Silica (SiO2) consists of two elements that are more abundant on the earth (silicon and oxygen) and form 59% of the mass of Earth’s crust it’s the main constituent of more than 95 % of rocks The crystal structure of silica consists of three crystalline types: quartz (more abundant), tridymite, and cristobalite [2].

An understanding of phase constituents, growth kinetics and properties of the interaction layers that develop in the U-Mo-Al system can provide optimized materials chemistry and processing parameters to improve the performance and service life of U-Mo/Al monolithic and dispersion fuels.
Electron diffraction from both structures found are presented in Figure 7.

The deposited Ag NP ink also featured a more compact structure as the concentration of Ag nanoparticles was increased.

As described in [1], an optimal distribution of the cathode catalyst layer structure in PEM fuel cells has been achieved through mathematical modeling and the comparison between modeling and experimental results are verified as shown in Figure 2.
