  1. Porous poly(bismaleimide‐co‐divinylbenzene) microspheres as dispersive solid‐phase extraction adsorbent coupled to high‐performance liquid chromatography for the determination of triazine herbicide residues in vegetable samples

    • Journal of Separation Science
    • In this work, monodisperse and nano‐porous poly(bismaleimide‐co‐divinylbenzene) microspheres with large specific surface area (427.6 m2/g) and rich pore structure were prepared by one‐pot self‐stable precipitation polymerization of 2,2′‐bis[4‐(4‐maleimidophenoxy) phenyl] propane and divinylbenzene. The prepared poly(bismaleimide‐co‐divinylbenzene) microspheres were employed as dispersive solid‐phase extraction (DSPE) adsorbent for the extraction of triazine herbicides.

  13. Development and validation of a random forest algorithm for source attribution of animal and human Salmonella Typhimurium and monophasic variants of S. Typhimurium isolates in England and Wales utilising whole genome sequencing data

    • Frontiers in Microbiology
    • Source attribution has traditionally involved combining epidemiological data with different pathogen characterisation methods, including 7-gene multi locus sequence typing (MLST) or serotyping, however, these approaches have limited resolution. In contrast, whole genome sequencing data provide an overview of the whole genome that can be used by attribution algorithms. Here, we applied a random forest (RF) algorithm to predict the primary sources of human clinical Salmonella Typhimurium (S.
