Nitrogen solid

It will be interesting to discern if the preceding transformations are a consequence of electronic effects due solely to nitrogen incorporation, or if there is some influence of the growth process itself. Different theoretical approaches were used in the study of hydrogen-free carbon-nitrogen solids.

Ammonia in Multinutrient Fertilizers. All the ammonia-based fertilizers discussed thus far contain only one of the three major plant nutrients, namely nitrogen. Referring again to Fig. 24.8, one may see that ammonia is the source of fertilizer nitrogen also, either directly or via nitrogen solids or solutions, in multinutrient fertilizers. These are fertilizers that contain two or three of the major plant nutrients—nitrogen, phosphorus, and potassium. Ammonium phosphates, both mono- and di-,... 

It is noteworthy that this family of complexes had been known for decades, bnt what made the newly introduced derivatives excellent catalysts for polymerizing ethylene was the incorporation of very bulky aryl substituents (e.g. 2, 6-(i-Pr)2C6H3) on the diimine nitrogens. Solid-state structural and computational studies have indicated that the aryl...

A number of VMC and DMC calculations of atomic, molecular, and solid systems have been carried out by this approach. This includes sp and transition element atoms [32, 46, 52] silicon and carbon clusters [55, 58], nitrogen solids [59], and diamond [60]. Our experience indicates that with a sufficient number of valence electrons one can achieve a high final aecuracy. This, however, requires using 3s and 3p in the valence space for the 3d elements and, possibly, 2s and 2p states for elements such as Na. Once the core is sufficiently small, the systematic error of the fixed-node...

Solvent extraction can also be achieved under milder conditions but the product may be a high-nitrogen solid or a heavy oil with only low yields of light oils and gases. The more severe conditions are more effective for sulfur and nitrogen removal to produce a lighter liquid product that is more amenable to downstream processing. 

Carotenoids are commonly extracted from liquid samples (plasma/serum) into lipophilic solvents such as hexane, hexane-ethyl acetate, or diethyl ether, mostly after deproteinization with ethanol or methanol, which also helps to liberate the lipidic substances from protein binding. Extracts should be protected from light and acids and antioxidants may usefully be added. The extract is either used as such or is concentrated under oxygen-free nitrogen. Solid samples, e.g., foods, are either extracted with a solvent miscible with water (acetone, methanol) or, after dehydration of the sample, with a water immiscible solvent. Cleanup of the extract and fractionation of the pigments may involve saponification and/or open-column chromatography.

The case structure of nitiided steel depends on its type, concentration of alloying elements and particular conditions of nitiiding treatment. The diffusion zone is the original core microstructure with the addition of nitride precipitates and nitrogen solid solution. The surface compoxmd zone is the region where y (Fe4N) and e (Fe2-3N) intermetallics are formed. The corrosion resistance of steel varies with nitrided layer structure. The surface "white layer" can contain e nitride, y nitride or a two phase mixture e+y, below that is the diffusion zone. In add solutions the iron nitrides corrode more slowly than iron and when the "white zone" is formed on the steel surface the improvement of the corrosion resistance is a fact. In Fig. 1 is shown the typacal structure of nitrided plain carbon steel (Minkevich, 1965).
