Technique Reveals Glass Surface Damage at the Nanolevel

A spectroscopy technique has enabled the study of nanolevel imperfections in the surface of glass. The process could lead to improvements in glass products such as electronic displays and vehicle windshields, according to a team of international researchers that aims to produce a technique capable of detecting the kind of structure change that takes place around nanolevel indentations on the surface of glass. Such an approach would shed light on the properties that determine the strength of glass. One of the main focuses of Penn State professor of chemical engineering Seong Kim’s group is the study of glass surfaces, particularly their structure and durability in terms of their mechanical and chemical properties.
