Human alteration of the global nitrogen and phosphorus soil balances for the period 1970-2050 [PDF]

open access: yes, 2009
The Millennium Ecosystem Assessment scenarios for 2000 to 2050 describe contrasting future developments in agricultural land use under changing climate. Differences are related to the total crop and livestock production and the efficiency of nutrient use

Computation‐Guided Dual‐Site Electrocatalysts for Record‐Performance Nitrite‐to‐Ammonia Conversion

open access: yesAdvanced Science, EarlyView.
Designing Cu doped ZnO catalysts for NO2RR via first principles calculation and boosting electrocatalytic nitrite reduction through Cu‐ZnO synergistic deoxygenation, hydrogenation, and NH3 desorption. Cu doping elevates the d‐band center of Zn, strengthening *NO2 binding and deoxygenation, while ZnO sites regulate water adsorption and dissociation ...

Use of inorganic fertiliser in place of poultry manure for rehabilitation of gold and bauxite ore refining residues [PDF]

open access: yes, 2000
Ore refining residues are difficult substrates for revegetation because they often contain extremely low plant available levels of one or more essential elements (Hossner and Hons 1992).

Molecular Weaving of Mixed‐Addenda Polyoxometalates into MOF Nanochannels as Electron‐Buffering Reservoirs for Enhanced Nitrate‐to‐Ammonia Electrocatalysis

open access: yesAdvanced Science, EarlyView.
Synergistic interaction between P2W17V1 and FeMOF owing to its efficient proton/electron transfer affording high yield and Faradaic efficiency in electrocatalytic nitrate reduction to ammonia. ABSTRACT Electrochemical conversion of nitrate pollutants into value‐added ammonia (e‐NO3RA) offers a sustainable pathway for nitrogen valorization, yet hinges ...

Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

open access: yesAdvanced Science, EarlyView.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.

Versatile DNA Hydrogel‐Mediated Delivery of Ginsenoside‐Encapsulated Small Extracellular Vesicles to Boost Diabetic Wound Repair

open access: yesAdvanced Science, EarlyView.
This study presents a DNA hydrogel‐mediated delivery system, in which ginsenoside (GS) molecules are incorporated into small extracellular vesicles (sEV) secreted by mesenchymal stem cells (MSCs) and the formed complexes are then anchored in DNA hydrogels via aptamer‐CD63 affinity as “GS/sEV@DNAgels”, to improve diabetic wound repair.

Enhanced fertility after diagnostic hysterosalpingography using water-soluble contrast media

open access: yesZanco Journal of Medical Sciences, 2015
Background and objectives: A possible therapeutic effect of diagnostic tubal patency testing has been debated in the literature for more than half a century. The aim of this study was to evaluate the effect of flushing the fallopian tubes with water-soluble contrast medium during hysterosalpingography on subsequent pregnancy rates and to find out ...

The mineralization of commercial organic fertilizers at 8°C temperature [PDF]

open access: yes, 2008
In organic production only organic fertilizers and soil conditioners can be used to supply the soil with nitrogen. The mineralization of these products is slow and so there can be problems with the supply of nitrogen, when the demand of the plants is ...
