Reply to "comment an 'interaction of hydrogen with RuO2(110) surfaces: Activity differences between various oxygen species '"

Article Abstract:

A comment on the results of the interaction of hydrogen with RuO2(110) surfaces, which could be prepared in the stoichiometric state by annealing at 700 K within O2 at a pressure of 1 x [10.sup.-7] mbar and in a more oxygen-rich state by further exposing the surface to O2 at 300 K, is presented. The conclusion that the more strongly bonded O-bridge is more reactive against hydrogen than the less strongly bonded O-cus, is contradicting experimental results, chemical intuition, and theoretical ab-initio calculations.

Fabrication of interconnected 1D molecular lines along and across the Dimer rows on the Si(100)-(2 x 1)-H surface through the radical chain reaction

Article Abstract:

The fabrication of interconnected one-dimensional (1D) molecular lines through the radical chain reaction of alkene molecules (CH(Sub 2)=CH-R) on the H-terminated Si(100)-(2 x 1) surface are investigated using scanning tunneling microscopy (STM) at 300 K for realizing nanoscale wiring in two dimensions (2D). The electronic properties of 1D molecular lines along the dimer rows on the Si(100)-(2 x 1)-H surface opens a new possibility of using such a 1D molecular line as a connecting wire.

Initial growth of the water layer on (1 x 1)-oxygen-covered Ru(0001) in comparison with that on bare Ru(0001)

Article Abstract:

Temperature-programmed desorption (TPD) and infrared reflection absorption spectroscopy (IRAS) are used to study the initial growth of a water (D2O) layer on (1 x 1)-oxygen-covered Ru(0001) in comparison with that on bare Ru(0001). The TPD and IRAS measurements for the two surfaces exhibit distinct differences even though water molecules absorbed on both bare and (1 x 1)-oxygen-covered Ru(0001) commonly tend to form hydrogen bonds with each other when mobility occurs on heating.
