Introduction DMSs are semiconducting materials in which a fraction of the host cations can be substitutionally replaced by magnetic ions or appropriate rare earths.
Some studies have revealed that Mn-doped ZnO materials exhibit different magnetic behaviors under the influences of the fabrication conditions and sample processing, which has been list in Table 1.

With local materials in a certain condition, new, cheap backfilling materials are developed.
So the development of new filling materials is in urgent need.
The choice of backfilling materials Generally, the slurry used in fire preventing and extinguishing technique is a mixture of clay and cement slurry.
On condition of large-scale coal combustion zone, this experiment chooses other cheap materials to develop inexpensive and effective grouting materials.
There is a large number of loess and clay around the coal mine, which could be used as basic materials.

This article makes a detailed introduction about the setup and tests a kind of typical materials of aero-engine hot end components.
Conclusions An experimental setup to measure TCC that is suitable for structural materials of hot end of aeroengine was introduced; TCC between typical structural materials TC4/30CrMnSi was tested, and its influence factors such as load size, processes of loading and unloading were studied; The results show that when the temperature of interface is fixed, TCC increases with the load, and is greater in the process of unloading than loading under the same condition.

Introduction A thermoelectric module comprises p-type and n-type semiconductor legs sandwiched between two ceramic hot and cold dielectric materials and connected thermally in parallel and electrically in series.
In our model, the temperature dependency of all the important properties of the “n” and “p” type semi-conductor materials was considered.
The electrical current is highly influenced by the temperature dependent thermoelectric materials, the, the external load (), and the hot and cold junction temperatures ( of the thermoelectric module.
The resistance wire silicon rubber heater was stick to the module using adhesive materials.
