However, the aldehyde group on the oxidized dextran makes it has the ultraviolet absorption
. It is mainly the formation of hydrate between aldehyde groups and H2O molecules after oxidized process.
Figure 5b shows the ultraviolet absorption
spectra of the feed solution with reaction time.
The analytical methods for characterization of the base stock oils used in mineral lubricants (aromatic, naphthenic and paraffinic) include the identification of aromatic compounds by ultraviolet absorption
from 260 to 350 nm.
Low-Pass Filter by Nonlinear Ultraviolet Absorption
Effects in SiQDs.
It uses ultraviolet absorption
of unstained cells which is cost effective, can be done in real time, and can have a higher confidence level of accuracy.
Bagge, who chatted with readers about her work in the comment section of the story on the Science News website, responded: "These shrimp are transparent in the visible spectrum, but I do not know if anyone has yet measured the ultraviolet absorption
of the tissues of these specific shrimp.
Ozone is currently measured by the ultraviolet absorption
, the iodine titration , the indigo dye [3, 4], or the galvanic method .
Nanodiamonds have received a lot of interest as a semiconductor material, due to their strong ultraviolet absorption
and high thermal conductivity.
Thus, along with the origin of the superrotation of the atmosphere, identification of a mysterious source of ultraviolet absorption
in the clouds, Venus polar vortices are one of the great mysteries of our twin planet.
A jump of the ultraviolet absorption
edge (around 380 nm) from blue shift to red shift can be clearly observed as the doping concentration increases.
Ozone measurement is controlled by a reliable DM100 ozone unit, which employs the ultraviolet absorption
Other techniques, such as ultraviolet absorption
and chemiluminescence, are also used when concentrations are low," says Graham.
