Space and time dynamical heterogeneity in glassy relaxation. The role of democratic clusters
(IOP Publishing, 2009-05)
In this work we review recent computational advances in the understanding of the relaxation<br />dynamics of supercooled glass-forming liquids. In such a supercooled regime these systems<br />experience a striking dynamical ...
Contributions of Dipolar Relaxation Processes and Ionic Transport to the Response of Liquids to Electrical Perturbation Fields
(AMER CHEMICAL SOC, 2011)
The objective of this work was to study the influence of small variations in the chemical structure on the molecular dynamics of liquids using as models bis(cyclohexylmethyl) 2-methyl- and dicyclohexyl 2-methylsuccinate. ...
Influence of the fine structure on the response of polymer chains to perturbation fields
(AMER CHEMICAL SOC, 2006)
The relaxation behavior of poly(3-methylbenzyl methacrylate), poly(3-fluorobenzyl methacrylate), and poly(3-chlorobenzyl methacrylate) was thoroughly studied by broadband dielectric spectroscopy with the aim of investigating ...
Effects of thermal treatment on phase transitions and on the mechanical relaxation in poly(vinylidene fluoride)
(2002-12-01)
This work reports on the effects from thermal treatment in poly(vinylidene fluoride), PVDF, obtained with differential scanning calorimetry (DSC) and dynamic thermal analysis (DMA) measurements. It is shown that in successive ...

Spin-relaxation time in the impurity band of wurtzite semiconductors
(American Physical Society, 2017-09-18)
The spin-relaxation time for electrons in the impurity band of semiconductors with wurtzite crystal structure is determined. The effective Dresselhaus spin-orbit interaction Hamiltonian is taken as the source of the spin ...
THERMAL EFFECTS ON THE STRUCTURE AND RELAXATION PROPERTIES OF POLY(MONOCYCLOPENTYL ITACONATE)
(HUTHIG & WEPF VERLAG, 1995)
The effect of thermal treatment and subsequent chemical structural modifications on the viscoelastic and dielectric properties of PMCPI (poly(monocyclopentyl itaconate)) was studied. The low temperature relaxation ...
Retarded Green's-Function Calculation of Magnetic Resonance Relaxation Time TI for Rotating Molecules or Atomic Groups in Solids

Controlling the dominant magnetic relaxation mechanisms for magnetic hyperthermia in bimagnetic core-shell nanoparticles
(Royal Society of Chemistry, 2019-02)
We report a simple and effective way to control the heat generation of a magnetic colloid under alternate magnetic fields by changing the shell composition of bimagnetic core–shell Fe3O4/ZnxCo1−xFe2O4 nanoparticles. The ...
