  • The catalyst was characterized by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectrum. (hindawi.com)
  • The obtained samples were studied with analytical techniques such as X-ray powder diffraction (XRPD) and field emission scanning electron microscopy (FESEM). (mdpi.com)

  • Primarily, transition metals form complexes and their most observable property is their vivid color . (jrank.org)
  • In addition, many synthetic dyes and pigments are transition metal complexes, such as Prussian blue. (jrank.org)
  • The nanostructured layer can be formed using precursor sol, which generally includes one or more covalent metal complexes, one or more surfactants, a solvent, one or more optional condensation inhibitors, and (optionally) water. (google.es)
  • covalently crosslinking the surfactant-templated film to form a layer of porous material, wherein the film is based on the one or more covalent metal complexes of titanium, the nanostructured porous layer having pores with diameters between about 20 nm and about 50 nm with adjacent pores spaced between about 10 nm and about 50 nm.

  • pairs
  • In order to achieve aromaticity, the compound must be planar and possess an odd number of electron pairs in its pi system (the electrons that can participate in pi bonding). (csbsju.edu)
  • organometallic
  • Beta-elimination - in organometallic chemistry, a reaction analogous to 1,2-elimination in organic chemistry, but in which a metal center attached to the alkyl chain undergoing elimination is analogous to both the base and the leaving group in an organic 1,2-elimination. (csbsju.edu)
  • The octet rule is a rule of thumb that is only really applicable when dealing with the lighter elements (if one ever takes a class on organometallic chemistry, prepare yourself for the 18-electron rule - and of course all of its exceptions). (physicsforums.com)
  • holes
  • Depending on the mutual orientation of the spins of electrons (blue arrows) and holes (red arrows) on the Fermi surface, the system is either an ordinary half-metal (c) or a spin-valley half-metal (d). (mipt.ru)
