X-ray Raman scattering study of aligned polyfluorene [PDF]

, 2006
We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption ...

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.

Effect of electrokinetic on biodegradation of fluorene and phenanthrene in soil [PDF]

Iranian Journal of Chemical Engineering, 2016
Polycyclic aromatic hydrocarbons (PAH) are toxic, mutagenic, and carcinogenic compounds. Removal of these compounds has a great importance for environment. Removal of PAHs from soil is difficult as these chemicals are persistent in the soil.
