Tests of ergosterol, which is a component of most fungi’s cell membrane, allow us to monitor the level of fungi infestation of diverse materials.
Modern methods used to identify the presence of fungi in, among other things, construction materials, are based on e.g. ergosterol determination.
The use of ergosterol to monitor the level of fungi infestation in materials is the subject of many analyses.
During the conservation and restoration of antique floors it is important to pay special attention to preventive measures related to materials and structures.

Thus, the tested specimens can be approximately considered as continuous material.
X-ray diffraction analysis Summary (1) Vacuum Spray fusing obviates the oxidization with bonding interface of different materials, and increases the combination intensity of coating and substrate.
It can be further noted two different materials are together superplastic deformed simultaneously.
(3) Whether or not the two different component materials of the coating and the substrate can realize the superplastic welding?

This research group used inexpensive river sands as packing materials, and used ozone non-continuous aeration to form an activated film on the surface of river sands with stable manganese removal ability.
Inexpensive river sands were used as packing materials of the filter.
