  • Publication number: 20170053746
    Abstract: A planar mixed-metal perovskite solar cell can exhibit many favorable properties including high efficiencies and tunable electronic properties. The incorporation of different metal species (i.e. Co, Cu, Fe, Mg, Mn, Ni, Sn, Sr, and Zn) into the film is made possible by the solubility of either each metal's divalent acetate or halide compound in a solvent.

  • Publication number: 20170017069
    Abstract: System and method configured to operate under conditions when the object being imaged destroys or negates the information which otherwise allows the user to take advantage of optical parallax, configured to elicit luminescence from the same targets in the object as a result of irradiation of these targets with pump light at different, respectively corresponding wavelengths, and acquire optical data from so-illuminated targets through the very same optical path to image the object at different wavelengths. One embodiment enables acquisition, by the same optical detector and from the same object, of imaging data that includes a reflectance image and multiple fluorescence-based images caused by light at different wavelengths, to assess difference in depths of locations of targets within the object.

  • Patent number: 9274108
    Abstract: The invention is directed toward systems and methods for the formation of two dimensional monolayer structures of ordered biomacromolecules, such as viruses, atop cohesive polyelectrolyte multilayers to create functional thin films. Methods for the formation of such thin films are disclosed that involve an interdiffusion-induced assembly process of the biomacromolecules. The inventive systems provide a general platform for the systematic incorporation and assembly of organic, biological and inorganic materials and will enable many potential technological applications such as, for example, chemical and biological sensors, power devices and catalytic membranes.

  • Patent number: 9029286
    Abstract: A method of making a metal oxide nanoparticle comprising contacting an aqueous solution of a metal salt with an oxidant. The method is safe, environmentally benign, and uses readily available precursors. The size of the nanoparticles, which can be as small as 1 nm or smaller, can be controlled by selecting appropriate conditions. The method is compatible with biologically derived scaffolds, such as virus particles chosen to bind a desired material. The resulting nanoparticles can be porous and provide advantageous properties as a catalyst.

  • Patent number: 8859456
    Abstract: One-dimensional ring structures from M13 viruses were constructed by two genetic modifications encoding binding peptides and synthesis of a heterobifunctional linker molecule. The bifunctional viruses displayed an anti-streptavidin peptide and hexahistidine (SEQ ID NO:4) peptide at opposite ends of the virus as pIII and pIX fusions. Stoichiometric addition of the streptavidin-NiNTA linker molecule led to the reversible formation of virus-based nanorings with circumferences corresponding to lengths of the packagable DNAs. These virus-based ring structures can be further engineered to nucleate inorganic materials and form metallic, magnetic, or semiconductor nanorings using trifunctionalized viruses.
