Supercritical carbon dioxide (S-CO2) has the advantages of amphoteric liquid and gas, which possesses many unique characteristics, such as good compressibility, high density, solubility, fluidity low viscosity. The Brayton cycle with S-CO2 is considered to have promising applications, especially for power conversion industries. However, corrosion degradation structural materials hinder developm...

CO2 capture and further conversion into valuable products can be a promising solution against global warming. Normally, CO2 conversion can be achieved by chemical methods, by photocatalytic and electrocatalytic reduction [1]. Specifically for electrocatalytic reduction of CO2, challenges remain, such as the slow kinetics of CO2 electro-reduction, even when high electrode reduction potential are...

Thermodynamic phase equilibrium data, which are relevant to the development of a novel production process for polycarbonates from CO2 and epoxides, are presented. In this solventfree process, CO2 is coupled to epoxides using various transition-metal catalyst systems. Data on the performance of these systems are discussed. Additionally, the polycarbonate solubility in CO2 and CHO is considered, ...

We report in this paper novel chemistry that addresses the problem of surfactant solubility in supercritical CO2 for metal nanoparticle synthesis. This new approach for the preparation of organic-functionalized inorganic nanoparticles relies on the reduction of a metal precursor in a CO2-containing insoluble polymer. Reduction of the metal with H2 leads to small nanocrystals stabilized by the p...

The effects of sevoflurane or isoflurane on arterial blood gas, arterial oxyhaemoglobin saturation and end-tidal CO2 tension were monitored during induction and maintenance of anaesthesia in 10 premedicated New Zealand White (NZW) rabbits.For induction, the anaesthetic agents were delivered via a face-mask. After induction was completed, an endotracheal tube was introduced for maintenance of an...

MRST-co2lab is a collection of open-source computational tools for modeling large-scale and long-time migration of CO2 in conductive aquifers, combining ideas from basin modeling, computational geometry, hydrology, and reservoir simulation. Herein, we employ the methods of MRST-co2lab to study long-term CO2 storage on the scale of hundreds of megatonnes. We consider public data sets of two aqui...

Integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical CO2 as a nonsolvent for the polymer solution. In present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. It is shown that the presence of silica nanoparticles not only di...

Ionic liquids (ILs) are proposed as potential “green” solvents with remarkable properties. Deep eutectic (DESs) a new type of ILs additional properties, such higher biodegradability and lower price. DESs absorbents for various gas separations, CO2/N2, CO2/H2/CO, H2S/CH4, N2O/N2. Due to their large number, the screening is crucial. Although high absorption capacities were screened using solubili...

New composite membranes based on porous anodic alumina films and polymer of intrinsic microporosity (PIM-1) have been prepared using a spin-coating technique. According to scanning electron microscopy, partial penetration of polymer into the pores of alumina supports takes place giving rise to selective polymeric layers with fiber-like microstructure. Geometric confinement of rigid PIM-1 in the...
