Mitigating hypersonic heat barrier via direct cooling enhanced by leidenfrost inhibition. [PDF]

open access: yesNat Commun
Heat barrier, the unrestricted increase in airplane or rocket speeds caused by aerodynamic heating, which—without adequate provisions for cooling the exposed surfaces—can lead to the loss of a hypersonic vehicle’s reusability, maneuverability, and cost ...

Lessons From Deep Eutectic Solvents to Design High Entropy Electrolytes for Electrochemical Energy Storage. [PDF]

open access: yesChemSusChem
The aim of this perspective is demonstrating how the correspondence between deviations from ideality and solvation structure observed in deep eutectic solvents may help for designing the specific composition of high entropy electrolytes that maximize performance in electrochemical energy storage systems.

Materials design for hypersonics. [PDF]

open access: yesNat Commun
AbstractHypersonic vehicles must withstand extreme conditions during flights that exceed five times the speed of sound. These systems have the potential to facilitate rapid access to space, bolster defense capabilities, and create a new paradigm for transcontinental earth-to-earth travel.

Laser ablation behavior of C/SiC composites subjected to transverse hypersonic airflow

open access: yesCorrosion Science, 2021
Laser ablation behaviors of C/SiC composites were examined in a hypersonic wind tunnel. Parallel laser ablation tests under static air were also conducted, and the ablation behaviors of these two conditions were compared.
