It is well known that metal complexes can cleave proteins with a high specificity under specific conditions, and will be useful for structure-activity studies of proteins, elucidating the solution structure of proteins, and cleave proteins into smaller fragments are more beneficial for sequencing[2-4].
To design artificial proteases is an important subject in the area of bio-related chemistry in view of the importance of proteins in modern biology.

Introduction Surfactant templated materials have played an important role in materials chemistry since the discovery in 1992 of hexagonally-ordered mesoporous silicate structures by Mobil Corporation (M41S materials) [1].
In 2002, Inagaki and co-workers [3] reported the synthesis of a material containing benzene linked to two silicon atoms, in a hierarchically-ordered structure with meso- and molecular-scale periodicity.
The figure clearly shows the effect of the surface chemistry of the solid.

The structure of prepared hydrogels was confirmed by Fourier Transform Infrared Spectroscopy.
This focuses on the relationship between hydrogel structures and their properties.
The structure of the prepared IPN hydrogel is shown in Fig. 1.

Hence, the X-ray luminescence intensity depends more on the perfection of the matrix crystal structure than on the content of luminescence centers in the phosphor.
The highest X-ray luminescence is observed for the phosphors featuring with the largest particle size and the highest perfection of the matrix crystal structure.

Different thermal coefficient may be attributed to different specific area and structure of five kinds of carbon black.
The higher the structure of carbon black is, the easier carbon black aggregation joined to each other is, so thermal conductivity net comes into being easier.
Thermal coefficient of N375 was larger than of N330 for the structure of N375 was higher than of N330.
Specific area and structure of carbon black were found to be very important factors affecting thermal conductivity, the larger specific area was and the higher structure was, the better thermal conductivity was, and reuniting phenomenon of nano-level carbon black also had an influence on thermal conductivity.
