    Notes: Abstract To investigate whether cold fusion of deuterium (D) can occur in solid Pd and Ti as proposed recently, we have searched for the D-D fusion reaction in plasma-charged Pd-D and Ti-D. In a small reaction cell, a DC glow-discharge was established in a deuterium gas between two electrodes, with a Pd or Ti sample placed on the cathode. A thin (50 Å) Cu film was evaporated on the surface of the Pd samples to establish a barrier reducing the escape of D from the samples. Neutrons were detected with a liquid scintillator, and conventional pulse-shape discrimination technique was employed to distinguish gamma counts from neutron counts. No indication for a neutron count rate in excess of the natural background level was observed.

    Notes: Abstract This report describes a combined experimental and theoretical approach to the problem of designing surface alloys with specific chemical properties. Au-Ni(111) surface alloys were prepared and the distribution of active sites was determined by atomically resolved STM as a function of Au coverage. Using density functional theory the difference in activation energy for methane over the various sites was determined. The activity of the surface could be predicted directly by combining this information with the distribution of sites. Subsequent measurements of the activity proved this method to be quantitative and demonstrated that surface alloys with specific activity can be synthesized.
