WebCombining broadband impedance spectroscopy, differential scanning calorimetry, and nuclear magnetic resonance we analyzed charge and mass transport in two polymerized ionic liquids and one of their monomeric precursors. In order to establish a general procedure for extracting single-particle diffusivity from their conductivity spectra, we … WebRayleigh–Ritz or Ritz Method. The Rayleigh–Ritz method enables one to reduce an infinite number of degrees-of-freedom of a system into a finite number, which makes analysis possible and easier. The method relies on the approximation of the possible deformation shapes of the system, following the basic idea beyond Rayleigh's principle.
