  • Patent number: 10710313
    Abstract: A microwave heating device includes a variable frequency microwave power supply, a waveguide launcher, and a fixture to contain a material to be heated, with the fixture located directly adjacent to the end of the launcher. All heating occurs in the near-field region, i.e., no cavity modes or standing waves are established within the fixture. This condition may be insured by keeping the thickness of the fixture or workpiece under one wavelength (at all microwave frequencies being used). The launcher is preferably a horn configured to spread the microwave power laterally over a selected area while maintaining a single propagating mode. The invention may be used to enhance catalytic reactions for research and other purposes. Alternatively, the invention may be configured to perform spot curing or repair operations involving adhesives and composites.

    Abstract: Disclosed are an ink composition including light-absorbing nanoparticles and a photonic crystal structure formed using the same. The ink composition may include inorganic particles; monomer; photoinitiator; and nanoparticles light-absorbing nanoparticles to provide the photonic crystal structure. As consequence, problems such as low color sharpness, which makes photonic crystals visible, and attaining high productivity may be eliminated. Moreover, white scattering can be reduced, and thus a distinctive color can be exhibited even when there is a difference between a reflection angle and an observation angle of light, thereby improving visibility.

  • Patent number: 9394390
    Abstract: A polyolefin is functionalized with two, three, or more terminal coumarin groups. When irradiated with longer wavelength ultraviolet light (e.g., 365 nanometers), the coumarin groups cyclodimerize to form a chain-extended or crosslinked polyolefin. The cyclodimerization can be reversed by irradiation with shorter wavelength ultraviolet light (e.g., 254 nanometers). When the crosslinked polyolefin is used to form a barrier layer in a light emitting diode or a photovoltaic device, scratches in the barrier layer cleave the cyclodimer groups and can be “healed” by irradiation to reduce or remove the scratches.

  • Publication number: 20150071707
    Abstract: A method and system for treating and strengthening material. One or more electron accelerators can be integrated with a mobile unit. The electron accelerators are positioned on the mobile unit to irradiate and treat in-situ, a material located proximate to the mobile unit, wherein irradiation of the material by the electron accelerators results in in-situ cross-linking or polymerization of the material and therefore a strengthening and increased durability of the material. The in-situ treatment of a road surface to toughen and strengthen the road surface constructed with standard asphalt construction can result in improved material properties of the surface, enhanced durability, and improved lifetime.
