Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

The realities of storing carbon dioxide - A response to CO2 storage capacity issues raised by Ehlig-Economides & Economides [PDF]

, 2010
In a recent publication, Ehlig-Economides & Economides (2010) have sought to demonstrate that carbon dioxide capture and storage (CCS) is not technically or economically feasible, based on a supposed lack of underground storage capacity. We consider

Carbon Dioxide, a Solvent and Synthon for Green Chemistry [PDF]

, 2005
Carbon dioxide is a renewable resource of carbon when we consider the reuse of existing CO2 as a carbon source for producing chemicals. The development of new applications is of major interest from the point of view of carbon dioxide sequestration and ...

High-temperature corrosion resistance of nickel-base alloy 617 in supercritical carbon dioxide environment

Materials Research Express, 2020
Corrosion behavior of Inconel 617 in supercritical carbon dioxide at 650 °C and 15 MPa for 1000 h was investigated. X-ray diffraction, high-resolution transmission microscopy, and Raman spectrum were used to observe and analyze the corrosion products ...

Adsorption of Carbon Dioxide on Proteins in the Supercritical Region. [PDF]

Agricultural and Biological Chemistry, 1991
The adsorption isotherms for C02 on several proteins were measured over the wide range of pressures by the gravimetric method. The apparent amount of isothermal adsorption was a maximum at just above the critical pressure, and remained constant at higher pressures, the amount differing among casein, gelatin, gluten and ovalbumin.

Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

Drug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.
