A FUTURE PERFECT

Technology is beyond our explanations and expectations. We can not predict what will be its state tomorrow.

Electronic equipments are becoming smaller and faster. Computers from its first generations which used vacuum tubes .Now it’s on microprocessors. Very smaller and millions of times faster. According to Moore’s law the number of transistors is doubling in each 18 months .It was true in the past years and now. But our recent technology has a limit. The silicon made transistors in processors and other electronic equipments can not be even smaller.

So is it the end of our development, no it will not happen because a new technology has been raised, Nanotechnology. It is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. Nanotechnology is a sub classification of technology in colloidal science, biology, physics, chemistry and other scientific fields and involves the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale. What experts tend to agree on is that definition of nanotechnology involves control and characterization of properties at a molecular level, or perhaps an "nm length scale" level, rather than inferring (hence controlling) properties from macro-scale performance. Using nanotechnology we can make faster and very smaller machines.

Not only in the matter of computers it can influence, can every elements

Of life can be modified by that. Our houses will be smart homes, there will be wireless connectivity between every home appliance, and robots will do the works of homes.

And the houses will generate the electricity from sun.AC and TV will work as your

Wishes .Your clothes will be smart clothes which can clean themselves and adjust

the temperature, clothes will be computers with connectivity .in so many ways Nano technology will help mankind

More broadly, nanotechnology includes the many techniques used to create structures at a size scale below 100 nm, including those used for fabrication of nanowires, those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nanoimprint lithography, atomic layer deposition, and molecular vapor deposition, and further including molecular self-assembly techniques such as those employing di-block copolymers. However, all of these techniques preceded the nanotech era, and are extensions in the development of scientific advancements rather than techniques which were devised with the sole purpose of creating nanotechnology or which were results of nanotechnology research.

Technologies currently branded with the term 'nano' are little related to and fall far short of the most ambitious and transformative technological goals of the sort in molecular manufacturing proposals, but the term still connotes such ideas. Thus there may be a danger that a "nano bubble" will form from the use of the term by scientists and entrepreneurs to garner funding, regardless of (and perhaps despite a lack of) interest in the transformative possibilities of more ambitious and far-sighted work.

The National Science Foundation (a major source of funding for nanotechnology in the United States) funded researcher David Berube to study the field of nanotechnology. His findings are published in the monograph “Nano-Hype: The Truth behind the Nanotechnology Buzz.” This published study (with a foreword by Mihail Roco, head of the NNI) concludes that much of what is sold as “nanotechnology” is in fact a recasting of straightforward materials science, which is leading to a “nanotech industry built solely on selling nanotubes, nanowires, and the like” which will “end up with a few suppliers selling low margin products in huge volumes."

In the case of storage it is good to say about a recent development called ‘Blu-ray disc’ before saying about nano memories

Blu-ray is the recent technology in storage after VHS, CD and DVD. The blu-ray standard was jointly developed by Blu-ray Disc Association spearheaded by Sony. It is designed for high density storage and high definition video and audio. The wavelength of the laser used to read the data in blu-ray disc is 405nm other than 780 of the CD and 650 of the DVD. It is a blue-violet laser which has shorter wavelength than read laser in other optical media.

The thickness and diameter of the disc is same as a CD which is 1.2 mm and 12 cm respectively. But it can store the data of 70 CD’s in the dual layer version. Its smaller track pitch helps to increase the number of pits and lands in the disc; it also helps to increase the capacity.

OK, back to nano memory. Even the huge space of blu-ray cannot withstand higher storage needs of the next era. There also comes nanotechnology to help with excellent types of Nanomemories which capable of storing hundreds of movies into a place as same size as a sugar cube and all the books in the world on our palm.

It is special technology called nanorings which is atomic level rings of carbon and cobalt which can 0’s and 1’s in their different states. They are every small so they can exist in small spaces.

Holodeck will make the nanotechnology very useful .Holodeck is the very development in the communication facilities; it allows to broadcast an entire 3D image, sound and even smell to miles away. We can communicate to far away people as they are near us, more realistic than teleconference.

Nanotechnology will help to give fast connectivity to transfer this huge amount of data and the projection of 3D images.

Nanotechnology is very useful in fighting against diseases including cancer. The small nanorobots can get into our body and analyze the problems. Then they will fight against the viruses and bacteria, they will

Destroy the infected cell and repair the body parts.

A very interesting gift of nanotechnology is the utility fog. They are very small nanorobots which can change shape as the wireless controls. A single robot in the group is called a foglet.They are like fog when together. We can make them useful things by wireless commands. We can change its color too.

They had spherical body of 10 microns diameter. Each has 6 to 12 hands of 50 microns long.and3 fingers in each hand they can make many things joining its fingers and communicate each other. A microcontroller of 1000 MIPS capacity controls this system.

Make the things and make them invincible and visible at the required condition. It can cause teleportation in nonliving level .How about bringing your car in your garage to desired location invisible and like a fog floating in the air. That car is made of utility fog and you can make that house a washing machine or 2 motorbikes instantly.

They can even make a city in moon or mars .They will write a new chapter in space travel, surgery, healthcare etc.

A very important hope in the matter of nanotechnology is the research for defeating the death which is called cryonics .it freezes the dead without any harm to brain. Blood is removed and a nanochemical is filled in the veins.

It is secured -196 degree celcious cold metal cylinder awaiting a technology to bring them back to life .Nanotechnology may or may not raise them. Now abut 100 dead bodies are waiting to live again in the cryonics institute.

Then something about the risks of nanotechnology.

The mere presence of nanomaterials (materials that contain nanoparticles) is not in itself a threat. It is only certain aspects that can make them risky, in particular their mobility and their increased reactivity. Only if certain properties of certain nanoparticles were harmful to living beings or the environment would we are faced with a genuine hazard.

In addressing the health and environmental impact of nanomaterials we need to differentiate two types of nanostructures: (1) Nanocomposites, nanostructured surfaces and nanocomponents (electronic, optical, sensors etc.), where nanoscale particles are incorporated into a substance, material or device (“fixed” nano-particles); and (2) “free” nanoparticles, where at some stage in production or use individual nanoparticles of a substance are present. These free nanoparticles could be nanoscale species of elements, or simple compounds, but also complex compounds where for instance a nanoparticle of a particular element is coated with another substance (“coated” nanoparticle or “core-shell” nanoparticle).

Because nanoparticles are very different from their everyday counterparts, their adverse effects cannot be derived from the known toxicity of the macro-sized material. This poses significant issues for addressing the health and environmental impact of free nanoparticles.

To complicate things further, in talking about nanoparticles it is important that a powder or liquid containing nanoparticles is almost never monodisperse, but will contain a range of particle sizes. This complicates the experimental analysis as larger nanoparticles might have different properties than smaller ones. Also, nanoparticles show a tendency to aggregate and such aggregates often behave differently from individual nanoparticles.

But all the risks are survivable considering the limitless powers of nanotechnology and its gifts to mankind.

In the upcoming years we will see newer discoveries in nanotechnology. Man will not be satisfied even from that the world will develop more and more with man’s technology development till it ends by the same human hands.
