Method for the detection of Tc in seaweed samples coupling the use of Re as a chemical tracer and isotope dilution inductively coupled plasma mass spectrometry
(Elsevier Science BV, 2004)
The analysis of artificial radionuclide 99Tc in environmental samples requires of a chemical separation due to its low concentration, and therefore the use of a chemical yield tracer is peremptory. From the practical ...

Arctic Ocean sea ice drift origin derived from artificial radionuclides
(Elsevier Science BV, 2010)
Since the 1950s, nuclear weapon testing and releases from the nuclear industry have introduced anthropogenic radionuclides into the sea, and in many instances their ultimate fate are the bottom sediments. The Arctic Ocean ...

A 40-year retrospective European radon flux inventory including climatological variability
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
In this work, a 40-year retrospective European radon flux inventory has been calculated. Average values of the radon exhalation rate, probability distributions and seasonal fluctuations have been obtained. To achieve this, ...

Full-space potential gradient driven charge migration inside BiFeO₃ Photocathode
(American Chemical Society, 2022-09)
Solar–fuel conversion depends on effective collection of photocarriers in the photoelectrode. In practice, however, considerable photocarriers are lost in the bulk through recombination due to the absence of a driving ...

Mixed-anion mixed-cation perovskite (FAPbI₃)₀ꓸ₈₇₅ (MAPbBr₃)₀ꓸ₁₂₅: an ab initio molecular dynamics study
(American Chemical Society, 2022-05)
Mixed-anion mixed-cation perovskites with (FAPbI₃)₁-ₓ(MAPbBr₃)ₓ composition have allowed record efficiencies in photovoltaic solar cells, but their atomic-scale behaviour is not well understood yet, in part because their ...
