... pying their respective trap sites. Typically, the more efficient and strongly trapped oil droplet won out in this competition. This size effect may be understood from a consideration of the spatial separation of the two trap sites. A HGS, trapped at z trap 5 22.21R p , is displaced roughly one parti ...

The problem of light leakage along the cone of the tip is not necessarily critical for imaging in the nearfield, since this leaking light has a poor lateral confinement and just adds a background to the near-field image. But for applications based on ph ...

Ultraviolet–visible spectroscopy



Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
