CHICAGO (Reuters) - A cheap glue that gets stronger at high temperatures might be useful around the house, but make it 100,000 times thinner than a human hair and you have nanoglue, a sticky substance that could help make extremely tiny computer chips, U.S. researchers said on Wednesday. Developed by researchers at Rensselaer Polytechnic Institute in Troy, New York, nanoglue is made from ultrathin materials that are already commercially available. "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....
