A team of scientists at Massachusetts Institute of Technology have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say. The phenomenon, described as thermopower waves, is such a new discovery that it’s … [Read more...]

electronics cooling in the automotive environment
Introduction By 2008 the electronics content of a typical consumer vehicle had grown to 20-25% of the total vehicle cost [1]. This content provides a wide range of functions and features for today’s driver. Some features such as the radio/audio system and instrument cluster are quite familiar and visible to the driver and have been mainstays in the automobile for many years. … [Read more...]
Carbon Nanotubes as High Performance Thermal Interface Materials
Introduction Because of substantial increases in the power density of electronic packages over the past few decades, thermal interface resistance can comprise more than 50% of the total thermal resistance in current high-power packages [1]. Unless advanced thermal interface materials (TIMs) that achieve order-of-magnitude improvements in performance quickly emerge in the … [Read more...]
