... and an absorbing media (like aerogel) as it influences thermal conductivity measurements made by the transient hot-wire method. They claim that the transient hot-wire technique is accurate for materials like aerogel if the extinction coefficient exceeds 5000 m −1 with temperatures near 25  ° C However, our hot...
