Selective hydrogenation of acetylene to ethylene: Performance of a Pt monolayer over an α-WC(0001) surface for binding and hydroconversion of acetylene
Ethylene (C2H4) is a useful hydrocarbon in polymerization reactions and as a probe system to understand hydrogenation reactions of complex unsaturated hydrocarbons and olefins. However, C2H4 streams usually contain small ...
DFT analysis of phosphorene and oxidized phosphorene as Cu2+ adsorbent materials from aqueous solution [Análisis DFT de fosforeno y fosforeno oxidado como materiales adsorbentes de Cu2+ a partir de una solución acuosa]
We conducted a systematic study using the density functional theory (DFT) to provide a better understanding of the role of oxygen concentration in pristine phosphorene during Cu2+ adsorption in aqueous systems. The electronic ...
Communication and Living Well: Educommunication in Collectives from the Peripheries of Colombia and Brazil [Comunicação e Bem-Viveres: Educomunicação em Coletivos das Periferias de Colômbia e Brasil]
We present an academic and reflexive dialogue of two investigations: “Communication and Well-Living (or Good Living) in the territory” and “Popular and Peripheral Educommunication in Latin America: Dialogues of knowledges ...
Multi-Variate Risk Measures under Wasserstein Barycenter
When the uni-variate risk measure analysis is generalized into the multi-variate setting, many complex theoretical and applied problems arise, and therefore the mathematical models used for risk quantification usually ...
Effect of nanostructuring on the interaction of CO2 with molybdenum carbide nanoparticles
Transition metal carbides are increasingly used as catalysts for the transformation of CO2 into useful chemicals. Recently, the effect of nanostructuring of such carbides has started to gain relevance in tailoring their ...
Literature as a form of elaboration. Analysis of El olvido que seremos, by Héctor Abad Faciolince [La literatura como forma de elaboración. Análisis de El olvido que seremos, de Héctor Abad Faciolince]
From a presentation of the contrast between the literature of violence and contemporary literature on violence, this article proposes the analysis of El olvido que seremos, by Héctor Abad Faciolince, in light of the ideas ...
Suicidal risk and strategies for coping with stress in Colombian rural population [Riesgo suicida y estrategias de afrontamiento al estrés en población campesina colombiana]
Introduction: Suicidal behavior refers to the various behaviors to stop living, it is a multifactorial phenomenon widely studied in the urban population, however, the rural population, especially farmers and agricultural ...
Contribution to the characterization of the Nevado del Ruiz geothermal conceptual model based on rock properties dataset
The assessment of the geothermal resources available in a specific area requires a detailed knowledge of the thermal and hydraulic properties of host rock formations. These properties were quantified with rock samples ...
A Wavelet Analysis of the Dynamic Connectedness among Oil Prices, Green Bonds, and CO2 Emissions
Wavelet power spectrum (WPS) and wavelet coherence analyses (WCA) are used to examine the co-movements among oil prices, green bonds, and CO2 emissions on daily data from January 2014 to October 2022. The WPS results show ...
