Nitrates have long been considered as harmful dietary components and judged responsible for deleterious effects on human health, leading to stringent regulations concerning their levels in food and water. However, recent studies demonstrate that dietary nitrate may have a major role in human health as a non-immune mechanism for host defence, through its metabolism to NO in the stomach. NO is a ...

We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...

In this study bulk airborne aerosol composition measured by the PILS-IC (integration time of 3 min 24 s) during TRACE-P P3B Flight 10 are used to investigate the ionic chemical composition and mixing state of biomass burning particles. A biomass burning plume, roughly 3– 4 days old, moderately influenced by urban pollution aerosols recorded in the Philippine Sea is investigated. Focusing on the...

NOx emissions in the atmosphere can cause various environmental problems, which should be strictly controlled and regulated. Furthermore, because of limited amount crude oil resources world severe global warming, development fuel-efficient vehicles has long been desired. Accordingly, efficient storage reduction catalysts have developed over decades, called NSR (NOx storage/reduction) catalysts....

We report the synthesis of original imidazolium salts with tetraphenylborate anion and their use as precursors for boron, nitrogen co-doped carbon materials. In addition to benefic effet tetraphenylborate...

Rates of nitrogen application were studied in relation to commercial yield and fruit quality of cucumber plants (Cucumis sativus L. cv. Bunex). All plants were grown under controlled conditions in a greenhouse. Treatments consisted of the application of N as KNO3 (N1, 2.5 g m-2; N2, 5 g m-2; N3, 10 g m-2; N4, 20 g m-2; and N5, 40 g m-2). The fruits of cucumber from the N3 and N4 treatments were...

Although the electronic properties of graphene layers can be modulated by various doping techniques, most of doping methods cost degradation of structural uniqueness or electrical mobility. It is matter of huge concern to develop a technique to improve the electrical properties of graphene while sustaining its superior properties. Here, we report the modification of electrical properties of sin...

Davis, J. B. (Socony Mobil Oil Co., Inc., Dallas, Tex.), V. F. Coty, and J. P. Stanley. Atmospheric nitrogen fixation by methane-oxidizing bacteria. J. Bacteriol. 88:468-472. 1964.-Methane-oxidizing bacteria capable of fixing atmospheric nitrogen were isolated from garden soil, pond mud, oil field soil, and soil exposed to natural gas, indicating a rather wide prevalence in nature. This may exp...

RATIONALE Because of the threat of bombings using improvised explosives containing ammonium nitrate (AN), law enforcement and intelligence communities have been interested in stable isotope techniques for tracking and discriminating AN sources. Separate analysis of the AN component ions ammonium and nitrate would add discriminatory power to these techniques. METHODS Ammonium ions in dissolved...

In studies on the synthesis of urea in vitro, the nitrogen is usually supplied as NH&l or as (NHJ)$SO~ (l-3). It has been suggested that the mechanism by which such nitrogen enters the cycle and forms urea is somewhat different from that utilized by nitrogen supplied in the form of glutamine or amino acids. Leuthardt and Glasson (2) believe that ammonia from inorganic salts enters the cycle dir...
