Author:Labuschagne, Philip W; Naicker, B; Kalombo, LonjiDate:Feb 2016The purpose of this investigation was to determine whether shellac, a naturally occurring material with enteric properties, could be processed in supercritical CO2 (sc-CO2) using the particles from gas saturated solution (PGSS) process and ...Read more
Author:Labuschagne, Philip WDate:Oct 2010The use of supercritical CO2 as medium in polymer processing eliminates many of disadvantages associated with other means of processing, i.e. high temperatures or toxic solvents. The “soft” processing conditions make CO2 specifically suitable ...Read more
Author:Labuschagne, Philip WDate:01 Sep 2010Supercritical Carbon-dioxide (CO2) is fast becoming an important commercial and industrial solvent of choice, largely due to its solvating efficiency and low environmental impact. In many instances, supercritical CO2 can replace the use of ...Read more
