Geoquímica de fósforo como indicadora da qualidade ambiental e dos processos estuarinos do Rio Jaguaribe - costa nordeste oriental brasileira Phosphorus geochemistry as a proxy of environmental estuarine processes at the Jaguaribe River, Northeastern Brazil

open access: yesQuímica Nova, 2007
Phosphorus geochemistry as a proxy of environmental estuarine processes at the Jaguaribe River, Northeastern Brazil. Sedimentation of different phosphorus geochemical fractions can characterize the natural or anthropogenic processes dominant in the ...

The influence of atmospheric organic carbon and organic nitrogen on biogeochemistry of the (sub-) tropical North Atlantic Ocean

open access: yes, 2011
The (sub-) tropical North Atlantic Ocean is a region which is influenced by oceanic upwelling along the West African coast, an extensive oxygen minimum zone and also by atmospheric dust deposition from the Sahara and Sahel regions and the industrial ...

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

The importance of dissolved organic nutrients in the biogeochemistry of oligotrophic gyres

open access: yes, 2005
The aim of this thesis is to contribute to the observational database in order to address fundamental questions as to how dissolved organic nutrients influence N and P budgets, how they affect nutrient cycling and the sustainment of biological production

Soil and Landscape Factors Affecting Phosphorus Loss from the Fitzgerald River Catchment in South West of Western Australia [PDF]

open access: yes, 2009
Following over 100 years of agriculture and continuous phosphorus (P) fertilizer application in the south west of Western Australia, there is a growing risk of P transport from cropping and pasture land to streams.

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

open access: yesAdvanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Unraveling iron oxides as abiotic catalysts of organic phosphorus recycling in soil and sediment matrices

open access: yesNature Communications
In biogeochemical phosphorus cycling, iron oxide minerals are acknowledged as strong adsorbents of inorganic and organic phosphorus. Dephosphorylation of organic phosphorus is attributed only to biological processes, but iron oxides could also catalyze ...

Dissolved phosphorus retention in buffer strips: Influence of slope and soil type [PDF]

open access: yes, 2015
Phosphorus (P) contributes to eutrophication of surface waters and buffer strips may be implemented to reduce its transfer from agricultural sources to watercourses.

Sulfur‑Containing Additives for Enhanced Kinetics and Interfacial Stability of Phosphorus Anodes in Li‑Ion Batteries

open access: yesAdvanced Science, EarlyView.
A novel synergistic strategy by employing dual functional sulfur‐containing additives of lithium sulfide (Li2S) and its oxidation product lithium sulfate (Li2SO4) was proposed. Li2SO4 absorbs the solvent molecules to direct the formation of a uniform, Li2O‐rich, and adaptive interphase, which accommodates volume expansion and suppresses parasitic ...

Dissolved organic nitrogen in the river test and estuary

open access: yes, 2005
Studies of nutrients in rivers and estuaries have generally focused on dissolved inorganic nitrogen (DIN), although this accounts for only a part of the total nitrogen (TN) in these systems.
