Supercritical fluid processing applications in biomaterials

Supercritical Fluid Processing of Polymers

We have applied in situ FTIR, ATR-IR and photoacoustic spectroscopy to identify for the first time specific molecular interactions between CO2 and polymers that may be responsible for the plasticization of glassy polymers. The changes in IR spectra of CO2 incorporated into various polymers indicate a specific interaction between CO2 and polymer functional groups. Increased polymer segmental mob...

Supercritical fluid extraction: Recent advances and applications.

Among the different extraction techniques used at analytical and preparative scale, supercritical fluid extraction (SFE) is one of the most used. This review covers the most recent developments of SFE in different fields, such as food science, natural products, by-product recovery, pharmaceutical and environmental sciences, during the period 2007-2009. The revision is focused on the most recent...

Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

The use of supercritical fluid extraction technology in food processing

Applications of supercritical fluid extraction and chromatography in forensic science.

Supercritical fluid technology is a rapidly expanding analytical technique. Here we give a brief insight into the background of supercritical fluid technology and how supercritical fluid extraction and supercritical fluid chromatography work in analysis. The applications of these two techniques in forensic science are known to be important. The main area of forensic use of supercritical fluid t...
