They are responsible for the onset or escalation of corrosion caused by previously existing detrimental specialists such as water and carbon dioxide. However, only a few reports on their real success against MIC have been published. Numerous studies on stainless steel, in the presence of microorganisms, are discussed. An analysis of microbiological contamination is also detailed. It focuses on the general perspectives of the various microscopic species involved in biocorrosion.

The findings and results from the review prove that the AI control technique is a promising one in the future for uncertain dynamic systems. The paper also covers a review of the vinyl chloride monomer (VCM) process and a recent control study on the plant. Being a nonlinear system, VCM requires advanced control techniques to control the uncertain dynamics of the process. The study shows a gap in the development of control strategies applied to VCM in terms of sustainability, efficiency, and environment-concerned issues.

Using 93 references listed in this review, the relationship between metal dopant and synthesis methods to the efficiency of ZnO and composite ZnO-metal in degrading pollutants for photocatalyst applications is studied. The basic principles of the photocatalyst process is described when the electrons at the valence band of ZnO get the energy from solar spectrum, generate the charge (electron and hole), and then continue to react with superoxide and water, resulting in radical atoms which break the bonds of organic pollutants. Rare earth dopants have the highest efficiency up to 100 % at 15 min irradiation. Conclusions and future prospects of ZnO and metal-doped ZnO are also discussed.
