The free-water method eliminates partial volume with water molecules that are free to diffuse in the extracellular space, providing better estimates of diffusivities within the tissue [ 41].
As can be seen in the mechanism shown in Figure 7, these excited states, i.e., (Ti3+-O−)*, contain the photogenerated electron and hole which are more localized on neighboring atoms [19, 20] and are closer than in bulk semiconductors, in which the charge carriers are free to diffuse.
2. The messenger proteins are free to diffuse [2] in the cytoplasm between the cell membrane and the nuclear membrane.
FRAP data can be characterized by two parameters, an apparent diffusion coefficient (D) which provides a measure of the mean squared displacement of the diffusing molecule per unit time, and a mobile fraction (Mf) a measure of the fraction of molecules that are free to diffuse over the time course of the experiment [37].
All of the spine cytosol species are free to diffuse through the spine neck into the adjacent dendrite.
Both small particles and soluble hydrocolloids are free to diffuse from the lumen but have the potential to be trapped by the intestinal mucus layer.
These metabolites were free to diffuse in the cell and the cell membrane was permeable to allow diffusion of these metabolites between the cell and external solution.
This latter non-aggregating fragment is free to diffuse within the ECM and is rapidly lost into the synovial fluid.
The wellbore pressure is free to diffuse into the surrounding formation when there is no mudcake on the wellbore wall (Figs. 2, 6).
After release, Syto 9 is free to diffuse into the core where its fluorescence increases upon binding DNA and RNA.
