Green synthesis of gold nanoparticles using the seaweed Fucus spiralis and thei...

The increasing prevalence of neurodegenerative diseases such as Alzheimer's disease (AD) underscores the need for effective therapeutic strategies. Nanotechnology can provide new tools to counteract neurotoxicity, namely by improving bioavailability of therapeutic molecules in the brain. Brown seaweeds, such as Fucus spiralis (FS), are rich in bioactive compounds with antioxidant, anti-inflammatory, cytoprotect...

Hidden dangers of synthetic cathinones: unveiling the role of oxidative stress ...

Background: Synthetic cathinones (SCs) are the second most reported class of new psychoactive substances worldwide, according to the United Nations Office on Drugs and Crime (UNODC), with over 100 analogues identified [1]. These recreational stimulants exhibit pharmacological properties similar to amphetamines [2] and have been associated with serious cardiac events, including myocardial infarction and sudden c...

Algae-powered innovation: A critical review of sustainable textile dyeing and f...

The textile industry is under increasing scrutiny for its environmental impact, standing out as one of the largest contributors to pollution. In response, pursuing sustainable production practices, through the adoption of eco-friendly materials and sustainable processes, is essential for shaping a more sustainable future. Marine algae have emerged as promising natural alternatives for textile dyeing and functio...

Environmental remediation promoted by silver nanoparticles biosynthesized by eu...

A simple and low-cost green synthesis method was optimized to prepare stable silver nanoparticles (AgNP) using aqueous Eucalyptus globulus leaves extract. This green method allows to obtain AgNP with spherical morphology and variable size around 25 nm, and it is dependent of the reaction temperature and concentration of the plant extract. AgNP stability was followed during 3 months by zeta potential measurement...

Rehabilitation of a complex industrial wastewater containing heavy metals and o...

This work addresses the treatment of a complex industrial effluent containing high concentrations of metals and spiked with two organic solvents (diethylketone DEK, and methyl ethyl ketone - MEK) using an eco-friendly approach. The treatment system herein proposed consists of a bio-barrier that combines the adsorption capacity of sepiolite with the properties of a Streptococcus equisimilis biofilm with proven a...

Chapter 14 - Retention of organic micro-pollutants by sorption processes

This chapter is a review of the impacts of organic micro-pollutants on the environment and quality of life in general, and of the sorption processes that these molecules go through when released into water, air, or soils. Potential sorbents for these compounds are listed and discussed, with particular focus on low-cost green sorbents, that otherwise would constitute another waste to be treated. The economic and...

Waste-based biosorbents as cost-effective alternatives to commercial adsorbents...

The goal of this study is to demonstrate that waste-based biosorbents can be cost-effective and green alternatives to commercial adsorbents for the retention of pharmaceuticals. Adsorption kinetics and equilibrium measurements allowed the determination of the adsorption capacity of commercial adsorbents (GAC - granular activated carbon and two synthetic zeolites) and waste-based biosorbents (SCG - spent coffee ...

A review on biological processes for pharmaceuticals wastes abatement: a growin...

Over the last decades, the production and consumption of pharmaceuticals and health care products grew manifold, allowing an increase in life expectancy and a better life quality for humans and animals, in general. However, the growth in pharmaceuticals production and consumption comes with an increase in waste production, which creates a number of challenges as well as opportunities for the waste management in...

Rehabilitation of water contaminated with an organic solvent by an aerobic bact...

Valorization of spent coffee grounds as biosorbent for the retention of fluoxet...

The goal of this study is to evaluate and to compare the effectiveness of spent coffee grounds (SCG), a waste-based biosorbent, and granular activated carbon (GAC) for the removal of fluoxetine, a widely consumed psychiatric pharmaceutical. Equilibrium measurements performed in batch experiments allowed to determine the adsorption capacity of the materials under evaluation. GAC had by far the highest adsorption...
