Exempel på photochemical

• The processes that pose the greatest risk to the embryo are photothermal and photochemical in nature.

• Two further photochemical turnovers provide the manganese cluster with a total of four oxidizing equivalents, which are used to oxidize two water molecules to dioxygen.

• Photochemical effects, on the other hand, develop when a release of high energy causes bonds to dissociate.

• First, we run the photochemical tracer/transport model on exogenous pollution scenarios.

• He focused mainly on the photochemical procedure that made such a recording possible.

• Nonetheless, the photochemical reaction undergone by the whelk mucus has always occurred, and this suggests that such variations may have been slight.

• Another form of variation is the following of the kinetics of a particular photochemical reaction of the acceptor, which is sensitized by the energy transfer.

• A photochemical technique to enhance sensitivity of detection of fluorescence resonance energy transfer.

• For the amino acids, the main photochemical degradation process has been shown to be decarboxylation, whereas decarbonylation was observed for peptides.

• Therefore, photochemical alterations in only a fraction of them do not disturb their biological function significantly.

• These data will allow us to construct photochemical models, in order for them to be more realistic.

• These pigment-protein complexes carry out the initial photochemical electron-transfer reactions of plants and photosynthetic bacteria.

• The remainder of the presentation will focus on the photochemical evolution of these materials and astrobiology.

• This assumption can break down in photochemical reactions and other very fast processes that are started impulsively.

• The sulphur haze is contentious on photochemical grounds.
