13C and 15N solid-state NMR studies on albendazole and cyclodextrin albendazole complexes
(Elsevier, 2015-01)
13C and 15N solid-state nuclear magnetic resonance (NMR) spectra were recorded from albendazole (ABZ) and from ABZ:β-cyclodextrin, ABZ:methyl-β-cyclodextrin, ABZ:hydroxypropyl-β-cyclodextrin and ABZ:citrate-β-cyclodextrin, ...
Structural studies of AgPO3-MoO3 glasses using solid state NMR and vibrational spectroscopies
(Elsevier B.V., 2012-04-01)
Vitreous samples (1-x) AgPO3-x MoO3 (0 <= x <= 0.5) were prepared by conventional melt-quenching and characterized by Differential Scanning Calorimetry (DSC). The structural evolution of the vitreous network was monitored ...
Synthesis and characterization of a platinum(II) complex with N-acetyl-L-cysteine
(Taylor & Francis Ltd, 2009-01-01)
Synthesis and spectroscopic studies in the solid-state of a platinum(II) complex with N-acetyl-L-cysteine are described. Elemental analyses are consistent with composition Pt2(C5H8NO3S)4 center dot 3H2O. Solid-state 13C ...

Solid state NMR as a new approach for the structural characterization of rare-earth doped lead lanthanum zirconate titanate laser ceramics
(ELSEVIER SCIENCE BV, 2008)
To facilitate the design of laser host materials with optimized emission properties, detailed structural information at the atomic level is essential, regarding the local bonding environment of the active ions (distribution ...
Investigating Albendazole Desmotropes by Solid-State NMR Spectroscopy
(American Chemical Society, 2015-03)
Characterization of the molecular structure and physicochemical solid-state properties of the solid forms of pharmaceutical compounds is a key requirement for successful commercialization as potential active ingredients ...
Elucidating the guest-host interactions and complex formation of praziquantel and cyclodextrin derivatives by 13C and 15N solid-state NMR spectroscopy
(Elsevier Science, 2015-12)
Praziquantel is the drug of choice to treat several parasitic infections including the neglected tropical disease schistosomiasis. Due to its low aqueous solubility, cyclodextrins have been tested as potential host candidates ...
NMR study of styrene-butadiene rubber (SBR) and TiO2 nanocomposites
(Elsevier B.V., 2009-08-01)
The chemical behavior of styrene-butadiene rubber (SBR) and of the SBR/TiO2 and photodegraded SBR/TiO2 nanocomposites was investigated through nuclear magnetic resonance spectroscopy (NMR) in the solid state with magic ...
Generation and Stability of the gem-Diol Forms in Imidazole Derivatives Containing Carbonyl Groups. Solid-State NMR and Single-Crystal X-ray Diffraction Studies
(American Chemical Society, 2018-01)
The stability of gem-diol forms in imidazolecarboxaldehyde isomers was studied by solid-state nuclear magnetic resonance (ss-NMR) combined with single-crystal X-ray diffraction studies. These methodologies also allowed ...
