  • Patent number: 12196879
    Abstract: A method for generating ultrawideband pulsed microwave signals from optical field ionization of a gas with an ultrashort laser pulse, where the amplitude and frequency of the signals can be controlled via the characteristics of the laser pulse and/or the gas. The center frequency of the spectrum of the microwave signal can be controlled by changing the laser pulse energy. The amplitude of the microwave signal can be controlled by changing the wavelength of the laser pulses. The amplitude and frequency of the microwave signal can be tuned by controlling the pressure of the gas medium. The location at which the microwave signal is generated can be controlled by controlling the location at which the laser pulse creates a plasma. Interference among microwave signals resulting from multiple laser-produced plasmas can be used to construct an ultrawideband microwave signal having a predetermined amplitude and frequency.

  • Publication number: 20250012968
    Abstract: A method of making chalcogenide based polymeric materials and converting those materials into optical fiber preforms and polymeric optical fibers. The preforms and fibers comprise chalcogenide elements and crosslinking moieties. These fibers can be used as optical waveguides at infrared wavelengths where other polymer fibers do not operate. The optical waveguides are ideally suitable for applications requiring the transmission of low-power infrared light, but may also be useful for transmitting high-power light at visible or infrared wavelengths.

  • Publication number: 20240409967
    Abstract: Described herein is a chemoenzymatic route to produce the small molecule sebacic acid from the renewable feedstock, e.g. vegetable oil. In one embodiment, this involves treating the a starting material such vegetable oil with KMnO4, sodium thiocyanate, and acid to obtain sebacic acid. Yield could be improved by pretreating the starting material with a lipase and then with a linoleic acid isomerase obtained from Propionibacterium acnes to obtain trans-10, cis-12 conjugated linoleic acid (CLA). The sebacic acid can be further processed with lipase and 1-butanol to obtain dibutyl sebacate.
