DIELECTRIC RELAXATIONS IN POLY(THIOCARBONATES)
(JOHN WILEY & SONS INC, 1994)
The dielectric absorptions observed on six poly (thiocarbonates) (PTC) containing different substituents in the interphenylic carbon atom are subjected to a study. The a relaxation process associated with the glass transition ...
Paramagnetic nanoparticles as potential MRI contrast agents: characterization, NMR relaxation, simulations and theory
(Springer, 2012-12)
Object Paramagnetic nanoparticles, mainly rare earth oxides and hydroxides, have been produced these last few years for use as MRI contrast agents. They could become an interesting alternative to iron oxide particles. ...
Use of water spin-spin relaxation rate to probe the solvation of cyclodextrins in aqueous solutions
(Amer Chemical SocWashingtonEUA, 2008)
Determining the heterogeneity in time of the dynamics within a slowly relaxing region of a supercooled liquid: Role of sharp relaxation events
(American Physical Society, 2009-08-26)
Supercooled liquids have been shown to be dynamically heterogeneous with different regions of the system presenting dynamics that vary from each other even by orders of magnitude. Computer simulations have confirmed such ...
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 ...
Spin relaxation near the metal-insulator transition: Dominance of the Dresselhaus spin-orbit coupling
(American Physical Society, 2012-01)
We identify the Dresselhaus spin-orbit coupling as the source of the dominant spin-relaxation mechanism in the impurity band of a wide class of n-doped zinc blende semiconductors. The Dresselhaus hopping terms are derived ...
L-Carnitine supplementation impairs endothelium-dependent relaxation in mesenteric arteries from rats
(Informa Healthcare, 2014-07-01)
L-Carnitine (L-Car) is taken as fat burner. The risks of L-Car supplementation for the cardiovascular system are unclear. We evaluated the relaxing responses of the mesenteric and aorta rings from rats after four weeks of ...
Deep multilayer relaxations on the Al(001) surface: Ab-initio all-electron calculations
(American Physical Society, 2007-04)
The multilayer relaxations of pure Al001 surface were theoretically analyzed using ab initio all-electron calculations. Big slabs 23 atomic layers+20 vacuum layers were needed to capture the deep pattern of multilayer ...
