Natural organic acid leaching technology has the characteristics of non-toxic, environmentally friendly, not undermining soil structure, easy to degradation and other advantages.
Microorganisms can fix, mobile or transform heavy metals in soils, changing their environmental chemistry behavior, detoxifying or reducing the toxicity of toxic and harmful substances, so as to achieve the purpose of bioremediation [10, 11].

During the pipeline steel SCC process, the interaction between mechanical and chemistry happened in the area of stress concentration at crack tip leads to environmental sensitive crack.
Fig.1 shows the microscopic structure of X70 pipeline steel.

Furthermore, the shape-dependent photoluminescence makes it clear that chemical synthesis of nanoparticles with well-controlled shapes, structures and sizes is both scientifically and technically important.

C3H6O2 and C6H15N were purchased from Sigma-Aldrich Chemistry and used as chemical agents of surface modification of TiO2 nanoparticles.
The modified TiO2 played an important role in improving tensile properties of the nanocomposites due to its unique structure and the reasonable interfacial interaction between the nanoparticles and PBS matrix.

Dielectric tunability of Mn doped Pb0.3Sr0.7TiO3 multilayered thin films prepared by sol-gel method Xiaohua Sun1, 2a, Shenggang Zhou1, Zhimeng Luo1, Shuang Hou1, Tianyou Peng2, Xing-zhong Zhao2 1 College of Mechanical and Materials Engineering, China Three Gorges University, China. 2 School of Physics, College of Chemistry and Molecular Science, Wuhan University, China.
Our results showed that multilayer structure can improve the comprehensive dielectric tunable performance of PST film.
In order to optimize the dielectric properties of PST thin films, many efforts have been devoted to fabricate multilayer structure films.
The crystal structures of undoped and 4.5 mol % Mn-doped PST powders are cubic phase and no second phase appear, which implies that the dopants have entered the unit-cell maintaining the perovskite structure of the solid solution.
Our results showed that multilayer structure can improve the comprehensive dielectric and tunable performance of PST film.

This paper also review on development in device structure to get desired higher output in OSC.
With respect to understanding the chemistry, physics, and materials science of organic materials, work and research remains to be done to further improve their performance.
The early work in device structure by tang, it is stated that the offset bandgap between high occupied molecular orbital (HOMO) and lowest occupied molecular orbital (LUMO) of the polymer allowed exciton dissociation more efficient in the heterojunction structure interfaces.
