Triethylenetetramine (TETA) modification enabled the effective grafting of an amino group onto the surface of the materials and their pore structure.
MOF materials also have many advantages over traditional porous materials, such as activated carbon and zeolite molecular sieve; these advantages include structure designability, functional diversification, and high specific surface area and pore volume.
Scholars constantly conduct studies on the application of MOF materials in adsorption and separation, shedding light on emerging high-performance MOF materials.
Consequently, the crystallinity of the materials decreased.

Preservation of materials using liquid nitrogen media has been widely used.
One way to increase the resistance value of the layer is by combining this material with other materials [1].
Among the recommended materials are nickel-iron or copper-nickel [2].
Both materials are types of transition metals.
Materials commonly used in the industrial world are nickel, copper and platinum.

Under the background, the scholars presented the new idea of MMC based on the retrospect of mechanical science and intelligent system's development process.
MMC manipulator takes full advantage of the idea's advancement, solves the problems that material carrying vehicle can not position accurately in MMC material handling system, have some practical meanings.
Material handling surroundings means the whole MMC material handling system, including CNC machine in the system, material carrying vehicle, MMC manipulator, man etc.
As shown in Fig.2 [4], the feeding and unloading process work as follows: When the material carrying vehicle arrived at the destination, MMC manipulator detected the exact position of material firstly, moved in the direction of it and picked up the material.

Over the past several decades, a variety of cumulative damage theories have been developed for metallic materials.
An anisotropic damage model of quasi-brittle materials and a two-scale damage model for HCF of metallic materials are studied by Desmorat, and numerical simulation method was obtained[13,14].

Furthermore, for this analysis, the materials used for the cutting tool were Tungsten with an elastic modulus E = 4.096e+011 Pa, shear modulus G = 1.6e+011 Pa, Poisson’s ratio µ = 0.28, and density ρ = 19300 kg/m3.
The stiffer the materials, the shorter will be the duration of the pulse and the higher will be the frequency range covered by the impact.
