  • Patent number: 10355311
    Abstract: A fluoride ion battery includes a substantially lithium-free anode and cathode. At least one of the anode or cathode contains fluorine, and a substantially lithium-free liquid electrolyte is used for charge transport. The electrolyte is liquid at temperatures below about 200 degrees Celsius, and can be formed from an organic-soluble fluoride salt dissolved in selected classes of solvents.

  • Publication number: 20180364188
    Abstract: A sensor array comprising multiple discrete sensors for providing detection and prognosis of various diseases. The array is made up of multiple discrete sensors, each of which has a first and a second noble metal electrode on a silicon substrate, said electrodes separated by a gap. An electrically conductive pathway across the gap between the first and second noble electrodes is provided by a nano-network of functionalized polymer nanowires or carbon nanotubes (SWNTs) the arrangement providing a sensor. The multiple discrete sensors comprise a reference cell and multiple detection sensors functionalized using a panel of capture molecules to detect the same or different diseases or biological functions.

  • Publication number: 20180202964
    Abstract: The present invention relates to methods of forming modular chemiresistive sensors. The sensors preferably have two gold or platinum electrodes mounted on a silicon substrate with the electrodes connected to a power source and are separated by a gap of 0.5 to 4.0 ?m. Functionalized polymer nanowire or carbon nanotube span the gap between the electrodes and connect the electrodes electrically. The electrodes are further connected to a circuit board having a processor and data storage, where the processor measures current and voltage values between the electrodes and compares the current and voltage values with current and voltages values stored in the data storage and assigned to particular concentrations of a pre-determined substances.
