Introduction The studies of silica particles nucleation and growth by sol-gel method started in the 1800s, noting that the hydrolysis of tetraethylorthosilicate (TEOS) in an acidic medium resulted in glass structure materials [1].
Materials and Methods The samples were divided into groups, varying the molar ratio of water/TEOS in 25 and 155, the reagent feed rate was varied in 0.6 ml/min and 18 ml/min and pH in 9 and 12.

It can be widely applied in all kinds of motor vehicle suspension damping system. 1 Overview of magnetic fluid elastomer Magnetorheological materials is a theological properties can be made of magnetic field of new intelligent materials control, because of its fast response (ms middleweight), reversible good (remove magnetic field, and recovery after the initial state), and by adjusting the magnetic field size to control the mechanical properties of the continuous changes, and in recent years in the automobile, building, vibration control and other areas to be widely applied.
Because it with the magnetic fluid materials and the advantages of elastomer, and overcome the magnetorheological fluid settlement, poor stability of faults, and so that it become the magnetic fluid material a hot issue[2, 3] in recent years. 2 NR/SBR and rubber base magnetic susceptibility of rubber preparation A. the main raw material (1) magnetic filling particles, (2) coupling agent B. magnetic susceptibility of rubber material preparation In the paper, the most ordinary rubber common preparation methods: mechanical blending method.

Introduction NiMnGa single crystals of ferromagnetic Heusler alloys are promising materials with thermoelastic martensitic transformations (MT), which have unique properties such as shape memory effect (SME) and superelasticity (SE).
However, NiMnGa single crystals are brittle and investigations of Heusler alloys are focused on researching new materials with greater plasticity or the improvement of the plasticity of NiMnGa single crystals by thermal or thermomechanical treatments.

Gear surface wear is a direct material loss phenomenon and it has great effect on the vibration and noise traits of the gear system.
But in the engineering practice, the surface wear induces direct material loss of gear teeth and the accumulated wear on each tooth is not equal to each other.
