Abstract:
The present invention is directed to self-assembled nanoparticle arrays, methods of making the nanoparticle arrays, and methods of using the nanoparticle arrays in spectroscopic methods for detecting targets of interest. The present invention is also directed to a fabrication method for surface-enhanced Raman scattering (SERS) substrates that possess a unique combination of three highly desirable attributes: (a) the SERS substrates can be tuned to match the laser wavelength of operation and maximize the enhancement factor for the particular Raman instrument and analyte in use; (b) the SERS substrates have a highly reproducible enhancement factor over macroscopic sampling areas; and (c) the fabrication method is achieved without resorting to expensive, slow nano-lithography tools.

Abstract:
A process for producing polymeric films by applying a liquid composition onto a surface of a substrate under vacuum conditions in a vacuum chamber. The composition has a first component which is polymerizable or crosslinkable in the presence of a sufficient amount of an acid; and a cationic photoinitiator which generates an acid upon exposure to ultraviolet radiation, electron beam radiation or both to cause polymerizing or crosslinking of the first component. A gas which emits ultraviolet radiation upon exposure to electron beam radiation is introduced into the vacuum chamber. The composition and the gas are exposed to electron beam radiation to cause the cationic photoinitiator to generate an amount of an acid to cause polymerizing or crosslinking of the first component. The composition is exposed to both electron beam radiation and gas-generated ultraviolet radiation and cured.

Abstract:
One aspect of the invention relates to a linker-free, one-step method of grafting polymer films onto organic substrates, and the films obtained by such a method. In certain embodiments, the grafted polymer films are conductive. In certain embodiments, said grafting method utilizes the ability for Friedel-Crafts catalyst to form radical cations from organic substrates. In one embodiment, the method provides poly-3,4-ethylenedioxythiophene (PEDOT) thin films grafted to organic substrates. In other embodiments, the method is applicable to the polymerization of other monomers to yield conducting polymers, such as polyanilines, polypyrroles, polyfurans, polythiophenes and their derivatives. Remarkably, the polymer films grafted by the inventive methods show enormous increases in adhesion strength. Further, in certain embodiments, polymer patterns were easily obtained using the inventive methods and soft lithography techniques. In certain embodiments, well-defined high-density line-and-space patterns were successfully obtained. In certain embodiments, e.g., when the polymer film is conducting, the obtained conducting polymer pattern grafted on common organic substrates can be used for integrated circuitry in flexible electronics.
Abstract:
The present invention relates to a method for forming a golf ball. The method comprises mixing a polyisocyanate crosslinker with a base TPU cover material, wherein the polyisocyanate crosslinker is aliphatic, miscible with the base TPU cover material and has functionalities greater than or equal to 2. The method further comprises dipping a golf ball in a catalyst solution, wherein the catalyst solution is allowed to absorb into a cover of the golf ball and heating the golf ball to allow continued diffusion of the catalyst solution into the cover of the golf ball.
