        摘要：Bio-minerals are generally composed of 95% inorganic salts and 5% organic matrix. Compared to natural minerals, bio-minerals have superior mechanical properties, beautiful colors, special bio-functions, and so on. All of the above characteristics originate from the precise controlling-effects of cells and bioactive macromolecules on the crystallization behavior and minerals morphologies. This review introduces the research progress on the effect of chitin and chitosan on the mineralization process of bio-minerals and bio-mimic materials.

        摘要：Surfaces are the phase boundaries that reside between the materials and the outer environment. Application performance for a material relies largely upon the surface properties in many cases.Grafting different polymer chains onto the material surface can satisfy a wide variety of requirements.Being a very promising method, surface-initiated living (controlled)polymerization offers the advantages of uniform grafting chains, well defined chain structure, and controlled chain length.This review covers the recent studies on the living (controlled)polymerization from different surfaces by various mechanisms.

        摘要：Zeolites are crystalline aluminosilicates with a framework structure based on the three-dimensional arrangement of TO4 (T = Al, Si, P, B, Ga, Be, etc) . Molecular sieves play both the role of supports of catalysts and nanoreactor for the olefin polymerization to proceed. The olefin polymerization process is more controllable due to the immobilization and the resulting polyolefin exhibits adjustable molecular weights, polydispersity index, rheology, stereoregularity, comonomer content, and improved morphology. A review focused on the research and development of olefin polymerization with catalysts immobilized onto molecular sieves is presented herein.

        摘要：This paper introduced the principle of microwave irradiation on starch briefly.It is generalized that the investigation progress at home and abroad about the effect of microwave radiation on morphological structure and crystalline structure and gel property and thermal property of the starch.For example, the microwave radiation could change the morphologic structure, the crystal structure and the crystallinity of starch.The parameters of the microwave irradiation, such as irradiation time and wave power etc, could change the gel properties of starch. Solubility, swelling ability and water absorption of starch were lower than that of the native starch.

        摘要：Copolymer average composition curve of Polymer chemistry is designed by use of the multimedia producer VC+ + 6.0.Curve showing window is made up of such six functions as an re-drawing coordinate system, cancelling the current curve, cancelling all the curve, drawing new curve, input parameters, exit window. Control technologies make it come true to type in parameters, draw curve, draw color curve and coordinate system, re-establish the line and its thickness, show sequent curve, and many other related parameters and so on. It can serve as not only an efficient tool for polymer chemistry teachers to teach in class, but also a helpful approach for students to do exercises. It is a useful supplementary computer teaching software with advantages of convenience, simplicity and high efficiency.
