Simulation Methods in Nanotechnology

Scalable space–time multiresolution algorithms implemented on massively parallel computers enable large-scale molecular dynamics (MD) simulations involving up to a billion atoms. Multimillion atom MD simulations are performed to study critical issues in the area of structural and dynamical correlations in nanostructures. Simulation research is focused on a few semiconductor, ceramic, and metallic nanostructures. These nanostructures systems include: nanometer-scale stress patterns in silicon/silicon nitride nanopixels; self-limiting growth and critical lateral sizes in gallium arsenide/indium arsenide nanomesas; structural transformation in colloidal semiconductor nanocrystals; nanoindentation of crystalline and amorphous silicon nitride films; and dynamics of oxidation of metallic aluminum nanoparticles.

NANO-RADIO


The carbon nanotube radio consists of an individual carbon nanotube mounted to an electrode in close proximity to a counter-electrode, with a DC voltage source, such as from a battery or a solar cell array, connected to the electrodes for power. The applied DC bias creates a negative electrical charge on the tip of the nanotube, sensitizing it to oscillating electric fields. Both the electrodes and nanotube are contained in vacuum, in a geometrical configuration similar to that of a conventional vacuum tube.
Incoming radio waves cause the tube to vibrate. The tube itself can be "tuned" to respond to vibrations that match certain frequencies, or "channels" on the radio dial.

Scanning Electron Microscope




SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes have developed new areas of study in the medical and physical science communities. The SEM has allowed researchers to examine a much bigger variety of specimens.
The scanning electron microscope has many advantages over traditional microscopes. The SEM has a large depth of field, which allows more of a specimen to be in focus at one time. The SEM also has much higher resolution, so closely spaced specimens can be magnified at much higher levels. Because the SEM uses electromagnets rather than lenses, the researcher has much more control in the degree of magnification. All of these advantages, as well as the actual strikingly clear images, make the scanning electron microscope one of the most useful instruments in research today.

Transmission Electron microscope


























This instrument employs a beam of electrons to image the specimen and no light is involved. An image of the specimen is viewed on a phosphor coated screen and the final pictures, called electron micrographs, are made on photographic plates or film. The source of the electrons is a heated tungsten filament, a single Lanthanum Hexaboride crystal, or a very sharp metal tip. The electron beam is accelerated down a vertical column (under vacuum) by high voltage and focused by electro-magnetic lenses. Electrons cannot be focused by glass lenses. In fact, even very thin glass will stop an electron beam. The voltages used to accelerate the beam can be from a few thousand up to a million volts in some research instruments. The usual potential is somewhere between 10 000V and 150 000V in routine instruments. Specimens for examination by TEM need to be very thin, of the order of 50 nanometers or less.

A common method for the preparation of biological specimens is sectioning. Fixed biological material is infiltrated with a plastic, often Methacrylate or an epoxide such as Araldite, which hardens to a solid block. Very thin slices, or sections, are cut from this block with an Ultra-Microtome using a glass or diamond knife. The sections are mounted on copper grids for examination in the TEM. Metals and other conducting material can be thinned by chemical means, mechanical polishing, or by electrolysis.

Specimens such as virus particles, proteins or DNA molecules are placed on very thin carbon films on a copper grid made by the evaporation of carbon in high vacuum. Specimens are usually stained or shadowed with heavy metal to increase the contrast. It has taken decades to develop suitable methods for EM preparation and it is still the most difficult part of the process.

Nanotubes and Fuel Cells

Researchers report hydrogen storage by silicon nanotubes exceeds that of their carbon couterparts. Silicon could play a large role in the emergence of "clean" hydrogen fuel cell vehicles.


After powering the micro-electronics revolution, silicon could carve out an important new role in speeding the debut of ultra-clean fuel cell vehicles powered by hydrogen.


Researchers have focused on the potential use of carbon nanotubes for storing hydrogen in fuel cell vehicles for years. Despite nanotubes’ great promise, they have been unable to meet the hydrogen storage goals for hydrogen fuel cell vehicles. A more efficient material for hydrogen storage is needed. Using powerful molecular modeling tools to compare the hydrogen storage capacities of newly developed silicon nanotubes to carbon nanotubes. In theory, silicon nanotubes can absorb hydrogen molecules more efficiently than carbon nanotubes under normal fuel cell operating conditions.


The calculations pave the way for tests to determine whether silicon nanotubes can meet standards for hydrogen storage.

Field Emission Display Through CNTs


















◆What is Field Emission Display?

Field Emission Theory: By applied a high electric field to a conductor, the effective energy barrier of the conductor surface will reduce and the barrier wall will become low. So the electrons will easily tunnel through the energy barrier and emit from the surface of conductor. Field Emission Display is a kind of display technologies, which works base on the field emission theory. See figure 1,2 and 3 for comparison it with CRT .

NanoBiotechnology In Jamia Hamdard

Jamia Hamdard plans to set up a nanobiotechnology centre to facilitate research in the field. A faculty has been selected to carry out research and training as well as to chalk out a Masters course in nanobiotechnology soon. The course will be a five-year doctoral programme.
Fascinated by the principle behind nanotechnology, which is reducing the size of a product and increasing its efficiency manifold, S Ahmad, vice chancellor of the university decided to start the first of its kind research centre at Jamia Hamdard.
Elaborating on the areas which will be at the core of the research projects, Ahmad said, As the name suggests nanobiotechnology means using tiny tools to learn about living things. By using nanotechnology, we can change the genetic code of the human body. The deficiencies in the body can be cured by using tiny and efficient tools once the problem is identified, added Ahmad.
In drug delivery even minuscule alterations to the surface of the nanobased structures can affect the toxicity of the individual cells. Toxicity is desirable for particles that kill cancer cells or harmful bacteria. So, biotechnology associated with nanotechnology can revolutionise human life, he said.
The faculty will be interdisciplinary in nature. We have invited faculty members of other science subjects to conduct experiments to improve their scientific and technical expertise. We will also register students to this department who are interested in innovations and honing their technical skills, he added.
The budget required is Rs 1,500 crore. Since it is a deemed university, Jamia Hamdard does not get grants from University Grants Commission (UGC). We have sent requests to various ministries for financial aid. As of now, we are funding the programme from our own resources, said Ahmad.
The vice chancellor has also sent a proposal to the Department of Science and Technology (DST) to introduce nanotechnology from kindergarten to nurture young scientists. According to him, the proposal is under consideration. We need 15-20 years to shape a scientist in this field. By the time students complete their graduation and think of selecting nanotechnology as their area of expertise, other subjects have already consumed much of their time and attention.

NANOCRYSTALS

A nanocrystal is a crystalline particle with at least one dimension measuring less than 1000 nanometers (nm), where 1 nm is defined as 1 thousand-millionth of a meter (10-9 m).
Nanocrystals have a wide variety of proven and potential applications. They have been used in the manufacture of filters that refine crude oil into diesel fuel. Nanocrystals can also be layered and applied to flexible substrates to produce solar panels. Titania nanocrystals can be suspended in liquid form and applied to surfaces, making it possible to literally paint a solar panel onto an exterior wall or roof.


Possible future uses of nanocrystals include:
Production of hydrogen
Removal of pollutants and toxins
Medical imaging
Bio-tags for gene identification
Drug manufacture
Protein analysis
Flat-panel displays
Illumination
Optical and infrared
lasers
