A simple and straightforward method using microwave-assisted reactions is presented for the functionalization of graphene oxide with aromatic non-aromatic amines.
The shielding tensor in 13C nuclear magnetic resonance (NMR) offers important information about the structural aspects of carbon materials from a local point view. Not only symmetry site but also presence distortions can affect values isotropic constant, anisotropy, and deviation axial symmetry. In this report, single graphene sheet was calculated using density functional theory (DFT) via gauge-including projector augmented plane wave (GIPAW) method. After performing convergence tests...
Coumarins have great pharmacotherapeutic potential, presenting several biological and pharmaceutical applications, like antibiotic, fungicidal, anti-inflammatory, anticancer, anti-HIV, healing activities, among others. These molecules are practically insoluble in water, for it became necessary to complex them with cyclodextrins (CDs), which influence their bioavailability the target organism. In this work, we studied two coumarins, was possible conclude that there were structural differences...
DFT calculations and solid-state NMR spectroscopy are a powerful combination to provide detailed characterization of phosphorus-containing graphene oxides with outstanding properties for diverse applications.
Solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy was used in this work to analyze the physical and chemical properties of plasma blacks carbon deposits produced by thermal cracking natural gas using different types reactors. In a typical configuration with double-chamber reactor, N 2 or Ar injected as working first chamber second chamber, inside arc column. The solid residue collected at points throughout apparatus analyzed solid-state NMR spectroscopy, either cross...
