Dispersed Mobile-Phase Countercurrent Chromatography

open access: yesSeparations, 2016
Countercurrent distribution based on liquid–liquid partition is a powerful separation method with minimal incurrence of loss of solutes, but its industrial application has been limited by cumbersome shifting of immiscible solvents.

Ecomorphological and Age-Related Adaptations in the Tongues of Phocoena dioptrica (Spectacled Porpoise) and Phocoena spinipinnis (Burmeister’s Porpoise) (Phocoenidae: Cetacea) [PDF]

open access: yesAnimals
Vertebrates’ tongues reflect part of their adaptations to diverse feeding strategies, the types of food items they eat, and the environments where they live.

Countercurrent distribution of soybean fatty acid methyl esters biosynthetically labeled with H3 and C14

open access: yesJournal of Lipid Research, 1961
Fatty acids randomly labeled with C14 and with H3 were prepared by culturing soybean plants (a) in the presence of C14O2, and (b) with H3OH in the nutrient medium.

Investigation on the Performance of CO2 Absorption in Ceramic Hollow-Fiber Gas/Liquid Membrane Contactors

open access: yesMembranes, 2023
The absorption efficiencies of CO2 in ceramic hollow-fiber membrane contactors using monoethanolamine (MEA) absorbent under both cocurrent- and countercurrent-flow operations were investigated theoretically and experimentally; various MEA absorbent flow ...

Purification and characterization of phthalanilide-lipid complexes from tissues

open access: yesJournal of Lipid Research, 1966
What appears to be a new class of phospholipids has been isolated from dog brain in the form of complexes with a substituted phthalanilide. The complexes were extracted by chloroform-methanol and purified by countercurrent distribution in solvent systems

Effectiveness of a salt transport cascade in the renal medulla: computer simulations [PDF]

open access: yes, 1987
Based on morphological observations, it has been concluded that the upper parts of the long descending limbs of Henle's loops should be able to secrete salts into the tubular fluid (Kriz, W. Federation Proc. 42:2379-2385, 1983).

Countercurrent distribution of inositol lipids of plant seeds

open access: yesJournal of Lipid Research, 1969
The inositol lipids of plant seeds consist of phosphatidyl inositol, the phytoglycolipids, and a previously uncharacterized ceramide-phosphate-polysaccharide. These three species have been separated from each other and from the common glycerophosphatides

Die Trennung von Carotinoidgemischen durch Gegenstromextraktion (II)

open access: yesCHIMIA, 1973
Countercurrent distribution has been used for the separation of β-carotene and its epoxides without rearrangement reactions. The separation of an extract from Carica papaya shows that this method is suitable for the detection of carotenoids which occur ...

Analytical, Preparative, and Industrial-Scale Separation of Substances by Methods of Countercurrent Liquid-Liquid Chromatography

open access: yesMolecules, 2020
Countercurrent liquid-liquid chromatographic techniques (CCC), similar to solvent extraction, are based on the different distribution of compounds between two immiscible liquids and have been most widely used in natural product separations.

Observations of the California Countercurrent [PDF]

open access: yes, 1984
Results from moored current meters, 150 - 350 m, are discussed for a region over the continental slope off Cape San Martin, California from January 1979 to April 1980.
