4.1.4 Read the text and explain what nanotechnology is. Nanotechnology

Nanotechnology is the engineering of functional systems at the molecular scale. Thus it’s the science of building tiny things. Today we usually make things by shaping materials – cutting, grinding*, milling**, etc. But in the future, we’ll be able to work on a smaller scale and build things atom by atom.

Today scientists can build nanowires – extremely strong tubes that are just four atoms wide. And when they have the manufacturing systems, they’ll be able to build anything we want – diamonds, water, food, robots, etc. We’ll be able to make all kinds of things smaller, lighter, cheaper, stronger, and smarter.

We are at the start of a technological revolution and nanotechnology will affect every part of our lives – cars, computers, medicine, energy supplies, food, clothes. It will offer better built, longer lasting, cleaner, safer products for home, for communications, for transportation, for agriculture, and for industry in general. And it will happen sooner than most people think. By 2010 you won’t be able to count the number of businesses using nanotechnology.

4.1.5 Mark the sentences True (t)/ False (f). Correct the wrong statements.

  1. Nanotechnology is the science of making large things.

  2. Nowadays scientists can’t build nanowires.

  3. In the nearest future we’ll be to make smaller, cheaper and safer products for all needs.

  4. Technological revolution won’t influence any sphere of our life.

  5. Nanostructures will be true only in 40-50 years.

4.1.6 Read the information about 4 generations of nanotechnologies given in the table. Give the examples of Participle II.

1st Passive nanostructures

( 1st generation products)

Materials designed to perform 1 task

~ 2000

  1. Dispersed and contact nanostructures, e.g.: aerosols

  2. Products incorporating nanostructures, e.g.: coatings, nanoparticle reinforced composites, nanostructured metals, polymers, ceramics

2nd Active nanostructures

For multitasking

~ 2005

  1. Bio-active, health effects, e.g.: targeted drugs, biodevices

  2. Physico-chemical active, e.g.: 3D-transistors, amplifiers, adaptive structures

3rd Integrated nanosystems

(with thousands of interacting components)

~ 2010

E.g.: guided assembling, 3D networking and new hierarchical architectures, robotics

4th Molecular nanosystems

(molecular manufacturing)

~ 2015-

2020

E.g.: molecular devices “by design”, atomic

design, emerging functions

4.1.7 Make Participle I and participle II of the following verbs. Translate them.

E.g. incorporate- incorporating (P1)-включающий, включая

incorporated (P2)-включенный

Describe, develop, design, perform, introduce, integrate, include, build, connect, limit, improve, formulate.

4.1.8 Make up 5 sentences with the participles from Ex. 5.7

4.1.9 Match the verbs in A with their synonyms in B.

A B

affect take away

perform pour out

resist form

shape carry out

remove oppose

spill influence

4.1.10 Use the verbs from 4.1.9 in the sentences below. Change the form where necessary.

  1. He has been ……surgery for 10 years.

2) I accidentally…… my drink all over him.

3) These stains will be difficult to……

4) This metal is able to……corrosion.

5) You can buy specially……bricks for an arch.

6) Nanotechnology in its advanced form will…… almost all industries and all areas of society.

4.1.11 Complete these predictions about nanotechnology. Use each verb in the list once.

construct perform

replace (with) store

clean up take

remove stop

resist wear

send

A Manufacturers will be able to construct cars from lightweight materials that are 50 times stronger than steel. Today’s two-ton Cadillac could weigh only 50 kg in the future.

The materials used to build cars will be able to……(1) scratches, dents, and rust (царапины, вмятины, ржавчина)

B We’ll be to……(2) trillions of bytes of information in a structure the size of sugar cube.

C Doctors will be able to……(3) broken human bones (кости) with artificial bones made with nanotechnology.

Nanorobots will be able to……(4) surgery. We’ll be able to……(5) pills(пилюли) containing nanorobots.

D We’ll be able to……(6) nanorobots up into space to rebuild the ozone layer. Other nanorobots will be able to……(7)pollutants from water and……(8) oil spills.

E Everyone will be able to……(9) computers and colour screens because they will be built into their clothes.

We’ll be able to……(10) our clothes from getting dirty by making them with stain repellent fabrics (ткани, устойчивые к пятнам)
