Coupling Atomic Confinement With CO2 Pressure for Selective and Stable CO2 Electroreduction

Carbon Energy, EarlyView.
The coupling of high‐pressure operation with atomic‐scale catalyst design was investigated via an electrochemical cation implantation (ECI) process to create confined reaction environments over SnOx catalyst. The synergistic interplay between structural confinement and CO2 pressure was investigated, and the reaction mechanism for CO2RR to CO was ...

Influence of supercritical CO2 on the physical property of tight sandstone

Petroleum
In low-pressure gas reservoirs, water-based fracture fluid is difficult to flowback, which is unfavorable for several tight sandstone gas reservoirs in the Sichuan Basin with low pressure and high permeability geological characteristics.

Effects of dissolved oxygen and temperature on the stress corrosion of 06Cr17Ni12Mo2Ti stainless steel in supercritical water

工程科学学报, 2015
The effects of dissolved oxygen(DO) and temperature on the stress corrosion cracking(SCC) of 06Cr17Ni12Mo2 Ti stainless steel(SS) in supercritical water environments were investigated by slow strain rate tensile tests(SSRT).

Sequential Pressurized Liquid Extraction of Food Matrices: Fractionation, Selectivity, and Scale‐Up

ChemFoodChem, EarlyView.
Sequential pressurized liquid extraction separates food‐processing side streams into chemically distinct fractions by changing solvent polarity and operating conditions across stages. Lipophilic and phenolic compounds are recovered selectively, while co‐extraction is reduced.

Hydrothermal Gasification Performance of Iranian Rice Straw in Supercritical Water Media for Hydrogen-Rich Gas Production

BioResources, 2016
As a clean and green alternative fuel to replace fossil fuels, hydrogen could be an ideal fuel for the future. Supercritical water gasification of lignocellulosic agricultural residues results in H2 production with zero CO2 emission, which makes this ...

Dilemma in Carotenoids Versus Polyhydroxyalkanoates (PHAs) Synthesis Using Haloarchaea as Cell Factories

Chemistry – A European Journal, EarlyView.
Production of PHAs by haloarchaea: the production of carotenoids and PHAs is concomitant, and consequently, various metabolic pathways compete for the carbon source. This results in a loss of PHA production efficiency. Efficient control of carbon source utilization (favoring certain metabolic pathways at the expense of others) is the key to the ...
