Combined coulometric and voltammetric analytical approach provides novel insights into the antioxidant capacity of natural coumarins and furanocoumarins.

Despite intense investigation on the subject, the information available on the antioxidant capacity of natural coumarins and furanocoumarins is controversial. In the present study the antioxidant capacity of 19 pure naturally occurring compounds, among which 5 coumarins and 14 furanocoumarins is determined, using both the coulometrically determined antioxidant capacity (CDAC) and linear sweep voltammetry (LSV). None of the coumarins and furanocoumarins assayed exhibited appreciable scavenging activity against the DPPH radical.

New piperazine and morpholine derivatives: Mass spectrometry characterization and evaluation of their antimicrobial activity.

Recently, pharmaceutical research has been focused on the design of new antibacterial drugs with higher selectivity towards several strains. Major issues concern the possibility to obtain compounds with fewer side effects, at the same time effectively overcoming the problem of antimicrobial resistance. Several solutions include the synthesis of new pharmacophores starting from piperazine or morpholine core units.

Reduction of antimicrobial resistance: Advancements in nature-based wastewater treatment.

Water scarcity, affecting one-fifth of the global population, is exacerbated by industrial, agricultural, and population growth pressures on water resources. Wastewater, containing Contaminants of Emerging Concern (CECs) such as antibiotics, presents environmental and health hazards. This study explores a Nature-Based Solution (NBS) using Constructed Wetlands (CWs) for wastewater reclamation and CECs removal.

UV light assisted degradation of acid orange azo dye by ZVI-ZnS and effluent toxicity effects.

Azo dyes, the most common synthetic dyes used in the textile industry, are known xenobiotic compounds and recalcitrant to conventional degradation treatments. As consequence, such contaminants are often discharged into the effluents, treating aquatic ecosystems. Among several processes, the use of zero valent iron (ZVI) represents a suitable alternative to degrade organic molecules containing azo bonds.

A Green Bioactive By-Product Almond Skin Functional Extract for Developing Nutraceutical Formulations with Potential Antimetabolic Activity.

(1) Background: almond peels are rich in polyphenols such as catechin and epicatechin, which are important anti-free-radical agents, anti-inflammatory compounds, and capable of breaking down cholesterol plaques. This work aims to evaluate the biological and technological activity of a "green" dry aqueous extract from Sicilian almond peels, a waste product of the food industry, and to develop healthy nutraceuticals with natural ingredients. Eudraguard Natural is a natural coating polymer chosen to develop atomized formulations that improve the technological properties of the extract.
