  • Publication number: 20070125685
    Abstract: Methods for reducing calcium deposition along surfaces in contact with the water phase of a resolved water/oil emulsion are disclosed. High calcium crude oil and the like are contacted with a sequestrant to form a sequestered calcium containing complex that partitions to the water phase in the resolved emulsion. A specifically formulated polymeric deposit control agent is added to the water phase to inhibit calcium deposit formation therein and along surfaces in contact with the water phase.

  • Publication number: 20070092972
    Abstract: Embodiments of the invention provide self-contained phosphate sensors with an analyte-specific reagent and a pH-modifier. The analyte-specific reagent includes a molybdenum salt or metal complex and a dye. The self-contained phosphate sensors can be used either in aqueous or non-aqueous solution or as a solid-state device. These self-contained phosphate sensors require no post-addition reagents to determine phosphate concentrations and the phosphate determination test requires a reduced number of procedural steps. Moreover, the self-contained phosphate sensor provides enhanced sensitivity and faster response time. Embodiments of the invention also provide a method for determining phosphate concentrations in a sample. The phosphate concentration in a sample can be quantified using a calibration curve generated by testing samples with known phosphate concentrations.

  • Publication number: 20070092973
    Abstract: A method of quantitatively measuring the concentration of a chemical species in a sample solution with a sensor film. A hydrogel sensor film is prepared having a chemical composition comprising an indicator that changes its optical property in the ultra-violet, visible or near-infrared spectral range upon being exposed to the chemical species in the sample solution. The film is exposed to a fixed amount of the sample solution. The concentration of the chemical species in the sample solution is quantified using the average absorbance measured from the sensor film.

  • Publication number: 20060072444
    Abstract: A storage medium can comprise a substrate, a reflective layer disposed on a side of the substrate, and data. The substrate can comprise a thermoplastic and a light-mark formed from at least a portion of light-marking additive mixed with the thermoplastic, wherein an optical property of the light-marking additive at an optical drive read wavelength can change due to being contacted with a mark wavelength. A method for using a storage medium can comprise directing a reading device to detect an inspection area of the storage medium, and wherein the inspection area on an authentic medium has a light-mark in a substrate of the storage medium that forms an optically induced signature. The optically induced signature can be converted to a digital identification signature and the digital identification signature can be verified for authenticity.
