Matter transport is controlled by diffusion through the binder phase.
In this system, oxygen is added by diffusion through a silicone membrane tube.
Cartilage cells, called chondrocytes, occur at scattered sites through the cartilage and receive nutrition by diffusion through the gel; cartilage contains no blood vessels or nerves, unlike bone.
Further, it was observed that polyelectrolyte nanoparticles released the drug by diffusion through the matrix following Higuchi's square-root kinetics.
Transfer from IFABP occurs during protein membrane collisional interactions, while for LFABP transfer occurs by diffusion through the aqueous phase.
EuIII-EDTA was not quantitatively dissociated by diffusion through the rock.
Although nonpolar chemicals cross the skin by diffusion through the stratum corneum, no active transport exists in the dead cells of this layer.
He also showed that if decompression were effected sufficiently slowly, the excess of air which had been taken up could escape by diffusion through the lungs, and thus bubbling and symptoms could be avoided.
Transport of water occurs by diffusion through film-flow resulting in film-expansion along water-wet grains.
According to this model, the copper solubilization was controlled by diffusion through a product layer (mainly jarosite), while zinc dissolution did not show a defined control step.
Neuroactive substances are released from astrocytes through several distinct molecular mechanisms, for example, by diffusion through membrane channels, by translocation via plasmalemmal transporters or by vesicular exocytosis.
