Abstract:
... Black phosphorus (BP), as a typical layered two-dimensional (2D) material, has attracted tremendous attention due to its high carrier mobility, unique in-plane anisotropic structure and tunable direct bandgap. However, its instability due to environmental effects somehow limited its further progress in device applications. Actually, doping engineering has been proven to be an efficient and simple ...

Abstract:
... Black phosphorus is currently among the most explored two-dimensional (2D) materials. Currently, the synthesis methods are dominantly based on vapor-phase growth of black phosphorus. In this manuscript, we demonstrate large-scale synthesis of black phosphorus by rapid high-pressure transition of red phosphorus. The high-pressure conversion of red phosphorus led to high-density nanocrystalline blac ...

Abstract:
... The total phosphorus analyte (TP) has a long history of use in monitoring and regulatory applications relating to management of cultural eutrophication in freshwaters. It has become apparent, however, that the fraction of the TP analyte ultimately available to support algal growth varies significantly spatially (within a system), seasonally, and among systems. The algal bioassay methods described ...

Abstract:
... The chaotic distribution and dispersal of phosphorus (P) used in food systems (defined here as disorderly disruptions to the P cycle) is harming our environment beyond acceptable limits. An analysis of P stores and flows across Europe in 2005 showed that high fertiliser P inputs relative to productive outputs was driving low system P efficiency (38 % overall). Regional P imbalance (P surplus) and ...

Abstract:
... The increasing food waste volume causes inadequate resource usage and results in partially avoidable environmental degradation. Although previous research has developed cost-effective processes for food waste treatment, the significance of embedded resources in food waste, especially the unreplaceable and depleting phosphorus, has been overlooked. This paper quantifies food waste in China at the p ...

Abstract:
... Phosphorus (P) loss from intensive dairy farms is a pressure on water quality in agricultural catchments. At farm scale, P sources can enter in-field drains and open ditches, resulting in transfer along ditch networks and delivery into nearby streams. Open ditches could be a potential location for P mitigation if the right location was identified, depending on P sources entering the ditch and the ...

Abstract:
... Grasslands are a globally important use of land for food and fibre production, which often require the addition of phosphorus (P) fertiliser to maximise plant production. However, a large proportion of the added P can accumulate in pools of poorly available inorganic and organic P in the surface soil layer under grasslands. The aim of this study was to identify the chemical nature of the organic P ...
