Determination of solid diffusion coefficient of lithium ion in LiCoO_2 by capacity intermittent titration technique;

Determination of solid diffusion coefficient of insertion-host electrode materials based on capacity parameter;

2) hydrogen storage alloy were respectively prepared by solid-state diffusion method and the two-stages method,which includes solid-state diffusion and subsequent ball milling.

Thus,it is provedthat the selective dissolution of zinc in brass is controlled by a solid-state diffusion process.

Polysilicon doped heavily is introduced as solid phase diffusion source to realize ultra shallow source and drain extensions.

Because of the complex structure of liquids and the complexity of diffusion process, the research is far from maturity, there has not been a rigorous theoretical equation for the prediction of liquid diffusion coefficients.

Using this interferometer,the distinct real-time interference fringes indicating the concentration profiles of the liquid were obtained,the liquid diffusion coefficient was simply and directly measured from the interferograms by finite fringe system intentionally in.

Due to imperfection of the theoretic prediction and empirical evaluation on liquid diffusion coefficients,the experimental methods have been got more attention from the researchers in this field.

From the model:① an equation which can be used to correlate liquid self - diffusivity under high pressure was obtained,② a new equation was derived to calculate the mutual diffusivity at different conce.

A samll and convenient measuring apparatus for determination of gaseous diffusion coefficients was built based on quasi-steady-state one dimensional diffusion.
