The formation of metatitanic acid in the thermal hydrolysis of TiOSO4 by self-generating seeded goes through a series of steps involving ionic reaction, olation and oxolation, nucleation, grain growth and aggregate to the final form [6].
The Volume ratio of pre-adding water to TiOSO4 solution influenced the number and activity of the seed crystal, thereby influenced nucleation, crystallization and aggregation process, eventually determined morphology and pigment properties of the product.
With rising pre-adding volume ratio, number and activity and dispersion of seed crystals increased [9] bringing about the formation rate of initial nuclei and secondary nuclei enlarging, resulting in forming the smaller hydrated TiO2 particles.
Colloid Ti4+ accumulate gradually as the extension of time, homogeneous nucleation dominant, instantly generate a large number of nuclei and finer the primary particles, the rate of hydrolysis sharp increase.

Peaks at 522 and 976 cm-1 correspond to Si, the peak at 1332 cm-1 is related to diamond and the peaks at 1134 cm-1 and 1540 cm-1 are ascribed to the amorphous network (trans-polyacetylene at the grain boundaries).
Fig. 1b shows typical COF versus number of cycles curves recorded during the sliding tests on the NCD films against Si3N4.
number of peaks along the scan line) were obtained from it and are reported in Table 1.
A number of grooves on the NCD surface decreases from Fig. 2a to Fig. 2c and only two grooves can be found in Fig. 2c.
Therefore, the number of grooves decreases with increasing frequency (from 2 Hz to 10 Hz) and sliding distance (from 14 400 to 108 000 cycles).

Al2O3-Fe-based cermet is the introduction of iron particles into the ceramic matrix, which greatly refine the Al2O3 grain, and enhance the toughness and strength of ceramics, has great practical significance [3, 4].

This annealing step resulted in Ni grains of 20 and 50 µm average grain size for 30 and 60 minutes of thermal annealing, respectively.
It has also been shown that the shape and relative intensities of the G-, D- and D’-peaks depend markedly on the number of layers.
Biocompatibility, health and safety Graphene has been linked to a number of numerous potential applications.
Another significant issue regarding biological compatibility is the number of graphene layers.
The adsorptive capacity for any specific biological molecule is expected to decrease significantly as the number of layers increases.

The original location of the gray-black strip-like phase, thus the distribution of particles between the large number of white block inter-metallic compounds (Fig. 4b).
Inside, the ferrite matrix composites only a small part of the edge grain in WC particle melting generated Fe3W3C, WC particles in the pearlite matrix composites are almost melting, and the melting of W2C and Fe, C reaction generated Fe3W3C spread to the entire matrix, therefore, the degree of W2C melting and the formation of Fe3W3C are closely related to the C content in the matrix.
When the direction of force and the interface at the vertical, the interface will appear at the interface of micro-cracks eventually form micro-pores, resulting in cracks along the grain boundary tear.
A large number of cracks at the interface and the presence of pores in the original material reduce the effective bearing area of the material, and ultimately lead to fracture failure of the material.
The ferrite matrix composites have relatively complete interface phase, and the rate of micro-cracks growing up in the compression process is slow and the number of cracks is significantly reduced and does not fill the whole matrix (as shown in Fig. 10a), showing a better comprehensive mechanical properties.

(2) Fiber-reinforced asphalt concrete AC-13 (type-B) When the times came to 2178, the first cracks appeared, the width of cracks was small and the number of the fine cracks increased. while the times were up to 16941, the cracks run through overlays, which showed that fiber was effective to improve the anti-cracking performance of asphalt concrete for fatigue to some extent

In this paper, we collect the data through the API of twitter and mine information spreading based on users retweet behavior at a coarse-grained level.
We define retweet-width as following: it’s the number of retweet behavior of a tweet at one level.
But we do not count B’s retweet number as A’s retweet-width.
Only 110 tweets achieve that number.
First we know that the number of tweets based on each depth is different.

Since the available computer hardware limits the number of degrees of freedom, not the whole structure can be meshed.
In the Monte Carlo calculation, a fine grained square planar lattice (151 x 151) with standard periodic boundaries containing a single circle or square representing the inclusion is employed thereby implying a square planar arrangement of the inclusions.
The number of particles released is typically 10 6 and this provides the ensemble average as required in Eq. 5.
The number of time steps per particle used in the present calculations to ensure long-time behavior was 2 x 10 6 for the case analyzed here where the conductivities did not differ by more than an order of magnitude.
The source and sink planes are separated by some 100 planes in the +x direction and by the same number of planes via the periodic boundary in the -x direction.

Table 1 Experimental conditions Fig. 1 Configurations of workpiece On the surface of work plate of ultrafine grain cemented carbide (Sumitomo Hard Metal, AF1), square grooves or 90 degree V-grooves were ground, as illustrated in Fig. 1.
Fig. 5 Depth of groove for various experiments Groove number (c) S series Groove number (d) SN series (b) VN series (a) V series Fig. 2 shows the average grinding forces where the mean value of the average grinding forces of 1st, 10th, 20th, 30th ,40th and 50th groove and its variation are plotted.
In many cases, the depth of groove does not change along with the groove number, therefore in those cases the wheel wear was considered small.
In case of V5, VN5, S5 and SN5, however, the depth of groove apparently decreases with an increase of the groove number.
The radius of corner generally increased within the variation with an increase of groove number.
