These results show the importance of film formation on problems caused by water diffusion such as surfactant leaching.
So, water diffusion into the PLGA matrices containing HA becomes increasingly difficult, thereby reducing the degradation rate.

These authors explained that the large concentration differences between the osmotic solution and watermelon increase the solute and water diffusion rates.
A novel MRI tracer-based method for measuring water diffusion in the extracellular space of the rat brain.
The determination of the water diffusion coefficient through the pith of Raffia vinifera is done by using Fick's dual stage law.
Unlike Brownian motion in a fluid, the freedom of water diffusion in tissues depends heavily on its interactions with the adjacent components, such as tissue type/arrangement, macromolecules, collagen fibers, cellular density, and the integrity of the cellular membranes.
To actually create the brain "fingerprint," the researchers took the data from the diffusion MRI then reconstructed it to calculate the distribution of water diffusion along the fibers of the white matter (the inner parts of the brain).
(6) Subsequently, the extracellular space becomes enlarged as the number of oligodendroglia and neuronal axons decrease, causing increased water diffusion and giving rise to high DWI signal without low ADC signal.
[4, 7 ADC is a quantitative parameter calculated from DWI that combines the effects of capillary perfusion and water diffusion. [8] ADC value is calculated for each pixel of the image and is displayed as a parametric map.
