The product range was broadened and extended to other fields (covering powders for ladle and tundish) which led to an ever-growing number of powder recipes and a greater demand for quality production.
Fine powder is mechanical mixture of dry, fine-grained and insulating material which mainly consists of SiO2 and CaO.

The numbers denote the size variations of the fragments (X20, X50, and X80), while the uniformity index (n) tracks how fragmented the product is.
During the first PF range (0.30 < PF < 0.52), as PF generally improved the loading efficiency, the fewer-grained the fragmentation the less resistance during scooping and more rapid filling of the bucket and decreased bucket cycle time.

However, RH(T) values with the expected sign were observed in microcrystalline Si with a grain size as small as 3 − 5 nm [28, 32] and in a-Si:H in which extended states (i.e., delocalized states) were the dominant contributor to the resistivity [33].

In ballistics, the material properties of concrete as the compressive and tensile strength of the matrix, type, and size of aggregate, steel bar spacing, position and the number of layers, and possible fiber type, content, tensile and bond strength of fibre, and its orientation determine the ballistic performance [4].
The projectile penetration is related to the Janka hardness of the target material and the direction of the wood grain [23,25].

As shown in Fig. 3(c), a huge number of light gray needle-like TiO2-TiNb2O7 plates (the ratio of TiO2/TiNb2O7 was 2.998) (“8”) and hillock-like Y2O3-SiO2 particles (“9”) distributed disorderly in the glass-like Cr-rich SiO2-Al2O3 matrix (“7”).
Since the free energy of Y2O3 was the lowest among the oxides formed in the scale, then at the initial stage of oxidation process Y2O3 was preferentially formed in the grain boundary where Y atoms with large dimension gathered originally.

Microspheres have surface morphologies and internal structures, which include density or porosity, pore size, pore interconnectivity, phase composition, grain size, chemical composition, etc.
The limited number of BMSCs was due to the short cell culture time (3 days).

Although the number of metals and cycling stability can be increased, this does not enhance the stack capacitance or areal capacitance.
The virtually square planar shape of the Zr NPs aggregated with grain sizes of less than 90 nm is shown in Fig. 2 (a).

Initially, the ZnO crystalline grains mainly grow along the <0110> direction due to epitaxy.
Figure 6 shows the HRTEM image of silver nanoparticles deposited on the ZnO 1D rod, and was indexed assuming Fm-3m symmetry obtaining a unit cell value of 4.09 Å in agreement with the data reported for the JCPDS card number 065-2871.

Besides, it involves a higher number of experiments for determining the optimal conditions.
N=2n-1+2n+nc (2) Where N, n, and nc are the number of experiments, the number of process variables, and the number of center points.
The transformation of predicted responses to unit values with boundary conditions values between 0 and 1 is a prerequisite for the desirability process, which requires higher dr values and a higher number of responses [42].
The increase could be because at high temperatures, a large number of heavy metals tend to be in collision with the active sites of the adsorbent which in turn forms complexes around their structure [44].

A third term is introduced into the LDD model now, describing non-diffusing impurities caused for instance by dopant trapping at grain boundaries or at lattice sites in the sample volume, dopant reacting (absorption) with other species of the host lattice system or clustering.
Comparing TEM pictures in Fig 5b-d with Fig. 5a, an increasing thermal budget reduces the number of host lattice distortion clusters and forms lager clusters located in a range of about 2 nm to 14 nm under the surface, in agreement to the a) b) c) d) Figure 4 SIMS spectra of SiGe/Si films (a) and boron diffusion of samples according to Tab. 1.
