Ion-Pair-Supercritical Fluid Extraction of Clenbuterol from Food Samples [PDF]
, 1995 Simultaneous ion-pair/supercritical fluid extraction (SFE) was investigated as an alternative to liquid solvent extraction for clenbuterol determination. Clenbuterol was extracted from diatomaceous earth and food matrices (feedstuff, lyophilized milk and

Modelling and experimental study of separators for co-solvent recovery in a supercritical extraction process [PDF]
, 2006 Co-solvent recovery in supercritical extraction is addressed here through a theoretical description of the behaviour of a CO2 + co-solvent mixture into a cascade of cyclonic separators, such as those existing in conventional fractionation processes based

Strategies for Supercritical Fluid Extraction of Polar and Ionic Compounds [PDF]
, 1996 The methods used to facilitate the supercritical fluid extraction (SFE) of polar and ionic compounds are based on two general principles, either increasing the polarity of the supercritical fluid (SF) (usually CO2) used as extractant or reducing the ...

Supercritical fluid extraction of phenol compounds from olive leaves [PDF]
, 1998 A clean, highly selective supercritical fluid extraction (SFE) method for the isolation of phenols from olive leaf samples was examined. Total phenol extracts were determined using the Folin-Ciocalteu reagent. Dried, ground, sieved olive leaf samples (30

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...
