Introduction Magnetite (Fe3O4) and maghemite nanoparticles have attracted increasing attention as promising candidate materials for clinical applications such as drug delivery system, magnetic resonance imaging reagent, cell separation and labeling, and AC magnetic field-assisted cancer therapy [1-3].
The proposed material transformation in a reverse micelle is shown in Scheme 1.

Mechanics theory of vacuum chamber Acorrding to actual working condition of vacuum electron beam welding machine, the selected material of chamber is low carbon steel.
Therefore,in the actual production,we not only waste a lot of material, and can't easily control the deformation of vacuum chamber.
Looking up the related manual about mechanical design,we can get material property parameters.
Through this optimization, the thickness of vacuum chamber reduce by 2mm,and save about one ton materials.Besides,the deformation changes from 2.278mm to 1.452mm.

The three-dimensional influences around the interfacial crack tip are not caused only by the existence of the crack per se, but they also depend on presence of the material mismatch along the interface.
The Problem Formulation The stress field the around the tip of a crack at the interface between the two different materials is a linear combination of the types of fields, the coupled oscillatory field, which is defined by the complex stress intensity factorand the non-oscillatory field, which is measured by the real stress intensity factor KIII.
Parameter e is called the oscillatory index, it is a characteristics of the interface crack and is determined as, [2]: , , (2) where b is one of the two Dundurs' parameters, [3], where mi is the shear modulus, ni is the Poisson's ratio, subscripts i = 1, 2 refer to material above and below the interface, respectively, while is valid for the plane strain state and is valid for the plane stress state.
From Fig. 4 is also visible that the extension of the 3D zone at the lower material side is significantly smaller, which is due to the fact that it has very small deformation. 4.

Introduction DIC technique could be used to assess the deformation of any structure, materials in point and the localized deformation is measured by processing two high quality digital cameras.
A detailed design and fabrication of test rig, LMMB set, material selection and their application are discussed in [3, 4].
From the Figure it is also revealed that the raceway relative approach values was slightly fluctuating initially for the following reasons: 1) LMMB raceway tolerance and flatness (geometry), 2) Improper heat treatment followed by its material properties, 3) Bearing ball tolerance and, 4) Non standardization of hardening on material.

Introduction In this paper according to the material properties of structural steel and concrete under high temperature, the bonding strength changing laws with different temperature and its formula of the profiled steel sheet-concrete are deduced, and obtained the bonding stress-slip relationship, so as to established a nonlinear finite element method of analyzing the steel concrete composite slab fire properties.
Temperature distribution is unrelated to stress levels , whereby the temperature analysis will not consider the influence which component deformation, cracking, stress and strain level and other factors impact on the thermal parameters of materials and components thermal conduction. 4.
Material stress-strain line is a nonlinear elastic relationship.
