Effect of solutes on the viscosity of supercritical solutions.
TL;DR: It is shown that solutes can impart significant structure to supercritical solutions, resulting in unexpectedly high solution viscosity at pressures close to the critical value, and a general model is presented for simple solutes whereby the viscosITY of a supercritical solution can be calculated from the molecular volume of the solute and the viscolysis of the pure fluid.

Developments in hydrogenation technology for fine-chemical and pharmaceutical applications.
TL;DR: Developments in chiral catalysis, methods to support and fix homogeneous catalysts, novel reactor and mixing technology, high-throughput screening, supercritical processing, spectroscopic and electrochemical online process monitoring, monolithic and structured catalysts and sonochemical activation methods illustrate the scope and breadth of evolving technology applied to hydrogenation.

Thermochemical Decomposition of Microcrystalline Cellulose Using Sub- and Supercritical Tetralin and Decalin with Fe3O4
TL;DR: In this article, a thermochemical liquefaction of microcrystalline cellulose was investigated in sub-and supercritical solvents in a batch reactor, and the results showed that tetralin was the most effective solvent with respect to the conversion at every tested condition starting from 350 °C.
Journal ArticleDOI
Foaming Behaviour and Compressive Properties of Microcellular Nanostructured Polystyrene
TL;DR: In this article, a batch foaming process has been employed to obtain microcellular materials from polystyrene plus a SBM copolymer (polystyrene-co-1,4-polybutadiene-copoly(methyl methacrylate).

Effect of Catalyst Properties on Hydrocracking of Pyrolytic Lignin to Liquid Fuel in Supercritical Ethanol
TL;DR: In this paper, the effects of the metal-acid bifunctional catalyst properties, including acidity, pore size and supported metal on hydrocracking of pyrolytic lignin in supercritical ethanol and hydrogen were investigated at 260 °C.

Reactions at supercritical conditions: Applications and fundamentals
TL;DR: A review of chemical reactions in and with supercritical fluids can be found in this paper, where the authors discuss both fundamental studies and applications of reactions at supercritical conditions, with focus on work published after 1985.
