    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 The possibility of studying the texture of catalysts at the atomic level by Scanning Tunneling Microscopy (STM) is demonstrated. It is shown that high resolution pictures can be obtained even for a passivated ammonia synthesis catalyst using a scanning tunneling microscope operating in air. The STM results reveal that the catalyst has a spongy pore structure with both hole and slit shaped pores. The catalyst surfaces are observed to contain fine quite regular ridge structures with a direction that tentatively is related to the (110) direction of iron. The presence of the ridge structures is apparently the result of the topotactic nature of the reduction process and a preference to expose (111) Fe facets.
