Octanol-supported wooden tips as sustainable devices in microextraction: A closer view of the influence of wood matrix
(Elsevier, 2022)This article describes the use of wooden tips as substrates under a hybrid microextraction format. This format synergically combines the extraction capacities of wood (solid substrate) and an organic solvent (immobilized ... -
On-site extraction of benzophenones from swimming pool water using hybrid tapes based on the integration of hydrophilic-lipophilic balance microparticles and an outer magnetic nanometric domain
(Springer, 2024)An on-site extraction device is presented consisting of scotch tape modified with concentric domains of micrometric hydrophilic-lipophilic balance (HLB) particles surrounded by a ring of nanometric magnetic ones. On the ... -
One-pot synthesis of graphene quantum dots and simultaneous nanostructured self-assembly via a novel microwave-assisted method: impact on triazine removal and efficiency monitoring
(Royal Society of Chemistry, 2018)One-step methods for fabricating green materials endowed with diverse functions is a challenge to be overcome in terms of reducing environmental risk and cost. We report a fast and easy synthesis of multifunctional materials ... -
Optimisation and comparison of several microextraction/methylation methods for determining haloacetic acids in water using gas chromatography
(Springer, 2010)This article presents the different modes and configurations of liquid-phase microextraction (LPME) through comparison with headspace solid-phase microextraction (HS-SPME) for the simultaneous extraction/ methylation of ... -

Pharmacokinetic/pharmacodynamic modeling of benazepril and benazeprilat after administration of intravenous and oral doses of benazepril in healthy horses
(Elsevier, 2017)Pharmacokinetic and pharmacodynamic (PK/PD) properties of the angiotensin- converting enzyme inhibitor (ACEI) benazeprilat have not been evaluated in horses. This study was designed to establish PK profiles for benazepril ... -
Photocatalytic/sorption-self-cleaning activity of cellulose decorated with TiO2 and M@TiO2 (M=Au, Ag) polymeric nanocomposites
(Elsevier, 2024)Titanium oxide nanoparticles (TiO2 NPs) are a semiconductor material widely employed as photocatalysts for environmental remediation owing to its excellent properties. Nevertheless, collecting the nanomaterial once dispersed ... -
Photoionization-ion mobility spectrometer for non-targeted screening analysis or for targeted analysis coupling a Tenax TA column
(Elsevier, 2016)Photoionization-ion mobility spectrometer (UV-IMS) can be used as a screening instrument to distinguish gasoline vapors from other similar samples, obtaining characteristic fingerprints in a quick and simple analysis. A ... -
Polydopamine inner wall-coated hypodermic needle as microextraction device and electrospray emitter for the direct analysis of illicit drugs in oral fluid by ambient mass spectrometry
(Elsevier, 2022)In this article, polydopamine inner wall-coated hypodermic needles (PDA-HNs) are evaluated as both microextraction devices and electrospray ionization (ESI) emitters for determining selected illicit drugs (methamphetamine, ... -
Polymeric nanocomposites as sorbents in environmental water analysis, a close view to the synthesis and potential applications
(Elsevier, 2021)Polymeric nanocomposites have been extensively used as sorbents to extract pollutants from environmental waters before their final instrumental analysis. These materials are highly versatile and can be adapted to a given ... -
Polyvinyl chloride coated paper postmodified by nucleophilic substitution with diphenylamine to enhance cation-π interactions with opioids in saliva samples
(Elsevier, 2024)This article evaluates the potential of cellulose paper as a substrate for preparing a polyvinylchloride (PVC)-diphenylamine sorptive phase that can be used under the thin film microextraction (TFME) format. This phase was ... -
Portable stirring device for the on-site extraction of environmental waters using magnetic hydrophilic-lipophilic balance tape
(Elsevier, 2021)The spatial heterogeneity of environmental systems makes sampling at multiple locations crucial to provide complete and representative information. The on-site application of an extraction technique simplifies the sampling ... -
