Question

Nature always gives the valuable inspiration to improve engineering and science.
List at least 3 examples where we can learn nanoscience and technology.

Answer 1

3 example where we can learn nanoscience and technology

1. The detergent that we use in our daily lives uses nanoscience in order to clean products better. this can be done in three ways

a. With the help of nanotechnology, it can Produce films that can be applied to surfaces and these films keep help in keeping surfaces clean. This technology can keep your car's windshield clean and also improve the visibility when you're driving in the rain.

b. Using nanoparticles in detergents make it work better while producing less environmentally harmful byproducts.

c. Nanotechnology uses materials in the cleaning process that are antibacterial such as silver nanoparticles (nanosilver) and Titanium oxide (TiO2) nanoparticles. here we should note that there should be regulation in use of silver nanoparticles because they may harm useful bacteria in groundwater (lakes etc). Titanium oxide (TiO2) nanoparticles use the energy in light to kill bacteria on the surface.

2. In our daily lives, we use smart-phone, laptop and tablets and all these pieces of equipment have billions of transistors. These transistors are in the range of each of them less than a 100 nanometer in width. Semiconductor industry manufactures kinds of stuff at the nanometer scale.

3. Conventional techniques are not adequate to solve the problem of massive oil spills. In recent years, nanotechnology has emerged as a potential source of novel solutions to many of the world's outstanding problems. Although the application of nanotechnology for oil spill cleanup is still in its nascent stage, it offers great promise for the future. In the last couple of years, there has been particularly growing interest worldwide in exploring ways of finding suitable solutions to clean up oil spills through use of nanomaterials. Graphene-coated Carbon-based aerogels have attracted interest in various fields due to their unique physical properties, such as low apparent density, porosity, and specific surface area. As sorbent materials, graphene/CNT hybrid foam, and exhibit very high sorption capacities, good recyclability and environmental friendliness.
