Thank You!
BISMILLAH-R-REHMAN-R-RAHEEM, as salam u alaikum, gud afternoon ladies and gentleman,*I shah hussain along wid nasir aziz am going to present my views on one of the most esteemed hot beaten topic in the field of science and technology, that is Nanotechnology, the next very small, though in absolute contrast in impact as compared to its physical show off.*In this presentation we are going to tell you, what actually nanotechnology is, how it is serving us in daily lives, what are its advantages and disadvantages and what the future of NT holds for us.*so what is NT?*by definiton as you can see its the art of manipulating matter at the nanoscale level
*Now Here a question arises how small the Nanoscale is?
*1. Its a bit difficult to realize how small the nano-scale is. To make things easier to get, we can say that one nanometre (nm) is one billionth of a metre.-2. Lets see some examples to make it clearIn the picture on the right, we can see a man staring at his picked hair trying to figuring out the diameter of it, he will essentially come to the conclusion that a human hair is 100,000nm thick, while a DNA molecule is only 2 nms wide.*Now this is a bit informative 3d chart, providing the size comparisons between different objects raised to the power of 10 meters. Here you can see, a 6 foot man is 1.62 meters or roughly around 2 billion nms tall. While on the other hand, a sample of a DNA molecule, as we have already seen in the previous slide, is approx. 2 nms long.*Who cares about nanotechnologyof course not only this guy.*We All Should care Because it can and most likely will bring revolution in the current industrialization and manufacturing processes.*The american govt is investing a wholesome of around 1 trillion USD/year.in different sectors, Some of which are mentioned in this chart.a big proportion of the r&d is being invested on materials and electronics field.*lets have a look how NT is leading us in different areas of expertise.. *e.g: in da field of electronics nanotransistors are becoming more nd more popular bcoz of its compactness..If u are thinking that this is a single transistor then you need to reshape your thinking, bcoz this is a transistor box containing thousonds of transistors in itSome other examples of nanoelectronics are Nanodiodes, OLEDs etc.
*The aapliances made with the help of nanoelectronics are getting its market share increasing and are becoming popular day by day due to the productivity and quality they have.Such as plasma Displays nd Quantum computing..*1-This is a nano-engineered battery, light in weight and flexible just like a paper. It can be rolled, twisted, folded or cut into a number of shapes with absolutely no loss of mechanical efficiency. Other energy suppliment examples with some change in their properties are fuel cells and solar cells*1-this rotating picture is actually a model of carbon nanotube, the strongest and stiffest materials discovered till to date. These tubes are the building block of almost all the NT objects.2- Aerogel. The worlds lightest crystalline solid3-and nano particles*Apart from the engineering and science discussed so far, NT also has its applications in medical sciences 1- this picture shows the process of Targeted drug delivery.. Which will enable mankind to diagnose nd treat all the major diseases such as cancer, HIV etc.2-. Artificial Retina and Tissue regeneration are the other examples of NT applications in life sciences..
*Although there are so many advantages to count about this incredible technology..We are going to Highlight some of them*With NT, we can create unique materials and products which are: Stronger, Lighter, Cheaper, Durable and even Precise all at the same time*1- computers can become a billion times faster and a million times smaller..2- Automatic cleanup of Pollution..3- Manufacturing at almost No cost..
*With the ongoing advancement of NT, diseases like cancer, aids, flu etc would become an illusion
And further more If any of you is interested to change the outlook of your body appearance
Here is a good news for you..
*Nothing is perfect in this World, so is NT..!Here are some of its disadvantages..*Loss of jobs (in manufacturing, farming, etc)
Carbon Nanotubes could cause infection of lungs
Oil & Diamonds could become worthlessAtomic weapons could be more accessible and destructive
*Now we are plugging into the future of Nanotechnology.
*In this slide, you can see how Nanotechnology could help redesigning the future of several technologies, products and markets. Scientists and engineers can now work with materials at the atomic level to create stain-proof fabrics, more efficient fuel cells and batteries
*1- In future, you might be reading news on foldable electronic paper..2- This is the proto type of Nokia Morph concept phone based purely on NT.. 3- Contact lens that will let you check your blood sugar level by looking into a mirror. (It is expected to be coming in 5 years or so.*This statement has obvious meaning that Nanotechnology is capable of changing the way almost everything is designed and made: from computers to clothing; from sports equipments to space ships and satellites; from cars to cancer therapies; from bridges to paint; and even objects and devices not yet imagined.
