Introduction One of the tasks of Physics of nanomaterials is development of new magnetic materials with targeted properties.
Moreover, the formal description allows modeling of magnetic properties of nanoparticles with any type of ordering: whether they are ferromagnetic, antiferromagnetic or ferrimagnetic materials.

Introduction The newly developed homogenization theory of masonry allows the global behaviour of masonry to be derived from the representative volume element with consideration of mechanical characters and mixing effect of the materials[1].
Assumptions of homogenization model Fundamental assumptions of homogenization model(Fig.1):(1) include all the participant materials;(2) constitute the entire structure by periodic and continuous distribution;(3)The representative volume element provides a valuable dividing boundary between the discrete model and the continuum model;(4) Brick and mortar are elastic-brittle, that is to say yield criteria is the failure criteria.
Fig.1 Homogenization of Masonry Material Strength Conception of Masonry Homogenization Model Elastic Constitutive Relationship of Representative Volume Element(RVE) On the supposition that direction of principal stress and material principal direction are same, The stress-strain relationship of representative volume element is shown as follows: (1) meanwhile: ， (2) Regarded representative volume element as plane orthotropic materials, form elastic mechanics of anisotropic body, the following equation is validity to give an approximate value ；and where (3) and (4) Elastic modulus and poisson ratio can be obtained by the following specific displacement border conditions

Enormous growth in material science have evolved few more materials to be used in MEMS which follows the basic requirements, these materials are metals like Ni, Al, nonmetals like Si, Ge, GaAs, polymers like SU8, polymide like diamond, SiC, Si3N4 ,SiO2 [7].
Mathematical Modeling By consideration of Mason’s analysis [8], the equation of motion of membrane under tension can be expressed by, (1) is the thickness of the membrane, is the value of poison’s ratio (ratio of lateral concentration to the longitudinal expansion of material) , ω is displacement normal to the plane of the membrane, is the tension on membrane, is the transverse pressure on the membrane and is density of the material.
Now, the particular integral So, the particular integral (5) The general solution of the above equation will be, (6) Now ‘w’ will be maximum at r = 0 then multiply by ‘r’ in both sides we get, And will be zero at r = a so, (7) (8) And if we assume, then Where, = dielectric constant of material between the plate and=electrode spacing So, (9) Results and Discussion The different parameters value are selected from the fabrication technique used [6] shown in Table 1.

LiFePO4 battery charge and discharge and its working principles There are many materials of the LiFePO4 battery’s cathode, mainly lithium cobalt oxide, lithium manganese oxide, nickel oxide, lithium ternary materials, such as LiFePO4.
From the material principle, that refers to the LiFePO4 used as cathode material for LiFePO4 batteries.
Additives in subsequent reactions that can play a role in reducing, but also the formation of LiFePO4 particles coated effect can greatly improved the conductivity of cathode materials[4].
Conclusions LiFePO4 battery performance depends primarily on the positive and negative materials, its safety performance and cycle life are unmatched by other materials.
