Dynamic and static light scattering studies on self-aggregation behavior of biodegradable amphiphilic poly(ethylene oxide)-poly[(R)-3-hydroxybutyrate]-poly(ethylene oxide) triblock copolymers in aqueous solution
Article Abstract:
The formation of polymeric micelles by two amphiphilic poly(ethylene oxide)-poly[(R)-3-hydroxybutyrate]-poly-(ethylene oxide) triblock copolymers was confirmed with fluorescence techniques and transmission electron microscopy. Dynamic light scattering analysis showed that the hydrodynamic radius of the monodistributed polymeric micelles increased with an increase in poly-(ethylene oxide) block length.

Toward the solution synthesis of the tetrahedral Au20 cluster
Article Abstract:
The observation in solution of tetrahedral Au20 cluster in coordination with eight PPh3 (Ph = phenyl) ligands is provided. It is theoretical observations suggest that large quantities of ligand-stabilized tetrahedral Au20 can be obtained, opening the door for exploring its anticipated novel chemical, optical, and catalytic properties.
