The spectrum of molecular nitrogen obtained from an electrodeless discharge in Ar N 2, Ne N 2, and He N 2 mixtures has been investigated at high resolution in the 900–1130 Å region. Transitions to the ground state, X 1 Σ g +, have been identified for the first time for the ...
IN a recent paper Mitra1has attempted to explain the remarkable features of the nitrogen afterglow, which have also been studied again by Lord Rayleigh2on the assumption of an emission that would follow the recombination between the ions N2+with electrons. It seems difficult to explain the previo...
In this study, single-crystal X-ray diffraction measurements on a laser-heated sample of molecular nitrogen were performed and the structure of ζ-N2was solved and refined at 63, 70 and 86 GPa. ζ-N2is found to have a monoclinic unit cell and an atomic arrangement close to that of ε...
Spectrum Analysis, MassBACKGROUND: Nitrogen removal using microbial fuel cells (MFCs) is of great interest owing to the potential benefits of bioenergy ... F Zhang,Z He - 《Journal of Chemical Technology & Biotechnology》 被引量: 125发表: 2012年 Further structure-activity relationship studies of...
(A) Schematic experiment: Raman spectra are recorded from a CB[n] solution in either H 2 O or D 2 O whilst it dries inside a nitrogen-flow cell. (B) Typical Raman spectrum highlighting the three vibrational regions of interest (shaded). The large peak between OD and OH stretch bands ...
2017, Journal of Molecular Structure Citation Excerpt : The consecutive connection of amine-carbonyl and methyl group made a chemical and physical attraction between atoms and created another hexagonal ring. When the amide group is conjugated between nitrogen lone-pair electrons and the carbonyl π-bon...
Another biostimulant produced by Sibbiopharm is Azofit. Nitrogen fixation plays an important role in the nitrogen cycle in nature, and is the most important source of nitrogen. Members of the genus, Azotobacter, play a key role in the soil nitrogen cycle, by fixing molecular nitrogen. Also, ...
Investigation of pore structure and fractal characteristics of organic-rich Yanchang Formation shale in central China by nitrogen adsorption/desorption analysis. J. Nat. Gas Sci. Eng. 22, 62-72. https://doi.org/10.1016/j.jngse.2014.11.020 [37] Loucks, R.G., Reed, R.M., Ruppel, S....
Here we provide the ‘Global Spectrum of Plant Form and Function Dataset’, containing species mean values for six vascular plant traits. Together, these traits –plant height, stem specific density, leaf area, leaf mass per area, leaf nitrogen content per dry mass, and diaspore (seed or spor...
The present work introduces a detailed molecular-level mechanism of the formation of MIL-53(Al), unraveled by combining in situ time-resolved high-resolution mass-spectrometry, magic angle spinning nuclear magnetic resonance spectroscopy and X-ray diffraction. In contrast to the general belief, the ...
