    摘要： Monolayer protected nanoclusters (MPCs) are described herein. The MPCs contain a cluster of atoms or molecules (e.g. core) having bound thereto a plurality of ligands (e.g., monolayer). The ligands can be bound covalently or semi-covalently bound to the cluster. The ligands are generally in the form of a monolayer or mixed monolayer. The monolayer or mixed monolayer contains a plurality of ligands. In one embodiment, the monolayer and/or mixed monolayer contains 1,4-dithiolate ligands. The MPCs described herein exhibit improved quantum efficiency allowing for single cluster emissions to be measured. Moreover, some embodiments of the MPCs described herein exhibit enhanced redox activity, including the ability to transfer a plurality of electrons, i.e., up to about 19 or up to about 30 electrons under controlled conditions, while displaying improved overall chemical stability. Such behavior can be utilized in catalysis and nanoelectronics applications.

    摘要： Compositions and methods of making a culture medium from a polymeric material are described herein. The method can include (a) depolymerizing and/or dispersing the polymeric material to obtain a depolymerized and/or dispersed residue, and (b) combining the depolymerized and/or dispersed residue with one or more adjuvants to form a culture medium. In some embodiments, the polymeric material can be a plastic article, such as a waste carpet material. Culture media prepared from the compositions and methods are also described. The culture media are suitable for culturing microorganisms including bacterium, algae, and fungus. The microorganisms can be used to produce a bioproduct such as a biopolymer, an enzyme, or a cellular metabolite.
