Introduction Production of bulk nanocrystalline materials is a challenging task in designing new functional materials.
Ni diffusion in both materials was found to be similar.
By this grain growth, at the same time, the GB structure closely adopts that one of GBs in coarse-grained material, as indicated by the similarity of Fe or Ni GB self-diffusion in both materials [5,6].
This fact supports the conclusion that the diffusivities of the nanocrystalline (d~100nm) and coarse-grained (d~0.5mm) materials are very similar.

When this ratio exceeds 0.8, the material is considered usable.

The original microfabrication techniques were derived from the semiconductor industry and the major substrate materials in the late 90’s were silicon and glass.
To obtain the goal of developing a microfluidic device that is low-cost, disposable, less hazardous fabrication processes, and mass produced, new substrate materials with associated fabrication techniques were explored such as polycarbonate, poly(methylmethacrylate) (PMMA), polydimethyl-siloxane (PDMS), and even paper [2].
Since micromilling is following the design pattern to remove materials from the substrate, so it can be used on different substrate materials from polymers to metals and create more possibilities in microstructure patterns and applications.
Brass is selected as the substrate material for micromilling since it is easy to machine and its strength is enough for hot embossing [20-21].

Giving full play to the advantages of base is necessary for the sustainable development of residential areas; Living buildings and the environment are the inseparable parts, among which some indexes are more standards in principle; Paying attention to resource recovery and recycling, as well as energy saving and renewable resources (Water, energy, land and material saving); Each system stresses on water resources regeneration and utilization, waste water collection and management and water saving; Energy efficiency and renewable resource utilization are both important; Put emphasis on protecting the ecology environment of residential areas, reasonable traffic organization and reduction of energy consumption brought about by traffic.
Application of new-type walling materials should also be considered in the item.
Therefore, the index setting should integrate the local materials utilization, resource recycling and environmental protection materials utilization for appropriate classification.
