Introduction to Nanotechnology:
About Nanotechnology, Nano-medicine, Nano-tubes and everything else Nano:
Imagine a world where we have ability to understand and control matter at nano-scale, where unique phenomena enable novel applications. A planet where novel materials facilitate entirely new approaches to design and production that is faster and better than ever before.
"Imagination will often carry us to worlds that never were."
Nanotechnology exhibits at upcoming USA Science & Engineering Festival will provide a compelling peek into this world of small-scale engineering for oversized opportunities. Reveal how advanced manufacturing capabilities are linked hand-in-hand alongwith advanced materials and are completely changing how we make everything. You will get a glimpse into materials-based revolution that is opening door to vast opportunities we have only begun to imagine.
Far more than mere engineering at ever smaller dimensions, our expanding abilities to observe and manipulate matter at Nano-scale enable us to leverage unique physical, chemical, mechanical and optical properties of materials which take place at that scale to produce superior, multifunctional applications that are key discriminators for our technology platforms -in air, on land, at sea and in space.
These advanced materials initiatives, combined with our advanced manufacturing initiatives, form foundations for affordable solutions, systems, innovative also products that we are already realizing not only in aerospace and defence but in security, renewable energy, sustainable manufacturing, healthcare, robotics and computing.
Advantages and Disadvantages of Nanotechnology
While nanotechnology is seen as way of future and is a technology that a lot of people think will bring a lot of benefit for all which will be using it, nothing is ever perfect and there will always be pros and cons to everything. Advantages and disadvantages of nanotechnology can be easily enumerated and here are some of them:
Advantages of Nanotechnology:
To enumerate advantages and disadvantages of nanotechnology, let us first run through good things this technology brings:
1. Nanotechnology can in fact revolutionize a lot of electronic procedures, products and applications. Areas that benefit from continued development of nanotechnology when it comes to electronic products include Nano transistors, Nano diodes, OLED, plasma displays, quantum computers and many more.
2. Nanotechnology can also benefit energy sector. Advancement of more effective energy-absorbing, energy-producing and energy storage products in smaller and more efficient devices is possible with this technology. Items such as fuel cells, batteries and solar cells can be built smaller but can be made to be more effective with this technology.
3. Another industry that can benefit from nanotechnology is manufacturing sector that will need materials like Nanotubes, Aero-gels, Nano particles and other similar items to produce their products with. These resources are more durable, often stronger and lighter than those that are not produced with help of nanotechnology.
4. In medical world, nanotechnology is also seen as a boon since these can help with creating what is called smart drugs. These help cure people faster and without side effects that other traditional drugs have. You will also find that research of nanotechnology in medicine is now focusing on areas such as bone repair, tissue regeneration, immunity also even cures for such ailments like cancer, diabetes and other life threatening diseases.
Disadvantages of Nanotechnology:
When tackling advantages and disadvantages of nanotechnology, you will also need to point out what can be seen as negative side of this technology:
1. Included in list of disadvantages of this science and its development is possible loss of jobs in traditional farming and manufacturing industry.
2. You will also find that development of nanotechnology can also bring about crash of certain markets due to lowering of value of oil and diamonds due to possibility of developing alternative sources of energy that are more efficient and won't require use of fossil fuels. This can also mean that since people can now develop products at molecular level, diamonds will also lose its value since it can now be mass produced.
3. Atomic weapons at present are more accessible and made to be more powerful and more destructive. These can also turn into more accessible with nanotechnology.
4. Since these particles are very small, problems can actually arise from inhalation of these minute particles, much like problems a person gets from inhaling minute asbestos particles.
5. Currently, nanotechnology is very expensive as well as developing it can cost you a lot of money. It is also pretty difficult to manufacture that is probably why products made with nanotechnology are more expensive.
