But it is not very convenient in producing and using the beam slabs due to the limited space of the transferring columns, and the pedestals will be constructed in large quantities of materials, then the cost is much higher.
The width of a pedestal unit must include two production lines at least, and the space of the beams and materials to be transferred should take into account.
The width of road for transporting materials shall be determined by the construction equipment as well.

The fixation of CO2 to polymeric materials for the application in industrial field is one of the most valuable researches for the 21st century considering the environmental issues [1,2].
However, tedious procedures of DMC preparation in the conventional solvent-based ways are time-, energy- and materials-consuming.

Introduction
Since Reinitzer first reported in 1888 that cholesteryl benzoate displays liquid crystalline behaviour, cholesteric liquid crystals (LCs) have had many applications as electro-optic materials in thin film devices.
