An Overview of the Production of Oxygenated Fuel Additives by Glycerol Etherification, Either with Isobutene or tert-Butyl Alcohol, over Heterogeneous Catalysts
(MDPI, 2019)Biodiesel production has considerably increased in recent decades, generating a surplus of crude glycerol, which is the main drawback for the economy of the process. To overcome this, many scientists have directed their ... -
Análisis arqueométrico de los productos de corrosión de un caldero de bronce de baja época ibérica del Cerro de la Cruz (Almedinilla, Córdoba)
(Museo Histórico Municipal de Priego de Córdoba, 2017)Se estudian una serie de fragmentos de bronce de época ibérica hallados en el Cerro de la Cruz (Almedinilla, Córdoba) para determinar la composición química de los productos de corrosión formados sobre ellos. La caracterización ... -

Application of Enzymatic Extracts from a CALB Standard Strain as Biocatalyst within the Context of Conventional Biodiesel Production Optimization
(MDPI, 2017)The application of biocatalysts in the transesterification process of triglycerides (TG) allows integrating the glycerol in the form of monoglyceride (MG), sharply increasing the yield and the environmental sustainability ... -
Archaeological and Archaeometric Insights into a Roman Wall Painting Assemblage from the Blanes Dump (Mérida)
(MDPI, 2024)In this paper we describe the archaeological and archaeometric analysis of a Third Pompeian Style assemblage from the Blanes dump in Mérida (Spain). Based on the pottery context, the material would have been part of the ... -
Archaeometric identification of a perfume from Roman times
(MDPI, 2023)Although archaeological excavations have recovered a large number of vessels used to hold perfumes or ointments in ancient Rome, little is known about the chemical composition or origin of the substances they contained. ... -
Artificial Coal: Facile and Green Production Method via Low-Temperature Hydrothermal Carbonization of Lignocellulose
(ACS, 2022)A new concept is proposed for the production of artificial coal under HTC conditions using Mg(NO3)2 as an oxidant in a short time, which is found to enhance the coalification degree of hydrochar from lignocellulosic ... -
Autoaprendizaje tutorizado de los estados de la materia. Empleando un software interactivo
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2004)During this academical year, we are testing the new ECTS educational system in some of the Cordoba universitary studies. With this new credit concept, all the work of the students tend to be evaluated. This report presents ... -
Avances en la tecnología de baterías litio-azufre: rendimiento, seguridad y sostenibilidad
(Universidad de Córdoba, UCOPress, 2023)Hasta hace dos siglos, la humanidad vivía sin el uso de combustibles fósiles para cumplir con las necesidades de su día a día. Su base energética era principalmente la energía humana y animal, y los únicos combustibles ... -

Bay leaves extracts as active additive for food protective coatings
(MDPI, 2023)Ethanolic extracts of bay leaves were obtained using the Soxhlet method (extraction yield of 22.3 ± 1.2%) and further analyzed through different methods, thus determining the chemical composition with gas chromatography, ... -
Benign-by-design preparation of iron oxides/humins catalytic nanocomposites
(Royal Society of Chemistry, 2017)The current acid-catalyzed conversion of biomass feedstocks yields substantial quantities of undesired by-products called humins, for which applications are yet to be found. This work aims to provide a starting point for ... -
Bentonites Modified with Phosphomolybdic Heteropolyacid (HPMo) for Biowaste to Biofuel Production
(MDPI, 2019)Two bentonites from Paraíba (Northeastern Brazil) were impregnated with heteropoly phosphomolybdic H3PMo12O40 (HPMo). The materials produced were characterized by various techniques such as N2 adsorption-desorption (specific ... -
Bio-Degradable Polyurethane Foams Produced by Liquefied Polyol from Wheat Straw Biomass
(MDPI, 2020)In the present work, an abundant and unused residue (wheat straw) has been employed to synthesize a polyol as a substituent of castor oil in polyurethane foams. The liquefied product showed excellent properties for the ... -
