However, the key technology and materials still need a larger breakthrough to achieve large-scale application.
Working electrode materials were consisted of raw bord, Pt-modified bord and Pt-modified felt (thickness 3mm).
So felt was more suitable as working electrode materials.

Micro-electrolysis method can treat wastes with processes of wastes against one another because its raw material is abandoned scrap iron, the generated Fe2+ in the micro electrolytic process can act as the raw material of the Fenton oxidation process and the PH requested by micro electrolysis process and Fenton oxidation process are almost same, thus the collocational method of the two methods can save the acid and alkali used in the adjustment process of pH .
Experimental materials and methods Wastewater The water sample used in the experiment was from the medium pulping stage of a paper mill in Shandong province, the quality of the wastewater was as follows: Chrominance was 240 times, COD was 1360 mg·L-1 and pH was 6.

Concerning the fabrication and performance study of point defect for three dimensional photonic crystals in electromagnetic wave band, E.Ozbay has obtained point defect photonic crystals with woodpile structure in order to test their effect on photonic band gaps by fabricating some rods with metallic materials.
In conventional direct SL method, the materials used are very limited, the sintering shrinkage is larger than 30%, and the tested and simulated of band gap could have large difference.

According to OECD, resource productivity is defined as the quantity of output produced per unit of materials inputs used in the production of the output.
Material intensity indicators are the inverse of productivity indicators, so the energy intensity(EI) can be defined by: Material Intensity, and GDP represents the development of society and EC represents the total consumption of energy such as coal, oil, and gas etc.
