Systematic control of [4 + 4] photocycloaddition of dysprosium phosphonates through fine-tuning of two different phosphonate ligands with alkyl substituents reveals a size dependent rate with remarkable changes in the luminescence and magnetic dynamics.

The Mean

A migration-driven aggregation model with catalyzed decline process of two species is proposed, in which migration-driven aggregation occurs between any two aggregates of the same species with the size-dependent rate kernel . Meanwhile, a monomer decline of A-species aggregates occurs under the catalysis by B-species aggregates with the catalyzed decline rate kernel . The kinetic behavior of A species is investigated by means of the mean-field theory, which is found to depending crucially on the catalysis rate kernel parameter μ: in case, the migration-driven aggregation reaction dominates the process, and the aggregate size distribution of A species approaches the conventional scaling form, and A species will survive in the end; while incase, the catalyzed decline reaction dominates the process, the aggregate size distribution of A aggregate does not scale, and A species will die out in the end.

Controllable Size

Knowledge of the function and structure of small metal clusters is one goal of research in catalysis. One important experimental parameter is cluster size. Ideally, one would like to produce metal clusters of regulated size in order to characterize size-dependent cluster properties.A source has been developed which is capable of producing microscopic metal clusters of controllable size (in the range 5-500 atoms) This source, the Multiple Expansion Cluster Source, with a Free Jet Deceleration Filter (MECS/FJDF) operates as follows. The bulk metal is heated in an oven to give controlled concentrations of monomer and dimer which were expanded sonically. These metal species were quenched and condensed in He and filtered to produce areosol particles of a controlled size as verified by mass spectrometer measurements. The clusters were caught on pre-mounted, clean carbon films. The grids were then transferred in air for microscopic examination. MECS/FJDF was used to produce two different sizes of silver clusters for this study: nominally Ag6 and Ag50.
