The journal "Advanced Materials" is celebrating its 20th anniversary. Having an Impact Factor of 8.191 Advanced Materials is one of the most influential journals in the field.
Therefore a quick review of articles published in this journal related with "supercritical fluids" may give us an idea of the its use in materials design. From 1993 to 2008, 43 articles talk about something related to supercritical fluids.
Last trend is the use of SCF in the synthesis of Nano-tubes, which is at the same time one of the more promising lines of research in materials. For example in the next number of the journal an article entitled "Synthesis of Carbon-Nanotube Composites Using Supercritical Fluids and Their Potential Applications" will be published.
