Chemical diffusion of fluorine in jadeite melt at high pressure [PDF]
, 1984 The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 1400°C using diffusion couples of Jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion

The Effect of the Surroundings to the Apparent Diffusion Coefficient on Diffusion Weighted Imaging
Japanese Journal of Radiological Technology, 2010 Diffusion weighted imaging (DWI) is now widely used in magnetic resonance (MR) imaging of the head and body. Moreover, the Apparent diffusion coefficient (ADC) value is often used for the differential diagnosis of the tumor. However, the effect of the surroundings on the ADC value has not been reported.
