A new method for the synthesis of formamides has been developed by the N-formylation of amines with formic acid in the presence of nano cerium oxide as an efficient and recyclable catalyst under ultrasound irradiation. The reaction system is remarkably simple and environmentally benign.
N-[(Diphenylamino)methyl]acetamide was synthesized using Mannich reaction and its complexes of cerium(IV), thorium(IV) and dioxouranium(VI) were prepared and characterized by elemental analysis and various spectral studies. The bidendate chelation of ligand, bonding through carbonyl oxygen and azomethine nitrogen is suggested. Based on spectral and magnetic studies, hexa coordinate geometry is ...
Interest in engineered nanostructures has risen in recent years due to their use in energy conservation strategies and biomedicine. To ensure prudent development and use of nanomaterials, the fate and effects of such engineered structures on the environment should be understood. Interactions of nanomaterials with environmental microorganisms are inevitable, but the general consequences of such ...
Objective- The healing effect of chitosan supported cerium oxide nanoparticles (nano-CeO2) on cutaneous experimental excisional wound infected with pseudomonas aeruginosa was studied in rat. Design- Experimental Study. Animals- Sixty male albino rats. Procedures- The chitosan supported nano-CeO2 hydrogel was prepared and characterized using Fourier-transform infrared spectro...
