The nature of VE is very unstable, when exposed to the air, the phenolic hydroxyl group of VE structure is oxidized susceptibly and has no longer biological activity.
The effective way is to wrap up the sensitive part of VE molecule so as to keep it from contacting with air, for example, microencapsulation [2], transforming it into its derivatives by modifying its structure such as VE acetate [3] and VE linoleate [4].
Prepolymerization of Polyurethane Influence of isocyanate structure on reaction activity is reflected in two aspects: inductive effect and steric effect. 2,4-TDI is an aromatic diisocyanate that includes two NCO groups, ortho- and para-NCO, which have an inducement with each other to make reaction activity of the isocyanate increase.

As the vertex angles of silicon-oxygen tetrahedron of six-membered ring in tourmaline structure point to the same direction, it would make tourmaline have great hetero-grade symmetrical structure and so produce spontaneous polarization similar to that of magnet pole, which apparently appears as piezoelectricity and thermoelectricity.

It was established that the morphology of the PI/titania hybrid can be controlled by introducing titania structure onto main and side chain of PI molecule,[5-6]The adding coupling agents KH550 were concentrated on improving the interfacial interaction between organic and inorganic components to make titania inorganic particles disperse in PI matrix.
The diffuse interface layer could probably be fitted with the following equation: E=(2π)0.5s , where s is negative slope of hybrid films, E is the average thickness of the interface layer which is a characteristic structure parameter in relation to the physical and chemical properties of materials.
The micro morphology, structure, and electrical and mechanical properties of PI/TiO2 nanocomposite films were studied.

Introduction Implant materials are being increasingly designed to provide optimal pore structure for osteointegration, and a subsequent increase in the bone to implant bond [1].
It results in a stoichiometric, homogeneous and pure coating due to mixing on the molecular scale; reduced firing temperatures due to small particle sizes with high surface areas; it has the ability to produce uniform fine-grained structures; the use of different chemical routes (alkoxide or aqueousbased); and their ease of application to complex shapes with a range of coating techniques: dip, spin, and spray coating.
Results and Discussion FTIR studies showed that HAp coatings were pure carbonated hydroxyapatite with a nanocrystalline structure.

However, Mg alloys have difficulty in cold-workability because of their crystal structure.
In order to improve the workability of Mg alloys, bcc-structured Mg-Li alloys were developed.
In addition to its lightweight, Mg-Li alloys are more susceptible to corrosion than hcp-structured Mg alloys.
