New analytical technology reveals 'nanomechanical' surface traits
West Lafayette IN (SPX) Sep 01, 2014
A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. This new technique, called nanomechanical Raman spectroscopy, reveals information about how heating and the surface stress of microscale structures affect their mechanical properties. Researchers have discussed the merits of surface-stress influence on mechanical properties for d ... read more
