This finding contradicts theoretical expectations of melting points for small clusters, which are expected to fall as cluster size is reduced and that nanoscopic lumps of many materials should be liquid at room temperature. This research is thought to have implications for nanotechnology and material science, such as the possibility that established theory is unable to predict whether or not nanoscopic clusters sinter at low temperatures. [ Article from Physics News Update ] · Compound Semiconductor featured the Rensselaer Lighting Research Center's (LRC) development of non-invasive methods for measuring the lifetimes of LED lighting systems in the October issue. LEDs currently have no comprehensive performance record. Nadarajah Narendran, director of research at the LRC, and his students Eugene Hong and Yimin Gu, have completed two studies that define new methods of determining junction temperature in LED systems -- see "A Non-Contact Method for Determining Junction Temperature of Phosphor-Converted White LEDs," Y Gu and N Narendran, 2003, Proc. SPIE 5187 (in press); and "A Method for Projecting Useful Life of LED Lighting Systems," E Hong and N Narendran, 2003, Proc. SPIE 5187 (in press). These studies focused on finding alternative methods for determining junction temperature, which could then potentially lead to predictions of LED system life. The LRC group is now reportedly working to identify the relationship between junction temperature and the degradation rate for LEDs, with future studies developing data that would show LED degradation rates at various junction temperatures.
