An inert atmosphere refers to a surrounding with no reactive or active elements or gases. It is a place where chemical reactions or fires cannot easily occur due to the absence of oxygen or other reactive substances. Full definition
We will start with a theoretical radiatively inert atmosphere which will still have undulations at the tropopause due to uneven surface heating below but they will be minimal and so for all intents and purposes the rising and falling columns will both follow the dry adiabatic lapse rate as they move up and down: (newclimatemodel.com)
Their convenient and practical preparation entailed template assembly of cobalt - diamine - dicarboxylic acid metal organic frameworks on carbon and subsequent pyrolysis under inert atmosphere. (science.sciencemag.org)
Finally, the strain effect is dominant in inert atmosphere and strongly sensitive to the kinetics of treatment. (european-mrs.com)
