TL;DR: A noble metal-free CoO/BiVO4 p-n heterojunctions with micro-nano spherical structure were synthesized via a simple solvothermal method as discussed by the authors.

TL;DR: Geochemical baseline can be used not only to determine the enrichment degree but also as a potentially useful tool for identifying the pollution source (local and non-point source) of heavy metals in sediments.

TL;DR: The spatial and temporal distribution characteristics of DOM concentration in Lake Hulun were thoroughly surveyed, and the optical characteristics, fluorescence components and sources of DOM were analyzed by excitation emission matrix (EMM) and parallel factor analysis (PARAFAC) technology as discussed by the authors.

TL;DR: In this article, the spatial distribution and composition characteristics, sources, and contribution to eutrophication of dissolved organic matter (DOM) in the overlying water of Lake Taihu, a typical eutrophic lake in China, were analyzed by ultraviolet-visible spectra and three-dimensional fluorescence excitation-emission matrix spectra combined with the statistical decomposition technique, parallel factor analysis.

TL;DR: In this article, diffusive gradients in thin film (DGT), high-resolution dialysis technique (HR-Peeper) and traditional methods were jointly used to study the occurrence characteristics, pollution degree, bioavailability, and mobility of sediment metals in the northern lake wetlands of Jiaxing City in Taihu Lake Basin.
