Supercritical Fluid Chromatography

Science, 1983
Chromatographic separations with a supercritical fluid as the mobile phase were suggested more than 20 years ago. Availability of commercial hardware makes this technique more widely usable today. Many separations by this method are now carried out with supercritical carbon dioxide as the mobile phase and packed liquid-chromatography ...

Electrodeposition from supercritical fluids

Physical Chemistry Chemical Physics, 2014
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the

Crossover from gas-like to liquid-like molecular diffusion in a simple supercritical fluid [PDF]

Nature Communications
According to textbooks, no physical observable can be discerned allowing to distinguish a liquid from a gas beyond the critical point. Yet, several proposals have been put forward challenging this view and various transition boundaries between a gas-like

Production of solid fuels by hydrothermal treatment of wastes of biomass, plastic, and biomass/plastic mixtures: A review

Journal of Bioresources and Bioproducts, 2022
Traditional disposal methods of biomass and plastic waste, such as landfill, combustion, and compost, no longer meet the requirements of carbon reduction, carbon neutrality, and sustainable society due to low utilization efficiency and severe pollution ...

Advances in low-temperature extraction of natural resources using liquefied dimethyl ether

Resources Chemicals and Materials, 2022
This review summarized the valuable works on the extraction technologies using pure liquefied dimethyl ether (DME) as the organic solvent. DME is a colorless gas with a slight ether-like fragrance at room temperature and pressure.

Highly crystalline graphite-like carbon from wood via low-temperature catalytic graphitization

Carbon Trends, 2022
In this study, we investigated the synthesis of wood-sawdust-derived high-crystalline graphite-like carbon. The sawdust was first impregnated with Fe and semi-carbonized by a hydrothermal treatment (HT) at 250°C, followed by the second carbonization ...

A Study on Generation and Feasibility of Supercritical Multi-Thermal Fluid

Energies, 2022
Supercritical multi-thermal fluid is an emerging and efficient heat carrier for thermal recovery of heavy oil, but the generation of supercritical multi-thermal fluid and its feasibility in thermal recovery are rarely discussed. In this paper, generation

Electrochemistry in supercritical fluids [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte.
