A Mathematical Model of Flavescence Dorée Epidemiology [PDF]
arXiv, 2014 Flavescence dor\'ee (FD) is a disease of grapevine transmitted by an insect vector, $Scaphoideus$ $titanus$ Ball. At present, no prophylaxis exists, so mandatory control procedures (e.g. removal of infected plants, and insecticidal sprays to avoid transmission) are in place in Italy and other European countries.

A Thermostable Bacterial Metallohydrolase that Degrades Organophosphate Plasticizers
ChemBioChem, EarlyView.This bacterial enzyme, cyclase‐phosphotriesterase (C‐PTE) from Ruegeria pomeroyi DSS‐3, shows significant potential for breaking down organophosphate pollutants. Beyond its capability to hydrolyze specific plasticizers such as triphenyl phosphate and tris(2‐chloropropyl) phosphate, C‐PTE's crystal structure reveals a binuclear zinc active site, and it ...

Rethinking Chlorine: Essential Chemical or Replaceable Risk?
ChemSusChem, EarlyView.Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...
