ARPA-E Projects to Develop New Technologies for High Performance Heat Exchangers, Components

The U.S. Department of Energy has announced $36 million in awards for 18 projects as part of the High Intensity Thermal Exchange through Materials and Manufacturing Processes (HITEMMP) program, as well as the final OPEN+ Cohort, High Temperature Devices. These project teams seek

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

Researchers find an Unusual way in Which a Material Conducts Heat when it is Compressed

In the latest wrinkle to be discovered in cubic boron arsenide, the unusual material contradicts the traditional rules that govern heat conduction, according to a new report by Boston College researchers in today’s edition of the journal¬†Nature Communications. Usually, when a material
