The increased cation vacancy concentration at the interface of the dispersoid and the grains of the host matrices led to highly conducting interfacial layer and increased the lattice defect.
This could be due to increased number of cation vacancies in the space charge region resulting in less energy required for anion mobility [18].

The grains are
uniformly distributed and well dispersive when using MSC method (Fig. 2a), but not uniformly
distributed and badly agglomerated when using CSC method (Fig. 2b).

Namely, when the tip of a propagating crack meets a coating
element (e.g. grain) with toughness exceeding the energy release rate (ERR) available, the crack
becomes arrested.
Clearly, the number of such arrest events and thus the extent of quasi-stable crack growth depends on the ERR and the scatter of coating toughness.

Over the past few decades, a considerable number of studies have been conducted on the effects of industrial by-products, such as fly ash, silica fume, and ground granulated blastfurnace slag, on the mechanical properties and durability of the cementitious composites and the usage of those by-products in composites had a great influence on improvement its performances.
In conclusion, the inclusion of 10% SBA with the grain sizes capable of passing through a #325 sieve (45 μm) in composites had a better benefit on compressive strength.

The pattern is composed of a number of spots corresponding to (-302) and (-202) planes of the crystalline plate.
When the temperature is relatively high, the MoO2 vapor tends to form large grain crystal, so nanoplates are gradually formed.

Recently, the DSC model has been published in a number of papers [3-7].
The relative densities, Dr, of standard Ottawa sand (mean grain size D50 = 0.6 mm) specimens are 20% and 90% to analyze the responses of loose and dense sand specimens under triaxial compression test.

The ecological environment quality evaluation based on the comprehensive index. comprehensive index method is using the weight of each evaluation factor and dimensionless value of each evaluation factor weighted evaluation results are obtained, formula is as follows:
Compared in 1996 and 2004, per capita grain and sunshine time reduced, which is also one reason for the difference between them.
