Definition of photochemical in English:

photochemical

adjective fəʊtə(ʊ)ˈkɛmɪk(ə)lˌfoʊdoʊˈkɛmɪk(ə)l

1Relating to or caused by the chemical action of light.
光化（学）作用的；光化（学）作用引起的
a photochemical reaction
Example sentencesExamples
- The small rings are made to move around the big ring by bathing them in light of different wavelengths; the light energy fuels the photochemical reaction to break the hydrogen bonds.
- This is a problem for museums because photochemical oxidation is not required; the reactions take place in the dark.
- One influential school of thought focuses on the effects of oxidation reactions brought about by active oxygen species generated by photochemical reactions involving blue and UV light.
- Photoproduct levels may reflect the net photochemical effects of light and oxygen within tissue on native photosensitizers.
- In addition, the carrier molecule may also protect some dyes from chemical, photochemical or radiolytic degradation.
1. 1.1 Relating to photochemistry.
  （与）光化学（有关）的
  Example sentencesExamples
  The program emphasized photochemical approaches, although thermochemical processes were also evaluated.
  Ever since mechanical and photochemical advances in the 19th century gave rise to the invention of motion picture recording and display, the evolution of the ‘art’ of film has been a consequence of the rate of technological change.

Derivatives

photochemically

adverb

Lawton had previously demonstrated that the diazopyruvoyl group could be used as a photochemically active precursor for covalent attachment of labeling and cross-linking agents to proteins containing nucleophilic sites.
Example sentencesExamples
- During the oxidative stress of constant ultraviolet radiation, at least one photochemically active tryptophan metabolite, N-formyl kynurenine (NF-Kyn), is formed in the lens.
- In the photogravure process, the image is photochemically transferred to an etching plate that has been coated with a light-sensitive emulsion.
- The light-stimulated uptake of ammonium, for instance, indicates the involvement of the enzyme glutamate synthase, which, in many other photosynthetic systems, is driven by photochemically derived reduced ferredoxin.
- In addition and parallel to drug photobleaching during PDT, native photosensitizers can be photochemically converted to new species known as ‘photoproducts’.

Rhymes

academical, agrochemical, alchemical, biochemical, chemical, petrochemical, polemical
