Nanopartículas hidrofóbicas magneticamente confinadas
(Universidad de Córdoba, 2013)
Tunable Polarity Carbon Fibers, a Holistic Approach to Environmental Protection
(MDPI, 2018)
The pollution of environmental resources is an issue of social concern worldwide.
Chemistry is essential for the design of decontamination strategies and analytical approaches to
detect and monitor the contamination. ...
Effervescence-Assisted Microextraction—One Decade of Developments
(MDPI, 2020)
Dispersive microextraction techniques are key in the analytical sample treatment context as they combine a favored thermodynamics and kinetics isolation of the target analytes from the sample matrix. The dispersion of the ...
Monolithic Solid Based on Single-Walled Carbon Nanohorns: Preparation, Characterization, and Practical Evaluation as a Sorbent
(MDPI, 2018)
A monolithic solid based solely on single walled carbon nanohorns (SWNHs) was prepared
without the need of radical initiators or gelators. The procedure involves the preparation of a wet
jelly-like system of pristine ...
Magnetic Graphene Oxide Composite for the Microextraction and Determination of Benzophenones in Water Samples
(MDPI, 2020)
Magnetite nanoparticles (Fe3O4) functionalized with graphene oxide (GO) have been synthesized through a silanization process of the magnetic nanoparticles with tetraethyl orthosilicate and (3-aminopropyl)triethoxysilane ...
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 ...
Magnetic Polyamide Nanocomposites for the Microextraction of Benzophenones from Water Samples
(MDPI, 2019)
In this article, the influence of the monomers on the extraction efficiency and the effect of the addition of surfactants during the synthesis have also been considered. The sorption capacity of the resulting nanocomposites ...
Carbon Nanohorn Suprastructures on a Paper Support as a Sorptive Phase
(MDPI, 2018)
This article describes a method for the modification of paper with single-wall carbon
nanohorns (SWCNHs) to form stable suprastructures. The SWCNHs form stable dahlia-like
aggregates in solution that are then self-assembled ...
Determination of the Three Main Components of the Grapevine Moth Pest Pheromone in Grape-Related Samples by Headspace-Gas Chromatography- Mass Spectrometry
(MDPI, 2017)
The grapevine moth (Lobesia botrana) is the most significant pest of viticulture.
This article reports the development of an analytical method that allows the instrumental
determination of the three main pheromone ...
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 ...
