Réduction catalytique sélectiveLa réduction catalytique sélective (RCS) (en anglais selective catalytic reduction (SCR)), est une technique utilisée pour réduire les oxydes d'azote (NO) émis soit par des moteurs à combustion interne, soit par des installations industrielles de combustion : gaz, charbon et pétrole. Cette technologie est également utilisée pour réduire les émissions de NO de chaufferies biomasse ou d'incinérateurs de déchets non dangereux.
Hydrothermal synthesisHydrothermal synthesis includes the various techniques of crystallizing substances from high-temperature aqueous solutions at high vapor pressures; also termed "hydrothermal method". The term "hydrothermal" is of geologic origin. Geochemists and mineralogists have studied hydrothermal phase equilibria since the beginning of the twentieth century. George W.

High dynamic rangeHigh dynamic range (HDR) is a dynamic range higher than usual, synonyms are wide dynamic range, extended dynamic range, expanded dynamic range. The term is often used in discussing the dynamic range of various signals such as s, videos, audio or radio. It may apply to the means of recording, processing, and reproducing such signals including analog and digitized signals. The term is also the name of some of the technologies or techniques allowing to achieve high dynamic range images, videos, or audio.
