Tunneling-induced negative permittivity is attributed to the low frequency plasmonic state in tunneling networks, where nickel nanoparticles are still isolated geometrically but connected electrically.
Carbon-based composites have shown excellent electromagnetic wave-absorption properties. In this work, an extremely facile and green method was developed to prepare Fe@Fe3C/C nanocomposites by carbonizing the bulrush impregnated with Fe(NO3)3 solutions. The core–shell Fe@Fe3C generated from carbothermal reductions interfacial reactions. minimum reflection loss exceeded −50 dB absorbers thickness almost no more than 2.00 mm. widest absorption bandwidth up 4.57 GHz a only 1.43 Meanwhile,...
In order to analyze the bearing wear in spindle system considering different speed and load conditions, a four-bearing was investigated. Two working Case I II, are considered. condition has lower higher external loads preload than II condition. Based on Archard model, new depth model of angular contact ball is presented which takes into account influence lubrication wear. The depths inner outer raceways for bearings calculated based motion parameters elements obtained by model. effects...
Herein, the conception of 2.5D metamaterial is proposed. The basic idea to build “3D” by stacking 2D metasurfaces layer‐by‐layer. In this design, trapezoidal prism units (3D) built up a series rectangle (2D) together. This means, in metamaterial, any kind 3D structure with complex geometrical shape can be easily controlling each layer, which provide new way for fabrication units. Furthermore, paper chosen as substrate because interconnected lignocellulosic microfibers will not only bring...
