Surface layer expansion due to proton insertion during reduction of RuO{sub 2}(100) single crystal electrodes.

Description: Ruthenium dioxide has received much interest due to its nearly ideal properties for use as the active material in ultracapacitors. Ultracapacitors,a new type of energy storage device, share similarities to both conventional capacitors in that energy is stored by separation of charge and to batteries where charge is stored in chemical reactions. The chemical charge storage mechanism is referred to as pseudo-capacitance, as the Faradaic charge is distributed relatively even across a large portion… more

Resonance X-ray scattering from Pt(111) surfaces under water

Description: The resonance X-ray scattering from the unmodified, clean Pt(111) surface is compared to theoretically predicted scattering. Self-consistent real-space multiple-scattering approach is used to calculate the real and imaginary parts of the atomic platinum scattering factor. The experimentally observed near-edge fine structures of the surface-scattering and fluorescence intensities are well reproduced by the calculations. In addition, more details are presented on their previous study [Phys.Rev.Le… more

Investigation of the structure of rhodium films electrodeposited on Au(111) single crystals.

Description: The structure of rhodium films electrodeposited on (111) surfaces of gold was investigated using cyclic voltammetry, x-ray scattering measurements and scanning tunneling microscopy (STM). A better understanding of the rhodium deposition process and film structure was gained. After mechanical polishing the Au(111) crystal was electropolished and annealed in an hydrogen flame. These crystal preparation procedures yielded a gold single crystal with electrochemical characteristics comparable to pre… more
