Study of the diffusion of water molecules in dilute solutions of dextran using the PMR pulse method - ScienceDirectThe PMR pulse method was used to determine diffusion coefficients of water in dextran solutions of a molecular weight ranging between 18·5×10 3 and 5×10 5 . In the ...

When the diffusion of water in both directions is equal, the system is in equilibrium. If hydrostatic pressure is initially applied to the sugar solution, the intake of water through the membrane can be reduced. The hydrostatic pressure necessary to prevent equalization of the concentration by diff...
The diffusion of water molecules bound to PE and PG in the PE-PG bilayer is slower than those bound to PC in the PC bilayer [137]. The analysis of water lateral self-diffusion in a bilayer interfacial region that includes the effect of confinement, demonstrates that the effect of the ...
c, A comparison of the water-edited 13C CP NMR spectrum of induced (L11) poplar with a diffusion time of 4 ms (red) and the normal CP spectrum (blue) normalized to the cellulose C4 at 89 ppm. The increased relative intensity of the callose peaks shows that it is close to water...

Spectra of proton and deuteron magnetic resonance of water molecules in oriented biopolymer samples (collagen, DNA, cellulose) are interpreted on the basis of a model of molecular Schottki-type diffusion. The presence of narrow splittings are shown to be the result of slight distortions of ideal...

put on the rate of sorption of cell walls themselves. In order to investigate this and separate sorption from diffusion of water vapour, very thin wood samples must be used which was done in a range of sorption experiments by Christensen (1959,1965,1967), Christensen and Kelsey (1959) and ...
It shows that the diffusion ability of water molecules in insulating oil containing nanoparticles is weaker, which proves that the addition of nanoparticles can effectively restrain the diffusion of water molecules in oil. In addition, increasing the water concentration in the oil raises the diffusion...
