Deposition of thin layer of various semiconducting materials such as TiO2, Nb2O5, ZnO and SnO2 on lucid glass plate of FTO or ITO are used to make the working electrode.
The performance of DSSC depends on the propensity of attachment of these natural pigments to the semiconducting materials of working electrode.

Introduction A Dislocation and dipole are the common line defect in crystal materials.
The interaction of other defects in materials, such as cracks, holes, rigid lines, and so on, with dislocations and inhomogeneities is important for researching the strengthening and toughening mechanism and damage effect of materials.
The two materials are assumed to be perfectly bonded along the interface.

When machining aerospace monolithic components, most of materials could be removed, resulting in severe deformation of the parts due to the release and redistribution of the blank's original residual stress, together with the action of cutting loads and clamping force.
In the milling process, more than 90% of the materials would be removed which results in its low rigidity.
Computer Simulation The Physical Dimension and Material Properties of the Part.
The removal of the materials is realized by element birth and death technology.
