    Notes: Abstract The electroantennogram responses of synthetic (−)-periplanone-B (PB) and (−)-periplanone-A (PA) were evaluated by using the antennae of the unmated male American cockroachPeriplaneta americana L. The threshold concentrations of the pheromone activities for the two chemicals were similar. Neither a synergistic nor an inhibitory response was noted, and only an additive effect was detected when PA and PB were applied as a mixture.

    Melting of carbon cages (1993)

    Notes: Abstract We simulate the melting of carbon fullerenes by molecular dynamics using an accurate tight-binding model. The melting temperatures are obtained for fullerness ranging from C20 to C84. For small cages (n≤58), We found that the melting temperature increases almost linearly with the cluster size. However, the melting temperature of the larger fullerenes (n=60 and n≥70) is fairly constant and does not change much with cluster size.

    Photoabsorption spectra ofs 1-electron metal clusters (1991)
    Springer

    Notes: Abstract Collinear laser/molecular beam photodepletion spectroscopy has developed into a powerful tool for the determination of electronic absorption in neutral alkali metal clusters free of perturbing matrix effects. We briefly discuss the method, present data on selected Na x and Li y Na x−y ,x≤20, contrast measurements with the known optical response of larger colloidal metal clusters, compare microcluster spectra with the predictions of various models and speculate on future experimental and theoretical developments in this field.
