The effect of Er,Cr:YSGG laser for ablation of commercialized adhesive dental materials were studied using 12 sets of tooth samples.
Two adhesive materials, Grēngloo, and Blūgloo (Ormco Corporation, USA), were used.
Er,Cr:YSGG laser (Waterlase, USA) was used to remove adhesive materials layered on the enamel surface.
This might be due to the different composition of the element in both adhesive materials since reaction of materials toward laser highly depends on their chemical composition.
Acknowledgment Authors wish to thank all staffs at the School of Physics and science officers of Craniofacial and Biomaterial Sciences Cluster who actively involved in this research.

Lastly, the all materials are stirred in the mixing drum of paste and the paste is unloaded to pump truck HBT50C that is shown in fig.4. the paste material begins to cycle over three burdens, the burden experiment is completed.

It will change the status quo of the lack of dialogue between materials science with art, recycled materials from the point of view of public art, research and development, and applications make proactive in environmental design.
In this study, "renewable materials" mainly focused on the public art materials field, its scope and methods of public art.
Recycled materials include not only well-known natural renewable materials, but also include man-made biodegradable materials and life industrial recycled materials, which greatly enriched the scope of public art materials, and reflect the public geographical characteristics and diversity of the arts.
The Scope of Application of Recycled Materials in Public Art Uses of renewable natural materials.
Life, industrial recycled materials.

It points out that ecological environment material is one of the latest trends in development of material science and analyzes the current research trend of ecological environment material and Life Cycle Assessment (LCA) of materials.
Under the great support of the Natural Science Foundation Committee and the National 863 Planning Committee, study on the ecological environment materials in China has achieved grown progress and development and we have done a lot of solid work in terms of LCA of typical materials, photocatalytic degradation materials, recycling and reuse of metallurgy residue, completely biodegradable materials and wooden ceramics, etc., and we have achieved plentiful and substantial achievements in certain aspects.
So far, there have been a lot of reports about application of LCA in material science and engineering and about the entire life process of LCA method in assessing a certain material product or its technical process.
Research on LCA of the entire life cycle or a certain phase of the life of materials and their products as well as the production, usage and abandoning of the materials and their products is the fundamental job to modify and even eliminate the materials, their products or the production technique.

Introduction With the rapid development of materials science in the 21st century, many materials are effectively applied to the research on life sciences.
And the research on life sciences also can not develop well without the development and application of materials.New materials are not only the significant parts of modern high science and technology but also the important pillars and breakthroughs of developing high and new advanced technology.
(Composite materials with hydroxyapatite and epoxide-acrylate-maleic anhydride is abbreviated by EH composite materials.)
Prospect.In recent years,with the rapid development of materials science,the research on nano materials and nano technology has become a new field which attracts many scientists.Nanometer materials with the characteristics including interface effect, small dimension effect and quantum dimension effect may form a stronger biological bonding between the structures replaced and bone tissue.If nano biological materials are used to make aritificial ossicle structures, an excellent biocompatibility,superior performance and long-term post-operative stability will be likely to be brought to aritificial ossicles ,which will serve human beings better.
