CO2-foam injection is a promising technology for reducing gas mobility and increasing trapping within the swept region in deep brine aquifers. In this work, consistent thermodynamic model based on combination of Peng-Robinson equation state (PR EOS) components with an activity aqueous phase implemented to accurately describe complex phase-behavior CO2-brine system. The module combined represent...

The interaction of a CO2 laser pulse with Sn-based plasma for a 13.5-nm extreme ultraviolet (EUV) lithography source was investigated. It was noted that a CO2 laser with wavelength of 10.6 μm is more sensitive to surface impurities as compared with a Nd:YAG laser with wavelength of 1.06 μm. This reveals that a CO2 laser is more likely absorbed in a thinner layer near the target surface. Compare...

open-celled foams are capable to allow the passage of fluids through their structure, because of interconnections between the open cells or bubbles and therefore these structures can be used as a membrane and filter. in thiswork, we have studied the production of polystyrene open-celled microcellular foam by using co2 as blowing agent. to achieve such structures, it is necessary to control the ...

Subterranean termites, Reticulitermes spp., were attracted to carbon dioxide (CO2) in laboratory and field tests. In behavioral bioassays, Reticulitermes flavipes (Kollar), Reticulitermes tibialis Banks, and Reticulitermes virginicus Banks were attracted to CO2 concentrations between 5 and 50 mmol/mol. In further bioassays, R. tibialis and R. virginicus were attracted to the headspace from poly...

Core-shell nanoparticles consisting of silica as core and surface-grafted poly(dimethylsiloxane) (PDMS) as shell with different diameters were prepared and used as heterogeneous nucleation agents to obtain CO2-blown poly(methyl methacrylate) (PMMA) nanocomposite foams. PDMS was selected as the shell material as it possesses a low surface energy and high CO2-philicity. The successful synthesis o...
