Material Science research is now entering a new phase where
the structure and properties of materials can be investigated, characterized
and controlled at the nanoscale. New and sometimes unexpected material
properties appear at the nanoscale, thus bringing new excitement to this
research field. In this talk, special emphasis will be given to one-dimensional
nanotubes and nanowires because they exhibit unusual physical properties, due
to their reduced dimensionality and their enhanced surface/volume ratio. These
unusual properties have attracted interest in their potential for applications
in novel electronic, optical, magnetic and thermoelectric devices. Another feature of nanotechnology is that it is the one area
of research and development that is truly multidisciplinary. Research at the
nanoscale is unified by the need to share knowledge on tools and techniques, as
well as information on the physics affecting atomic and molecular interactions
in this new realm.
So now we are going to introduce the nano technology into
the field of robotics to achieve realistic movements which is a real dream of
the human for more than 5 years. By introducing this nervous system to the
robot we have exactly 2 advantages that is we can pass information same time
and we can also the movements at the same time the cars reached the actual part
where the movement as be caused. So we need have some knowledge about nano
technology and from these we are going to see what the nano cars means and then
how we are going to see the introduction of the nano cars into the neuron
system. From converting sunlight into power to clean oceans, to monitor thermal
environment, and to sensors in the form of biochips built into the human body
performing as lifesavers by self-monitoring and guarding, nanotechnology
assures us a lot more.
Stone Age,
Bronze Age, Iron Age, Silicon Age, and next what? Nevertheless to say, we are
well in to the Nanotech Age, where materials are just getting smarter day by
day. There would be sensors embedded in almost all walks of life. Each element
would be smart enough to repair itself as and when required. All this would be
possible by manipulating matter at the molecular scale.
Scientists will
now like to understand how simple atoms and molecules come together and arrange
themselves to form complex systems, such as living cells that make life
possible on earth. This approach deals with how complex systems are built from
simple atomic-level constituents which result in nanoscience and nanotechnology.
In simple, it is the study of properties of a few tens of atoms in a space of
less say 50nm. Manufactured products are made from atoms. The properties of
those products depend on how those atoms are arranged. If we rearrange the
atoms in coal we can make diamond. If we rearrange the atoms in sand we can
make computer chips. If we rearrange the atoms in dirt, water and air we can
make potatoes. Almost any manufactured product could be improved, often by
several orders of magnitude, if we could precisely control its structure at the
molecular level. We often want our products to be light and strong.
Nanoscience is emerging as the basic science providing a
field which is becoming the focus of attraction of all fundamentals sciences.
Physics provides possibility of maneuvering things atom by atom. Chemistry
provides way of synthesizing complicated molecules provided clues for building
materials on molecular level. Bioscience provides possibility of understanding
how nature builds the material as proteins are molecular machines, which
routinely manipulate individual atoms. To decipher it one needs mathematics and
computer science for modeling and computer simulations. The ultimate aim is to
achieve self assembly of devices for various applications. Of course,
nanotechnology is a wonderful tool, but what would happen if this technology
fell into the wrong hands? One might ask about the legal implications of
nanotechnology or even the harmful effects of bioterrorism. The truth is that
we simply don’t know where new technologies would lead, and we can never secure
against scientific terror. Today’s advances offer tremendous possibilities as
also tremendous risks-and we’re just going to learn to live with both.
