Nanotechnology, according to its fans,
will jump-start a new industrial revolution with molecular-sized structures as
complex as the human cell and 100 times stronger than steel. The new technology
transforms everyday products and the way they are made by manipulating atoms so
that materials can be shrunk, strengthened and lightened all at once. To date
only modest nanotech-based products—such as stain-resistant fabrics and fresh
food packaging—have entered the market, but some scientists predict
nanotechnology will eventually be the only game in town. "It will be a
ubiquitous technology," said George Stephanopoulos, professor of chemical
engineering at the Massachusetts Institute of Technology. He echoes other
nanotech supporters who say industrial countries are already sliding toward its
use in every aspect of manufacturing. A. How to prolong the 10 to 20 years’ time. B. How to eliminate the public’s prejudice. C. How to solve the problem of big and small. D. How to get enough manpower and money. 我来回答: 提交
