Nitrate attenuation in a restored river floodplain system: River Cole (Oxfordshire - UK) [PDF]

open access: yes, 2010
PhDRestoring river-floodplain connectivity has been proposed as an alternative management measure for natural flood defence through the temporary storage of floodwaters and the attenuation of flood peaks downstream.

Role of oxide support in electrocatalytic nitrate reduction on Cu [PDF]

open access: yes, 2022
The electrochemical nitrate reduction reaction (NO3RR) has the potential for distributed water treatment and renewable chemical synthesis. Cu is an active monometallic electrocatalyst for the NO3RR in acidic and alkaline electrolytes, where activity is ...

Differential nitrate accumulation, nitrate reduction, nitrate reductase activity, protein production and carbohydrate biosynthesis in response to potassium and sodium nitrate [PDF]

open access: yes, 2011
For most of the cultivated crops, nitrate is the major source of nitrogen. Most steps in the nitrate assimilatory pathway are nitrate inducible. In this study, Cucurbita pepo were grown in washed sand per pot at three potassium and sodium nitrate ...

NITRATE REDUCTION AND ASSIMILATION IN CHLORELLA [PDF]

open access: yesJournal of General Physiology, 1948
1. Nitrate reduction and assimilation have been studied in Chlorella pyrenoidosa under growth conditions by observing effects on the CO2/O2 gas exchange quotient. 2. During assimilation of glucose in the dark, nitrate reduction is noted as an increase in the R.Q. to about 1.6 caused by an increased rate of carbon dioxide production.

Iso-osmotic regulation of nitrate accumulation in lettuce (Lactuca sativa L.) [PDF]

open access: yes, 2010
Concerns about possible health hazards arising from human consumption of lettuce and other edible vegetable crops with high concentrations of nitrate have generated demands for a greater understanding of processes involved in its uptake and accumulation ...

Electrochemical nitrate reduction in acid enables high-efficiency ammonia synthesis and high-voltage pollutes-based fuel cells

open access: yesNature Communications, 2023
Most current research is devoted to electrochemical nitrate reduction reaction for ammonia synthesis under alkaline/neutral media while the investigation of nitrate reduction under acidic conditions is rarely reported.

Role of electronic structure on nitrate reduction to ammonium: a periodic journey [PDF]

open access: yes, 2022
Electrocatalytic reduction of waste nitrate to ammonium provides a circular process with reduced carbon dioxide emissions compared to current nitrate treatment and ammonia production processes. However, electrocatalysts require a delicate balance between

Isotopic fractionation associated to nitrate attenuation by ferrous iron containing minerals [PDF]

open access: yesE3S Web of Conferences, 2019
Biotic and abiotic laboratory experiments of nitrate and nitrite reduction by Fe-containing minerals were performed and the isotopic fractionation of the different reactions was calculated in order to determine whether it is possible to distinguish ...

An 15N study of the effects of nitrate, ammonium, and nitrate + ammonium nutrition on nitrogen assimilation in Zea Mays L. [PDF]

open access: yes, 1984
Bibliography: leaves 113-134.A brief review of the literature on the effects of nitrate and ammonium nitrogen sources on plant growth, and the assimilation of those nitrogen sources, has been presented.

Quantification of nitrate removal by a flooded alluvial zone in the Ill floodplain (Eastern France) [PDF]

open access: yes, 1999
The nitrate reducing capacity of a flooded system in the Ill floodplain (Eastern France) was investigated for a period of 2 years. The methodology used consisted of a spatio-temporal monitoring of stream flow and nitrate concentrations in the groundwater
