Researchers at the Carnegie Institution in Washington, D.C. have discovered a new, efficient way to extract heat using ferroelectric crystals. The crystal materials exhibit an electrical polarization in the absence of an electrical field that can be reversed by applying an external electrical field, resulting in a significant temperature change. Ronald Cohen, staff scientist … [Read more...]
Researchers Develop Possible New Heat Dissipation Method with Cold Plasma Treatment
Researchers from the College of Materials Science and Engineering at Beijing University of Chemical Technology in China have determined a new method for enhancing heat dissipation in microelectronics based on research on plasma-treated h-BN fillers. According to results published by Professor Yonglai Lu and Tui Ji, a master of engineering at the Center of Advanced Elastomer … [Read more...]
Choosing Adhesives for Withstanding Thermal Cycling Stresses
Many engineers have traditionally designed bonding applications to withstand extreme temperatures using the idea that substrate materials and adhesives with similar coefficients of thermal expansion (CTE) will, at a given temperature, change size at the same rate. However, the difficulty of finding substrates and adhesives that have compatible CTEs and meet all application … [Read more...]
Research on Measuring Nanoscale Thermal Conductance May Increase Cooling Efficiency
A research team at the University of Illinois as Urbana-Champaign (UIUC) has developed a new system for examining and measuring nanoscale thermal conductance at the interface between two materials. The scientists believe that with further refinement, the system can be used to harvest electricity from waste heat, increase cooling efficiency of microelectronic devices and target … [Read more...]
Nanostructures May Solve Cooling Issues of Tiny Future Electronics
Researchers at several universities in the southern and western parts of the United States have recently made advances in one of the ongoing issues that has troubled the electronics industry for the past two decades: as electronic devices and equipment become increasingly smaller and more powerful, they generate more heat within a smaller amount of space and increase the … [Read more...]
