Microscopic cracks spoil the transparency of glass, nano-researchers find
A fundamental discovery about the behavior of cooling glass could have a significant impact on the glass- and plastic-making industries, say researchers at Lehigh University. Himanshu Jain says the breakthrough was made possible by a combination of nanoscopic science and an old-fashioned kitchen recipe. When molten glass is blown rapidly to make articles of desired shape, Jain's group found, its outermost surface, measuring a few nanometers in thickness, sustains microscopic fractures when it comes into contact with air.
