Neutralization and matrix deposition experiments on mass-selected silver atoms and clusters Metal cluster cations, produced by Ar. sputtering, may be energy analyzed and then mass selected in a quadrupole mass filter. The clusters are neutralized by low energy electrons and then co-deposited with a rare gas on a 4 K sapphire window. Matrix samples were interrogated in situ by UV-optical a作者: infantile 時(shí)間: 2025-3-22 12:38 作者: 涂掉 時(shí)間: 2025-3-22 16:13 作者: 憤怒事實(shí) 時(shí)間: 2025-3-22 20:23 作者: HAWK 時(shí)間: 2025-3-23 00:41
Size-dependent thermodynamic properties of silver aggregates. Simulation of the photographic developonor whose electrochemical potential is close to those of usual photographic developers. A critical size has to be reached by the silver aggregate before it is thermodynamically able to accept electrons from the donor, then to grow by an autocatalytic process with alternate adsorption of Ag. ions an作者: Synchronism 時(shí)間: 2025-3-23 03:56

Binding energy of large icosahedral and cuboctahedral Lennard-Jones clustersl structures which have cuboctahedral fcc symmetry. It is of interest to understand the transition between this finite and bulk behavior. To model this transition in rare gas clusters we have undertaken optimization studies within the Lennard-Jones pair potential model. Using a combination of Monte 作者: 引起 時(shí)間: 2025-3-24 04:39

Size-dependent thermodynamic properties of silver aggregates. Simulation of the photographic developritical aggregate is ≈ ?0.4 V/NHE. The size-dependence of the electrochemical potential in an aqueous solution is discussed and compared with that of the ionization potential in the gas phase.
