Thermal insulation material is a critical part of the thermal protection system (TPS) of hypersonic vehicles. Recently, high-entropy ceramics have attracted great attention in thermal insulation for their low thermal conductivity due to the scattering of phonons by multi-components and distorted lattices.

Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effectIntense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly, causing an ultrafast perturbation of the magnetic order.
