Overview of Interdisciplinary Research Group #1 (Functional Nanocomposites)<\/span><\/strong><\/p>\n

This research group is focused on the syntheses, characterization, and modeling of functional nanocomposites comprised of inorganic and organic phases with tailored nanostructures and chemistries for enhanced energy conversion\/management (e.g., for light-to-electrical conversion) and antimicrobial activity (e.g., for decontamination of fluids and surfaces). This group utilizes the integrated interdisciplinary efforts of the Sandhage (School of Materials Science & Engineering), Marder (School of Chemistry & Biochemistry), Kippelen (School of Electrical & Computer Engineering), and Kr\u00f6ger (School of Chemistry & Biochemistry; School of Materials Science & Engineering) groups for: tailoring inorganic and organic surfaces; developing bio-enabled and\/or synthetic layer-by-layer inorganic\/organic deposition processes; synthesizing modified or new functional organic dyes and organic semiconductors; and characterizing and modeling the optoelectronic and antimicrobial properties of the resulting inorganic\/organic composites.<\/p>\n
