Macromolecular Structural Unit Construction of Fushun Nitric-Acid-Oxidized Coal
, 2015Biological liquefaction of nitric-acid-oxidized low-rank coal is well-documented in the literature. However, few studies focused on the macromolecular structure of nitric-acid-oxidized low-rank coal.

Nitric oxide and macrophage function.
Annual Review of Immunology, 1997At the interface between the innate and adaptive immune systems lies the high-output isoform of nitric oxide synthase (NOS2 or iNOS). This remarkable molecular machine requires at least 17 binding reactions to assemble a functional dimer.

AbstractElectron spectroscopy for chemical analysis (ESCA) has been employed to follow the surface nitration of cellulose papers in nitric acid–water and nitric acid–dichloromethane mixes with the aim of: elucidating the identity of the nitrating species in these mixes and from comparison of surface and bulk degree of substitution (DOS) further ...

Mechanism of Nitric Acid Reduction and Kinetic Modelling
, 2014In France, the recycling of nuclear waste fuels involves the use of hot concentrated nitric acid. The understanding and prediction of the behaviour of the structural materials (mainly austenitic stainless steels) requires the determination and ...

Single particle analysis of individual sea spray aerosol particles shows that cations (Na(+), K(+), Mg(2+), and Ca(2+)) within individual particles undergo a spatial redistribution after heterogeneous reaction with nitric acid, along with the development

This chapter focuses on the evaluation of nitric acid production. Apart from presenting the different methods used over time, and the technical and historical reasons for using the various technologies, the complete analysis of current processes is presented based on mass and energy balances.

The measurement of As species in rice is normally accomplished by extraction followed by HPLC-ICPMS analysis. This method, however, has not been comprehensively validated by comparing these speciation results with XANES, which does not require sample ...

Speciation of platinum(IV) in nitric acid solutions.
Inorganic Chemistry, 2013The speciation of platinum(IV) ions in nitric acid (6-15.8 M) solutions of H2[Pt(OH)6] has been studied by (195)Pt NMR and Raman spectroscopy. Series of aqua-hydroxo-nitrato complexes [Pt(L)(x)(NO3)(6-x)] (L = H2O or OH(-); x = 0, ..., 6) were found to ...
