A picture of a biological membrane that includes compositional and phase heterogeneity is consistent with many observations on cells. Simons and van Meer pointed this out to explain the sorting of ...

It has become increasingly important for chemists and analysts to be able to test and determine the various components that may be present in mixtures, both qualitatively and quantitatively, to solve ...

As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out.

The very first life on earth is thought to have developed from 'protocells' -- liquid mixtures of many different types of molecules. Researchers have now shown that in such mixtures, small imbalances ...
