A key technology that help sharing information in a secure mode is blockchain.
This is the point in which every company looks for circular economy model of development (prevent-reuse-recycle-recover-dispose pattern) trying to take the advantages of global reverse networks, reorganizing the materials flows, bringing innovations in business models with the help of technology and human kind cooperation [12].

Performances of materials are determined by their microstructures, including categories of phases and morphologies.
However, microstructure of materials is decided by conditions in the process of solidification.
In the preset MCrAlY coating process through laser cladding plasma spraying, energies firstly accumulate in thin materials on surface, and then are transferred into materials through heat conduction.
Thermophysical parameters of materials.

STUDY OF THERMO-RHEOLOGY CHARACTERS OF ROCK UNDER THE UNI-AXIAL COMPRESSION Wang C.G.1 , Song Z.Q. 1, Chen W.Z 2, Liu Q.S. 2, Yang C.H.2 1 Shandong University of Science and Technology, Taian 271019,China 2 Institute of Rock and Soil Mechanics, The Chinese Academy of Sciences, Wuhan 430071,China Key words: Rock, Compression, Thermo-rheology This paper introduces temperature effect to rock model.
If the rock's complex property, such as mineral crystal, pore, water and joints, is considered, it will be extremely sophisticated and difficult to apply in engineer projects.
In practice, rock can be looked as one kind of thermo-visco-elasto-plastic material.

For comparison with other materials, similar grammages and weaving styles were selected.
However, the advantage is the lower density of flax materials and possible weight savings.
Similar values for comparable materials have also been reported by other scientific papers.
The specific strength demonstrated that flax materials achieve better values than glass materials.
