“…On the one hand, 1D nanostructures can effectively extend the transmission path of electromagnetic (EM) waves and enhance attenuation ability. 12 On the other hand, the high aspect ratio is beneficial to constructing effective conductive networks for the interconnection between each other to further enhance the dielectric loss. 13 Moreover, the interpenetrating conductive networks are beneficial for the generation of microcurrent as well as multiple reflection and scattering of EM waves.…”

Herein, an efficient one-dimensional (1D) N-doped Co/C nanotube absorber was designed by a cobalt source and solvent ratio comodulation strategy. First, we explored the influences of different cobalt sources (CoCl 2 , Co(OAc) 2 , Co-(NO 3 ) 2 , and CoSO 4 ) on the morphology and microwave absorption (MA) property, which showed that CoCl 2 facilitated the formation of nanotubes with a relatively uniform diameter and length. Notably, the Co/C nanotubes displayed an ultrawide effective absorption bandwidth (EAB) of 6.885 GHz at 2.2 mm when the filling ratio was only 8 wt %. Then, by adjusting the solvent ratio of isopropanol (IPA) and water, Co/C showed a strong absorption of −44.51 dB with an EAB of 5.44 GHz at 2.35 mm. The outstanding MA performance is ascribed to the synergistic effect of dielectric and magnetic components, which is conducive to optimizing the impedance matching, thus broadening the EAB. In addition, the 1D nanostructure is good for constructing three-dimensional (3D) conductive networks and enhancing conductive loss. Since Co nanoparticles are wrapped in carbon nanotubes (CNTs), the confinement effect can effectively prevent the agglomeration of ferromagnetic nanoparticles, adjusting the MA performance. It is worth mentioning that the maximum Radar cross section (RCS) value of Co/C can be reduced by 28.8 dB m 2 . Furthermore, the RCS values are all lower than −10 dB m 2 from −90 to 90°and the minimum RCS value can reach −46.8 dB m 2 . This work provides a strategy for designing lightweight MA absorbers with strong RL and ultrawide EAB.

“…Recently, some of us analyzed the dynamic susceptibility of curved permalloy nanotubes [ 51 ] and permalloy wire-tube nanostructures [ 52 ]. However, to the best of our knowledge, there are no studies that systematically investigate the static and dynamic properties of Fe 3 O 4 nanotubes, despite the high aspect ratio being conducive to electron conduction and further increasing the conduction loss capability [ 53 ].…”

In this paper, our objective was to investigate the static and dynamic magnetic properties of Fe3O4 nanotubes that are 1000 nm long, by varying the external radius and the thickness of the tube wall. We performed a detailed numerical analysis by simulating hysteresis curves with an external magnetic field applied parallel to the axis of the tubes (along the z-axis). Our findings indicate that nanotubes with an external radius of 30 nm exhibit non-monotonic behavior in their coercivity due to a change in the magnetization reversal mechanism, which was not observed in nanotubes with external radii of 80 nm. Additionally, we explored the dynamic susceptibility of these nanotubes and found that the position and number of resonance peaks can be controlled by manipulating the nanotube geometry. Overall, our study provides valuable insights into the behavior of Fe3O4 nanotubes, which can aid in the design and improvement in pseudo-one-dimensional technological devices.
