Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The present study aimed to valorize broccoli by‐products (leaves and stems) through the extraction of bioactive compounds using supercritical fluid extraction (SFE). The influence of broccoli variety, plant part and maturation stage on total phenolic content (TPC), antioxidant activity and antimicrobial properties was evaluated ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Nested subcritical flows within supercritical systems [PDF]
In supercritical systems the design inlet and outlet pressures are maintained above the thermaodynamic critical pressure P sub C. Designers rely on this simple rule of thumb to circumvent problems associated with a subcritical pressure regime nested ...
