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

What will be after Nanotechnology ?












ANGOTECHNOLOGY
Now the challenge is to push nanofabrication to the scale of single nanometers and even Angstroms.
Historically, the Ångström is named after the Swedish physicist Anders Jonas Ångström (1814–1874), who was one of the founders of spectroscopy. In 1868, Ångström introduced a spectrum chart to systematize solar radiation. The chart expressed the wavelength of electromagnetic radiation of the Sun in multiples of one ten-millionth of a millimeter, now called Angstrom. To give an example, the width of a human hair is typically about one million Angstroms.To make electronic devices with dimensions of a few Angstroms a new technology needs to be developed. Such Angstrom-resolution technology, or angotechnology, to be efficient, needs to provide tools to manipulate single atoms. Recently a possible approach to angotechnology was suggested in a paper by Aref, Remeika, and Bezryadin. Their idea is based on two facts: (1) Single atomic layers of graphite, known as graphene, are now available to scientists through the developments of Novoselov and collaborators. (2) The electron beam in a modern high-resolution Transmission Electron Microscope can be focused into a spot of only half an Angstrom. Remarkably, the electron focus spot diameter is smaller than the distance between neighboring atoms in graphene, which is 1.4 Angstroms. It is suggested by some researchers that if a highly focused e-beam of a TEM should be able to push single atoms from a suspended graphene layer. In order to illustrate the idea, Aref and collaborators focused an electron beam on a carbon nanotube, which is composed of a few rolled layers of graphene. It was indeed possible to remove atoms from the nanotube. The size of the resulting holes was about 20 or 30 Angstroms, which corresponds to hundreds of atoms removed. Although the power of the 2 00 keV e-beam to expel atoms from graphene is evident, the possibility to remove single atoms at will remains to be demonstrated in the experiment. The authors of the paper argue that further optimization of the method should allow the electron-beam expulsion of single atoms (EBESA) from the graphene. The EBESA, when achieved, will be the key to angofabrication and angotechnolgy. Many group compete to achieve the goal of a controlled expulsion of single atoms. This will allow one to fabricate devices with a truly atomic precision, simply by removing unwanted atoms from a monoatomic film, such as graphene.
The image given above illustrates the principle of EBESA, suggested as an approach to the development of angotechnology. There, a ficused beam of electrons (red) targets single atoms of graphene and expels them, on a one-by-one basis. Thus graphene-based electronic devices of any shape can be produced, with atomic precision. The figure above shows a prototype tripod device (green).

Clean Water from Nanotechnology


New technology that can absorb toxic chemicals from ground water — a technology that could soon find its way into water purification systems. To refine the method using Dendritic Nanotechnologies' Priostar dendrimer-based nanotechnology. Dendrimers are spheroid or globular structures engineered to carry specific molecules in their interior empty spaces or on their surface.
The primary target for the purification system will be perchlorate — a groundwater contaminant found in several regions — which has been found to adversely affect the health of women by interfering with iodide absorption in the thyroid gland. Researchers believe it will also prove effective at removing and recovering metals such as chromium and lead and contaminants such as arsenic from groundwater.

"Not only this technology serve the legislative and environmental requirements in a cost effective manner.The economic need for a water remediation and recovery system that is cost effective, recovers precious metals for recycling, and releases water that exceeds the Clean Water Act standards back into the environment will be highly desired worldwide.

HOW CNT CAN GROW ON SUBSTARTE







Process for Thin Film Coating

Before go to the process for the CNT growth on to the substrate,it is essential first to formed the thin film on to the substrate.We used quartz substrate in this process (glass,silicon wafer etc can also be used) and develop thin film on it by using RF Plasma Sputtering (others process can also be used).Its a very simple process for thin film coating on to the substrate.First placed the substrate at the desired location in the chamber,creating the vaccum and starting firing of plasma in it for certain time.Due to the ionic bombardment onto the target,material have been deposited onto the substrate.Now the sample is ready to grow the CNT/any other material on it.

CNT can be grown by using many methods:
a) Ion discharge
b) CVD
c) Laser Ablation etc

But we used CVD process at atmospheric pressure to grow CNT onto the quartz substrate:-
STEPS:---

1):- First put the sample in the boat after cleaning the boat from acetone and insert it in the
CVD chamber

2):- Plug on the supply,Set Temp: 800 degree celcius approx and set voltage level upto 200
volts (Note: These parameters depend on the type of substrate used)

3):- Now wait till the temperature reach upto 8oo degree celcius.(Note: In our case it consume
approx 20-30 mins to reach the set temperature value.

4):- When achieve the desired temperature,get ready to pass the gases from the chamber

5):- Pass the Argon gas from the chamber which act as a inert gas for five minutes using Mass
flow controller.(Set 50 but it can be changed like can set 100 too)

6):- Now Pass the Acetylene (IUPAC name: ethyne), C2H2 from the chamber
for ten minutes using Mass flow controller..(Set 20 but this parameter can be changed too.
Note:Some other Catalyst can also be used to grow CNT like some researchers used Resin and become succeed to grow CNT on it .

7):- Now turn off the supply and the developed sample is ready to characterized it from a
Microscopy Techniques eg SEM,TEM etc (We used SEM for it and see the fine CNT structures have been developed onto the substrate.

Points to Remember:-

MWCNTs synthesized with low acetylene concentration are more regular and with a lower amount of amorphous carbon than those synthesized with a high concentration. During the synthesis of CNTs, amorphous carbon nanoparticles nucleate on the external wall of the nanotubes. At high acetylene concentration carbon nanoparticles grow, covering all CNTs’ surface, forming a compact coating. The combination of CNTs with this coating of amorphous carbon nanoparticles lead to a material with high decomposition temperature.

