Institute of Green Chemistry and Chemical Technology, Advanced Chemical Engineering Laboratory of Green Materials and Energy of Jiangsu Province, School of Chemistry and Chemical Engineering, Jiangsu University, Zhenjiang 212013, China. Electronic address:

Introducing membrane filtration into advanced oxidation processes to decrease energy and cost consumption has been considered as a promising direction in environmental remediation. In this work, we firstly developed a kind of novel lawn-like FeO@CoFe@nitrogen-doped reduced graphene oxide@carbon nanotube composites (FeCo@GCTs) through in-situ pyrolysis of self-assembly of Prussian blue analogues and GO, followed through a vacuum-assisted filtration strategy to fabricate 2D confinement freestanding GO composite membrane. Electrochemical analysis and H-TPR revealed the superiority of FeCo@GCTs as ideal electron acceptor, and this unique lawn-like structure concentrated active sites with a confined space and enriched oxygen vacancies that realized 98.

Poorer diversity but tougher species in old ballast water: Biosecurity challenges explored from visual and molecular techniques.

Mar Pollut Bull 2021 May 12;168:112465. Epub 2021 May 12.

Department of Functional Biology, University of Oviedo, C/ Julian Claveria s/n, 33006 Oviedo, Spain.

Millions of tons of water cross the oceans inside ships' ballast tanks every day. Planktonic species hitch-hike with water and some may pose risks to ecosystems and economies if get released and establish outside their native range. We monitored ballast water in different trans-equatorial travels, visually and using molecular techniques, and found significant increases of potential nuisance taxa over travel duration, despite evident diversity depletion.

GEMMA-Group of Environmental Engineering and Microbiology, Department of Civil and Environmental Engineering, Universitat Politècnica de Catalunya-BarcelonaTech, c/ Jordi Girona 1-3, Building D1, E-08034 Barcelona, Spain. Electronic address:

One of the key features of nature-based solutions (NBSs) is their high effectiveness and economic and resource efficiency in solving problems compared to traditional grey interventions. These aspects, however, have so far attracted little attention in the literature but should be considered, as the evaluation of NBS projects before implementation provides an opportunity to use them as practical tools. This paper aims to present a new evaluation framework of NBS projects (at the stage of solution selection) based on the application of performance questions and the indicators approach. Read More

Sci Total Environ 2021 May 8;787:147606. Epub 2021 May 8.

School of Environmental Engineering, Technical University of Crete, 73100 Chania, Greece.

The effect of copper (Cu-NPs, CuO-NPs), silver (Ag-NPs) and zinc oxide (ZnO-NPs) nanoparticles (NPs) on plant growth, physiological properties of tomato plants and their symbiotic relationships with the endophytic Fusarium solani FsK strain was investigated. Fungitoxicity tests revealed that the FsK strain was significantly more sensitive to Cu-NPs and ZnO-NPs than CuO-NPs and Ag-NPs both in terms of mycelial growth and spore germination. All NPs were more toxic to FsK compared to their bulk counterparts except for AgNO, which was 8 to 9-fold more toxic than Ag-NPs. Read More

Rescue of striatal long-term depression by chronic mGlu5 receptor negative allosteric modulation in distinct dystonia models.

Neuropharmacology 2021 May 12:108608. Epub 2021 May 12.

Department of Brain and Behavioral Sciences, University of Pavia, Italy; IRCCS Mondino Foundation, Pavia, Italy. Electronic address:

An impairment of long-term synaptic plasticity is considered as a peculiar endophenotype of distinct forms of dystonia, a common, disabling movement disorder. Among the few therapeutic options, broad-spectrum antimuscarinic drugs are utilized, aimed at counteracting abnormal striatal acetylcholine-mediated transmission, which plays a crucial role in dystonia pathophysiology. We previously demonstrated a complete loss of long-term synaptic depression (LTD) at corticostriatal synapses in rodent models of two distinct forms of isolated dystonia, resulting from mutations in the TOR1A (DYT1), and GNAL (DYT25) genes.
