Monitoring of nitrites and nitrates levels in leafy vegetables (spinach and lettuce): a contribution to risk assessment

Journal of the Science of Food and Agriculture, 2014
BACKGROUND Nitrites and nitrates are compounds considered harmful to humans and the major part of the daily intake of nitrates in foodstuffs is related to vegetable consumption.

Computational Screening of High Activity and Selectivity TM/g-C3N4 Single-Atom Catalysts for Electrocatalytic Reduction of Nitrates to Ammonia.

Journal of Physical Chemistry Letters, 2021
Electrocatalytic reduction of nitrates (NO3RR) selectively generating ammonia (NH3) opens up a new idea for treating nitrates in wastewater, which not only reduces nitrates but also obtains the valuable product ammonia.

Comprehensive Study about the Photolysis of Nitrates on Mineral Oxides.

Environmental Science and Technology, 2021
Nitrates formed on mineral dust through heterogeneous reactions in high NOx areas can undergo photolysis to regenerate NOx and potentially interfere in the photochemistry in the downwind low NOx areas.

Nitrate signalling: Functions of a nitrate transceptor [PDF]

Nature Plants, 2015
The nitrate transporter NRT1.1 is a versatile plasma-membrane protein that mediates not only nitrate uptake in roots, but also nitrate sensing and signalling. A study of the structural features of NRT1.1 reveals how this protein can coordinate a range of physiological and morphological responses to nitrate.

Alkali Nitrates Molten Salt Modified Commercial MgO for Intermediate-Temperature CO2 Capture: Optimization of the Li/Na/K Ratio

, 2017
The promoting effect of alkali nitrates molten salt on the CO2 capture capacity of a commercial MgO was investigated in detail. In particular, the ratio of Li/Na/K nitrates and the loading of the molten salt mixture on the MgO particles were optimized ...

Direct Nitration of Vinylcycles with Copper Nitrate

Organic Letters, 2023
A direct nitration of vinylcyclopropanes is disclosed with Cu(NO3)2 and KI in a regio- and stereoselective manner to afford nitroalkenes efficiently, where the cyclopropane skeleton was retained. The given method could be extended to other vinylcycles as well as biomolecule derivatives with wide substrate scope, good functionality tolerance, and ...

Nitrates

Medical Clinics of North America, 1988
Nitroglycerin and the long-acting nitrates are playing an increasingly important role in cardiovascular medicine. These agents are recommended in all of the various anginal syndromes and are as effective as the beta-blockers and calcium channel antagonists.
