TEXT 1 CARBON NANOTUBES

In the last years there has been an increasing interest in nanoscience, basically to understand the behavior of structures with sizes close to atomic dimensions. Even when many nanostructures are currently under investigation, the area of nanotubes is one of the most active. Carbon nanotubes (CNTs) present one of the simplest chemical composition and atomic bonding configuration. Since their discovery in 1991 by Jijima, carbon nanotubes have been the target of numerous investigations due to their unique structural, electronic and mechanical properties.

There are two groups of nanotubes, multi-wall (MWCNTs) and single-wall (SWCNTs) carbon nanotubes. MWCNTs can be visualized as closed graphite tubules with multiple layers of graphite sheet defining a hole typically from 2 to 25 nm separated by a distance of approximately 0.34 nm. SWCNTs are real single large molecules.

It is important to define the chiral vector of nanotubes C_h,which is given by C_h=na₁=5 a_2,where a₁and a₂are unit vectors in the two-dimensional hexagonal lattice, and n and m are integers. The ends of the chiral vector meet each other when the graphene sheet is rolled up to form the cylinder. According to this, tubes of different diameters and helical arrangements of hexagons can arise by changing the values of n and m. In other words, depending on the values of n and m it is possible to have different nanotube structures. In fact, depending on how the two-dimensional grapheme sheet is rolled up, there are three types of carbon nanotubes, armchair, zigzag and chiral. Armchair nanotubes are formed when n=m, and the chiral angle is 30^0.Zigzag nanotubes are formed when eithern or m is zero and the chiral angle is 0^0.The combination of size, structure and topology give CNTs important mechanical properties such as high stability, strength and stiffness, low density and elastic deformability with interesting surface properties. These electronic properties open the doors to a wide range of fascinating electronic applications.

dimension – размер

carbon nanotubes (CNT) – углеродные нанотрубки

atomic bonding – атомные связи

multi-wall (MWCNTs) carbon nanotubes – многостенные углеродные нанотрубки

single-wall (SWCNTs) carbon nanotubes – одностенные углеродные нанотрубки

approximately – приблизительно

two-dimensional hexagonal lattice – двумерная гексагональная (шестиугольная) кристаллическая решетка

helical – спиралевидный, винтовой

PROPERTIES OF MATERIALS

Densityis the amount of mass per unit volume. It is measured in kilograms per cubic meter. The density of water is 1000 kg/m³, but most material have higher density and sink in water. Aluminium alloys, with typical densities around 2800 kg/m³,are considerably less dense than steel, which has typical density around 7800 kg/m³. Density is important in any application where the material must not be heavy.

Stiffness(rigidity) is a measure of resistance to deformation such as stretching or bending. The Young modulus is a measure of resistance to simple stretching or compression. It is the ratio of the applied force per unit area (stress) to the fractional elastic deformation (strain). Stiffness is important when a rigid structure is to be made.

Strengthis the force per unit area (stress) that a material can support without failing. The units are the same as those of stiffness, MN/m^{2, but}in this case deformation is irreversible. The yield strength is the stress at which a material deforms plastically. For a metal the yield strength may be less than the fracture strength, which is the stress at which it breaks. Many materials have a higher strength in compression than tension.

Ductilityis the ability of the material to deform without breaking. One of the great advantages of metals is their property to be formed into the shape that is needed, such as car body parts. Materials that are not ductile are brittle.

Toughnessis the resistance of the material to breaking when there is a crack in it. For a material of given toughness, the stress at which it will fail is inversely proportional to the square root of the size of the largest defect. Brittle materials have low toughness: glass can be broken along a chosen line by first scratching it with diamond. Composites have considerably greater toughness than their constituent materials. The example of a very tough composite is a fiberglass that is very flexible and strong.

What is Nanotechnology?

Over the past few decades, the development of new and more advanced energy technologies with the capability of improving life all over the world have been sought in the field of science and engineering. In order to make the next leap forward from the current generation of technology, scientists and engineers have been developing the new field of science called Nanotechnology.

Nanotechnology is defined as the science and technology of building electronic circuits and devices from single atoms and molecules, or the branch of engineering that deals with things smaller than 100 nanometers. A nanometer (nm) is one billionth of a meter, roughly the width of three or four atoms. For scale comparison, the average human hair is about 80,000 nanometers wide, and a single virus particle is about 100 nanometers in width. The prefix nano- comes from the Greek words nanos, meaning “dwarf.” The term Nanotechnology is also often used to describe the interdisciplinary fields of science devoted to study and use of nanoscale phenomena.

