Thus we should make full use of existing resources and science and technology to serve for the circular agriculture.
In order to realize the sustainable development of agricultural production, it should base on modern high technologies as the support and guidance, such as new energy material technology, information technology, biotechnology and so on.
New energy material technology provides new energy surpport system for circular agriculture, to reduce the dependence on the traditional carbonaceous energy and optimize the ecological environment.

With the devices miniaturization, the properties of materials at the micro/nano scale were much different from what at Macro-scale because of the scale effect.
The properties of materials at the micro/nano scale were much different from what at macro-scale because of the scale effect, when the thickness of the material was small to nanometers, and it was very difficult to measure the thermophysical properties of material by using experiment method [1].

Due to the growing application of 3D-printed materials at elevated temperatures, this study aims to characterize the tensile strength of TPU 3D-printed materials when thermal-cycled.
The TPU 3D-printed parts have the greatest toughness and abrasion resistance of all elastomeric materials.

The total amount of fat, protein and carbonhydrate is over 90% for all the samples and high content of fat and protein indicates that KW can be used as the raw materials for feed process.
Materials and Methods KW from different catering types (oversize restaurant, large restaurant, medium restaurant small restaurant, canteen, noshery, snack bar and drink shop) in Shanghai was sampled for each season in a year. 24 sampling points were set in Shanghai and samples were obtained in continuous three days.
