#42 - Materials Synthesis and Processing with Compressed or Supercritical Fluids I: General (01F03)
This session invites contributions that relate to the use of gas expanded liquids, near-critical, or supercritical fluids to produce materials with new or enhanced properties. This includes, but is not limited to, papers on formation of particles, films, coatings, and composite materials, using techniques such as rapid expansion, anti-solvent precipitation, fluidization, and dispersion and impregnation using supercritical fluids. Papers are encouraged that describe developments in experimental technique, developments in process characterization and instrumentation technologies, and advances in theoretical modeling and understanding of the processes.
