Synthesis and spectroscopic characterization of cyclobutyl hydantoins
(Elsevier Science, 2018-11-01)
The hydantoin moiety has proved to be an important pharmacophore that confers a wide range of biological properties to different derivatives. Thus, synthetic methods have been developed to obtain such molecules. Herein, ...

Structural analysis of natural deep eutectic solvents : theoretical and experimental study
(Elsevier Science, 2018-12)
A theoretical and experimental study was performed on natural deep eutectic solvents (NADES) formed by lactic acid-glucose (LGH), citric acid-fructose (CFH) and citric acid-glucose (CGH). The presence of nuclear Overhauser ...
Probing Surface Effects on α-NaYF4 Nanoparticles by Nuclear Magnetic Resonance
(American Chemical Society, 2020-04)
The structural properties of insulating α-NaYF4 (cubic) nanoparticles with size ranging within 4-25 nm were investigated by high-resolution 23Na and 19F solid-state nuclear magnetic resonance (NMR) spectroscopy under magic ...
Challenges in Identifying the Dark Molecules of Life
(Annual Reviews, 2019-03)
Metabolomics is the study of the metabolome, the collection of small molecules in living organisms, cells, tissues, and biofluids. Technological advances in mass spectrometry, liquid- and gas-phase separations, nuclear ...
Paclitaxel/β-Cyclodextrin interactions, a perspective from pulsed NMR spectroscopy experiments
(Elsevier, 2019-10)
Cyclodextrins are cyclic cone shaped oligosaccharides. A guest molecule can be incorporated into the hydrophobic inner of the cyclodextrin to form non-covalent complexes. The formation of these complexes in general, increases ...
Sedimentary rock porosity studied by electromagnetic techniques: nuclear magnetic resonance and dielectric permittivity
(Springer, 2014-11)
The present work involves a comprehensive experimental study of porosity and pore size distribution of sedimentary rocks, from oil fields formations, by means of two electromagnetic techniques, namely proton (1H) nuclear ...
