Electrical and thermal conductivity of CNT/alumina‐nanocomposite ceramics

open access: yesInternational Journal of Ceramic Engineering & Science, 2023
In the present work, carbon nanotube (CNT)‐reinforced alumina nanocomposite ceramics were investigated about their electrical and, for the first time in such detail, thermal conductivity. Therefore, two different alumina powders with varying CNT‐contents

Geodynamo Conductivity Limits

open access: yesGeophysical Research Letters, 2019
In a metal, as in Earth's core, the thermal and electrical conductivities are assumed to be correlated. In a planetary dynamo this implies a contradiction: that both electrical conductivity, which makes it easier to induce current and magnetic field, and
