  • Publication number: 20150283555
    Abstract: Certain exemplary embodiments can provide a method, which can comprise isolating a single molecule of a solid organic compound via a microencapsulation process. The single molecule can be adapted for use in at least one of a drug, pharmaceutical application, microelectronic device, bioengineering application, biomedical product, agricultural product, or agricultural medicine. The microencapsulation process can comprise (1) adsorbing the single molecule on a template; and (2) dividing the template into species using electrostatic charge generating molecules.

  • Patent number: 9091772
    Abstract: A method, apparatus, and computer program products for controlling gain in a scintillation detector. Calibration count rates, each representing an integral count rate above a different threshold, are obtained from a photomultiplier tube. Photomultiplier tube gain is adjusted if a result from evaluating a relationship of calibration count rates varies from an expected result based on integral count rate versus threshold for a reference peak in the energy spectrum of the radiation source. An additional, different relationship may also be evaluated and an additional gain adjustment performed when a result indicates that the calibration count rates are not from the reference peak. A same radiation source may be used for collecting test counts and calibration counts.

  • Publication number: 20150099214
    Abstract: Certain exemplary embodiments can provide a graphene hybrid composite (GHC). The GHC can be formed between specific nano carbon materials and graphene generated via pyrolysis of solid carbon sources. A Raman spectrum of the GHC can show a major 2D band at approximately 2650 cm?1, a minor D and G band at approximately 1350 cm?1 and approximately 1575 cm?1, and an intensity ratio of 2D band over D band and G band greater than 1.

  • Publication number: 20150060736
    Abstract: Certain exemplary embodiments can provide a system comprising a hybrid composite. The hybrid composite can comprise tubular carbon and graphene produced via pyrolysis of a milled solid carbon source under an unoxidizing environment. When analyzed via X-ray diffraction, the hybrid composite can generate peaks at two theta values of approximately 26.5 degrees, approximately 42.5 degrees, and/or approximately 54.5 degrees.
