Selected papers from the 9th International Symposium on Supercritical Fluids (ISSF 2009) have been recently published in "The Journal or Supercritical fluids"
Whit the title "New Trends in Supercritical Fluids: Energy, Materials, Processing" the congress was held in Arcachon, France, May 18-20, 2009
The journal has been edited by Jacques Fages, Cyril Aymonier, François Cansell, Jacques Mercadier and Erdogan Kiran
You can find the abstracts and the access to the full text in ScienceDirect web page.

Mazda injection molding process uses supercritical fluids
Mazda Motor Corp. (Hiroshima, Japan) announced on Sept. 9 2008 that it has developed a new plastic injection molding technology with supercritical fluid technologies that enables a substantial reduction in the weight of plastic parts used in vehicles.
This molding technique cuts the consumption of plastic resins that are used as raw material by approximately 20 to 30 percent, with associated reductions in vehicle weight.

Recycling radioactive waste no longer a problem
Published in August 22nd, 2008 by IANS in http://www.thaindian.com/newsportal/
A new plant will help recover uranium from the ashes of radioactive wastes, which can then be recycled with an efficient, eco-friendly technology inspired by decaffeinated coffee and using supercritical fluids. The technique’s future may even hold the key to recycling the most dangerous forms of radioactive waste in the near future.

Supercritical Fluids Chromatography
The Supercritical Fluids Chromatography (SFC) is a kind of chromatography where the mobile phase is a supercritical fluid.
The most used SCF is the carbon dioxide (do not mix-up SCF SuperCritical Fluid and SFC Supercritical Fluid Chromatography).
Then SFC is a normal phase chromatography between the gas chromatography (GC) and the liquid chromatography (HPLC).
The systems are close to an HPLC but with a backpressure regulator to maintain the pressure above the critical pressure.
The stationary phase is in packed columns that can contain differents polar phases .
