A Sensor-Based Methodology to Differentiate Pure and Mixed White Tequilas Based on Fused Infrared Spectra and Multivariate Data Treatment
(MDPI, 2021-02-27)[Abstract]: Mexican Tequila is one of the most demanded import spirits in Europe. Its fast-raising worldwide request makes counterfeiting a profitable activity affecting both consumers and legal distillers. In this paper, ... -
A Simple Method for the Determination of Triazines from Seawater in Accordance with the Directive 2013/39/EU
(Springer Nature, 2020-06-09)[Abstract] Since the Directive 2013/39/EU included terbutryn to the list of priority substances of all water bodies, a previous method based on dispersive liquid–liquid micro-extraction (DLLME) for the determination of ... -
A Simple Procedure to Select a Model for Mass Discrimination Correction in Isotope Dilution Inductively Coupled Plasma Mass Spectrometry
(Royal Society of Chemistry, 2015-05)[Abstract] A fast, simple and straightforward procedure to decide on the best model to calculate the mass discrimination factor in Isotope Dilution Inductively Coupled Plasma Mass Spectrometry (ID-ICP-MS) is proposed. ... -
A Synthetic Quality Index to Evaluate the Functional Stability of Soil Microbial Communities After Perturbations
(Elsevier, 2021-05-28)[Abstract] Soil stability includes both resistance, the ability to withstand a perturbation or stress, and resilience, the ability to recover to pre perturbation levels. The functional stability of soil microbial communities ... -
Adsorption of Pesticides and Personal Care Products on Pristine and Weathered Microplastics in the Marine Environment. Comparison Between Bio-Based and Conventional Plastics
(Elsevier, 2022)[Abstract] The hydrophobicity of persistent organic pollutants (POPs) makes them adsorb on microplastics in the marine environment, affecting their distribution, persistence, or their transfer to the trophic chain. Fragrances ... -
Comparative Study of Atmospheric Water-Soluble Organic Aerosols Composition in Contrasting Suburban Environments in the Iberian Peninsula Coast
(Elsevier, 2019-01-15)[Abstract] This study investigates the structural composition and major sources of water-soluble organic matter (WSOM) from PM2.5 collected, in parallel, during summer and winter, in two contrasting suburban sites at Iberian ... -
Comparison of Microplastic Type, Size, and Composition in Atmospheric and Foliage Samples in an Urban Scenario
(Elsevier, 2024-04-17)[Abstract] The rising trend of plastic production in last years and the inadequate disposal of related waste has raised concerns regarding microplastic-related environmental issues. Microplastic particles disperse by means ... -
Determination of Antioxidant Activity by in Situ Synthesis of AgNPs Using In-Tube SPME Coupled On-Line to Capillary Liquid Chromatography
(Springer Nature, 2023-07-18)[Abstract] A chromatographic system based on in-tube SPME coupled to capillary LC-DAD has been used to study the synthesis of silver nanoparticles using polyphenols in different scenarios: excess of the reducing agent or ... -
