    1. Processing of Lovage into High-Value Components Using Supercritical CO2 and Pressurized Liquid Extraction

      High-pressure techniques, namely supercritical CO2 and pressurized liquid extraction, demonstrate the potential to significantly increase the efficiency of processing of different anatomical parts of lovage into high-value fractions based on their solubility in nonpolar (CO2) and protonic (methanol/water) solvents under supercritical and subcritical conditions.

    1. Sterilization of Medical Products from Collagen by Means of Supercritical CO2

      Volker Herdegen, Alexander Felix, Roland Haseneder, Jens-Uwe Repke, Kathrin Leppchen-Fröhlich, Ina Prade and Michael Meyer

      Article first published online: 6 JUN 2014 | DOI: 10.1002/ceat.201300679

      Due to its favorable properties, collagen is increasingly used in medical devices. Nowadays, the necessary sterilization of this sensitive material may be conducted only by ethylenoxide and γ irradiation. To overcome the drawbacks connected to those methods, a new sterilization procedure using supercritical CO2 and the addition of small amounts of sterilization aid is successfully tested.

    1. Simulating Supercritical Water Jets with a Variable Turbulent Prandtl Number

      Martin J. Schuler, Tobias Rothenfluh, Panagiotis Stathopoulos, Dragana Brkic, Thierry Meier and Philipp Rudolf von Rohr

      Article first published online: 8 MAY 2014 | DOI: 10.1002/ceat.201300661

      Thumbnail image of graphical abstract

      Due to the strongly varying fluid properties of water around the pseudo-critical point, difficulties in simulating the thermal field of submerged supercritical water jets were detected. A locally varying turbulent Prandtl number was implemented to significantly improve numerical predictions with respect to axial temperature measurements
