Dyamant et al.[2] studied glasses in the system SiO2–Bi2O3–ZnO–B2O3 and concluded that glass formation was obtained within the composition range of 40–60 mol% SiO2, 1–30 mol% B2O3, 10–45 mol% Bi2O3, and 1–35 mol% ZnO, with glass transition temperature (Tg) in the range of 411–522℃, which decreased with the increase of Bi2O3 content, and dilatometric softening point ranging from 453 to 563℃.

This reaction can be described as 2H2O® O2 + 4H+ + 4e- (3) According to McLaughlin et al [15], the dynamic performance of the device can be predicted by solving the diffusion equation using an applied voltage step, independent of the electrode size and geometry.

Valdevit el al. studied the bending response of steel sandwich panels with corrugated cores subjected to bending loads, presenting relevant design variables for optimization processes [12].The need of using light and stiff structures balances the need of study of structural solutions based on sandwich geometries, involving in this case numerical analysis.
