<p>PSresins have arisen in the past years as a promising material for the measurement of radioactivity. PSresins are a</p><p>material composed of a PSm support coated with a selective extractant on its surface, allowing ...
The one-pot synthesis of butyl levulinate from fructose and 1- butanol has been optimized using the ion-exchange resin Dowex 50Wx2 as a catalyst in a batch reactor. The effects of temperature (120−150 °C), initial quantity ...
Background: Analyzing mixtures of radionuclides is a complex task. Two situations are the mixtures of 89Sr with 90Sr and 90Sr with plutonium isotopes. The challenge arises in emergency scenarios resulting from accidents ...
Durante años, la determinación de una gran variedad de contaminantes orgánicos persistentes halogenados se ha llevado a cabo mediante el acoplamiento GC-MS, utilizando generalmente técnicas de ionización de alto vacío, com ...
In this study, a ZIC-HILIC-MS methodology for the analysis of N-glycan isomers was optimized to obtain greater detection sensitivity and thus identify more glycan structures in hAGP. In a second step, this method was ...
Early-life exposure to environmental contaminants, such as endocrine disrupting persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorine ...
Background Ambient Mass Spectrometry (AMS) encompasses a group of techniques that have emerged as powerful strategies for direct, in-situ and high-throughput analysis, also in compliance with the principles of green ...
This study aimed to improve the understanding of the nutrient modulation of Ostreopsis cf. ovata toxin content. During the 2018 natural bloom in the NW Mediterranean, the total toxin content (up to ca. 57.6 ± 7.0 pg toxin ...
Characterization of the selectivity of HPLC columns is an essential need in many chromatographic development methods. Different tests and procedures have been developed for this purpose. In this paper, we analyze two of ...
This study presents a fast method for the characterization of solute-solvent interactions in micellar and microemulsion electrokinetic chromatography based on the linear solvation energy relationships proposed by Abraham. ...
Chronic inflammation is a significant contributor to various diseases but its assessment via blood sampling presents challenges, particularly in children. The evaluation of urinary biomarkers, including 3-bromotyrosine ...
Granular Activated Carbon (GAC) is commonly used in water treatment for the removal of Dis-solved Organic Matter (DOM) and diminution of the formation of Disinfection By-Products (DBP)during final disinfection. The aim of ...
High resolution mass spectrometry (HRMS) has undergone an exciting phase of technological evolution. Time of flight instruments with significantly higher resolution and larger dynamic range have become available. Furthermore, ...
Cinnamon is a widely marketed spice used in worldwide cuisines and medicinal applications. Although Cinnamomum verum is considered as “true cinnamon”, other cinnamon species (particularly Cinnamomum cassia) are also ...
Cinnamon is one of the most popular spices used in cuisines worldwide. Among its different species, Ceylon cinnamon (“true cinnamon") is the one with the most health benefits due to its high concentration in the antioxidant ...
The process optimization of 4,4-bipyridine based metal organic framework (MOF) synthesis by twin screw extrusion (TSE) is investigated using cobalt nitrate hexahydrate (Co(NO3)2·6H2O) as the metal precursor. The effects ...
The self-organization of microbes into biofilms provides multiple benefits including tolerance to mechanical stress and resistance to immune defences and antibiotics. Coupled to a compromised mucociliary function, these ...
This study examined total ammoniacal nitrogen (TAN) rejection by two reverse osmosis (RO) and two nanofiltration (NF) membranes as a function of pH for three ammonium salts to optimize conditions for a hybrid membrane ...
A new series of styryl hemicyanine dyes featuring substituted N-phenylpiperazine end groups was synthesized using an environmentally friendly procedure. The photophysical properties of the dyes were systematically investigated ...
Elucidating the factors affecting the transfer of naturally occurring radionuclides (NOR) between environmental compartments is a key part of the assessment of ecosystem's exposure to naturally occurring radionuclide ...
