Registered charity number: 207890 Demonstrating a study on the trapping of isotopic carbon dioxide from seasonal ambient air in clay nanotubes by Dr Subhra Jana at the S. N. Bose National Centre for Basic Sciences. Moisture induced isotopic carbon dioxide trapping from ambient air Novel clay-based nanocomposites have been fabricated to capture isotopic CO 2 ( 12 C 16 O 2 , 13 C 16 O 2 , and 12 C 16 O 18 O) from seasonal ambient air as well as to explore the underlying adsorption mechanism, keeping an eye on the relative humidity-induced CO 2 adsorption efficacy of these nanotubes in an oxidative environment.
