Two new asymmetric monomethine cyanine dyes, featuring dimethoxy quinoliniumor methyl quinolinium end groups and benzothiazole or methyl benzothiazole endgroups were synthesized. The chemical structures of the two ...
Un problema recurrente en los estudios de Química es la dificultad que presenta el estudiantado para relacionar los conceptos teóricos con las aplicaciones prácticas y viceversa. En este trabajo se muestra el desarrollo ...
Fluoroquinolone antibiotics (FQs) are of concern due to their disrupting effects on environmental bacterial communities. Evaluating FQ sorption by soil components is important to understand their interaction with soils and ...
A polymeric ion-exchange resin, incorporating methyl-amino-phosphonic (TP260) functionalities, and a solvent impregnated resin (SIR) incorporating tri-methylpentylphosphinic acid (TP272), were evaluated for the selective ...
In recent years, bisphenol A has been progressively replaced by other bisphenol analogues, leading to an increase of their occurrence in aquatic environments. However, limited data is available regarding their removal ...
Liquid Scintillation has two main characteristics: the lack of resolution and the capability to determine alpha and beta emitters. Society evolves toward a situation where information is key for management and where ...
Oligomerization of 1-octene is a feasible alternative to improve the properties and the quality of fuels and lubricants oils. The performance of macroreticular ion-exchange resins as catalysts for such reaction has been ...
In this paper we describe a strategy to estimate by CE the acidity constants (pKa) of complex polyprotic peptides from their building peptide fragments. CE has been used for the determination of the pKas of five short ...
The enzyme PARP1 is an attractive target for cancer therapy, as it is involved in DNA repair processes. Several PARP1 inhibitors have been approved for clinical treatments. However, the rapid outbreak of resistance is ...
A short discussion is given of the convenience of integrating electrochemistry and chemometrics in university degrees related to chemistry, and some selected examples are presented to illustrate the possibilities of combining ...
A hybrid material (nano-metal organic framework@organic polymer, named as nano-MOF@polymer) was applied for the first time as sorbent for on-line solid-phase extraction capillary electrophoresis with ultraviolet detection ...
The solubility of amphotericin B (AmB) has been studied between temperatures of 298-343 K in a range of pure organic solvents including methanol, ethanol, isopropanol, butanol, acetone, tetrahydrofuran, and 1,4-dioxane. ...
Formation of extractive-rich heartwood is a process in live trees that make them and the wood obtained from them more resistant to fungal degradation. Despite the importance of this natural mechanism, little is known about ...
Three different commercial carbon nanomaterial-modified screen-printed electrodes based on graphene, carbon nanotubes and carbon nanofibers were pioneeringly tested as electrode platforms for the plating with Sb film. They ...
In this work, the performances of ozonation, photolytic ozonation (UV-C/O3), and photocatalytic ozonation (UV-A/TiO2/O3) in degrading ozone recalcitrant micropollutants in four different real domestic wastewaters were ...
El aprendizaje basado en problemas (ABP) consiste en utilizar problemas como elemento clave para la adquisición e integración de nuevos conocimientos. Esta metodología se centra en los estudiantes e implica trabajo ...
PSresins have arisen in the past years as a promising material for the measurement of radioactivity. PSresins are a material composed of a PSm support coated with a selective extractant on its surface, allowing the separation ...
Background Esophageal cancer (EC) is a malignancy with a poor prognosis and a five-year survival rate of less than 20%. It is the ninth most frequent cancer globally and the sixth leading cause of cancer-related deaths. ...
A non-targeted LC-HRMS fingerprinting methodology using an Orbitrap mass analyzer, and based on C18 reversed-phase mode under universal gradient elution, was developed to characterize and classify Spanish honey samples. A ...
The determination of polyphenols in wines is of great interest in the field of food analysis due to health and organoleptic implications. In addition, the applicability of polyphenols as food descriptors to be used for ...
