Using the results of molecular dynamics (MD) simulations, we discuss the question of whether the observed difference in mass limits in secondary ion mass spectrometry (SIMS) and matrix assisted laser desorption ionization (MALDI) are inherently related to the underlying physics of ejection or rather insuf®cient experimentation. The simulations show clearly(More)
Molecular dynamics simulations have been used to model the kiloelectronvolt particle bombardment of organic layers on metal substrates such as occurs in the analytical techniques of secondary ion mass spectrometry and fast atom bombardment mass spectrometry. Vignettes of insights gained from the simulations along with comparisons to experimental data are(More)
Heterometal clusters containing Ru and Au, Co and/or Pt are anchored onto carbon nanotubes and nanofibers functionalized with chelating phosphine groups. The cluster anchoring yield is related to the amount of phosphine groups available on the nanocarbon surface. The ligands of the anchored molecular species are then removed by gentle thermal treatment in(More)
