Preparation and Characterization of Silane Modified Fe3O4 Nanoparticles by Reverse Micro-emulsion Ying Yao, Yingying Shen, Xueyan Du State Key Laboratory of Gansu Advanced Non-ferrous Metal Materials, Lanzhou University of Technology, Lanzhou 730050, China email: xueydu@hotmail.com Keywords: Fe3O4 NPs; Silane coupling agent; Modified Fe3O4 NPs; Reverse micro-emulsion Abstract.
Generally, the saturation magnetization of the materials is not only related to the preparation conditions, but also related to the thickness of the coated layer.
The decrease of saturation magnetization could imply to a certain extent that KH-570 was coated on the surface of Fe3O4 NPs.This unexpected decrease of magnetism by an organic capping layer has strong implications for the optimization of a wide family of materials.

As the anti-impacting and energy absorption material, the aluminum foam is always used for making the sandwich plate which the aluminum foam as the core material, and the plate is usually made by metal or composite material which can enhance stiffness of the sandwich structure.
Experiment Results and Analysis The sandwich plate core material-aluminum foam is rate-dependent material, so the SHPB was adopted to test the aluminum dynamic mechanical properties, the results as shown in Fig.10, Form the Fig.10 we can see that the materials deformation is basically same with static sandwich plate compression experiment and also has "three stage", and the dynamic yield stress is nearly two times higher than the static experiment, and strain rate phenomenon is very obvious.

Introduction Because of the high specific stiffness and strength, as well as the outstanding fatigue performance and high chemical resistance, FRPs are becoming one of the most important lightweight materials and have become irreplaceable nowadays.
The fiber reinforced composite manufactured based on thermoplastic materials (FRTP) have several advantages over those based on thermosetting plastic materials (FRP), including improved toughness and better recyclability as well as the possibility of a rapid processing cycle[1].
Experimental Materials.
The feasibility of the proposed method was confirmed, and its application is promising in the manufacture of carbon- or glass-fiber-reinforced thermoplastics when the reinforcing materials are in the form of fabric.

Intorduction Ferroelectric lithium niobate monocrystal is one of the most important and popular photorefractive nonlinear optical materials. [1, 2].
However it contains microregions, clusters, and other spatial defects that significantly impair the quality of optical materials.

A solution was found in the materials recyclability process.
RAP can be recycled and incorporated in different types of mixes like Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA) or Cold Mix Asphalt (CMA) or as aggregate in granular or stabilized base materials [4] together with “virgin” materials.
When a road pavement reaches the end of its service life, the materials can still maintain considerable value.
Austria does not confront the crisis as bad as Spain and they still have high quality ”virgin” materials.
Cost analysis suggests significant savings due to the use of RAP mixes, resulting from savings in materials and energy costs.

For an initially flat homogeneous CB, the amplitude Y(x,t) of the lateral deformation is the solution of the Bernoulli-Euler equation: (1) where E is Young’s modulus, I is the area moment of inertia of the CB cross section, r is the density of the material and S is the cross-sectional area of the cantilever.
