There is another, related, revolution going on at and below the molecular level, in information science and nanotechnology. This revolution capitalizes upon our growing understanding of the once forbidding world of quantum mechanics. This is enabling unexpected, rapid advances in quantum computing, which may endow laptops of year 2025 with more computing power than millions of today’s super computers. The age of computing has been with us for only a quarter century. A new age of quantum computing may have begun in 2007, with the announcement of the world’s first practical quantum computer ( Economist , Feb. 17, 2007).

The biomedical implications of the ongoing marriage of computational sciences and nanotechnology are especially auspicious. In 25 years, powerful, ubiquitous microscopic computers may be used as implants as sensors to monitor our bodily systems, to forecast weather, etc.

Nanotechnology- wet and dry

Nanotechnology has been heavily hyped, with some excessive claims. Still, it seems safe to say in 2014 that never before in history has one technology been so filled with promise, nor so potentially powerful, nor has any technological revolution happened as quickly. At the nanoscale, the boundaries separating traditional scientific and engineering disciplines become blurred to the point of non-existence. Therefore nanotechnology draws on many fields: physics, chemistry, mathematics, biology, computer science, engineering and clinical science. Much of nanoscale science and its growing applications are situated on the borderline or below the familiar world of classical physics and the spooky realm of quantum mechanics. To begin to understand the forbidding world of quantum mechanics, one must accept that a sub-atomic particle can be in two places at once: two electrons may establish a kind of telepathic link that transcends space and time. This is called quantum entanglement, long understood to apply in the inorganic world and now perhaps in biological systems.

Research focused on the nanoscale has uncovered new phenomenon that display properties of matter never observed before the turn of the century. Consider that the properties of matter change when taken down to nanosize. If the material in aluminum can is reduced to 25 nanometer size it would become pyrophoric, and explode spontaneously. Another manifestation: quantum dots two nanometers wide have different properties than those six nanometers wide: the former glows in blue light, the latter shines in red.

Nanoscientists and/or nanotechnologists work in either “wet” or “dry” nanofields. The dry, waterless side points toward valuable applications in energy efficiency and materials science, owing to the fact that some forms of carbon nanotubes are far stronger than steel, at one-sixth the weight as conductive as copper by volume and much better by weight. I note in passing that there are some quite unusual applications on the dry side, including Nano-ice, invented in Iceland, appropriately enough, in 2001. The process uses nanoparticles that eliminate the airpockets so detrimental to conventional freezing techniques. As a bonus, Nano-ice uses 90% less refrigerant and 70% less power than today’s ice-making machines. (Reference). The “wet side” (discussed in greater detail below), centers on study of biological systems that exist in a water environment such as human cells. And since everything that goes on in a human cell is nanotechnology, some go so far as to assert that most of 21st century biotechnology is a subset of wet nanotechnology.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
