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 ...

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. ...

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 ...

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 ...

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 ...
