• Researchers describe unusual ways that material conducts heat when compressed

  Researchers from Boston College (Mass.) revealed that, unlike typical materials, when cubic boron arsenide is compressed it does not become a better conductor of heat, but instead thermal conductivity initially improves before deteriorating. details>>

• Thermally-painted metasurfaces produce perfect light absorbers for high-tech applications

  Researchers from Case Western University (Cleveland, Ohio) demonstrated that heating a metal to create a vibrant color, which remains the same color regardless of the viewing angle, creates nanostructures on the surface that acts as a perfect light absorber. details>>

• Scientists demonstrate that electrically-heated silicate glass defies long accepted law in physics

  Researchers at Lehigh University (Bethlehem, Pa.) demonstrated that applying a direct current field across common silicate glass reduces its melting temperature and enables the glass to be shaped with greater precision than heat alone, according to a report from the university. details>>

• Quantum model for achieving ground-state cooling demonstrated using nitrogen vacancy centers

  Scientists from the Center for Nanoscale Materials at Argonne National Laboratory (Lermont, Ill.) presented a quantum model for ground-state cooling in low-frequency mechanical resonators and demonstrated that cooperativity and entanglement are critical to enhancing the cooling figure of merit. details>>

• Running an LED in reverse could be new solid-state cooling technology for microprocessors

  Researchers at the University of Michigan (Ann Arbor, Mich.) discovered that running a light-emitting diode (LED) with the electrodes reversed could cool a second device that was nanometers away, according to a report from the university. details>>

• Researchers create new material for supercapacitors with more than double the energy density

  Researchers from Tohoku University in Sendai, Japan collaborated with supercapacitor manufacturer TOC Capacitor Co. to create a new material from graphene mesosponge, which contains nanoscale pores, that could be used to build supercapacitors with higher voltage and better stability than those built from conventional materials. details>>

• Strain engineering can be used to change the thermal properties of semiconductor materials

  Researchers from the Massachusetts Institute of Technology (MIT) in Cambridge, Mass., the Skolkovo Institute of Science and Technology (Skoltech) in Moscow, Russia, and Nanyang technological University in Singapore discovered that applying strain to a semiconductor or crystalline material deforms the order of its atom and impacts its electrical, optical, and thermal properties. details>>

• Researchers unlock secrets behind heat transport in black phosphorous nanoribbons

  Scientists from the Agency for Science, Technology and Research (A*STAR) Institute of Materials Research and Engineering in Singapore discovered why heat moves twice as fast in the wrinkle of a black phosphorous nanoribbon as it does across the wrinkle. details>>

• Physicists create the first electron liquid at room temperature, paving way for more study

  Scientists at the University of California, Riverside (UCR) created the first electron liquid at room temperature by bombarding a sandwich of ultrathin semiconductor molybdenum ditelluride layered between graphene with superfast, powerful lasers. details>>

• Researchers create thermoelectric device from cellulose to convert waste heat into electricity

  Researchers at the Institute of Materials Science of Barcelona, Spain (ICMAB-CSIC) created a new thermoelectric paper from cellulose and carbon nanotubes to convert waste heat into electricity for IoT sensors, according to a report from the institute. details>>
