Data on adsorption were analyzed using linear and non-linear forms of first-

and second-order kinetic equations and also Langmuir and Freundlich isotherm models and results showed that maximum adsorption amounts of 90.9 mg g(-1) and 158.7 mg g(-1), were obtained for 2MBO and 2MBT, respectively.

CONCLUSION: The proposed removal method is independent of pH level of the sample solution and is effective over a wide range of pH values. Using a copper oxide nanoparticle loaded cartridge (CONLC) has the advantage that there is no need to collect nanoparticles after the removal process and that CONLC can be reused for further removal processes (at least three times). This method was successfully applied to remove 2MBT (>= 95% removal) from the cooling water of a 3000 learn more MW power plant. (C) 2013 Society of Chemical Industry”
“Different dodecanethiol capped Au nanoparticles (NP) with similar

sizes (similar to 2 nm) but different ferromagnetic signals at room temperature have been investigated by means of x-ray absorption spectroscopy at the Au L-3-edge. The reversion of the x-ray magnetic circular dichroism signal with the change of sign of the external applied magnetic field confirms the location of the magnetism at the Au atoms. In comparison with the Au foil, all the samples present accentuated white lines at the x-ray absorption near-edge structure (XANES) indicating generation DMH1 molecular weight of 5d holes in the Au atoms located at surface of the NPs as consequence of a localized charge transfer from the Au surface

atoms to the S atoms of the capping agent. XANES spectra reflect differences among the electronic structure of the Au NPs which are compared with the observed different macroscopic magnetic signals. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3059609]“
“Occasional clinical reports have suggested a link between migraine and restless legs syndrome. We undertook a systematic review of the evidence, which supports this association, and consider selleck kinase inhibitor possible shared pathogenic mechanisms and the implications for current clinical practice.”
“BACKGROUNDPretreatment methods used to break down lignocellulose structure lead to the generation of compounds that inhibit ethanol fermentation. Hence, removal of these compounds is essential for improved fermentability. The surfactant-based cloud point extraction (CPE) aqueous two phase system is a new method having the potential for separation and recovery of inhibitors. The present work examines the potential of surfactants-based CPE systems as a detoxification method.
