The biocompatible surface modification of metal oxide nanoparticles via surface functionalization technique has been used as an important tool in nanotechnology and medicine. In this report, we have prepared aqueous dispersible, trivalent metal ion (samarium)-doped cerium oxide nanoparticles (SmCNPs) as model redox altered CNPs of biological relevance. SmCNP surface modified with hydrophilic bi...

The mixed-metal rare-earth polyphosphate LiSm(PO(3))(4) consists of a three-dimensional framework in which zigzag [(PO(3))(n)](n-) chains with a periodicity of four PO(4) tetrahedra are connected through Li(+) and Sm(3+) ions (both with 2. symmetry).

Limits are imposed upon the possible rate of change of extra spatial dimensions in Kaluza-Klein and superstring theories by considering the consequences of such changes for primordial nucleosynthesis and the positioning of nuclear resonance levels in samarium, carbon, and oxygen. Previous limits from nucleosynthesis had not included strong-interaction effects. The strongest limits constrain the...

To answer the question “How does lanthanide doping in iron oxide affect cure kinetics of epoxy-based nanocomposites?”, we synthesized samarium (Sm)-doped Fe3O4 nanoparticles electrochemically and characterized it using Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive X-Ray analysis (EDX), tran...

Cyclic hydrazones are efficient ketyl radical acceptors in reductive coupling cyclizations mediated by samarium diiodide, affording cyclic amino alcohols with controlled stereochemistry at the new aminated stereocenter. This approach has been successfully applied to the stereoselective synthesis of a fully functionalized trehazolin cyclitol starting from D-glucose, where the required cyclic hyd...
