196 SUPERCRITICAL FLUIDS
Supercritical fluids are involved in a wide variety of applications which have shown a significant progress in recent years. Many industrial sectors are concerned including cosmetics, pharmaceutics, materials, chemistry or energy. Other areas are in rapid development such as the cleaning of mechanical parts or the surface preparation of microelectronics. It should be noted that water (Tc = 374 °C, Pc = 221 bars), which critical point is higher than that of CO2 (Tc = 31 °C, Pc = 74 bars), is nevertheless very much studied as a reaction medium, finding applications in the synthesis of nanoparticles and the recovery and treatment of waste.

23 Making adhesives surfaces reversible
Thermo-expandable microspheres (TEMs), which consist of an outer shell of copolymer thermoplastic resin encapsulating a liquid hydrocarbon, when the heat trigger is applied at command the microspheres expand to over 100 times their volume, acting as a pressure activator to cleanly break the bond at the interface, and the cohesive structure. A key part of the patented technology is the functionalization of the TEMs surfaces, e.i. a conducting material is applied onto the polymeric shells of the microspheres. This additional layer enables quicker ways to get the heat to the TEM surface without damaging the material itself.

14 Supercritical water process for total degradation of organic molecules
Around its critical point at 221 bars and 375°C, water is a highly oxidizing medium. Oxidation of any organic molecules undergo in a very fast chemical reaction with oxygen species from the critical water. The residues of the reaction are mainly carbon dioxide, water, nitrogen and sulphates and phosphates.The water at the output of the process does not contain any more organic molecule.

6 Process for industrial production of nanoparticles using supercritical water process
The use of hydrothermal conditions allows the very fast synthesis of high added value nanoparticles from an aqueous solution of metallic salts. This technology has proven being very versatile versus composition, synthesizing very high quality NP at both lab and pilot scale, with high reproducibility.The process includes a wall-free mixing technology which brings stability of the reaction volume and allows a fully continuous operation of the production line.

5 New method of encapsulation
Metal oxide micelles modified with organic ligands on the surface have been prepared. The ligands applied in sol-gel synthesis of inorganic materials are hydrophobic ones such as carboxylate or phosphonate groups. Positively charged micelles are attracted to the negatively charged cell membrane surface, are discharged and coalesce to form a continuous shell. This unique bioencapsulation method covers also the approaches for chemically or biochemically controlled release of the bioactive components, tissues or organisms from said particles.
