Nanocoatings for corrosion protection of aerospace alloys

Nanotechnology Emerging Trends, Markets, and Concerns

“…However, the most important indicators are the number of scientific articles and patents recently published in those fields. The number of scientific articles is a good indicator of scientific activity; the number of patents shows the transformation of the scientific results into different technologies, applications, and markets [12][13][14][15][16][17][18]. The data in the Science Citation Index (SCI) database shows that between 1981 and 1985, the number of publications related to nanotechnologies is not significant, but it confirms an inclining trend after that date [12].…”

“…The following recommendations are outlined to assess and control workplace exposure [18][19][20][21].…”

“…A comprehensive research effort is needed, along with the continual reassessment of the available data to find out whether medical screening is necessary for workers exposed to engineered nanomaterials [18][19][20]. The following recommendations are necessary in regard to workers exposed to engineered nanomaterials:…”

Nanotechnology Safety in the Energy Industry

“…Of the many parts of a wind turbine, the blades, mostly made of glass fiber-reinforced composites, are of utmost importance. All these developments accelerate the aging process, produce fatigue cracks, and reduce the overall mechanical properties and lifetime of the composite blades [17]. Research into the use of carbon fiber composites is underway because they are light in weight and are stronger than many of their counterparts.…”

“…A typical blade diameter for a 2.5 MW turbine is about 100 m. As the capacity of the turbine increases, the length of the blade also increases, and thus the need for lighter and stronger turbine blades [15]. Figure 10.6 shows the atmospheric influences on organic coatings and corrosion formations on substrate coated with an epoxy-based polymeric substance [16,17]. Additionally, environmental factors, such as UV light, oxygen, pollutants, and moisture, are introduced into the polymeric composite blades during the time that the blades are in service and result in breakage of the carbon-hydrogen chemical bonds, formation of oxide species, and internal and external stresses [16].…”