3T MRI

All MRI machines are calibrated in "Tesla Units". The strength of a magnetic field is measured in Tesla or Gauss Units. The stronger the magnetic field, the stronger the amount of radio signals which can be elicited from the body's atoms and therefore the higher the quality of MRI images.

1 Tesla = 10,000 Gauss
Low-Field MRI= Under .2 Tesla (2,000 Gauss)
Mid-Field MRI= .2 to 0.6 Tesla (2,000 Gauss to 6,000 Gauss)
High-Field MRI= 1.0 to 1.5 Tesla (10,000 Gauss to 15,000 Gauss)


Advantages of 3 Tesla MRI

The 3T MRI has twice the field strength of most conventional MRI scanners, which typically operate at 1.5 Tesla. The 3T strength can increase the imaging resolution by 16 times. Tesla is a unit of measure for magnetic field strength. Three tesla is equivalent to 30,000 times the earth’s magnetic field. The 3T MRI captures images with a level of detail, clarity and speed never before possible.

Some of the procedures that the 3T MRI system will particularly benefit include:
MR angiography
• Neurological/brain imaging
• Spine studies • Orthopedic – including elbow, wrist, hip, knee, foot and ankle
• Prostate
• Pelvis – Male and Female
• Abdominal
• Functional imaging, spectroscopy, and brain fiber tracking

CNT CAN CAUSE LUNG CANCER


While carbon nanotubes are being used more and more in the chemistry and electronics industries, a study published by the Nature Nanotechnology Journal has found that these nanotubes may cause the human body the same harm as asbestos.
These artificially created molecules are currently in use in many products, including tennis rackets, baseball bats, and bicycle handlebars. Because companies are not required to disclose the information, consumers are unable to know the exact use and amounts of the nanotubes.
Researchers noted that nanotube fibers are very similar to asbestos fibers, and studied their effects on bodies of mice. Asbestos, varying lengths of carbon nanotubes, and normal flat carbon sheets were injected into the abdomens of mice. These researchers found that long carbon nanotubes cause inflammation and scarring in the lining of the lungs and stomach—an effect of exposure to asbestos.
Asbestos lawyers, health advocates and researchers have come to support a more cautious approach when dealing with nanotechnologies.
Those in manufacturing plants may not be the only ones at risk; people who demolish the products, throw the products into landfill sites, or incinerate the products may be subject to carbon nanotube exposure.

NANO SIZE OBAMA




At the University of Michigan, Researchers has used nanotechnology to create images of Barack Obama, the next president of the United States. Each Obama face is made up of 150 million vertically-aligned carbon nanotubes grown at really high temperatures and imaged with a scanning electron microscope.Carbon nanotubes are tiny hollow cylinders of carbon that are tens of thousands of times smaller than a human hair, but several times stronger and stiffer than steel.


HOW THEY ARE MADE:-
The nanobama structures are made of carbon nanotubes, and the pictures were taken using optical and electron microscopes. Carbon nanotubes (CNTs) are tiny hollow cylinders of carbon; the diameter of a CNT is tens of thousands of times smaller than a human hair, and CNTs are several times stronger and stiffer than steel. CNTs are grown by a high-temperature chemical reaction, using patterns of nanoscale metal catalyst particles arranged in the shapes of the faces, text, and flags that you see in the images. Each face contains millions of parallel nanotubes, standing vertically on the substrate like a forest of trees. If you were standing next to the nanotubes as they grow, and each nanotube was a 1 foot (0.3 meter) diameter tree, the trees would be growing at over 500 miles per hour! The nanobama faces are approximately 0.5 millimeter wide, or about ten times the width of a human hair.

The nanobamas are made as follows, and as shown in the diagram above:-
(1) convert an image of Barack Obama to a line drawing
(2) shrink the drawing and print it onto a glass plate (mask), using a laser system
(3) shine ultraviolet light through the mask, and onto a thin layer of polymer on a silicon wafer, thereby patterning the polymer by photolithography
(4) coat the wafer with a thin layer of catalyst nanoparticle "seeds" for nanotube growth
(5) remove the remaining polymer, leaving the catalyst seeds in the shapes of the nanobamas
(6) grow the CNTs from the catalyst patterns, by placing the wafer in a high-temperature furnace and filling the furnace with a carbon-containing gas
(7) take pictures of the structures, which are barely visible to the naked eye, using electron and optical microscopes

Beyond the nanobama fun, carbon nanotubes and other nanostructures are building blocks for many important technological advances. These include high-performance solar cells and batteries, new methods of diagnosing and treating disease, next-generation computer processors and memory, and lightweight composite materials. Broad awareness and understanding of the widespread benefits, implications, and potential risks of nanotechnology will be essential for its commercial success. Likewise, public and private support for research and education programs catalyzes economic growth and enables continued breakthroughs in energy, medicine, communications, and other vital areas.

MAGNETIC NANOPARTICLES IN DIAGANOSIS

Magnetic Nanoparticles helps in detecting cancer
MRI is one of the tools for doctors that can help in diagnosis of cancer cells. In this technique magnetic waves are used for detecting different types of tissues. Researchers have found that magnetic nanoparticles can help in identifying cancer cells especially during MRI scan.
A team of researchers found that these magnetic nanoparticles binds themselves to the cancer cells and act as radio transmitters and therefore enhance the capabilities of MRI detection.
The finding of the research have been published recently in an online journal of American Chemical Society where the researchers claim that they have fabricated smallest magnetic nanoparticle and after coating it, the nanoparticle enhances the MRI signal.
The researchers fabricated peptide-coated iron oxide nanoparticle and it was injected to the mice for locating a tumor cell known as U87MG. A perfect size of the nanoparticle and a particular peptide coating thickness was achieved and this magnetic nanoparticle was found to give best results
