This improvement is related to a change of grain size/morphology, chemistry of intergranular phase, SiC particles distribution, and structure and chemistry of grain boundaries.
They hinder the grain growth of the Si3N4, changing the shape and chemistry of the grain boundaries and grain boundary phases.

Exposure of mild steel to marine environments often results into dilapidation of physical structure over time.
The materials chemistry of the developed alloy was examined using open circuit potential and linear polarization technique.
The hexagonal structure of zinc was also responsible for most of the diffraction lines in the phase presented in figures 3 and 4.
A comparative study on the tribological behavior of nanocrystalline nickel and cobalt coatings correlated with grain size and phase structure.

Tung oil anhydride-ester polyol (TOAEP), prepared from the China special vegetable oil, Tung oil, was introduced into PU structure.
The mechanical property, heat-resistance and morphological structure of the modified PU were studied.
The main reason is probably that the reaction of polyurethane prepolymer’s –NCO group and TOAEP’s –OH group has formed crosslinking structure, and this structure leads to the increase of physical crosslinking points and improves the crosslinking density of PU.

Transmission electron microscopy revealed that ripe CQDs synthesized at these temperatures (rCQDs-100 and rCQDs-200, respectively) possessed disk-shaped and quasi-spherical structures with particle size range of 1.71-5.05 nm and 1.55-4.66 nm, respectively.
The similar intensities of the groups present in rCQDs are strong indications that the crystalline cellulosic structure of the precursor was not disrupted during the carbonization process.

X-ray diffraction of the synthesized ZnO shows hexagonal zincite structure.
Nano-sized ZnO is transparent, with crystals commonly found in hexagonal wurtzite structure.
In this structure, Zn is tetrahedrally bonded to O, and the lack of centre of symmetry gives rise to piezoelectricity [2].
Figure 3 shows the scan in a smaller range between 30 to 40° in order to study three strongest peaks at (100), (002) and (101) which correspond to hexagonal wurtzite structure of ZnO.
