Comparison of intra- vs intermolecular long-range electron transfer in crystals of ruthenium-modified azurin

Article Abstract:

The impact of variable protein structure both intra- and intermolecular electron transfer (ET) is studied by developing methods for studying such reactions in single crystals, which fix the association modes of molecules in an environment that could be subjected to structural analysis by x-ray diffraction. Unlike ET between soluble factors, the three-dimensional crystal lattice generates multiple fixed spatial relationships for the same donor (D) and acceptor (A).

Origin of the enhanced catalytic activity of carbon nanocoil-supported PtRu alloy electrocatalysts

Article Abstract:

The detailed investigation done on the relationship between the electrocatalytic performance of PtRu catalysts and the characteristics of the carbon supports is presented. Catalysts supported on carbon materials with specific characteristics such as a highly graphitic structure showed improved catalytic activities as a result of a preferred crystallographic orientation by interactions with the highly ordered substrate.

Structure and electrocatalysis of sputtered RuPt thin-film electrodes

Article Abstract:

The structural and electrochemical properties of RuPt thin-films electrodes fabricated by radio frequency (rf) magnetron sputtering is investigated. Characterization of the film is carried out using grazing incidence X-ray diffraction and electrochemical measurements.
