Reverse micelles in supercritical carbon dioxide for pharmacological applications: a spectroscopic characterization
The aim of this research is to characterize microemulsions in supercritical (sc) CO2 using two spectroscopic techniques (UV-Vis and FT-IR) and apply the microemulsion approach to extract impurities from a pharmacological ...
Synthesis and characterization of Sulfonated Poly(Styrene-Isoprene-Styrene): Effects of linear vs branched morphology and counter-ion substitution
This investigation studied the resulting nanostructure of ionic membranes composed of sulfonated copolymers with thermoplastic and elastomeric blocks. Linear poly(styrene-isoprenestyrene) (L-SIS) and branched poly(styren ...
Perfluorinated and sulfonated proton exchange membranes: Effect of supercritical fluid processing on ion exchange capacity and proton conductivity
The present work has processed Nafion® and sulfonated polystyrene-isobutylenestyrene (SIBS) with supercritical fluid (SCF) carbon dioxide at a 40°C and 200 bar with the aid of ten co-solvents of different size and polarity. ...
Solubilities of anti-cancer and anti-AIDS drugs in supercritical carbon dioxide
Solubility data for pharmacological drugs in supercritical fluids (SCFs) is of great importance, because there is an environmental and cost effective need for alternative specialty separation methods. This research was ...
Supercritical fluid processing of sulfonated styrenic tri-block polymers
The increasing need to replace current materials with new or reprocessed ones that have more specific properties and uses has led to the use of supercritical fluids (SCFs) for polymer reprocessing. Kraton® poly ...
Supercritical fluid processing of perfluorinated and sulfonated membranes
Over the past years, one of the most important challenges facing industry has been the search for environmentally benign and cost effective alternatives to traditional power sources. Many industries invest considerable ...
