Spin-Exchange Term in the Solvent Equation of State Near the Critical Point for Electron Transfer Reactions [PDF]

open access: yes, 2000
Phenomenological Equations of State (EOS) for fluids near their critical point have been obtained using literature compression factor data, Zc = Pc Vc/(n R Tc) = 0.40 to 0.10 in Table I (Pc, Vc/n, Tc are the pressure, volume per n mole, and the absolute ...

Studie tepelného oběhu s nadkritickým CO2 [PDF]

open access: yes, 2018
With the increasing interest in solar and geothermal power plants as well as waste heat recovery systems from many technologies, the whole world is more focused on the gas power cycles. Especially, the supercritical carbon dioxide (S-CO2) cycles are very

Nitrogen sorption as a tool for the characterisation of polysaccharide aerogels [PDF]

open access: yes, 2011
Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, k- carrageenan, and agar) have been characterised by physisorption ofN2. Surface areas as high as 570m2 g−1 have been measured.

Oxidation of cellulose in pressurized carbon dioxide [PDF]

open access: yes, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Structure of oleogels from κ-carrageenan templates as affected by supercritical-CO2-drying, freeze-drying and lettuce-filler addition

open access: yesFood Hydrocolloids, 2019
Templates intended for food-grade oleogel production were produced by supercritical-CO2-drying and freeze-drying of κ-carrageenan hydrogels (0.4 g/100 g). Supercritical-CO2-drying produced hard (61 N firmness) and shrunk oleogels, which presented 80% oil

Supercritical CO2 Effects on Calcite Wettability: A Molecular Perspective

open access: yesJournal of Physical Chemistry C, 2020
The wettability behavior of reservoir rocks plays a vital role in determining CO2 storage capacity and containment security. Several experimental studies characterized the wettability of CO2/brine/rock systems for a wide range of realistic conditions. To

Dimensionless scaling of heat-release-induced planar shock waves in near-critical CO2

open access: yes, 2017
We performed highly resolved one-dimensional fully compressible Navier-Stokes simulations of heat-release-induced compression waves in near-critical CO2. The computational setup, inspired by the experimental setup of Miura et al., Phys. Rev.
