Plant structure bionics is based on the principles of engineering mechanics.
With inspiration from the forms and functions of plants at different levels (micro, meso and macro), the materials, structures and systems of plants are imitated to improve efficiency of engineering structures [2].
Structural bionics involves multi-disciplines, such as botany, plant physiology, soil science, optics, biophysics, biochemistry, physics, electronics, ergonomics, psychology, materials science, mechanics, dynamics, control theory, engineering, economics, color, aesthetics, communication, ethics and social science.
To improve integrated performance of intelligent building materials, and expand their engineering applications have become key steps to further develop intelligent building materials.

Using Chemiluminescence to Study the Photodegradation of Materials Keith R Millington1,a, Michael J Jones1,b, Siti Farhana Zakaria2,c and George Maurdev 1,d 1 CSIRO Materials Science and Engineering, Belmont, VIC 3216, Australia. 2 School of Fashion and Textiles, RMIT University, Brunswick, VIC 3056, Australia.
Chemiluminescence (CL) is a straightforward method for studying the free radical degradation of organic and biological materials.
Introduction Photodegradation of organic materials exposed to sunlight in Earth's atmosphere normally occurs via free radical autoxidation [1].
Emission of PICL from organic materials is dependent on the presence of oxygen.

In order to solve technological key problem of metallic rubber in the respect of engineering application, based on porous materials theory, this paper explored the method of nonlinear constitutive relationship constructed, thus in view of the effect of heat treatment technology on nonlinear constitutive relationship of metallic rubber, static experiments are made for seven kinds of tempered metallic rubber and seven kinds of untempered metallic rubber, it was found that each coefficient of nonlinear constitutive relationship of tempered metallic rubber was bigger than that of untempered metallic rubber, and the deformation of tempered metallic rubber was smaller than that of untempered metallic rubber.
Such a material combines the rubber-like elasticity with porosity, and, in this regard, it differs from all other materials.
In the field of engineering, we wish to achieve appropriate metallic rubber structure effectively and quickly, but there is great distance between theoretical description and practical engineering, and the distance is a key technique problem affecting metallic rubber structure used widely.
In order to solve the problem, based on porous materials theory, the method constructing constitutive relationship of metallic rubber is studied.
The research fruit has an important significance for engineering application of metallic rubber and manufacturing quickly isolator made of the material.

Some key problems of development in FCEV DC/DC converter are particularly analyzed, including of reliability, efficiency, static and dynamic characteristic, etc.
High Power DC/DC converter is one of the essential key devices in most developing FECV at present, due to the soft electrical output characteristics and the consideration of control system of the vehicles.
The characteristics, such as high power (from dozens kW to hundreds kW), high efficiency (more than 96%), security and reliable and small in size, are required by the DC/DC converter in fuel cell electrical bus, therefore, the study of high power and high efficient is of important theoretical significance and engineering application value to the development of FCEV[1].
FCEV is one of the main directions of future advanced vehicle, and the breakthrough of key technology used by DC/DC converter in FCEV will boost the research and development of FCEV.

The materials used in high-temperature structures have design constraints which are in addition to those on materials used at, or near to, room temperature.
The addition of these constraints to those of low cost, strength, toughness, machinability, formability, weldability, and combinations of these, has led to the intensive development, over the past 50 years, of an extensive group of metallic materials: generally referred to as "high-temperature alloys".
The purpose of the present book is to provide chemical, metallurgical and materials scientists and engineers with up-to-date corrosion data pertinent to academic studies and industrial problems resulting from the effects of pure molten salt and ash/salt deposit environments. 
The book covers key aspects of corrosion reactions in molten deposits, and provides a wealth of engineering data to help in making a shortlist of candidate materials for high-temperature service under such conditions.
