A new Valorization Route of Petrochemical Wastewater: Recovery of Phenolic Derivatives and their Subsequent Application in a PP Matrix for the Improvement of their Durability in Multiple Applications
Hernandez-Fernandez, Joaquín; Marulanda, Karen; Puello-Polo, Esneyder (Cartagena de IndiasCampus Tecnológico, 2023-02-16)Wastewater from industrial processes contains different compounds that can be of great use to improve its circularity. The potential of wastewater can be exploited by applying extraction techniques to obtain compounds of ... -
Characterization of Microplastics in Total Atmospheric Deposition Sampling from Areas Surrounding Industrial Complexes in Northwestern Colombia
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Trilleras, Jorge (Cartagena de Indias, 2022)In this study, the total atmospheric deposition of microplastics in places near an industrial complex in Cartagena, Colombia is evaluated by taking samples at three points at different distances from the industrial zone. ... -
Characterization of the Morphological and Chemical Profile of Different Families of Microplastics in Samples of Breathable Air
Hernandez-Fernandez, Joaquín; Puello-Polo, Esneyder; Castro-Suarez, John R (Cartagena de IndiasCampus Tecnológico, 2023-01-20)Microplastic (MP) contamination has become a problem of great interest to the community at large.

Effect of Addition of Polyurea as an Aggregate in Mortars: Analysis of Microstructure and Strength
Chacon, Hernan; Cano, Heidis; Hernández Fernández, Joaquin; Guerra, Yoleima; Puello-Polo, Esneyder; Ríos-Rojas, John Fredy; Ruiz, Yolima (Cartagena de Indias, 2022)The addition of polymers in construction is a new tendency and an important step toward the production of structures with better functional properties. This work investigates the addition of polyurea (PU) as a polymeric ... -
Effects of Different Concentrations of Arsine on the Synthesis and Final Properties of Polypropylene
Hernández Fernández, Joaquin; Guerra, Yoleima; Puello-Polo, Esneyder; Marquez, Edgar (Cartagena de Indias, 2022-07-31)This article studies the effects of arsine on the synthesis and thermal degradation of 4 sam ples of virgin polypropylene (PP-virgin) and proposes reaction mechanisms that allow understanding of its behaviour. Different ... -
Experimental–Density Functional Theory (DFT) Study of the Inhibitory Effect of Furan Residues in the Ziegler–Natta Catalyst during Polypropylene Synthesis
Hernández Fernández, Joaquin; Puello-Polo, Esneyder; Marquez, Edgar (Cartagena de IndiasCampus Tecnológico, 2023-09-21)In this experimental–theoretical study, the effect of furan on Ziegler–Natta catalyst produc tivity, melt flow index (MFI), and mechanical properties of polypropylene were investigated. Through the analysis of the global ... -
Furan as Impurity in Green Ethylene and Its Effects on the Productivity of Random Ethylene–Propylene Copolymer Synthesis and Its Thermal and Mechanical Properties
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Márquez, Edgar (Cartagena de Indias, 2023)The presence of impurities such as H2S, thiols, ketones, and permanent gases in propylene of fossil origin and their use in the polypropylene production process affect the efficiency of the synthesis and the mechanical ... -
Identifying, Quantifying, and Recovering a Sorbitol-Type Petrochemical Additive in Industrial Wastewater and Its Subsequent Application in a Polymeric Matrix as a Nucleating Agent
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Marquez, Edgar (Cartagena de Indias, 2023)Currently, polypropylene (PP) is highlighted using sorbitol-based clarifying agents since these agents are high quality, low cost, and work as a barrier against moisture, which makes PP ideal for packaging food, beverages, ... -
