Formation mechanism of nanotubes comprising layers of PbS nanoparticles in polymer-surfactant solutions
(2006)The crystallization of PbS in aqueous solutions containing the surfactant sodium dodecyl sulfate (SDS) and hydrophilic polymers resulted in a novel type of metastable nanotubes, the walls of which consist of layers of ...

Long-Lived Hot Carriers in Formamidinium Lead Iodide Nanocrystals
(2017)The efficient harvesting of hot carrier energy in semiconductors is typically inhibited by their ultrafast thermalization process. Recently, highly promising experiments reported on the slowdown of the intraband relaxation ...

Redox chemistry of sulphate and uranium in a phosphogypsum tailings dump
(2010)The present study aims to assess the effect of redox conditions existing within the tailings dump on the stability of phosphogypsum (e.g. sulphate reduction) and uranium(VI). Phosphogypsum sampling and in-situ measurements ...

Relations of crystal structure to magnetic properties in the quasi-one-dimensional compound PbNi1.88Mg0.12V 2O8
(2004)The crystal structure of the quasi-one-dimensional oxide PbNi 1.88Mg0.12V2O8 has been studied by Rietveld analysis of combined high-resolution neutron and X-ray powder diffraction data at 300K and at low temperatures. The ...

Spin-gap and antiferromagnetic correlations in low-dimensional PbNi2-xAxV2O8 compounds (A = Mg, Co)
(2002)The effect of the impurity doping in the quantum-spin chains of the PbNi2V2O8 Haldane-gap compound is studied. We report elastic neutron scattering and bulk magnetic susceptibility measurements on the quasi-one-dimensional ...
