Nitrate deposition to surface snow at Summit, Greenland, following the 9 November 2000 solar proton event [PDF]
, 2014 This study considers whether spikes in nitrate in snow sampled at Summit, Greenland, from August 2000 to August 2002 are related to solar proton events. After identifying tropospheric sources of nitrate on the basis of correlations with sulfate, ammonium,

Efficient syntheses of climate relevant isoprene nitrates and (1R,5S)-(−)-myrtenol nitrate [PDF]
, 2016 Here we report the chemoselective synthesis of several important, climate relevant isoprene nitrates using silver nitrate to mediate a ’halide for nitrate’ substitution. Employing readily available starting materials, reagents and Horner–Wadsworth–Emmons

Aquatic Nitrate Retention at River Network Scales Across Flow Conditions Determined Using Nested In Situ Sensors [PDF]
, 2017 Nonpoint pollution sources are strongly influenced by hydrology and are therefore sensitive to climate variability. Some pollutants entering aquatic ecosystems, e.g., nitrate, can be mitigated by in‐stream processes during transport through river ...

Aminoethyl nitrate – the novel super nitrate? [PDF]
British Journal of Pharmacology, 2009 Long‐term use of most organic nitrates is limited by development of tolerance, induction of oxidative stress and endothelial dysfunction. In this issue of the BJP, Schuhmacher et al. characterized a novel class of organic nitrates with amino moieties (aminoalkyl nitrates).

Chemical patterns of the TINRO Basin (Okhotsk Sea) in abnormally cold years
Известия ТИНРО, 2018 Chemical parameters (dissolved oxygen content, concentrations of silicon, phosphate and nitrate, nitrate deficiency) in the TINRO Basin of the Okhotsk Sea (~1000 m depth) are considered for the years 2001–2002 with abnormally cold winters.

Biotropia: The Southeast Asian Journal of Tropical Biology, 2023 Java ginseng (Talinum paniculatum Gaertn.) is a medicinal plant, the roots of which are commonly used in traditional medicine. In its natural habitat, the roots grow very slowly, requiring two to three years to produce 100 g of roots per plant.

Mobilisation or dilution? Nitrate response of karst springs to high rainfall events [PDF]
, 2014 peer-reviewedNitrate (NO3−) contamination of groundwater associated with agronomic activity is of major concern in many countries. Where agriculture, thin free draining soils and karst aquifers coincide, groundwater is highly vulnerable to nitrate ...
