Materials based on mixed ferrocyanides can be alternative and more promising sorption systems [1].
Materials and Methods To extract Cs-137 from seawater, composite materials based on mixed ferrocyanide Ni-K and Zn-K are synthesized in a composition with a siloxane-acrylate emulsion and polyethylene.
Results and Discussions According to the X-ray diffraction pattern of sorption materials based on mixed ferrocyanides (Fig. 1), the obtained materials have a highly organized crystal structure, as evidenced by the presence of peaks in the X-ray diffraction patterns of the analysed materials.
The phase composition of materials based on mixed ferrocyanides Ni-K and Zn-K is shown in the corresponding figures.

This paper describes an approach to identify the influence of mechanical properties of the materials under the condition of containing residual stress.
By comparing the original specimen with the specimen contains residual stress, the change of the mechanical properties of the materials can be studied.

Three different types of motion between the journal and bearing can be observed during the dynamics of the revolute joint clearance, namely, (1) free flight mode, in which the journal moves freely within the bearings boundaries, that is, the journal and the bearing joint are not in contact; (2) impact mode, which occurs at the termination of the free flight mode, being impact forces applied to and removed from the system; (3) permanent contact, in which contact is always maintained although the relative penetration depth between the bearing and journal varies along the circumference of the journal [5].
The journal radius of crosshead pin is 35 mm while the initial bearing radius of connecting rod is 35.1 mm.
The materials in contact have the properties of steel with Young’s modulus 2.06×1011 N/m2, Poisson’s ratio 0.3 and zero friction is assumed.
Fig. 5a depicts the journal center path of the joint with clearance.

The course is conducted together with the professional basic course, such as "physical performance of inorganic material", "introduction to environment science", "introduction to energy science" and "introduction to inorganic non-metallic materials".
Besides, the course interpenetrates with the specialized courses such as "new power material" and "environmental materials science".
One of the students preached his thesis in the "2nd International Conference on Energy and Environment Materials" held in Guangzhou in December 2004, which was published in the Journal of Zhongshan University (Natural Sciences).
