A. L. C. Pereira、P. A. Schulz2008-02-19Physical Review B
The effects of disorder and valley polarization in graphene are investigated in the quantum Hall regime. We find anomalous localization properties for the lowest Landau level (LL), where disorder can induce wave function delocalization (instead of localization), both for white-noise and Gaussian-correlated disorders.…

Electron-density maps are calculated by Fourier syntheses with coefficients based on structure factors. Diffraction experiments provide intensities up to a limited resolution; as a consequence, the Fourier syntheses always show series-termination errors. The worse the resolution, the less accurate is the Fourier repre…

The effect of neutron flux on the formation of irradiation-induced clusters in reactor pressure vessel (RPV) steels is an unresolved issue. Small-angle neutron scattering was measured for a neutron-irradiated RPV weld material containing 0.22 wt% impurity Cu. The experiment was focused on the influence of neutron flux…

Aizu's characterization of the 773 species of phase transitions by magnetization, polarization and strain is extended to include characterization by the recently observed toroidal moment. The resulting distinction quadruplet characterization is then used to classify the species into sub-ensembles, extending Schmid's c…

The aim of the present paper is to investigate the behaviour of the kinematic viscosity, mean-square displacement and free volume of glycerol in order to theoretically and experimentally evaluate the fragility degree. Starting from the dependence of viscosity on temperature, the behaviour of the mean-square displaceme…

Conventional alginate/poly-L-ornithine (AP) membranes used to immunoisolate foreign tissue transplants fail in long-term transplantations of immortal cell lines. We have developed a novel layer-by-layer (LbL) membrane using polystyrene sulfonate and polyallylamine hydrochloride (PSS/PAH) on top of the coherent AP memb…

Oxygen vacancy disorder is very common in RBaCo 2 O 5+δ cobaltites with large rare earths (R). This disorder affects the magnetic interactions and, obviously, the magnetic properties of these compounds. In this work we report the preparation and characterization of a well ordered PrBaCo 2 O 5.50 sample that has allowe…

Docetaxel (DX) is one of the most effective antineoplastic drugs. Its current clinical administration is limited because of its hydrophobicity and serious side effects. A polymer/DX conjugate is designed and successfully prepared to solve these problems. It is monomethoxy-poly(ethylene glycol)-block-poly(L-lactide)/DX…

A systematic procedure for producing ZnO nanoparticles by heating ethanol and salt under pressure has been used to make pure ZnO and ZnO doped with cations of all 3d metals from Sc to Cu. When the ZnO is uniformly doped with the 3d cations, the nanoparticles show no ferromagnetism down to 4.2K. However, when the precu…

Two samples of the type I clathrate Ba 8 Zn 8 Ge 38 have been prepared by a self-flux method with different cooling rates. Transport properties have been measured for a large single crystal of Ba 8 Zn 8 Ge 38 from the slow cooled batch, and they reveal the sample to be semiconducting. A high Seebeck coefficient of −17…
