The hot tearing susceptibility was increased with Zn additions due to the segregation of Zn element in grain boundaries.
A large number of shrinkage pores were found to be distributed in the interdendrites at the cooling rate of 0.3 °C/s.
With the cooling rate reduces, the intensity of diffraction peak corresponding to Mg17Al12 (b phase) in the alloy decreased slightly, while the number and intensity of the diffraction peak corresponding to Al11Ce3 show a significant increase.

The number of atoms in interfacial SiC, ZrB2, and SiC-ZrB2 interfacial supercells was 81, 216, and 297, respectively.
Due to complex crystal structure it is not possible to explicitly characterize the type of defects formed (screw vs. edge dislocation, the extent of individual bond rotations due to a large number of bond angle permutations involved etc.).

Over time there may be slight increase in the number of casualties, but the data still has some statistical significance.
For example, On May 23, 2007, the ship loaded with grain smoothly passed the Fang Bridge which has hundred years history.
Concerning a number of non-uniform aiding navigation in standards and the lack exposed in them, relevant departments should enhance the sense of responsibility and do their best to revise, improve and standardize the standards.

For nanocrystalline films the upward band bending is apparently mitigated by carriers provided by the sp2 bonded carbon in the grain boundaries [12].
Combined Photo-Induced and Thermionic Electron Emission For a number of energy conversion applications there is an advantage combining photo-induced emission and thermionic emission.

The choice of grids with mesh size larger than the grains is justified by ensuring the concrete matrix continuity, and therefore avoiding interface failure.

There is an increasing number of papers reporting the effect of several properties on photocatalytic performance of TiO2.
However, there is a wide range of other commercial titania products on the market, including Millennium PC 500, Hombikat UV 100, and Kerr-McGee, which differ in terms of grain size and phase composition.

Horstemeyer et al. [8] took single-crystal nickel to study studied the void growth and coalescence and discussed the effects of strain rate, atom number and temperature on plastic deformation and void extension; however, the effect of dislocations on void growth and condensation had not been discussed.

The general morphology, shape as well as grain size, were determined by field emission microscopy FESEM (SUPRA 55VP ZEISS).
However, the number of nanoflakes in S2b was higher than S2a.
Increasing the particles number will work on reducing the interfacial tension more due to Brownian motion [22, 23].

Large numbers of productive agriculture lands have ruined due to high concentration of salts, throughout reducing crop yields and decreasing soil fertility [1].
Measurement of physiochemical properties were done by weighing 20 g of previously prepared soil and vortex with 100 ml of distilled water for 30 minutes to extract all elements and salts such as pH, electrical conductivity (EC mS/cm) by using pH and EC meter (serial number: LPN HE 80533) after calibration.

Taking into account the large amount of literature on ZnO, it seems reasonable to assume that no other nanomaterial may compete with ZnO in terms of the number of realized morphologies, making it a preferred choice for various applications.
According to [36] ZnO can grow on the side surface of the hexagonal Zn grains in an ultra-low temperature range of 250–400°C.
