Abstract: Polypyrrole (PPy)/carbon (C) composites were synthesized by oxidative chemical polymerization and used as support material for Pt nanoparticles. PPy/C supported Pt nanoparticles were prepared by using a promising catalyst preparation method, supercritical carbon dioxide (scCO 2 ) deposition. The prepared materials were characterized by using BET, TGA, XRD, and TEM techniques.

Its sulfur dioxide (SO 2 ) and carbon dioxide (CO 2 ) emissions are relatively high due to the electricity production, this sector is still heavily relying on coal. This study investigates the electricity sector in Morocco and its production sources, it highlights the limitations of the current model and gives an opportunity analysis to meet the carbon neutrality target.

History of cardiac output measurement from carbon dioxide elimination. One of the oldest non-invasive techniques for measure- ment of cardiac output is the Differential Fick method using measurement of carbon dioxide (CO 2 ) elimination.. Caco 2 can be estimated non-invasively by measurement of alveolar or end-tidal CO 2 partial pressure P E ' CO2 with knowledge of the solu- bility coefficient s of CO 2 in blood.

As of April 2020, 61 explicit carbon pricing initiatives have been implemented or scheduled for implementation at regional, national or sub-national jurisdiction levels. These carbon pricing initiatives covered 12 gigatonne of carbon dioxide equivalent (GtCO 2 e), or about 22% of global GHG emissions, with carbon price ranging from less than USD1 to around USD120 per tonne of carbon dioxide equivalent (/tCO 2 e).
