The so-called nanometer materials have the size within l - 100nm in thickness, which originates from the 1980s. At that time, nanometer materials didn＇t have a proper development due to the economic level. t towever, with the support of science and technology, this technology has undergone tremendous changes in the related fields. There have been increasing expansion in the kinds and the width in use of the nanometer materials, so have the research of nanometer materials. In this paper, we will briefly analyze the application ofnanometer materials in the sports engineering.展开更多

It aims to make mud bricks lightened with good mechanical, thermal and sound properties and enhance the waste polystyrene. This article is the result of experimental work on a broad field of applied sciences： building mechanics. The study is focused on BTS （blocks of stabilized earth） chosen as reference materials to which we linked polystyrene. The percentage of polystyrene varies from 0% to 100% starting from a constant volume of each reference material. The results showed that the increase in polystyrene percentage lowers mechanical properties. These results also showed that the gradual addition of polystyrene to the laterite-cement mixture has a significant influence on the density and mechanical resistances of the final composite material.展开更多

The aim of this article is to analyze the various strategies for stabilizing human knowledge, with a special focus on its material anchors and their interactions with other stabilization means. In particular, I consider how such stabilization is reflected in scientific activity and practice, and what its repercussions are for the models of science that have dominated the philosophical landscape of the 20th century. My starting hypothesis will be that the role of material anchors in stabilizing conceptual blends is analogous to that of technology in grounding scientific knowledge. The framework I adopt with regard to conceptualization is that of Fauconnier and Turner （2002） on conceptual blends. Just as technology intervenes in scientific practice in conjunction with conceptual elements, so do material anchors, which conjoin other non-material strategies of knowledge stabilization. Endowing knowledge with a material basis may be understood firstly as an element （sometimes a key element） for representing knowledge and offering an explanation, and secondly as a way of providing a scientific hypothesis with empirical grounding. It is this second sense that connects with scientific experimentation and the use of instruments and technology.展开更多

But, today＇ s modern craftwork art is not completed by hands and simple tools and doesn＇ t depend on the limited natural materials to cope with today＇ s human life needs, but it must be equipped with the beauty wisdom, industrial science and technology, economic ideas and production and manufacturing technology, so that it can produce the modern craftworks full of the era significance. This paper first analyzes the charm of modern craftwork art design, and then explains how to use the modern craftwork art design, which has a certain practical value and reference significance.展开更多

Because the visible light-curable(VLC) system causes no biological damage, it is popular as a dental material and is being investigated by many researchers for other medical applications. Here, the principle of the VLC system is explained and recent progress in key components including photoinitiators, monomers, macromers, and prepolymers is discussed. Finally, biomedical applications for drug delivery and soft tissue engineering are reviewed. Considering the recent development of VLC systems, its importance in the field of medical applications is expected to continue to increase in the future.展开更多
