Cyclohexanone oxime is formed from nitrobenzene with 97% yield
in a one-pot reaction catalysed by palladium and gold nanoparticles
on carbon. The reaction is carried out under hydrogen at
60 8C and the overall transformation ...

The photooxygenation of model compounds containing the two enantiomers of naproxen (NPX) covalently
linked to histidine (His), tryptophan (Trp) and tyrosine (Tyr) has been investigated by steady state
irradiation, ...
[EN] The aim of this study was to assess the effect of light, oxygen and microalgae on micropollutants removal. The studied micropollutants were 4-(1,1,3,3-tetramethylbutyl)phenol (OP), technical-nonylphenol (t-NP), ...
