Gas Sensing and Half-Metallic Materials Design Using Metal Embedded into S Vacancies in WS2 Monolayers: Adsorption of NO, CO, and O2 Molecules

Eduardo Rangel-Cortés, José Pablo Garcia-Islas, Josue Gutierrez-Rodriguez, Saúl Montes de et autres

The adsorption of CO, NO, and O2 molecules onto Cu, Ag, and Au atoms placed in the S vacancies of a WS2 monolayer was elucidated within dispersion-corrected density functional theory. The binding energies computed for embedded defects into S vacancies were 2.99 …

Substitutional Coinage Metals as Promising Defects for Adsorption and Detection of Gases on MoS2 Monolayers: A Computational Approach

Josue Gutierrez-Rodriguez, Miguel Castro, José Manuel Nieto-Jalil, Dora I. Medina et autres

Defective molybdenum disulfide (MoS2) monolayers (MLs) modified with coinage metal atoms (Cu, Ag and Au) embedded in sulfur vacancies are studied at a dispersion-corrected density functional level. Atmospheric constituents (H2, O2 and N2) and air pollutants (CO and NO), known as secondary …

Bi-dimensional crime model based on anomalous diffusion with law enforcement effect

Francisco Javier Martínez-Farías, Anahí Alvarado-Sánchez, Eduardo Rangel-Cortés, A. Hernández–Hernández

Several models based on discrete and continuous fields have been proposed to comprehend residential criminal dynamics. This study introduces a two-dimensional model to describe residential burglaries diffusion, employing Lèvy flights dynamics. A continuous model is presented, introducing bidimensional fractional operator diffusion and …

Cycloaddition between nitrogen-doped graphene (6π-component) and benzene (4π-component): a theoretical approach using density functional theory with vdW-DF correction

Eduardo Rangel-Cortés, José Alfredo Pescador-Rojas, Víctor A. Cardozo Mata, A. Hernández–Hernández et autres

The interaction between nitrogen-doped graphene defects (N3V1 and N4V2 pyridinic, and N3V1 and N3V3 pyrrolic) and benzene have been investigated by applying density functional theory (DFT), together with the vdW-DF correction. We discovered that only the N3V3 pyrrolic defect is a reactive …

Effect of ultrasonic irradiation power on sonochemical synthesis of gold nanoparticles

Jesús Antonio Fuentes-García, J. Santoyo-Salzar, Eduardo Rangel-Cortés, Gerardo Fabián Goya et autres

In this work, optimized size distribution and optical properties in the colloidal synthesis of gold nanoparticles (GNPs) were obtained using a proposed ultrasonic irradiation assisted Turkevich-Frens method. The effect of three nominal ultrasound (20 kHz) irradiation powers: 60, 150, and 210 W …
