Adsorption of CO2 on the surface of Single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (SWCNTs) were studied through using density functional theory (DFT) calculations. Optimizations of geometric were performed at the B3PW91 level of 6-311++G** method standard basis set using GAUSSIAN 03 package of program [1]. Structural models were optimized and adsorption energies, band gap, charge...

High-resolution magic angle spinning (HR-MAS) one- and two-dimensional 1H and 13C nuclear magnetic resonance (NMR) spectroscopy has been used to study intact glioblastoma (GBM) brain tumour tissue. The results were compared with in vitro chemical extract and in vivo spectra. The resolution of 1H one-dimensional, 1H TOCSY and 13C HSQC HR-MAS spectra is comparable to that obtained on perchloric e...

Numerous low-Mr metabolites--including creatinine, citrate, hippurate, glucose, ketone bodies, and various amino acids--have been identified in 400- and 500-MHz proton nuclear magnetic resonance (1H NMR) spectra of intact human urine. The presence of many of these was related to the specific condition of the donors: humans in different physiological states (resting, fasting, or post-exercise) a...

Introduction: Cannabidiol (CBD) has become a promising bioactive for the next decades after recent recognition of medical potential Cannabis derivatives by United Nations member countries, as it no psychotropic your isomer ∆9-tetrahydrocannabinol (∆9-THC). The differentiation these isomers been studied decades. Recent studies demonstrate that even with more subtle chemical characteristics, such...

As potential new analgesics, the corresponding 4-hydroxy-2,2-dioxo-1H-2λ⁶,1-benzothiazine-3-carboxanilides have been obtained by amidation of ethyl 4-hydroxy-2,2-dioxo-1H-2λ⁶,1-benzothiazine-3-carboxylate with aniline and its halogenated analogsin boiling dry xylene. The peculiarities of the mass and nuclear magnetic resonance (¹Н and 13С) spectra of the synthesized compounds are discussed. Usi...

New Pd(II) and Pt(II) complexes of the type [M(bzoS)2(diamine)] {where M = or } from treatment one mole diamine ligands {diamine , phenanthroline (Phen), bipyridine (Bipy), ethylene (en), N,N′-dimethyl (dmen)} with [M(bzoS)2] complexes. The prepared were characterization by elemental analysis (CHN), molar conductivity, infrared spectroscopy, nuclear magnetic resonance proton (1H NMR). bzoS- lig...
