During heating phase, the material of heating bridge expands, leading the actuator turns to the unheated bridge.
While cooling, the material contracts and the actuator turns to the heated bridge at the end.

Introduction Ion-exchange materials have long been widely used in pharmacy and medicine[1-3,5,8-11].
Fibrous ion-exchange materials are suggested to have a larger surface area to unit volume ratio, which leads to a higher absorption rate and absorption capacity as compared with the resin [12].
Materials and Methods Materials.Strong acid ion-exchange fibers [ -SO3H ion exchange groups, poly (ethylene-g-styrene-sulphonic-sodium) were obtained from Guilin Zhenghan Co.

Evaluation of Electrochemical Behaviour and Surface Properties for Oxinium-like Zr-Nb Biomedical Alloys Ioan-Viorel Branzoi 1, Mihai Iordoc2,* , Florina Branzoi3 1 POLITEHNICA University of Bucharest, Faculty of Applied Chemistry and Materials Science, Department of Applied Physical Chemistry and Electrochemistry, 132 Calea Griviţei, 010737 - Bucharest, Romania 2 National Institute for Research and Development in Electrical Engineering, INCDIE ICPEAdvanced Researches, 313 Splaiul Unirii, 030138, Bucharest-3, Romania 3 Institute of Physical Chemistry, Spl Independentei 202, Bucharest, Romania Contact details: mihai_iordoc@icpe-ca.ro Abstract The aim of this study is to evaluate the influence of Nb amount on electrochemical behaviour and surface properties for Oxinium-like Zr-Nb biomedical alloys.
The advantage is that the surface of the metal can be transformed into a relatively thick (micrometers) zirconium oxide (i.e., zirconia) ceramic-like material, thus combining the benefits of ceramic and metal in one component [7].
Vickers hardness is a measure of the hardness of a material, calculated from the size of an impression produced under load by a pyramid-shaped diamond indenter.

Introduction Ultra High Molecular Weight Polyethylene (UHMWPE) is polymer materials of high strength, high wear resistance and low friction coefficient.
But because UHMWPE’ surface is inert and non-polar and at the same time highly oriented and crystalline, UHMWPE’ surface wetting is poor and has the very poor bonding properties with other materials. 45# steel has high surface energy and good adhesive properties.
Because the surface properties of UHMWPE is very different with 45# steel, how to bond the two materials is a quite difficult problem.
Experiment Materials Chloroprene rubber A-90 (CR) was provided by Japan NEC Chemistry.
