Recent Advances in Extraction and Stirring Integrated Techniques
(MDPI, 2017)The extraction yield of a microextraction technique depends on thermodynamic and kinetics factors. Both of these factors have been the focus of intensive research in the last few years. The extraction yield can be increased ... -
Recycling Oxacillin Residues from Environmental Waste into Graphene Quantum Dots
(MDPI, 2019)Of great concern are the residual antibiotics from dirt that can be found in farm soil and wastewater. This kind of emerging pollutant into engineered nanomaterials is riveting. This work proposes the elimination and ... -
Relationship between Volatile Organic Compounds and Microorganisms Isolated from Raw Sheep Milk Cheeses Determined by Sanger Sequencing and GC–IMS
(MDPI, 2023)Recently, the interest of consumers regarding artisan cheeses worldwide has increased. The ability of different autochthonous and characterized lactic acid bacteria (LAB) to produce aromas and the identification of the ... -
La responsabilidad social de la ciencia y tecnología
(Real Sociedad de Química, 2012)El impacto mutuo de la Ciencia y Tecnología (CyT) y la sociedad/medio ambiente es el tema tratado genéricamente en este artículo. Se considerará la definición de la Responsabilidad Social de la Ciencia y Tecnología tomando ... -
Responsabilidad social: una ruta para alcanzar la excelencia en laboratorios de ensayos y calibraciones
(2013-07-12)Se propone un modelo de gestión estratégico para incluir la gestión de la Responsabilidad Social (RS) como una herramienta que permita no sólo la responsabilidad por la calidad de los resultados y el compromiso con los ... -
Restricted access supramolecular solvents for the simultaneous extraction and cleanup of ochratoxin A in spices subjected to EU regulation
(Elsevier, 2018)A simple and high-throughput sample treatment, based on the use of a supramolecular solvent with restricted access properties (SUPRAS-RAM), was developed for the quantification of ochratoxin A (OTA) in spices subjected ... -
Retos de las mediciones en la nanoescala
(2013-10-16)Se describen los fenómenos que ocurren en las nanodimensiones y la importancia de la Nanometrología para resolver problemas de la sociedad actual. También, se ponen de manifiesto los retos presentes y futuros que tiene la ... -
Returning to Nature for the Design of Sorptive Phases in Solid-Phase Microextraction
(MDPI, 2019)Green analytical chemistry principles aim to minimize the negative impact of analytical procedures in the environment, which can be considered both at close (to ensure the safety of the analysts) and global (to conserve ... -
Ribbon-shaped supramolecular solvents: Synthesis, characterization and potential for making greener the microextraction of water organic pollutants
(Elsevier, 2023)Liquid-liquid microextraction (LLME) techniques have experienced a tremendous growth over the last years but still face major challenges related to the use of more efficient and environmentally friendly solvents. Supramolecular ... -

Screening and confirmatory analysis of glyoxylate: A biomarker of plants resistance against herbicides
(2010)The evidence that glyoxylate is a biomarker of tolerance or susceptibility to the action of herbicides belonging to the glycine family makes necessary to develop simple methods for the determination of this metabolite. ... -
Screening of additives in plastics with high resolution time-of-flight mass spectrometry and different ionization sources: direct probe injection (DIP)-APCI, LC-APCI, and LC-ion booster ESI
(Springer, 2016)Plastics are complex mixtures consisting of a polymer and additives with different physico-chemical properties. We developed a broad screening method to elucidate the nature of compounds present in plastics used in ... -
Silica nanoparticles–nylon 6 composites: synthesis, characterization and potential use as sorbent
(Royal Society of Chemistry, 2017)Composite materials based on the combination of nanoparticles (NPs) and polymers have attracted much attention in recent years thanks to their positive characteristics. In this article an easy, cheap and green procedure ... -
