Abstract

Water bodies contamination is a pressing issue of modern society, exacerbated by the large structural variety of contaminants. This explains the interest toward developing systems able to remove from wastewater different contaminants, with different susceptibility to removal methods. Consequently, herein hybrid ionic liquid gels, based on 1,3:2,4‐dibenzylidene‐D‐sorbitol (DBS), doped with graphite, carbon nanotubes, graphene, and graphene oxide, are described. First, the gel–sol transition temperatures (Tgel), rheological and self‐healing properties are determined. These gels are then used as sorbent materials and, for the first time, for removing mixtures of pollutants of different classes, namely the dyes rhodamine B and methyl orange, the drugs diclofenac and carbamazepine, or the endocrine disruptor bisphenol A, to simulate real wastewaters. Interestingly, hybrid gels prove efficient in removing single and mixed pollutants. The best performing gel is reusable for at least 12 consecutive cycles, without any intermediate washing. It can also be embedded in adsorption columns or dialysis membranes, to treat larger volumes of wastewater. Here, this gel achieves an adsorption capacity of 117 and 66 mg g−1 for rhodamine B and bisphenol A in mixture, with a distinct preference toward cationic contaminants, exhibiting competitive performance with most systems previously reported.

Abstract

With the aim to obtain targeted chemotherapeutic agents, imidazolium and ammonium-based folate salts were synthesized. Their photophysical behavior was investigated both in buffer and buffer/DMSO solution as well as in solid phase, performing UV-vis and fluorescence investigations. Properties of the aggregates were also analyzed by dynamic light scattering. Gelation ability of the salts was analyzed in biocompatible solvents, and gel phases obtained were characterized by determining critical gelation concentrations and gel-solution transition temperatures. Insights about gelator interactions in the tridimensional network were also gained performing ATR-FTIR investigation. Properties of soft materials were further analyzed performing rheology measurements, scanning electron microscopy, fluorescence and resonance light scattering investigations. Antiproliferative activity of organic salts was tested towards two breast cancer cell lines, expressing different levels of folate receptor, namely MDA-MB-231 and MCF-7, and a normal epithelial cell line, like h-TER T-RPE-1, by using MTT assay. Dichlodihydrofluorescein acetate test was performed to verify the role of oxidative stress in cell death. Finally, antiproliferative activity was also evaluated in gel phase, to verify if salts were able to retain biological activity also after the entrapment in the gelatinous network. Results collected evidence that folate based organic salts were able to behave as targeted chemotherapeutic agents both in solution and gel phase, showing uptake mechanism and selectivity indexes that depend on both cancer cell line nature and salt structure.

Abstract

If climate services are to lead to effective use of climate information in decision-making to enable the transition to a climate-smart, climate-ready world, then the question of trust in the products and services is of paramount importance. The Copernicus Climate Change Service (C3S) has been actively grappling with how to build such trust: provision of demonstrably independent assessments of the quality of products, which was deemed an important element in such trust-building processes. C3S provides access to essential climate variables (ECVs) from multiple sources to a broad set of users ranging from scientists to private companies and decision-makers. Here we outline the approach ­undertaken to coherently assess the quality of a suite of observation- and reanalysis-based ECV products covering the atmosphere, ocean, land, and cryosphere. The assessment is based on four pillars: basic data checks, maturity of the datasets, fitness for purpose (scientific use cases and climate studies), and guidance to users. It is undertaken independently by scientific experts and presented alongside the datasets in a fully traceable, replicable, and transparent manner. The methodology deployed is detailed, and example assessments are given. These independent scientific quality assessments are intended to guide users to ensure they use tools and datasets that are fit for purpose to answer their specific needs rather than simply use the first product they alight on. This is the first such effort to develop and apply an assessment framework consistently to all ECVs. Lessons learned and future perspectives are outlined to potentially improve future assessment activities and thus climate services.
