Nanocatalysts deposition assisted by supercritical carbon dioxide technology: A review

Self-Assembled Monolayers deposition in Supercritical Carbon Dioxide

Self-Assembled Monolayers of organic molecules have been successfully deposited onto wafer surface in supercritical carbon dioxide. Deposition method and apparatus are described. The layers are characterized by AFM and water droplet contact angle. Interest of this technique compared to liquid and vapor phase is discussed and studied for surface conversion from hydrophilic to hydrophobic for dif...

Deposition of yttrium oxide thin films in supercritical carbon dioxide

A synthetic avenue for the formation of yttrium oxide thin films on Si native oxide surfaces is demonstrated by the reaction of Tris(2,2,6,6tetramethyl-3,5-heptanedionato) yttrium(III) with inorganic (H2O2) and organic (tert-butyl and di-tert-amyl) peroxides in supercritical carbon dioxide. The reactions are carried out in a hot wall reactor at temperatures below 130 °C and pressures ranging fr...

Antifungal Textiles Formed Using Silver Deposition in Supercritical Carbon Dioxide

The antifungal properties of two silver-coated natural cotton fiber structures prepared using a supercritical carbon dioxide (scCO2) solvent were examined. Scanning electron microscopy confirmed that the scCO2 process may be used to produce cotton fiber textiles with uniform silver nanoparticle coatings. A version of the Kirby-Bauer disk diffusion test was used to assess the ability of these te...

Solubility of organometallic complexes in supercritical carbon dioxide: A review

The solubility and solubility trends of organometallic complexes in supercritical carbon dioxide are reviewed. The influence of intermolecular forces, physical properties and the metal chelates on solubility is explored. A number of thermodynamic models used to predict the solubility behavior of organometallic complexes in supercritical carbon dioxide, and the advantages and limitations to thes...
