Studies into solid core drug delivery system using haemoglobin as a model drug and supercritical fluid processing for encapsulation
… as core material, haemoglobin as model drug and supercritical fluid processing as encapsulation technique. Silica particles of different morphology were used as a carrier material for protein immobilisation and fatty acids coating was performed using supercritical carbon dioxide (CO2) as a …

Preparation and investigation of polymer-foam films and polymer-layer systems for ferroelectrets
… solid films without any pollution or impurity. Supercritical carbon dioxide (CO2) or nitrogen (N2) are usually employed as foaming agents due to their good solubility in several polymers. Polyethylene propylene (PEN) is a polyester with slightly better properties than PET. A “voiding + inflation …

Phase Behavior and Phase Separation Kinetics in Polymer Solutions under High Pressure
… in polymer solutions in binary mixtures of supercritical carbon dioxide (CO2) and organic solvents were studied for two systems. Solutions of polyethylene (PE) in CO2 + n-pentane were selected as one model system to study both the solid-fluid (S-F) and liquid-liquid (L-L) phase transitions …

An experimental study of supercritical CO2 flow in pipes and porous micro-models for carbon sequestration applications
The flow of high-pressure, near-critical CO2 in configurations relevant to CO2 sequestration was investigated. The first configuration was CO2 flow in pipes and orifices at pressures and temperatures close to the critical point of CO2 (74 bar, 31°C). A 60-cm-long stainless steel pipe with 2.1 mm …
