Intertronics now offers CircuitWorks’ syringe-packaged conductive greases, which provide electric and/or thermal conductivity for a range of applications. CircuitWorks’ new silicone-free heat sink grease will not harden or dry out while offering excellent thermal conductivity and dielectric properties. It is non-corrosive and exceeds ML-C-47113 for thermal conductivity, … [Read more...]
Controlling Thermal Conductivity to Improve Energy Storage
Researchers at the University of Illinois at Urbana-Champaign have experimentally shown for the first time that the thermal conductivity of lithium cobalt oxide (LixCoO2), a material used in the cathodes of lithium-ion batteries, can be reversibly electrochemically modulated over a significant range. Many technologies require control over the flow of heat through materials in … [Read more...]
Built-in Heat Spreading for Efficient Thermoelectric Cooling of Concentrated Heat Loads
Jeff Hershberger, Robert Smythe, Xiaoyi Gu and Richard F. Hill Laird Technologies, Inc. INTRODUCTION Thermoelectric cooling is an active thermal management technique. A thermoelectric cooler (TEC) has two circuit boards which are typically Al2O3 plates with copper circuit traces attached to them and semiconductor elements soldered between them. TECs are now available … [Read more...]
Scientists Achieve First Measurement of Moly’s Thermal Conductivity
Scientists at the National Institute of Standards and Technology’s Physical Measurement Laboratory have succeeded in measuring the thermal conductivity for the first time of an ultra-thin material that is expected to play a major role in the developing field of nanoelectronics. Molybdenum disulfide, also known as molybdenite or “moly” for short, is a 2D material that measures … [Read more...]
New Thermoelectric Material May Boost Development of Green Technologies
New material properties discovered by researchers at the University of Miami may impact ongoing research into thermoelectric materials, which are useful in power generation, energy detection and refrigeration and cooling. Lead author Joshua Cohn, professor and chairman of the UM Department of Physics, and his colleagues report new properties of a metal known as lithium … [Read more...]
