PICVib: an accurate, fast and simple procedure to investigate selected vibrational modes and...

Phys. Chem. Chem. Phys. 2014, 16, 17670-17680
The generalization of the PICVib approach for calculating infrared intensities was tested and validated for very diverse molecular systems. The PICVib shows an excellent overall performance for calculating infrared intensities of localized normal modes and even mixed vibrations, whereas care must be taken for vibrations involving intermolecular interactions.

Assessment of density-functionals for describing the X + CH3ONO2 gas-phase reactions...

Phys. Chem. Chem. Phys. 2014, 16, 26769-26778 (Author)
The energetics of the ECO2 and SN2 channels of these reactions were computed. This benchmark serve to ascertain the accuracy and robustness of nineteen DFT methods for describing PEP and kinetics. Assessments were based several statistical criteria. Double-hybrid functionals perform better than the range-separated ones, and both are better than the global-hybrids. B2GPPLYP is the most accurate and robust and B2PLYP provide the correct conclusion concerning the nonstatistical behavior.

Estudio fitoquímico y control de calidad de extractos de hojas de Rheedia aristata Griseb.

Rev. Cubana Plant. Med. 2013, 18(3), 361-367 (Co-author)
La tintura 20 % y el extracto fluido de las hojas de Rheedia aristata son formulados ricos en metabolitos secundarios, que pudieran ser los principios activos responsables del uso como medicamento, reportado en estudios etnobotánicos. Esto, unido a la gran estabilidad que muestran y a la no existencia de reportes de toxicidad, convierten a esta planta en fuente potencial de fitomedicamentos.

Chemical composition and antibacterial activity of the essential oil from Eucalyptus pellita F...

J. Med. Plants Res. 2014, 7(27), 1979-1983 (Author)
The essential oil from leaves of Eucalyptus pellita F. Muell was obtained by the hydrodistillation method and forty-three compounds in quantities higher than 0.02% were detected by gas chromatography/mass spectrometry analysis. The essential oil was active against all tested microorganisms with inhibition zone diameters from 8 to 24 mm; although a high activity (effective) against Gram-positive strains was observed.
