“…The rutile structure of stoichiometric RuO 2 (110) [11] consists of a slightly distorted octahedron with 4 equatorial and 2 apical Ru-O directions. On the surface, bridging oxygen atoms are coordinated with two Ru atoms underneath, and a Ru atom on a onefold coordinatively unsaturated site is coordinated with five oxygen atoms [12].…”

By cyclic voltammetry at high scan rates, the electrochemical properties of RuO 2 in acidic and alkaline solutions were investigated in detail. Thirteen current peaks can be distinguished in sulfuric acid and sodium hydroxide. With respect to the pH sensitivity of RuO 2 electrodes, we considered charge calculations, peak currents, and apparent diffusion coefficients. The nature of the Ru(II) oxidation was clarified by Ru(I)−Ru(III) species.

“…Therefore, the electrons calculated vary with the two methods. Equation (11) suggests three electrons for the Ru(V) → Ru(VIII) oxidation. This is confirmed by the peak potential method, but the calculated electrons from the charge propose a oneelectron transfer reaction Ru(VII) → Ru(VIII) [24,25].…”

Using scanning tunneling microscopy (STM) together with density functional theory (DFT) the growth behavior of perylene on the Cu(100) substrate has been investigated. As revealed by STM images, perylene molecules prefer to adopt lying configuration with their molecular plane parallel to the substrate, and two symmetrically equivalent ordered domains were observed. DFT calculations show that perylene molecule prefers to adsorb on the top site of substrate Cu atoms with its long molecular axis aligning along the [011] or [01-1] azimuth of the substrate which is the most stable adsorption geometry according to its highest binding energy. Consequently, two adsorption structures of c(8×4) and c(8×6), each containing two perylene molecules per unit cell, are proposed based on our STM images. The growth mechanism for ordered perylene domains on Cu(100) can be attributed to the balance between weak adsorbate-adsorbate interaction and comparable adsorbate-substrate interaction.
