Firstly, a multi-level ontology model of materials is found which is expressed in OWL as an ontology collection of describing places ages and events and associated properties among them.
Definition and partition of multi-level ontology model According to the difference of materials production and their controlling requirements, this article has defined 4-level monitoring model.
Multi-level materials monitoring model is shown as Fig.1.

To implement the power self-generate function, we make an important change on the component of leaf springs which we setting piezoelectric materials on both sides of the spring.
With vibration of leaf springs, mechanical vibration energy will transform to pressure on piezoelectric materials and therefore micro-current will be came into being.
piezoelectric materials leaf spring Fig.2 Structure of piezoelectric leaf spring Conclusion Power supply for micro-system such as wireless sensor network node is an open and interest issue.
Energy harvesting using piezoelectric materials- Case of random vibrations.

Liquid co-precipitation method was applied to produce LiFePO4 cathode materials in which Ferrous carbonate was used as raw material.
A coin-type (size2032) cell was used to investigate the electrochemical performance of the obtained active materials.

Abstract: This article focuses on the compression strength of lightweight concrete based on alkaline-activated waste materials.
Material and Experiment The aim of modern science is to use waste for the production of products in order to minimize their storage and ultimately lead to the replacement of natural raw materials with secondary ones.
They are based on waste materials and are therefore an alternative to the use of natural resources.

The ultrasonic cutting of composite materials has the advantages such as high processing efficiency, high precision and non-pollution.
In the whole ultrasonic cutting system, tool is used to directly cut materials, which make higher requirements to the research and manufacture of tool. 2.
The sharp circular tool, good technique effect and high processing efficiency meet the processing requirements of honeycomb-like interlayer composite materials. 6.
