MODULE I NANOSCIENCE. NANOTECHNOLOGY AND NANOENGINEERING Focus: Introduction to Nanotechnology Grammar Focus: The Infinitive Skills Focus: Reading about the history of nanotechnology and its evolution; learning general vocabulary and terminology; developing speaking and writing skills UNIT 1. INSIGHT INTO THE SCIENCE OF NANOTECHNOLOGY Before you read 1. Master the active vocabulary: dimension – измерение, величина, объем diverse – иной, отличный, разнообразный, разный extension — распространение, предоставление conventional – обусловленный, стандартный, условный toapproach – приближаться, подходить assembly – общество, сбор assume –присваивать toassemble – подбирать, собирать, монтировать entities – сущность to evolve – развивать, раскрывать 2. Many words have been used to describe nanotechnology. Name four of the terms below that you think give the best description of nanotechnology. study, engineering, system, nanoscale, molecule, dimension, components, atomic and molecular scale, investigate, implications, nanoobjects, nanophotonics, entities, impact of nanomaterials, toxicity
3. Discuss the following questions in pairs or small groups. 1. What is nanotechnology? 2. What does nanotechnology deal with? 3. Which properties do materials hundreds of nanometers in size exhibit? 4. What are the applications of nanotechnology? 4. Read the text and say what new facts you have found. Overview of Nanotechnology Nanoscience is the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale. Nanoscience is not just the science of the small, but the science in which materials with small dimension show new physical phenomena, collectively called quantum effects, which are size-dependent and dramatically different from the properties of macroscale materials. Bulk materials (the ‘big’ pieces of materials) possess continuous (macroscopic) physical properties. The same applies to micron-sized materials (e.g. a grain of sand). But when particles assume nanoscale dimensions, the principles of classic physics are no longer capable of describing their behaviour (movement, energy, etc.): at these dimensions, the principles of quantum mechanics principles. Nanotechnology is defined thus: ‘Nanotechnology is the design, characterisation, production and application of structures, devices and systems by controlling shape and size at the nanometre scale.’ The nanometre scale is conventionally defined as 1 to 100 nm. One nanometre is one billionth of a metre (10-9 m). Nanoscience and nanotechnology deal with clusters of atoms of 1 nm in at least one dimension. For scale comparisons, 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 word nenos, meaning "dwarf." Scientists originally used the prefix just to indicate "very small," as in "nanoplankton," but it now means one-billionth, just as milli- means one-thousandth, and micro- means one-millionth. The story of nanotechnology begins in the 1950s and 1960s, when most engineers were thinking big, not small. This was the era of big cars, big atomic bombs, big jets, 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 (IС) in 1959 launched an era of electronics miniaturization.
As electronics engineers focused on making things smaller, engineers and scientists from other fields also turned their focus to small things - atoms and molecules. Usually the credit for inspiring nanotechnology goes to a lecture by Richard Phillips Feynman, a brilliant physicist. Feynman himself didn't use the word "nanotechnology"; in fact, only in the 1980s did this new field of study get a name – Nanotechnology. This new name was popularized by physicist K. Eric Drexler. Two main approaches are used in nanotechnology. In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control. Areas of physics such as nanoelectronics, nanomechanics and nanophotonics have evolved during the last few decades to provide a basic scientific foundation of nanotechnology. Comprehension check 5.

Read the text and answer the questions below. Nanoengineering Nanoengineering is one field of nanotechnology. Nanotechnology is an umbrella term that encompasses all fields of science that operate on the nanoscale.* A nanometer is one billionth of a meter, or three to five atoms in width. It would take approximately 40,000 nanometers lined up in a row to
equal the width of a human hair. Nanoengineering concerns itself with manipulating processes that occur on the scale of 1-100 nanometers. The general term, nanotechnology, is sometimes used to refer to common products that have improved properties due to being fortified with nanoscale materials. One example is nano-improved tooth-colored enamel, as used by dentists for fillings.* The general use of the term “nanotechnology” then differs from the more specific sciences that fall under its heading. Nanoengineering is an interdisciplinary science that builds biochemical structures smaller than bacterium, which function like microscopic factories.* This is possible by utilizing basic biochemical processes at the atomic or molecular level. In simple terms, molecules interact through natural processes, and nanoengineering takes advantage of those processes by direct manipulation. Nanoengineering, in its infancy, has seen some early successes with using DNA as a catalyst to self-assemble simple structures. In 2006 a Brown University research team was able to grow zinc oxide nanowires of approximately 100-200 nm in length by fusing snippets of synthetic DNA to carbon nanotubes.* DNA, nature’s manual for creating matter from the bottom up, is of particular interest in the field of nanoengineering. By assembling specific DNA code a nanoengineer can set up the conditions for the genetic code to perform tasks that result in the biochemical assembly of nanomaterials. Comprehension check 5.
