  • Patent number: 10445880
    Abstract: Methods for label-free characterization of untagged molecules within a biological sample in-situ. The untagged molecules may be constituent of extracellular vesicles, and are excited in the biological sample with at least one wavelength band of light derived from a single stream of optical pulses. Light emitted by the untagged molecules by SHG, THG, 2PAF and 3PAF processes is detected. Separate measures of the biological sample corresponding to light emitted by the untagged molecules in each of the SHG, THG, 2PAF and 3PAF processes are derived. On that basis, normal extracellular vesicles may be differentiated from extracellular vesicles associated with a tumor on the basis of a specified signature of characteristics of images of SHG, THG, 2PAF and 3PAF processes.

  • Patent number: 10428171
    Abstract: The present invention relates to a one-component processing method and system for preparing polyurea materials. This method and system involves a polymerization process using cyclic oligomeric polyurea precursors. These cyclic oligomeric precursors have dynamic urea bonds such as hindered urea bonds (HUBs). These cyclic oligomeric precursors exhibit dynamic properties to reversibly dissociate in situ yielding isocyanate and amine components which polymerize to yield the polyureas, such as linear, branched or cross-linked polyureas. This method and system has advantages over conventional methods that utilize two-component systems. Such two-component systems require the segregation of the isocyanate and amine components to prevent premature or too rapid polymerization. The resulting polyureas are useful for a variety of applications including coatings.

  • Patent number: 10421072
    Abstract: Provided herein are methods and materials for the manufacture and use of wettability tracks on various substrates for rapid fluid transport and drainage, even in a condensing environment. The degree of wettability of the materials' surfaces range from superhydrophobic to superhydrophilic. The method centers on the formation of a dispersion of titanium dioxide and a fluoroacrylic co-polymer in an alcohol and water solution. The dispersion may then be deposited onto a surface to form a coating, which is then dried to evaporate the alcohol. The dried coating is exposed to radiation to produce a wedge-shaped track. The coating is exposed to the radiation through a photomask to produce the track. The radiation may be high energy, such as UV radiation. The radiation may be selectively exposed to designated areas on the coating. The hydrophilic wedge-shaped track may have a wedge angle of from 0 degrees to 45 degrees.

  • Patent number: 10416383
    Abstract: Methods and apparatus for concentrating light into a specified focal volume and for collecting light from a specified volume. Incident light is coupled through a plurality of successive transmissive asymmetric microstructure elements. The succession of transmissive asymmetric microstructure elements may be designed by representing an electromagnetic field as a linear combination of eigenmodes of one of the succession of transmissive asymmetric microstructure elements. The asymmetric microstructure elements are represented as a plurality of mesh lattice units and eigenmode solutions to Maxwell's equations are obtained for each mesh lattice unit subject to consistent boundary conditions. S-matrix formalism is employed to calculate a field output and weighting coefficients for the eigenmodes are selected to achieve a specified set of field output characteristics.

  • Patent number: 10414903
    Abstract: A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.
