Nitrogen-15 nuclear magnetic resonance spectra of isocyanates, isothiocyanates andN-sulfinylamines
The ^(15)N NMR spectra of ten isocyanates, four isothiocyanates, and four N-sulfinylamines have been obtained at the natural-abundance level by high-resolution NMR spectroscopy. The results show that isocyanates and isothiocyanates have ^(15)N chemical shifts over 200 ppm toward higher fields compared to those of N-sulfinylamines. The sensitivity of the ^(15)N shifts in these substances to substituent and electronic effects are discussed.
In this paper, a modeling and simulation method for planar interdigitated ruthenium oxide MEMS supercapacitor was proposed based on the electrochemical reaction mechanism of supercapacitor. The study simulated the planar interdigitated ruthenium oxide MEMS super capacitor using Comsol software. The highly accurate charge and discharge curves of the super capacitor, electric potential distribution graph and the concentration distribution graph were got through simulation. The effects of two structure-parameters were discussed in the research.
