Recycle Economy is the “three sides win” economy Compare with traditional economy, recycle economy is a new concept which changes the operational sequence of technology and industry rather than simply using the old materials and it conserves resources.
In addition, it is necessary to concentrate on recovery and deal with those materials which cannot be reused to achieve multi-level resources and closed virtuous circle of waster.
Due to the small response of the enterprises to recycle economy, the recovery and reuse of waste materials can not be effectively implemented, which bring little effect on enhancing social employment [6]
The first and foremost step to develop recycle economy is to have a fundamental change in the view of waste materials; they must be seen as resources.

Of Aeronautical Materials, Beijing 100095, China lishs@buaa.edu.cn Keywords: alloy IC6AE; Ni3Al; NiCr-CrAl coating; oxidation resistance, hot corrosion resistance Abstract: The effect of NiCr-CrAl coating on the microstructure, oxidation and corrosion resistance, as well as mechanical properties of Ni3Al base alloy IC6AE has been studied in the present investigation.
Introduction Structural materials used in advanced jet engines at high temperatures must have good oxidation and hot corrosion resistance and mechanical properties [1].
Howeve, few materials can meet these requirements simultaneously, therefore the coating protection is usually needed.

Introduction Polyvinylidene fluoride (PVDF) has been widely used as one of the membrane materials, well-known for its excellent chemical resistance and thermal stability.
Domestic scientists have done a lot of researches about modification of PVDF membrane [13-16], which indicates that graft modification and blending of membrane materials are the main direction of future development of the hydrophilic membrane.
PVDF was purchased from Shanghai 3F New Material Co., Ltd., China.

Apparently, materials undergo dynamic recrystallization (DRX) during FSP.
The resulting grain sizes in such materials may be in the range of 10–1000 nm.

Introduction Metal nanoparticles (NPs) are applied in several fields of biotechnology, nanobiotechnology, material science, medicine, etc. [1].
Methods and Materials Plant sampling, identification and extraction procedure Arial parts of S. suffruticosa were collected from Lalehzar Mountain (40R05435550, UTM3327896) in Kerman Province in 2018.
In comparison with bulk parental materials, NPs such as AgNPs have unique physiochemical properties such as size and shape (1–100 nm diameter) and greater surface area to volume ratio that lead to the higher chemical reactivity of these NPs [39].

Materials and Methods We collected 100 kg of EAFD and 100 kg of hot metal in industries in Espírito Santo state as follows: Electric arc furnace dust: ArcelorMittal/Cariacica, and Hot metal: Fundição Ucrânia located in the municipality of Serra.
In possession of raw materials, the next step was the chemical and physical characterization of the main raw materials through various characterization techniques, they are: Analysis chemistry; analysis particle size; area specific surface; designation of the form of dust particles by optical microscopy and scanning electron microscopy; analysis by energy dispersion, and X-ray diffraction.
