The electromagnetic (EM) wave absorption properties of 2-mm-thick silicon carbide nanowire (SiCNW)−epoxy composites were studied in the range 2−40 GHz using a free-space antenna-based system. 35 wt % SiCNW exhibited dual-frequency EM absorptions −31.7 and −9.8 dB at 8.3 27 GHz, respectively. minimum reflection loss −32.4 was achieved 31.1 for containing 25 SiCNW. A study mechanism suggests combination electric conductance caused by network-like SiCNWs resin matrix relaxation polarization...
Rechargeable lithium metal batteries are next generation energy storage devices with high density, but face challenges in achieving safety, and long cycle life. Here, a novel nonflammable ionic-liquid (IL) electrolyte composed of 1-ethyl-3-methylimidazolium (EMIm) cations high-concentration bis(fluorosulfonyl)imide (FSI) anions, sodium bis(trifluoromethanesulfonyl)imide (NaTFSI) as key additive reported. The Na ion participates the formation hybrid passivation interphases contributes to...
Graphene is expected to enable superior corrosion protection due its impermeability and chemical inertness. Previous reports, however, demonstrate limited inhibition even enhancement of graphene on metal surfaces. To the reliable complete passivation, origin low efficiency was investigated. Combining electrochemical morphological characterization techniques, nanometer-sized structural defects in vapor deposition grown were found be cause for passivation effect. Extremely fast mass transport...
