On the use of 210Pb-based records of sedimentation rates and activity concentrations for tracking past environmental changes
(Elsevier, 2022)
Lead-210 from natural atmospheric fallout is widely used in multidisciplinary studies to date recent sediments. Some of the 210Pb-based dating models can produce historical records of sediment accumulation rates (SAR) and ...

Atomic-Scale Model and Electronic Structure of Cu₂O/CH₃NH₃ PbI₃ Interfaces in Perovskite Solar Cells
(American Chemical Society, 2020-09)
Cuprous oxide has been conceived as a potential alternative to traditional organic hole-transport layers in hybrid halide perovskite-based solar cells. Device simulations predict record efficiencies using this semiconductor, ...

Determination of 210Po in low-level wild bilberries reference material for quality control assurance in environmental analysis using extraction chromatography and α-particle spectroscopy
(Walter de Gruyter GmbH, 2020)
Certified reference materials (CRM) are being widely used for quality control assurance in environmental analysis. For certain CRM, the analytes and/or the range of concentrations are not be available or certified at all. ...

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 ...
