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 ...
Objective To investigate the diffusion coefficient of water molecules using magnetic resonance(MR)diffusion weighted spectroscopy(DWS)with normal medical magnetic resonance device.Methods Two powerful diffusion gradient magnetic fields were applied before the second and after the third π/2 radio frequency ...
From our calculations we show that, at low temperatures, the diffusion of molecules in the bulk of a LDA ice is driven by the self-diffusion of water molecules in the ice. With this study we demonstrate that molecular dynamics allows the calculation of diffusion coefficients for small molecules...
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 ...
The transport of water in nanoconfined geometries is different from bulk phase and has tremendous implications in nanotechnology and biotechnology. Here molecular dynamics is used to compute the self-diffusion coefficient D of water within nanopores, aro
In the present work, time-resolved attenuated total reflection Fourier transform infrared spectroscopy (ATR-IR), near-infrared (NIR) spectroscopy, and generalized two-dimensional (2D) correlation analysis were used to investigate water diffusion processes and the state of water molecules in six differen...
Define water diffusion. water diffusion synonyms, water diffusion pronunciation, water diffusion translation, English dictionary definition of water diffusion. diffusion In the process of diffusion of a single solute, a concentration of molecules on one
A small fan was also placed inside the container to promote faster diffusion of the water molecules in the air. This setup allowed the variation of internal humidity in varying rates, depending on the fan speed. The humidity chamber allowed for the insertion of two LPFGs at once, one with ...
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 ...
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...
