  • ETCHING COMPOSITION
    Publication number: 20120180852
    Abstract: The invention relates to a chemical etching composition and to methods to produce a photovoltaic cell with transparent regions. The methods comprise a step to locally dispense an etching composition on the photovoltaic cell in a pattern, or adjacent to the edge thereof; an optional step to apply heat to the cell; and a step to remove the etching composition. The methods are further characterized by the chemical removal of one or more chemically distinctive layers of the photovoltaic cell where the etching composition is applied. The methods may be used to produce a thin film photovoltaic panel.

  • DEGRADABLE CROSSLINKED AMINATED DEXTRAN MICROSPHERES AND METHODS OF USE
    Publication number: 20110033548
    Abstract: Degradable, crosslinked aminated dextran microspheres are described. The microspheres contain aminated dextran crosslinked with a crosslinking agent having two or more functional groups that are capable of reacting with the primary amine groups of the aminated dextran to form covalent bonds. The degradable, crosslinked aminated dextran microspheres may be useful for temporary therapeutic embolization and drug delivery.
