A rapid method for interfacial tension calculation between rock plug and crude oil based on contact angles, application for EOR
(Taylor & Francis, 2018)"Interfacial tension and contact angle are two specific important parameters to take decisions for enhanced oil recovery, for instance, proper chemicals to use for surface tension reduction, expected wettability of solids, ... -
A Switching Controller for a Class of MIMO Bilinear Systems With Time Delay
(IEEE, 2020)"In this paper we propose a switching controller for a class of MIMO bilinear systems with constant delays in both the state and the input. The motivation to consider such a class of systems is that, in the scalar case, ... -
Absence of evidence is not evidence of absence: Multiple steady states in ammonia synthesis
(Elsevier, 2016)"Using a chemical reaction network (CRN) Theory approach, three well-accepted mechanisms of ammonia synthesis over iron catalyst taking place within an isothermal Continuous Flow Stirred Tank Reactor (CFSTR) are analyzed. ... -
Adsorbentes híbridos oxihidróxidos metálicos-carbón para remover contaminantes prioritarios del agua: fluoruro y arsénico
(2015)"La contaminación del agua por fluoruros (F- ) y arsénico (As) es un problema de importancia mundial, ya que el agua subterránea de varios países excede los límites permisibles establecidos por la Organización Mundial de ... -
Anaerobic arsenotrophy linked to iron and sulfur biotransformations: implications on the fate of arsenic in solid-liquid interfaces
(2020-03-17)"Arsenic (As) is a metalloid classified in the heavy metal group as it can induce toxicity at low concentrations (µg/L). On a global scale, the recognition of arsenic as a priority pollutant derives from its occurrence in ... -

(2017-11)"En la presente tesis se estudia el arresto cinético de la transformación martensítica en aleaciones Heusler no estequiométricas de composición nominal Ni50Mn36In14 y Ni45Co5Mn36.8In13.2, así como el efecto magnetocalórico ... -
Bioreactores empacados con fibras de carbón activado como mediadores redox en la biotransformación anaerobia de 4-Nitrofenol hacia 4-Aminofenol
(2017)"La función de los grupos funcionales superficiales sobre los carbones activados es de gran interés en procesos biológicos con actividad redox porque tales grupos pueden incrementar la eficiencia de biotransformación de ... -
Carbamazepine degradation by visible-light-driven photocatalyst Ag3PO4/GO: Mechanism and pathway
(Elsevier, 2022)"Carbamazepine (CBZ), as one of the most frequently detected pharmaceuticals, is of great concern due to its potential impact on the ecosystem and human health. This study provides an effective approach to remove CBZ by ... -
Cellular automata modeling of continuous stirred tank reactors
(2008)"The classical dynamical systems model of continuous stirred tank reactors (CSTR) in which a first order chemical reaction takes place is reformulated in terms of stochastic cellular automata by extending previous works of ... -
Cinética de captura de CO2 en fibras de bagazo de agave carbonizadas e impregnadas con el líquido iónico acetato de 1-butil-3-metilimidazol
(2019)"El uso de combustibles fósiles aumenta las concentraciones de CO2 en la atmósfera, situación que causa efectos negativos al ambiente, sin embargo, es importante considerar que existen procesos industriales que requieren ... -
Co-production of ethanol-hydrogen by genetically engineered Escherichia coli in sustainable biorefineries for lignocellulosic ethanol production
(Elsevier, 2021)"This work shows the impact of the hydrogen and ethanol co-production –via dark fermentation– using a genetically engineered Escherichia coli in the environmental and economic sustainability of a lignocellulose-based ... -
Covalently bonded three-dimensional carbon nanotube solids via boron induced nanojunctions
(2012)"The establishment of covalent junctions between carbon nanotubes (CNTs) and the modification of their straight tubular morphology are two strategies needed to successfully synthesize nanotube-based three-dimensional (3D) ... -
Deforestation impacts on bat functional diversity in tropical landscapes
(2016-12)"Functional diversity is the variability in the functional roles carried out by species within ecosystems. Changes in the environment can affect this component of biodiversity and can, in turn, affect different processes, ... -
