Lead Iodide (PbI2) is a direct band-gap semiconductor compound and one of the most promising materials for γ-ray and X-ray detectors.
Also, the recently published results reported on the influence of rare earth (RE) elements on the quality of materials for radiation detectors [1].

The need to combine different materials not welded together, such as metals and composites fiber reinforced, is now very much felt industry.
Joining of composite materials has traditionally been achieved by mechanical fastening or adhesive bonding.
Comparing the SPR technique with conventional methods of connecting material of small thickness, we can list the following the benefits offered by it: · Possible connection of different materials and multiple layers of material
The mechanical properties of the two materials were preliminary obtained through tensile tests, performed according to ASTM standards.

The earth-dwelling caves deeply hidden in the layers of loess are a living place dug from the underground “infinite body” of primary soil, which is different from those ground buildings of volume space made from building materials.
Except primary loess, people hardly use other building materials in constructing earth-dwellings, which not only saves natural resources but makes little environmental pollution as well.
Using immature soil as building material to get local material and adopting the method of subtraction in construction, works cost is only spent on the “labor” without material considered.
