Supercritical CO2 as a refrigerant

open access: yes
The present deliverable documents the achievement of Task 10.4 towards a universal adoption of natural refrigerants for future generations of detectors, covering in particular situations where water or boiling CO2 flows cannot be used. The programme announced in the submitted proposal has been extended thanks to synergies with internal funds to the ...

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

open access: yesChemFoodChem, 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.
