Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]
, 2012 In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

Rhombohedral calcite precipitation from CO2-H2O-Ca(OH)2 slurry under supercritical and gas CO2 media [PDF]
Journal of Crystal Growth 308 (2007) 228-236, 2008 The formation of solid calcium carbonate (CaCO3) from aqueous solutions or slurries containing calcium and carbon dioxide (CO2) is a complex process of considerable importance in the ecological, geochemical and biological areas. Moreover, the demand for powdered CaCO3 has increased considerably recently in various fields of industry.

The Development of a Chemical Kinetic Mechanism for Combustion in Supercritical Carbon Dioxide [PDF]
arXiv, 2022 Direct fired supercritical CO2 (sCO2) power cycles allow for the combustion of gaseous fuels under oxyfuel conditions with inherent carbon capture. As the CO2 is captured intrinsically, the efficiency penalty of capture on the overall plant is small, meaning that power plants achieve a similar efficiency to traditional fossil fuel power plants without ...

Linear instability of Poiseuille flows with highly non-ideal fluids [PDF]
J. Fluid Mech. 859 (2019) 89-125, 2018 The objective of this work is to investigate linear modal and algebraic instability in Poiseuille flows with fluids close to their vapour-liquid critical point. Close to this critical point, the ideal gas assumption does not hold and large non-ideal fluid behaviours occur.
