The microstructures of the phosphor consisted of regular fine grains with an average size of about 0.7-2.5 μm.

This model is corresponding to emission of thermal carrier across grain boundary where the conductivity is anticipated to be linear with temperature [12].
The carrier concentration in this temperature range is number of ionized donor liberated from impurity levels.

Generally speaking, the distribution of NiFe grains with various orientations is different for NiFe films deposited on different buffer layer [6].
Therefore the number of domain walls and domains present for an irradiated sample is increased compared to the non-irradiated case which results in an enhancement of the exchange bias field according to Malozemoff's model [8].

The Sol-gel process is one of the most promising methods, which has the benefit of phase and structure homogeneity; finer grain microstructure and lower temperature of crystallisation.
Therefore, the HA coated Ti-Nb sample exhibited better in-vitro bioactivity. 0 2000 4000 6000 8000 10000 12000 14000 Cell number Well Ti-Nb sample Well+sample Coated Ti-Nb Uncoated Ti-Nb Figure 3.

The polymer precursor impregnation pyrolysis (PIP) process was also used to fabricate the C/SiC brake materials by the four brake companies in the US [4], however, the PIP process not only resulted in a large number of micro-cracks and pores in the ceramic matrix for pyrolysis but led to a long manufacturing cycle for obtain the dense composites.
The SiC was probably damaged by fatigue: the SiC grains debonded and so fibers loosed by repeated flexion, as shown in Fig.4 (b).

Fig.2 Multi-stations pin-on-disk wear testing machine Results and Discussion The variation of mean weight loss (wear) of UHMWPE pins against alumina, zirconia and zirconia/alumina composite disks during the entire test duration was plotted in Fig. 3(a) as a function of number of cycles and two different kinematic motions.
This can be interpreted by that micro pitting wear of ceramic surface occurs through the fatigue grain boundary failure under the cyclic contact stress.

ECC can avoid heating up the powder bringing on Grain Growth or Crystallization, so it can manufacture not only groovy metal or nonmetal coating but also nano or amorphous coating.

The median particles of a given grain size in a given area.
It may be assumed that the reverse micelle aggregates present in the solution are not affected by the addition of TEOS molecules or by subsequent reactions, and in particular that the aggregation numbers of the micelles remain unchanged.

It is limited by the number of tetravalent titanium ions, but not the octahedral or tetrahedral sites to accommodate lithium ions in the voltage range of 2.5 to 0.01V, corresponding to 293 mAhg-1, but not 175mAhg-1[2].
The scanning electron microscope (SEM) was used to observe the grain morphology and particle size.

Was effective at lower temperatures, the matrix dislocation density produced lower back, reducing the space, so the conductivity increases slowly, after the aging temperature over 400℃, γ-Fe precipitates lead to a large number of materials, the conductivity rapidly.
It should be noted that the conductivity of the peak temperature is higher than the corresponding age-hardening peak corresponding to the temperature, mainly because, with increasing temperature, precipitation coarsening of γ-Fe particles and matrix grain growth continues to increase the conductivity of the material.
