  • Methods of separation of a metal from its liquid-soluble oxide for analysis
    Patent number: 10132788
    Abstract: Various methods for separating a metal from its metal oxide for analysis are provided. For example, exemplary methods include approaches for providing a process for separating a metal from its water-soluble metal oxide in a pyrotechnic composition. Exemplary embodiments include a method of separation that allows for analysis of both metal and metal oxide using an elemental analysis technique, (e.g., inductively coupled plasma optical emission spectrometry (ICP-OES)) and determination of the relative amount of elemental metal and its oxide known as speciation.

  • Thermally stable electro-optic device and method
    Patent number: 5708178
    Abstract: Novel acceptor-donor-acceptor and donor-acceptor-donor compounds for use in forming a thermally-stable electro-optic waveguide are disclosed. Also disclosed is a thermally stable waveguide material containing thermally stable acceptor-donor-acceptor or donor-acceptor-donor guest dipole compounds in a temperature-resistant polymer matrix. The waveguide has selected regions in which the net dipoles of the guest molecules are oriented, for electro-optic switching when an electric field is placed across these regions.

  • Thermally stable electro-optic device and method
    Patent number: 5414791
    Abstract: Novel acceptor-donor-acceptor compounds for use in forming a thermally-stable electro-optic waveguide are disclosed. Also disclosed is a thermally stable waveguide material containing thermally stable acceptor-donor-acceptor or donor-acceptor-donor guest dipole compounds in dissolved form in a polyimide matrix. The waveguide has selected regions in which the net dipoles of the guest molecules are oriented, for electro-optic switching when an electric field is placed across these regions.
