Frequency-dependent shear and bulk viscosity of aqueous and non-aqueous lithium battery electrolytes

Transverse ultrasound was used to examine the frequency-dependent shear viscosities of three lithium bis(trifluoromethanesulfonyl)imide-based electrolytes: aqueous, non-aqueous, and hybrid aqueous-organic solutions. Frequency-dependent bulk viscosities of two of the electrolytes...

Molecular dynamics simulation study on sound dispersion and acoustic relaxation of water in wide temperature and density ranges

Frequency-dependent complex shear and bulk viscosities of water from supercooled to supercritical conditions were evaluated by means of molecular dynamics simulations in order to understand the behavior of sound dispersion in the nm−1 wavenumber region. In the liquid-like density...
