"avoids complex, energy-intensive, unidirectional freezing... discarded egg white precursor, self-assembly (salting-out protein)... yields directional 1–7 µm macroporous channels enhancing impedance matching/ EM wave attenuation when EM waves propagate parallel to channels... WC1-x nanoparticles formed (tunable) during pyrolysis/ uniformly dispersed on carbon matrix, improving energy dissipation... record minimum reflection loss, wide absorption bandwidth... radar stealth, chip anti-interference"
