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.

Adsorption behavior and mechanism of Mg/Fe layered double hydroxide with Fe3O4-carbon spheres on the removal of Pb(II) and Cu(II).

Journal of Colloid and Interface Science, 2019
Mg/Fe layered double hydroxide loaded with Magnetic(Fe3O4) carbon spheres (MCs@Mg/Fe-LDHs) was firstly synthesized by a facile in-situ co-precipitation method to remove Pb(II) and Cu(II) pollution.

Performance of Pb(II) removal by an activated carbon supported nanoscale zero-valent iron composite at ultralow iron content.

Journal of Hazardous Materials, 2019
Activated carbon supported nanoscale zero-valent iron composite (NZVI/AC) at ultralow iron content was synthesized and used to remove Pb(II) from aqueous solution. The technical characterization revealed that the loaded amorphous NZVI nanoparticles had a

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.

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.

A novel lead(II) framework containing Pb–O–Pb and Pb–Cl–Pb helical chains

Inorganic Chemistry Communications, 2008
Abstract Under hydrothermal conditions, using 5-methyl-pyrazine-2-carboxylic acid (HL) and lead(II) chloride, a new 2D lead(II) framework [Pb(L)(μ2-Cl)(H2O)]n can be isolated, in which infinite Pb–O–Pb helical chains can be observed. Interestingly 1 stacks in ABAB… ways, in one layer right-handed Pb–O–Pb and left-handed Pb–Cl–Pb helical chains are ...

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.
