New polymeric films with antibacterial activity have been prepared, by simple UV-induced copolymerization of readily available Ï-(acryloyloxy)-N,N,N-triethylalcan-1-aminium bromides (or acryloyloxyalkyltriethylammonium bromides, AATEABs) with commercially available 2-hydroxyethyl methacrylate (HEMA), at different relative amounts. In particular, the antibacterial activity of polymeric films derived from 11-(acryloyloxy)-N,N,N-triethylundecan-1-aminium bromide (or acryloyloxyundecyltriethylammonium bromide, AUTEAB; bearing a C-11 alkyl chain linker between the acrylate polymerization function and the quaternary ammonium moiety) and 12-(acryloyloxy)-N,N,N-triethyldodecan-1-aminium bromide (or acryloyloxydodecyltriethylammonium bromide, ADTEB, bearing a C-12 alkyl chain linker) has been assessed against Gram-negative Escherichia Coli and Gram-positive Staphylococcus aureus cells. The results obtained have shown a clear concentration-dependent activity against both bacterial strains, the films obtained from homopolymerization of pure AUTEAB and ADTEAB being the most effective. Moreover, ADTEAB-based films showed a higher antibacterial activity with respect to the AUTEAB-based ones. Interestingly, however, both types of films presented a significant activity not only toward Gram-positive S. aureus, but also toward Gram-negative E. Coli cells. |

Synthesis and Antibacterial Activity of Polymerizable Acryloyloxyalkyltriethyl Ammonium Salts |

AbstractThis study reports an efficient and practical synthetic approach for the synthesis of a particularly important class of polymerizable quaternary ammonium salts (PQASs), that is, acryloxyalkyltriethylammonium bromides (AATEABs), which may find application as antimicrobial coatings for commercial membranes with antifouling and antiâbiofouling properties, to be used for wastewater treatment. The synthetic method is based on a simple twoâstep procedure from commercially available substrates, entirely carried out under air and without any need for chromatographic purification. All the newly synthesized AATEABs were tested for their antimicrobial activity, and the results showed that AATEABs bearing an alkyl chain of 11 and particularly 12â
carbon atoms possessed significant activity against Gram positive bacteria and yeast strains. |

Spatial and temporal analysis of extreme sea level and storm surge events around the coastline of the UK |

AbstractIn this paper we analyse the spatial footprint and temporal clustering of extreme sea level and skew surge events around the UK coast over the last 100 years (1915â2014). The vast majority of the extreme sea level events are generated by moderate, rather than extreme skew surges, combined with spring astronomical high tides. We distinguish four broad categories of spatial footprints of events and the distinct storm tracks that generated them. There have been rare events when extreme levels have occurred along two unconnected coastal regions during the same storm. The events that occur in closest succession (<4 days) typically impact different stretches of coastline. The spring/neap tidal cycle prevents successive extreme sea level events from happening within 4â8 days. Finally, the 2013/14 season was highly unusual in the context of the last 100 years from an extreme sea level perspective. |

Algae Drive Enhanced Darkening of Bare Ice on the Greenland Ice Sheet |

AbstractSurface ablation of the Greenland ice sheet is amplified by surface darkening caused by lightâabsorbing impurities such as mineral dust, black carbon, and pigmented microbial cells. We present the first quantitative assessment of the microbial contribution to the ice sheet surface darkening, based on field measurements of surface reflectance and concentrations of lightâabsorbing impurities, including pigmented algae, during the 2014 melt season in the southwestern part of the ice sheet. The impact of algae on bare ice darkening in the study area was greater than that of nonalgal impurities and yielded a net albedo reduction of 0.038 ± 0.0035 for each algal population doubling. We argue that algal growth is a crucial control of bare ice darkening, and incorporating the algal darkening effect will improve mass balance and sea level projections of the Greenland ice sheet and ice masses elsewhere. |
