Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
Electronic sensors built into cartons(纸盒)may make it easier to tell when it’s time to throw out rotten milk or orange juice. And that’s just the start. At least that’s the goal for researchers working on putting electronics into paper. They’re trying to figure out how to combine the flexibility, low-cost and recyclability of paper with the information-carrying ability of electronics.
Daniel Torbjork, a physics graduate student in Finland, has been working on the problem. He’s published a review of the field in the journal Advanced Materials.
Much research has been focused in this area. While most electronic applications require patterned conducting structures, conductive paper could be used in applications such as energy storage devices, sensors, electric heaters and others, according to Torbjork.
“You could even have some interactive functions in magazines,” Torbjork said, “You could put a simple game in a package. If you want a touch screen, press a button and then something happen. Sensors in paper could tell us when something has gone bad.”
Additional applications, such as information storage and security paper, have been suggested for magnetic papers containing magnetite. In Massachusetts, researchers have figured out how to post a video of such a device put into a paper airplane.
German researchers have also put electronic chips in paper bank notes to defend counter-feiters(造伪币者). Paper is a good material but printing electronics also requires low-cost manufacturing. As many US and European paper makers lose market share to cheaper paper from China, these big paper companies are looking for added value products. That’s where electronic paper devices could make a difference.
“The major obstacles are paper’s large surface roughness and chemical impurities.” Torbjork says. But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
“I don’t think it’s going to happen.” said Roy Horgan. “You need a conductive surface. It could be 10 years out. What we are looking for are solutions that you can commercialize today.”
Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells(光电)that can capture electricity from the sun. In the meantime, using paper to conduct electricity is still a “blue-sky” project.
“I would love to see someone prove me wrong, because that means that it’s actually happening.” Horgan said. “If someone comes up with conductive paper, then that’s a very interesting technology.”
1.Putting electronics into paper will ________.
A. cut the cost and impurity of paper
B. depend on flexible conductive structure
C. help consume rotten milk or orange juice
D. combine the advantages of paper and electronics
2.Paragraphs 4 to 7 mainly talk about the ________ of the conductive paper.
A. practical use B. theories
C. structures D. design process
3.Some paper makers welcome the new technology probably because it will ________.
A. put an end to fake money B. make the paper smoother
C. add more value to paper D. improve the printing technology
4.From the passage, we know that Roy Horgan ________.
A. has a burning desire to make a great profit
B. showed much interest in Solar Print industry
C. is not confident about the conductive paper
D. started a “blue-sky” project to study paper

高三英语单项填空简单题查看答案及解析
Buildings can become greener. They can use more recycled steel and can be built in off-site factories,greatly reducing lorry journeys. But no other building material has environmental credentials(认证)as exciting and overlooked as wood.
The energy required to produce a laminated(复合的)wooden beam is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing,wooden buildings contribute to negative emissions by storing the stuff. When a mature tree is cut down,a new one can be planted to replace it,capturing more carbon. After buildings are pulled down,old beams and panels are easy to recycle into new structures. And for improving older buildings to be more energy efficient,wood is a good insulator(绝缘体),A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium one.
A race is on to build the world's tallest fully wooden skyscraper. But such buildings are still uncommon. Industry disunity,cut-throat competition for contracts and low profit margins(差额)mean that most building firms have little money for greener construction methods beyond what regulation requires
Governments can help urge the industry to use more wood,particularly in the public section. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be changed to take account of the emissions that exist in materials. This would favour wood as well as novel ways of producing other materials.
Construction codes could be adjusted to make building with wood easier. Here the direction of travel is wrong. Britain,for instance,is banning the use of wood on the outside of tall buildings after 72 people died in a tower fire in London in 2017.That is a nonsense. Grenfell Tower was covered in aluminium and plastic,not wood. Modern cross-laminated wood panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world's buildings into line.
1.What's the text mainly about?
A.Wood is the first choice for green buildings.
B.The public section makes good use of wood.
C.Building companies cannot afford greener construction.
D.Steel can reduce the environmental costs of buildings.
2.What does Paragraph 2 focus on?
A.Origins of wood structures.
B.Advantages of wood for building.
C.Reasons for green window frames.
D.Differences between steel and wood
3.Which of the following will discourage greener construction?
A.The races of wooden skyscrapers. B.Strict regulations on materials.
C.The push of the government. D.Fierce industry competition.
4.What can be inferred from the text?
A.Wood is to blame for a big building fire.
B.Britain will lift the ban of using wood on the outside wall.
C.Building with wood is facing an unfavorable situation.
D.The environmental costs of buildings rely on carpentry.

Years ago people could hardly accept the ideas of a woman’s being a doctor. In order to get into medical school in 1847, Elizabeth Blackwell was asked to keep it a secret that she was a woman. This was contrary to her beliefs, and she refused to do it. After entering medical school, Elizabeth often had to summon all her courage to free the unkindness of teachers and classmates. By her great efforts, she was able to complete her studies. Many people came to her graduation just to have a look at a woman doctor. Doctor Blackwell soon found that most people were not as ready as to go to a woman doctor. She had to struggle to make a living. Then came the great day when she was offered a job as a doctor in a hospital. She did so well that she was asked to organize a new hospital and medical college. The United States can now be proud of thousands of women doctors.
1.How do you think Elizabeth was treated in the medical school?
A. Kindly. B. Unfairly.
C. Normally. D. Cruelly.
2.Many people came to see Elizabeth when she graduated ________.
A. because they wanted to congratulate her on being a doctor
B. but they didn’t believe she would be famous in the future
C. because they wanted to find out the secret of her success
D. but they weren’t sure that she could manage to finish her schooling
3.When she was at the medical school, Blackwell ________.
A. had to pretend to be a boy student in class
B. was discouraged by the others’ critical looks
C. felt sorry that she was a woman
D. made great effort to do well in her lessons

A. she was not right for the job and had to struggle for a living
B. she must organize a new hospital and medical college for women
C. few people were willing to go to a woman doctor
D. most people were ready to go to a woman doctor
