This is a dedicated high power gradient diffusion probe that are the ultimate tools to deliver resolution in DOSY and in q-space experiments. High gradient strength and fast switching times enable ...

This diffusion was also quantified by measuring ... There is thus ample evidence that regulatory gene expression gradients are present in certain regions, and that these gradients play a role ...

This is due to the random movement of the molecules. The direction of diffusion is said to be 'down' or 'with' the concentration gradient. Diffusion stops when the concentration of the substance ...

Diffusion from electrical potential gradients, thermal gradients, and capillarity effects; The Diffusion equation; Methods of solution to diffusion equation; Diffusion in multicomponent solids; ...

Diffusion Substances move from a high to a lower concentration down a concentration gradient Carbon dioxide, oxygen, water, food substances, wastes, eg urea No Osmosis Water moves from a high to a ...

The two solutes plus the solvent can be clearly resolved. Diffusion ordered spectroscopy creates a two-dimensional plot by acquiring a set of spectra as a function of the amplitude of the gradient.

As with any diffusion theory, there must be a gradient in the distribution of particles, and some mechanism by which the particles are scattered. But in the magnetosphere collisions between ...