The story of nanotechnology began in the 1950s and 1960s, when the most engineers were thinking big not small. This was era of big cars, big jets, the world’s largest oil tankers, huge skyscrapers and big plans for sending people into outer space. Other researchers, however, focused on making things small. The invention of the transistor in 1947 and the first integrated circuit(IC) in 1959 launched an era of electronics miniaturization. It was these small devices that made large devices, such as spaceships, possible. After successfully splitting the atom in the years before World War II, physicist tried to understand about the particles from which atoms are made, and the forces that bind them together. At the same time, chemists worked to combine atoms into new kinds of molecules, and had great success in converting the complex molecules of petroleum into all sorts of useful plastic.

Nanomedicine

Nanomedicine is an area of biomedical research that seeks to use tools from the field of nanotechnology to improve health. Scientists say that physical, chemical, and biological properties of materials at the nanoscale differ in fundamental way from the properties of large –sized matter. For example, nanotechnology could provide new formulations and new routes to deliver drugs to previously inaccessible sites in the body, thereby broadening a drug’s potential. Tiny sensors, that detect diseases in the body far earlier than existing diagnostic tools, are among the promising areas of research. In today’s world of biomedical tools and therapies, pocket –sized electrocardiographs for monitoring the heart have appeared, and diagnostic cameras the size of a vitamin can travel the length of a digestive tract. The extremely small size of nanomaterials also means that they are much more readily absorbed by a human body than large-sized particles.

SOLAR ENERGY

Solar power, also known as solar energy, is the technology of obtaining usable energy from the light of the sun. Solar energy has been used in many traditional ways for centuries, and has come into widespread use where other power supplies are absent, such as in remote locations and space. Solar energy has a number of applications including

· Heat (hot water, heating building, cooking)

· Electricity generation (photovoltaic, heat engines)

· Desalination of sea water

Solar power is an extremely clean way to generate electricity. There are no air emissions associated with operation of solar modules. Photovoltaic, solar water heating systems reduce power generation from traditional sources and associated environmental impacts. Solar thermal energy is one of the best ways to lower carbon dioxide content and to protect the environment. Typically, greenhouse gas emissions from heating water account for over 70%. A solar water heater is one of the most influential and economical ways to reduce greenhouse gas emissions. There are a few of the environmental reasons to install a solar thermal system:

· To reduce greenhouse gas emission.

· Two-collector domestic hot water systems can offset over 2 tons of CO₂ per year or 50 tons over life of the system.

· On-site generation, that is to reduce the need to mine and transport fossil fuel energy.

· Increased water heater life expectancy.

When comparing the merits of water heating systems, it is important to differentiate between capital and running costs. Conventional water heating systems tend to be cheap to install, but require the purchase of fuel. Fuel prices are currently low, but will rise in future. Solar thermal heating systems seem to be more expensive to install, but don’t need any fuel. A solar thermal system will incur very low running costs, and the payback on the capital costs will be better, because fuel costs of oil or gas systems go up over the time.

SOLLAR COLLECTORS

A solar collector is a device which collects sunlight and converts it into a heat. It consists of the following parts: 1. A glass cover made of either a single a double sheet of glass. 2. Water tubes. These are usually made of aluminium or steel. 3. A flat metal plate. This is painted black and usually made of aluminium, steel or copper. 4. Insulation. This can be any insulating material which can withstand temperatures up to 200^oC. In India, for example, dried palm leaves have been used. 5. A casing that can be made of wood or metal.

The solar collector works in the following way:

1. It is fixed on the roof of the building.

2. The sunlight passes through the glass cover and strikes the black plate.

3. About 50% of energy is reflected back onto the glass.

4. The glass then reflects it back onto the plate.

5. This heats the water in the tubes.

6. The heated water in the tubes is fed into the heating system of the building.

Since they can still supply heat even when it is already colder outside, flat plate collector are preferred choice today for solar water heating in households.

What is a Computer?

Computers are electronic machines which can accept data in a certain form, process the data and give the results of the processing in a specified format as information.

Three basic steps are involved in the process. First, data is fed into the computer’s memory. Then, when the program is run, the computer performs a set of instructions and processes the data. Finally, we can see the results (the output) on the screen or in printed form.

Information in the form of data and programs is known as software, and the electronic and mechanical parts that make up a computer system are called hardware. A standard computer system consists of three main sections: the central processing unit (CPU), the main memory and peripherals.

Perhaps the most influential component is the central processing unit. Its function is to execute program instructions and coordinate the activities of all the other units. In a way, it is the ‘brain’ of the computer. The main memory holds the instructions and data which are currently being processed by the CPU. The peripherals are the physical units attached to the computer. They include storage devices and input/output devices.

