Among these olivine cathode materials, the pristine LiNiPO4 shows high voltage vs Lithium while exhibiting extremely poor electronic conductivity at ambient temperature [2].
Such kind of morphology is very important to achieve high capacity and good cycleability of the cathode materials.

Introduction
Nano crystalline materials have received considerable interest for their improved physical, chemical and mechanical properties [1].
Many of these applications require a good understanding of corrosion behavior of the materials as a function of microstructure.
Some researchers have been shown that nanostructure materials have worse corrosion resistance [5,6] and some others have shown better resistance in comparison to coarse grained materials [7-9].

When inelastic material behavior has to be considered, additional effort has to be spent onto
tracking the history of the material particles within the spatially fixed finite element mesh.
The transport of the material points within the spatial mesh is modeled in a second step, where the advection of history dependent material variables is performed.
It only describes first order effects of the rather complex behavior of rubber like materials.

Abstract.
Miles in GM developed the scientific theory in practice, which reduce product costs by using material substitution on the premise of product function, to solve the shortage of resources after world war TWO.
With the social development of material civilization and spiritual civilization, people have higher expectations and more demands of consumer products.

Intensified internal leakages in the hydraulic cylinder, effected by leakages at the piston, can result from what follows: ageing of seal materials; contamination of the working fluid; parameters of the working fluid inconsistent with the system specifications, faults in the production technology.
Major causes of the hydraulic-circuit leaks are as follows: fatigue cracking of hydraulic pipes, tubes, hoses; leakages at hydraulic-line joints (improper hydraulic pipe-end extensions, excessive or too low assembly stress in pipe joints); faulty manufacturing of conduits (material faults, improper technology of conduit bending), mechanical damages to conduits (effects of faulty assembly of other structural components of an aircraft); others.

Introduction
Since 0.2% MFIS was firstly found in Ni2MnGa single crystal in 1996 [1], Ni–Mn–Ga ferromagnetic shape memory alloys (FSMAs) have received more and more attention as potential magnetic actuator and sensor materials due to their large magnetic field induction strain (MFIS ) and high response frequency [2–4].
As is well known, the chemical composition of material significantly affects the Curie temperatures of Heusler-type Ni–Mn–Ga ferromagnetic shape memory alloy.
