What are the latest developments about nanotechnology and climate change?
It is believed that nanotechnology will likely decrease the need for fossil fuels, thus having a positive impact on global warming . Nanotechnology and its products (or nanomaterials) mainly involve in the applications of renewable energies (e.g., solar and hydrogen fuel cells), which result in nearly zero emissions.
Will nanotechnology improve our way of life in the next 20 years?
In the next 20 years , nano-technology will touch the life of nearly every person on the planet. The potential benefits are mind boggling and brain enhancing. But like many of the great advancements in earth’s history, it is not without risk.
Who is developing nanotechnology?
The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used.
Do nanotechnology improve our society?
Nanotechnology is helping to considerably improve , even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.
Can nanotechnology be harmful?
Out of three human studies, only one showed a passage of inhaled nanoparticles into the bloodstream. Materials which by themselves are not very harmful could be toxic if they are inhaled in the form of nanoparticles. The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems.
How does nanotechnology help the environment?
Therefore, by detecting pollutants by specific sensors, we can help protect the sustainability of human health and the environment . Thus, nanotechnology provides us with a new approach to cut down the waste production, reduce the emission of greenhouse gases and discharge of hazardous chemicals in water bodies.
Does nanotechnology have a future?
