For the mechanical erosion, ductile materials and brittle materials show different erosion properties.
The erosion rate of ductile materials is peaked at a low incidence angle, while that of brittle materials is peaked at normal incidence.

Introduction Nanotechnology is the use of very small particles of material to create new large scale materials.
Obviously, Concrete is one of the major construction materials.
Addition of nanoscale materials into cement could improve its performance.
These are in the development of improved materials and the use of characterization methods to improve the understanding of materials.
Indeed, in the field of pavement, nanoscale materials can be applied to the surface of existing materials to improve aspects such as their hardness, durability, skid resistance and water resistance constitutes potential applications.

This is an area where technologists, biologists and physicians work together to gain basic knowledge of the physical properties and behaviour of biological materials.
Advances in biomedical technology made possible by this partnership include dialysis machines designed to replace sick and malfunctioning kidneys; hip and knee prostheses; materials and technologies for the work of the heart and blood vessels; artificial heart.
For example, biomimetics is a branch of bioengineering that seeks to use structures and functions of living organisms as models for the design and manufacture of machines and materials.

In this study, the stabilization/solidification of lead in soils using alkali-activated cementing materials with rich-silicon materials was investigated.
Experimental Materials The blast-furnace slag was originated from Wuhan Iron and Steel (Group) Company.
The chemical components of the five materials were shown in table 1.
On the other side, the hydration of the binders including rich-silicon materials produced C-S-H which had large specific area.

The objective of this paper is to apply the wood-based composite materials into the field of intelligent decorative materials or wooden crafts materials, and then improve people's life quality in the micro-environment.
With the development of science technology, people come up with higher and higher demands on materials utilization.
The traditional structural materials and functional materials can not meet the requirements of these technologies.
The development of materials science is turning from the traditional and single, only having the carrying capacity of structural materials or functional materials to the multi-functional, intelligent, structural materials.

Introduction In recent years, with the continuous development of science and technology, the research and development of new materials become more and more comprehensive, and gradually develop and promote some polymer materials [1].
However, most of these polymer materials are brittle materials, which often have defects in the preparation process.
