance. An in-situ SEM nano-cutting enabled study crystal flow lattice rotation occurring below cutting edge in a polycrystalline Nickel superalloy. When within single grains deformed nanolayer appears that consists rotated exclusively plane which is delimited...
