Polymerizations in supercritical carbon dioxide

Article Abstract:

Several studies have been carried out to analyze the function solubility supports in the synthesis of polymers in supercritical fluids. Experimental results have significantly advanced the use of supercritical carbon dioxide as an alternative solvent for polymerizations. In addition, several novel aspects of supercritical carbon dioxide have been determined. These include the customization of solvent quality by pressure changes and preparation of materials supporting different morphologies and characteristics.

Occurrence of holes in ternary fluid multiphase systems of near-critical carbon dioxide and certain solutes

Article Abstract:

A study was conducted to analyze the occurrence of holes in ternary fluid multiphase systems of near-critical carbon dioxide and some solutes. The phase behavior of binary mixtures of carbon dioxide was examined. Decanol was then replaced by octanol and heptanol in additional experiments. Results indicated that the complex fluid multiphase behavior in ternary systems can be correlated with transformations between types of fluid phase behavior.

Electrochemical carbon

Article Abstract:

Electrochemical carbon is elemental carbon produced electrochemically from carbon compounds. Electrocarbonization can take place on electrodes in liquid electrolytes, by electrolysis of benzene and other amines, through reduction of CO2, and other processes. Electrochemical carbon is highly adsorbent, very reactive, readily oxidized at low temperature, and paramagnetic.
