Formation of H2on polycyclic aromatic hydrocarbons under conditions of the ISM: an ab initio molecular dynamics study (2024)
Barrera, Nicolás F.; Fuentealba, Patricio; Muñoz, Francisco; Gómez, Tatiana; Cárdenas, Carlos (Oxford University Press, 2023)Understanding how the H2 molecule is formed under the chemical conditions of the interstellar medium (ISM) is critical to the whole chemistry of it. Formation of H2 in the ISM requires a third body acting as a reservoir ... -

Links among the Fukui potential, the alchemical hardness and the local hardness of an atom in a molecule (2021)
Gómez, Tatiana; Fuentealba, Patricio; Robles-Navarro, Andrés; Cárdenas, Carlos (John Wiley and Sons Inc, 2021)This paper presents a brief summary of the difficulty that resides in the definition of the elusive concept of local chemical hardness. We argue that a definition of local hardness should be useful to a reactivity principle ... -

Mechanical and antimicrobial polyethylene composites with CaO nanoparticles (2020)
Silva, Cristián; Bobillier, Felipe; Canales, Daniel A.; Sepúlveda, Francesca; Cament, Alejandro; Amigó, Nicolás; Rivas, Lina María; Ulloa, María Teresa; Reyes-Contreras, Pablo; Ortiz, J. Andrés; ... (MDPI AG, 2020-09-18)Low-density polyethylene composites containing different sizes of calcium oxide (CaO) nanoparticles were obtained by melt mixing. The CaO nanoparticles were synthesized by either the sol-gel or sonication methods, obtaining ... -

Molecular interactions from the density functional theory for chemical reactivity: Interaction chemical potential, hardness, and reactivity principles (2024)
Miranda-Quintana, Ramón Alain; Heidar-Zadeh, Farnaz; Fias, Stijn; Chapman, Allison E. A.; Liu, Shubin; Morell, Christophe; Gómez, Tatiana; Cárdenas, Carlos; Ayers, Paul W. (Frontiers Media S.A., 2022)In the first paper of this series, the authors derived an expression for the interaction energy between two reagents in terms of the chemical reactivity indicators that can be derived from density functional perturbation ... -

Molecular Interactions From the Density Functional Theory for Chemical Reactivity: The Interaction Energy Between Two-Reagents (2024)
Miranda-Quintana, Ramón Alain; Heidar-Zadeh, Farnaz; Fias, Stijn; Chapman, Allison E. A.; Liu, Shubin; Morell, Christophe; Gómez, Tatiana; Cárdenas, Carlos; Ayers, Paul W. (Frontiers Media S.A., 2022)Reactivity descriptors indicate where a reagent is most reactive and how it is most likely to react. However, a reaction will only occur when the reagent encounters a suitable reaction partner. Determining whether a pair ... -

On the Prediction of Lattice Energy with the Fukui Potential: Some Supports on Hardness Maximization in Inorganic Solids (2024)
Kaya, Savaş; Robles-Navarro, Andrés; Mejía, Erica; Gómez, Tatiana; Cardenas, Carlos (American Chemical Society, 2022)Using perturbation theory within the framework of conceptual density functional theory, we derive a lower bound for the lattice energy of the ionic solids. The main element of the lower bound is the Fukui potential in the ... -

Removal of Mo(VI), Pb(II), and Cu(II) from wastewater using electrospun cellulose acetate/chitosan biopolymer fibers (2024)
Lopez, Esmeralda; Gómez, Mauricio; Becar, Ian; Zapata, Paula; Pizarro, Jaime; Navlani-García, Miriam; Cazorla-Amorós, Diego; Presser, Volker; Gómez, Tatiana; Cárdenas, Carlos (Elsevier B.V., 2024)Environmentally friendly polymers such as cellulose acetate (CA) and chitosan (CS) were used to obtain electrospun fibers for Cu2+, Pb2+, and Mo6+ capture. The solvents dichloromethane (DCM) and dimethylformamide (DMF) ...
