Die Fraktionierung von Polymethylmethacrylaten nach dem Molekulargewicht durch Gegenstromverteilung
A polydisperse sample of polymethylmethacrylate with an average molecular weight of 168000 has been fractionated by countercurrent distribution into fractions of different molecular weight using a phase pair prepared from acetone, n-hexane and water.

Kinetic modeling of countercurrent saccharification
Background Countercurrent saccharification is a promising way to minimize enzyme loading while obtaining high conversions and product concentrations. However, in countercurrent saccharification experiments, 3–4 months are usually required to acquire a ...

Purification and characterization of phthalanilide-lipid complexes from tissues
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

Dispersed Mobile-Phase Countercurrent Chromatography
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.

Countercurrent distribution of inositol lipids of plant seeds
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

Imaging spontaneous imbibition in full Darcy‐scale samples at pore‐scale resolution by fast X‐ray tomography [PDF]
Spontaneous imbibition is a process occurring in a porous medium which describes wetting phase replacing nonwetting phase spontaneously due to capillary forces.
