There are a Mercury oxide aircraft, which is a responsible for the high critical temperature superconducting material [7].
Methodology Using a sensitive scale, pure powders contain mercury, calcium, copper, strontium and yttrium oxides were weighed to synthesize samples with a chemical formula HgSr2-xYxCa2Cu3O8+δ, with x-ratios changed from 0 to 0.15 by the solid-state reaction method, as starting materials, according to chemical formulas: 2HgO + 4CaO+ 6CuO+2(2-x) SrO + x Y2O3 →2 HgSr2-xYxCa2Cu3O8+δ Each elements were accurately weighed.

Introduction Titanium dioxide (TiO2) has gained considerable attention because of its excellent photocatalytic activity, chemical stability, non-toxicity, favorable optoelectronic property low cost [1] and its importance in a diverse range of applications such as functional materials for energy conversion, photocatalytic, photovoltaic, antibacterial, self-cleaning and sensing applications [2].
In particular, TiO2 nanotube arrays fabricated by potential anodization of titanium constitute a material architecture that offers a large internal surface area without a concomitant decrease in geometric and structural order.
