Fenton coupled with nanofiltration for elimination of Bisphenol A [PDF]

open access: yes, 2014
Bisphenol A (BPA) is a typical Endocrine Disrupting Chemical (EDC), which is potentially harmful during wastewater reclamation. In this study, its degradation during Fenton's process under different operational conditions was investigated in combination ...

Evidence linking exposure of fish primary macrophages to antibiotics activates the NF-kB pathway. [PDF]

open access: yes, 2020
Low doses of antibiotics are ubiquitous in the marine environment and may exert negative effects on non-target aquatic organisms. Using primary macrophages of common carp, we investigated the mechanisms of action following exposure to several common ...

A TGA/FTIR and Mass Spectral Study on the Thermal Degradation of Bisphenol A Polycarbonate [PDF]

open access: yes, 2004
The thermal degradation of polycarbonate under nitrogen was studied using TGA/FTIR, GC/MS and LC/MS as a function of mass loss. The gases evolved during degradation were inspected by in situ FTIR and then the evolved products were collected and analysed ...

Pivalolactone, 2. Copolyester synthesis via interchange reactions with polypivalolactone [PDF]

open access: yes, 1993
The synthesis of copolyesters via interchange reactions of polypivalolactone (PPVL) with several compounds was studied. The synthetical procedures are two-stage melt processes: in the first stage ester bonds in the polymer chain are cleaved and new ...
