The tunable refractive index of the magnetic fluid (MF) is a unique optical property, which has attracted lot research interest in recent years. In this paper, method based on Fresnel reflection at fiber end face presented. Experimental measurements are carried out to investigate field (intensity and direction) temperature-dependent MF. For given concentration, with increase intensity, nMF increases gradually when H//Light, while decreases H⊥Light. effect temperature relatively insignificant...
Elevating the charging voltage could greatly promote energy density of lithium-ion batteries (LIBs) with LiNixMnyCozO2 cathodes, although challenges arise from severe parasitic reactions and rapid capacity decay at high voltage, especially for nickel-rich cathodes. Herein, by incorporating various useful functionalities into one single molecule, we rationally design synthesize a new class five-membered asymmetric cyclophosphamides as electrolyte additives to enable stable cycling...

When excited, 5.6-fold enhancement fields obtained as compared with purely resonance. It also found that for such coupling,...

Magnetic fluids are composed of ferromagnetic particles, surfactants, and a carrier liquid. For magnetic fluid when subjected to an external field, the nanoparticles tend form chain-like structures along direction thereby altering some their physical properties. The structure is simulated utilizing dissipative particle dynamics (DPD) method. A computational model established for particles. Comparative analysis different time integration methods reveals qualitative consistency between...
