Moreover, since the discovery of cis-platin and continuous research producing new generations of antitumour drugs, multidentate organic compounds containing metal ions, which are analogues in the catalyst of some metal enzymes, [14] have drawn the attention of researchers seeking novel, less toxic, less expensive and more efficient anti-cancer drugs.
Diagnosis: With simple multidentate hooked hooks and capillaries and yellow aciculae.
Key statement: The present invention is directed to a rubber composition comprising: a functionalized elastomer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and a functional group bonded to the backbone chain, the functional group comprising a multidentate ligand capable of complexing with a metal ion; and a metal ion.
MacroacyclicSchiff-base complexes based on transition metals and multidentate ligands are an interesting chemical field and have been the subject of extensive research due to their potential applications in fields of magnetochemistry, material science, catalysis, separation and ncapsulation processes, hydrometallurgy, formation of compounds with unusual properties and metalmetal interactions [8-25].
3+] and HA was studied using FTIR spectroscopy to identify the functional groups involved in complex formation, possible multidentate character of the ligands, and the effects of pH as well as addition of increasing amounts of Cr(III) on the IR bands associated with carbonyl symmetric and asymmetric stretching.
iv) Deprotonated multidentate organic acids are known to form complexes with transition metals (Violante and Gianfreda 2000) and also silicic acid (Marley et al.
Since it is reduced at more positive potentials and has no multidentate ligands which cause resistance against reduction process, it is much easier to reduce and it has a higher Cd (II) content in the final coverage.
We increased the hybridization temperature to destabilize the hybridization between a single CE and a surface capture probe while not affecting the stability of the multidentate interaction between the surface and multiple CEs.
Also, because of the multidentate nature of humic substances, it can be expected that the folding of the macromolecules (much like proteins) can bring various functional groups into the proximity of each other and, thereby, create binding sites that may significantly change the mechanism and strength of the metal cation speciation to humic substances.
