(28) reported that the intrinsic fluorescence of protein is mainly contributed by the Trp residue alone, the Phe residue has a very low quantum yield and the fluorescence of Tyr is almost totally quenched
when it is ionized.
This probability is equal to the fraction W of the excited fluorophore molecules that are quenched
Compared with the fluorescence quenching of anthracene by MAH ([K.sub.sv], = 87L/mol) (6), fluoranthene is more quenched
by MAH due to its longer lifetime of around 50 ns (16) compared with 6 ns for anthracene.
The density of generated FE mesh is considerably higher along quenched
Four of the 25 compounds evaluated in this study fluoresced or quenched
sufficiently to confound the fluo rescence-based screening assays used in this study.
As soon as tool steels have been quenched
to about 125/150F, they should be immediately tempered.
In Figure 1, the quenched
PD3 rail sample has the maximum hardness and the hot-rolled U71Mn rail sample has the minimum hardness before the test.
For example, quenched
martensite in the carburized surface contains more carbon compared to the deeper volumes; therefore, surface martensite has bigger comparative volume and is formed from the smaller plates.
They showed that fluorescence emission is more quenched
by trinitrotoluene (TNT) than by dinitrotoluene (DNT) in chloroform solution.
When austempering, components are quenched
from the austenitizing temperature to a temperature above the martensite start temperature (M) and then held for a time sufficient to form the desired microstructure (ausferrite).
