Fabricación de material de referencia 72a (aleación Cu-Al) utilizando la técnica de aleación mecánica
(2013-11-28)Los materiales de referencia empleados para la técnica de discriminación de energía de rayos X (EDE) requieren que su homogeneidad satisfaga los análisis químicos en regiones de aproximadamente 1 a 3 mm de diámetro, ... -
Facile preparation of carbon nanotube-based molecularly imprinted monolithic stirred unit
(Springer, 2020)A lab-made stirring extraction unit based on a selective monolithic solid was developed. The monolith was formed by interconnected carbon nanotubes which were covered by a thin polymeric layer, where specific cavities were ... -
Feed Supplementation Detection during the Last Productive Stage of the Acorn-Fed Iberian Pig through a Faecal Volatilome Analysis
(MDPI, 2023)The acorn-fed Iberian pig is known worldwide due to the quality of the resulting products commercialized after a natural and free grazing period of fattening in the dehesa agroforestry ecosystem. The quality regulation of ... -
Fluorescent carbon dot–molecular salt hydrogels
(Royal Society of Chemistry, 2015)The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation properties, while ... -
Fomento del trabajo autónomo en las prácticas de laboratorio de alumnos del grado de química: caso de estudio
(UCOPress, 2019)En este estudio se ha perseguido incrementar la participación de los alumnos en las prácticas de laboratorio. El motivo principal ha sido evitar que el alumno memorice los conceptos teóricos sin ser capaz de aplicarlos a ... -
Glycerol photoreforming for photocatalytic hydrogen production on binary and ternary Pt-g-C3N4-TiO2 systems: a comparative study
(Elsevier, 2024)Photocatalytic hydrogen production using two sacrificial agents (triethanolamine and glycerol) was conducted on several binary (Pt/TiO2 and Pt/g-C3N4) and ternary systems (Pt on a heterojunction between TiO2 and g-C3N4 ... -
Glyphosate tolerance by Clitoria ternatea and Neonotonia wightii plants involves differential absorption and translocation of the herbicide
(Springer, 2011)Glyphosate tolerance by Clitoria ternatea, Neonotonia wightii and Amaranthus hybridus was studied in whole plants from Mexico. Experiments in a controlled growth chamber showed both legumes to be highly tolerant of glyphosate, ... -

Guidelines to build PLS-DA chemometric classification models using a GC-IMS method: Dry-cured ham as a case of study
(Elsevier, 2023)chemometric models for class discrimination; therefore, knowing which samples should be used for the calibration of prediction models is essential. The aim of this work is to design a basic guideline for the training of ... -
Haloacetic Acids in Swimming Pools: Swimmer and Worker Exposure
(ACS Publications, 2011)For the first time, the exposure of swimmers and workers to haloacetic acids (HAAs) in indoor and outdoor pools was evaluated through the analysis of urine samples. The subjects of this study, 49 volunteers, were male and ... -
Halogen bonding for increasing efficiency in liquid-liquid microextraction: Application to the extraction of hexabromocyclododecane enantiomers in river water
(Elsevier, 2019)Halogen bonding (XB) was here proposed, for the first time, as a solubilization mechanism for increasing efficiency in the liquid-liquid microextraction of halogenated compounds. The approach was illustrated by the ... -
Hemimicelles of Alkyl Carboxylates Chemisorbed onto Magnetic Nanoparticles: Study and Application to the Extraction of Carcinogenic Polycyclic Aromatic Hydrocarbons in Environmental Water Samples
(ACS, 2009)In this work, magnetic nanoparticles (MNPs) coated with hemimicelles of alkyl (C10-C18) carboxylates, which have traditionally been used to prepare ferrofluids for technological applications, were used for the first time ... -
Identification of impurities of phosphate and brominated flame retardants
(2018)In the last years, new flame retardants (FRs) have been identified for the first time in products and in environmental samples by using mainly liquid chromatography coupled to high resolution mass spectrometry. For example, ... -
