The application of NMR imaging as a nondestructive technique to detect physical flaws in green state fiber reinforced ceramic matrix composites is also discussed in this chapter.doi:10.1016/S0066-4103(08)60090-3H. KawazoeAnnual Reports on Nmr Spectroscopy...
NMR Spectroscopypetroleum derivatesComplex chemical composition and physical properties of oil and fuel make their complete characterization very difficult. Components present in oil and oil products differ in structure, size, polarity and functionality. The presence and structure of specific hydrocarbons in...
NMR Spectroscopy differs favorably from other physical methods of investigation (IR and UV spectroscopy) in that in some cases it makes it possible to detect directly the formation of intermediate products of chemical reactions (ions, reaction complexes, solvates, etc.). However, it should be ...
NMR spectroscopy of oriented molecules is employed to study weak molecular interactions. The information is obtained from the changes in the molecular order and the structure as a result of the complexation. Specific results on the pi an... K. V. Ramanathan,Nitin P. Lobo,CL Khetrapal 被引量...

Molecular characterization of compost at increasing stages of maturity. 2. Thermochemolysis-GC-MS and 13C-CPMAS-NMR spectroscopy. Off-line pyrolysis TMAH-GC-MS (thermochemolysis) and solid-state 13C NMR spectroscopy were applied for the direct molecular characterization of composted o... R Spac...
Grafting of organosilane-functionalized substances onto the surface of nano-sized silica particles was studied by temperature-programmed oxidation (TPO), solid-state 13C and 29Si MAS NMR and DRIFT spectroscopy. By using 29Si MAS NMR quantitative data on the proportions of the various grafted structu...
