Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

Focusing on metallic glasses as model systems, we review the features and mechanisms of
the β-relaxations, which are intrinsic and universal to supercooled liquids and glasses, and …

After a short historical review concerning measurements of the dielectric response of simple
glass formers, we discuss the complex dielectric permittivity ε ̂ ν above and below the glass …

The local dynamics of 1, 4 polybutadiene below and above the merging of the α and β
relaxations have been investigated by combining neutron spin echo (NSE) and dielectric …

We report on dielectric susceptibility measurements for the glass-forming systems toluene
and 1-propanol, both of which exhibit slow secondary relaxation (Johari β-process). We …

We study the Johari–Goldstein β process of organic glass formers by one-(1D) and two-
dimensional (2D) H 2 nuclear magnetic resonance (NMR). In particular, we compare …

The dielectric properties of biaxially stretched polyethylene terephthalate (PET) films of
thickness and 68% degree of crystallinity were investigated by means of dielectric relaxation …

We present a united atom force field for simulations of 1, 4-polybutadiene based on ab initio
quantum chemistry calculations on model molecules. The geometries and energies of …

Intrinsic mobility of the glassy state is known as Johari–Goldstein (JG)-relaxation. Its source
is either rotational and translational motions of a small number of molecules or small-angle …

Nuclear magnetic resonance and electrical conductivity measurements are conducted to
study the dynamics of the ionic diffusion process in the crystalline ionic conductor Li 0.5 La …
