U.S. researchers have developed a new "nanoglue" that's 100,000 times thinner than a human hair and gets stronger at high temperatures. The researchers say this nanoglue can be used to make extremely thin computer chips:
"It is really mind-boggling to think about a single layer of molecules improving the adhesion of something," said materials science researcher Ganapathiraman Ramanath, whose work appears in the journal Nature.
"Our work shows the possibility of having organic-based nanolayers that are about a 1,000 times thinner than the thinnest organic-based glues," he said.
Similar toughness has been shown using layers as thin as a millionth of a meter, but never before with a thickness of only 1 nanometer, which is a billionth of a meter.
"This is a single layer of molecules that are organized like soldiers," Ramanath said in a telephone interview. The glue chain lines up in very orderly fashion all on its own.
"Nature does most of it for you," Ramanath said. "You just have to put the right thing on the top and the right thing on the bottom, and it will work."
