The Pb–Pb and O–Pb Nuclear Spin Coupling in Ba(Pb,Bi)O3 Oxides

Journal of Superconductivity and Novel Magnetism, 2006
We report the 17O, 207Pb NMR and 17O–207Pb SEDOR study of superconducting BaPb1-x Bi x O3 (x 0.35) oxides. Inhomogeneous The results points to the formation of microscopically inhomogeneous distribution of the carrier density in metallic phase.

Critical thermodynamic evaluation and optimization of the Pb–Pr, Pb–Nd, Pb–Tb and Pb–Dy systems

Calphad, 2014
Abstract All available experimental data on phase equilibria and thermodynamic properties of the Pb–Pr, Pb–Nd, Pb–Tb and Pb–Dy binary systems were reviewed and critically examined. A thermodynamic optimization of these systems is presented for the first time.

The structure of molten K-Pb, Rb-Pb and Cs-Pb alloys

Journal of Physics: Condensed Matter, 1991
The authors have considered previously published neutron diffraction data, obtained at two different sources, on the molten alloys KxPb1-x, RbPb and CsPb. The difference between results for the same system obtained at the two sources has been shown to be attributable to instrumental resolution.

Electrochemical behaviour of the cell Pb/PEO40. Pb(ClO4)2/Pb

Electrochimica Acta, 1989
The electrochemical behaviour of the polymer-based cell Pb/(PEO)40. Pb(ClO4)2/Pb has been investigated over the temperature range 20–160°C by means of impedance spectroscopy and dc polarization methods. The bulk resistance and the charge transfer resistance display a linear trend in an Arrhenius plot.

Photoresponse and barrier height of Pb-Pb oxide-Pb sandwich structures

Applied Physics Letters, 1975
The spectral dependence of the photocurrent in Pb-Pb oxide-Pb structures is investigated varying both the electrode thickness and the resistance of the junctions. The samples exhibit sign reversal of the photocurrent with changing photon energy hν. The effect is strongly controlled by the electrode thickness and direction of illumination.

U–Pb, Pb–Pb and Re–Os sulphide geochronology

2016
The U–Pb decay scheme is the most widely applied geologically robust geochronometer. Due to its unique attribute of containing two independent decay chains, starting from different parent isotopes and finishing with different daughter isotopes of the same elements, it is possible to cross-correlate the data obtained simultaneously to produce routine ...

Synthesis of Pb-zoisite and Pb-lawsonite

Neues Jahrbuch für Mineralogie - Abhandlungen, 2011
Hydrothermal syntheses of Pb-zoisite Pb2Al3(SiO4|Si2O7|O|OH) and Pb-lawsonite PbAl2(Si2O7|(OH)2)•H2O were per- formed at high pressure and temperature conditions with standard piston cylinder press experiments. Starting materials were mix- tures of PbAl2O4, SiO2, PbO and H2O.

KS0andΛProduction in Pb-Pb Collisions atsNN<…

2013
The ALICE measurement of K(S)(0) and Λ production at midrapidity in Pb-Pb collisions at √(s(NN))=2.76 TeV is presented. The transverse momentum (p(T)) spectra are shown for several collision centrality intervals and in the p(T) range from 0.4 GeV/c (0.6 GeV/c for Λ) to 12 GeV/c.

Heavy-flavour correlations in pp, p–Pb and Pb–Pb collisions

Nuclear Physics A, 2014
Abstract Heavy quarks (charm and beauty) are produced in initial hard scattering processes in heavy-ion collisions, before the formation of a strongly interacting medium, the Quark Gluon Plasma. Insight into the effects of the medium on charm and beauty production can be obtained by measuring the angular correlations between open heavy-flavour ...
