Moreover, due to the compaction during transition from Fe2Si to Fe3Si, excess silicon is formed, which is released (segregates) on the film surface and the grain boundaries of the film.

Grain size was respectively determined by the Eq. (1).
The FTIR spectrum for HA-120 shows the peaks for P-O vibrations in the phosphate group at wave number 471.4; 567.1; 602.9; 963.0; 1027,5-1099,5; 2002 and 2077 cm-1, while the O-H group at 631.6; and 3571.1 cm-1, and the CO32- group at 875.4; 1420.5 and 1458.1 cm-1.

Studies on chemical composition highlighted that the Green Tuff consists primarily of phillipsite, pyrogenic K-feldspar, and clay minerals, with minor analcime and calcite merged in fine-grained matrix as reported in ref [8].
The number of the analysed samples was enough to ensure statistical significance.

Furthermore, substantial twinning can significantly refine the grains, increasing the number of pathways and decreasing the effective glide distances for dislocation slips, thereby preventing local s concentration, improving the elongation-to-failure, and increasing the work-hardening rate.

Introduction Over a number of decades, considerable effort has been made towards the development of lightweight engineering materials.

They were previously sorted according to their maximum grain size and cleaned from any impurities such as metal and textile parts.
A number of 10 cylinders, 100 mm × 200 mm, was cast for each mix for a total of 20 samples.

There are a large number of publications on new composite construction materials (see review in [3]) but all of them only focus on either synthesis of the materials [5-7] or theoretical calculation of elastic moduli [6] or finite element modeling of their behavior under uniaxial compression [7] or destructive and semi-destructive tests [8].
Granite gravel (grain size: 8 to 15mm) was used as aggregate for concrete.

Beginning from the surface, the hardness profile characterizing the hybrid welding introduces instead lower hardness with respect to those of the laser welding for around the 60% of the thickness of the sheet, probably because of the greatest heat input of the MIG (77% of the supplied total power) to which smaller speeds of solidification are associated that results in the formation of a structure with larger grain.

A sensor node might vary in size from that of a shoebox down to the size of a grain of dust, although functioning "motes" of genuine microscopic dimensions have yet to be created.
WSNs are composed of a large number of sensor nodes, therefore, an algorithm for a WSN is implicitly a distributed algorithm.

The distributions of the pore size and wall size in the MBG specimens were measured from a number of TEM micrographs.
In this case, no significant grain boundary is observed, so that the region should have the same orientation; this result indicates the contrast of these micrographs is mainly contributed by thickness.
