Carbaminohemoglobin unloads the carbon dioxide in the lung, where the Pco2is lower. The process of carbon dioxide loading and unloading is facilitated by the Haldane effect; the binding of oxygen with hemoglobin displaces carbon dioxide and hydrogen ions from the hemoglobin. The concept of the H...
Carbon dioxide (chemical symbol CO2) is a colorless, acidic gas with a density approximately 53% more than that of dry air CO2molecules are formed via a covalent double bond between a carbon atom and two oxygen atoms. It occurs naturally as a trace gas in the Earth’s atmosphere. Volcanoes...

The adsorption of carbon monoxide, carbon dioxide, argon and nitrogen on two types of nickel catalyst have been studied. On one of these catalysts it appears that more than one-third of the nitrogen adsorption at -195° is chemisorption. This complicates the classical procedure for studying carb...
Oceanic absorption of CO2 is one of the most important forms of carbonsequesteringwhich limit the human-caused rise of carbon dioxide in the atmosphere. However, this process is limited by a number of factors. CO2 absorption makes the water more acidic, which affects ocean biosystems. The projec...

In summary, the ligand-free Pt NPs with a size ranging from 1.8 to 7.0 nm dispersed well on the HTSO have been successfully realized. The size manipulation of Pt NPs was achieved by adjustment of the nucleation amounts through the addition of acidic or basic additives, and the ABAR ...
Supercritical carbon dioxide (CO2) is well established for use as a processing solvent in polymer applications such as polymer modification, formation of polymer composites, polymer blending, microcellular foaming, particle production and polymerization. Its gas-like diffusivity and liquid-like density in...
