  • Non-contact spectroscopy system and process
    Patent number: 5841546
    Abstract: A non-contact spectroscopy system includes scanning head structure with transmitting optics for focusing radiation onto the surface of material to be analyzed, and receiving optics for collecting radiation reflected from the surface of the material and directing the reflected radiation onto optic fiber structure for transmission to spectroscopic analyzer structure.

  • Attenuated total reflectance sensing
    Patent number: 5585634
    Abstract: A radiation transmission optical fiber having a core and cladding for spectroscopic monitoring includes a transmission portion and a sensor portion; the transmission portion has a continuous core portion and a continuous cladding over the core portion; the sensor portion has the cladding removed from one side of the fiber and the core portion exposed from the same side leaving the continuous cladding intact over the opposite side of the core portion of the sensor.

  • Multicomponent systems based on polypyrrole
    Patent number: 4707527
    Abstract: Compositions based on polypyrrole are described having incorporated therein a polymer component having one or more segments wherein at least one segment is elastomeric. The polymer component is present in an amount of at least about 10 weight percent of the polypyrrole present. The compositions exhibit improved processing properties over those of polypyrrole. Also described is a process for producing the compositions in which a pyrrole compound is electrochemically polymerized in the presence of an at least partially dissolved polymer component having one or more segments wherein at least one segment is elastomeric.

  • Covalently coupled cofactor modified electrodes and methods of synthesis and use
    Patent number: 4704193
    Abstract: An electrically and covalently coupled cofactor modified electrode for mediating the heterogeneous or homogeneous catalysis of a biochemical reaction by an enzyme. The electrode coating comprises an imidazoleflavin derivative covalently bonded to the electrode surface. Methods for preparation and use of the modified electrode are also presented.
    Type: Grant

  • Multicomponent systems based on polythiophene
    Patent number: 4657985
    Abstract: Compositions based on polythiophene are described having incorporated therein a polyether, such as polytetrahydrofuran. The polyether is present in an amount of at least about 10 weight percent of the polythiophene present. The compositions exhibit improved mechanical integrity, processing properties, and d.c. electrical conductivity over polythiophene. A process for producing the compositions is also described in which a thiophene compound is electrochemically polymerized in the presence of a dissolved polyether.
