Se construyó un cuestionario para la medición de los procesos de cambio propuestos por el Modelo Transteórico (MTT), aplicados al consumo de alcohol en estudiantes de secundaria y estudiantes universitarios de Bogotá ...
Hydration behaviour of polyhydroxylated fullerenes
(2011)
We have performed semi-empirical as well as density functional theory calculations in order to analyse the hydration properties of both bare C 60 and highly hydroxylated C60(OH)26 fullerenes. In all of our calculations, a ...
Effect of Mn in ZnO using DFT calculations: Magnetic and electronic changes
(Elsevier Science Sa, 2019-07)
First principles calculations based on density functional theory (DFT)implemented in the VASP code was applied to study the structural, electronic and magnetic properties of ZnO and Mn-doped ZnO. Lattice parameters, bond ...
Atypical antioxidant activity of non-phenolic amino-coumarins
(Royal Society of Chemistry, 2018-01)
Coumarin compounds have been described as anti-inflammatories, and chemotherapeutic agents as well as antioxidants. However, the origin of the antioxidant activity of non phenolic coumarins remains obscure. In the present ...
The Missing Link in the Magnetism of Hybrid Cobalt Layered Hydroxides: The Odd‐Even Effect of the Organic Spacer
(Wiley VCH Verlag, 2020-08)
A dramatic change in the magnetic behaviour, which solely depends on the parity of the organic linker molecules, has been found in a family of layered CoII hydroxides covalently functionalized with dicarboxylic molecules. ...