Storage devices (floppy, hard or optical disks) provide a permanent storage of both data and programs. Disk drivesare used to handle one or more floppy disks. Input devices enable data to go into the computer’s memory. The most common input devices are the mouse and the keyboard. Output devices enable us to extract the finished product from the system. For example, the computer shows the output on the monitor or prints the results onto paper by means of a printer.

On the rear panel of the computer there are several ports into which we can plug a wide range of peripherals – modems, fax machines, optical drives and scanners. These are the main physical units of a computer system, generally known as the configuration.

The main memory of a computer is also called ‘internal memory’, as distinct from any storage

available on disks. PCs make use of two types of main memory: RAM and ROM.

RAM stands for ‘ Random Access Memory’. It is called, that because the processor can find data in any cell or memory address with equal speed, instead of looking for the data in a sequential order.

The data in the RAM is volatile, so it is lost when the power is switched off. Therefore, if we want to use this data later on, we have to save it on disk. When running an application, the CPU finds its location in the storage device (e.g. hard disk) and transfers a temporary copy of the application to the RAM area.

ROM is an acronym for ‘Read Only Memory’, which implies that the processor can read and use the data stored in the ROM chip, but cannot put data into it. For this reason, it is also referred to as ‘firmware’. ROM chips have ‘constant’ information, including instructions and routines for the basic operations of the CPU. These are used to start up the computer, to read the data from the keyboard or to send characters to the screen.

SMART MATERIALS

Smart – or shape memory – materials are an invention that has changed the world of engineering. There are two types of such materials: metal alloys and plastic polymers. The metal alloys were made first and they are usually an expensive mixture of titanium and nickel.

Shape memory materials are called 'smart' because they react to changes in their environment, for example:

• plastics that return to their original shape when the temperature changes; One use is in
surgery where plastic threads 'remember' the shape of a knot, react to the patient's body
temperature and make themselves into stitches.

• metal alloys that have a 'memory' and can return to their original shape. They are used in medical implants that are compressed so they can be put inside the patient's body through a small cut. The implant then expands back to its original shape. More everyday uses are for flexible spectacle frames and teeth braces, solids that darken in sunlight, like the lenses in some sunglasses.

• liquid crystals that change shape and colour. These have been used in climbing ropes that
change colour if there is too much strain and weight on them.

The future of these materials and their possible uses is limited only by human imagination. One clever idea is that if cars were made of smart metal, a minor accident could be repaired by leaving the car in the sun!

The first reported steps towards the discovery of the shape-memory effect were taken in the 1930s. The nickel-titanium alloys were first developed in 1962–1963 by the United States Naval Ordnance Laboratory. Their remarkable properties were discovered by accident. A sample that was bent out of shape many times was presented at a laboratory management meeting. One of the technical directors decided to see what would happen if the sample was subjected to heat and held his pipe lighter underneath it. To everyone's amazement the sample stretched back to its original shape.

APPLICATION OF AUTOMATION AND ROBOTICS IN UNDUSTRY

Manufacturing is one of the most important application areas for automation technology. There are several types of automation in manufacturing.

1. Fixed automation, refers to automated machines in which the equipment configuration allows fixed sequence of processing operations. These machines are programmed to make only certain processing operations. They can’t easily switch from one product type to another. This form of automation needs high initial investments and high production rates. That’s why it is suitable for products that are made in large volumes. Examples of fixed automation are machining transfer lines in automobile industry, automatic assembly machines and certain chemical processes.

2. Programmable automation is a form of automation for producing products in large quantities ranging from several dozen to several thousand units at a time. For each new product the production equipment must be reprogrammed and changed over. This reprogramming and changeover take a period of non-productive time. Production rates in programmable automation are generally lower than in fixed automation, because the equipment is designed to facilitate product changeover rather than for product specialization. A numerical-control machine tool is a good example of programmable automation. The program is coded in computer memory for each different product type and the machine tool is also controlled by the computer program.

3. Flexible automation is a kind of programmable automation. Programmable automation requires time to reprogram and change over the production equipment for each series of a new product. This is lost production time, which is expensive. In flexible automation the number of products is limited, so the changeover of the equipment can be done very quickly and automatically by means of the computer. Flexible automation allows different products to be produced one right after another.

fixed automation – жесткая автоматизация, предполагающая выполнение операций в фиксированной/заданной последовательности

fixed sequence – заданная последовательность

initial investments – начальные инвестиции, вклады

production rate – темп производства

transfer lines – передаточные/транспортные производственные линии

assembly line – сборочный конвейер/линия

changeover – переключение, перенастройка

a numerical-control machine – станок с числовым программным управлением/станок с ЧПУ

flexible automation – гибкая автоматизация
