  • Processing and Characterization of Vacuum-Free CuInSe2 Thin Films from Nanoparticle-Precursors using Novel Temperature Treatment Techniques

    Processing and Characterization of Vacuum-Free CuInSe2 Thin Films from Nanoparticle-Precursors using Novel Temperature Treatment Techniques Matthias Schuster*, Philipp Sisterhenn, Lorenz Graf, Peter J. Wellmann Materials Department 6 (i-MEET), Martensstr. 7, 91058 Erlangen, Germany, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) The objective of this work is the processing and characterization of a dense CuInSe2 solar-cell-absorber-layer based on nanoparticulate precursors. Bimetallic copper-indium- and elemental selenium-nanoparticles were synthesized by wet-chemical processes and then dispersed in organic solvents as nano-inks. These inks were then printed into different…

  • Hydrophobically-modified Chitosan Microspheres for Release of Diosgenin

    Hydrophobically-modified Chitosan Microspheres for Release of Diosgenin Javier Perez Quinones1,*, Oliver Brüggemann1, Carlos Peniche Covas2 1,* Johannes Kepler University Linz, Institute of Polymer Chemistry, Altenberger Straße 69, 4040 Linz, Austria. 2 University of Havana, Center of Biomaterials, Ave. Universidad s/n entre G y Ronda, Vedado, 10400 La Habana, Cuba. Chitosan microspheres (CS) prepared by water-in-oil emulsion/glutaraldehyde cross-linking-evaporation and simple coacervation/cross-linking with sodium tripolyphosphate were covalently linked to diosgenin hemiesters. The diosgenin content found using elemental analysis was ca. 6 to…
