Achievement of analytical chemistry competency needs to be optimized through the application of active learning models. This research aims to design an active learning model oriented towards green chemistry with virtual ...

In this article we describe the application of lipases in acylation and alcoholysis reactions on steroids and nucleosides. In the field of steroids, a variety of acetyl and fatty acid derivatives of androstanes, pregnane...

This review article points out, through an overview, aspects that are related to the procedures established by green analytical chemistry, for the extraction of bioactive compounds in plants, through the use of assisted ...

Abstract Background Healthcare laboratories play a critical role in patient care but contribute substantially to environmental impact due to high consumption of energy, water, and chemicals, as well as the generation of ...

A sustainable photocatalytic protocol for the trifluoromethylation of (hetero)arenes is reported. The method operates under metal- and base-free conditions using an inexpensive and atom-efficient CF3 source, trifluoroace...

Abstract A selective and eco-friendly spectrophotometric approach was developed for the quantitative determination of entacapone (ENT) in the presence of its co-formulated drugs carbidopa (CAR) and levodopa (LEV) which e...

Abstract This study examines the influence of divisor selection on the efficacy of advanced analytical spectrophotometric methods that integrate artificial intelligence (AI), green-chemistry principles, and white-analyti...

Abstract Owing to the widespread usage of synthetic dyes, water contamination prompted by these materials has led to a severe menace on aquatic ecosystem and also on living organisms health. Chitosan modified with cyanog...

A green and sustainable approach to the direct synthesis ofthioesters has been developed using Fe3O4 as a low-cost, easilyprepared, reusable and environmentally safe catalyst. The crossdehydrogenative coupling (CDC) of v...

Water quality in the Paso Piedras Reservoir has deteriorated, primarily due to periodic blue-green algal blooms, making it temporarily unfit for human consumption. This phenomenon results from the eutrophication of water...

Quinolines are well-established scaffolds in drug discovery and form the core of many FDA-approved medicines. Among their reduced analogues, hexahydroquinolines (HHQs) have gained increasing attention due to their struct...

The extensive reliance on fossil resources for fuels and platform chemicals has raised critical concerns over resource depletion and increasing greenhouse gas emissions. To address these challenges, microalgae offer a pr...

Abstract In this study, we reported the synthesis and characterization of a novel magnetic polystyrene nanocatalyst functionalized with L-glutamine (L-Glu-MPS) and evaluation of its catalytic performance in a multicompon...

Applications of metal oxide nanoparticles in the agriculture sector are being extensively included as the materials are considered superior. In the present work, zinc oxide nanoparticle (ZnO NPs), with a developing ferti...

Abstract A novel, eco-friendly spectrofluorimetric method has been developed for the sensitive determination of capivasertib, based on resonance Rayleigh scattering enhancement. Unlike previously reported methods, this a...

A systematic Analytical Quality by Design (AQbD) approach was applied to the development and validation of a UHPLC–MS/MS method for the determination of hallucinogenic phenethylamine-derived novel psychoactive substanc...

Abstract An innovative, sustainable analytical approach was developed by coupling an Epsom salt, E518 (magnesium sulfate)–facilitated salting-out assisted liquid–liquid extraction (SALLE) system with a safe molecular...

Abstract Nitrous oxide (N2O) is a strong greenhouse gas that contributes significantly to global warming and causes depletion of ozone in the stratosphere. Recent observational records show an unprecedented acceleration ...

Along with the increasing requirement for efficient organic conversions using green chemistry, there is a need to develop highly efficient and eco-friendly catalytic reaction systems. Gold nanoparticles (AuNPs)-based nan...

The pecan nutshell [Carya illinoinensis (Wangenh) C. Koch] (PNS) is a source of bioactives with important beneficial properties for the human health. PNS represents between 40–50 % of total mass of the nut, resulting ...

Anions are ionic species that play important roles in biology, medicine, catalysis, and environmental science. Identifying these species is crucial for industrial applications and clinical diagnostics. In recent years, e...
