For MnAs films grown by molecular beam epitaxy on GaAs, the phase separation process leads to a self-organized structure on the sub-micron scale with alternating ferromagnetic and non-ferromagnetic stripes [2].
Using spontaneous self-organization effects is an efficient way to produce nano-structures, as for instance quantum wires and quantum dots [6].
They were crystal clusters, linear structures, and circular-shaped aggregates.

However, the researches on SO42-/SnO2, not only in its structure but also in applications, are relatively few [11-16], this is mainly because the preparation of Sn-based super acids is more difficult than that of Zr- or Ti-based super acids.
According to literature[17], there will be peaks near 997, 1060, 1130, 1211 cm-1 when sulfate and metal ion, such as Zr4+, Al3+ form bidentate structure.
In Figure 3, there is an obvious peak near 1410cm-1 in Curve a, maybe arisen by S=O vibration from sulfate and Sn of the bidentate structure.

But there are still a certain degree of defects, such as salts deposition and corrosion on the upper hot zone walls, the lack of cooling structures leading to reactors wall overtemperature, the poor ignition and flame stability due to without enough heat storage spaces and so on.
The effects of mixer structure on the hydrothermal flame ignition characteristics of isopropyl alcohol were also researched, which indicated that optimization and design of the mixer could effectively lower the ignition temperatures of isopropyl alcohol.
Although existing SCHC reactors can be used for studying the ignition and extinction characteristics of various fuels, also show their effectiveness for the pollutant disposals, but there are still a certain degree of defects, such as the lack of cooling structures and enough heat storage spaces and so on.
