Retracted Article: Search for time variation of the fine-structure constant using [O III] emission lines This article has been published OnlineFirst, but is withdrawn due to following investigation of complaints received against it. In consultation with the author, both the author and the Editor in Chief Michael Dopita have agreed that substantial portions of the text came from other papers, most notably from Paolo Molaro et al. 2005, Proceedings IAU Symposium No. 232, without attribution, so this clearly constitutes plagiarism. It is clear that the author’s lack of experience in publishing scientific papers led him to make this error. However, whatever the cause, plagiarism in any form cannot be countenanced. The Editor in Chief also notes that the other authors of the paper were unaware of the issue of plagiarism, and that no blame attaches to them...

Graphene sheets synthesized by ionic-liquid-assisted electrolysis for application in water purification A facile and green synthesis of graphene sheets by ionic-liquid-assisted electrolysis was investigated in this work. The synthesized graphene sheets have been studied using transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray powder diffraction (XRD), Raman spectroscopy (Raman) and Fourier transform infrared (FTIR) analysis. The obtained graphene was used for the adsorption of Fe2+ whose presence in the drinking water in wide areas of South Asia has been widely known. The result shows that the graphene could absorb Fe2+ with a capacity of 299.3 mg/g which is 6 times higher than that of graphite oxide. The adsorption properties of metal ions on graphene and the effects of variou factors on the adsorption capacity were also investigated in detail. The research results suggest a novel material for developing highly efficient water purification mater...
