Synthesis and antifungal activities of some aryl (3-methyl-benzofuran-2-yl) ketoximes

In this study, some aryl (3-methyl-benzofuran-2-yl) ketoximes and their. ethers and esters were synthesised. The structure elucidation of the compounds was performed by IR, H-1-NMR, MASS spectroscopy and elemental analyses. Antifungal activities of the compounds were examined and moderate activity was obtained

Reduced graphene oxide-based hydrogels for the efficient capture of dye pollutants from aqueous solutions

Three dimensional (3D) reduced graphene oxide (RGO)-based hydrogels were synthesized by the reduction of graphene oxide using sodium ascorbate. During gelation, mono-, bi-, and trilayer graphene nanosheets self-assemble into a well-defined and interconnected 3D porous network through strong van der Waals and pi-pi interactions. The 3D RGO-based hydrogels showed a large surface area, and a uniform pore size distribution. The application of the 3D mesoporous material as an adsorbent for the removal of the organic dyes, methylene blue (MB) and rhodamine B (RhB), from aqueous solutions was investigated. The 3D RGO-based hydrogels showed excellent removal capabilities for MB (similar to 100%) and RhB (similar to 97%) due to adsorption through strong pi-pi stacking and anion-cation interactions. Toxicity tests show that the aqueous solutions purified by 3D RGO-based hydrogels are comparable to control experiments conducted using distilled water.close362
