Metal clusters laboratory experiments

Experiments were performed in the critical heavy-water facility ZED-2 located at AECL s Chalk River Laboratories to measure die buckling of a superlatUce. The lattice shown in Fig. 1 contained 4S 19-elemeht natural uranium metal clusters and 44 ZEEP rods in a square lattice. The 19-element U-metal clusters con-... 

The 3d transition metals are widely employed as catalyst and catalyst support materials in industry [3]. To gain insight into how these support materials and the catalyst support interaction influence catalytic activity, GIB-MS experiments were undertaken in our laboratory to determine the structural characteristics of cobalt oxide and nickel oxide clusters as well as their reactivity with CO. CID experiments were conducted employing Xe gas to elucidate the structural building blocks of the larger clusters. These studies provided insight into how additional (i-electrons impact the dissociation pathways and bonding motifs of 3d transition metal oxide clusters. Reactivity studies with CO were carried out, which revealed that oxide clusters composed of different 3d metals have specific stoichiometries which are most active for CO oxidation.
