oxygen evolution

[/ˈɑːksɪdʒən ɪˈvɑːluːʃən/]
noun
evolução do oxigênio
1. The process by which oxygen gas is produced, typically as a byproduct of photosynthesis or electrochemical reactions
Oxygen evolution occurs in the light-dependent reactions of photosynthesis when water molecules are split.
A evolução do oxigênio ocorre nas reações dependentes de luz da fotossíntese quando as moléculas de água são divididas.
2. In electrochemistry, the oxidation reaction at an electrode that produces gaseous oxygen
The oxygen evolution reaction is a critical step in water electrolysis.
A reação de evolução do oxigênio é uma etapa crítica na eletrólise da água.
3. In photobiology, the release of O₂ gas from photosynthetic organisms during light reactions
Cyanobacteria are known for their efficient oxygen evolution in aquatic environments.
Cianobactérias são conhecidas por sua evolução eficiente de oxigênio em ambientes aquáticos.
This is technical scientific terminology used universally in academic and research contexts in both Brazil and the USA. It is particularly important in the study of photosynthesis, water electrolysis, and renewable energy research. The term is standardized across international scientific literature and does not vary significantly by region, though it is primarily used by scientists, engineers, and students in STEM fields.
