Complexes Of Transition Metals

Complexes of transition metals with chiral ligands are considered as catalysts. Among metal-containing organic complexes with semiconducting properties, compounds of the porphin series occupy a special place in electrocatalytic studies. The properties of the porphyrin macrocycle, their role in catalysis, and the influence of the nature of the metal on the catalytic properties of the complex are considered.

Dextran aldehyde (dexOx), resulting from the periodate oxidative cleavage of 1,2-diol moiety inside dextran, is a polymer that is very useful in many areas, including as a macromolecular carrier for drug delivery and other biomedical applications. In particular, it has been widely used for chemical engineering of enzymes, with the aim of designing better biocatalysts that possess improved catalytic properties, making them more stable and/or active for different catalytic reactions. This polymer possesses a very flexible hydrophilic structure, which becomes inert after chemical reduction; therefore, dexOx comes to be highly versatile in a biocatalyst design. This paper presents an overview of the multiple applications of dexOx in applied biocatalysis, e.g., to modulate the adsorption of biomolecules on carrier surfaces in affinity chromatography and biosensors design, to serve as a spacer arm between a ligand and the support in biomacromolecule immobilization procedures or to generate artificial microenvironments around the enzyme molecules or to stabilize multimeric enzymes by intersubunit crosslinking, among many other applications.

The d-band centre comes back from the dead being the most consistent of the main electronic descriptors, due to its excellent transferability between five density functionals. The robustness previously observed for bulk is here evaluated for transition metal surfaces and if large surface states are not involved, a direct relation with the coordination number is disclosed.
