Design and Validation of Multilayered Thermal Emitter Using Machine Learning

Scientists designed a multilayered metamaterial that realizes ultra-narrowband wavelength-selective thermal emission by combining the machine learning (Bayesian optimization) and thermal emission properties calculations (electromagnetic calculation). The joint team then experimentally fabricated the designed metamaterial and verified the performance. These results may facilitate

Controlling Thermal Conductivity of Polymers with Light

Polymers are regularly used as thermal insulators for everything from keeping beverages hot to keeping sensitive electronics cool. In some cases, polymers can even be used as thermal conductors to enable efficient heating or cooling. In a new study, researchers at the

Teijin to Acquire Thermoset Manufacturer Renegade Materials

Teijin Ltd. has agreed to acquire Renegade Materials Corp. (Renegade), a leading North American supplier of highly heat-resistant thermoset prepreg for the aerospace industry. Renegade will become a wholly-owned subsidiary of Teijin. The shares of Renegade will be purchased by Teijin Holdings

Superinsulating Aerogel Resists Mechanical and Thermal Shocks

Aerogels are exceptionally lightweight, composite materials containing more than 99 percent air. They can withstand high temperatures and are resistant to many chemicals. Most aerogels studied so far, however, are made from ceramic materials, such as silica, alumina and silicon carbide, and

Henkel Expands Bergquist Gap Pad Portfolio

Henkel Corp. has added two ultra-low modulus Bergquist Gap Pad thermal interface materials (TIMs) to its line of high compliance thermal management products. Bergquist Gap Pad TGP 6000ULM and Bergquist Gap Pad TGP 7000ULM have been formulated with an advanced resin platform

Black Phosphorus Wrinkles Take the Heat

Single atomic sheets of black phosphorus are attracting attention for their potential in future electronics applications. A*STAR researchers have now completed experiments at the nanoscale to unlock the secret of this material’s remarkable directional heat transport properties. Black phosphorus has a layered

Charting a Map for Determining Negative Thermal Expansion

Most materials exhibit some degree of thermal expansion – that is, they expand when heated and shrink when cooled. Concrete structures are designed with joints that allow for this expansion and contraction, to prevent cracking and structural failure. Some materials, however, exhibit
