The porous structure can be observed between the flakes.
The dimension of the porous structure in Ni(OH)2 was larger than diameter of MWNTs, so probably MWNTs can penetrate the porous structure.

Due to a magnetic restoring force, Fy, between the sphere and the centre magnet and wear-pad, vibration of the host structure (‘host vibration’) will result in oscillation of the sphere.

This grade of WC also has a fine grain structure, and contains a 6% cobalt binder making the wear-pad slightly ferromagnetic.

Among them, dibenzothiophene is often chosen as dibenzothiophene mimics for its typical structure [3-5].

Raman spectroscopy has been applied extensively as structure and diction probe and is one of the important methods to deeply study.
Raman spectroscopy yields detailed information about molecular vibrations, and Raman spectroscopy is useful not only in identifying molecules but also shedding light on molecular structures[3-4].
Some structure assignments were discussed in the observed spectra.

The same form of all spectra indicates that the ZrF4 glassforming structure is not significantly influenced by changes of the composition.
As this structure determines the ionic conductivity, the results of the Raman spectroscopy explain the similar ionic conductivity in our glasses.
The same form of Raman spectra for all our ZrF4-based glasses indicates that the ZrF4 glassforming structure is not significantly influenced by changes of the composition.

Among them, a metal selenide of the composition Er2Se3 with the Th3P4-type structure is of special interest as possible high-temperature thermoelectric and optoelectronic material [1,2].
As can be seen, the undoped film prepared with vacuum-assisted thermal evaporation has a polycrystalline structure.
All films have a cubic structure of Th3P4 type with a lattice constant of a = 8.52 Å and stoichiometric composition with uniform Er and Se distributions both on the surface and the inner part of the films.

The change of organic acids concentration are correlated with the surface structural characteristics of bentonites as well as the structure and conformation of organic acids.

The basic idea of Monte Carlo is: in order to solve the mathematics, physics ,chemistry and other problems, we can establish a probabilistic model or stochastic process, making the parameter be equal to the solution of the problem; when the solution of the problem itself belongs to the random question, according to the probability algorithms in actual physical construct the Monte Carlo model, and then the statistical characteristics of the unknown parameters will be calculated through observation of the model or sampling experiment, and finally an approximation of the solution will be given[2].
We usually use three indicators to measure it: structure importance, probability importance and relative probability importance [4].
Structure importance reflects how important each of the bottom events is in the fault tree from the perspective of the fault tree structure.
