Applications of Nanotechnology In Industries
The most abundantly used material in the industries is the steel. Because of amazing properties such as tensile strength, shear strength, resistance to corrosion steel took over iron in the industries long back. There are so many ways in which application of nanotechnology can make the current steel even better suited for the engineering applications. For instance, it can reduce the fatigue that is developed in the steel by cyclic loading. This can reduce the breakdown rick and maintenance cost. Employing vanadium and molybdenum nanoparticles can reduce the hydrogen embrittlement properties of the steel. Welds and joints are relatively weaker parts of any structure and are more vulnerable to breakdowns. Such areas are called as Heat Affected Zones or HAZs. Use of nanoparticles on magnesium and calcium make such areas stronger especially in plate steel. Nanotech can also cause a reduction in weight of steel used without compromising the strength. World’s largest steel producing firm ArcelorMittal (owned by Laxmi Mittal) has claims that it has a steel that can cut whooping 188 pounds from the body-in-white of a car. Body-in-white refers to the basic steel structure of any car.

Hydrated Cement
The main thing achieved by production of nanoparticles is that a tremendous increase in the surface area of particles. This property can be well used in strengthening the cement buildings. Alumina and silica nanoparticles can improve the hydration properties. Today’s sky creepers face a problem in cleaning the window panes from outside. Nanotech provides aid for this too. If the window pans are coated with titanium dioxide, the cleaning can be done by just a shower of rain. The hydrophilic properties of TiO2 do this for us. A fire resistant glass and a glass that prevent heat and sunlight can also be formed.
One more interesting application is production of wi-fi blocking paints. Such paints are already synthesized in Japan. These paints are blended with aluminum iron oxide which resonates at same frequencies that wi-fi network uses thus blocking them all. This can give you a 100% protection against hacking your wi-fi network. Even the aviation industry is not untouched. Weight of an aircraft is a major issue. Reduction in weight of steel used for manufacturing aircrafts will aid this industry like anything. A electrical application that is reduction in the weight of supercapacitors can help the hang gliders a lot. Supercapacitors are used in the assistant motors of a hang-glider.
Further inventions in the nanotech applications include things such as self-healing concrete, smog eating coatings and light emitting walls or ceilings. So this technology seems to be helping each and every field with promising solutions. A few more applications and the other side of the coin that is the ill effects of this technology will be discussed further.
