Electronic Equipment 's And Energy Storage

Nano-composite plastics and carbon nanotubes have been utilized for industrial and consumer packaging, the later offering an improved packaging solution for electronics components by making the materials used lighter and stronger. Nano-porous silica is a high porous, low-density solid material that supports various temperatures making it a great insulation product that can be applied in a wide range of fields from pipe insulation to refrigerators and even microelectronics. Nanoparticle based colloids are employed in the manufacturing of sunscreens, paints, and printer inks and nano-coatings can be applied in order to obtain scratch resistant surfaces. Composite nano-materials can be considered the basis for all the other current and future commercial applications of nanotechnology.

Nanotechnology is a novel technology what generally deals with structures and systems with a size less than 100nm. [1] Due to its unique tiny size, the properties are quite different from bulk properties include physical properties, chemistry properties, biological properties. For example, gold in bulk form is inert, but in nano scale, it tends to be very active. Moreover, different sizes, structures, and surface areas of gold nanoparticles make it exhibit different colors.

The idea of nanotechnology was first discovered by nobel prize winner physicist Richard Feynman in 1959. In the 1980 the first SPM was developed by IBM scientist in zurich. In 1991 a new form of carbon was discovered, the nanotube which was soon later on used for one of the building block for nanomaterial and nanomachines. In 1986 a book written by Eric Drexler spared the public interest in nanotechnology since the the NNI started by president Bill Clinton invested millions which in 2020 would turn into one trillion dollars. Nanotechnology is used in many things today like sunscreen, cars, in computers, medicine and in many other things to come in the future and in today's day and

Carbon nanotube have many structures, varing in length, thickness, and number of layers. Carbon nanotubes are graphene that has been rolled up into a tube-shape. Most significant use for carbon nanotubes is in structural reinforcement. Carbon nanofibres are extremely thin and light weighted, weighing about twentieth of a gram with one whole kilometer long. However, it was discovered that nanofibres are the ten times stronger than the strongest material, thus could strengthen almost any material. One of the significant uses of nanotube is acting as a carrier to transport drugs into the body. However, the use of nanotube in health care has become a debatable topic in today's society. Even though a nanotube is able to keep a particaular drug safe in its cage until it reaches a desired site where it can be released, scientists in Scotland have claimed that inhaling carbon nanotubes could be just as harmful as breathing in asbestos. They stated that "carbon nanotube can cause mesothelioma, a deadly cancer of the membrane lining in the body's internal

The discovery of graphene was given credit to the director of the center for Mesoscience and Nanotechnology at the University of Manchester, Andre Geim and his colleague Kostya Novoselev. The paper was published in October 2004 in Science Magazine. The title of the paper was "Electric field effect in atomically thin carbon films." The paper has become one of the most cited papers in material physics. Around the time of the discovery, carbon nanotubes was an interesting area of research. Geim was also interested in carbon nanotubes but had an idea about using them in an unfolded configuration. With the idea for the unfolded nanotubes he took a graphite block and polished it.

As the range of the implanted ions become comparable to the size of the small structures, important effects are taken in to account in experimental planning such as , structural changes induced by point defects, strongly enhanced dynamic annealing and sputtering. Even though a huge number of different nanomaterial systems can be realized with sophisticated synthesis methods, a lot of desired nanostructures will still remain inaccessible due to chemical and physical reasons. The main reason for that is, most of the synthesis method work close or even at thermodynamic equilibrium which is an ideal case. For example, superconductivity at higher temperatures is hard to achieve and yet under research. Issues like solubility limits or surface reconstructions are difficult or even impossible to overcome during synthesis. One alternative option is the subsequent modification of prepared nanomaterials such as Nano wires using energetic ion beam irradiation, which enables processes far from thermodynamic equilibrium. This can result into metastable phases of the nanomaterials/nanostructures with unusual or even exotic structural, electrical, optical or magnetic properties.

Carbon nanotubes get all of their impressive properties from their physical structure. They are hexagons of covalently bonded carbon atoms. A covalent bond is a bond between two non-metals atoms. Two of these atoms are bonded to four others and form another hexagon and these other hexagons exist on all the sides of the first and off of each other. This would look like a sheet of hexagons that could then be "wrapped" into tubes. These tubes can be single walled (SWCNTs), and multi-walled (MWCNTs) depending on the number of layers they have. The carbon atoms in these nanotubes have S2P2 chemical bonds (Zhang 7). This means that the atoms have one

The most clinically effective treatments for cancer were ironically incredibly detrimental to the human body 's health. These included, chemotherapy and radiation. These two methods did in fact destroy the malignant cells yet also caused apoptosis in healthy cells damaging them beyond repair and thus causing a great detriment to the patients health. However, recently, due to the endeavours of nanotechnology, it has been discovered that carbon nanotubes can effectively carry anti cancer drugs destroying the malignant cancer cells without damaging the healthy cells, in other words, the

Reducing toxicity of therapeutic materials is the main aim of developing drug-delivery systems that is achieved using CNTs.1, 2 The intense interest in CNTs is due to the capability of adsorbing or conjugating with a wide variety of medicinal molecules and their unique chemical and physical properties and potential applications from high strength and low weight nanocomposite materials to electronic devices. Drug molecule penetrate through the cancer cell by CNT to treat diseases and thereby potentially reducing the drug side effects by preserving the non-targeted tissues of the patients.3-5 The

Molecular technology has become the talk of mainstream science and technology today. As the aviation industry searches for new forms of efficient aviation, molecular technology would be the only logical place to start. For this report the various beneficial uses of carbon nanotubes, in form of buckminsterfullerene, will be both discussed and theorized.

Various types of nanowires have been fabricated using different methods, including evaporation [16], laser ablation [17], chemical vapor deposition (CVD),

The paper reports that a double walled carbon nanotube (DWNT) was fabricated for the purposes of conducting transport experiments. These DWNTs were fabricated by a microelectromechanical systems (MEMS)-compatible process. First a vertical array of DWNTs were grown on a silicon chip used as a substrate by a catalytic chemical vapour deposition
